We are missing netif_napi_del() and am65_cpsw_nuss_free_tx/rx_chns()
in error path when am65_cpsw_nuss_init_tx/rx_chns() is used anywhere
other than at probe(). i.e. am65_cpsw_nuss_update_tx_rx_chns and
am65_cpsw_nuss_resume()
As reported, in am65_cpsw_nuss_update_tx_rx_chns(),
if am65_cpsw_nuss_init_tx_chns() partially fails then
devm_add_action(dev, am65_cpsw_nuss_free_tx_chns,..) is added
but the cleanup via am65_cpsw_nuss_free_tx_chns() will not run.
Same issue exists for am65_cpsw_nuss_init_tx/rx_chns() failures
in am65_cpsw_nuss_resume() as well.
This would otherwise require more instances of devm_add/remove_action
and is clearly more of a distraction than any benefit.
So, drop devm_add/remove_action for am65_cpsw_nuss_free_tx/rx_chns()
and call am65_cpsw_nuss_free_tx/rx_chns() and netif_napi_del()
where required.

Pull bcachefs updates from Kent Overstreet:
"Lots of scalability work, another big on-disk format change. On-disk
format version goes from 1.13 to 1.20.
Like 6.11, this is another big and expensive automatic/required on
disk format upgrade. This is planned to be the last big on disk format
upgrade before the experimental label comes off. There will be one
more minor on disk format update for a few things that couldn't make
this release.
Headline improvements:
- Self healing work:
Allocator and reflink now run the exact same check/repair code that
fsck does at runtime, where applicable.
The long term goal here is to remove inconsistent() errors (that
cause us to go emergency read only) by lifting fsck code up to
normal runtime paths; we should only go emergency read-only if we
detect an inconsistency that was due to a runtime bug - or truly
catastrophic damage (corrupted btree roots/interior nodes).
- Reflink repair no longer deletes reflink pointers:
Instead we flip an error bit and log the error, and they can still
be deleted by file deletion. This means a temporary failure to find
an indirect extent (perhaps repaired later by btree node scan)
won't result in unnecessary data loss
- Improvements to rebalance data path option handling:
We can now correctly apply changed filesystem-level io path options
to pending rebalance work, and soon we'll be able to apply
file-level io path option changes to indirect extents
- Fix mount time regression that some users encountered post the 6.11
disk accounting rewrite.
Accounting keys were encoded little endian (typetag in the low
bits) - which didn't anticipate adding accounting keys for every
inode, which aren't stored in memory and we don't want to scan at
mount time.
- fsck time on large filesystems is improved by multiple orders of
magnitude. Previously, 100TB was about the practical max filesystem
size, where users were reporting fsck times of a day+. With the new
changes (which nearly eliminate backpointers fsck overhead), we
fsck'd a filesystem with 10PB of data in 1.5 hours.
The problematic fsck passes were walking every extent and checking
for missing backpointers, and walking every backpointer to check
for dangling backpointers. As we've been adding more and more
runtime self healing there was no reason to keep around the
backpointers -> extents pass; dangling backpointers are just
deleted, and we can do that when using them - thus, backpointers ->
extents is now only run in debug mode.
extents -> backpointers does need to exist, since missing
backpointers would mean we can't find data to move it (for e.g.
copygc, device evacuate, scrub). But the new on disk format version
makes possible a new strategy where we sum up backpointers within a
bucket and check it against the bucket sector counts, and then only
scan for missing backpointers if the counts are off (and then, only
for specific buckets).
Full list of on disk format changes:
- 1.14: backpointer_bucket_gen
Backpointers now have a field for the bucket generation number,
replacing the obsolete bucket_offset field. This is needed for the
new "sum up backpointers within a bucket" code, since backpointers
use the btree write buffer - meaning we will see stale reads, and
this runs online, with the filesystem in full rw mode.
- 1.15: disk_accounting_big_endian
As previously described, fix the endianness of accounting keys so
that accounting keys with the same typetag sort together, and
accounting read can skip types it's not interested in.
- 1.16: reflink_p_may_update_opts:
This version indicates that a new reflink pointer field is
understood and may be used; the field indicates whether the reflink
pointer has permissions to update IO path options (e.g.
compression, replicas) may be updated on the indirect extent it
points to.
This completes the rebalance/reflink data path option handling from
the 6.13 pull request.
- 1.17: inode_depth
Add a new inode field, bi_depth, to accelerate the
check_directory_structure fsck path, which checks for loops in the
filesystem heirarchy.
check_inodes and check_dirents check connectivity, so
check_directory_structure only has to check for loops - by walking
back up to the root from every directory.
But a path can't be a loop if it has a counter that increases
monotonically from root to leaf - adding a depth counter means that
we can check for loops with only local (parent -> child) checks. We
might need to occasionally renumber the depth field in fsck if
directories have been moved around, but then future fsck runs will
be much faster.
- 1.18: persistent_inode_cursors
Previously, the cursor used for inode allocation was only kept in
memory, which meant that users with large filesystems and lots of
files were reporting that the first create after mounting would
take awhile - since it had to scan from the start.
Inode allocation cursors are now persistent, and also include a
generation field (incremented on wraparound, which will only happen
if inode allocation is restricted to 32 bit inodes), so that we
don't have to leave inode_generation keys around after a delete.
The option for 32 bit inode numbers may now also be set on
individual directories, and non-32 bit inode allocations are
disallowed from allocating from the 32 bit part of the inode number
space.
- 1.19: autofix_errors
Runtime self healing is now the default.o
- 1.20: directory size (from Hongbo)
directory i_size is now meaningful, and not 0"

