[PATCH 5.4 03/13] ACPI: NFIT: fix a potential deadlock during NFIT teardown

[Greg Kroah-Hartman]

From: Vishal Verma <vishal.l.verma@intel.com>

[ Upstream commit fb6df4366f86dd252bfa3049edffa52d17e7b895 ]

Lockdep reports that acpi_nfit_shutdown() may deadlock against an
opportune acpi_nfit_scrub(). acpi_nfit_scrub () is run from inside a
'work' and therefore has already acquired workqueue-internal locks. It
also acquiires acpi_desc->init_mutex. acpi_nfit_shutdown() first
acquires init_mutex, and was subsequently attempting to cancel any
pending workqueue items. This reversed locking order causes a potential
deadlock:

    ======================================================
    WARNING: possible circular locking dependency detected
    6.2.0-rc3 #116 Tainted: G           O     N
    ------------------------------------------------------
    libndctl/1958 is trying to acquire lock:
    ffff888129b461c0 ((work_completion)(&(&acpi_desc->dwork)->work)){+.+.}-{0:0}, at: __flush_work+0x43/0x450

    but task is already holding lock:
    ffff888129b460e8 (&acpi_desc->init_mutex){+.+.}-{3:3}, at: acpi_nfit_shutdown+0x87/0xd0 [nfit]

    which lock already depends on the new lock.

    ...

    Possible unsafe locking scenario:

          CPU0                    CPU1
          ----                    ----
     lock(&acpi_desc->init_mutex);
                                  lock((work_completion)(&(&acpi_desc->dwork)->work));
                                  lock(&acpi_desc->init_mutex);
     lock((work_completion)(&(&acpi_desc->dwork)->work));

    *** DEADLOCK ***

Since the workqueue manipulation is protected by its own internal locking,
the cancellation of pending work doesn't need to be done under
acpi_desc->init_mutex. Move cancel_delayed_work_sync() outside the
init_mutex to fix the deadlock. Any work that starts after
acpi_nfit_shutdown() drops the lock will see ARS_CANCEL, and the
cancel_delayed_work_sync() will safely flush it out.

[PATCH 5.4 04/13] btrfs: send: limit number of clones and allocated memory size

[Greg Kroah-Hartman]

From: David Sterba <dsterba@suse.com>

[ Upstream commit 33e17b3f5ab74af12aca58c515bc8424ff69a343 ]

The arg->clone_sources_count is u64 and can trigger a warning when a
huge value is passed from user space and a huge array is allocated.
Limit the allocated memory to 8MiB (can be increased if needed), which
in turn limits the number of clone sources to 8M / sizeof(struct
clone_root) = 8M / 40 = 209715.  Real world number of clones is from
tens to hundreds, so this is future proof.

[PATCH 5.4 06/13] neigh: make sure used and confirmed times are valid

[Greg Kroah-Hartman]

From: Julian Anastasov <ja@ssi.bg>

[ Upstream commit c1d2ecdf5e38e3489ce8328238b558b3b2866fe1 ]

Entries can linger in cache without timer for days, thanks to
the gc_thresh1 limit. As result, without traffic, the confirmed
time can be outdated and to appear to be in the future. Later,
on traffic, NUD_STALE entries can switch to NUD_DELAY and start
the timer which can see the invalid confirmed time and wrongly
switch to NUD_REACHABLE state instead of NUD_PROBE. As result,
timer is set many days in the future. This is more visible on
32-bit platforms, with higher HZ value.

Why this is a problem? While we expect unused entries to expire,
such entries stay in REACHABLE state for too long, locked in
cache. They are not expired normally, only when cache is full.

Problem and the wrong state change reported by Zhang Changzhong:

172.16.1.18 dev bond0 lladdr 0a:0e:0f:01:12:01 ref 1 used 350521/15994171/350520 probes 4 REACHABLE

350520 seconds have elapsed since this entry was last updated, but it is
still in the REACHABLE state (base_reachable_time_ms is 30000),
preventing lladdr from being updated through probe.

Fix it by ensuring timer is started with valid used/confirmed
times. Considering the valid time range is LONG_MAX jiffies,
we try not to go too much in the past while we are in
DELAY/PROBE state. There are also places that need
used/updated times to be validated while timer is not running.

[PATCH 5.4 07/13] HID: core: Fix deadloop in hid_apply_multiplier.

[Greg Kroah-Hartman]

From: Xin Zhao <xnzhao@google.com>

[ Upstream commit ea427a222d8bdf2bc1a8a6da3ebe247f7dced70c ]

The initial value of hid->collection[].parent_idx if 0. When
Report descriptor doesn't contain "HID Collection", the value
remains as 0.

