[PATCH 6.1 001/225] RDMA/bnxt_re: Fix the page_size used during the MR creation

[Greg Kroah-Hartman]

From: Selvin Xavier <selvin.xavier@broadcom.com>

[ Upstream commit 08c7f09356e45d093d1867c7a3c6ac6526e2f98b ]

Driver populates the list of pages used for Memory region wrongly when
page size is more than system page size. This is causing a failure when
some of the applications that creates MR with page size as 2M.  Since HW
can support multiple page sizes, pass the correct page size while creating
the MR.

Also, driver need not adjust the number of pages when HW Queues are
created with user memory. It should work with the number of dma blocks
returned by ib_umem_num_dma_blocks. Fix this calculation also.

Fixes: 0c4dcd602817 ("RDMA/bnxt_re: Refactor hardware queue memory allocation")

[PATCH 6.1 003/225] RDMA/efa: Fix unsupported page sizes in device

[Greg Kroah-Hartman]

From: Yonatan Nachum <ynachum@amazon.com>

[ Upstream commit 866422cdddcdf59d8c68e9472d49ba1be29b5fcf ]

Device uses 4KB size blocks for user pages indirect list while the
driver creates those blocks with the size of PAGE_SIZE of the kernel. On
kernels with PAGE_SIZE different than 4KB (ARM RHEL), this leads to a
failure on register MR with indirect list because of the miss
communication between driver and device.

[PATCH 6.1 005/225] RDMA/hns: Fix base address table allocation

[Greg Kroah-Hartman]

From: Chengchang Tang <tangchengchang@huawei.com>

[ Upstream commit 7f3969b14f356dd65fa95b3528eb05c32e68bc06 ]

For hns, the specification of an entry like resource (E.g. WQE/CQE/EQE)
depends on BT page size, buf page size and hopnum. For user mode, the buf
page size depends on UMEM. Therefore, the actual specification is
controlled by BT page size and hopnum.

The current BT page size and hopnum are obtained from firmware. This makes
the driver inflexible and introduces unnecessary constraints.  Resource
allocation failures occur in many scenarios.

This patch will calculate whether the BT page size set by firmware is
sufficient before allocating BT, and increase the BT page size if it is
insufficient.

[PATCH 6.1 006/225] RDMA/hns: Modify the value of long message loopback slice

[Greg Kroah-Hartman]

From: Yangyang Li <liyangyang20@huawei.com>

[ Upstream commit 56518a603fd2bf74762d176ac980572db84a3e14 ]

Long message loopback slice is used for achieving traffic balance between
QPs. It prevents the problem that QPs with large traffic occupying the
hardware pipeline for a long time and QPs with small traffic cannot be
scheduled.

Currently, its maximum value is set to 16K, which means only after a QP
sends 16K will the second QP be scheduled. This value is too large, which
will lead to unbalanced traffic scheduling, and thus it needs to be
modified.

The setting range of the long message loopback slice is modified to be
from 1024 (the lower limit supported by hardware) to mtu. Actual testing
shows that this value can significantly reduce error in hardware traffic
scheduling.

This solution is compatible with both HIP08 and HIP09. The modified
lp_pktn_ini has a maximum value of 2 (when mtu is 256), so the range
checking code for lp_pktn_ini is no longer necessary and needs to be
deleted.

[PATCH 6.1 007/225] dmaengine: at_xdmac: fix potential Oops in at_xdmac_prep_interleaved()

[Greg Kroah-Hartman]

From: Dan Carpenter <dan.carpenter@linaro.org>

[ Upstream commit 4d43acb145c363626d76f49febb4240c488cd1cf ]

There are two place if the at_xdmac_interleaved_queue_desc() fails which
could lead to a NULL dereference where "first" is NULL and we call
list_add_tail(&first->desc_node, ...).  In the first caller, the return
is not checked so add a check for that.  In the next caller, the return
is checked but if it fails on the first iteration through the loop then
it will lead to a NULL pointer dereference.

Smatch complains that
drivers/iommu/rockchip-iommu.c:1306 rk_iommu_probe() warn: missing unwind goto?

The rk_iommu_probe function, after obtaining the irq value through
platform_get_irq, directly returns an error if the returned value
is negative, without releasing any resources.

Fix this by adding a new error handling label "err_pm_disable" and
use a goto statement to redirect to the error handling process. In
order to preserve the original semantics, set err to the value of irq.

[PATCH 6.1 011/225] iommu/amd: Dont block updates to GATag if guest mode is on

[Greg Kroah-Hartman]

From: Joao Martins <joao.m.martins@oracle.com>

[ Upstream commit ed8a2f4ddef2eaaf864ab1efbbca9788187036ab ]

On KVM GSI routing table updates, specially those where they have vIOMMUs
with interrupt remapping enabled (to boot >255vcpus setups without relying
on KVM_FEATURE_MSI_EXT_DEST_ID), a VMM may update the backing VF MSIs
with a new VCPU affinity.

On AMD with AVIC enabled, the new vcpu affinity info is updated via:
	avic_pi_update_irte()
		irq_set_vcpu_affinity()
			amd_ir_set_vcpu_affinity()
				amd_iommu_{de}activate_guest_mode()

Where the IRTE[GATag] is updated with the new vcpu affinity. The GATag
contains VM ID and VCPU ID, and is used by IOMMU hardware to signal KVM
(via GALog) when interrupt cannot be delivered due to vCPU is in
blocking state.

The issue is that amd_iommu_activate_guest_mode() will essentially
only change IRTE fields on transitions from non-guest-mode to guest-mode
and otherwise returns *with no changes to IRTE* on already configured
guest-mode interrupts. To the guest this means that the VF interrupts
remain affined to the first vCPU they were first configured, and guest
will be unable to issue VF interrupts and receive messages like this
from spurious interrupts (e.g. from waking the wrong vCPU in GALog):

[  167.759472] __common_interrupt: 3.34 No irq handler for vector
[  230.680927] mlx5_core 0000:00:02.0: mlx5_cmd_eq_recover:247:(pid
3122): Recovered 1 EQEs on cmd_eq
[  230.681799] mlx5_core 0000:00:02.0:
wait_func_handle_exec_timeout:1113:(pid 3122): cmd[0]: CREATE_CQ(0x400)
recovered after timeout
[  230.683266] __common_interrupt: 3.34 No irq handler for vector

Given the fact that amd_ir_set_vcpu_affinity() uses
amd_iommu_activate_guest_mode() underneath it essentially means that VCPU
affinity changes of IRTEs are nops. Fix it by dropping the check for
guest-mode at amd_iommu_activate_guest_mode(). Same thing is applicable to
amd_iommu_deactivate_guest_mode() although, even if the IRTE doesn't change
underlying DestID on the host, the VFIO IRQ handler will still be able to
poke at the right guest-vCPU.

[PATCH 6.1 012/225] iommu/amd: Handle GALog overflows

[Greg Kroah-Hartman]

From: Joao Martins <joao.m.martins@oracle.com>

[ Upstream commit af47b0a24058e56e983881993752f88288ca6511 ]

GALog exists to propagate interrupts into all vCPUs in the system when
interrupts are marked as non running (e.g. when vCPUs aren't running). A
GALog overflow happens when there's in no space in the log to record the
GATag of the interrupt. So when the GALOverflow condition happens, the
GALog queue is processed and the GALog is restarted, as the IOMMU
manual indicates in section "2.7.4 Guest Virtual APIC Log Restart
Procedure":

| * Wait until MMIO Offset 2020h[GALogRun]=0b so that all request
|   entries are completed as circumstances allow. GALogRun must be 0b to
|   modify the guest virtual APIC log registers safely.
| * Write MMIO Offset 0018h[GALogEn]=0b.
| * As necessary, change the following values (e.g., to relocate or
| resize the guest virtual APIC event log):
|   - the Guest Virtual APIC Log Base Address Register
|      [MMIO Offset 00E0h],
|   - the Guest Virtual APIC Log Head Pointer Register
|      [MMIO Offset 2040h][GALogHead], and
|   - the Guest Virtual APIC Log Tail Pointer Register
|      [MMIO Offset 2048h][GALogTail].
| * Write MMIO Offset 2020h[GALOverflow] = 1b to clear the bit (W1C).
| * Write MMIO Offset 0018h[GALogEn] = 1b, and either set
|   MMIO Offset 0018h[GAIntEn] to enable the GA log interrupt or clear
|   the bit to disable it.

Failing to handle the GALog overflow means that none of the VFs (in any
guest) will work with IOMMU AVIC forcing the user to power cycle the
host. When handling the event it resumes the GALog without resizing
much like how it is done in the event handler overflow. The
[MMIO Offset 2020h][GALOverflow] bit might be set in status register
without the [MMIO Offset 2020h][GAInt] bit, so when deciding to poll
for GA events (to clear space in the galog), also check the overflow
bit.

From: Jeff Layton <jlayton@kernel.org>

[ Upstream commit d53d70084d27f56bcdf5074328f2c9ec861be596 ]

notify_change can modify the iattr structure. In particular it can
end up setting ATTR_MODE when ATTR_KILL_SUID is already set, causing
a BUG() if the same iattr is passed to notify_change more than once.

[PATCH 6.1 015/225] dmaengine: pl330: rename _start to prevent build error

From: Randy Dunlap <rdunlap@infradead.org>

[ Upstream commit a1a5f2c887252dec161c1e12e04303ca9ba56fa9 ]

"_start" is used in several arches and proably should be reserved
for ARCH usage. Using it in a driver for a private symbol can cause
a build error when it conflicts with ARCH usage of the same symbol.

Therefore rename pl330's "_start" to "pl330_start_thread" so that there
is no conflict and no build error.

[PATCH 6.1 020/225] net/mlx5e: Dont attach netdev profile while handling internal error

[Greg Kroah-Hartman]

From: Dmytro Linkin <dlinkin@nvidia.com>

[ Upstream commit bdf274750fca17b289404ef03453c4070725302c ]

As part of switchdev mode disablement, driver changes port netdevice
profile from uplink to nic. If this process is triggered by health
recovery flow (PCI reset, for ex.) profile attach would fail because all
fw commands aborted when internal error flag is set. As a result, nic
netdevice profile is not attached and driver fails to rollback to uplink
profile, which leave driver in broken state and cause crash later.

To handle broken state do netdevice profile initialization only instead
of full attachment and release mdev resources on driver suspend as
expected. Actual netdevice attachment is done during driver load.

[PATCH 6.1 022/225] netrom: fix info-leak in nr_write_internal()

[Greg Kroah-Hartman]

From: Eric Dumazet <edumazet@google.com>

[ Upstream commit 31642e7089df8fd3f54ca7843f7ee2952978cad1 ]

Simon Kapadia reported the following issue:

<quote>

The Online Amateur Radio Community (OARC) has recently been experimenting
with building a nationwide packet network in the UK.
As part of our experimentation, we have been testing out packet on 300bps HF,
and playing with net/rom.  For HF packet at this baud rate you really need
to make sure that your MTU is relatively low; AX.25 suggests a PACLEN of 60,
and a net/rom PACLEN of 40 to go with that.
However the Linux net/rom support didn't work with a low PACLEN;
the mkiss module would truncate packets if you set the PACLEN below about 200 or so, e.g.:

Apr 19 14:00:51 radio kernel: [12985.747310] mkiss: ax1: truncating oversized transmit packet!

This didn't make any sense to me (if the packets are smaller why would they
be truncated?) so I started investigating.
I looked at the packets using ethereal, and found that many were just huge
compared to what I would expect.
A simple net/rom connection request packet had the request and then a bunch
of what appeared to be random data following it:

Simon provided a patch that I slightly revised:
Not only we must not use skb_tailroom(), we also do
not want to count NR_NETWORK_LEN twice.

[PATCH 6.1 023/225] af_packet: Fix data-races of pkt_sk(sk)->num.

[Greg Kroah-Hartman]

From: Kuniyuki Iwashima <kuniyu@amazon.com>

[ Upstream commit 822b5a1c17df7e338b9f05d1cfe5764e37c7f74f ]

syzkaller found a data race of pkt_sk(sk)->num.

The value is changed under lock_sock() and po->bind_lock, so we
need READ_ONCE() to access pkt_sk(sk)->num without these locks in
packet_bind_spkt(), packet_bind(), and sk_diag_fill().

Note that WRITE_ONCE() is already added by commit c7d2ef5dd4b0
("net/packet: annotate accesses to po->bind").

[PATCH 6.1 024/225] tls: improve lockless access safety of tls_err_abort()

[Greg Kroah-Hartman]

From: Jakub Kicinski <kuba@kernel.org>

[ Upstream commit 8a0d57df8938e9fd2e99d47a85b7f37d86f91097 ]

Most protos' poll() methods insert a memory barrier between
writes to sk_err and sk_error_report(). This dates back to
commit a4d258036ed9 ("tcp: Fix race in tcp_poll").

I guess we should do the same thing in TLS, tcp_poll() does
not hold the socket lock.

[PATCH 6.1 025/225] amd-xgbe: fix the false linkup in xgbe_phy_status

[Greg Kroah-Hartman]

From: Raju Rangoju <Raju.Rangoju@amd.com>

[ Upstream commit dc362e20cd6ab7a93d1b09669730c406f0910c35 ]

In the event of a change in XGBE mode, the current auto-negotiation
needs to be reset and the AN cycle needs to be re-triggerred. However,
the current code ignores the return value of xgbe_set_mode(), leading to
false information as the link is declared without checking the status
register.

Fix this by propagating the mode switch status information to
xgbe_phy_status().

[PATCH 6.1 028/225] RDMA/irdma: Prevent QP use after free

[Greg Kroah-Hartman]

From: Mustafa Ismail <mustafa.ismail@intel.com>

[ Upstream commit c8f304d75f6c6cc679a73f89591f9a915da38f09 ]

There is a window where the poll cq may use a QP that has been freed.
This can happen if a CQE is polled before irdma_clean_cqes() can clear the
CQE's related to the QP and the destroy QP races to free the QP memory.
then the QP structures are used in irdma_poll_cq.  Fix this by moving the
clearing of CQE's before the reference is removed and the QP is destroyed.

[PATCH 6.1 029/225] RDMA/irdma: Fix Local Invalidate fencing

[Greg Kroah-Hartman]

From: Mustafa Ismail <mustafa.ismail@intel.com>

[ Upstream commit 5842d1d9c1b0d17e0c29eae65ae1f245f83682dd ]

If the local invalidate fence is indicated in the WR, only the read fence
is currently being set in WQE. Fix this to set both the read and local
fence in the WQE.

