cifs: fix setting SecurityFlags to true
If you try to set /proc/fs/cifs/SecurityFlags to 1 it will set them to CIFSSEC_MUST_NTLMV2 which no longer is relevant (the less secure ones like lanman have been removed from cifs.ko) and is also missing some flags (like for signing and encryption) and can even cause mount to fail, so change this to set it to Kerberos in this case. Also change the description of the SecurityFlags to remove mention of flags which are no longer supported.

A quick follow up to yesterday's PR. We got a regressions report for
the bnxt patch as soon as it got to your tree. The ethtool fix is also
good to have, although it's an older regression.
Current release - regressions:
- eth: bnxt_en: fix crash in bnxt_get_max_rss_ctx_ring() on older HW
when user tries to decrease the ring count
Previous releases - regressions:
- ethtool: fix RSS setting, accept "no change" setting if the driver
doesn't support the new features
- eth: i40e: remove needless retries of NVM update, don't wait 20min
when we know the firmware update won't succeed

Merge tag 'for-6.10-rc7-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux
Pull btrfs fixes from David Sterba:
"Fix a regression in extent map shrinker behaviour.
In the past weeks we got reports from users that there are huge
latency spikes or freezes. This was bisected to newly added shrinker
of extent maps (it was added to fix a build up of the structures in
memory).
I'm assuming that the freezes would happen to many users after release
so I'd like to get it merged now so it's in 6.10. Although the diff
size is not small the changes are relatively straightforward, the
reporters verified the fixes and we did testing on our side.
The fixes:
- adjust behaviour under memory pressure and check lock or scheduling
conditions, bail out if needed
- synchronize tracking of the scanning progress so inode ranges are
not skipped or work duplicated
- do a delayed iput when scanning a root so evicting an inode does
not slow things down in case of lots of dirty data, also fix
lockdep warning, a deadlock could happen when writing the dirty
data would need to start a transaction"

ARM: SoC fixes for 6.10, part 3
Most of these changes are Qualcomm SoC specific and came in just after I sent out the last set of fixes. This includes two regression fixes for SoC drivers, a defconfig change to ensure the Lenovo X13s is usable and 11 changes to DT files to fix regressions and minor platform specific issues. Tony and Chunyan step back from their respective maintainership roles on the omap and unisoc platforms, and Christophe in turn takes over maintaining some of the Freescale SoC drivers that he has been taking care of in practice already. Lastly, there are two trivial fixes for the davinci and sunxi platforms. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEiK/NIGsWEZVxh/FrYKtH/8kJUicFAmaRHVYACgkQYKtH/8kJ UickAA//SiEl5R0xLYuEfv3GViRMamZ0xGiWz90SlY/TJoY8fh4CajmRjwcXrAEF qz/VzfaR7p2J+WXGmtqfBb90QQbEi0EIdGyhMn9vtnoN7GvMilFQTq0X+tzINPB7 gXywgjfIVXuQoUkNvrco7aNA53lYbXoTWzTfyiDFox0DS+sMARd/s/NnjEXNNkeQ FNAUm+5YL/UzfORpo1gtQTjAYxu9CDyaCaxrSYmCM3nMV40yDPrFEFW0NTlBeXXE 5zXbC7N6Rm0vy/N3GWzcTwZcBEp1TLolUJS6obw64KUM0vl3yvUUkRbEH1R8WUVR rUnrx/aw+1BfM7DKxQ/zX8dhVLs3/i3mklnX0omxofylbL/u+B8p36BPA7aZQUUh YttwVpJny0zIRlgveoUi1wvM9NJkmWBE+L874/39SaB3qVhQN/a936v9NKSmXddE ZRRf+Of+njjg2wZmF2vxxkpM26TOhyi8RFpjlb9wCi/ELSqTUtVwq6iyWHCnjxCS UdDrUOoacsSGnLJZayyHGZBpXfa/21r9pBsjNrK0OT+NeR7qUM2KF1CfGqGhIlDA Dt7R9pQu+OeKK6LbQ345HFzMzE0X5hyphk1dLd7UYe7uDb46c8a0OaxkOnollwYg um03QQ7TPx4iraqbmcmrvz0Iw7gP1Jo3czElvxzM11/J0w2OH5U= =JWNz -----END PGP SIGNATURE----- Merge tag 'arm-fixes-6.10-3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM SoC fixes from Arnd Bergmann: "Most of these changes are Qualcomm SoC specific and came in just after I sent out the last set of fixes.

