b5cbe7c00a Merge tag 'v6.6-rc3.vfs.ctime.revert' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull finegrained timestamp reverts from Christian Brauner:
 "Earlier this week we sent a few minor fixes for the multi-grained
  timestamp work in [1]. While we were polishing those up after Linus
  realized that there might be a nicer way to fix them we received a
  regression report in [2] that fine grained timestamps break gnulib
  tests and thus possibly other tools.

  The kernel will elide fine-grain timestamp updates when no one is
  actively querying for them to avoid performance impacts. So a sequence
  like write(f1) stat(f2) write(f2) stat(f2) write(f1) stat(f1) may
  result in timestamp f1 to be older than the final f2 timestamp even
  though f1 was last written too but the second write didn't update the
  timestamp.

  Such plotholes can lead to subtle bugs when programs compare
  timestamps. For example, the nap() function in [2] will estimate that
  it needs to wait one ns on a fine-grain timestamp enabled filesytem
  between subsequent calls to observe a timestamp change. But in general
  we don't update timestamps with more than one jiffie if we think that
  no one is actively querying for fine-grain timestamps to avoid
  performance impacts.

  While discussing various fixes the decision was to go back to the
  drawing board and ultimately to explore a solution that involves only
  exposing such fine-grained timestamps to nfs internally and never to
  userspace.

  As there are multiple solutions discussed the honest thing to do here
  is not to fix this up or disable it but to cleanly revert. The general
  infrastructure will probably come back but there is no reason to keep
  this code in mainline.

  The general changes to timestamp handling are valid and a good cleanup
  that will stay. The revert is fully bisectable"

Florian Westphal says:

====================
netfilter updates for net

The following three patches fix regressions in the netfilter subsystem:

1. Reject attempts to repeatedly toggle the 'dormant' flag in a single
   transaction.  Doing so makes nf_tables lose track of the real state
   vs. the desired state.  This ends with an attempt to unregister hooks
   that were never registered in the first place, which yields a splat.

2. Fix element counting in the new nftables garbage collection infra
   that came with 6.5:  More than 255 expired elements wraps a counter
   which results in memory leak.

3. Since 6.4 ipset can BUG when a set is renamed while a CREATE command
   is in progress, fix from Jozsef Kadlecsik.

fc21f08375 sfc: handle error pointers returned by rhashtable_lookup_get_insert_fast()
Several places in TC offload code assumed that the return from
 rhashtable_lookup_get_insert_fast() was always either NULL or a valid
 pointer to an existing entry, but in fact that function can return an
 error pointer.  In that case, perform the usual cleanup of the newly
 created entry, then pass up the error, rather than attempting to take a
 reference on the old entry.

1703b2e0de igc: Expose tx-usecs coalesce setting to user
When users attempt to obtain the coalesce setting using the
ethtool command, current code always returns 0 for tx-usecs.
This is because I225/6 always uses a queue pair setting, hence
tx_coalesce_usecs does not return a value during the
igc_ethtool_get_coalesce() callback process. The pair queue
condition checking in igc_ethtool_get_coalesce() is removed by
this patch so that the user gets information of the value of tx-usecs.

Even if i225/6 is using queue pair setting, there is no harm in
notifying the user of the tx-usecs. The implementation of the current
code may have previously been a copy of the legacy code i210.
Since I225 has the queue pair setting enabled, tx-usecs will always adhere
to the user-set rx-usecs value. An error message will appear when the user
attempts to set the tx-usecs value for the input parameters because,
by default, they should only set the rx-usecs value.

This patch also adds the helper function to get the
previous rx coalesce value similar to tx coalesce.

How to test:
User can get the coalesce value using ethtool command.

Example command:
Get: ethtool -c <interface>

Previous output:

rx-usecs: 3
rx-frames: n/a
rx-usecs-irq: n/a
rx-frames-irq: n/a

tx-usecs: 0
tx-frames: n/a
tx-usecs-irq: n/a
tx-frames-irq: n/a

New output:

rx-usecs: 3
rx-frames: n/a
rx-usecs-irq: n/a
rx-frames-irq: n/a

tx-usecs: 3
tx-frames: n/a
tx-usecs-irq: n/a
tx-frames-irq: n/a

ASoC: Fixes for v6.6

Quite a large collection of fixes, with numbers boosted by multiple
vendors sending multi-patch serieses.  Nothing super major, and also one
device quirk.

