Linus Torvalds 697fa9b586 sound fixes for 6.4-rc6
Lots of small fixes, and almost all are device-specific.
 A few of them are the fixes for the old regressions by the fast
 kctl lookups (introduced around 5.19).  Others are ASoC simple-card
 fixes, selftest compile warning fixes, ASoC AMD quirks, various
 ASoC codec fixes as well as usual HD-audio quirks.

Yonghong Song 69844e335d selftests/bpf: Fix sockopt_sk selftest
Commit f4e4534850 ("net/netlink: fix NETLINK_LIST_MEMBERSHIPS length report")
fixed NETLINK_LIST_MEMBERSHIPS length report which caused
selftest sockopt_sk failure. The failure log looks like

  test_sockopt_sk:PASS:join_cgroup /sockopt_sk 0 nsec
  run_test:PASS:skel_load 0 nsec
  run_test:PASS:setsockopt_link 0 nsec
  run_test:PASS:getsockopt_link 0 nsec
  getsetsockopt:FAIL:Unexpected NETLINK_LIST_MEMBERSHIPS value unexpected Unexpected NETLINK_LIST_MEMBERSHIPS value: actual 8 != expected 4
  run_test:PASS:getsetsockopt 0 nsec
  #201     sockopt_sk:FAIL

In net/netlink/af_netlink.c, function netlink_getsockopt(), for NETLINK_LIST_MEMBERSHIPS,
nlk->ngroups equals to 36. Before Commit f4e4534850, the optlen is calculated as
  ALIGN(nlk->ngroups / 8, sizeof(u32)) = 4
After that commit, the optlen is
  ALIGN(BITS_TO_BYTES(nlk->ngroups), sizeof(u32)) = 8

Fix the test by setting the expected optlen to be 8.

To align with what is done by the in-kernel PM, update userspace pm
subflow selftests, by sending the a remove_addrs command together
before the remove_subflows command. This will get a RM_ADDR in
chk_rm_nr().

Masami Hiramatsu (Google) eb50d0f250 selftests/ftrace: Choose target function for filter test from samples
Since the event-filter-function.tc expects the 'exit_mmap()' directly
calls 'kmem_cache_free()', this is vulnerable to code modifications.

Choose the target function for the filter test from the sample
event data so that it can keep test running correctly even if the caller
function name will be changed.

Michal Luczaj 47d2804bc9 KVM: selftests: Add test for race in kvm_recalculate_apic_map()
Keep switching between LAPIC_MODE_X2APIC and LAPIC_MODE_DISABLED during
APIC map construction to hunt for TOCTOU bugs in KVM.  KVM's optimized map
recalc makes multiple passes over the list of vCPUs, and the calculations
ignore vCPU's whose APIC is hardware-disabled, i.e. there's a window where
toggling LAPIC_MODE_DISABLED is quite interesting.

Matthieu Baerts d328fe8706 selftests: mptcp: join: avoid using 'cmp --bytes'
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.

Linus Torvalds 8b817fded4 Tracing fixes:
User events:
 
  - Use long instead of int for storing the enable set/clear bit, as it was
    found that big endian machines could end up using the wrong bits.
 
  - Split allocating mm and attaching it. This keeps the allocation separate
    from the registration and avoids various races.
 
  - Remove RCU locking around pin_user_pages_remote() as that can schedule. The
    RCU protection is no longer needed with the above split of mm allocation and
    attaching.
 
  - Rename the "link" fields of the various structs to something more
    meaningful.
 
  - Add comments around user_event_mm struct usage and locking requirements.
 
 Timerlat tracer:
 
  - Fix missed wakeup of timerlat thread caused by the timerlat interrupt
    triggering when tracing is off. The timer interrupt handler needs to always
    wake up the timerlat thread regardless if tracing is enabled or not,
    otherwise, it will never wake up.
 
 Histograms:
 
  - Fix regression of breaking the "stacktrace" modifier for variables. That
    modifier cannot be used for values, but can be used for variables that are
    passed from one histogram to the next. This was broken when adding the
    restriction to values as the variable logic used the same code.
 
  - Rename the special field "stacktrace" to "common_stacktrace". Special fields
    (that are not actually part of the event, but can act just like event
    fields, like 'comm' and 'timestamp') should be prefixed with 'common_' for
    consistency. To keep backward compatibility, 'stacktrace' can still be used
    (as with the special field 'cpu'), but can be overridden if the event has a
    field called 'stacktrace'.
 
  - Update the synthetic event selftests to use the new name (synthetic events
    are created by histograms)
 
 Tracing bootup selftests:
 
  - Reorganize the code to keep artifacts of the selftests not compiled in when
    selftests are not configured.
 
  - Add various cond_resched() around the selftest code, as the softlock
    watchdog was triggering much more often. It appears that the kernel runs
    slower now with full debugging enabled.
 
  - While debugging ftrace with ftrace (using an instance ring buffer instead of
    the top level one), I found that the selftests were disabling prints to the
    debug instance. This should not happen, as the selftests only disable
    printing to the main buffer as the selftests examine the main buffer to see
    if it has what it expects, and prints can make the tests fail. Make the
    selftests only disable printing to the toplevel buffer, and leave the
    instance buffers alone.

With the rename of the stacktrace field to common_stacktrace, update the
selftests to reflect this change. Copy the current selftest to test the
backward compatibility "stacktrace" keyword. Also the "requires" of that
test was incorrect, so it would never actually ran before. That is fixed
now.

