Including the transhdrlen in length is a problem when the packet is
partially filled (e.g. something like send(MSG_MORE) happened previously)
when appending to an IPv4 or IPv6 packet as we don't want to repeat the
transport header or account for it twice. This can happen under some
circumstances, such as splicing into an L2TP socket.
The symptom observed is a warning in __ip6_append_data():
WARNING: CPU: 1 PID: 5042 at net/ipv6/ip6_output.c:1800 __ip6_append_data.isra.0+0x1be8/0x47f0 net/ipv6/ip6_output.c:1800
that occurs when MSG_SPLICE_PAGES is used to append more data to an already
partially occupied skbuff. The warning occurs when 'copy' is larger than
the amount of data in the message iterator. This is because the requested
length includes the transport header length when it shouldn't. This can be
triggered by, for example:
sfd = socket(AF_INET6, SOCK_DGRAM, IPPROTO_L2TP);
bind(sfd, ...); // ::1
connect(sfd, ...); // ::1 port 7
send(sfd, buffer, 4100, MSG_MORE);
sendfile(sfd, dfd, NULL, 1024);
Fix this by only adding transhdrlen into the length if the write queue is
empty in l2tp_ip6_sendmsg(), analogously to how UDP does things.
l2tp_ip_sendmsg() looks like it won't suffer from this problem as it builds
the UDP packet itself.

While looking at a related syzbot report involving neigh_periodic_work(),
I found that I forgot to add an annotation when deleting an
RCU protected item from a list.
Readers use rcu_deference(*np), we need to use either
rcu_assign_pointer() or WRITE_ONCE() on writer side
to prevent store tearing.
I use rcu_assign_pointer() to have lockdep support,
this was the choice made in neigh_flush_dev().

When the PF and VF drivers both support flexible rx descriptors and have
negotiated the VIRTCHNL_VF_OFFLOAD_RX_FLEX_DESC capability, the VF driver
queries the PF for the list of supported descriptor formats
(VIRTCHNL_OP_GET_SUPPORTED_RXDIDS). The PF driver is supposed to set the
supported_rxdids bits that correspond to the descriptor formats the
firmware implements. The legacy 32-byte rx desc format is always
supported, even though it is not expressed in GLFLXP_RXDID_FLAGS.
The ice driver does not advertise the legacy 32-byte rx desc support,
which leads to this failure to bring up the VF using the Intel
out-of-tree iavf driver:
iavf 0000:41:01.0: PF does not list support for default Rx descriptor format
...
iavf 0000:41:01.0: PF returned error -5 (VIRTCHNL_STATUS_ERR_PARAM) to our request 6
The in-tree iavf driver does not expose this bug, because it does not
yet implement VIRTCHNL_VF_OFFLOAD_RX_FLEX_DESC.
The ice driver must always set the ICE_RXDID_LEGACY_1 bit in
supported_rxdids. The Intel out-of-tree ice driver and the ice driver in
DPDK both do this.
I copied this piece of the code and the comment text from the Intel
out-of-tree driver.

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.

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.

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

- fix race in readdir when multiple threads can set the last entry
index for a directory
Additionally:
- use exclusive lock when direct io might need to drop privs and call
notify_change()
- don't clear uptodate bit on page after an error, this may lead to a
deadlock in subpage mode

While executing the Android 13 CTS Verifier Secure Server test on a
ChromeOS device, it was observed that the Bluetooth host initiates
authentication for an RFCOMM connection after SSP completes.
When this happens, some Intel Bluetooth controllers, like AC9560, would
disconnect with "Connection Rejected due to Security Reasons (0x0e)".
Historically, BlueZ did not mandate this authentication while an
authenticated combination key was already in use for the connection.
This behavior was changed since commit 7b5a9241b7
("Bluetooth: Introduce requirements for security level 4").
So, this patch addresses the aforementioned disconnection issue by
restoring the previous behavior.

This reverts commit e44df26647.
Users reported regressions due to enabling multi-grained timestamps
unconditionally. As no clear consensus on a solution has come up and the
discussion has gone back to the drawing board revert the infrastructure
changes for. If it isn't code that's here to stay, make it go away.

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

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.

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.

Triggers a splat from nf core on next table delete because we lose

The above should have table in *active* state, but in fact no

There are some attributes added by vxlan_fill_info() which are not
accounted for in vxlan_get_size(). Add them.
I didn't find a way to trigger an actual problem from this miscalculation
since there is usually extra space in netlink size calculations like
if_nlmsg_size(); but maybe I just didn't search long enough.

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.

Playback via headphone will get EQ filter processing.
