5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Siddh Raman Pant <code@siddh.me>
[ Upstream commit c95f919567d6f1914f13350af61a1b044ac85014 ]
llcp_sock_sendmsg() calls nfc_llcp_send_ui_frame() which in turn calls
nfc_alloc_send_skb(), which accesses the nfc_dev from the llcp_sock for
getting the headroom and tailroom needed for skb allocation.
Parallelly the nfc_dev can be freed, as the refcount is decreased via
nfc_free_device(), leading to a UAF reported by Syzkaller, which can
be summarized as follows:
(1) llcp_sock_sendmsg() -> nfc_llcp_send_ui_frame()
-> nfc_alloc_send_skb() -> Dereference *nfc_dev
(2) virtual_ncidev_close() -> nci_free_device() -> nfc_free_device()
-> put_device() -> nfc_release() -> Free *nfc_dev
When a reference to llcp_local is acquired, we do not acquire the same
for the nfc_dev. This leads to freeing even when the llcp_local is in
use, and this is the case with the UAF described above too.
Thus, when we acquire a reference to llcp_local, we should acquire a
reference to nfc_dev, and release the references appropriately later.
References for llcp_local is initialized in nfc_llcp_register_device()
(which is called by nfc_register_device()). Thus, we should acquire a
reference to nfc_dev there.
nfc_unregister_device() calls nfc_llcp_unregister_device() which in
turn calls nfc_llcp_local_put(). Thus, the reference to nfc_dev is
appropriately released later.

------------------
From: Jörn-Thorben Hinz <jthinz@mailbox.tu-berlin.de>
[ Upstream commit 7f6ca95d16b96567ce4cf458a2790ff17fa620c3 ]
Commit 9718475e6908 ("socket: Add SO_TIMESTAMPING_NEW") added the new
socket option SO_TIMESTAMPING_NEW. Setting the option is handled in
sk_setsockopt(), querying it was not handled in sk_getsockopt(), though.
Following remarks on an earlier submission of this patch, keep the old
behavior of getsockopt(SO_TIMESTAMPING_OLD) which returns the active
flags even if they actually have been set through SO_TIMESTAMPING_NEW.
The new getsockopt(SO_TIMESTAMPING_NEW) is stricter, returning flags
only if they have been set through the same option.

Hi Greg,
this patch is applied in the wrong place (the wrong case) here in
sock_getsockopt(). The function seems to have changed in a number of
places after 5.4, apparently too much for an automatic(?!) merge.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Marc Kleine-Budde <mkl@pengutronix.de>
[ Upstream commit 51a0d5e51178fcd147c1b8fdab2ed16b561326db ]
This patch calls into sock_cmsg_send() to parse the user supplied
control information into a struct sockcm_cookie. Then assign the
requested transmit time to the skb.
This makes it possible to use the Earliest TXTIME First (ETF) packet
scheduler with the CAN_RAW protocol. The user can send a CAN_RAW frame
with a TXTIME and the kernel (with the ETF scheduler) will take care
of sending it to the network interface.

[ Upstream commit 8ca5a5790b9a1ce147484d2a2c4e66d2553f3d6c ]
When the feature was added it was enabled for SW timestamps only but
with current hardware the same out-of-order timestamps can be seen.
Let's expand the area for the feature to all types of timestamps.

From: Stefan Wahren <wahrenst@gmx.net>
[ Upstream commit 72ad3b772b6d393701df58ba1359b0bb346a19ed ]
Running a multi-arch kernel (multi_v7_defconfig) on a Raspberry Pi 3B+
with enabled CONFIG_UBSAN triggers the following warning:
UBSAN: array-index-out-of-bounds in arch/arm/mach-sunxi/mc_smp.c:810:29

Since the enabled method couldn't match with any entry from
sunxi_mc_smp_data, the value of the index shouldn't be used right after
the loop. So move it after the check of ret in order to have a valid
index.

