ixgbe: Restore EEE exclusion for X550EM_X KR
X550EM_X KR devices do not support EEE and have no setup_eee operation.
The shared-code update restored the capability removed by d61b6a41dd30,
and the E610 EEE support subsequently added an unchecked call during
attach. Together these changes allow a NULL function pointer call when
attaching a KR device.
Remove the incorrect EEE capability and use the NULL-safe ixgbe_setup_eee()
wrapper when enabling EEE at attach.
Removing the unsupported capability also stops exposing eee_state and the
eee.tx_lpi_count and eee.rx_lpi_count sysctls on X550EM_X_KR devices.

bsnmp: zero-fill the destination on a short ASN.1 IpAddress
asn_get_ipaddress_raw() meant to pad the 4-byte buffer after a short
copy, but the loop bound was the already-reached len and never ran,
leaving addr[len..3] uninitialised. Pad to 4.
This is harmless for the in-tree consumers (bsnmpd(1) and
libbsnmpclient) which zero the PDU before decoding it.

esp: Allocate the crypto request and its callback state together
esp_input() and esp_output() allocated a cryptop from the crypto layer,
then malloc'ed the xform_data the callback needs, and with ESN a third
buffer for the separate AAD. The callback freed all three. That is
two or three allocation pairs for every packet.
Put the three in one structure, allocated once per packet from a
dedicated UMA zone. The crypto layer provides crypto_initreq() and
crypto_destroyreq() for an embedded cryptop, as wg(4) and ktls use.
The AAD buffer is sized for the ESP header, the longest IV and the
high-order half of the sequence number, which is all the separate AAD
can hold.
No functional change intended.

carp: Check if_carp under carp_sx in carp_nl_get()
carp_nl_get() tested ifp->if_carp for NULL before taking carp_sx and
walked the softc list afterwards. When the last vhid on the interface
is removed in between, carp_free_if() clears if_carp and the walk
dereferences a NULL pointer. A reader that passes the check while the

linux: Bound native getdents and getdents64 batches
linux_getdents() and linux_getdents64() round their native read size up
to DEV_BSIZE before converting entries. For an unaligned caller buffer,
the native batch can contain more entries than fit in the Linux buffer.
Conversion then returns EINVAL even after copying complete entries,
and the native read has already advanced the directory position.
For counts of at least DEV_BSIZE, use min(args->count, MAXBSIZE) instead.
A 768-byte request, such as rustix's initial directory read, now uses a
768-byte native buffer rather than 1024. The converted Linux dirent and
dirent64 records are no larger than their native counterparts, so the
whole translated batch fits. Returning a short batch is allowed, and
consuming the whole native batch avoids needing to rewind the directory
position.
Keep the existing sizing for counts below DEV_BSIZE. This fixes the
oversized-batch case in both getdents interfaces, including legacy
getdents for 32-bit and 64-bit callers. The remaining small-buffer,

cd9660: Fix dereferencing invalid RR outlen ptr
`ISO_RRIP_ANALYZE` is constructed in four places. Two of the
initializers set the `outlen` field while the other two,
`cd9660_rrip_analyze` and `cd9660_rrip_offset`, leave it uninitialized.
The uninitialized paths can dereference an invalid pointer on error
paths which causes a kernel panic.
To fix, I zero out `ISO_RRIP_ANALYZE` in all four places where it's
initialized and check that `outlen` is non-null on the error path
in `cd9660_rrip_loop`.
While testing the above, I encountered another kernel panic due to
mounting continuing after the error branch. Evidently, the ISO continued
mounting through the normal ISO 9660 path then triggered a panic down
the line due to a very broken file system from the ISO. To fix that, I
propagate the error from the RR path then fail in the mount path.

sysvmsg: Fix sequence number wraparound races
The SysV message queue code has the same problem that we fixed in the
semaphore code in SA-26:54.sysvsem and SA-26:64.sysvsem. That is,
kern_msgrcv() and kern_msgsnd() are susceptible to TOCTOU races when
they sleep waiting for messages and queue space, respectively. Unlike
the semaphore code, however, the message queue array is never resized
and there is no notion of message queue sets, so such races do not open
up any memory safety bugs.
Fix the races, following the pattern from the SysV semaphore changes:
use a global sequence number array with wide counters, to avoid changing
the KBI which is embedded in userspace tools. Fix kern_msgsnd(), which
did not validate the sequence number at all after sleeping. Use a
msgvalid() helper to factor out some duplicated checks. Convert a
couple of local flag variables to bools.
