Indicate next PN update using update_pn flag in macsec_context.
Offloaded MACsec implementations does not know whether or not the
MACSEC_SA_ATTR_PN attribute was passed for an SA update and assume
that next PN should always updated, but this is not always true.
The PN can be reset to its initial value using the following command:
$ ip macsec set macsec0 tx sa 0 off #octeontx2-pf case
Or, the update PN command will succeed even if the driver does not support
PN updates.
$ ip macsec set macsec0 tx sa 0 pn 1 on #mscc phy driver case
Comparing the initial PN with the new PN value is not a solution. When
the user updates the PN using its initial value the command will
succeed, even if the driver does not support it. Like this:
$ ip macsec add macsec0 tx sa 0 pn 1 on key 00 \
ead3664f508eb06c40ac7104cdae4ce5
$ ip macsec set macsec0 tx sa 0 pn 1 on #mlx5 case

Handle the case when GSO SKB linear length is too large.
MANA NIC requires GSO packets to put only the header part to SGE0,
otherwise the TX queue may stop at the HW level.
So, use 2 SGEs for the skb linear part which contains more than the
packet header.

This commit fixes quick-ack counting so that it only considers that a
quick-ack has been provided if we are sending an ACK that newly
acknowledges data.
The code was erroneously using the number of data segments in outgoing
skbs when deciding how many quick-ack credits to remove. This logic
does not make sense, and could cause poor performance in
request-response workloads, like RPC traffic, where requests or
responses can be multi-segment skbs.
When a TCP connection decides to send N quick-acks, that is to
accelerate the cwnd growth of the congestion control module
controlling the remote endpoint of the TCP connection. That quick-ack
decision is purely about the incoming data and outgoing ACKs. It has
nothing to do with the outgoing data or the size of outgoing data.
And in particular, an ACK only serves the intended purpose of allowing
the remote congestion control to grow the congestion window quickly if
the ACK is ACKing or SACKing new data.
The fix is simple: only count packets as serving the goal of the
quickack mechanism if they are ACKing/SACKing new data. We can tell
whether this is the case by checking inet_csk_ack_scheduled(), since
we schedule an ACK exactly when we are ACKing/SACKing new data.

After deleting an interface address in fib_del_ifaddr(), the function
scans the fib_info list for stray entries and calls fib_flush() and
fib_table_flush(). Then the stray entries will be deleted silently and no
RTM_DELROUTE notification will be sent.
This lack of notification can make routing daemons, or monitor like
`ip monitor route` miss the routing changes. e.g.
+ ip link add dummy1 type dummy
+ ip link add dummy2 type dummy
+ ip link set dummy1 up
+ ip link set dummy2 up
+ ip addr add 192.168.5.5/24 dev dummy1
+ ip route add 7.7.7.0/24 dev dummy2 src 192.168.5.5
+ ip -4 route
7.7.7.0/24 dev dummy2 scope link src 192.168.5.5
192.168.5.0/24 dev dummy1 proto kernel scope link src 192.168.5.5
+ ip monitor route
+ ip addr del 192.168.5.5/24 dev dummy1
Deleted 192.168.5.0/24 dev dummy1 proto kernel scope link src 192.168.5.5
Deleted broadcast 192.168.5.255 dev dummy1 table local proto kernel scope link src 192.168.5.5
Deleted local 192.168.5.5 dev dummy1 table local proto kernel scope host src 192.168.5.5
As Ido reminded, fib_table_flush() isn't only called when an address is
deleted, but also when an interface is deleted or put down. The lack of
notification in these cases is deliberate. And commit 7c6bb7d2faaf
("net/ipv6: Add knob to skip DELROUTE message on device down") introduced
a sysctl to make IPv6 behave like IPv4 in this regard. So we can't send
the route delete notify blindly in fib_table_flush().
To fix this issue, let's add a new flag in "struct fib_info" to track the
deleted prefer source address routes, and only send notify for them.
After update:
+ ip monitor route
+ ip addr del 192.168.5.5/24 dev dummy1
Deleted 192.168.5.0/24 dev dummy1 proto kernel scope link src 192.168.5.5

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.