[PATCH 6.1 030/225] af_packet: do not use READ_ONCE() in packet_bind()

[Greg Kroah-Hartman]

From: Eric Dumazet <edumazet@google.com>

[ Upstream commit 6ffc57ea004234d9373c57b204fd10370a69f392 ]

A recent patch added READ_ONCE() in packet_bind() and packet_bind_spkt()

This is better handled by reading pkt_sk(sk)->num later
in packet_do_bind() while appropriate lock is held.

READ_ONCE() in writers are often an evidence of something being wrong.

[PATCH 6.1 031/225] tcp: deny tcp_disconnect() when threads are waiting

[Greg Kroah-Hartman]

From: Eric Dumazet <edumazet@google.com>

[ Upstream commit 4faeee0cf8a5d88d63cdbc3bab124fb0e6aed08c ]

Historically connect(AF_UNSPEC) has been abused by syzkaller
and other fuzzers to trigger various bugs.

A recent one triggers a divide-by-zero [1], and Paolo Abeni
was able to diagnose the issue.

tcp_recvmsg_locked() has tests about sk_state being not TCP_LISTEN
and TCP REPAIR mode being not used.

Then later if socket lock is released in sk_wait_data(),
another thread can call connect(AF_UNSPEC), then make this
socket a TCP listener.

When recvmsg() is resumed, it can eventually call tcp_cleanup_rbuf()
and attempt a divide by 0 in tcp_rcv_space_adjust() [1]

This patch adds a new socket field, counting number of threads
blocked in sk_wait_event() and inet_wait_for_connect().

If this counter is not zero, tcp_disconnect() returns an error.

This patch adds code in blocking socket system calls, thus should
not hurt performance of non blocking ones.

Note that we probably could revert commit 499350a5a6e7 ("tcp:
initialize rcv_mss to TCP_MIN_MSS instead of 0") to restore
original tcpi_rcv_mss meaning (was 0 if no payload was ever
received on a socket)

[PATCH 6.1 032/225] tcp: Return user_mss for TCP_MAXSEG in CLOSE/LISTEN state if user_mss set

[Greg Kroah-Hartman]

From: Cambda Zhu <cambda@linux.alibaba.com>

[ Upstream commit 34dfde4ad87b84d21278a7e19d92b5b2c68e6c4d ]

This patch replaces the tp->mss_cache check in getting TCP_MAXSEG
with tp->rx_opt.user_mss check for CLOSE/LISTEN sock. Since
tp->mss_cache is initialized with TCP_MSS_DEFAULT, checking if
it's zero is probably a bug.

With this change, getting TCP_MAXSEG before connecting will return
default MSS normally, and return user_mss if user_mss is set.

When an alernate RNIC is available in system, SMC will try to add a new
link based on the RNIC for resilience. All the RMBs in use will be mapped
to the new link. Then the RMBs' MRs corresponding to the new link will be
filled into SMCRv2 LLC ADD LINK messages.

However, smc_llc_fill_ext_v2() mistakenly accesses to unused RMBs which
haven't been mapped to the new link and have no valid MRs, thus causing
a crash. So this patch fixes the logic.

[PATCH 6.1 037/225] net/sched: Reserve TC_H_INGRESS (TC_H_CLSACT) for ingress (clsact) Qdiscs

[Greg Kroah-Hartman]

From: Peilin Ye <peilin.ye@bytedance.com>

[ Upstream commit f85fa45d4a9408d98c46c8fa45ba2e3b2f4bf219 ]

Currently it is possible to add e.g. an HTB Qdisc under ffff:fff1
(TC_H_INGRESS, TC_H_CLSACT):

  $ ip link add name ifb0 type ifb
  $ tc qdisc add dev ifb0 parent ffff:fff1 htb
  $ tc qdisc add dev ifb0 clsact
  Error: Exclusivity flag on, cannot modify.
  $ drgn
  ...
  >>> ifb0 = netdev_get_by_name(prog, "ifb0")
  >>> qdisc = ifb0.ingress_queue.qdisc_sleeping
  >>> print(qdisc.ops.id.string_().decode())
  htb
  >>> qdisc.flags.value_() # TCQ_F_INGRESS
  2

Only allow ingress and clsact Qdiscs under ffff:fff1.  Return -EINVAL
for everything else.  Make TCQ_F_INGRESS a static flag of ingress and
clsact Qdiscs.

[PATCH 6.1 038/225] net/sched: Prohibit regrafting ingress or clsact Qdiscs

[Greg Kroah-Hartman]

From: Peilin Ye <peilin.ye@bytedance.com>

[ Upstream commit 9de95df5d15baa956c2b70b9e794842e790a8a13 ]

Currently, after creating an ingress (or clsact) Qdisc and grafting it
under TC_H_INGRESS (TC_H_CLSACT), it is possible to graft it again under
e.g. a TBF Qdisc:

  $ ip link add ifb0 type ifb
  $ tc qdisc add dev ifb0 handle 1: root tbf rate 20kbit buffer 1600 limit 3000
  $ tc qdisc add dev ifb0 clsact
  $ tc qdisc link dev ifb0 handle ffff: parent 1:1
  $ tc qdisc show dev ifb0
  qdisc tbf 1: root refcnt 2 rate 20Kbit burst 1600b lat 560.0ms
  qdisc clsact ffff: parent ffff:fff1 refcnt 2
                                      ^^^^^^^^

clsact's refcount has increased: it is now grafted under both
TC_H_CLSACT and 1:1.

ingress and clsact Qdiscs should only be used under TC_H_INGRESS
(TC_H_CLSACT).  Prohibit regrafting them.

This is because when mq is added for the first time, qdiscs in mq is set
to NULL in mq_attach(). Therefore, when replacing mq after adding mq, we
need to initialize qdiscs in the mq before continuing to graft. Otherwise,
it will couse NULL pointer dereference issue in mq_attach(). And the same
issue will occur in the attach functions of mqprio, taprio and htb.
ffff:fff1 means that the repalce qdisc is ingress. Ingress does not allow
any qdisc to be attached. Therefore, ffff:fff1 is incorrectly used, and
the command should be dropped.

[ Upstream commit f4e4534850a9d18c250a93f8d7fbb51310828110 ]

The current code for the length calculation wrongly truncates the reported

groups. To fix this, use 'BITS_TO_BYTES()' which rounds up the

[PATCH 6.1 042/225] nfsd: fix double fget() bug in __write_ports_addfd()

[Greg Kroah-Hartman]

From: Dan Carpenter <dan.carpenter@linaro.org>

[ Upstream commit c034203b6a9dae6751ef4371c18cb77983e30c28 ]

The bug here is that you cannot rely on getting the same socket
from multiple calls to fget() because userspace can influence
that.  This is a kind of double fetch bug.

The fix is to delete the svc_alien_sock() function and instead do
the checking inside the svc_addsock() function.

[PATCH 6.1 046/225] iommu/mediatek: Flush IOTLB completely only if domain has been attached

[Greg Kroah-Hartman]

From: Chen-Yu Tsai <wenst@chromium.org>

[ Upstream commit b3fc95709c54ffbe80f16801e0a792a4d2b3d55e ]

If an IOMMU domain was never attached, it lacks any linkage to the
actual IOMMU hardware. Attempting to do flush_iotlb_all() on it will
result in a NULL pointer dereference. This seems to happen after the
recent IOMMU core rework in v6.4-rc1.

    Unable to handle kernel read from unreadable memory at virtual address 0000000000000018
    Call trace:
     mtk_iommu_flush_iotlb_all+0x20/0x80
     iommu_create_device_direct_mappings.part.0+0x13c/0x230

Check if the "bank" field has been filled in before actually attempting
the IOTLB flush to avoid it. The IOTLB is also flushed when the device
comes out of runtime suspend, so it should have a clean initial state.

[PATCH 6.1 048/225] tcp: fix mishandling when the sack compression is deferred.

[Greg Kroah-Hartman]

From: fuyuanli <fuyuanli@didiglobal.com>

[ Upstream commit 30c6f0bf9579debce27e45fac34fdc97e46acacc ]

In this patch, we mainly try to handle sending a compressed ack
correctly if it's deferred.

Here are more details in the old logic:
When sack compression is triggered in the tcp_compressed_ack_kick(),
if the sock is owned by user, it will set TCP_DELACK_TIMER_DEFERRED
and then defer to the release cb phrase. Later once user releases
the sock, tcp_delack_timer_handler() should send a ack as expected,
which, however, cannot happen due to lack of ICSK_ACK_TIMER flag.
Therefore, the receiver would not sent an ack until the sender's
retransmission timeout. It definitely increases unnecessary latency.

[PATCH 6.1 049/225] net: dsa: mv88e6xxx: Increase wait after reset deactivation

[Greg Kroah-Hartman]

From: Andreas Svensson <andreas.svensson@axis.com>

[ Upstream commit 3c27f3d53d588618d81d30d6712459a3cc9489b8 ]

A switch held in reset by default needs to wait longer until we can
reliably detect it.

An issue was observed when testing on the Marvell 88E6393X (Link Street).
The driver failed to detect the switch on some upstarts. Increasing the
wait time after reset deactivation solves this issue.

The updated wait time is now also the same as the wait time in the
mv88e6xxx_hardware_reset function.

[PATCH 6.1 050/225] mtd: rawnand: marvell: ensure timing values are written

[Greg Kroah-Hartman]

From: Chris Packham <chris.packham@alliedtelesis.co.nz>

[ Upstream commit 8a6f4d346f3bad9c68b4a87701eb3f7978542d57 ]

When new timing values are calculated in marvell_nfc_setup_interface()
ensure that they will be applied in marvell_nfc_select_target() by
clearing the selected_chip pointer.

[PATCH 6.1 051/225] mtd: rawnand: marvell: dont set the NAND frequency select

[Greg Kroah-Hartman]

From: Chris Packham <chris.packham@alliedtelesis.co.nz>

[ Upstream commit c4d28e30a8d0b979e4029465ab8f312ab6ce2644 ]

marvell_nfc_setup_interface() uses the frequency retrieved from the
clock associated with the nand interface to determine the timings that
will be used. By changing the NAND frequency select without reflecting
this in the clock configuration this means that the timings calculated
don't correctly meet the requirements of the NAND chip. This hasn't been
an issue up to now because of a different bug that was stopping the
timings being updated after they were initially set.

[PATCH 6.1 052/225] rtnetlink: call validate_linkmsg in rtnl_create_link

[Greg Kroah-Hartman]

From: Xin Long <lucien.xin@gmail.com>

commit b0ad3c179059089d809b477a1d445c1183a7b8fe upstream.

validate_linkmsg() was introduced by commit 1840bb13c22f5b ("[RTNL]:
Validate hardware and broadcast address attribute for RTM_NEWLINK")
to validate tb[IFLA_ADDRESS/BROADCAST] for existing links. The same
check should also be done for newly created links.

This patch adds validate_linkmsg() call in rtnl_create_link(), to
avoid the invalid address set when creating some devices like:

  # ip link add dummy0 type dummy
  # ip link add link dummy0 name mac0 address 01:02 type macsec

[PATCH 6.1 053/225] mptcp: avoid unneeded __mptcp_nmpc_socket() usage

[Greg Kroah-Hartman]

From: Paolo Abeni <pabeni@redhat.com>

[ Upstream commit 617612316953093bc859890e405e1b550c27d840 ]

In a few spots, the mptcp code invokes the __mptcp_nmpc_socket() helper
multiple times under the same socket lock scope. Additionally, in such
places, the socket status ensures that there is no MP capable handshake
running.

Under the above condition we can replace the later __mptcp_nmpc_socket()
helper invocation with direct access to the msk->subflow pointer and
better document such access is not supposed to fail with WARN().

[PATCH 6.1 054/225] mptcp: add annotations around msk->subflow accesses

[Greg Kroah-Hartman]

From: Paolo Abeni <pabeni@redhat.com>

[ Upstream commit 5b825727d0871b23e8867f6371183e61628b4a26 ]

The MPTCP can access the first subflow socket in a few spots
outside the socket lock scope. That is actually safe, as MPTCP
will delete the socket itself only after the msk sock close().

Still the such accesses causes a few KCSAN splats, as reported
by Christoph. Silence the harmless warning adding a few annotation
around the relevant accesses.

[PATCH 6.1 057/225] mptcp: consolidate passive msk socket initialization

[Greg Kroah-Hartman]

From: Paolo Abeni <pabeni@redhat.com>

[ Upstream commit 7e8b88ec35eef363040e08d99536d2bebef83774 ]

When the msk socket is cloned at MPC handshake time, a few
fields are initialized in a racy way outside mptcp_sk_clone()
and the msk socket lock.

The above is due historical reasons: before commit a88d0092b24b
("mptcp: simplify subflow_syn_recv_sock()") as the first subflow socket
carrying all the needed date was not available yet at msk creation
time

We can now refactor the code moving the missing initialization bit
under the socket lock, removing the init race and avoiding some
code duplication.

This will also simplify the next patch, as all msk->first write
access are now under the msk socket lock.

[PATCH 6.1 058/225] mptcp: fix data race around msk->first access

[Greg Kroah-Hartman]

From: Paolo Abeni <pabeni@redhat.com>

[ Upstream commit 1b1b43ee7a208096ecd79e626f2fc90d4a321111 ]

The first subflow socket is accessed outside the msk socket lock
by mptcp_subflow_fail(), we need to annotate each write access
with WRITE_ONCE, but a few spots still lacks it.

Fixes: 76a13b315709 ("mptcp: invoke MP_FAIL response when needed")

[PATCH 6.1 059/225] mptcp: add annotations around sk->sk_shutdown accesses

From: Paolo Abeni <pabeni@redhat.com>

[ Upstream commit 6b9831bfd9322b297eb6d44257808cc055fdc586 ]

Christoph reported the mptcp variant of a recently addressed plain
TCP issue. Similar to commit e14cadfd80d7 ("tcp: add annotations around
sk->sk_shutdown accesses") add READ/WRITE ONCE annotations to silence
KCSAN reports around lockless sk_shutdown access.

[PATCH 6.1 060/225] drm/amdgpu: release gpu full access after "amdgpu_device_ip_late_init"

[Greg Kroah-Hartman]

From: Chong Li <chongli2@amd.com>

[ Upstream commit 38eecbe086a4e52f54b2bbda8feba65d44addbef ]

[WHY]
 Function "amdgpu_irq_update()" called by "amdgpu_device_ip_late_init()" is an atomic context.
 We shouldn't access registers through KIQ since "msleep()" may be called in "amdgpu_kiq_rreg()".

[HOW]
 Move function "amdgpu_virt_release_full_gpu()" after function "amdgpu_device_ip_late_init()",
 to ensure that registers be accessed through RLCG instead of KIQ.