"User visible changes, features:

- more read IO balancing strategies (experimental config), add two
new ways how to select a device for read if the profiles allow that

is good on average but less performant for single reader workloads
- select preferred device for all reads (namely for testing)
- round-robin, balance reads across devices relevant for the
requested IO range
- add encoded write ioctl support to io_uring (read was added in
6.12), basis for writing send stream using that instead of
syscalls, non-blocking mode is not yet implemented
- support FS_IOC_READ_VERITY_METADATA, applications can use the
metadata to do their own verification
- pass inode's i_write_hint to bios, for parity with other
filesystems, ioctls F_GET_RW_HINT/F_SET_RW_HINT

- in zoned mode: allow to directly reclaim a block group by simply
resetting it, then it can be reused and another block group does
not need to be allocated
- super block validation now also does more comprehensive sys array
validation, adding it to the points where superblock is validated
(post-read, pre-write)
- subpage mode fixes:
- fix double accounting of blocks due to some races

Netfilter updates for net-next
The following batch contains Netfilter updates for net-next:
1) Unbreak set size settings for rbtree set backend, intervals in
rbtree are represented as two elements, this detailed is leaked
to userspace leading to bogus ENOSPC from control plane.
2) Remove dead code in br_netfilter's br_nf_pre_routing_finish()
due to never matching error when looking up for route,
from Antoine Tenart.
3) Simplify check for device already in use in flowtable,
from Phil Sutter.
4) Three patches to restore interface name field in struct nft_hook
and use it, this is to prepare for wildcard interface support.
From Phil Sutter.
5) Do not remove netdev basechain when last device is gone, this is
for consistency with the flowtable behaviour. This allows for netdev
basechains without devices. Another patch to simplify netdev event
notifier after this update. Also from Phil.
6) Two patches to add missing spinlock when flowtable updates TCP
state flags, from Florian Westphal.
7) Simplify __nf_ct_refresh_acct() by removing skbuff parameter,
also from Florian.
8) Flowtable gc now extends ct timeout for offloaded flow. This
is to address a possible race that leads to handing over flow
to classic path with long ct timeouts.
9) Tear down flow if cached rt_mtu is stale, before this patch,
packet is handed over to classic path but flow entry still remained
in place.
10) Revisit the flowtable teardown strategy, which was originally
designed to release flowtable hardware entries early. Add a new
CLOSING flag that still allows hardware to release entries when
fin/rst is seen, but keeps the flow entry in place when the
TCP connection is closed. Release flow after timeout or when a new
syn packet is seen for TCP reopen scenario.

net: ethtool: fixes for HDS threshold
Quick follow up on the HDS threshold work, since the merge window
is upon us.
Fix the bnxt implementation to apply the settings right away,
because we update the parameters _after_ configuring HW user
needed to reconfig the device twice to get the settings to stick.
For this I took the liberty of moving the config to a separate
struct. This follows my original thinking for the queue API.
It should also fit more neatly into how many drivers which
support safe config update operate. Drivers can allocate
new objects using the "pending" struct.

