When userspace wants to send a non-DATA record (via the
TLS_SET_RECORD_TYPE cmsg), we need to send any pending data from a
previous MSG_MORE send() as a separate DATA record. If that DATA record
is encrypted asynchronously, tls_handle_open_record will return
-EINPROGRESS. This is currently treated as an error by
tls_process_cmsg, and it will skip setting record_type to the correct
value, but the caller (tls_sw_sendmsg_locked) handles that return
value correctly and proceeds with sending the new message with an
incorrect record_type (DATA instead of whatever was requested in the
cmsg).
Always set record_type before handling the open record. If
tls_handle_open_record returns an error, record_type will be
ignored. If it succeeds, whether with synchronous crypto (returning 0)
or asynchronous (returning -EINPROGRESS), the caller will proceed
correctly.

If we hit an error during the main loop of tls_sw_sendmsg_locked (eg
failed allocation), we jump to send_end and immediately
return. Previous iterations may have queued async encryption requests
that are still pending. We should wait for those before returning, as
we could otherwise be reading from memory that userspace believes
we're not using anymore, which would be a sort of use-after-free.
This is similar to what tls_sw_recvmsg already does: failures during
the main loop jump to the "wait for async" code, not straight to the
unlock/return.

During tls_sw_sendmsg_locked, we pre-allocate the encrypted message
for the size we're expecting to send during the current iteration, but
we may end up sending less, for example when splicing: if we're
getting the data from small fragments of memory, we may fill up all
the slots in the skmsg with less data than expected.
In this case, we need to trim the encrypted message to only the length
we actually need, to avoid pushing uninitialized bytes down the
underlying TCP socket.

Neal reported that using neper tcp_stream with TCP_TX_DELAY
set to 50ms would often lead to flows stuck in a small cwnd mode,
regardless of the congestion control.
While tcp_stream sets TCP_TX_DELAY too late after the connect(),
it highlighted two kernel bugs.
The following heuristic in tcp_tso_should_defer() seems wrong
for large RTT:
delta = tp->tcp_clock_cache - head->tstamp;
/* If next ACK is likely to come too late (half srtt), do not defer */
if ((s64)(delta - (u64)NSEC_PER_USEC * (tp->srtt_us >> 4)) < 0)
goto send_now;
If next ACK is expected to come in more than 1 ms, we should
not defer because we prefer a smooth ACK clocking.
While blamed commit was a step in the good direction, it was not
generic enough.
Another patch fixing TCP_TX_DELAY for established flows
will be proposed when net-next reopens.

Intel Wired LAN Driver Updates 2025-10-01 (idpf, ixgbe, ixgbevf)
For idpf:
Milena fixes a memory leak in the idpf reset logic when the driver resets
with an outstanding Tx timestamp.
For ixgbe and ixgbevf:
Jedrzej fixes an issue with reporting link speed on E610 VFs.
Jedrzej also fixes the VF mailbox API incompatibilities caused by the
confusion with API v1.4, v1.5, and v1.6. The v1.4 API introduced IPSEC
offload, but this was only supported on Linux hosts. The v1.5 API
introduced a new mailbox API which is necessary to resolve issues on ESX
hosts. The v1.6 API introduced a new link management API for E610. Jedrzej
introduces a new v1.7 API with a feature negotiation which enables properly
checking if features such as IPSEC or the ESX mailbox APIs are supported.
This resolves issues with compatibility on different hosts, and aligns the
API across hosts instead of having Linux require custom mailbox API
versions for IPSEC offload.
Koichiro fixes a KASAN use-after-free bug in ixgbe_remove().

There was backward compatibility in the terms of mailbox API. Various
drivers from various OSes supporting 10G adapters from Intel portfolio
could easily negotiate mailbox API.
This convention has been broken since introducing API 1.4.
Commit 0062e7cc95 ("ixgbevf: add VF IPsec offload code") added support
for IPSec which is specific only for the kernel ixgbe driver. None of the
rest of the Intel 10G PF/VF drivers supports it. And actually lack of
support was not included in the IPSec implementation - there were no such
code paths. No possibility to negotiate support for the feature was
introduced along with introduction of the feature itself.
Commit 339f289641 ("ixgbevf: Add support for new mailbox communication
between PF and VF") increasing API version to 1.5 did the same - it
introduced code supported specifically by the PF ESX driver. It altered API
version for the VF driver in the same time not touching the version
defined for the PF ixgbe driver. It led to additional discrepancies,
as the code provided within API 1.6 cannot be supported for Linux ixgbe
driver as it causes crashes.
The issue was noticed some time ago and mitigated by Jake within the commit
d0725312ad ("ixgbevf: stop attempting IPSEC offload on Mailbox API 1.5").
As a result we have regression for IPsec support and after increasing API
to version 1.6 ixgbevf driver stopped to support ESX MBX.
To fix this mess add new mailbox op asking PF driver about supported
features. Basing on a response determine whether to set support for IPSec
and ESX-specific enhanced mailbox.
New mailbox op, for compatibility purposes, must be added within new API
revision, as API version of OOT PF & VF drivers is already increased to
1.6 and doesn't incorporate features negotiate op.
Features negotiation mechanism gives possibility to be extended with new
features when needed in the future.