From: Adrian Cinal <adriancinal@gmail.com>
[ Upstream commit e584f2ff1e6cc9b1d99e8a6b0f3415940d1b3eb3 ]
The flag DMA_TX_APPEND_CRC was only written to the first DMA descriptor
in the TX path, where each descriptor corresponds to a single skbuff
fragment (or the skbuff head). This led to packets with no FCS appearing
on the wire if the kernel allocated the packet in fragments, which would
always happen when using PACKET_MMAP/TPACKET (cf. tpacket_fill_skb() in
net/af_packet.c).

From: Marc Dionne <marc.dionne@auristor.com>
[ Upstream commit 01b2885d9415152bcb12ff1f7788f500a74ea0ed ]
Commit 86a7e0b69bd5 ("net: prevent rewrite of msg_name in
sock_sendmsg()") made sock_sendmsg save the incoming msg_name pointer
and restore it before returning, to insulate the caller against
msg_name being changed by the called code. If the address length
was also changed however, we may return with an inconsistent structure
where the length doesn't match the address, and attempts to reuse it may
lead to lost packets.
For example, a kernel that doesn't have commit 1c5950fc6fe9 ("udp6: fix
potential access to stale information") will replace a v4 mapped address
with its ipv4 equivalent, and shorten namelen accordingly from 28 to 16.
If the caller attempts to reuse the resulting msg structure, it will have
the original ipv6 (v4 mapped) address but an incorrect v4 length.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Ke Xiao <xiaoke@sangfor.com.cn>
[ Upstream commit 6a15584e99db8918b60e507539c7446375dcf366 ]
Commit 3116f59c12bd ("i40e: fix use-after-free in
i40e_sync_filters_subtask()") avoided use-after-free issues,
by increasing refcount during update the VSI filter list to
the HW. However, it missed the unicast situation.
When deleting an unicast FDB entry, the i40e driver will release
the mac_filter, and i40e_service_task will concurrently request
firmware to add the mac_filter, which will lead to the following
use-after-free issue.
Fix again for both netdev->uc and netdev->mc.

From: Jerome Brunet <jbrunet@baylibre.com>
[ Upstream commit 9c29fd9bdf92900dc0cc5c2d8f58951a7bdc0f41 ]
The hdmi routing mechanism used on g12a hdmi is also used:
* other Amlogic SoC types
* for the internal DAC path
Each of these codec glues are slightly different but the idea
behind it remains the same. This change extract some helper functions
from the g12a-tohdmitx driver to make them available for other Amlogic
codecs.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mark Brown <broonie@kernel.org>
[ Upstream commit 1e001206804be3f3d21f4a1cf16e5d059d75643f ]
When writing to an enum we need to verify that the value written is valid
for the enumeration, the helper function snd_soc_item_enum_to_val() doesn't
do it since it needs to return an unsigned (and in any case we'd need to
check the return value).

