Pull CXL (Compute Express Link) fixes from Dan Williams:
"A collection of CXL fixes.
The touch outside of drivers/cxl/ is for a helper that allocates
physical address space. Device hotplug tests showed that the driver
failed to utilize (skipped over) valid capacity when allocating a new
memory region. Outside of that, new tests uncovered a small crop of
lockdep reports.
There is also some miscellaneous error path and leak fixups that are
not urgent, but useful to cleanup now.

Check multiple keys on a socket:
- rotation on closed socket
- current/rnext operations shouldn't be possible on listen sockets
- current/rnext key set should be the one, that's used on connect()
- key rotations with pseudo-random generated keys
- copying matching keys on connect() and on accept()
At this moment there are 3 tests that are "expected" to fail: a kernel
fix is needed to improve the situation, they are marked XFAIL.

Check that a rare functionality of TCP named self-connect works with
TCP-AO. This "under the cover" also checks TCP simultaneous connect
(TCP_SYN_RECV socket state), which would be harder to check other ways.
In order to verify that it's indeed TCP simultaneous connect, check
the counters TCPChallengeACK and TCPSYNChallenge.

Check that both active and passive reset works and correctly sign
segments with TCP-AO or don't send RSTs if not possible to sign.
A listening socket with backlog = 0 gets one connection in accept
queue, another in syn queue. Once the server/listener socket is
forcibly closed, client sockets aren't connected to anything.
In regular situation they would receive RST on any segment, but
with TCP-AO as there's no listener, no AO-key and unknown ISNs,
no RST should be sent.
And "passive" reset, where RST is sent on reply for some segment
(tcp_v{4,6}_send_reset()) - there use TCP_REPAIR to corrupt SEQ numbers,
which later results in TCP-AO signed RST, which will be verified and
client socket will get EPIPE.
No TCPAORequired/TCPAOBad segments are expected during these tests.

The test plan is:
1. check that TCP-AO connection may be restored on another socket
2. check restore with wrong send/recv ISN (checking that they are

high bytes of it taken into MAC generation)

The test plan was (most of tests have all 3 client types):
1. TCP-AO listen (INADDR_ANY)
2. TCP-MD5 listen (INADDR_ANY)
3. non-signed listen (INADDR_ANY)
4. TCP-AO + TCP-MD5 listen (prefix)
5. TCP-AO subprefix add failure [checked in setsockopt-closed.c]
6. TCP-AO out of prefix connect [checked in connect-deny.c]
7. TCP-AO + TCP-MD5 on connect()
8. TCP-AO intersect with TCP-MD5 failure
9. Established TCP-AO: add TCP-MD5 key
10. Established TCP-MD5: add TCP-AO key
11. Established non-signed: add TCP-AO key

Provide functions to create selftests dedicated to TCP-AO.
They can run in parallel, as they use temporary net namespaces.
They can be very specific to the feature being tested.
This will allow to create a lot of TCP-AO tests, without complicating
one binary with many --options and to create scenarios, that are
hard to put in bash script that uses one binary.

Since libbpf v1.0, libbpf doesn't return error code embedded into the
pointer iteself, libbpf_get_error() is deprecated and it is basically
the same as using -errno directly.
So replace the invocations of libbpf_get_error() by -errno in
kprobe_multi_test. For libbpf_get_error() in test_attach_api_fails(),
saving -errno before invoking ASSERT_xx() macros just in case that
errno is overwritten by these macros. However, the invocation of
libbpf_get_error() in get_syms() should be kept intact, because
hashmap__new() still returns a pointer with embedded error code.

Greg lamented:
"Ick, sorry about that, obviously this test isn't actually built by any
bots :("
A quick and dirty way to prevent this problem going forward is to always
compile ndtest.ko whenever nfit_test is built. While this still does not
expose the test code to any of the known build bots, it at least makes
it the case that anyone that runs the x86 tests also compiles the
powerpc test.
I.e. the Intel NVDIMM maintainers are less likely to fall into this hole
in the future.

Add a global variable NS_LIST to store all the namespaces that setup_ns
created, so the caller could call cleanup_all_ns() instead of remember
all the netns names when using cleanup_ns().

vmlinux.h declarations are more ergnomic, especially when working with
kfuncs. The uapi headers are often incomplete for kfunc definitions.
This commit also switches bitfield accesses to use CO-RE helpers.
Switching to vmlinux.h definitions makes the verifier very
unhappy with raw bitfield accesses. The error is:
; md.u.md2.dir = direction;
33: (69) r1 = *(u16 *)(r2 +11)
misaligned stack access off (0x0; 0x0)+-64+11 size 2
Fix by using CO-RE-aware bitfield reads and writes.

With previous patch, one of subtests in test_btf_id becomes
flaky and may fail. The following is a failing example:
Error: #26 btf
Error: #26/174 btf/BTF ID
Error: #26/174 btf/BTF ID
btf_raw_create:PASS:check 0 nsec
btf_raw_create:PASS:check 0 nsec
test_btf_id:PASS:check 0 nsec
...
test_btf_id:PASS:check 0 nsec
test_btf_id:FAIL:check BTF lingersdo_test_get_info:FAIL:check failed: -1
The test tries to prove a btf_id not available after the map is closed.
But btf_id is freed only after workqueue and a rcu grace period, compared
to previous case just after a rcu grade period.
Depending on system workload, workqueue could take quite some time
to execute function bpf_map_free_deferred() which may cause the test failure.
Instead of adding arbitrary delays, let us remove the logic to
check btf_id availability after map is closed.

Fix test broken by shared umem test and framework enhancement commit.
Correct the current implementation of pkt_stream_replace_half() by
ensuring that nb_valid_entries are not set to half, as this is not true
for all the tests. Ensure that the expected value for valid_entries for
the SEND_RECEIVE_UNALIGNED test equals the total number of packets sent,
which is 4096.
Create a new function called pkt_stream_pkt_set() that allows for packet
modification to meet specific requirements while ensuring the accurate
maintenance of the valid packet count to prevent inconsistencies in packet
tracking.

Verify, whether VLAN tag and proto are set correctly.
To simulate "stripped" VLAN tag on veth, send test packet from VLAN
interface.
Also, add TO_STR() macro for convenience.

The easiest way to simulate stripped VLAN tag in veth is to send a packet
from VLAN interface, attached to veth. Unfortunately, this approach is
incompatible with AF_XDP on TX side, because VLAN interfaces do not have
such feature.
Check both packets sent via AF_XDP TX and regular socket.
AF_INET packet will also have a filled-in hash type (XDP_RSS_TYPE_L4),
unlike AF_XDP packet, so more values can be checked.