[PATCH 6.1 061/225] watchdog: menz069_wdt: fix watchdog initialisation

[Greg Kroah-Hartman]

From: Johannes Thumshirn <jth@kernel.org>

[ Upstream commit 87b22656ca6a896d0378e9e60ffccb0c82f48b08 ]

Doing a 'cat /dev/watchdog0' with menz069_wdt as watchdog0 will result in
a NULL pointer dereference.

This happens because we're passing the wrong pointer to
watchdog_register_device(). Fix this by getting rid of the static
watchdog_device structure and use the one embedded into the driver's
per-instance private data.

[PATCH 6.1 062/225] ALSA: hda: Glenfly: add HD Audio PCI IDs and HDMI Codec Vendor IDs.

[Greg Kroah-Hartman]

From: jasontao <jasontao@glenfly.com>

[ Upstream commit c51e431052e2eacfb23fbf6b39bc6c8770d9827a ]

Add a set of HD Audio PCI IDS, and the HDMI codec vendor IDs for
Glenfly Gpus.

- In default_bdl_pos_adj, set bdl to 128 as Glenfly Gpus have hardware
limitation, need to increase hdac interrupt interval.
- In azx_first_init, enable polling mode for Glenfly Gpu. When the codec
complete the command, it sends interrupt and writes response entries to
memory, howerver, the write requests sometimes are not actually
synchronized to memory when driver handle hdac interrupt on Glenfly Gpus.
If the RIRB status is not updated in the interrupt handler,
azx_rirb_get_response keeps trying to recevie a response from rirb until
1s timeout. Enabling polling mode for Glenfly Gpu can fix the issue.
- In patch_gf_hdmi, set Glenlfy Gpu Codec's no_sticky_stream as it need
driver to do actual clean-ups for the linked codec when switch from one
codec to another.

[PATCH 6.1 063/225] LoongArch: Relay BCE exceptions to userland as SIGSEGV with si_code=SEGV_BNDERR

[Greg Kroah-Hartman]

From: WANG Xuerui <git@xen0n.name>

[ Upstream commit c23e7f01cf621290770069d968ca4c8356a50d00 ]

SEGV_BNDERR was introduced initially for supporting the Intel MPX, but
fell into disuse after the MPX support was removed. The LoongArch
bounds-checking instructions behave very differently than MPX, but
overall the interface is still kind of suitable for conveying the
information to userland when bounds-checking assertions trigger, so we
wouldn't have to invent more UAPI. Specifically, when the BCE triggers,
a SEGV_BNDERR is sent to userland, with si_addr set to the out-of-bounds
address or value (in asrt{gt,le}'s case), and one of si_lower or
si_upper set to the configured bound depending on the faulting
instruction. The other bound is set to either 0 or ULONG_MAX to resemble
a range with both lower and upper bounds.

Note that it is possible to have si_addr == si_lower in case of a
failing asrtgt or {ld,st}gt, because those instructions test for strict
greater-than relationship. This should not pose a problem for userland,
though, because the faulting PC is available for the application to
associate back to the exact instruction for figuring out the
expectation.

Example exception context generated by a faulting `asrtgt.d t0, t1`
(assert t0 > t1 or BCE) with t0=100 and t1=200:

[PATCH 6.1 064/225] ASoC: Intel: soc-acpi-cht: Add quirk for Nextbook Ares 8A tablet

[Greg Kroah-Hartman]

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit ec6f82b4c63cc68f8dc03316e725106d242706be ]

The Nextbook Ares 8A tablet which has Android as factory OS, has a buggy
DSDT with both ESSX8316 and 10EC5651 ACPI devices.

This tablet actually uses an rt5651 codec, but the matching code ends up
picking the ESSX8316 device, add a quirk to ignote the ESSX8316 device
on this tablet.

[PATCH 6.1 065/225] drm/amdgpu: Use the default reset when loading or reloading the driver

From: lyndonli <Lyndon.Li@amd.com>

Below call trace and errors are observed when reloading
amdgpu driver with the module parameter reset_method=3.

It should do a default reset when loading or reloading the
driver, regardless of the module parameter reset_method.

From: Lee Jones <lee@kernel.org>

[ Upstream commit 2d1e952a2b8e5e92d8d55ac88a7cf7ca5ea591ad ]

If a user can make copy_from_user() fail, there is a potential for
UAF/DF due to a lack of locking around the allocation, use and freeing
of the data buffers.

This issue is not theoretical.  I managed to author a POC for it:

[PATCH 6.1 068/225] btrfs: abort transaction when sibling keys check fails for leaves

[Greg Kroah-Hartman]

From: Filipe Manana <fdmanana@suse.com>

[ Upstream commit 9ae5afd02a03d4e22a17a9609b19400b77c36273 ]

If the sibling keys check fails before we move keys from one sibling
leaf to another, we are not aborting the transaction - we leave that to
some higher level caller of btrfs_search_slot() (or anything else that
uses it to insert items into a b+tree).

This means that the transaction abort will provide a stack trace that
omits the b+tree modification call chain. So change this to immediately
abort the transaction and therefore get a more useful stack trace that
shows us the call chain in the bt+tree modification code.

It's also important to immediately abort the transaction just in case
some higher level caller is not doing it, as this indicates a very
serious corruption and we should stop the possibility of doing further
damage.

[PATCH 6.1 069/225] ARM: 9295/1: unwind:fix unwind abort for uleb128 case

[Greg Kroah-Hartman]

From: Haibo Li <haibo.li@mediatek.com>

[ Upstream commit fa3eeb638de0c1a9d2d860e5b48259facdd65176 ]

When unwind instruction is 0xb2,the subsequent instructions
are uleb128 bytes.
For now,it uses only the first uleb128 byte in code.

For vsp increments of 0x204~0x400,use one uleb128 byte like below:
0xc06a00e4 <unwind_test_work>: 0x80b27fac
  Compact model index: 0
  0xb2 0x7f vsp = vsp + 1024
  0xac      pop {r4, r5, r6, r7, r8, r14}

For vsp increments larger than 0x400,use two uleb128 bytes like below:
0xc06a00e4 <unwind_test_work>: @0xc0cc9e0c
  Compact model index: 1
  0xb2 0x81 0x01 vsp = vsp + 1032
  0xac      pop {r4, r5, r6, r7, r8, r14}
The unwind works well since the decoded uleb128 byte is also 0x81.

For vsp increments larger than 0x600,use two uleb128 bytes like below:
0xc06a00e4 <unwind_test_work>: @0xc0cc9e0c
  Compact model index: 1
  0xb2 0x81 0x02 vsp = vsp + 1544
  0xac      pop {r4, r5, r6, r7, r8, r14}
In this case,the decoded uleb128 result is 0x101(vsp=0x204+(0x101<<2)).
While the uleb128 used in code is 0x81(vsp=0x204+(0x81<<2)).
The unwind aborts at this frame since it gets incorrect vsp.

To fix this,add uleb128 decode to cover all the above case.

[PATCH 6.1 071/225] media: rcar-vin: Select correct interrupt mode for V4L2_FIELD_ALTERNATE

[Greg Kroah-Hartman]

From: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se>

[ Upstream commit e10707d5865c90d3dfe4ef589ce02ff4287fef85 ]

When adding proper support for V4L2_FIELD_ALTERNATE it was missed that
this field format should trigger an interrupt for each field, not just
for the whole frame. Fix this by marking it as progressive in the
capture setup, which will then select the correct interrupt mode.

Tested on both Gen2 and Gen3 with the result of a doubling of the frame
rate for V4L2_FIELD_ALTERNATE. From a PAL video source the frame rate is
now 50, which is expected for alternate field capture.

[PATCH 6.1 074/225] gfs2: Dont deref jdesc in evict

[Greg Kroah-Hartman]

From: Bob Peterson <rpeterso@redhat.com>

[ Upstream commit 504a10d9e46bc37b23d0a1ae2f28973c8516e636 ]

On corrupt gfs2 file systems the evict code can try to reference the
journal descriptor structure, jdesc, after it has been freed and set to
NULL. The sequence of events is:

init_journal()
...
fail_jindex:
   gfs2_jindex_free(sdp); <------frees journals, sets jdesc = NULL
      if (gfs2_holder_initialized(&ji_gh))
         gfs2_glock_dq_uninit(&ji_gh);
fail:
   iput(sdp->sd_jindex); <--references jdesc in evict_linked_inode
      evict()
         gfs2_evict_inode()
            evict_linked_inode()
               ret = gfs2_trans_begin(sdp, 0, sdp->sd_jdesc->jd_blocks);
<------references the now freed/zeroed sd_jdesc pointer.

The call to gfs2_trans_begin is done because the truncate_inode_pages
call can cause gfs2 events that require a transaction, such as removing
journaled data (jdata) blocks from the journal.

This patch fixes the problem by adding a check for sdp->sd_jdesc to
function gfs2_evict_inode. In theory, this should only happen to corrupt
gfs2 file systems, when gfs2 detects the problem, reports it, then tries
to evict all the system inodes it has read in up to that point.

[PATCH 6.1 075/225] drm/amdgpu: set gfx9 onwards APU atomics support to be true

[Greg Kroah-Hartman]

From: Yifan Zhang <yifan1.zhang@amd.com>

APUs w/ gfx9 onwards doesn't reply on PCIe atomics, rather
it is internal path w/ native atomic support. Set have_atomics_support
to true.

[PATCH 6.1 076/225] fbdev: imsttfb: Fix use after free bug in imsttfb_probe

[Greg Kroah-Hartman]

From: Zheng Wang <zyytlz.wz@163.com>

[ Upstream commit c75f5a55061091030a13fef71b9995b89bc86213 ]

A use-after-free bug may occur if init_imstt invokes framebuffer_release
and free the info ptr. The caller, imsttfb_probe didn't notice that and
still keep the ptr as private data in pdev.

If we remove the driver which will call imsttfb_remove to make cleanup,
UAF happens.

Fix it by return error code if bad case happens in init_imstt.

The debugfs_create_dir function returns ERR_PTR in case of error, and the
only correct way to check if an error occurred is 'IS_ERR' inline function.

[PATCH 6.1 082/225] nvme-pci: add quirk for missing secondary temperature thresholds

[Greg Kroah-Hartman]

From: Hristo Venev <hristo@venev.name>

[ Upstream commit bd375feeaf3408ed00e08c3bc918d6be15f691ad ]

On Kingston KC3000 and Kingston FURY Renegade (both have the same PCI
IDs) accessing temp3_{min,max} fails with an invalid field error (note
that there is no problem setting the thresholds for temp1).

This contradicts the NVM Express Base Specification 2.0b, page 292:

  The over temperature threshold and under temperature threshold
  features shall be implemented for all implemented temperature sensors
  (i.e., all Temperature Sensor fields that report a non-zero value).

Define NVME_QUIRK_NO_SECONDARY_TEMP_THRESH that disables the thresholds
for all but the composite temperature and set it for this device.

[PATCH 6.1 084/225] ASoC: dwc: limit the number of overrun messages

[Greg Kroah-Hartman]

From: Maxim Kochetkov <fido_max@inbox.ru>

[ Upstream commit ab6ecfbf40fccf74b6ec2ba7ed6dd2fc024c3af2 ]

On slow CPU (FPGA/QEMU emulated) printing overrun messages from
interrupt handler to uart console may leads to more overrun errors.
So use dev_err_ratelimited to limit the number of error messages.

[PATCH 6.1 085/225] um: harddog: fix modular build

From: Johannes Berg <johannes.berg@intel.com>

[ Upstream commit 73a23d7710331a530e972903318528b75e5a5f58 ]

Since we no longer (want to) export any libc symbols the
_user portions of any drivers need to be built into image
rather than the module. I missed this for the watchdog.
Fix the watchdog accordingly.

[PATCH 6.1 086/225] xfrm: Check if_id in inbound policy/secpath match

[Greg Kroah-Hartman]

From: Benedict Wong <benedictwong@google.com>

[ Upstream commit 8680407b6f8f5fba59e8f1d63c869abc280f04df ]

This change ensures that if configured in the policy, the if_id set in
the policy and secpath states match during the inbound policy check.
Without this, there is potential for ambiguity where entries in the
secpath differing by only the if_id could be mismatched.

Notably, this is checked in the outbound direction when resolving
templates to SAs, but not on the inbound path when matching SAs and
policies.

[PATCH 6.1 087/225] ASoC: dt-bindings: Adjust #sound-dai-cells on TIs single-DAI codecs

[Greg Kroah-Hartman]

From: Martin Povišer <povik+lin@cutebit.org>

[ Upstream commit efb2bfd7b3d210c479b9361c176d7426e5eb8663 ]

A bunch of TI's codecs have binding schemas which force #sound-dai-cells
to one despite those codecs only having a single DAI. Allow for bindings
with zero DAI cells and deprecate the former non-zero value.

These models use 2 CS35L41 amplifiers using SPI for down-facing
speakers.

alc285_fixup_speaker2_to_dac1 is needed to fix volume control of the
down-facing speakers.

Pin configs are needed to enable headset mic detection.

Note that these models lack the ACPI _DSD properties needed to
initialize the amplifiers. They can be added during boot to get working
sound out of the speakers:

[PATCH 6.1 089/225] ASoC: ssm2602: Add workaround for playback distortions

[Greg Kroah-Hartman]

From: Paweł Anikiel <pan@semihalf.com>

[ Upstream commit f63550e2b165208a2f382afcaf5551df9569e1d4 ]

Apply a workaround for what appears to be a hardware quirk.

The problem seems to happen when enabling "whole chip power" (bit D7
register R6) for the very first time after the chip receives power. If
either "output" (D4) or "DAC" (D3) aren't powered on at that time,
playback becomes very distorted later on.

This happens on the Google Chameleon v3, as well as on a ZYBO Z7-10:
https://ez.analog.com/audio/f/q-a/543726/solved-ssm2603-right-output-offset-issue/480229
I suspect this happens only when using an external MCLK signal (which
is the case for both of these boards).

Here are some experiments run on a Google Chameleon v3. These were run
in userspace using a wrapper around the i2cset utility:
ssmset() {
        i2cset -y 0 0x1a $(($1*2)) $2
}

For each of the following sequences, we apply power to the ssm2603
chip, set the configuration registers R0-R5 and R7-R8, run the selected
sequence, and check for distortions on playback.

[PATCH 6.1 090/225] media: dvb_demux: fix a bug for the continuity counter

[Greg Kroah-Hartman]

From: YongSu Yoo <yongsuyoo0215@gmail.com>

[ Upstream commit 7efb10d8dc70ea3000cc70dca53407c52488acd1 ]

In dvb_demux.c, some logics exist which compare the expected
continuity counter and the real continuity counter. If they
are not matched each other, both of the expected continuity
counter and the real continuity counter should be printed.
But there exists a bug that the expected continuity counter
is not correctly printed. The expected continuity counter is
replaced with the real countinuity counter + 1 so that
the epected continuity counter is not correclty printed.
This is wrong. This bug is fixed.