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mark Brown <broonie@kernel.org>
[ Upstream commit b036d8ef3120b996751495ce25994eea58032a98 ]
When a control changes value the return value from _put() should be 1 so
we get events generated to userspace notifying applications of the change.
While the I2S mux gets this right the S/PDIF mux does not, fix the return
value.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Andrii Staikov <andrii.staikov@intel.com>
[ Upstream commit 371e576ff3e8580d91d49026e5d5faebf5565558 ]
During a PCI FLR the MSI-X Enable flag in the VF PCI MSI-X capability
register will be cleared. This can lead to issues when a VF is
assigned to a VM because in these cases the VF driver receives no
indication of the PF PCI error/reset and additionally it is incapable
of restoring the cleared flag in the hypervisor configuration space
without fully reinitializing the driver interrupt functionality.
Since the VF driver is unable to easily resolve this condition on its own,
restore the VF MSI-X flag during the PF PCI reset handling.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>
[ Upstream commit 41fb4c1ba7478fe34c7e094e124e4ee4513b9763 ]
The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.
When memory is allocated in 'ql_alloc_net_req_rsp_queues()' GFP_KERNEL can
be used because it is only called from 'ql_alloc_mem_resources()' which
already calls 'ql_alloc_buffer_queues()' which uses GFP_KERNEL. (see below)
When memory is allocated in 'ql_alloc_buffer_queues()' GFP_KERNEL can be
used because this flag is already used just a few line above.
When memory is allocated in 'ql_alloc_small_buffers()' GFP_KERNEL can
be used because it is only called from 'ql_alloc_mem_resources()' which
already calls 'ql_alloc_buffer_queues()' which uses GFP_KERNEL. (see above)
When memory is allocated in 'ql_alloc_mem_resources()' GFP_KERNEL can be
used because this function already calls 'ql_alloc_buffer_queues()' which
uses GFP_KERNEL. (see above)
While at it, use 'dma_set_mask_and_coherent()' instead of 'dma_set_mask()/
dma_set_coherent_mask()' in order to slightly simplify code.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Takashi Sakamoto <o-takashi@sakamocchi.jp>
commit ac9184fbb8478dab4a0724b279f94956b69be827 upstream.
VIA VT6306/6307/6308 provides PCI interface compliant to 1394 OHCI. When
the hardware is combined with Asmedia ASM1083/1085 PCIe-to-PCI bus bridge,
it appears that accesses to its 'Isochronous Cycle Timer' register (offset
0xf0 on PCI memory space) often causes unexpected system reboot in any
type of AMD Ryzen machine (both 0x17 and 0x19 families). It does not
appears in the other type of machine (AMD pre-Ryzen machine, Intel
machine, at least), or in the other OHCI 1394 hardware (e.g. Texas
Instruments).
The issue explicitly appears at a commit dcadfd7f7c74 ("firewire: core:
use union for callback of transaction completion") added to v6.5 kernel.
It changed 1394 OHCI driver to access to the register every time to
dispatch local asynchronous transaction. However, the issue exists in
older version of kernel as long as it runs in AMD Ryzen machine, since
the access to the register is required to maintain bus time. It is not
hard to imagine that users experience the unexpected system reboot when
generating bus reset by plugging any devices in, or reading the register
by time-aware application programs; e.g. audio sample processing.
This commit suppresses the unexpected system reboot in the combination of
hardware. It avoids the access itself. As a result, the software stack can
not provide the hardware time anymore to unit drivers, userspace
applications, and nodes in the same IEEE 1394 bus. It brings apparent
disadvantage since time-aware application programs require it, while
time-unaware applications are available again; e.g. sbp2.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Benjamin Bara <benjamin.bara@skidata.com>
commit a3368e1186e3ce8e38f78cbca019622095b1f331 upstream.
Since commit aa49c90894d0 ("i2c: core: Run atomic i2c xfer when
!preemptible"), the whole reboot/power off sequence on non-preempt kernels
is using atomic i2c xfer, as !preemptible() always results to 1.
During device_shutdown(), the i2c might be used a lot and not all busses
have implemented an atomic xfer handler. This results in a lot of
avoidable noise, like:
[ 12.687169] No atomic I2C transfer handler for 'i2c-0'
[ 12.692313] WARNING: CPU: 6 PID: 275 at drivers/i2c/i2c-core.h:40 i2c_smbus_xfer+0x100/0x118
...
Fix this by allowing non-atomic xfer when the interrupts are enabled, as
it was before.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jiajun Xie <jiajun.xie.sh@gmail.com>
commit 9eab0421fa94a3dde0d1f7e36ab3294fc306c99d upstream.
The bug happens when highest bit of holebegin is 1, suppose holebegin is
0x8000000111111000, after shift, hba would be 0xfff8000000111111, then
vma_interval_tree_foreach would look it up fail or leads to the wrong
result.
error call seq e.g.:
- mmap(..., offset=0x8000000111111000)
|- syscall(mmap, ... unsigned long, off):
|- ksys_mmap_pgoff( ... , off >> PAGE_SHIFT);
here pgoff is correctly shifted to 0x8000000111111,
but pass 0x8000000111111000 as holebegin to unmap
would then cause terrible result, as shown below:
- unmap_mapping_range(..., loff_t const holebegin)
|- pgoff_t hba = holebegin >> PAGE_SHIFT;
/* hba = 0xfff8000000111111 unexpectedly */
The issue happens in Heterogeneous computing, where the device(e.g.
gpu) and host share the same virtual address space.
A simple workflow pattern which hit the issue is:
/* host */
1. userspace first mmap a file backed VA range with specified offset.
e.g. (offset=0x800..., mmap return: va_a)
2. write some data to the corresponding sys page
e.g. (va_a = 0xAABB)
/* device */
3. gpu workload touches VA, triggers gpu fault and notify the host.
/* host */
4. reviced gpu fault notification, then it will:
4.1 unmap host pages and also takes care of cpu tlb
(use unmap_mapping_range with offset=0x800...)
4.2 migrate sys page to device
4.3 setup device page table and resolve device fault.
/* device */
5. gpu workload continued, it accessed va_a and got 0xAABB.
6. gpu workload continued, it wrote 0xBBCC to va_a.
/* host */
7. userspace access va_a, as expected, it will:
7.1 trigger cpu vm fault.
7.2 driver handling fault to migrate gpu local page to host.
8. userspace then could correctly get 0xBBCC from va_a
9. done
But in step 4.1, if we hit the bug this patch mentioned, then userspace
would never trigger cpu fault, and still get the old value: 0xAABB.
Making holebegin unsigned first fixes the bug.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jorge Ramirez-Ortiz <jorge@foundries.io>
commit e7794c14fd73e5eb4a3e0ecaa5334d5a17377c50 upstream.
When RPMB was converted to a character device, it added support for
multiple RPMB partitions (Commit 97548575bef3 ("mmc: block: Convert RPMB to
a character device").
One of the changes in this commit was transforming the variable target_part
defined in __mmc_blk_ioctl_cmd into a bitmask. This inadvertently regressed
the validation check done in mmc_blk_part_switch_pre() and
mmc_blk_part_switch_post(), so let's fix it.