There are many generations of omaps to maintain, and I will be only active as a hobbyist with time permitting. Let's add more maintainers to ensure continued Linux support. TI is interested in maintaining the active SoCs such as am3, am4 and dra7. And the hobbyists are interested in maintaining some of the older devices, mainly based on omap3 and 4 SoCs. Kevin and Roger have agreed to maintain the active TI parts. Both Kevin and Roger have been working on the omap variants for a long time, and have a good understanding of the hardware. Aaro and Andreas have agreed to maintain the community devices. Both Aaro and Andreas have long experience on working with the earlier TI SoCs. While at it, let's also change me to be a reviewer for the omap1, and drop the link to my old omap web page.

net: ethtool: Fix RSS setting
When user submits a rxfh set command without touching XFRM_SYM_XOR,
rxfh.input_xfrm is set to RXH_XFRM_NO_CHANGE, which is equal to 0xff.
Testing if (rxfh.input_xfrm & RXH_XFRM_SYM_XOR &&
!ops->cap_rss_sym_xor_supported)
return -EOPNOTSUPP;
Will always be true on devices that don't set cap_rss_sym_xor_supported,
since rxfh.input_xfrm & RXH_XFRM_SYM_XOR is always true, if input_xfrm
was not set, i.e RXH_XFRM_NO_CHANGE=0xff, which will result in failure
of any command that doesn't require any change of XFRM, e.g RSS context
or hash function changes.
To avoid this breakage, test if rxfh.input_xfrm != RXH_XFRM_NO_CHANGE
before testing other conditions. Note that the problem will only trigger
with XFRM-aware userspace, old ethtool CLI would continue to work.

spi: Fixes for v6.10
This pull request fixes two regressions that have been bubbling along
for a large part of this release. One is a revert of the multi mode
support for the OMAP SPI controller, this introduced regressions on a
number of systems and while there has been progress on fixing those
we've not got something that works for everyone yet so let's just drop
the change for now. The other is a series of fixes from David Lechner
for his recent message optimisation work, this interacted badly with
spi-mux which is altogether too clever with recursive use of the bus and
creates situations that hadn't been considered.
There are also a couple of small driver specific fixes, including one
more patch from David for sleep duration calculations in the AXI driver.

Pull vfs fixes from Christian Brauner:
"cachefiles:
- Export an existing and add a new cachefile helper to be used in
filesystems to fix reference count bugs
- Use the newly added fscache_ty_get_volume() helper to get a
reference count on an fscache_volume to handle volumes that are
about to be removed cleanly
- After withdrawing a fscache_cache via FSCACHE_CACHE_IS_WITHDRAWN
wait for all ongoing cookie lookups to complete and for the object
count to reach zero
- Propagate errors from vfs_getxattr() to avoid an infinite loop in
cachefiles_check_volume_xattr() because it keeps seeing ESTALE
- Don't send new requests when an object is dropped by raising
CACHEFILES_ONDEMAND_OJBSTATE_DROPPING
- Cancel all requests for an object that is about to be dropped
- Wait for the ondemand_boject_worker to finish before dropping a
cachefiles object to prevent use-after-free
- Use cyclic allocation for message ids to better handle id recycling
- Add missing lock protection when iterating through the xarray when
polling
netfs:
- Use standard logging helpers for debug logging
VFS:
- Fix potential use-after-free in file locks during
trace_posix_lock_inode(). The tracepoint could fire while another
task raced it and freed the lock that was requested to be traced
- Only increment the nr_dentry_negative counter for dentries that are
present on the superblock LRU. Currently, DCACHE_LRU_LIST list is
used to detect this case. However, the flag is also raised in
combination with DCACHE_SHRINK_LIST to indicate that dentry->d_lru
is used. So checking only DCACHE_LRU_LIST will lead to wrong
nr_dentry_negative count. Fix the check to not count dentries that
are on a shrink related list
Misc:
- hfsplus: fix an uninitialized value issue in copy_name
- minix: fix minixfs_rename with HIGHMEM. It still uses kunmap() even

mmc: davinci_mmc: Prevent transmitted data size from exceeding sgm's length
No check is done on the size of the data to be transmiited. This causes
a kernel panic when this size exceeds the sg_miter's length.

btrfs: avoid races when tracking progress for extent map shrinking
We store the progress (root and inode numbers) of the extent map shrinker in fs_info without any synchronization but we can have multiple tasks calling into the shrinker during memory allocations when there's enough memory pressure for example. This can result in a task A reading fs_info->extent_map_shrinker_last_ino after another task B updates it, and task A reading fs_info->extent_map_shrinker_last_root before task B updates it, making task A see an odd state that isn't necessarily harmful but may make it skip certain inode ranges or do more work than necessary by going over the same inodes again. These unprotected accesses would also trigger warnings from tools like KCSAN. So add a lock to protect access to these progress fields.