[PATCH 6.1 091/225] media: dvb-usb: az6027: fix three null-ptr-deref in az6027_i2c_xfer()

[Greg Kroah-Hartman]

From: Wei Chen <harperchen1110@gmail.com>

[ Upstream commit 858e97d7956d17a2cb56a9413468704a4d5abfe1 ]

In az6027_i2c_xfer, msg is controlled by user. When msg[i].buf is null,
commit 0ed554fd769a ("media: dvb-usb: az6027: fix null-ptr-deref in
az6027_i2c_xfer()") fix the null-ptr-deref bug when msg[i].addr is 0x99.
However, null-ptr-deref also happens when msg[i].addr is 0xd0 and 0xc0.
We add check on msg[i].len to prevent null-ptr-deref.

[PATCH 6.1 096/225] media: dvb-usb: dw2102: fix uninit-value in su3000_read_mac_address

[Greg Kroah-Hartman]

From: Wei Chen <harperchen1110@gmail.com>

[ Upstream commit a3fd1ef27aa686d871cefe207bd6168c4b0cd29e ]

In su3000_read_mac_address, if i2c_transfer fails to execute two
messages, array mac address will not be initialized. Without handling
such error, later in function dvb_usb_adapter_dvb_init, proposed_mac
is accessed before initialization.

Fix this error by returning a negative value if message execution fails.

[PATCH 6.1 097/225] media: netup_unidvb: fix irq init by register it at the end of probe

[Greg Kroah-Hartman]

From: Wei Chen <harperchen1110@gmail.com>

[ Upstream commit e6ad6233592593079db5c8fa592c298e51bc1356 ]

IRQ handler netup_spi_interrupt() takes spinlock spi->lock. The lock
is initialized in netup_spi_init(). However, irq handler is registered
before initializing the lock.

Spinlock dma->lock and i2c->lock suffer from the same problem.

Fix this by registering the irq at the end of probe.

[PATCH 6.1 098/225] media: dvb_ca_en50221: fix a size write bug

[Greg Kroah-Hartman]

From: YongSu Yoo <yongsuyoo0215@gmail.com>

[ Upstream commit a4315e5be7020aac9b24a8151caf4bb85224cd0e ]

The function of "dvb_ca_en50221_write_data" at source/drivers/media
/dvb-core/dvb_ca_en50221.c is used for two cases.
The first case is for writing APDU data in the function of
"dvb_ca_en50221_io_write" at source/drivers/media/dvb-core/
dvb_ca_en50221.c.
The second case is for writing the host link buf size on the
Command Register in the function of "dvb_ca_en50221_link_init"
at source/drivers/media/dvb-core/dvb_ca_en50221.c.
In the second case, there exists a bug like following.
In the function of the "dvb_ca_en50221_link_init",
after a TV host calculates the host link buf_size,
the TV host writes the calculated host link buf_size on the
Size Register.
Accroding to the en50221 Spec (the page 60 of
https://dvb.org/wp-content/uploads/2020/02/En50221.V1.pdf),
before this writing operation, the "SW(CMDREG_SW)" flag in the
Command Register should be set. We can see this setting operation
in the function of the "dvb_ca_en50221_link_init" like below.
...
	if ((ret = ca->pub->write_cam_control(ca->pub, slot,
CTRLIF_COMMAND, IRQEN | CMDREG_SW)) != 0)
		return ret;
...
But, after that, the real writing operation is implemented using
the function of the "dvb_ca_en50221_write_data" in the function of
"dvb_ca_en50221_link_init", and the "dvb_ca_en50221_write_data"
includes the function of "ca->pub->write_cam_control",
and the function of the "ca->pub->write_cam_control" in the
function of the "dvb_ca_en50221_wrte_data" does not include
"CMDREG_SW" flag like below.
...
	if ((status = ca->pub->write_cam_control(ca->pub, slot,
CTRLIF_COMMAND, IRQEN | CMDREG_HC)) != 0)
...
In the above source code, we can see only the "IRQEN | CMDREG_HC",
but we cannot see the "CMDREG_SW".
The "CMDREG_SW" flag which was set in the function of the
"dvb_ca_en50221_link_init" was rollbacked by the follwoing function
of the "dvb_ca_en50221_write_data".
This is a bug. and this bug causes that the calculated host link buf_size
is not properly written in the CI module.
Through this patch, we fix this bug.

[PATCH 6.1 099/225] media: ttusb-dec: fix memory leak in ttusb_dec_exit_dvb()

[Greg Kroah-Hartman]

From: Hyunwoo Kim <imv4bel@gmail.com>

[ Upstream commit 517a281338322ff8293f988771c98aaa7205e457 ]

Since dvb_frontend_detach() is not called in ttusb_dec_exit_dvb(),
which is called when the device is disconnected, dvb_frontend_free()
is not finally called.

This causes a memory leak just by repeatedly plugging and
unplugging the device.

Fix this issue by adding dvb_frontend_detach() to ttusb_dec_exit_dvb().

[PATCH 6.1 100/225] media: mn88443x: fix !CONFIG_OF error by drop of_match_ptr from ID table

[Greg Kroah-Hartman]

From: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>

[ Upstream commit ae11c0efaec32fb45130ee9886689f467232eebc ]

The driver will match mostly by DT table (even thought there is regular
ID table) so there is little benefit in of_match_ptr (this also allows
ACPI matching via PRP0001, even though it might not be relevant here).
This also fixes !CONFIG_OF error:

[PATCH 6.1 101/225] media: dvb-core: Fix use-after-free due on race condition at dvb_net

[Greg Kroah-Hartman]

From: Hyunwoo Kim <imv4bel@gmail.com>

[ Upstream commit 4172385b0c9ac366dcab78eda48c26814b87ed1a ]

A race condition may occur between the .disconnect function, which
is called when the device is disconnected, and the dvb_device_open()
function, which is called when the device node is open()ed.
This results in several types of UAFs.

The root cause of this is that you use the dvb_device_open() function,
which does not implement a conditional statement
that checks 'dvbnet->exit'.

So, add 'remove_mutex` to protect 'dvbnet->exit' and use
locked_dvb_net_open() function to check 'dvbnet->exit'.

[PATCH 6.1 102/225] media: dvb-core: Fix use-after-free due to race at dvb_register_device()

[Greg Kroah-Hartman]

From: Hyunwoo Kim <imv4bel@gmail.com>

[ Upstream commit 627bb528b086b4136315c25d6a447a98ea9448d3 ]

dvb_register_device() dynamically allocates fops with kmemdup()
to set the fops->owner.
And these fops are registered in 'file->f_ops' using replace_fops()
in the dvb_device_open() process, and kfree()d in dvb_free_device().

However, it is not common to use dynamically allocated fops instead
of 'static const' fops as an argument of replace_fops(),
and UAF may occur.
These UAFs can occur on any dvb type using dvb_register_device(),
such as dvb_dvr, dvb_demux, dvb_frontend, dvb_net, etc.

So, instead of kfree() the fops dynamically allocated in
dvb_register_device() in dvb_free_device() called during the
.disconnect() process, kfree() it collectively in exit_dvbdev()
called when the dvbdev.c module is removed.

[PATCH 6.1 103/225] media: dvb-core: Fix kernel WARNING for blocking operation in wait_event*()

[Greg Kroah-Hartman]

From: Takashi Iwai <tiwai@suse.de>

[ Upstream commit b8c75e4a1b325ea0a9433fa8834be97b5836b946 ]

Using a semaphore in the wait_event*() condition is no good idea.
It hits a kernel WARN_ON() at prepare_to_wait_event() like:
  do not call blocking ops when !TASK_RUNNING; state=1 set at
  prepare_to_wait_event+0x6d/0x690

For avoiding the potential deadlock, rewrite to an open-coded loop
instead.  Unlike the loop in wait_event*(), this uses wait_woken()
after the condition check, hence the task state stays consistent.

CVE-2023-31084 was assigned to this bug.

[PATCH 6.1 104/225] media: dvb-core: Fix use-after-free due to race condition at dvb_ca_en50221

[Greg Kroah-Hartman]

From: Hyunwoo Kim <v4bel@theori.io>

[ Upstream commit 280a8ab81733da8bc442253c700a52c4c0886ffd ]

If the device node of dvb_ca_en50221 is open() and the
device is disconnected, a UAF may occur when calling
close() on the device node.

The root cause is that wake_up() and wait_event() for
dvbdev->wait_queue are not implemented.

So implement wait_event() function in dvb_ca_en50221_release()
and add 'remove_mutex' which prevents race condition
for 'ca->exit'.

[PATCH 6.1 105/225] ASoC: SOF: debug: conditionally bump runtime_pm counter on exceptions

[Greg Kroah-Hartman]

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

[ Upstream commit 3de975862f985f1c9e225a0d13aa3d501373f7c3 ]

When a firmware IPC error happens during a pm_runtime suspend, we
ignore the error and suspend anyways. However, the code
unconditionally increases the runtime_pm counter. This results in a
confusing configuration where the code will suspend, resume but never
suspend again due to the use of pm_runtime_get_noresume().

The intent of the counter increase was to prevent entry in D3, but if
that transition to D3 is already started it cannot be stopped. In
addition, there's no point in that case in trying to prevent anything,
the firmware error is handled and the next resume will re-initialize
the firmware completely.

This patch changes the logic to prevent suspend when the device is
pm_runtime active and has a use_count > 0.

[PATCH 6.1 108/225] ASoC: SOF: pm: save io region state in case of errors in resume

[Greg Kroah-Hartman]

From: Kai Vehmanen <kai.vehmanen@linux.intel.com>

[ Upstream commit 171b53be635ac15d4feafeb33946035649b1ca14 ]

If there are failures in DSP runtime resume, the device state will not
reach active and this makes it impossible e.g. to retrieve a possible
DSP panic dump via "exception" debugfs node. If
CONFIG_SND_SOC_SOF_DEBUG_ENABLE_DEBUGFS_CACHE=y is set, the data in
cache is stale. If debugfs cache is not used, the region simply cannot
be read.

To allow debugging these scenarios, update the debugfs cache contents in
resume error handler. User-space can then later retrieve DSP panic and
other state via debugfs (requires SOF debugfs cache to be enabled in
build).

[PATCH 6.1 110/225] s390/topology: honour nr_cpu_ids when adding CPUs

[Greg Kroah-Hartman]

From: Alexander Gordeev <agordeev@linux.ibm.com>

[ Upstream commit a33239be2d38ff5a44427db1707c08787508d34a ]

When SMT thread CPUs are added to CPU masks the nr_cpu_ids
limit is not checked and could be exceeded. This leads to
a warning for example if CONFIG_DEBUG_PER_CPU_MAPS is set
and the command line parameter nr_cpus is set to 1.

[PATCH 6.1 112/225] wifi: rtl8xxxu: fix authentication timeout due to incorrect RCR value

[Greg Kroah-Hartman]

From: Yun Lu <luyun@kylinos.cn>

[ Upstream commit 20429444e653ee8242dfbf815c0c37866beb371b ]

When using rtl8192cu with rtl8xxxu driver to connect wifi, there is a
probability of failure, which shows "authentication with ... timed out".
Through debugging, it was found that the RCR register has been inexplicably
modified to an incorrect value, resulting in the nic not being able to
receive authenticated frames.

To fix this problem, add regrcr in rtl8xxxu_priv struct, and store
the RCR value every time the register is written, and use it the next
time the register need to be modified.

From: Linus Walleij <linus.walleij@linaro.org>

[ Upstream commit b0abde80620f42d1ceb3de5e4c1a49cdd5628229 ]

Like the other calls in this function virt_to_page() expects
a pointer, not an integer.

However since many architectures implement virt_to_pfn() as
a macro, this function becomes polymorphic and accepts both a
(unsigned long) and a (void *).

Fix this up with an explicit cast.

[PATCH 6.1 117/225] wifi: mac80211: consider reserved chanctx for mindef

[Greg Kroah-Hartman]

From: Johannes Berg <johannes.berg@intel.com>

[ Upstream commit b72a455a2409fd94d6d9b4eb51d659a88213243b ]

When a chanctx is reserved for a new vif and we recalculate
the minimal definition for it, we need to consider the new
interface it's being reserved for before we assign it, so it
can be used directly with the correct min channel width.

Fix the code to - optionally - consider that, and use that
option just before doing the reassignment.

Also, when considering channel context reservations, we
should only consider the one link we're currently working with.
Change the boolean argument to a link pointer to do that.

[PATCH 6.1 118/225] wifi: mac80211: recalc chanctx mindef before assigning

[Greg Kroah-Hartman]

From: Johannes Berg <johannes.berg@intel.com>

[ Upstream commit 04312de4ced4b152749614e8179f3978a20a992f ]

When we allocate a new channel context, or find an existing one
that is compatible, we currently assign it to a link before its
mindef is updated. This leads to strange situations, especially
in link switching where you switch to an 80 MHz link and expect
it to be active immediately, but the mindef is still configured
to 20 MHz while assigning.  Also, it's strange that the chandef
passed to the assign method's argument is wider than the one in
the context.

Fix this by calculating the mindef with the new link considered
before calling the driver.

In particular, this fixes an iwlwifi problem during link switch
where the firmware would assert because the (link) station that
was added for the AP is configured to transmit at a bandwidth
that's wider than the channel context that it's configured on.

[PATCH 6.1 119/225] wifi: iwlwifi: mvm: Add locking to the rate read flow

[Greg Kroah-Hartman]

From: Ariel Malamud <ariel.malamud@intel.com>

[ Upstream commit a8938bc881d2a03f9b77f19fae924fe798a01285 ]

The rs_drv_get_rate flow reads the lq_sta to return the optimal rate
for tx frames. This read flow is not protected thereby leaving
a small window, a few instructions wide, open to contention by an
asynchronous rate update. Indeed this race condition was hit and the
update occurred in the middle of the read.

Fix this by locking the lq_sta struct during read.

[PATCH 6.1 120/225] scsi: core: Decrease scsi_devices iorequest_cnt if dispatch failed

[Greg Kroah-Hartman]

From: Wenchao Hao <haowenchao2@huawei.com>

[ Upstream commit 09e797c8641f6ad435c33ae24c223351197ea29a ]

If scsi_dispatch_cmd() failed, the SCSI command was not sent to the target,
scsi_queue_rq() would return BLK_STS_RESOURCE and the related request would
be requeued. The timeout of this request would not fire, no one would
increase iodone_cnt.