The function lan78xx_write_raw_eeprom failed to properly propagate EEPROM
write timeout errors (-ETIMEDOUT). In the timeout fallthrough path, it first
attempted to restore the pin configuration for LED outputs and then
returned only the status of that restore operation, discarding the
original timeout error saved in ret.
As a result, callers could mistakenly treat EEPROM write operation as
successful even though the EEPROM write had actually timed out with no
or partial data write.
To fix this, handle errors in restoring the LED pin configuration separately.
If the restore succeeds, return any prior EEPROM write timeout error saved
in ret to the caller.

eth: fbnic: fix XDP_TX and XDP vs qstats
Fix XDP_TX hangs and adjust the XDP statistics to match the definition
of qstats. The three problems are somewhat distinct.
XDP_TX hangs is a simple coding bug (patch 1).
The accounting of XDP packets is all over the place. Fix it to obey
qstat rules (packets seen by XDP always counted as Rx packets).
Patch 2 fixes the basic accounting, patch 3 touches up saving
the stats when rings are freed.
Patch 6 corrects reporting of alloc_fail stats which prevented
the pp_alloc_fail test from passing.
Patches 4, 5, 7, 8, 9 add or fix related test cases.

- [patch 2] remove now unnecessary byte adjustment

Lower the expected level of traffic in the pp_alloc_fail test
and calculate failure counter thresholds based on the traffic
rather than using a fixed constant.
We only have "QEMU HW" in NIPA right now, and the test (due to
debug dependencies) only works on debug kernels in the first place.
We need some place for it to pass otherwise it seems to be bit
rotting. So lower the traffic threshold so that it passes on QEMU
and with a debug kernel...

Rx processing under normal circumstances has 3 rings - 2 buffer
rings (heads, payloads) and a completion ring. All the rings
have a struct fbnic_ring. Make sure we expose alloc_failed
counter from the buffer rings, previously only the alloc_failed
from the completion ring was reported, even tho all ring types
may increment this counter (buffer rings in __fbnic_fill_bdq()).
This makes the pp_alloc_fail.py test pass, it expects the qstat
to be incrementing as page pool injections happen.

When rings are freed - stats get added to the device level stat
structs. Save the stats from the XDP_TX ring just as Tx stats.
Previously they would be saved to Rx and Tx stats. So we'd not
see XDP_TX packets as Rx during runtime but after an down/up cycle
the packets would appear in stats.
Correct the helper used by ethtool code which does a runtime
config switch.

Make XDP-handled packets appear in the Rx stats. The driver has been
counting XDP_TX packets on the Tx ring, but there wasn't much accounting
on the Rx side (the Rx bytes appear to be incremented on XDP_TX but
XDP_DROP / XDP_ABORT are only counted as Rx drops).
Counting XDP_TX packets (not just bytes) in Rx stats looks like
a simple bug of omission.
The XDP_DROP handling appears to be intentional. Whether XDP_DROP
packets should be counted in interface-level Rx stats is a bit
unclear historically. When we were defining qstats, however,
we clarified based on operational experience that in this context:
name: rx-packets
doc: |
Number of wire packets successfully received and passed to the stack.
For drivers supporting XDP, XDP is considered the first layer
of the stack, so packets consumed by XDP are still counted here.
fbnic does not obey this requirement. Since XDP support has been added
in current release cycle, instead of splitting interface and qstat
handling - make them both follow the qstat definition.
Another small tweak here is that we count bytes as received on the wire
rather than post-XDP bytes (xdp_get_buff_len() vs skb->len).

XDP_TX typically uses no offloads. To optimize XDP we added a "default
descriptor" feature to the chip, which allows us to send XDP frames with
just the buffer descriptors (DMA address + length). All the metadata
descriptors are derived from the queue config.
Commit under Fixes missed adding setting the defaults up when transplanting
the code from the prototype driver. Importantly after reset the "request
completion" bit is not set. Packets still get sent but there's no
completion, so ring is not cleaned up. We can send one ring's worth
of packets and then will start dropping all frames that got the XDP_TX
action from the XDP prog.

Florian Westphal says:
====================
netfilter: updates for net
The following patchset contains Netfilter fixes for *net*:
1) Fix crash (call recursion) when nftables synproxy extension is used
in an object map. When this feature was added in v5.4 the required
hook call validation was forgotten.
Fix from Fernando Fernandez Mancera.
2) bridge br_vlan_fill_forward_path_pvid uses incorrect
rcu_dereference_protected(); we only have rcu read lock but not
RTNL. Fix from Eric Woudstra.
Last two patches address flakes in two existing selftests.

- Extended 'perf annotate' with DWARF type information (--code-with-type)
integration in the TUI, including a 'T' hotkey to toggle it.
- Enhanced 'perf bench mem' with new mmap() workloads and control over
page/chunk sizes.
- Fix 'perf stat' error handling to correctly display unsupported events.
- Improved support for Clang cross-compilation.
- Refactored LLVM and Capstone disasm for modularity.
- Introduced the :X modifier to exclude an event from automatic regrouping.
- Adjusted KVM sampling defaults to use the "cycles" event to prevent failures.
- Added comprehensive support for decoding PowerPC Dispatch Trace Log (DTL).
- Updated Arm SPE tracing logic for better analysis of memory and snoop
details.
- Synchronized Intel PMU events and metrics with TMA 5.1 across multiple
processor generations.
- Converted dependencies like libperl and libtracefs to be opt-in.
- Handle more Rust symbols in kallsyms ('N', debugging).
- Improve the python binding to allow for python based tools to use more
of the libraries, add a 'ilist' utility to test those new bindings.
- Various 'perf test' fixes.
- Kan Liang no longer a perf tools reviewer.