4a0f07d71b net/handshake: Fix memory leak in __sock_create() and sock_alloc_file()
When making CONFIG_DEBUG_KMEMLEAK=y and CONFIG_DEBUG_KMEMLEAK_AUTO_SCAN=y,
modprobe handshake-test and then rmmmod handshake-test, the below memory
leak is detected.

The struct socket_alloc which is allocated by alloc_inode_sb() in
__sock_create() is not freed. And the struct dentry which is allocated
by __d_alloc() in sock_alloc_file() is not freed.

Since fput() will call file->f_op->release() which is sock_close() here and
it will call __sock_release(). and fput() will call dput(dentry) to free
the struct dentry. So replace sock_release() with fput() to fix the
below memory leak. After applying this patch, the following memory leak is
never detected.

7433b6d2af netfilter: ipset: Fix race between IPSET_CMD_CREATE and IPSET_CMD_SWAP
Kyle Zeng reported that there is a race between IPSET_CMD_ADD and IPSET_CMD_SWAP
in netfilter/ip_set, which can lead to the invocation of `__ip_set_put` on a
wrong `set`, triggering the `BUG_ON(set->ref == 0);` check in it.

The race is caused by using the wrong reference counter, i.e. the ref counter instead
of ref_netlink.

cf5000a778 netfilter: nf_tables: fix memleak when more than 255 elements expired
When more than 255 elements expired we're supposed to switch to a new gc
container structure.

This never happens: u8 type will wrap before reaching the boundary
and nft_trans_gc_space() always returns true.

This means we recycle the initial gc container structure and
lose track of the elements that came before.

While at it, don't deref 'gc' after we've passed it to call_rcu.

When enslave a vlan device to team device and team device type is changed
from non-ether to ether, header_ops of team device is changed to
vlan_header_ops. That is incorrect and will trigger null-ptr-deref
for vlan->real_dev in vlan_dev_hard_header() because team device is not
a vlan device.

Cache eth_header_ops in team_setup(), then assign cached header_ops to
header_ops of team net device when its type is changed from non-ether
to ether to fix the bug.

0770063096 net: hns3: add 5ms delay before clear firmware reset irq source
Currently the reset process in hns3 and firmware watchdog init process is
asynchronous. we think firmware watchdog initialization is completed
before hns3 clear the firmware interrupt source. However, firmware
initialization may not complete early.

so we add delay before hns3 clear firmware interrupt source and 5 ms delay
is enough to avoid second firmware reset interrupt.

looks like:

The reason is the rxq|txq_stats structures are not what expected
because stmmac_open() -> __stmmac_open() the structure is overwritten
by "memcpy(&priv->dma_conf, dma_conf, sizeof(*dma_conf));"
This causes the well initialized syncp member of rxq|txq_stats is
overwritten unexpectedly as pointed out by Johannes and Uwe.

Fix this issue by moving rxq|txq_stats back to stmmac_extra_stats. For
SMP cache friendly, we also mark stmmac_txq_stats and stmmac_rxq_stats
as ____cacheline_aligned_in_smp.

0fc6ff5a0f xen/efi: refactor deprecated strncpy
`strncpy` is deprecated for use on NUL-terminated destination strings [1].

`efi_loader_signature` has space for 4 bytes. We are copying "Xen" (3 bytes)
plus a NUL-byte which makes 4 total bytes. With that being said, there is
currently not a bug with the current `strncpy()` implementation in terms of
buffer overreads but we should favor a more robust string interface
either way.

A suitable replacement is `strscpy` [2] due to the fact that it guarantees
NUL-termination on the destination buffer while being functionally the
same in this case.

49147beb0c x86/xen: allow nesting of same lazy mode
When running as a paravirtualized guest under Xen, Linux is using
"lazy mode" for issuing hypercalls which don't need to take immediate
effect in order to improve performance (examples are e.g. multiple
PTE changes).

There are two different lazy modes defined: MMU and CPU lazy mode.
Today it is not possible to nest multiple lazy mode sections, even if
they are of the same kind. A recent change in memory management added
nesting of MMU lazy mode sections, resulting in a regression when
running as Xen PV guest.

Technically there is no reason why nesting of multiple sections of the
same kind of lazy mode shouldn't be allowed. So add support for that
for fixing the regression.

a4a7644c15 x86/xen: move paravirt lazy code
Only Xen is using the paravirt lazy mode code, so it can be moved to
Xen specific sources.

This allows to make some of the functions static or to merge them into
their only call sites.

While at it do a rename from "paravirt" to "xen" for all moved
specifiers.

No functional change.
