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.

dlm: return -ENOENT if no comm was found
dlm: fix srcu_read_lock() return type to int
dlm: fix removal of rsb struct that is master and dir record
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:
- 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.
Release notes from the previous 6.13 pull request:
- 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.

Pull btrfs updates from David Sterba:
"User visible changes, features:
- rebuilding of the free space tree at mount time is done in more
transactions, fix potential hangs when the transaction thread is
blocked due to large amount of block groups
- more read IO balancing strategies (experimental config), add two
new ways how to select a device for read if the profiles allow that
(all RAID1*), the current default selects the device by pid which
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
Core:
- 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
- improved or fixed error handling in a few cases (compression,
delalloc)
- raid stripe tree:
- fix various cases with extent range splitting or deleting
- implement hole punching to extent range
- reduce number of stripe tree lookups during bio submission
- more self-tests
- updated self-tests (delayed refs)
- error handling improvements
- cleanups, refactoring
- remove rest of backref caching infrastructure from relocation,
not needed anymore
- error message updates
- remove unnecessary calls when extent buffer was marked dirty
- unused parameter removal
- code moved to new files

Let's factorise it out to inet6_rtm_newaddr() so that we can validate

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.

Async flips often require bigger alignment that sync flips.
Currently we have HAS_ASYNC_FLIPS() checks strewn about to
inidcate that async flips are generally supported and thus
we want more alignment. Switch that over to using
intel_plane_can_async_flip() so that we can handle these
in a slightly less messy way. Currently we don't have cases
where async flips would require different alignment for
different modifiers on the same plane.
We'll also move the HAS_ASYNC_FLIPS() check to the plane init
code so that we can still use that as a quick way to disable
the async flips workarounds for testing purposes.

Looks like CCS + async flips has been a thing for a while now.
Enable this for TGL+ render compression modifiers.
Note that we can't update AUX_DIST during async flips we must
check to make sure it remains unchanged.
We also can't do clear color. Supposedly there was some attempt
to make it work, but apparently the issues only got ironed out
in MTL. For now we'll not worry about it and refuse async flips
with clear color modifiers.
Bspec claims that media compression doesn't support async flips.
Based on a quick test it does seem to work to some degree, but
perhaps it has issues as well. Let's trust the spec here and
continue to refuse async flips + media compression.

net: ethtool: fixes for HDS threshold
Quick follow up on the HDS threshold work, since the merge window

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

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.

Merge cpufreq updates for 6.14:
- Use str_enable_disable()-like helpers in cpufreq (Krzysztof
Kozlowski).
- Extend the Apple cpufreq driver to support more SoCs (Hector Martin,
Nick Chan).
- Add new cpufreq driver for Airoha SoCs (Christian Marangi).
- Fix using cpufreq-dt as module (Andreas Kemnade).
- Minor fixes for Sparc, SCMI, and Qcom cpufreq drivers (Ethan Carter
Edwards, Sibi Sankar, Manivannan Sadhasivam).
- Fix the maximum supported frequency computation in the ACPI cpufreq
driver to avoid relying on unfounded assumptions (Gautham Shenoy).
- Fix an amd-pstate driver regression with preferred core rankings not
being used (Mario Limonciello).
- Fix a precision issue with frequency calculation in the amd-pstate
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).