The above flow would result the iodone_cnt smaller than iorequest_cnt.  So
decrease the iorequest_cnt if dispatch failed to workaround the issue.

[PATCH 6.1 121/225] wifi: b43: fix incorrect __packed annotation

[Greg Kroah-Hartman]

From: Arnd Bergmann <arnd@arndb.de>

[ Upstream commit 212457ccbd60dba34f965e4ffbe62f0e4f970538 ]

clang warns about an unpacked structure inside of a packed one:

drivers/net/wireless/broadcom/b43/b43.h:654:4: error: field data within 'struct b43_iv' is less aligned than 'union (unnamed union at /home/arnd/arm-soc/drivers/net/wireless/broadcom/b43/b43.h:651:2)' and is usually due to 'struct b43_iv' being packed, which can lead to unaligned accesses [-Werror,-Wunaligned-access]

The problem here is that the anonymous union has the default alignment
from its members, apparently because the original author mixed up the
placement of the __packed attribute by placing it next to the struct
member rather than the union definition. As the struct itself is
also marked as __packed, there is no need to mark its members, so just
move the annotation to the inner type instead.

As Michael noted, the same problem is present in b43legacy, so
change both at the same time.

[PATCH 6.1 122/225] net: wwan: t7xx: Ensure init is completed before system sleep

[Greg Kroah-Hartman]

From: Kai-Heng Feng <kai.heng.feng@canonical.com>

[ Upstream commit ab87603b251134441a67385ecc9d3371be17b7a7 ]

When the system attempts to sleep while mtk_t7xx is not ready, the driver
cannot put the device to sleep:
[   12.472918] mtk_t7xx 0000:57:00.0: [PM] Exiting suspend, modem in invalid state
[   12.472936] mtk_t7xx 0000:57:00.0: PM: pci_pm_suspend(): t7xx_pci_pm_suspend+0x0/0x20 [mtk_t7xx] returns -14
[   12.473678] mtk_t7xx 0000:57:00.0: PM: dpm_run_callback(): pci_pm_suspend+0x0/0x1b0 returns -14
[   12.473711] mtk_t7xx 0000:57:00.0: PM: failed to suspend async: error -14
[   12.764776] PM: Some devices failed to suspend, or early wake event detected

Mediatek confirmed the device can take a rather long time to complete
its initialization, so wait for up to 20 seconds until init is done.

[PATCH 6.1 125/225] nvme: do not let the user delete a ctrl before a complete initialization

[Greg Kroah-Hartman]

From: Maurizio Lombardi <mlombard@redhat.com>

[ Upstream commit 2eb94dd56a4a4e3fe286def3e2ba207804a37345 ]

If a userspace application performes a "delete_controller" command
early during the ctrl initialization, the delete operation
may race against the init code and the kernel will crash.

nvme nvme5: Connect command failed: host path error
nvme nvme5: failed to connect queue: 0 ret=880
PF: supervisor write access in kernel mode
PF: error_code(0x0002) - not-present page

 kernfs_fop_write_iter+0x124/0x1b0
 new_sync_write+0xff/0x190
 vfs_write+0x1ef/0x280

Fix the crash by checking the NVME_CTRL_STARTED_ONCE bit;
if it's not set it means that the nvme controller is still
in the process of getting initialized and the kernel
will return an -EBUSY error to userspace.
Set the NVME_CTRL_STARTED_ONCE later in the nvme_start_ctrl()
function, after the controller start operation is completed.

[PATCH 6.1 126/225] ALSA: oss: avoid missing-prototype warnings

[Greg Kroah-Hartman]

From: Arnd Bergmann <arnd@arndb.de>

[ Upstream commit 040b5a046a9e18098580d3ccd029e2318fca7859 ]

Two functions are defined and used in pcm_oss.c but also optionally
used from io.c, with an optional prototype. If CONFIG_SND_PCM_OSS_PLUGINS
is disabled, this causes a warning as the functions are not static
and have no prototype:

sound/core/oss/pcm_oss.c:1235:19: error: no previous prototype for 'snd_pcm_oss_write3' [-Werror=missing-prototypes]
sound/core/oss/pcm_oss.c:1266:19: error: no previous prototype for 'snd_pcm_oss_read3' [-Werror=missing-prototypes]

Avoid this by making the prototypes unconditional.

[PATCH 6.1 131/225] ublk: fix AB-BA lockdep warning

[Greg Kroah-Hartman]

From: Ming Lei <ming.lei@redhat.com>

[ Upstream commit ac5902f84bb546c64aea02c439c2579cbf40318f ]

When handling UBLK_IO_FETCH_REQ, ctx->uring_lock is grabbed first, then
ub->mutex is acquired.

When handling UBLK_CMD_STOP_DEV or UBLK_CMD_DEL_DEV, ub->mutex is
grabbed first, then calling io_uring_cmd_done() for canceling uring
command, in which ctx->uring_lock may be required.

Real deadlock only happens when all the above commands are issued from
same uring context, and in reality different uring contexts are often used
for handing control command and IO command.

Fix the issue by using io_uring_cmd_complete_in_task() to cancel command
in ublk_cancel_dev(ublk_cancel_queue).

[PATCH 6.1 133/225] block: Deny writable memory mapping if block is read-only

[Greg Kroah-Hartman]

From: Loic Poulain <loic.poulain@linaro.org>

[ Upstream commit 69baa3a623fd2e58624f24f2f23d46f87b817c93 ]

User should not be able to write block device if it is read-only at
block level (e.g force_ro attribute). This is ensured in the regular
fops write operation (blkdev_write_iter) but not when writing via
user mapping (mmap), allowing user to actually write a read-only
block device via a PROT_WRITE mapping.

Example: This can lead to integrity issue of eMMC boot partition
(e.g mmcblk0boot0) which is read-only by default.

To fix this issue, simply deny shared writable mapping if the block
is readonly.

Note: Block remains writable if switch to read-only is performed
after the initial mapping, but this is expected behavior according
to commit a32e236eb93e ("Partially revert "block: fail op_is_write()
requests to read-only partitions"")'.

Note that the current report, which can be triggered by the vgic_irq
kselftest, is a triple chain that includes slots_lock, but after
inverting the slots_lock/config_lock dependency, the actual problem
reported above remains.

In several places, the vgic code calls kvm_io_bus_register_dev(), which
synchronizes the srcu, while holding config_lock (#1). And the MMIO
handler takes the config_lock while holding the srcu read lock (#0).

Break dependency #1, by registering the distributor and redistributors
without holding config_lock. The ITS also uses kvm_io_bus_register_dev()
but already relies on slots_lock to serialize calls.

The distributor iodev is created on the first KVM_RUN call. Multiple
threads will race for vgic initialization, and only the first one will
see !vgic_ready() under the lock. To serialize those threads, rely on
slots_lock rather than config_lock.

Redistributors are created earlier, through KVM_DEV_ARM_VGIC_GRP_ADDR
ioctls and vCPU creation. Similarly, serialize the iodev creation with
slots_lock, and the rest with config_lock.

[PATCH 6.1 135/225] KVM: arm64: vgic: Wrap vgic_its_create() with config_lock

From: Jean-Philippe Brucker <jean-philippe@linaro.org>

[ Upstream commit 9cf2f840c439b6b23bd99f584f2917ca425ae406 ]

vgic_its_create() changes the vgic state without holding the
config_lock, which triggers a lockdep warning in vgic_v4_init():

Wrap the whole of vgic_its_create() with config_lock since, in addition
to calling vgic_v4_init(), it also modifies the global kvm->arch.vgic
state.

[PATCH 6.1 139/225] drivers: base: cacheinfo: Fix shared_cpu_map changes in event of CPU hotplug

[Greg Kroah-Hartman]

From: K Prateek Nayak <kprateek.nayak@amd.com>

[ Upstream commit 126310c9f669c9a8c875a3e5c2292299ca90225d ]

While building the shared_cpu_map, check if the cache level and cache
type matches. On certain systems that build the cache topology based on
the instance ID, there are cases where the same ID may repeat across
multiple cache levels, leading inaccurate topology.

In event of CPU offlining, the cache_shared_cpu_map_remove() does not
consider if IDs at same level are being compared. As a result, when same
IDs repeat across different cache levels, the CPU going offline is not
removed from all the shared_cpu_map.

Below is the output of cache topology of CPU8 and it's SMT sibling after
CPU8 is offlined on a dual socket 3rd Generation AMD EPYC processor
(2 x 64C/128T) running kernel release v6.3:

  # for i in /sys/devices/system/cpu/cpu8/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done
    /sys/devices/system/cpu/cpu8/cache/index0/shared_cpu_list: 8,136
    /sys/devices/system/cpu/cpu8/cache/index1/shared_cpu_list: 8,136
    /sys/devices/system/cpu/cpu8/cache/index2/shared_cpu_list: 8,136
    /sys/devices/system/cpu/cpu8/cache/index3/shared_cpu_list: 8-15,136-143

  # echo 0 > /sys/devices/system/cpu/cpu8/online

  # for i in /sys/devices/system/cpu/cpu136/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done
    /sys/devices/system/cpu/cpu136/cache/index0/shared_cpu_list: 136
    /sys/devices/system/cpu/cpu136/cache/index1/shared_cpu_list: 8,136
    /sys/devices/system/cpu/cpu136/cache/index2/shared_cpu_list: 8,136
    /sys/devices/system/cpu/cpu136/cache/index3/shared_cpu_list: 9-15,136-143

CPU8 is removed from index0 (L1i) but remains in the shared_cpu_list of
index1 (L1d) and index2 (L2). Since L1i, L1d, and L2 are shared by the
SMT siblings, and they have the same cache instance ID, CPU 2 is only
removed from the first index with matching ID which is index1 (L1i) in
this case. With this fix, the results are as expected when performing
the same experiment on the same system:

  # for i in /sys/devices/system/cpu/cpu8/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done
    /sys/devices/system/cpu/cpu8/cache/index0/shared_cpu_list: 8,136
    /sys/devices/system/cpu/cpu8/cache/index1/shared_cpu_list: 8,136
    /sys/devices/system/cpu/cpu8/cache/index2/shared_cpu_list: 8,136
    /sys/devices/system/cpu/cpu8/cache/index3/shared_cpu_list: 8-15,136-143

  # echo 0 > /sys/devices/system/cpu/cpu8/online

  # for i in /sys/devices/system/cpu/cpu136/cache/index*/shared_cpu_list; do echo -n "$i: "; cat $i; done
    /sys/devices/system/cpu/cpu136/cache/index0/shared_cpu_list: 136
    /sys/devices/system/cpu/cpu136/cache/index1/shared_cpu_list: 136
    /sys/devices/system/cpu/cpu136/cache/index2/shared_cpu_list: 136
    /sys/devices/system/cpu/cpu136/cache/index3/shared_cpu_list: 9-15,136-143

When rebuilding topology, the same problem appears as
cache_shared_cpu_map_setup() implements a similar logic. Consider the
same 3rd Generation EPYC processor: CPUs in Core 1, that share the L1
and L2 caches, have L1 and L2 instance ID as 1. For all the CPUs on
the second chiplet, the L3 ID is also 1 leading to grouping on CPUs from
Core 1 (1, 17) and the entire second chiplet (8-15, 24-31) as CPUs
sharing one cache domain. This went undetected since x86 processors
depended on arch specific populate_cache_leaves() method to repopulate
the shared_cpus_map when CPU came back online until kernel release
v6.3-rc5.

[PATCH 6.1 140/225] media: uvcvideo: Dont expose unsupported formats to userspace

[Greg Kroah-Hartman]

From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

[ Upstream commit 81f3affa19d6ab0c32aef46b053838219eef7e71 ]

When the uvcvideo driver encounters a format descriptor with an unknown
format GUID, it creates a corresponding struct uvc_format instance with
the fcc field set to 0. Since commit 50459f103edf ("media: uvcvideo:
Remove format descriptions"), the driver relies on the V4L2 core to
provide the format description string, which the V4L2 core can't do
without a valid 4CC. This triggers a WARN_ON.

As a format with a zero 4CC can't be selected, it is unusable for
applications. Ignore the format completely without creating a uvc_format
instance, which fixes the warning.

[PATCH 6.1 141/225] iio: accel: st_accel: Fix invalid mount_matrix on devices without ACPI _ONT method

[Greg Kroah-Hartman]

From: Hans de Goede <hdegoede@redhat.com>

commit 79b8ded9d9c595db9bd5b2f62f5f738b36de1e22 upstream.

When apply_acpi_orientation() fails, st_accel_common_probe() will fall back
to iio_read_mount_matrix(), which checks for a mount-matrix device property
and if that is not set falls back to the identity matrix.

But when a sensor has no ACPI companion fwnode, or when the ACPI fwnode
does not have a "_ONT" method apply_acpi_orientation() was returning 0,
causing iio_read_mount_matrix() to never get called resulting in an
invalid mount_matrix:

[root@fedora ~]# cat /sys/bus/iio/devices/iio\:device0/mount_matrix
(null), (null), (null); (null), (null), (null); (null), (null), (null)

Fix this by making apply_acpi_orientation() always return an error when
it did not set the mount_matrix.

[PATCH 6.1 142/225] iio: adc: mxs-lradc: fix the order of two cleanup operations

[Greg Kroah-Hartman]

From: Jiakai Luo <jkluo@hust.edu.cn>

commit 27b2ed5b6d53cd62fc61c3f259ae52f5cac23b66 upstream.

Smatch reports:
drivers/iio/adc/mxs-lradc-adc.c:766 mxs_lradc_adc_probe() warn:
missing unwind goto?

the order of three init operation:
1.mxs_lradc_adc_trigger_init
2.iio_triggered_buffer_setup
3.mxs_lradc_adc_hw_init

thus, the order of three cleanup operation should be:
1.mxs_lradc_adc_hw_stop
2.iio_triggered_buffer_cleanup
3.mxs_lradc_adc_trigger_remove

we exchange the order of two cleanup operations,
introducing the following differences:
1.if mxs_lradc_adc_trigger_init fails, returns directly;
2.if trigger_init succeeds but iio_triggered_buffer_setup fails,
goto err_trig and remove the trigger.

In addition, we also reorder the unwind that goes on in the
remove() callback to match the new ordering.

[PATCH 6.1 144/225] HID: wacom: avoid integer overflow in wacom_intuos_inout()

[Greg Kroah-Hartman]

From: Nikita Zhandarovich <n.zhandarovich@fintech.ru>

commit bd249b91977b768ea02bf84d04625d2690ad2b98 upstream.

If high bit is set to 1 in ((data[3] & 0x0f << 28), after all arithmetic
operations and integer promotions are done, high bits in
wacom->serial[idx] will be filled with 1s as well.
Avoid this, albeit unlikely, issue by specifying left operand's __u64
type for the right operand.