netfilter pull request 23-09-13
====================
The following patchset contains Netfilter fixes for net:
1) Do not permit to remove rules from chain binding, otherwise
double rule release is possible, triggering UaF. This rule
deletion support does not make sense and userspace does not use
this. Problem exists since the introduction of chain binding support.
2) rbtree GC worker only collects the elements that have expired.
This operation is not destructive, therefore, turn write into
read spinlock to avoid datapath contention due to GC worker run.
This was not fixed in the recent GC fix batch in the 6.5 cycle.
3) pipapo set backend performs sync GC, therefore, catchall elements
must use sync GC queue variant. This bug was introduced in the
6.5 cycle with the recent GC fixes.
4) Stop GC run if memory allocation fails in pipapo set backend,
otherwise access to NULL pointer to GC transaction object might
occur. This bug was introduced in the 6.5 cycle with the recent
GC fixes.
5) rhash GC run uses an iterator that might hit EAGAIN to rewind,
triggering double-collection of the same element. This bug was
introduced in the 6.5 cycle with the recent GC fixes.
6) Do not permit to remove elements in anonymous sets, this type of
sets are populated once and then bound to rules. This fix is
similar to the chain binding patch coming first in this batch.
API permits since the very beginning but it has no use case from
userspace.

Andrei Vagin reported bind() regression with strace logs.
If we bind() a TCPv6 socket to ::FFFF:0.0.0.0 and then bind() a TCPv4
socket to 127.0.0.1, the 2nd bind() should fail but now succeeds.
from socket import *
s1 = socket(AF_INET6, SOCK_STREAM)
s1.bind(('::ffff:0.0.0.0', 0))
s2 = socket(AF_INET, SOCK_STREAM)
s2.bind(('127.0.0.1', s1.getsockname()[1]))
During the 2nd bind(), if tb->family is AF_INET6 and sk->sk_family is
AF_INET in inet_bind2_bucket_match_addr_any(), we still need to check
if tb has the v4-mapped-v6 wildcard address.
The example above does not work after commit 5456262d2baa ("net: Fix
incorrect address comparison when searching for a bind2 bucket"), but
the blamed change is not the commit.
Before the commit, the leading zeros of ::FFFF:0.0.0.0 were treated
as 0.0.0.0, and the sequence above worked by chance. Technically, this
case has been broken since bhash2 was introduced.
Note that if we bind() two sockets to 127.0.0.1 and then ::FFFF:0.0.0.0,
the 2nd bind() fails properly because we fall back to using bhash to
detect conflicts for the v4-mapped-v6 address.

Max Schulze reports crashes with brcmfmac. The reason seems
to be a race between userspace removing the CQM config and
the driver calling cfg80211_cqm_rssi_notify(), where if the
data is freed while cfg80211_cqm_rssi_notify() runs it will
crash since it assumes wdev->cqm_config is set. This can't
be fixed with a simple non-NULL check since there's nothing
we can do for locking easily, so use RCU instead to protect
the pointer, but that requires pulling the updates out into
an asynchronous worker so they can sleep and call back into
the driver.
Since we need to change the free anyway, also change it to
go back to the old settings if changing the settings fails.

When connect to MLO AP with more than one link, and the assoc response of
AP is not success, then cfg80211_unhold_bss() is not called for all the
links' cfg80211_bss except the primary link which means the link used by
the latest successful association request. Thus the hold value of the
cfg80211_bss is not reset to 0 after the assoc fail, and then the
__cfg80211_unlink_bss() will not be called for the cfg80211_bss by
__cfg80211_bss_expire().
Then the AP always looks exist even the AP is shutdown or reconfigured
to another type, then it will lead error while connecting it again.
The detail info are as below.
When connect with muti-links AP, cfg80211_hold_bss() is called by
cfg80211_mlme_assoc() for each cfg80211_bss of all the links. When
assoc response from AP is not success(such as status_code==1), the
ieee80211_link_data of non-primary link(sdata->link[link_id]) is NULL
because ieee80211_assoc_success()->ieee80211_vif_update_links() is
not called for the links.
Then struct cfg80211_rx_assoc_resp resp in cfg80211_rx_assoc_resp() and
struct cfg80211_connect_resp_params cr in __cfg80211_connect_result()
will only have the data of the primary link, and finally function
cfg80211_connect_result_release_bsses() only call cfg80211_unhold_bss()
for the primary link. Then cfg80211_bss of the other links will never free
because its hold is always > 0 now.
Hence assign value for the bss and status from assoc_data since it is
valid for this case. Also assign value of addr from assoc_data when the
link is NULL because the addrs of assoc_data and link both represent the
local link addr and they are same value for success connection.

