====================
intel: use bitfield operations
Jesse Brandeburg says:
After repeatedly getting review comments on new patches, and sporadic
patches to fix parts of our drivers, we should just convert the Intel code
to use FIELD_PREP() and FIELD_GET(). It's then "common" in the code and
hopefully future change-sets will see the context and do-the-right-thing.
This conversion was done with a coccinelle script which is mentioned in the
commit messages. Generally there were only a couple conversions that were
"undone" after the automatic changes because they tried to convert a
non-contiguous mask.
Patch 1 is required at the beginning of this series to fix a "forever"
issue in the e1000e driver that fails the compilation test after conversion
because the shift / mask was out of range.
The second patch just adds all the new #includes in one go.
The patch titled: "ice: fix pre-shifted bit usage" is needed to allow the
use of the FIELD_* macros and fix up the unexpected "shifts included"
defines found while creating this series.
The rest are the conversion to use FIELD_PREP()/FIELD_GET(), and the
occasional leXX_{get,set,encode}_bits() call, as suggested by Alex.

Some drivers might misbehave if TSO packets get too big.
GVE for instance uses a 16bit field in its TX descriptor,
and will do bad things if a packet is bigger than 2^16 bytes.
Linux TCP stack honors dev->gso_max_size, but there are
other ways for too big packets to reach an ndo_start_xmit()
handler : virtio_net, af_packet, GRO...
Add a generic check in gso_features_check() and fallback
to GSO when needed.
gso_max_size was added in the blamed commit.

run_cmd_grep_fail should be used when expecting the cmd fail, or the ret
will be set to 1, and the total test return 1 when exiting. This would cause
the result report to fail if run via run_kselftest.sh.

GCC seems to incorrectly fail to evaluate skb_ext_total_length() at
compile time under certain conditions.
The issue even occurs if all values in skb_ext_type_len[] are "0",
ruling out the possibility of an actual overflow.
As the patch has been in mainline since v6.6 without triggering the
problem it seems to be a very uncommon occurrence.
As the issue only occurs when -fno-tree-loop-im is specified as part of
CFLAGS_GCOV, disable the BUILD_BUG_ON() only when building with coverage
reporting enabled.

Only the posix timer system calls use this (when the posix timer support
is disabled, which does not actually happen in any normal case), because
they had debug code to print out a warning about missing system calls.
Get rid of that special case, and just use the standard COND_SYSCALL
interface that creates weak system call stubs that return -ENOSYS for
when the system call does not exist.
This fixes a kCFI issue with the SYS_NI() hackery:

net: sched: Make tc-related drop reason more flexible for remaining qdiscs
This patch builds on Daniel's patch[1] to add initial support of tc drop
reason. The main goal is to distinguish between policy and error drops for
the remainder of the egress qdiscs (other than clsact).
The drop reason is set by cls_api and act_api in the tc skb cb in case
any error occurred in the data path.
Also add new skb drop reasons that are idiosyncratic to TC.
[1] https://lore.kernel.org/all/20231009092655.22025-1-daniel@iogearbox.net
Changes in V5:
- Drop "EXT_" from cookie error's drop reason name in doc
Changes in V4:
- Condense all the cookie drop reasons into one
Changes in V3:
- Removed duplicate assignment
- Rename function tc_skb_cb_drop_reason to tcf_get_drop_reason
- Move zone field upwards in struct tc_skb_cb to move hole to the end of
the struct
Changes in V2:
- Dropped RFC tag
- Removed check for drop reason being overwritten by filter in cls_api.c
- Simplified logic and removed function tcf_init_drop_reason

This adds support for the LED's on most chip versions. Excluded are
the old non-PCIe versions and RTL8125. RTL8125 has a different LED
register layout, support for it will follow later.
LED's can be controlled from userspace using the netdev LED trigger.
Tested on RTL8168h.
Note: The driver can't know which LED's are actually physically
wired. Therefore not every LED device may represent a physically
available LED.