When expire_timers() runs later, it warns because the MMC host structure
containing the delayed work was freed, and now contains an invalid work
function pointer.
Fix this by cancelling any pending delayed work before releasing the
MMC host structure.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Douglas Anderson <dianders@chromium.org>
[ Upstream commit 8f9ed93d09a97444733d492a3bbf66bcb786a777 ]
On wcn3990 we have "per_ce_irq = true". That makes the
ath10k_ce_interrupt_summary() function always return 0xfff. The
ath10k_ce_per_engine_service_any() function will see this and think
that _all_ copy engines have an interrupt. Without checking, the
ath10k_ce_per_engine_service() assumes that if it's called that the
"copy complete" (cc) interrupt fired. This combination seems bad.
Let's add a check to make sure that the "copy complete" interrupt
actually fired in ath10k_ce_per_engine_service().
This might fix a hard-to-reproduce failure where it appears that the
copy complete handlers run before the copy is really complete.
Specifically a symptom was that we were seeing this on a Qualcomm
sc7180 board:
arm-smmu 15000000.iommu: Unhandled context fault:
fsr=0x402, iova=0x7fdd45780, fsynr=0x30003, cbfrsynra=0xc1, cb=10
Even on platforms that don't have wcn3990 this still seems like it
would be a sane thing to do. Specifically the current IRQ handler
comments indicate that there might be other misc interrupt sources
firing that need to be cleared. If one of those sources was the one
that caused the IRQ handler to be called it would also be important to
double-check that the interrupt we cared about actually fired.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Rakesh Pillai <pillair@codeaurora.org>
[ Upstream commit b92aba35d39d10d8a6bdf2495172fd490c598b4a ]
Currently the NAPI processing loops through all
the copy engines and processes a particular copy
engine is the copy completion is set for that copy
engine. The host driver is not supposed to access
any copy engine register after clearing the interrupt
status register.
This might result in kernel crash like the one below
[ 1159.220143] Call trace:
[ 1159.220170] ath10k_snoc_read32+0x20/0x40 [ath10k_snoc]