Route hints when the nexthop is part of a multipath group causes packets
in the same receive batch to be sent to the same nexthop irrespective of
the multipath hash of the packet. So, do not extract route hint for
packets whose destination is part of a multipath group.
A new SKB flag IPSKB_MULTIPATH is introduced for this purpose, set the
flag when route is looked up in ip_mkroute_input() and use it in
ip_extract_route_hint() to check for the existence of the flag.

Long ago we set out to remove the kitchen sink on kernel/sysctl.c arrays and
placings sysctls to their own sybsystem or file to help avoid merge conflicts.
Matthew Wilcox pointed out though that if we're going to do that we might as
well also *save* space while at it and try to remove the extra last sysctl
entry added at the end of each array, a sentintel, instead of bloating the
kernel by adding a new sentinel with each array moved.
Doing that was not so trivial, and has required slowing down the moves of
kernel/sysctl.c arrays and measuring the impact on size by each new move.
The complex part of the effort to help reduce the size of each sysctl is being
done by the patient work of el señor Don Joel Granados. A lot of this is truly
painful code refactoring and testing and then trying to measure the savings of
each move and removing the sentinels. Although Joel already has code which does
most of this work, experience with sysctl moves in the past shows is we need to
be careful due to the slew of odd build failures that are possible due to the
amount of random Kconfig options sysctls use.
To that end Joel's work is split by first addressing the major housekeeping
needed to remove the sentinels, which is part of this merge request. The rest
of the work to actually remove the sentinels will be done later in future
kernel releases.
At first I was only going to send his first 7 patches of his patch series,
posted 1 month ago, but in retrospect due to the testing the changes have
received in linux-next and the minor changes they make this goes with the
entire set of patches Joel had planned: just sysctl house keeping. There are
networking changes but these are part of the house keeping too.
The preliminary math is showing this will all help reduce the overall build
time size of the kernel and run time memory consumed by the kernel by about
~64 bytes per array where we are able to remove each sentinel in the future.
That also means there is no more bloating the kernel with the extra ~64 bytes
per array moved as no new sentinels are created.
Most of this has been in linux-next for about a month, the last 7 patches took
a minor refresh 2 week ago based on feedback.

This commit implements defer setup support for the Broadcast Sink
scenario: By setting defer setup on a broadcast socket before calling
listen, the user is able to trigger the PA sync and BIG sync procedures
separately.
This is useful if the user first wants to synchronize to the periodic
advertising transmitted by a Broadcast Source, and trigger the BIG sync
procedure later on.
If defer setup is set, once a PA sync established event arrives, a new
hcon is created and notified to the ISO layer. A child socket associated
with the PA sync connection will be added to the accept queue of the
listening socket.
Once the accept call returns the fd for the PA sync child socket, the
user should call read on that fd. This will trigger the BIG create sync
procedure, and the PA sync socket will become a listening socket itself.
When the BIG sync established event is notified to the ISO layer, the
bis connections will be added to the accept queue of the PA sync parent.
The user should call accept on the PA sync socket to get the final bis
connections.

mlx5 MACsec RoCEv2 support
From Patrisious:
This series extends previously added MACsec offload support
to cover RoCE traffic either.
In order to achieve that, we need configure MACsec with offload between
the two endpoints, like below:
REMOTE_MAC=10:70:fd:43:71:c0
* ip addr add 1.1.1.1/16 dev eth2
* ip link set dev eth2 up
* ip link add link eth2 macsec0 type macsec encrypt on
* ip macsec offload macsec0 mac
* ip macsec add macsec0 tx sa 0 pn 1 on key 00 dffafc8d7b9a43d5b9a3dfbbf6a30c16
* ip macsec add macsec0 rx port 1 address $REMOTE_MAC
* ip macsec add macsec0 rx port 1 address $REMOTE_MAC sa 0 pn 1 on key 01 ead3664f508eb06c40ac7104cdae4ce5
* ip addr add 10.1.0.1/16 dev macsec0
* ip link set dev macsec0 up
And in a similar manner on the other machine, while noting the keys order
would be reversed and the MAC address of the other machine.
RDMA traffic is separated through relevant GID entries and in case
of IP ambiguity issue - meaning we have a physical GIDs and a MACsec
GIDs with the same IP/GID, we disable our physical GID in order
to force the user to only use the MACsec GID.