====================
Add MDB bulk deletion support
This patchset adds MDB bulk deletion support, allowing user space to
request the deletion of matching entries instead of dumping the entire
MDB and issuing a separate deletion request for each matching entry.
Support is added in both the bridge and VXLAN drivers in a similar
fashion to the existing FDB bulk deletion support.
The parameters according to which bulk deletion can be performed are
similar to the FDB ones, namely: Destination port, VLAN ID, state (e.g.,
"permanent"), routing protocol, source / destination VNI, destination IP
and UDP port. Flushing based on flags (e.g., "offload", "fast_leave",
"added_by_star_ex", "blocked") is not currently supported, but can be
added in the future, if a use case arises.
Patch #1 adds a new uAPI attribute to allow specifying the state mask
according to which bulk deletion will be performed, if any.
Patch #2 adds a new policy according to which bulk deletion requests
(with 'NLM_F_BULK' flag set) will be parsed.
Patches #3-#4 add a new NDO for MDB bulk deletion and invoke it from the
rtnetlink code when a bulk deletion request is made.
Patches #5-#6 implement the MDB bulk deletion NDO in the bridge and
VXLAN drivers, respectively.
Patch #7 allows user space to issue MDB bulk deletion requests by no
longer rejecting the 'NLM_F_BULK' flag when it is set in 'RTM_DELMDB'
requests.
Patches #8-#9 add selftests for both drivers, for both good and bad
flows.

For MDB bulk delete we will need to validate 'MDBA_SET_ENTRY'
differently compared to regular delete. Specifically, allow the ifindex
to be zero (in case not filtering on bridge port) and force the address
to be zero as bulk delete based on address is not supported.
Do that by introducing a new policy and choosing the correct policy
based on the presence of the 'NLM_F_BULK' flag in the netlink message
header. Use nlmsg_parse() for strict validation.

When we fail to allocate because of insufficient open buckets, we don't
want to retry from the full set of devices - we just want to retry in
blocking mode.
But if the retry in blocking mode fails with a different error code, we
end up squashing the -BCH_ERR_open_buckets_empty error with an error
that makes us thing we won't be able to allocate (insufficient_devices)
- which is incorrect when we didn't try to allocate from the full set of
devices, and causes the write to fail.

While working on the ring buffer, I found one more bug with the timestamp
code, and the fix for this removed the need for the final 64-bit cmpxchg!
The ring buffer events hold a "delta" from the previous event. If it is
determined that the delta can not be calculated, it falls back to adding an
absolute timestamp value. The way to know if the delta can be used is via
two stored timestamps in the per-cpu buffer meta data:
before_stamp and write_stamp
The before_stamp is written by every event before it tries to allocate its
space on the ring buffer. The write_stamp is written after it allocates its
space and knows that nothing came in after it read the previous
before_stamp and write_stamp and the two matched.
A previous fix dd93942570 ("ring-buffer: Do not try to put back
write_stamp") removed putting back the write_stamp to match the
before_stamp so that the next event could use the delta, but races were
found where the two would match, but not be for of the previous event.
It was determined to allow the event reservation to not have a valid
write_stamp when it is finished, and this fixed a lot of races.
The last use of the 64-bit timestamp cmpxchg depended on the write_stamp
being valid after an interruption. But this is no longer the case, as if an
event is interrupted by a softirq that writes an event, and that event gets
interrupted by a hardirq or NMI and that writes an event, then the softirq
could finish its reservation without a valid write_stamp.
In the slow path of the event reservation, a delta can still be used if the
write_stamp is valid. Instead of using a cmpxchg against the write stamp,
the before_stamp needs to be read again to validate the write_stamp. The
cmpxchg is not needed.
This updates the slowpath to validate the write_stamp by comparing it to
the before_stamp and removes all rb_time_cmpxchg() as there are no more
users of that function.
The removal of the 32-bit updates of rb_time_t will be done in the next
merge window.

Pull tracing fix from Steven Rostedt:
"While working on the ring buffer, I found one more bug with the
timestamp code, and the fix for this removed the need for the final
64-bit cmpxchg!
The ring buffer events hold a "delta" from the previous event. If it
is determined that the delta can not be calculated, it falls back to
adding an absolute timestamp value. The way to know if the delta can
be used is via two stored timestamps in the per-cpu buffer meta data:
before_stamp and write_stamp
The before_stamp is written by every event before it tries to allocate
its space on the ring buffer. The write_stamp is written after it
allocates its space and knows that nothing came in after it read the
previous before_stamp and write_stamp and the two matched.
A previous fix dd93942570 ("ring-buffer: Do not try to put back
write_stamp") removed putting back the write_stamp to match the
before_stamp so that the next event could use the delta, but races
