Since
commit e6e771b3d897 ("s390/qeth: detach netdevice while card is offline")
there was a timing window during recovery, that qeth_query_card_info could
be sent to the card, even before it was ready for it, leading to a failing
card recovery. There is evidence that this window was hit, as not all
callers of get_link_ksettings() check for netif_device_present.
Use cached values in qeth_get_link_ksettings(), instead of calling
qeth_query_card_info() and falling back to default values in case it
fails. Link info is already updated when the card goes online, e.g. after
STARTLAN (physical link up). Set the link info to default values, when the
card goes offline or at STOPLAN (physical link down). A follow-on patch
will improve values reported for link down.

There are use-after-free bugs caused by tst_timer. The root cause
is that there are no functions to stop tst_timer in idt77252_exit().
One of the possible race conditions is shown below:
(thread 1) | (thread 2)
| idt77252_init_one
| init_card
| fill_tst
| mod_timer(&card->tst_timer, ...)
idt77252_exit | (wait a time)
| tst_timer
|
| ...
kfree(card) // FREE |
| card->soft_tst[e] // USE
The idt77252_dev is deallocated in idt77252_exit() and used in
timer handler.
This patch adds del_timer_sync() in idt77252_exit() in order that
the timer handler could be stopped before the idt77252_dev is
deallocated.

min_gate_len[tc] is supposed to track the shortest interval of
continuously open gates for a traffic class. For example, in the
following case:
TC 76543210
t0 00000001b 200000 ns
t1 00000010b 200000 ns
min_gate_len[0] and min_gate_len[1] should be 200000, while
min_gate_len[2-7] should be 0.
However what happens is that min_gate_len[0] is 200000, but
min_gate_len[1] ends up being 0 (despite gate_len[1] being 200000 at the
point where the logic detects the gate close event for TC 1).
The problem is that the code considers a "gate close" event whenever it
sees that there is a 0 for that TC (essentially it's level rather than
edge triggered). By doing that, any time a gate is seen as closed
without having been open prior, gate_len, which is 0, will be written
into min_gate_len. Once min_gate_len becomes 0, it's impossible for it
to track anything higher than that (the length of actually open
intervals).
To fix this, we make the writing to min_gate_len[tc] be edge-triggered,
which avoids writes for gates that are closed in consecutive intervals.
However what this does is it makes us need to special-case the
permanently closed gates at the end.

When a userspace application starts a blocking connect(), a CALL REQUEST
is sent, the t21 timer is started and the connect is waiting in
x25_wait_for_connection_establishment(). If then for some reason the t21
timer expires before any reaction on the assigned logical channel (e.g.
CALL ACCEPT, CLEAR REQUEST), there is sent a CLEAR REQUEST and timer
t23 is started waiting for a CLEAR confirmation. If we now receive a
CLEAR CONFIRMATION from the peer, x25_disconnect() is called in
x25_state2_machine() with reason "0", which means "normal" call
clearing. This is ok, but the parameter "reason" is used as sk->sk_err
in x25_disconnect() and sock_error(sk) is evaluated in
x25_wait_for_connection_establishment() to check if the call is still
pending. As "0" is not rated as an error, the connect will stuck here
forever.
To fix this situation, also check if the sk->sk_state changed form
TCP_SYN_SENT to TCP_CLOSE in the meantime, which is also done by
x25_disconnect().

Fixes the following warnings observed when building
CONFIG_IPV6_SEG6_LWTUNNEL=y with clang:
net/ipv6/seg6_local.o: warning: objtool: seg6_local_fill_encap() falls
through to next function seg6_local_get_encap_size()
net/ipv6/seg6_local.o: warning: objtool: seg6_local_cmp_encap() falls
through to next function input_action_end()
LLVM can fully unroll loops in seg6_local_get_encap_size() and
seg6_local_cmp_encap(). One issue in those loops is that the induction
variable is initialized to 0. The loop iterates over members of
seg6_action_params, a global array of struct seg6_action_param calling
their put() function pointer members. seg6_action_param uses an array
initializer to initialize SEG6_LOCAL_SRH and later elements, which is
the third enumeration of an anonymous union.
The guard `if (attrs & SEG6_F_ATTR(i))` may prevent this from being
called at runtime, but it would still be UB for
`seg6_action_params[0]->put` to be called; the unrolled loop will make
the initial iterations unreachable, which LLVM will later rotate to
fallthrough to the next function.
Make this more obvious that this cannot happen to the compiler by
initializing the loop induction variable to the minimum valid index that
seg6_action_params is initialized to.

rose /proc code does not serialize timer accesses.
Initial report by Bernard F6BVP Pidoux exhibits overflow amounting

Full timer access serialization would imho be overkill as rose /proc
does not enforce consistency between displayed ROSE_STATE_XYZ and
timer values during changes of state.
The patch may also fix similar behavior in ax25 /proc, ax25 ioctl
and netrom /proc as they all exhibit the same timer serialization
policy. This point has not been reported though.
The sole remaining use of ax25_display_timer - ax25 rtt valuation -

