eba7c58b7a wifi: ath11k: initialize 'ret' in ath11k_qmi_load_file_target_mem()
[ Upstream commit 199f149e97dc7be80e5eed4b232529c1d1aa8055 ]

smatch flagged the following issue:

drivers/net/wireless/ath/ath11k/qmi.c:2401 ath11k_qmi_load_file_target_mem() error: uninitialized symbol 'ret'.

The reality is that 'ret' is initialized in every path through
ath11k_qmi_load_file_target_mem() except one, the case where the input
'len' is 0, and hence the "while (remaining)" loop is never entered.
But to make sure this case is also handled, add an initializer to the
declaration of 'ret'.

No functional changes, compile tested only.

59f742e55a apparmor: fix possible NULL pointer dereference
[ Upstream commit 3dd384108d53834002be5630132ad5c3f32166ad ]

profile->parent->dents[AAFS_PROF_DIR] could be NULL only if its parent is made
from __create_missing_ancestors(..) and 'ent->old' is NULL in
aa_replace_profiles(..).
In that case, it must return an error code and the code, -ENOENT represents
its state that the path of its parent is not existed yet.

f163ba83e6 drm/amdkfd: Reconcile the definition and use of oem_id in struct kfd_topology_device
[ Upstream commit 10f624ef239bd136cdcc5bbc626157a57b938a31 ]

Currently oem_id is defined as uint8_t[6] and casted to uint64_t*
in some use case. This would lead code scanner to complain about
access beyond. Re-define it in union to enforce 8-byte size and
alignment to avoid potential issue.

In interrupt context, write dbg_ev_file will be run by work queue. It
will cause write dbg_ev_file execution after debug_trap_disable, which
will cause NULL pointer access.

[ Upstream commit 83c0c8361347cf43937348e8ca0a487679c003ae ]

[Why]
For addtion (uint8_t) variable + constant 1,
coverity generates message below:
Truncation due to cast operation on "cur_idx + 1" from
32 to 8 bits.

Then Coverity assume result is 32 bits value be saved into
8 bits variable. When result is used as index to access
array, Coverity suspects index invalid.

[How]
Change varaible type to uint32_t.

3d2e1b8255 mptcp: pr_debug: add missing \n at the end
commit cb41b195e634d3f1ecfcd845314e64fd4bb3c7aa upstream.

pr_debug() have been added in various places in MPTCP code to help
developers to debug some situations. With the dynamic debug feature, it
is easy to enable all or some of them, and asks users to reproduce
issues with extra debug.

Many of these pr_debug() don't end with a new line, while no 'pr_cont()'
are used in MPTCP code. So the goal was not to display multiple debug
messages on one line: they were then not missing the '\n' on purpose.
Not having the new line at the end causes these messages to be printed
with a delay, when something else needs to be printed. This issue is not
visible when many messages need to be printed, but it is annoying and
confusing when only specific messages are expected, e.g.

  # echo "func mptcp_pm_add_addr_echoed +fmp" \
        > /sys/kernel/debug/dynamic_debug/control
  # ./mptcp_join.sh "signal address"; \
        echo "$(awk '{print $1}' /proc/uptime) - end"; \
        sleep 5s; \
        echo "$(awk '{print $1}' /proc/uptime) - restart"; \
        ./mptcp_join.sh "signal address"
  013 signal address
      (...)
  10.75 - end
  15.76 - restart
  013 signal address
  [  10.367935] mptcp:mptcp_pm_add_addr_echoed: MPTCP: msk=(...)
      (...)

  => a delay of 5 seconds: printed with a 10.36 ts, but after 'restart'
     which was printed at the 15.76 ts.

The 'Fixes' tag here below points to the first pr_debug() used without
'\n' in net/mptcp. This patch could be split in many small ones, with
different Fixes tag, but it doesn't seem worth it, because it is easy to
re-generate this patch with this simple 'sed' command:

  git grep -l pr_debug -- net/mptcp |
    xargs sed -i "s/\(pr_debug(\".*[^n]\)\(\"[,)]\)/\1\\\n\2/g"

So in case of conflicts, simply drop the modifications, and launch this
command.

a088190f3f mptcp: avoid duplicated SUB_CLOSED events
commit d82809b6c5f2676b382f77a5cbeb1a5d91ed2235 upstream.

The initial subflow might have already been closed, but still in the
connection list. When the worker is instructed to close the subflows
that have been marked as closed, it might then try to close the initial
subflow again.