Found by Linux Verification Center (linuxtesting.org) with static
analysis tool SVACE.

[PATCH 6.1 145/225] iio: imu: inv_icm42600: fix timestamp reset

[Greg Kroah-Hartman]

From: Jean-Baptiste Maneyrol <jean-baptiste.maneyrol@tdk.com>

commit bbaae0c79ebd49f61ad942a8bf9e12bfc7f821bb upstream.

Timestamp reset is not done in the correct place. It must be done
before enabling buffer. The reason is that interrupt timestamping
is always happening when the chip is on, even if the
corresponding sensor is off. When the sensor restarts, timestamp
is wrong if you don't do a reset first.

[PATCH 6.1 149/225] iio: adc: ad_sigma_delta: Fix IRQ issue by setting IRQ_DISABLE_UNLAZY flag

[Greg Kroah-Hartman]

From: Masahiro Honda <honda@mechatrax.com>

commit 626d312028bec44209d0ecd5beaa9b1aa8945f7d upstream.

The Sigma-Delta ADCs supported by this driver can use SDO as an interrupt
line to indicate the completion of a conversion. However, some devices
cannot properly detect the completion of a conversion by an interrupt.
This is for the reason mentioned in the following commit.

commit e9849777d0e2 ("genirq: Add flag to force mask in
                      disable_irq[_nosync]()")

A read operation is performed by an extra interrupt before the completion
of a conversion. At this time, the value read from the ADC data register
is the same as the previous conversion result. This patch fixes the issue
by setting IRQ_DISABLE_UNLAZY flag.

[PATCH 6.1 150/225] iio: dac: mcp4725: Fix i2c_master_send() return value handling

[Greg Kroah-Hartman]

From: Marek Vasut <marex@denx.de>

commit 09d3bec7009186bdba77039df01e5834788b3f95 upstream.

The i2c_master_send() returns number of sent bytes on success,
or negative on error. The suspend/resume callbacks expect zero
on success and non-zero on error. Adapt the return value of the
i2c_master_send() to the expectation of the suspend and resume
callbacks, including proper validation of the return value.

[PATCH 6.1 151/225] iio: addac: ad74413: fix resistance input processing

[Greg Kroah-Hartman]

From: Rasmus Villemoes <linux@rasmusvillemoes.dk>

commit 24febc99ca725dcf42d57168a2f4e8a75a5ade92 upstream.

On success, ad74413r_get_single_adc_result() returns IIO_VAL_INT aka
1. So currently, the IIO_CHAN_INFO_PROCESSED case is effectively
equivalent to the IIO_CHAN_INFO_RAW case, and we never call
ad74413r_adc_to_resistance_result() to convert the adc measurement to
ohms.

Check ret for being negative rather than non-zero.

[PATCH 6.1 152/225] iio: adc: ad7192: Change "shorted" channels to differential

[Greg Kroah-Hartman]

From: Paul Cercueil <paul@crapouillou.net>

commit e55245d115bb9054cb72cdd5dda5660f4484873a upstream.

The AD7192 provides a specific channel configuration where both negative
and positive inputs are connected to AIN2. This was represented in the
ad7192 driver as a IIO channel with .channel = 2 and .extended_name set
to "shorted".

The problem with this approach, is that the driver provided two IIO
channels with the identifier .channel = 2; one "shorted" and the other
not. This goes against the IIO ABI, as a channel identifier should be
unique.

Address this issue by changing "shorted" channels to being differential
instead, with channel 2 vs. itself, as we're actually measuring AIN2 vs.
itself.

Note that the fix tag is for the commit that moved the driver out of
staging. The bug existed before that, but backporting would become very
complex further down and unlikely to happen.

[PATCH 6.1 154/225] iio: dac: build ad5758 driver when AD5758 is selected

[Greg Kroah-Hartman]

From: Lukas Bulwahn <lukas.bulwahn@gmail.com>

commit a146eccb68be161ae9eab5f3f68bb0ed7c0fbaa8 upstream.

Commit 28d1a7ac2a0d ("iio: dac: Add AD5758 support") adds the config AD5758
and the corresponding driver ad5758.c. In the Makefile, the ad5758 driver
is however included when AD5755 is selected, not when AD5758 is selected.

Probably, this was simply a mistake that happened by copy-and-paste and
forgetting to adjust the actual line. Surprisingly, no one has ever noticed
that this driver is actually only included when AD5755 is selected and that
the config AD5758 has actually no effect on the build.

[PATCH 6.1 157/225] usb: cdns3: fix NCM gadget RX speed 20x slow than expection at iMX8QM

[Greg Kroah-Hartman]

From: Frank Li <Frank.Li@nxp.com>

commit dbe678f6192f27879ac9ff6bc7a1036aad85aae9 upstream.

At iMX8QM platform, enable NCM gadget and run 'iperf3 -s'.
At host, run 'iperf3 -V -c fe80::6863:98ff:feef:3e0%enxc6e147509498'

[  5]   0.00-1.00   sec  1.55 MBytes  13.0 Mbits/sec   90   4.18 KBytes
[  5]   1.00-2.00   sec  1.44 MBytes  12.0 Mbits/sec   75   4.18 KBytes
[  5]   2.00-3.00   sec  1.48 MBytes  12.4 Mbits/sec   75   4.18 KBytes

Expected speed should be bigger than 300Mbits/sec.

The root cause of this performance drop was found to be data corruption
happening at 4K borders in some Ethernet packets, leading to TCP
checksum errors. This corruption occurs from the position
(4K - (address & 0x7F)) to 4K. The u_ether function's allocation of
skb_buff reserves 64B, meaning all RX addresses resemble 0xXXXX0040.

Force trb_burst_size to 16 can fix this problem.

[PATCH 6.1 158/225] usb: gadget: f_fs: Add unbind event before functionfs_unbind

[Greg Kroah-Hartman]

From: Uttkarsh Aggarwal <quic_uaggarwa@quicinc.com>

commit efb6b535207395a5c7317993602e2503ca8cb4b3 upstream.

While exercising the unbind path, with the current implementation
the functionfs_unbind would be calling which waits for the ffs->mutex
to be available, however within the same time ffs_ep0_read is invoked
& if no setup packets are pending, it will invoke function
wait_event_interruptible_exclusive_locked_irq which by definition waits
for the ev.count to be increased inside the same mutex for which
functionfs_unbind is waiting.
This creates deadlock situation because the functionfs_unbind won't
get the lock until ev.count is increased which can only happen if
the caller ffs_func_unbind can proceed further.

Following is the illustration:

	CPU1				CPU2

ffs_func_unbind()		ffs_ep0_read()
				mutex_lock(ffs->mutex)
				wait_event(ffs->ev.count)
functionfs_unbind()
  mutex_lock(ffs->mutex)
  mutex_unlock(ffs->mutex)

ffs_event_add()

<deadlock>

Fix this by moving the event unbind before functionfs_unbind
to ensure the ev.count is incrased properly.

[PATCH 6.1 160/225] misc: fastrpc: return -EPIPE to invocations on device removal

[Greg Kroah-Hartman]

From: Richard Acayan <mailingradian@gmail.com>

commit b6a062853ddf6b4f653af2d8b75ba45bb9a036ad upstream.

The return value is initialized as -1, or -EPERM. The completion of an
invocation implies that the return value is set appropriately, but
"Permission denied" does not accurately describe the outcome of the
invocation. Set the invocation's return value to a more appropriate
"Broken pipe", as the cleanup breaks the driver's connection with rpmsg.

[PATCH 6.1 161/225] misc: fastrpc: reject new invocations during device removal

[Greg Kroah-Hartman]

From: Richard Acayan <mailingradian@gmail.com>

commit 46248400d81e2aa0b65cd659d6f40188192a58b6 upstream.

The channel's rpmsg object allows new invocations to be made. After old
invocations are already interrupted, the driver shouldn't try to invoke
anymore. Invalidating the rpmsg at the end of the driver removal
function makes it easy to cause a race condition in userspace. Even
closing a file descriptor before the driver finishes its cleanup can
cause an invocation via fastrpc_release_current_dsp_process() and
subsequent timeout.

Invalidate the channel before the invocations are interrupted to make
sure that no invocations can be created to hang after the device closes.

[PATCH 6.1 162/225] scsi: stex: Fix gcc 13 warnings

[Greg Kroah-Hartman]

From: Bart Van Assche <bvanassche@acm.org>

commit 6d074ce231772c66e648a61f6bd2245e7129d1f5 upstream.

gcc 13 may assign another type to enumeration constants than gcc 12. Split
the large enum at the top of source file stex.c such that the type of the
constants used in time expressions is changed back to the same type chosen
by gcc 12. This patch suppresses compiler warnings like this one:

[PATCH 6.1 163/225] ata: libata-scsi: Use correct device no in ata_find_dev()

[Greg Kroah-Hartman]

From: Damien Le Moal <dlemoal@kernel.org>

commit 7f875850f20a42f488840c9df7af91ef7db2d576 upstream.

For devices not attached to a port multiplier and managed directly by
libata, the device number passed to ata_find_dev() must always be lower
than the maximum number of devices returned by ata_link_max_devices().
That is 1 for SATA devices or 2 for an IDE link with master+slave
devices. This device number is the SCSI device ID which matches these
constraints as the IDs are generated per port and so never exceed the
maximum number of devices for the link being used.

However, for libsas managed devices, SCSI device IDs are assigned per
struct scsi_host, leading to device IDs for SATA devices that can be
well in excess of libata per-link maximum number of devices. This
results in ata_find_dev() to always return NULL for libsas managed
devices except for the first device of the target scsi_host with ID
(device number) equal to 0. This issue is visible by executing the
hdparm utility, which fails. E.g.:

hdparm -i /dev/sdX
/dev/sdX:
  HDIO_GET_IDENTITY failed: No message of desired type

Fix this by rewriting ata_find_dev() to ignore the device number for
non-PMP attached devices with a link with at most 1 device, that is SATA
devices. For these, the device number 0 is always used to
return the correct pointer to the struct ata_device of the port link.
This change excludes IDE master/slave setups (maximum number of devices
per link is 2) and port-multiplier attached devices. Also, to be
consistant with the fact that SCSI device IDs and channel numbers used
as device numbers are both unsigned int, change the devno argument of
ata_find_dev() to unsigned int.

[PATCH 6.1 165/225] drm/amd/pm: reverse mclk and fclk clocks levels for SMU v13.0.4

[Greg Kroah-Hartman]

From: Tim Huang <Tim.Huang@amd.com>

commit 6a07826f2057b5fa1c479ba56460195882464270 upstream.

This patch reverses the DPM clocks levels output of pp_dpm_mclk
and pp_dpm_fclk.

On dGPUs and older APUs we expose the levels from lowest clocks
to highest clocks. But for some APUs, the clocks levels that from
the DFPstateTable are given the reversed orders by PMFW. Like the
memory DPM clocks that are exposed by pp_dpm_mclk.

It's not intuitive that they are reversed on these APUs. All tools
and software that talks to the driver then has to know different ways
to interpret the data depending on the asic.

So we need to reverse them to expose the clocks levels from the
driver consistently.

[PATCH 6.1 169/225] drm/amd/pm: reverse mclk and fclk clocks levels for yellow carp

[Greg Kroah-Hartman]

From: Tim Huang <Tim.Huang@amd.com>

commit f1373a97a41f429e0095d4be388092ffa3c1a157 upstream.

This patch reverses the DPM clocks levels output of pp_dpm_mclk
and pp_dpm_fclk.

On dGPUs and older APUs we expose the levels from lowest clocks
to highest clocks. But for some APUs, the clocks levels that from
the DFPstateTable are given the reversed orders by PMFW. Like the
memory DPM clocks that are exposed by pp_dpm_mclk.

It's not intuitive that they are reversed on these APUs. All tools
and software that talks to the driver then has to know different ways
to interpret the data depending on the asic.

So we need to reverse them to expose the clocks levels from the
driver consistently.

[PATCH 6.1 171/225] x86/mtrr: Revert 90b926e68f50 ("x86/pat: Fix pat_x_mtrr_type() for MTRR disabled case")

[Greg Kroah-Hartman]

From: Juergen Gross <jgross@suse.com>

commit f9f57da2c2d119dbf109e3f6e1ceab7659294046 upstream.

Commit

  90b926e68f50 ("x86/pat: Fix pat_x_mtrr_type() for MTRR disabled case")

broke the use case of running Xen dom0 kernels on machines with an
external disk enclosure attached via USB, see Link tag.

What this commit was originally fixing - SEV-SNP guests on Hyper-V - is
a more specialized situation which has other issues at the moment anyway
so reverting this now and addressing the issue properly later is the
prudent thing to do.

So revert it in time for the 6.2 proper release.

[PATCH 6.1 172/225] mmc: vub300: fix invalid response handling

[Greg Kroah-Hartman]

From: Deren Wu <deren.wu@mediatek.com>

commit a99d21cefd351c8aaa20b83a3c942340e5789d45 upstream.

We may get an empty response with zero length at the beginning of
the driver start and get following UBSAN error. Since there is no
content(SDRT_NONE) for the response, just return and skip the response
handling to avoid this problem.

Test pass : SDIO wifi throughput test with this patch

[PATCH 6.1 173/225] mmc: pwrseq: sd8787: Fix WILC CHIP_EN and RESETN toggling order

[Greg Kroah-Hartman]

From: Marek Vasut <marex@denx.de>

commit 0b5d5c436a5c572a45f976cfd34a6741e143e5d9 upstream.

Chapter "5.3 Power-Up/Down Sequence" of WILC1000 [1] and WILC3000 [2]
states that CHIP_EN must be pulled HIGH first, RESETN second. Fix the
order of these signals in the driver.

Use the mmc_pwrseq_ops as driver data as the delay between signals is
specific to SDIO card type anyway.

[PATCH 6.1 174/225] tty: serial: fsl_lpuart: use UARTCTRL_TXINV to send break instead of UARTCTRL_SBK

[Greg Kroah-Hartman]

From: Sherry Sun <sherry.sun@nxp.com>

commit 2474e05467c00f7d51af3039b664de6886325257 upstream.

LPUART IP now has two known bugs, one is that CTS has higher priority
than the break signal, which causes the break signal sending through
UARTCTRL_SBK may impacted by the CTS input if the HW flow control is
enabled. It exists on all platforms we support in this driver.
So we add a workaround patch for this issue: commit c4c81db5cf8b
("tty: serial: fsl_lpuart: disable the CTS when send break signal").

Another IP bug is i.MX8QM LPUART may have an additional break character
being sent after SBK was cleared. It may need to add some delay between
clearing SBK and re-enabling CTS to ensure that the SBK latch are
completely cleared.

