The recent move of this script from scripts/ to tools/docs/
did not account for the 'cd' directory usage.
Update "cd .." to "cd ../.." to make the script self-correcting.
This also eliminates a shell warning:

Inline kernel-doc blocks failed to parse tags containing dots (e.g.
creator.process_name in panfrost_gem.h) because the @name regex only
matched word characters. Modify the single-line pattern to match
doc_inline_sect so it includes \. and parses the same as a multi-line
comment.

Specially on kAPI, sometimes it is desirable to be able to
describe global variables that are part of kAPI.
Documenting vars with Sphinx is simple, as we don't need
to parse a data struct. All we need is the variable
declaration and use native C domain ::c:var: to format it
for us.
Add support for it.

Merge tag 'kvm-x86-fixes-6.19-rc1' of https://github.com/kvm-x86/linux into HEAD
KVM fixes for 6.19-rc1
- Add a missing "break" to fix param parsing in the rseq selftest.
- Apply runtime updates to the _current_ CPUID when userspace is setting
CPUID, e.g. as part of vCPU hotplug, to fix a false positive and to avoid
dropping the pending update.
- Disallow toggling KVM_MEM_GUEST_MEMFD on an existing memslot, as it's not
supported by KVM and leads to a use-after-free due to KVM failing to unbind
the memslot from the previously-associated guest_memfd instance.
- Harden against similar KVM_MEM_GUEST_MEMFD goofs, and prepare for supporting
flags-only changes on KVM_MEM_GUEST_MEMFD memlslots, e.g. for dirty logging.
- Set exit_code[63:32] to -1 (all 0xffs) when synthesizing a nested
SVM_EXIT_ERR (a.k.a. VMEXIT_INVALID) #VMEXIT, as VMEXIT_INVALID is defined
as -1ull (a 64-bit value).
- Update SVI when activating APICv to fix a bug where a post-activation EOI
for an in-service IRQ would effective be lost due to SVI being stale.
- Immediately refresh APICv controls (if necessary) on a nested VM-Exit
instead of deferring the update via KVM_REQ_APICV_UPDATE, as the request is
effectively ignored because KVM thinks the vCPU already has the correct
APICv settings.
Add a test case that reproduces deadlock scenario where the user has
a drr qdisc attached to root and has a mirred action that redirects to
self on egress

The ublk device will be created with all the requested feature flags,
however kublk will only use one of the modes to interact with request

The functions ublk_queue_use_zc(), ublk_queue_use_auto_zc(), and
ublk_queue_auto_zc_fallback() were returning int, but performing
bitwise AND on q->flags which is __u64.
When a flag bit is set in the upper 32 bits (beyond INT_MAX), the
result of the bitwise AND operation could overflow when cast to int,
leading to incorrect boolean evaluation.
For example, if UBLKS_Q_AUTO_BUF_REG_FALLBACK is 0x8000000000000000:
- (u64)flags & 0x8000000000000000 = 0x8000000000000000
- Cast to int: undefined behavior / incorrect value
- Used in if(): may evaluate incorrectly
Fix by:
1. Changing return type from int to bool for semantic correctness
2. Using !! to explicitly convert to boolean (0 or 1)
This ensures the functions return proper boolean values regardless
of which bit position the flags occupy in the 64-bit field.

Jakub reports spurious failures of the 'conntrack_reverse_clash.sh'
selftest. A bogus test makes nat core resort to port rewrite even
though there is no need for this.
When the test is made, nf_nat_used_tuple() would already have caused us
to return if no other CPU had added a colliding entry.
Moreover, nf_nat_used_tuple() would have ignored the colliding entry if
their origin tuples had been the same.
All that is left to check is if the colliding entry in the hash table
is subject to NAT, and, if its not, if our entry matches in the reverse
direction, e.g. hash table has
addr1:1234 -> addr2:80, and we want to commit
addr2:80 -> addr1:1234.
Because we already checked that neither the new nor the committed entry is
subject to NAT we only have to check origin vs. reply tuple:
for non-nat entries, the reply tuple is always the inverted original.
Just in case there are more problems extend the error reporting
in the selftest while at it and dump conntrack table/stats on error.

This test runs an overlay traffic, forwarded over a multicast-routed VXLAN
underlay. In order to determine whether packets reach their intended
destination, it uses a TC match. For convenience, it uses a flower match,
which however does not allow matching on the encapsulated packet. So
various service traffic ends up being indistinguishable from the test
packets, and ends up confusing the test. To alleviate the problem, the test
uses sleep to allow the necessary service traffic to run and clear the
channel, before running the test traffic. This worked for a while, but
lately we have nevertheless seen flakiness of the test in the CI.
Fix the issue by using u32 to match the encapsulated packet as well. The
confusing packets seem to always be IPv6 multicast listener reports.
Realistically they could be ARP or other ICMP6 traffic as well. Therefore
look for ethertype IPv4 in the IPv4 traffic test, and for IPv6 / UDP
combination in the IPv6 traffic test.

Flower is commonly used to match on packets in many bash-based selftests.

"qlen": 0
}
}

The JQ query in the helper function tc_rule_stats_get() assumes this form
and looks for the second element of the array.
However, a dump of a u32 filter looks like this:
[
{
"protocol": "all",
"pref": 49151,
"kind": "u32",
"chain": 0
},
{
"protocol": "all",
"pref": 49151,

"drops": 0,
"overlimits": 0,
"requeues": 0,
"backlog": 0,
"qlen": 0
}
}
]
}
},
]
There's an extra element which the JQ query ends up choosing.
Instead of hard-coding a particular index, look for the entry on which a
selector .options.actions yields anything.

The kernel is now built with -fms-extensions. Anonymous structs or
unions permitted by these extensions have been used in several places,
and can end up in the generated vmlinux.h file, for example:
struct ns_tree {
[...]
};
[...]
struct ns_common {
[...]
union {
struct ns_tree;
struct callback_head ns_rcu;
};
};
Trying to include this header for compiling a tool may result in build
warnings, if the compiler does not expect these extensions. This is the
case, for example, with bpftool:
In file included from skeleton/pid_iter.bpf.c:3:
.../tools/testing/selftests/bpf/tools/build/bpftool/vmlinux.h:64057:3:
warning: declaration does not declare anything
[-Wmissing-declarations]
64057 | struct ns_tree;
| ^~~~~~~~~~~~~~
Fix these build warnings in bpftool by turning on Microsoft extensions
when compiling the two BPF programs that rely on vmlinux.h.

This validates the previous commit: the userspace can set unknown flags
-- the 7th bit is currently unused -- without errors, but only the
supported ones are printed in the endpoints dumps.
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.

The wireguard YNL conversion was missing the customary .deps entry.
NIPA doesn't catch this but my CentOS 9 system complains:
wireguard-user.c:72:10: error: ‘WGALLOWEDIP_A_FLAGS’ undeclared here
wireguard-user.c:58:67: error: parameter 1 (‘value’) has incomplete type
58 | const char *wireguard_wgallowedip_flags_str(enum wgallowedip_flag value)
| ~~~~~~~~~~~~~~~~~~~~~~^~~~~
And similarly does Ubuntu 22.04.
One extra complication here is that we renamed the header guard,
so we need to compat with both old and new guard define.