 A consequence of that is that the SUB_CLOSED event can be seen twice:

  # ip mptcp endpoint
  1.1.1.1 id 1 subflow dev eth0
  2.2.2.2 id 2 subflow dev eth1

  # ip mptcp monitor &
  [         CREATED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9
  [     ESTABLISHED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9
  [  SF_ESTABLISHED] remid=0 locid=2 saddr4=2.2.2.2 daddr4=9.9.9.9

  # ip mptcp endpoint delete id 1
  [       SF_CLOSED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9
  [       SF_CLOSED] remid=0 locid=0 saddr4=1.1.1.1 daddr4=9.9.9.9

The first one is coming from mptcp_pm_nl_rm_subflow_received(), and the
second one from __mptcp_close_subflow().

To avoid doing the post-closed processing twice, the subflow is now
marked as closed the first time.

Note that it is not enough to check if we are dealing with the first
subflow and check its sk_state: the subflow might have been reset or
closed before calling mptcp_close_ssk().

This new test has recently been queued to v6.6 [1] with the backport of

The modification here was part of commit 04b57c9e096a ("selftests:

backported to v6.6 a few months ago -- see commit 358f02b84f
("selftests: mptcp: join: stop transfer when check is done (part 2)") --
but it was not modifying this subtest as it was not present in v6.6.

5803af655f selftests: mptcp: join: disable get and dump addr checks
These new checks have been recently queued to v6.6 [1] with the backport
of commit 38f027fca1b7 ("selftests: mptcp: dump userspace addrs list"),
and commit 4cc5cc7ca052 ("selftests: mptcp: userspace pm get addr
tests").

On v6.6, these checks will simply print 'skip', because the associated
features are not available in this version. That's fine, except that the
MPTCP CI sets the SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES=1 env var,
which will force these subtests to fail when using the selftests from
v6.6 on a v6.6 kernel, because the feature is not available.

To ease the backports (and possible future ones), I suggest to keep the
recent backports, but skip calling mptcp_lib_kallsyms_has() not to have
the CIs setting this env var complaining about the associated features
not being available.

This test extends "delete re-add signal" to validate the previous
commit: when the 'signal' endpoint linked to the initial subflow (ID 0)
is re-added multiple times, it will re-send the ADD_ADDR with id 0. The
client should still be able to re-create this subflow, even if the
add_addr_accepted limit has been reached as this special address is not
considered as a new address.

b66609e9aa selftests: mptcp: add mptcp_lib_events helper
commit 35bc143a8514ee72b2e9d6b8b385468608b93a53 upstream.

To avoid duplicated code in different MPTCP selftests, we can add and
use helpers defined in mptcp_lib.sh.

This patch unifies "pm_nl_ctl events" related code in userspace_pm.sh
and mptcp_join.sh into a helper mptcp_lib_events(). Define it in
mptcp_lib.sh and use it in both scripts.

Note that mptcp_lib_kill_wait is now call before starting 'events' for
mptcp_join.sh as well, but that's fine: each test is started from a new
netns, so there will not be any existing pid there, and nothing is done
when mptcp_lib_kill_wait is called with 0.

0a37a0ec0d selftests: mptcp: join: check re-adding init endp with != id
[ Upstream commit 1c2326fcae4f0c5de8ad0d734ced43a8e5f17dac ]

The initial subflow has a special local ID: 0. It is specific per
connection.

When a global endpoint is deleted and re-added later, it can have a
different ID, but the kernel should still use the ID 0 if it corresponds
to the initial address.

This test validates this behaviour: the endpoint linked to the initial
subflow is removed, and re-added with a different ID.

Note that removing the initial subflow will not decrement the 'subflows'
counters, which corresponds to the *additional* subflows. On the other
hand, when the same endpoint is re-added, it will increment this
counter, as it will be seen as an additional subflow this time.

The 'Fixes' tag here below is the same as the one from the previous
commit: this patch here is not fixing anything wrong in the selftests,
but it validates the previous fix for an issue introduced by this commit
ID.

43ca9a10d0 selftests: mptcp: join: check re-using ID of unused ADD_ADDR
[ Upstream commit a13d5aad4dd9a309eecdc33cfd75045bd5f376a3 ]

This test extends "delete re-add signal" to validate the previous
commit. An extra address is announced by the server, but this address
cannot be used by the client. The result is that no subflow will be
established to this address.

Later, the server will delete this extra endpoint, and set a new one,
with a valid address, but re-using the same ID. Before the previous
commit, the server would not have been able to announce this new
address.

While at it, extra checks have been added to validate the expected
numbers of MPJ, ADD_ADDR and RM_ADDR.

The 'Fixes' tag here below is the same as the one from the previous
commit: this patch here is not fixing anything wrong in the selftests,
but it validates the previous fix for an issue introduced by this commit
ID.