But we found that during the delay period before CTS is enabled, there
is still a risk that Bluetooth data in TX FIFO may be sent out during
this period because of break off and CTS disabled(even if BT sets CTS
line deasserted, data is still sent to BT).

Due to this risk, we have to drop the CTS-disabling workaround for SBK
bugs, use TXINV seems to be a better way to replace SBK feature and
avoid above risk. Also need to disable the transmitter to prevent any
data from being sent out during break, then invert the TX line to send
break. Then disable the TXINV when turn off break and re-enable
transmitter.

We can check if i overflows to solve the problem. However, this doesn't make
much sense, since i == 1 and num_pages == 1 doesn't execute the body of the loop.
In addition, i < num_pages can also ensure that buf->pages[i] will not cross
the boundary. Unfortunately, this doesn't help with the problem observed here:
gcc still complains.

To fix this add a compile-time condition for the extent buffer page
array size limit, which would eventually lead to eliminating the whole
for loop.

[PATCH 6.1 176/225] phy: qcom-qmp-combo: fix init-count imbalance

[Greg Kroah-Hartman]

From: Johan Hovold <johan+linaro@kernel.org>

commit 9bf03a0cbd80a256bc1e1c4bcc80bc2b06b8b2b9 upstream.

The init counter is not decremented on initialisation errors, which
prevents retrying initialisation and can lead to the runtime suspend
callback attempting to disable resources that have never been enabled.

Add the missing decrement on initialisation errors so that the counter
reflects the state of the device.

[PATCH 6.1 178/225] block: fix revalidate performance regression

[Greg Kroah-Hartman]

From: Damien Le Moal <dlemoal@kernel.org>

commit 47fe1c3064c6bc1bfa3c032ff78e603e5dd6e5bc upstream.

The scsi driver function sd_read_block_characteristics() always calls
disk_set_zoned() to a disk zoned model correctly, in case the device
model changed. This is done even for regular disks to set the zoned
model to BLK_ZONED_NONE and free any zone related resources if the drive
previously was zoned.

This behavior significantly impact the time it takes to revalidate disks
on a large system as the call to disk_clear_zone_settings() done from
disk_set_zoned() for the BLK_ZONED_NONE case results in the device
request queued to be frozen, even if there are no zone resources to
free.

Avoid this overhead for non-zoned devices by not calling
disk_clear_zone_settings() in disk_set_zoned() if the device model
was already set to BLK_ZONED_NONE, which is always the case for regular
devices.

[PATCH 6.1 179/225] powerpc/iommu: Limit number of TCEs to 512 for H_STUFF_TCE hcall

[Greg Kroah-Hartman]

From: Gaurav Batra <gbatra@linux.vnet.ibm.com>

commit 9d2ccf00bddc268045e3d65a8108d61ada0e4b4e upstream.

Currently in tce_freemulti_pSeriesLP() there is no limit on how many
TCEs are passed to the H_STUFF_TCE hcall. This has not caused an issue
until now, but newer firmware releases have started enforcing a limit of
512 TCEs per call.

The limit is correct per the specification (PAPR v2.12 § 14.5.4.2.3).

The code has been in it's current form since it was initially merged.

[PATCH 6.1 180/225] iommu/amd: Fix domain flush size when syncing iotlb

[Greg Kroah-Hartman]

From: Jon Pan-Doh <pandoh@google.com>

commit 2212fc2acf3f6ee690ea36506fb882a19d1bfcab upstream.

When running on an AMD vIOMMU, we observed multiple invalidations (of
decreasing power of 2 aligned sizes) when unmapping a single page.

Domain flush takes gather bounds (end-start) as size param. However,
gather->end is defined as the last inclusive address (start + size - 1).
This leads to an off by 1 error.

With this patch, verified that 1 invalidation occurs when unmapping a
single page.

[PATCH 6.1 181/225] tpm, tpm_tis: correct tpm_tis_flags enumeration values

From: Lino Sanfilippo <l.sanfilippo@kunbus.com>

commit 4ecd704a4c51fd95973fcc3a60444e0e24eb9439 upstream.

With commit 858e8b792d06 ("tpm, tpm_tis: Avoid cache incoherency in test

tpm_tis_data->flags.

However these functions expect bit numbers, while the flags are defined
as bit masks in enum tpm_tis_flag.

Fix this inconsistency by using numbers instead of masks also for the
flags in the enum.

[PATCH 6.1 182/225] riscv: perf: Fix callchain parse error with kernel tracepoint events

[Greg Kroah-Hartman]

From: Ism Hong <ism.hong@gmail.com>

commit 9a7e8ec0d4cc64870ea449b4fce5779b77496cbb upstream.

For RISC-V, when tracing with tracepoint events, the IP and status are
set to 0, preventing the perf code parsing the callchain and resolving
the symbols correctly.

 ./ply 'tracepoint:kmem/kmem_cache_alloc { @[stack]=count(); }'
 @:
 { <STACKID4294967282> }: 1

The fix is to implement perf_arch_fetch_caller_regs for riscv, which
fills several necessary registers used for callchain unwinding,
including epc, sp, s0 and status. It's similar to commit b3eac0265bf6
("arm: perf: Fix callchain parse error with kernel tracepoint events")
and commit 5b09a094f2fb ("arm64: perf: Fix callchain parse error with
kernel tracepoint events").

With this patch, callchain can be parsed correctly as:

 ./ply 'tracepoint:kmem/kmem_cache_alloc { @[stack]=count(); }'

commit 42c4e97e06a839b07d834f640a10911ad84ec8b3 upstream.

The Linux Kernel currently only requires make v3.82 while the grouped
target functionality requires make v4.3.  Removed the grouped target
introduced in 4ce1f694eb5d ("selinux: ensure av_permissions.h is
built when needed") as well as the multiple header file targets in
the make rule.  This effectively reverts the problem commit.

We will revisit this change when make >= 4.3 is required by the rest
of the kernel.

[PATCH 6.1 185/225] mtdchar: mark bits of ioctl handler noinline

From: Arnd Bergmann <arnd@arndb.de>

commit 0ea923f443350c8c5cca6eef5b748d52b903f46c upstream.

The addition of the mtdchar_read_ioctl() function caused the stack usage
of mtdchar_ioctl() to grow beyond the warning limit on 32-bit architectures
with gcc-13:

drivers/mtd/mtdchar.c:1229:1: error: the frame size of 1488 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]

Mark both the read and write portions as noinline_for_stack to ensure
they don't get inlined and use separate stack slots to reduce the
maximum usage, both in the mtdchar_ioctl() and combined with any
of its callees.

[PATCH 6.1 186/225] tracing/timerlat: Always wakeup the timerlat thread

[Greg Kroah-Hartman]

From: Daniel Bristot de Oliveira <bristot@kernel.org>

commit 632478a05821bc1c9b55c3a1dd0fb1be7bfa1acc upstream.

While testing rtla timerlat auto analysis, I reach a condition where
the interface was not receiving tracing data. I was able to manually
reproduce the problem with these steps:

  # echo 0 > tracing_on                 # disable trace
  # echo 1 > osnoise/stop_tracing_us    # stop trace if timerlat irq > 1 us
  # echo timerlat > current_tracer      # enable timerlat tracer
  # sleep 1                             # wait... that is the time when rtla
                                        # apply configs like prio or cgroup
  # echo 1 > tracing_on                 # start tracing
  # cat trace
  # tracer: timerlat
  #
  #                                _-----=> irqs-off
  #                               / _----=> need-resched
  #                              | / _---=> hardirq/softirq
  #                              || / _--=> preempt-depth
  #                              ||| / _-=> migrate-disable
  #                              |||| /     delay
  #                              |||||            ACTIVATION
  #           TASK-PID      CPU# |||||   TIMESTAMP   ID            CONTEXT                 LATENCY
  #              | |         |   |||||      |         |                  |                       |
        NOTHING!

Then, trying to enable tracing again with echo 1 > tracing_on resulted
in no change: the trace was still not tracing.

This problem happens because the timerlat IRQ hits the stop tracing
condition while tracing is off, and do not wake up the timerlat thread,
so the timerlat threads are kept sleeping forever, resulting in no
trace, even after re-enabling the tracer.

Avoid this condition by always waking up the threads, even after stopping
tracing, allowing the tracer to return to its normal operating after
a new tracing on.

[PATCH 6.1 187/225] tracing/histograms: Allow variables to have some modifiers

[Greg Kroah-Hartman]

From: Steven Rostedt (Google) <rostedt@goodmis.org>

commit e30fbc618e97b38dbb49f1d44dcd0778d3f23b8c upstream.

Modifiers are used to change the behavior of keys. For instance, they
can grouped into buckets, converted to syscall names (from the syscall
identifier), show task->comm of the current pid, be an array of longs
that represent a stacktrace, and more.

It was found that nothing stopped a value from taking a modifier. As
values are simple counters. If this happened, it would call code that
was not expecting a modifier and crash the kernel. This was fixed by
having the ___create_val_field() function test if a modifier was present
and fail if one was. This fixed the crash.

Now there's a problem with variables. Variables are used to pass fields
from one event to another. Variables are allowed to have some modifiers,
as the processing may need to happen at the time of the event (like
stacktraces and comm names of the current pid). The issue is that it too
uses __create_val_field(). Now that fails on modifiers, variables can no
longer use them (this is a regression).

As not all modifiers are for variables, have them use a separate check.

[PATCH 6.1 188/225] tracing/probe: trace_probe_primary_from_call(): checked list_first_entry

[Greg Kroah-Hartman]

From: Pietro Borrello <borrello@diag.uniroma1.it>

commit 81d0fa4cb4fc0e1a49c2b22f92c43d9fe972ebcf upstream.

All callers of trace_probe_primary_from_call() check the return
value to be non NULL. However, the function returns
list_first_entry(&tpe->probes, ...) which can never be NULL.
Additionally, it does not check for the list being possibly empty,
possibly causing a type confusion on empty lists.
Use list_first_entry_or_null() which solves both problems.

[PATCH 6.1 189/225] selftests: mptcp: connect: skip if MPTCP is not supported

[Greg Kroah-Hartman]

From: Matthieu Baerts <matthieu.baerts@tessares.net>

commit d83013bdf90a7994a474b0e650a7fc94b0d4ded6 upstream.

Selftests are supposed to run on any kernels, including the old ones not
supporting MPTCP.

A new check is then added to make sure MPTCP is supported. If not, the
test stops and is marked as "skipped". Note that this check can also
mark the test as failed if 'SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES' env
var is set to 1: by doing that, we can make sure a test is not being
skipped by mistake.

A new shared file is added here to be able to re-used the same check in
the different selftests we have.

[PATCH 6.1 194/225] mptcp: fix connect timeout handling

[Greg Kroah-Hartman]

From: Paolo Abeni <pabeni@redhat.com>

commit 786fc12457268cc9b555dde6c22ae7300d4b40e1 upstream.

Ondrej reported a functional issue WRT timeout handling on connect
with a nice reproducer.

The problem is that the current mptcp connect waits for both the
MPTCP socket level timeout, and the first subflow socket timeout.
The latter is not influenced/touched by the exposed setsockopt().

Overall the above makes the SO_SNDTIMEO a no-op on connect.

Since mptcp_connect is invoked via inet_stream_connect and the
latter properly handle the MPTCP level timeout, we can address the
issue making the nested subflow level connect always unblocking.

This also allow simplifying a bit the code, dropping an ugly hack
to handle the fastopen and custom proto_ops connect.

The issues predates the blamed commit below, but the current resolution
requires the infrastructure introduced there.

[PATCH 6.1 195/225] mptcp: fix active subflow finalization

[Greg Kroah-Hartman]

From: Paolo Abeni <pabeni@redhat.com>

commit 55b47ca7d80814ceb63d64e032e96cd6777811e5 upstream.

Active subflow are inserted into the connection list at creation time.
When the MPJ handshake completes successfully, a new subflow creation
netlink event is generated correctly, but the current code wrongly
avoid initializing a couple of subflow data.

The above will cause misbehavior on a few exceptional events: unneeded
mptcp-level retransmission on msk-level sequence wrap-around and infinite
mapping fallback even when a MPJ socket is present.

Address the issue factoring out the needed initialization in a new helper
and invoking the latter from __mptcp_finish_join() time for passive
subflow and from mptcp_finish_join() for active ones.

Fixes: 0530020a7c8f ("mptcp: track and update contiguous data status")

[PATCH 6.1 196/225] ext4: add EA_INODE checking to ext4_iget()

[Greg Kroah-Hartman]

From: Theodore Ts'o <tytso@mit.edu>

commit b3e6bcb94590dea45396b9481e47b809b1be4afa upstream.

Add a new flag, EXT4_IGET_EA_INODE which indicates whether the inode
is expected to have the EA_INODE flag or not.  If the flag is not
set/clear as expected, then fail the iget() operation and mark the
file system as corrupted.

This commit also makes the ext4_iget() always perform the
is_bad_inode() check even when the inode is already inode cache.  This
allows us to remove the is_bad_inode() check from the callers of
ext4_iget() in the ea_inode code.

[PATCH 6.1 197/225] ext4: set lockdep subclass for the ea_inode in ext4_xattr_inode_cache_find()

[Greg Kroah-Hartman]

From: Theodore Ts'o <tytso@mit.edu>

commit b928dfdcb27d8fa59917b794cfba53052a2f050f upstream.

If the ea_inode has been pushed out of the inode cache while there is
still a reference in the mb_cache, the lockdep subclass will not be
set on the inode, which can lead to some lockdep false positives.

commit 2bc7e7c1a3bc9bd0cbf0f71006f6fe7ef24a00c2 upstream.

An ea_inode stores the value of an extended attribute; it can not have
extended attributes itself, or this will cause recursive nightmares.
Add a check in ext4_iget() to make sure this is the case.

[PATCH 6.1 199/225] ext4: add lockdep annotations for i_data_sem for ea_inodes

From: Theodore Ts'o <tytso@mit.edu>

commit aff3bea95388299eec63440389b4545c8041b357 upstream.

Treat i_data_sem for ea_inodes as being in their own lockdep class to
avoid lockdep complaints about ext4_setattr's use of inode_lock() on
normal inodes potentially causing lock ordering with i_data_sem on
ea_inodes in ext4_xattr_inode_write().  However, ea_inodes will be
operated on by ext4_setattr(), so this isn't a problem.

[PATCH 6.1 202/225] serial: cpm_uart: Fix a COMPILE_TEST dependency

[Greg Kroah-Hartman]

From: Herve Codina <herve.codina@bootlin.com>

commit 7183c37fd53eee1e795206e625da12a5d7ec1e1a upstream.

