Pull pidfd fix from Christian Brauner:
"This fixes a problem reported by lockdep when installing a pidfd via
fd_install() with siglock and the tasklisk write lock held in
copy_process() when calling clone()/clone3() with CLONE_PIDFD.
Originally a pidfd was created prior to holding any of these locks but
this required a call to ksys_close(). So quite some time ago in
6fd2fe494b17 ("copy_process(): don't use ksys_close() on cleanups") we
switched to a get_unused_fd_flags() + fd_install() model.
As part of that we moved fd_install() as late as possible. This was
done for two main reasons. First, because we needed to ensure that we
call fd_install() past the point of no return as once that's called
the fd is live in the task's file table. Second, because we tried to
ensure that the fd is visible in /proc/<pid>/fd/<pidfd> right when the
task is visible.
This fix moves the fd_install() to an even later point which means
that a task will be visible in proc while the pidfd isn't yet under
/proc/<pid>/fd/<pidfd>.
While this is a user visible change it's very unlikely that this will
have any impact. Nobody should be relying on that and if they do we
need to come up with something better but again, it's doubtful this is
relevant"

Pull ucounts fixes from Eric Biederman:
"Michal Koutný recently found some bugs in the enforcement of

In this set of patches I have developed a very conservative approach
changing only what is necessary to fix the bugs that I can see
clearly. Cleanups and anything that is making the code more consistent
can follow after we have the code working as it has historically.
The problem is not so much inconsistencies (although those exist) but
that it is very difficult to figure out what the code should be doing
in the case of RLIMIT_NPROC.
All other rlimits are only enforced where the resource is acquired
(allocated). RLIMIT_NPROC by necessity needs to be enforced in an
additional location, and our current implementation stumbled it's way
into that implementation"

To install a livepatch, first flash the package to NVM, and then
activate the patch through the "HWRM_FW_LIVEPATCH" fw command.
To uninstall a patch from NVM, flash the removal package and then
activate it through the "HWRM_FW_LIVEPATCH" fw command.
The "HWRM_FW_LIVEPATCH" fw command has to consider following scenarios:
1. no patch in NVM and no patch active. Do nothing.
2. patch in NVM, but not active. Activate the patch currently in NVM.
3. patch is not in NVM, but active. Deactivate the patch.
4. patch in NVM and the patch active. Do nothing.
Fix the code to handle these scenarios during devlink "fw_activate".
To install and activate a live patch:
devlink dev flash pci/0000:c1:00.0 file thor_patch.pkg
devlink -f dev reload pci/0000:c1:00.0 action fw_activate limit no_reset
To remove and deactivate a live patch:
devlink dev flash pci/0000:c1:00.0 file thor_patch_rem.pkg
devlink -f dev reload pci/0000:c1:00.0 action fw_activate limit no_reset

When polling for the firmware message response, we first poll for the
response message header. Once the valid length is detected in the
header, we poll for the valid bit at the end of the message which
signals DMA completion. Normally, this poll time for DMA completion
is extremely short (0 to a few usec). But on some devices under some
rare conditions, it can be up to about 20 msec.
Increase this delay to 50 msec and use udelay() for the first 10 usec
for the common case, and usleep_range() beyond that.
Also, change the error message to include the above delay time when
printing the timeout value.

During ifdown, we call bnxt_inv_fw_health_reg() which will clear
both the status_reliable and resets_reliable flags if these
registers are mapped. This is correct because a FW reset during
ifdown will clear these register mappings. If we detect that FW
has gone through reset during the next ifup, we will remap these
registers.
But during normal ifup with no FW reset, we need to restore the
resets_reliable flag otherwise we will not show the reset counter
during devlink diagnose.

In the current code, we setup the port to PHY or MAC loopback mode
and then transmit a test broadcast packet for the loopback test. This
scheme fails sometime if the port is shared with management firmware
that can also send packets. The driver may receive the management
firmware's packet and the test will fail when the contents don't
match the test packet.
Change the test packet to use it's own MAC address as the destination
and setup the port to only receive it's own MAC address. This should
filter out other packets sent by management firmware.