netfilter updates for net
This PR contains nf_tables updates for your *net* tree.
First patch fixes table validation, I broke this in 6.4 when tracking
validation state per table, reported by Pablo, fixup from myself.
Second patch makes sure objects waiting for memory release have been
released, this was broken in 6.1, patch from Pablo Neira Ayuso.
Patch three is a fix-for-fix from previous PR: In case a transaction
gets aborted, gc sequence counter needs to be incremented so pending
gc requests are invalidated, from Pablo.
Same for patch 4: gc list needs to use gc list lock, not destroy lock,
also from Pablo.
Patch 5 fixes a UaF in a set backend, but this should only occur when
failslab is enabled for GFP_KERNEL allocations, broken since feature
was added in 5.6, from myself.
Patch 6 fixes a double-free bug that was also added via previous PR:

The commit 14af9963ba1e ("bonding: Support macvlans on top of tlb/rlb mode
bonds") aims to enable the use of macvlans on top of rlb bond mode. However,
the current rlb bond mode only handles ARP packets to update remote neighbor
entries. This causes an issue when a macvlan is on top of the bond, and
remote devices send packets to the macvlan using the bond's MAC address
as the destination. After delivering the packets to the macvlan, the macvlan
will rejects them as the MAC address is incorrect. Consequently, this commit
makes macvlan over bond non-functional.
To address this problem, one potential solution is to check for the presence
of a macvlan port on the bond device using netif_is_macvlan_port(bond->dev)
and return NULL in the rlb_arp_xmit() function. However, this approach
doesn't fully resolve the situation when a VLAN exists between the bond and
macvlan.
So let's just do a partial revert for commit 14af9963ba1e in rlb_arp_xmit().
As the comment said, Don't modify or load balance ARPs that do not originate
locally.

Don't queue more gc work, else we may queue the same elements multiple
times.
If an element is flagged as dead, this can mean that either the previous
gc request was invalidated/discarded by a transaction or that the previous
request is still pending in the system work queue.
The latter will happen if the gc interval is set to a very low value,
e.g. 1ms, and system work queue is backlogged.
The sets refcount is 1 if no previous gc requeusts are queued, so add
a helper for this and skip gc run if old requests are pending.
Add a helper for this and skip the gc run in this case.

We have to validate all tables in the transaction that are in
VALIDATE_DO state, the blamed commit below did not move the break
statement to its right location so we only validate one table.
Moreover, we can't init table->validate to _SKIP when a table object
is allocated.
If we do, then if a transcaction creates a new table and then
fails the transaction, nfnetlink will loop and nft will hang until
user cancels the command.
Add back the pernet state as a place to stash the last state encountered.
This is either _DO (we hit an error during commit validation) or _SKIP
(transaction passed all checks).

While looking at a bug, I got rather confused by the layout of the
'status' field in ieee80211_tx_info. Apparently, the intention is that
status_driver_data[] is used for driver specific data, and fills up the
size of the union to 40 bytes, just like the other ones.
This is indeed what actually happens, but only because of the
combination of two mistakes:
- "void *status_driver_data[18 / sizeof(void *)];" is intended
to be 18 bytes long but is actually two bytes shorter because of
rounding-down in the division, to a multiple of the pointer
size (4 bytes or 8 bytes).
- The other fields combined are intended to be 22 bytes long, but
are actually 24 bytes because of padding in front of the
unaligned tx_time member, and in front of the pointer array.
The two mistakes cancel out. so the size ends up fine, but it seems
more helpful to make this explicit, by having a multiple of 8 bytes
in the size calculation and explicitly describing the padding.

Merge tag 'wireless-2023-08-22' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless
Johannes Berg says:
====================
Two fixes:
- reorder buffer filter checks can cause bad shift/UBSAN
warning with newer HW, avoid the check (mac80211)
- add Kconfig dependency for iwlwifi for PTP clock usage
* tag 'wireless-2023-08-22' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless:
wifi: mac80211: limit reorder_buf_filtered to avoid UBSAN warning
wifi: iwlwifi: mvm: add dependency for PTP clock

When the ifdown function in the dst_ops structure is referenced, the input
parameter 'how' is always true. In the current implementation of the
ifdown interface, ip6_dst_ifdown does not use the input parameter 'how',
xfrm6_dst_ifdown and xfrm4_dst_ifdown functions use the input parameter
'unregister'. But false judgment on 'unregister' in xfrm6_dst_ifdown and
xfrm4_dst_ifdown is false, so remove the input parameter 'how' in ifdown
function.