btrfs: stop extent map shrinker if reschedule is needed
The extent map shrinker can be called in a variety of contexts where we are under memory pressure, and of them is when a task is trying to allocate memory. For this reason the shrinker is typically called with a value of struct shrink_control::nr_to_scan that is much smaller than what we return in the nr_cached_objects callback of struct super_operations (fs/btrfs/super.c:btrfs_nr_cached_objects()), so that the shrinker does not take a long time and cause high latencies. However we can still take a lot of time in the shrinker even for a limited amount of nr_to_scan: 1) When traversing the red black tree that tracks open inodes in a root, as for example with millions of open inodes we get a deep tree which takes time searching for an inode; 2) Iterating over the extent map tree, which is a red black tree, of an inode when doing the rb_next() calls and when removing an extent map from the tree, since often that requires rebalancing the red black tree; 3) When trying to write lock an inode's extent map tree we may wait for a significant amount of time, because there's either another task about to do IO and searching for an extent map in the tree or inserting an extent map in the tree, and we can have thousands or even millions of extent maps for an inode. Furthermore, there can be concurrent calls to the shrinker so the lock might be busy simply because there is already another task shrinking extent maps for the same inode; 4) We often reschedule if we need to, which further increases latency. So improve on this by stopping the extent map shrinking code whenever we need to reschedule and make it skip an inode if we can't immediately lock its extent map tree.

btrfs: use delayed iput during extent map shrinking
When putting an inode during extent map shrinking we're doing a standard
iput() but that may take a long time in case the inode is dirty and we are
doing the final iput that triggers eviction - the VFS will have to wait
for writeback before calling the btrfs evict callback (see
fs/inode.c:evict()).
This slows down the task running the shrinker which may have been
triggered while updating some tree for example, meaning locks are held
as well as an open transaction handle.
Also if the iput() ends up triggering eviction and the inode has no links
anymore, then we trigger item truncation which requires flushing delayed
items, space reservation to start a transaction and that may trigger the
space reclaim task and wait for it, resulting in deadlocks in case the
reclaim task needs for example to commit a transaction and the shrinker
is being triggered from a path holding a transaction handle.
Syzbot reported such a case with the following stack traces:

Since this is a static function there is no need to fully document the function, so replace the kernel-doc comment prefix with a standard comment prefix to remove these warnings.

net, sunrpc: Remap EPERM in case of connection failure in xs_tcp_setup_socket
When using a BPF program on kernel_connect(), the call can return -EPERM. This causes xs_tcp_setup_socket() to loop forever, filling up the syslog and causing the kernel to potentially freeze up. Neil suggested: This will propagate -EPERM up into other layers which might not be ready to handle it. It might be safer to map EPERM to an error we would be more likely to expect from the network system - such as ECONNREFUSED or ENETDOWN. ECONNREFUSED as error seems reasonable. For programs setting a different error can be out of reach (see handling in |

The ct may be dropped if a clash has been resolved but is still passed to
the tcf_ct_flow_table_process_conn function for further usage. This issue
can be fixed by retrieving ct from skb again after confirming conntrack.

net: ks8851: Fix potential TX stall after interface reopen
The amount of TX space in the hardware buffer is tracked in the tx_space
variable. The initial value is currently only set during driver probing.
After closing the interface and reopening it the tx_space variable has
the last value it had before close. If it is smaller than the size of
the first send packet after reopeing the interface the queue will be
stopped. The queue is woken up after receiving a TX interrupt but this
will never happen since we did not send anything.
This commit moves the initialization of the tx_space variable to the
ks8851_net_open function right before starting the TX queue. Also query
the value from the hardware instead of using a hard coded value.
Only the SPI chip variant is affected by this issue because only this
driver variant actually depends on the tx_space variable in the xmit
function.

udp: Set SOCK_RCU_FREE earlier in udp_lib_get_port().
syzkaller triggered the warning [0] in udp_v4_early_demux().
In udp_v[46]_early_demux() and sk_lookup(), we do not touch the refcount
of the looked-up sk and use sock_pfree() as skb->destructor, so we check
SOCK_RCU_FREE to ensure that the sk is safe to access during the RCU grace
period.
Currently, SOCK_RCU_FREE is flagged for a bound socket after being put
into the hash table. Moreover, the SOCK_RCU_FREE check is done too early
in udp_v[46]_early_demux() and sk_lookup(), so there could be a small race
window:

netfilter: nf_tables: prefer nft_chain_validate
nft_chain_validate already performs loop detection because a cycle will
result in a call stack overflow (ctx->level >= NFT_JUMP_STACK_SIZE).
It also follows maps via ->validate callback in nft_lookup, so there
appears no reason to iterate the maps again.
nf_tables_check_loops() and all its helper functions can be removed.
This improves ruleset load time significantly, from 23s down to 12s.
This also fixes a crash bug. Old loop detection code can result in
unbounded recursion:
BUG: TASK stack guard page was hit at ....
Oops: stack guard page: 0000 [#1] PREEMPT SMP KASAN
CPU: 4 PID: 1539 Comm: nft Not tainted 6.10.0-rc5+ #1
[..]
with a suitable ruleset during validation of register stores.
I can't see any actual reason to attempt to check for this from
nft_validate_register_store(), at this point the transaction is still in
progress, so we don't have a full picture of the rule graph.
For nf-next it might make sense to either remove it or make this depend
on table->validate_state in case we could catch an error earlier
(for improved error reporting to userspace).