In a COMPILE_TEST configuration, the cpm_uart driver uses symbols from
the cpm_uart_cpm2.c file. This file is compiled only when CONFIG_CPM2 is
set.

Without this dependency, the linker fails with some missing symbols for
COMPILE_TEST configuration that needs SERIAL_CPM without enabling CPM2.

This lead to:
  depends on CPM2 || CPM1 || (PPC32 && CPM2 && COMPILE_TEST)

This dependency does not make sense anymore and can be simplified
removing all the COMPILE_TEST part.

[PATCH 6.1 203/225] powerpc/xmon: Use KSYM_NAME_LEN in array size

[Greg Kroah-Hartman]

From: Maninder Singh <maninder1.s@samsung.com>

commit 719dfd5925e186e09a2a6f23016936ac436f3d78 upstream.

kallsyms_lookup() which in turn calls kallsyms_lookup_buildid() writes
to index "KSYM_NAME_LEN - 1".

Thus the array passed as namebuf to kallsyms_lookup() should be
KSYM_NAME_LEN in size.

In xmon.c the array was defined to be "128" bytes directly, without
using KSYM_NAME_LEN. Commit b8a94bfb3395 ("kallsyms: increase maximum
kernel symbol length to 512") changed the value to 512, but missed
updating the xmon code.

Fixes: b8a94bfb3395 ("kallsyms: increase maximum kernel symbol length to 512")

[PATCH 6.1 204/225] test_firmware: fix a memory leak with reqs buffer

[Greg Kroah-Hartman]

From: Mirsad Goran Todorovac <mirsad.todorovac@alu.unizg.hr>

commit be37bed754ed90b2655382f93f9724b3c1aae847 upstream.

Dan Carpenter spotted that test_fw_config->reqs will be leaked if
trigger_batched_requests_store() is called two or more times.
The same appears with trigger_batched_requests_async_store().

This bug wasn't trigger by the tests, but observed by Dan's visual
inspection of the code.

The recommended workaround was to return -EBUSY if test_fw_config->reqs
is already allocated.

[PATCH 6.1 205/225] test_firmware: fix the memory leak of the allocated firmware buffer

[Greg Kroah-Hartman]

From: Mirsad Goran Todorovac <mirsad.todorovac@alu.unizg.hr>

commit 48e156023059e57a8fc68b498439832f7600ffff upstream.

The following kernel memory leak was noticed after running

Note that the size 1024 corresponds to the size of the test firmware
buffer. The actual number of the buffers leaked is around 70-110,
depending on the test run.

The cause of the leak is the following:

request_partial_firmware_into_buf() and request_firmware_into_buf()
provided firmware buffer isn't released on release_firmware(), we
have allocated it and we are responsible for deallocating it manually.
This is introduced in a number of context where previously only
release_firmware() was called, which was insufficient.

[PATCH 6.1 206/225] KVM: arm64: Populate fault info for watchpoint

[Greg Kroah-Hartman]

From: Akihiko Odaki <akihiko.odaki@daynix.com>

commit 811154e234db72f0a11557a84ba9640f8b3bc823 upstream.

When handling ESR_ELx_EC_WATCHPT_LOW, far_el2 member of struct
kvm_vcpu_fault_info will be copied to far member of struct
kvm_debug_exit_arch and exposed to the userspace. The userspace will
see stale values from older faults if the fault info does not get
populated.

[PATCH 6.1 207/225] KVM: x86: Account fastpath-only VM-Exits in vCPU stats

[Greg Kroah-Hartman]

From: Sean Christopherson <seanjc@google.com>

commit 8b703a49c9df5e74870381ad7ba9c85d8a74ed2c upstream.

Increment vcpu->stat.exits when handling a fastpath VM-Exit without
going through any part of the "slow" path.  Not bumping the exits stat
can result in wildly misleading exit counts, e.g. if the primary reason
the guest is exiting is to program the TSC deadline timer.

[PATCH 6.1 209/225] ksmbd: fix UAF issue from opinfo->conn

[Greg Kroah-Hartman]

From: Namjae Jeon <linkinjeon@kernel.org>

commit 36322523dddb11107e9f7f528675a0dec2536103 upstream.

If opinfo->conn is another connection and while ksmbd send oplock break
request to cient on current connection, The connection for opinfo->conn
can be disconnect and conn could be freed. When sending oplock break
request, this ksmbd_conn can be used and cause user-after-free issue.
When getting opinfo from the list, ksmbd check connection is being
released. If it is not released, Increase ->r_count to wait that connection
is freed.

[PATCH 6.1 210/225] ksmbd: fix incorrect AllocationSize set in smb2_get_info

[Greg Kroah-Hartman]

From: Namjae Jeon <linkinjeon@kernel.org>

commit 6cc2268f5647cbfde3d4fc2e4ee005070ea3a8d2 upstream.

If filesystem support sparse file, ksmbd should return allocated size
using ->i_blocks instead of stat->size. This fix generic/694 xfstests.

[PATCH 6.1 212/225] ksmbd: fix multiple out-of-bounds read during context decoding

[Greg Kroah-Hartman]

From: Kuan-Ting Chen <h3xrabbit@gmail.com>

commit 0512a5f89e1fae74251fde6893ff634f1c96c6fb upstream.

Check the remaining data length before accessing the context structure
to ensure that the entire structure is contained within the packet.
Additionally, since the context data length `ctxt_len` has already been
checked against the total packet length `len_of_ctxts`, update the
comparison to use `ctxt_len`.

[PATCH 6.1 213/225] KEYS: asymmetric: Copy sig and digest in public_key_verify_signature()

[Greg Kroah-Hartman]

From: Roberto Sassu <roberto.sassu@huawei.com>

commit c3d03e8e35e005e1a614e51bb59053eeb5857f76 upstream.

Commit ac4e97abce9b8 ("scatterlist: sg_set_buf() argument must be in linear
mapping") checks that both the signature and the digest reside in the
linear mapping area.

However, more recently commit ba14a194a434c ("fork: Add generic vmalloced
stack support") made it possible to move the stack in the vmalloc area,
which is not contiguous, and thus not suitable for sg_set_buf() which needs
adjacent pages.

Always make a copy of the signature and digest in the same buffer used to
store the key and its parameters, and pass them to sg_init_one(). Prefer it
to conditionally doing the copy if necessary, to keep the code simple. The
buffer allocated with kmalloc() is in the linear mapping area.

[PATCH 6.1 214/225] fs/ntfs3: Validate MFT flags before replaying logs

[Greg Kroah-Hartman]

From: Edward Lo <edward.lo@ambergroup.io>

commit 98bea253aa28ad8be2ce565a9ca21beb4a9419e5 upstream.

Log load and replay is part of the metadata handle flow during mount
operation. The $MFT record will be loaded and used while replaying logs.
However, a malformed $MFT record, say, has RECORD_FLAG_DIR flag set and
contains an ATTR_ROOT attribute will misguide kernel to treat it as a
directory, and try to free the allocated resources when the
corresponding inode is freed, which will cause an invalid kfree because
the memory hasn't actually been allocated.

[PATCH 6.1 215/225] regmap: Account for register length when chunking

[Greg Kroah-Hartman]

From: Jim Wylder <jwylder@google.com>

commit 3981514180c987a79ea98f0ae06a7cbf58a9ac0f upstream.

Currently, when regmap_raw_write() splits the data, it uses the
max_raw_write value defined for the bus.  For any bus that includes
the target register address in the max_raw_write value, the chunked
transmission will always exceed the maximum transmission length.
To avoid this problem, subtract the length of the register and the
padding from the maximum transmission.

[PATCH 6.1 216/225] tpm, tpm_tis: Request threaded interrupt handler

[Greg Kroah-Hartman]

From: Lino Sanfilippo <l.sanfilippo@kunbus.com>

commit 0c7e66e5fd69bf21034c9a9b081d7de7c3eb2cea upstream.

The TIS interrupt handler at least has to read and write the interrupt
status register. In case of SPI both operations result in a call to
tpm_tis_spi_transfer() which uses the bus_lock_mutex of the spi device
and thus must only be called from a sleepable context.

To ensure this request a threaded interrupt handler.

[PATCH 6.1 217/225] iommu/amd/pgtbl_v2: Fix domain max address

[Greg Kroah-Hartman]

From: Vasant Hegde <vasant.hegde@amd.com>

commit 11c439a19466e7feaccdbce148a75372fddaf4e9 upstream.

IOMMU v2 page table supports 4 level (47 bit) or 5 level (56 bit) virtual
address space. Current code assumes it can support 64bit IOVA address
space. If IOVA allocator allocates virtual address > 47/56 bit (depending
on page table level) then it will do wrong mapping and cause invalid
translation.

Hence adjust aperture size to use max address supported by the page table.

[PATCH 6.1 218/225] drm/amd/display: Have Payload Properly Created After Resume

[Greg Kroah-Hartman]

From: Fangzhi Zuo <jerry.zuo@amd.com>

commit 482e6ad9adde69d9da08864b4ccf4dfd53edb2f0 upstream.

At drm suspend sequence, MST dc_sink is removed. When commit cached
MST stream back in drm resume sequence, the MST stream payload is not
properly created and added into the payload table. After resume, topology
change is reprobed by removing existing streams first. That leads to
no payload is found in the existing payload table as below error
"[drm] ERROR No payload for [MST PORT:] found in mst state"

1. In encoder .atomic_check routine, remove check existance of dc_sink
2. Bypass MST by checking existence of MST root port. dc_link_type cannot
differentiate MST port before topology is rediscovered.

The fuzzed image contains an AGF with an obviously garbage
agf_refcount_level value of 32, and a dirty log with a buffer log item
for that AGF.  The ondisk AGF has a higher LSN than the recovered log
item.  xlog_recover_buf_commit_pass2 reads the buffer, compares the
LSNs, and decides to skip replay because the ondisk buffer appears to be
newer.

Unfortunately, the ondisk buffer is corrupt, but recovery just read the
buffer with no buffer ops specified:

	error = xfs_buf_read(mp->m_ddev_targp, buf_f->blf_blkno,
			buf_f->blf_len, buf_flags, &bp, NULL);

Skipping the buffer leaves its contents in memory unverified.  This sets
us up for a kernel crash because xfs_refcount_recover_cow_leftovers
reads the buffer (which is still around in XBF_DONE state, so no read
verification) and creates a refcountbt cursor of height 32.  This is
impossible so we run off the end of the cursor object and crash.

Fix this by invoking the verifier on all skipped buffers and aborting
log recovery if the ondisk buffer is corrupt.  It might be smarter to
force replay the log item atop the buffer and then see if it'll pass the
write verifier (like ext4 does) but for now let's go with the
conservative option where we stop immediately.

[PATCH 6.1 220/225] tls: rx: strp: dont use GFP_KERNEL in softirq context

[Greg Kroah-Hartman]

From: Jakub Kicinski <kuba@kernel.org>

commit 74836ec828fe17b63f2006fdbf53311d691396bf upstream.

When receive buffer is small, or the TCP rx queue looks too
complicated to bother using it directly - we allocate a new
skb and copy data into it.

We already use sk->sk_allocation... but nothing actually
sets it to GFP_ATOMIC on the ->sk_data_ready() path.

Users of HW offload are far more likely to experience problems
due to scheduling while atomic. "Copy mode" is very rarely
triggered with SW crypto.

[PATCH 6.1 221/225] arm64: efi: Use SMBIOS processor version to key off Ampere quirk

[Greg Kroah-Hartman]

From: Ard Biesheuvel <ardb@kernel.org>

commit eb684408f3ea4856639675d6465f0024e498e4b1 upstream.

Instead of using the SMBIOS type 1 record 'family' field, which is often
modified by OEMs, use the type 4 'processor ID' and 'processor version'
fields, which are set to a small set of probe-able values on all known
Ampere EFI systems in the field.

[PATCH 6.1 222/225] selftests: mptcp: diag: skip if MPTCP is not supported

[Greg Kroah-Hartman]

From: Matthieu Baerts <matthieu.baerts@tessares.net>

commit 46565acdd29facbf418a11e4a3791b3c8967308d upstream.

Selftests are supposed to run on any kernels, including the old ones not
supporting MPTCP.

A new check is then added to make sure MPTCP is supported. If not, the
test stops and is marked as "skipped".

[PATCH 6.1 224/225] selftests: mptcp: join: avoid using cmp --bytes

[Greg Kroah-Hartman]

From: Matthieu Baerts <matthieu.baerts@tessares.net>

commit d328fe87067480cf2bd0b58dab428a98d31dbb7e upstream.

BusyBox's 'cmp' command doesn't support the '--bytes' parameter.

Some CIs -- i.e. LKFT -- use BusyBox and have the mptcp_join.sh test
failing [1] because their 'cmp' command doesn't support this '--bytes'
option:

    cmp: unrecognized option '--bytes=1024'
    BusyBox v1.35.0 () multi-call binary.

    Usage: cmp [-ls] [-n NUM] FILE1 [FILE2]

Instead, 'head --bytes' can be used as this option is supported by
BusyBox. A temporary file is needed for this operation.

Because it is apparently quite common to use BusyBox, it is certainly
better to backport this fix to impacted kernels.

[PATCH 6.1 225/225] ext4: enable the lazy init thread when remounting read/write

[Greg Kroah-Hartman]

From: Theodore Ts'o <tytso@mit.edu>

commit eb1f822c76beeaa76ab8b6737ab9dc9f9798408c upstream.

In commit a44be64bbecb ("ext4: don't clear SB_RDONLY when remounting
r/w until quota is re-enabled") we defer clearing tyhe SB_RDONLY flag
in struct super.  However, we didn't defer when we checked sb_rdonly()
to determine the lazy itable init thread should be enabled, with the
next result that the lazy inode table initialization would not be
properly started.  This can cause generic/231 to fail in ext4's
nojournal mode.

Fix this by moving when we decide to start or stop the lazy itable
init thread to after we clear the SB_RDONLY flag when we are
remounting the file system read/write.

Fixes a44be64bbecb ("ext4: don't clear SB_RDONLY when remounting r/w until...")

Failed builds:
	loongarch:defconfig
	loongarch:allnoconfig
	loongarch:tinyconfig
	loongarch:allmodconfig

arch/loongarch/kernel/traps.c: In function 'trap_init':
arch/loongarch/kernel/traps.c:815:21: error: 'EXCCODE_BCE' undeclared

EXCCODE_BCE is indeed undeclared in v6.1.y.

Commit 'LoongArch: Relay BCE exceptions to userland as SIGSEGV with si_code=SEGV_BNDERR'
is not marked Fixes: or stable: and should arguably not have been backported.

The same problem affects 6.3.