To fix simply remove the err value because its not actually used anywhere
in the testing. We can investigate the root cause later. Future patch should
probably actually test the err value as well. Although if the map updates
fail they will get caught eventually by userspace.

John Fastabend 80e24d2226 bpf, sockmap: Test FIONREAD returns correct bytes in rx buffer with drops
When BPF program drops pkts the sockmap logic 'eats' the packet and
updates copied_seq. In the PASS case where the sk_buff is accepted
we update copied_seq from recvmsg path so we need a new test to
handle the drop case.

Original patch series broke this resulting in

test_sockmap_skb_verdict_fionread:PASS:ioctl(FIONREAD) error 0 nsec
test_sockmap_skb_verdict_fionread:FAIL:ioctl(FIONREAD) unexpected ioctl(FIONREAD): actual 1503041772 != expected 256

After updated patch with fix.

John Fastabend bb516f98c7 bpf, sockmap: Test FIONREAD returns correct bytes in rx buffer
A bug was reported where ioctl(FIONREAD) returned zero even though the
socket with a SK_SKB verdict program attached had bytes in the msg
queue. The result is programs may hang or more likely try to recover,
but use suboptimal buffer sizes.

Add a test to check that ioctl(FIONREAD) returns the correct number of
bytes.

Po-Hsu Lin d226b1df36 selftests: fib_tests: mute cleanup error message
In the end of the test, there will be an error message induced by the
`ip netns del ns1` command in cleanup()

  Tests passed: 201
  Tests failed:   0
  Cannot remove namespace file "/run/netns/ns1": No such file or directory

This can even be reproduced with just `./fib_tests.sh -h` as we're
calling cleanup() on exit.

Redirect the error message to /dev/null to mute it.

V2: Update commit message and fixes tag.
V3: resubmit due to missing netdev ML in V2

Dave Jiang e764f12208 cxl: Move cxl_await_media_ready() to before capacity info retrieval
Move cxl_await_media_ready() to cxl_pci probe before driver starts issuing
IDENTIFY and retrieving memory device information to ensure that the
device is ready to provide the information. Allow cxl_pci_probe() to succeed
even if media is not ready. Cache the media failure in cxlds and don't ask
the device for any media information.

The rationale for proceeding in the !media_ready case is to allow for
mailbox operations to interrogate and/or remediate the device. After
media is repaired then rebinding the cxl_pci driver is expected to
restart the capacity scan.

Dan Williams eb0764b822 cxl/port: Enable the HDM decoder capability for switch ports
Derick noticed, when testing hot plug, that hot-add behaves nominally
after a removal. However, if the hot-add is done without a prior
removal, CXL.mem accesses fail. It turns out that the original
implementation of the port driver and region programming wrongly assumed
that platform-firmware always enables the host-bridge HDM decoder
capability. Add support turning on switch-level HDM decoders in the case
where platform-firmware has not.

The implementation is careful to only arrange for the enable to be
undone if the current instance of the driver was the one that did the
enable. This is to interoperate with platform-firmware that may expect
CXL.mem to remain active after the driver is shutdown. This comes at the
cost of potentially not shutting down the enable on kexec flows, but it
is mitigated by the fact that the related HDM decoders still need to be
enabled on an individual basis.

Andrea Mayer f97b8401e0 selftets: seg6: disable rp_filter by default in srv6_end_dt4_l3vpn_test
On some distributions, the rp_filter is automatically set (=1) by
default on a netdev basis (also on VRFs).
In an SRv6 End.DT4 behavior, decapsulated IPv4 packets are routed using
the table associated with the VRF bound to that tunnel. During lookup
operations, the rp_filter can lead to packet loss when activated on the
VRF.
Therefore, we chose to make this selftest more robust by explicitly
disabling the rp_filter during tests (as it is automatically set by some
Linux distributions).

Andrea Mayer 21a933c79a selftests: seg6: disable DAD on IPv6 router cfg for srv6_end_dt4_l3vpn_test
The srv6_end_dt4_l3vpn_test instantiates a virtual network consisting of
several routers (rt-1, rt-2) and hosts.
When the IPv6 addresses of rt-{1,2} routers are configured, the Deduplicate
Address Detection (DAD) kicks in when enabled in the Linux distros running
the selftests. DAD is used to check whether an IPv6 address is already
assigned in a network. Such a mechanism consists of sending an ICMPv6 Echo
Request and waiting for a reply.
As the DAD process could take too long to complete, it may cause the
failing of some tests carried out by the srv6_end_dt4_l3vpn_test script.

To make the srv6_end_dt4_l3vpn_test more robust, we disable DAD on routers
since we configure the virtual network manually and do not need any address
deduplication mechanism at all.

Florian Westphal 3acf8f6c14 selftests: nft_flowtable.sh: check ingress/egress chain too
Make sure flowtable interacts correctly with ingress and egress
chains, i.e. those get handled before and after flow table respectively.

Adds three more tests:
1. repeat flowtable test, but with 'ip dscp set cs3' done in
   inet forward chain.

Expect that some packets have been mangled (before flowtable offload
became effective) while some pass without mangling (after offload
succeeds).

2. repeat flowtable test, but with 'ip dscp set cs3' done in
   veth0:ingress.

Expect that all packets pass with cs3 dscp field.

3. same as 2, but use veth1:egress.  Expect the same outcome.
