When sockfd_lookup() fails, gtp_encap_enable_socket() returns a
NULL pointer, but its callers only check for error pointers thus miss
the NULL pointer case.
Fix it by returning an error pointer with the error code carried from
sockfd_lookup().
(I found this bug during code inspection.)

Fixes for IPsec over bonding
This patchset provides bug fixes for IPsec over bonding driver.
It adds the missing xdo_dev_state_free API, and fixes "scheduling while
atomic" by using mutex lock instead.

Add this implementation for bonding, so hardware resources can be
freed from the active slave after xfrm state is deleted. The netdev
used to invoke xdo_dev_state_free callback, is saved in the xfrm state
(xs->xso.real_dev), which is also the bond's active slave. To prevent
it from being freed, acquire netdev reference before leaving RCU
read-side critical section, and release it after callback is done.
And call it when deleting all SAs from old active real interface while
switching current active slave.

fq_dequeue() has a complex logic to find packets in one of the 3 bands.
As Neal found out, it is possible that one band has a deficit smaller
than its weight. fq_dequeue() can return NULL while some packets are
elligible for immediate transmit.
In this case, more than one iteration is needed to refill pband->credit.
With default parameters (weights 589824 196608 65536) bug can trigger
if large BIG TCP packets are sent to the lowest priority band.

With recent work to the doorbell workaround code a small hole was
introduced that could cause a tx_timeout. This happens if the rx
dbell_deadline goes beyond the netdev watchdog timeout set by the driver
(i.e. 2 seconds). Fix this by changing the netdev watchdog timeout to 5
seconds and reduce the max rx dbell_deadline to 4 seconds.
The test that can reproduce the issue being fixed is a multi-queue send
test via pktgen with the "burst" setting to 1. This causes the queue's
doorbell to be rung on every packet sent to the driver, which may result
in the device missing doorbells due to the high doorbell rate.

The device is not present, note lack of __LINK_STATE_PRESENT (0b10).
This is the same sort of panic as observed in commit 4224cfd7fb

The mana_hwc_rx_event_handler() / mana_hwc_handle_resp() calls
complete(&ctx->comp_event) before posting the wqe back. It's
possible that other callers, like mana_create_txq(), start the
next round of mana_hwc_send_request() before the posting of wqe.
And if the HW is fast enough to respond, it can hit no_wqe error
on the HW channel, then the response message is lost. The mana
driver may fail to create queues and open, because of waiting for
the HW response and timed out.
Sample dmesg:
[ 528.610840] mana 39d4:00:02.0: HWC: Request timed out!
[ 528.614452] mana 39d4:00:02.0: Failed to send mana message: -110, 0x0
[ 528.618326] mana 39d4:00:02.0 enP14804s2: Failed to create WQ object: -110

This driver only appears to have received sporadic clean-ups, typically
part of some tree-wide activity, and fixes for quite some time. And
according to the maintainer, Guo-Fu Tseng, the device has been EOLed for
a long time (see Link).
Accordingly, it seems appropriate to mark this driver as odd fixes.

This is part of an effort to assign a section in MAINTAINERS to header
files that relate to Networking. In this case the files with "net" or
"skbuff" in their name.
This patch adds a number of such files to the NETWORKING DRIVERS
and NETWORKING [GENERAL] sections.

This aims to add limited globs to improve the coverage of header files
in the NETWORKING DRIVERS and NETWORKING [GENERAL] sections.
It is done so in a minimal way to exclude overlap with other sections.
And so as not to require "X" entries to exclude files otherwise
matched by these new globs.
While imperfect, due to it's limited nature, this does extend coverage
of header files by these sections. And aims to automatically cover
new files that seem very likely belong to these sections.
The include/linux/netdev* glob (both sections)
+ Subsumes the entries for:
- include/linux/netdevice.h
+ Extends the sections to cover
- include/linux/netdevice_xmit.h
- include/linux/netdev_features.h
The include/uapi/linux/netdev* globs: (both sections)
+ Subsumes the entries for:
- include/linux/netdevice.h
+ Extends the sections to cover
- include/linux/netdev.h
The include/linux/skbuff* glob (NETWORKING [GENERAL] section only):
+ Subsumes the entry for:
- include/linux/skbuff.h
+ Extends the section to cover
- include/linux/skbuff_ref.h
A include/uapi/linux/net_* glob was not added to the NETWORKING [GENERAL]
section. Although it would subsume the entry for
include/uapi/linux/net_namespace.h, which is fine, it would also extend
coverage to:
- include/uapi/linux/net_dropmon.h, which belongs to the
NETWORK DROP MONITOR section
- include/uapi/linux/net_tstamp.h which, as per an earlier patch in this
series, belongs to the SOCKET TIMESTAMPING section

Some CPT AF registers are per LF and others are global. Translation
of PF/VF local LF slot number to actual LF slot number is required
only for accessing perf LF registers. CPT AF global registers access
do not require any LF slot number. Also, there is no reason CPT

The current implementation incorrectly sets the mode bit of the PHY chip.
Bit 15 (RTL8211F_LEDCR_MODE) should not be shifted together with the
configuration nibble of a LED- it should be set independently of the
index of the LED being configured.
As a consequence, the RTL8211F LED control is actually operating in Mode A.
Fix the error by or-ing final register value to write with a const-value of
RTL8211F_LEDCR_MODE, thus setting Mode bit explicitly.

Pull erofs fixes from Gao Xiang:
"As I mentioned in the merge window pull request, there is a regression
which could cause system hang due to page migration. The corresponding
fix landed upstream through MM tree last week (commit 2e6506e1c4:
"mm/migrate: fix deadlock in migrate_pages_batch() on large folios"),
therefore large folios can be safely allowed for compressed inodes and
stress tests have been running on my fleet for over 20 days without
any regression. Users have explicitly requested this for months, so
let's allow large folios for EROFS full cases now for wider testing.
Additionally, there is a fix which addresses invalid memory accesses
on a failure path triggered by fault injection and two minor cleanups
to simplify the codebase.

- Allow large folios on compressed inodes