300-400B RPC requests are fairly common. With the current default
of 256B HDS threshold bnxt ends up splitting those, lowering PCIe
bandwidth efficiency and increasing the number of memory allocation.
Increase the HDS threshold to fit 4 buffers in a 4k page.
This works out to 640B as the threshold on a typical kernel confing.
This change increases the performance for a microbenchmark which
receives 400B RPCs and sends empty responses by 4.5%.
Admittedly this is just a single benchmark, but 256B works out to
just 6 (so 2 more) packets per head page, because shinfo size
dominates the headers.
Now that we use page pool for the header pages I was also tempted
to default rx_copybreak to 0, but in synthetic testing the copybreak
size doesn't seem to make much difference.

driver (Naresh Solanki).
- Add ftrace event to the amd-pstate driver for active mode (Mario
Limonciello).
- Set default EPP policy on Ryzen processors in amd-pstate (Mario
Limonciello).
- Clean up the amd-pstate cpufreq driver and optimize it to increase
code reuse (Mario Limonciello, Dhananjay Ugwekar).
- Use CPPC to get scaling factors between HWP performance levels and
frequency in the intel_pstate driver and make it stop using a built
-in scaling factor for the Arrow Lake processor (Rafael Wysocki).
- Make intel_pstate initialize epp_policy to CPUFREQ_POLICY_UNKNOWN for
consistency with CPU offline (Christian Loehle).
- Fix superfluous updates caused by need_freq_update in the schedutil
cpufreq governor (Sultan Alsawaf).

This is a follow-up of commit d460b04bc4 ("af_unix: Clean up
error paths in unix_stream_sendmsg().").
If we initialise skb with NULL in unix_stream_sendmsg(), we can
reuse the existing out_pipe label for the SEND_SHUTDOWN check.
Let's rename it and adjust the existing label as out_pipe_lock.
While at it, size and data_len are moved to the while loop scope.

unix_dgram_disconnected() is called from two places:
1. when a connect()ed socket dis-connect()s or re-connect()s to
another socket
2. when sendmsg() fails because the peer socket that the client
has connect()ed to has been close()d
Then, the client's recv queue is purged to remove all messages from
the old peer socket.
Let's define a new drop reason for that case.
# echo 1 > /sys/kernel/tracing/events/skb/kfree_skb/enable
# python3
>>> from socket import *
>>>
>>> # s1 has a message from s2
>>> s1, s2 = socketpair(AF_UNIX, SOCK_DGRAM)
>>> s2.send(b'hello world')
>>>
>>> # re-connect() drops the message from s2
>>> s3 = socket(AF_UNIX, SOCK_DGRAM)
>>> s3.bind('')
>>> s1.connect(s3.getsockname())
# cat /sys/kernel/tracing/trace_pipe

unix_stream_read_skb() is called when BPF SOCKMAP reads some data
from a socket in the map.
SOCKMAP does not support MSG_OOB, and reading OOB results in a drop.
Let's set drop reasons respectively.
* SOCKET_CLOSE : the socket in SOCKMAP was close()d
* UNIX_SKIP_OOB : OOB was read from the socket in SOCKMAP

AF_UNIX SOCK_STREAM socket supports MSG_OOB.
When OOB data is sent to a socket, recv() will break at that point.
If the next recv() does not have MSG_OOB, the normal data following
the OOB data is returned.
Then, the OOB skb is dropped.
Let's define a new drop reason for that case in manage_oob().
# echo 1 > /sys/kernel/tracing/events/skb/kfree_skb/enable
# python3
>>> from socket import *
>>> s1, s2 = socketpair(AF_UNIX)
>>> s1.send(b'a', MSG_OOB)
>>> s1.send(b'b')
>>> s2.recv(2)
b'b'