In the meanwhile, when the Report descriptor fullfill
all following conditions, it will trigger hid_apply_multiplier
function call.
1. Usage page is Generic Desktop Ctrls (0x01)
2. Usage is RESOLUTION_MULTIPLIER (0x48)
3. Contain any FEATURE items

The while loop in hid_apply_multiplier will search the top-most
collection by searching parent_idx == -1. Because all parent_idx
is 0. The loop will run forever.

There is a Report Descriptor triggerring the deadloop
0x05, 0x01,        // Usage Page (Generic Desktop Ctrls)
0x09, 0x48,        // Usage (0x48)

[PATCH 5.4 08/13] bpf: bpf_fib_lookup should not return neigh in NUD_FAILED state

[Greg Kroah-Hartman]

From: Martin KaFai Lau <martin.lau@kernel.org>

commit 1fe4850b34ab512ff911e2c035c75fb6438f7307 upstream.

The bpf_fib_lookup() helper does not only look up the fib (ie. route)
but it also looks up the neigh. Before returning the neigh, the helper
does not check for NUD_VALID. When a neigh state (neigh->nud_state)
is in NUD_FAILED, its dmac (neigh->ha) could be all zeros. The helper
still returns SUCCESS instead of NO_NEIGH in this case. Because of the
SUCCESS return value, the bpf prog directly uses the returned dmac
and ends up filling all zero in the eth header.

This patch checks for NUD_VALID and returns NO_NEIGH if the neigh is
not valid.

[PATCH 5.4 09/13] net: Remove WARN_ON_ONCE(sk->sk_forward_alloc) from sk_stream_kill_queues().

[Greg Kroah-Hartman]

From: Kuniyuki Iwashima <kuniyu@amazon.com>

commit 62ec33b44e0f7168ff2886520fec6fb62d03b5a3 upstream.

Christoph Paasch reported that commit b5fc29233d28 ("inet6: Remove
inet6_destroy_sock() in sk->sk_prot->destroy().") started triggering
WARN_ON_ONCE(sk->sk_forward_alloc) in sk_stream_kill_queues().  [0 - 2]
Also, we can reproduce it by a program in [3].

In the commit, we delay freeing ipv6_pinfo.pktoptions from sk->destroy()
to sk->sk_destruct(), so sk->sk_forward_alloc is no longer zero in
inet_csk_destroy_sock().

The same check has been in inet_sock_destruct() from at least v2.6,
we can just remove the WARN_ON_ONCE().  However, among the users of
sk_stream_kill_queues(), only CAIF is not calling inet_sock_destruct().
Thus, we add the same WARN_ON_ONCE() to caif_sock_destructor().

[PATCH 5.4 10/13] vc_screen: dont clobber return value in vcs_read

[Greg Kroah-Hartman]

From: Thomas Weißschuh <linux@weissschuh.net>

commit ae3419fbac845b4d3f3a9fae4cc80c68d82cdf6e upstream.

Commit 226fae124b2d ("vc_screen: move load of struct vc_data pointer in
vcs_read() to avoid UAF") moved the call to vcs_vc() into the loop.

While doing this it also moved the unconditional assignment of

	ret = -ENXIO;

This unconditional assignment was valid outside the loop but within it
it clobbers the actual value of ret.

To avoid this only assign "ret = -ENXIO" when actually needed.

[ Also, the 'goto unlock_out" needs to be just a "break", so that it
  does the right thing when it exits on later iterations when partial
  success has happened - Linus ]

better to check the return value of the dma_set_max_seg_size().

[PATCH 5.4 13/13] USB: core: Dont hold device lock while reading the "descriptors" sysfs file

[Greg Kroah-Hartman]

From: Alan Stern <stern@rowland.harvard.edu>

commit 45bf39f8df7f05efb83b302c65ae3b9bc92b7065 upstream.

Ever since commit 83e83ecb79a8 ("usb: core: get config and string
descriptors for unauthorized devices") was merged in 2013, there has
been no mechanism for reallocating the rawdescriptors buffers in
struct usb_device after the initial enumeration.  Before that commit,
the buffers would be deallocated when a device was deauthorized and
reallocated when it was authorized and enumerated.

This means that the locking in the read_descriptors() routine is not
needed, since the buffers it reads will never be reallocated while the
routine is running.  This locking can interfere with user programs
trying to read a hub's descriptors via sysfs while new child devices
of the hub are being initialized, since the hub is locked during this
procedure.

Since the locking in read_descriptors() hasn't been needed for over
nine years, we can remove it.