[ 1159.220423] ret_from_fork+0x10/0x18
To avoid such a scenario, we generate an interrupt
summary by reading the copy completion for all the
copy engine before actually processing any of them.
This will avoid reading the interrupt status register
for any CE after the interrupt status is cleared.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Douglas Anderson <dianders@chromium.org>
[ Upstream commit d66d24ac300cf41c6b88367fc9b4b6348679273d ]
If we have a per CE (Copy Engine) IRQ then we have no summary
register. Right now the code generates a summary register by
iterating over all copy engines and seeing if they have an interrupt
pending.
This has a problem. Specifically if _none_ if the Copy Engines have
an interrupt pending then they might go into low power mode and
reading from their address space will cause a full system crash. This
was seen to happen when two interrupts went off at nearly the same
time. Both were handled by a single call of ath10k_snoc_napi_poll()
but, because there were two interrupts handled and thus two calls to
napi_schedule() there was still a second call to
ath10k_snoc_napi_poll() which ran with no interrupts pending.
Instead of iterating over all the copy engines, let's just keep track
of the IRQs that fire. Then we can effectively generate our own
summary without ever needing to read the Copy Engines.

The curr pointer must also be updated on the splice similar to how
we do this for other copy types.

------------------
From: Phil Sutter <phil@nwl.cc>
commit f1082dd31fe461d482d69da2a8eccfeb7bf07ac2 upstream.
An nftables family is merely a hollow container, its family just a
number and such not reliant on compile-time options other than nftables
support itself. Add an artificial check so attempts at using a family
the kernel can't support fail as early as possible. This helps user
space detect kernels which lack e.g. NFPROTO_INET.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bartosz Pawlowski <bartosz.pawlowski@intel.com>
commit a18615b1cfc04f00548c60eb9a77e0ce56e848fd upstream.
Due to a hardware issue in A and B steppings of Intel IPU E2000, it expects
wrong endianness in ATS invalidation message body. This problem can lead to
outdated translations being returned as valid and finally cause system
instability.
To prevent such issues, add quirk_intel_e2000_no_ats() to disable ATS for
vulnerable IPU E2000 devices.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <edumazet@google.com>
commit cf86a086a18095e33e0637cb78cda1fcf5280852 upstream.
percpu_counter_add() uses a default batch size which is quite big
on platforms with 256 cpus. (2*256 -> 512)
This means dst_entries_get_fast() can be off by +/- 2*(nr_cpus^2)
(131072 on servers with 256 cpus)
Reduce the batch size to something more reasonable, and
add logic to ip6_dst_gc() to call dst_entries_get_slow()
before calling the _very_ expensive fib6_run_gc() function.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Dumazet <edumazet@google.com>
commit 9cb7c013420f98fa6fd12fc6a5dc055170c108db upstream.
Reads and Writes to ip6_rt_gc_expire always have been racy,
as syzbot reported lately [1]
There is a possible risk of under-flow, leading
to unexpected high value passed to fib6_run_gc(),
although I have not observed this in the field.
Hosts hitting ip6_dst_gc() very hard are under pretty bad
state anyway.

5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jon Maxwell <jmaxwell37@gmail.com>
commit af6d10345ca76670c1b7c37799f0d5576ccef277 upstream.
In ip6_dst_gc() replace:
if (entries > gc_thresh)
With:
if (entries > ops->gc_thresh)
Sending Ipv6 packets in a loop via a raw socket triggers an issue where a
route is cloned by ip6_rt_cache_alloc() for each packet sent. This quickly
consumes the Ipv6 max_size threshold which defaults to 4096 resulting in
these warnings:
[1] 99.187805] dst_alloc: 7728 callbacks suppressed
[2] Route cache is full: consider increasing sysctl net.ipv6.route.max_size.
.
.
[300] Route cache is full: consider increasing sysctl net.ipv6.route.max_size.
When this happens the packet is dropped and sendto() gets a network is
unreachable error:
remaining pkt 200557 errno 101
remaining pkt 196462 errno 101
.
.
remaining pkt 126821 errno 101
Implement David Aherns suggestion to remove max_size check seeing that Ipv6
has a GC to manage memory usage. Ipv4 already does not check max_size.
Here are some memory comparisons for Ipv4 vs Ipv6 with the patch:
Test by running 5 instances of a program that sends UDP packets to a raw
socket 5000000 times. Compare Ipv4 and Ipv6 performance with a similar
program.