For packets scheduled to RPM and LBK, NIX_AF_PSE_CHANNEL_LEVEL[BP_LEVEL]

level: Setting NIX_AF_TL3_TL2(0..255)_LINK(0..12)_CFG[ENA] = 1 allows

Octeontx2 AF driver fixes for NPC
This patchset includes AF driver fixes wrt packet parser NPC.
Following are the changes:
Patch 1: The parser nibble configuration must be same for
TX and RX interfaces and if not fix up is applied. This fixup was
applied only for default profile currently and it has been fixed
to apply for all profiles.
Patch 2: Firmware image may not be present all times in the kernel image
and default profile is used mostly hence suppress the warning.
Patch 3: This patch fixes a corner case where NIXLF is detached but
without freeing its mcam entries which results in resource leak.
Patch 4: SMAC is overlapped with DMAC mistakenly while installing
rules based on SMAC. This patch fixes that.

do not access info->pkt when info->trace is not 1.
nft_traceinfo is not initialized, except when tracing is enabled.
The 'nft_trace_enabled' static key cannot be used for this, we must
always check info->trace first.
Pass nft_pktinfo directly to avoid this.

"net: check if protocol extracted by virtio_net_hdr_set_proto is correct"
Need test for the case when a non-standard packet (GSO without NEEDS_CSUM)
sent to the tap device causes a BUG check in the tap driver.

mptcp: Fixes for mptcp cleanup/close and a selftest
Patch 1 fixes an issue with leaking subflow sockets if there's a failure
in a CGROUP_INET_SOCK_CREATE eBPF program.
Patch 2 fixes a syzkaller-detected race at MPTCP socket close.
Patch 3 is a fix for one mode of the mptcp_connect.sh selftest.

When the selftest got added, sendfile() on mptcp sockets returned
-EOPNOTSUPP, so running 'mptcp_connect.sh -m sendfile' failed
immediately.
This is no longer the case, but the script fails anyway due to timeout.
Let the receiver know once the sender has sent all data, just like
with '-m mmap' mode.
v2: need to respect cfg_wait too, as pm_userspace.sh relied
on -m sendfile to keep the connection open (Mat Martineau)

If the mptcp socket creation fails due to a CGROUP_INET_SOCK_CREATE
eBPF program, the MPTCP protocol ends-up leaking all the subflows:
the related cleanup happens in __mptcp_destroy_sock() that is not
invoked in such code path.
Address the issue moving the subflow sockets cleanup in the
mptcp_destroy_common() helper, which is invoked in every msk cleanup
path.
Additionally get rid of the intermediate list_splice_init step, which
is an unneeded relic from the past.
The issue is present since before the reported root cause commit, but
any attempt to backport the fix before that hash will require a complete
rewrite.

The port flag isn't set to `NFP_PORT_CHANGED` when using
`ethtool -m DEVNAME` before, so the port state (e.g. interface)
cannot be updated. Therefore, it caused that `ethtool -m DEVNAME`
sometimes cannot read the correct information.
E.g. `ethtool -m DEVNAME` cannot work when load driver before plug
in optical module, as the port interface is still NONE without port
update.
Now update the port state before sending info to NIC to ensure that
port interface is correct (latest state).

Calling mdio_bus_phy_resume() with neither the PHY state machine set to
PHY_HALTED nor phydev->mac_managed_pm set to true is a good indication
that we can produce a race condition looking like this:
CPU0 CPU1
bcmgenet_resume
-> phy_resume
-> phy_init_hw
-> phy_start
-> phy_resume
phy_start_aneg()
mdio_bus_phy_resume
-> phy_resume
-> phy_write(..., BMCR_RESET)
-> usleep() -> phy_read()
with the phy_resume() function triggering a PHY behavior that might have
to be worked around with (see bf8bfc4336f7 ("net: phy: broadcom: Fix
brcm_fet_config_init()") for instance) that ultimately leads to an error
reading from the PHY.

====================
Make DSA work with bonding's ARP monitor
Since commit 2b86cb829976 ("net: dsa: declare lockless TX feature for
slave ports") in v5.7, DSA breaks the ARP monitoring logic from the
bonding driver, fact which was pointed out by Brian Hutchinson who uses
a linux-5.10.y stable kernel.
Initially I got lured by other similar hacks introduced for other
NETIF_F_LLTX drivers, which, inspired by the bonding documentation,
update the trans_start of their TX queues by hand.
However Jakub pointed out that this simply isn't a proper solution, and
after coming to think more about it, I agree, and it doesn't work
properly with DSA nor is it maintainable for the future changes I plan
for it (multiple DSA masters in a LAG).
I've tested these changes using a DSA-based setup and a veth-based
setup, using the active-backup mode and ARP monitoring, with and without
arp_validate.

This reverts commit e66e257a5d8368d9c0ba13d4630f474436533e8b. The veth
driver no longer needs these hacks which are slightly detrimential to
the fast path performance, because the bonding driver is keeping track
of TX times of ARP and NS probes by itself, which it should.
