ip6gre tunnels are tested in the test_tunnel.sh but not in the test_progs
framework.
Add a new test in test_progs to test ip6gre tunnels. It uses the same
network topology and the same BPF programs than the script. Disable the
IPv6 DAD feature because it can take lot of time and cause some tests to
fail depending on the environment they're run on.
Remove test_ip6gre() and test_ip6gretap() from the script.

All tests use more or less the same ping commands as final validation.
Also test_ping()'s return value is checked with ASSERT_OK() while this
check is already done by the SYS() macro inside test_ping().
Create helpers around test_ping() and use them in the tests to avoid code
duplication.
Remove the unnecessary ASSERT_OK() from the tests.

Add tests for rejecting sleepable and accepting non-sleepable global
function calls in atomic contexts. For spin locks, we still reject
all global function calls. Once resilient spin locks land, we will
carefully lift in cases where we deem it safe.

In a nvdimm interleave-set each device with an invalid or zero
serial number may cause pmem region initialization to fail, but in
cxl case such device could still set cookies of nd_interleave_set
and create a nvdimm pmem region.
This adds the validation of serial number in cxl pmem region creation.
The event of no serial number would cause to fail to set the cookie
and pmem region.
For cxl-test to work properly, always +1 on mock device's serial
number.

When PCIe AER is in FW-First, OS should process CXL Protocol errors from
CPER records. Introduce support for handling and logging CXL Protocol
errors.
The defined trace events cxl_aer_uncorrectable_error and
cxl_aer_correctable_error trace native CXL AER endpoint errors. Reuse them
to trace FW-First Protocol errors.
Since the CXL code is required to be called from process context and
GHES is in interrupt context, use workqueues for processing.
Similar to CXL CPER event handling, use kfifo to handle errors as it
simplifies queue processing by providing lock free fifo operations.
Add the ability for the CXL sub-system to register a workqueue to
process CXL CPER protocol errors.

After the recent merge between net-next and net, I got some conflicts on
my side because the merge resolution was different from Stephen's one
[1] I applied on my side in the MPTCP tree.
It looks like the code that is now in net-next is using the old way to
retrieve the local and remote addresses. This patch is now using the new
way, like what was in Stephen's email [1].
Also, in get_interface_info(), there were no conflicts in this area,
because that was new code from 'net', but a small adaptation was needed
there as well to get the remote address.

2) Skip several tests in case kernel is tainted, otherwise tests bogusly
report failure too as they also check for tainted kernel,
from Florian Westphal.
3) Fix a hyphothetical integer overflow in do_ip_vs_get_ctl() leading
to bogus error logs, from Dan Carpenter.
4) Fix incorrect offset in ipv4 option match in nft_exthdr, from

Commit 51bef03e1a ("selftests/net: deflake GRO tests") recently
switched to NAPI suspension, and lowered the timeout from 1ms to 100us.
This started causing flakes in netdev-run CI. Let's bump it to 200us.
In a quick test of a debug kernel I see failures with 100us, with 200us
in 5 runs I see 2 completely clean runs and 3 with a single retry
(GRO test will retry up to 5 times).

These scripts fail if the kernel is tainted which leads to wrong test
failure reports in CI environments when an unrelated test triggers some

Check taint state at start of script and SKIP if its already dodgy.

Adding the aligned(1024) attribute to the definition of __rseq_abi did
not increase its size to 1024, for this attribute to impact the size of
__rseq_abi it would need to be added to the declaration of 'struct
rseq_abi'. We only want to increase the size of the TLS allocation to
ensure registration will succeed with future extended ABI. Use a union
with a dummy member to ensure we allocate 1024 bytes.
