In this configuration, if the class belongs to the other channel,
then all the queues must be bound again explicitly to the new class,
for the rate limit parameters on the other channel to take effect.

So, always explicitly bind all queues to the port rate limit traffic
class, regardless of the traffic management channel that it belongs
to. Also, only bind queues to port rate limit traffic class, if all

Pull thread fixes from Christian Brauner:
 "Here is an urgent fix for ptrace_may_access() permission checking.

  Commit 69f594a3 ("ptrace: do not audit capability check when
  outputing /proc/pid/stat") introduced the ability to opt out of audit
  messages for accesses to various proc files since they are not
  violations of policy.

  While doing so it switched the check from ns_capable() to
  has_ns_capability{_noaudit}(). That means it switched from checking
  the subjective credentials (ktask->cred) of the task to using the
  objective credentials (ktask->real_cred). This is appears to be wrong.
  ptrace_has_cap() is currently only used in ptrace_may_access() And is
  used to check whether the calling task (subject) has the
  CAP_SYS_PTRACE capability in the provided user namespace to operate on
  the target task (object). According to the cred.h comments this means
  the subjective credentials of the calling task need to be used.

  With this fix we switch ptrace_has_cap() to use security_capable() and
  thus back to using the subjective credentials.

  As one example where this might be particularly problematic, Jann
  pointed out that in combination with the upcoming IORING_OP_OPENAT{2}
  feature, this bug might allow unprivileged users to bypass the
  capability checks while asynchronously opening files like /proc/*/mem,
  because the capability checks for this would be performed against
  kernel credentials.

  To illustrate on the former point about this being exploitable: When
  io_uring creates a new context it records the subjective credentials
  of the caller. Later on, when it starts to do work it creates a kernel
  thread and registers a callback. The callback runs with kernel creds
  for ktask->real_cred and ktask->cred.

  To prevent this from becoming a full-blown 0-day io_uring will call
  override_cred() and override ktask->cred with the subjective
  credentials of the creator of the io_uring instance. With
  ptrace_has_cap() currently looking at ktask->real_cred this override
  will be ineffective and the caller will be able to open arbitray proc
  files as mentioned above.

  Luckily, this is currently not exploitable but would be so once
  IORING_OP_OPENAT{2} land in v5.6. Let's fix it now.

  To minimize potential regressions I successfully ran the criu
  testsuite. criu makes heavy use of ptrace() and extensively hits
  ptrace_may_access() codepaths and has a good change of detecting any
  regressions.

  Additionally, I succesfully ran the ptrace and seccomp kernel tests"

====================
bnxt_en: Bug fixes.

3 small bug fix patches.  The 1st two are aRFS fixes and the last one
fixes a fatal driver load failure on some kernels without PCIe
extended config space support enabled.

Please also queue these for -stable.  Thanks.

DSN read can fail, for example on a kdump kernel without PCIe extended
config space support.  If DSN read fails, don't set the
BNXT_FLAG_DSN_VALID flag and continue loading.  Check the flag
to see if the stored DSN is valid before using it.  Only VF reps
creation should fail without valid DSN.

Fix bnxt_fltr_match() to match ipv6 source and destination addresses.
The function currently only checks ipv4 addresses and will not work
corrently on ipv6 filters.

The NTUPLE related firmware commands are sent to the wrong firmware
channel, causing all these commands to fail on new firmware that
supports the new firmware channel.  Fix it by excluding the 3
NTUPLE firmware commands from the list for the new firmware channel.

Commit 69f594a3 ("ptrace: do not audit capability check when outputing /proc/pid/stat")
introduced the ability to opt out of audit messages for accesses to various
proc files since they are not violations of policy.  While doing so it
somehow switched the check from ns_capable() to
has_ns_capability{_noaudit}(). That means it switched from checking the
subjective credentials of the task to using the objective credentials. This
is wrong since. ptrace_has_cap() is currently only used in
ptrace_may_access() And is used to check whether the calling task (subject)
has the CAP_SYS_PTRACE capability in the provided user namespace to operate
on the target task (object). According to the cred.h comments this would
mean the subjective credentials of the calling task need to be used.
This switches ptrace_has_cap() to use security_capable(). Because we only
call ptrace_has_cap() in ptrace_may_access() and in there we already have a
stable reference to the calling task's creds under rcu_read_lock() there's
no need to go through another series of dereferences and rcu locking done
in ns_capable{_noaudit}().

As one example where this might be particularly problematic, Jann pointed
out that in combination with the upcoming IORING_OP_OPENAT feature, this
bug might allow unprivileged users to bypass the capability checks while
asynchronously opening files like /proc/*/mem, because the capability
checks for this would be performed against kernel credentials.

To illustrate on the former point about this being exploitable: When
io_uring creates a new context it records the subjective credentials of the
caller. Later on, when it starts to do work it creates a kernel thread and
registers a callback. The callback runs with kernel creds for
ktask->real_cred and ktask->cred. To prevent this from becoming a
full-blown 0-day io_uring will call override_cred() and override
ktask->cred with the subjective credentials of the creator of the io_uring
instance. With ptrace_has_cap() currently looking at ktask->real_cred this
override will be ineffective and the caller will be able to open arbitray
proc files as mentioned above.
Luckily, this is currently not exploitable but will turn into a 0-day once
IORING_OP_OPENAT{2} land in v5.6. Fix it now!