If the DSA master doesn't support IFF_UNICAST_FLT, then the following
call path is possible:
dsa_slave_switchdev_event_work
-> dsa_port_host_fdb_add
-> dev_uc_add
-> __dev_set_rx_mode
-> __dev_set_promiscuity
Since the blamed commit, dsa_slave_switchdev_event_work() no longer
holds rtnl_lock(), which triggers the ASSERT_RTNL() from
__dev_set_promiscuity().
Taking rtnl_lock() around dev_uc_add() is impossible, because all the
code paths that call dsa_flush_workqueue() do so from contexts where the
rtnl_mutex is already held - so this would lead to an instant deadlock.
dev_uc_add() in itself doesn't require the rtnl_mutex for protection.
There is this comment in __dev_set_rx_mode() which assumes so:
/* Unicast addresses changes may only happen under the rtnl,
* therefore calling __dev_set_promiscuity here is safe.
*/
but it is from commit 4417da668c00 ("[NET]: dev: secondary unicast
address support") dated June 2007, and in the meantime, commit
f1f28aa3510d ("netdev: Add addr_list_lock to struct net_device."), dated
July 2008, has added &dev->addr_list_lock to protect this instead of the
global rtnl_mutex.
Nonetheless, __dev_set_promiscuity() does assume rtnl_mutex protection,
but it is the uncommon path of what we typically expect dev_uc_add()
to do. So since only the uncommon path requires rtnl_lock(), just check
ahead of time whether dev_uc_add() would result into a call to
__dev_set_promiscuity(), and handle that condition separately.
DSA already configures the master interface to be promiscuous if the
tagger requires this. We can extend this to also cover the case where
the master doesn't handle dev_uc_add() (doesn't support IFF_UNICAST_FLT),
and on the premise that we'd end up making it promiscuous during
operation anyway, either if a DSA slave has a non-inherited MAC address,
or if the bridge notifies local FDB entries for its own MAC address, the
address of a station learned on a foreign port, etc.

Commit b3612ccdf284 ("net: dsa: microchip: implement multi-bridge support")
plugged a packet leak between ports that were members of different bridges.
Unfortunately, this broke another use case, namely that of more than two
ports that are members of the same bridge.
After that commit, when a port is added to a bridge, hardware bridging
between other member ports of that bridge will be cleared, preventing
packet exchange between them.
Fix by ensuring that the Port VLAN Membership bitmap includes any existing
ports in the bridge, not just the port being added.

All functions defined as static inline in net/checksum.h are
meant to be inlined for performance reason.
But since commit ac7c3e4ff401 ("compiler: enable
CONFIG_OPTIMIZE_INLINING forcibly") the compiler is allowed to
uninline functions when it wants.
Fair enough in the general case, but for tiny performance critical
checksum helpers that's counter-productive.
The problem mainly arises when selecting CONFIG_CC_OPTIMISE_FOR_SIZE,
Those helpers being 'static inline' in header files you suddenly find
them duplicated many times in the resulting vmlinux.

Since commit 2843ff6f36db ("mptcp: remote addresses fullmesh"), an
MPTCP client can attempt creating multiple MPJ subflow simultaneusly.
In such scenario the server, when syncookies are enabled, could end-up
accepting incoming MPJ syn even above the configured subflow limit, as
the such limit can be enforced in a reliable way only after the subflow
creation. In case of syncookie, only after the 3rd ack reception.
As a consequence the related self-tests case sporadically fails, as it
verify that the server always accept the expected number of MPJ syn.
Address the issues relaxing the MPJ syn number constrain. Note that the
check on the accepted number of MPJ 3rd ack still remains intact.

The MPTCP in kernel path manager has some constraints on incoming
addresses announce processing, so that in edge scenarios it can
end-up dropping (ignoring) some of such announces.
The above is not very limiting in practice since such scenarios are
very uncommon and MPTCP will recover due to ADD_ADDR retransmissions.
This patch adds a few MIB counters to account for such drop events
to allow easier introspection of the critical scenarios.

If an MPTCP endpoint received multiple consecutive incoming
ADD_ADDR options, mptcp_pm_add_addr_received() can overwrite
the current remote address value after the PM lock is released
in mptcp_pm_nl_add_addr_received() and before such address
is echoed.

After commit a88c9e496937 ("mptcp: do not block subflows
creation on errors"), if a signal address races with a failing
subflow creation, the subflow creation failure control path
can trigger the selection of the next address to be announced
while the current announced is still pending.
The above will cause the unintended suppression of the ADD_ADDR
announce.
Fix the issue skipping the to-be-suppressed announce before it
will mark an endpoint as already used. The relevant announce
will be triggered again when the current one will complete.

ida_simple_get() returns an id between min (0) and max (NFP_MAX_MAC_INDEX)
inclusive.
So NFP_MAX_MAC_INDEX (0xff) is a valid id.
In order for the error handling path to work correctly, the 'invalid'

inclusive.
So set it to -1.

Booting a MACCHIATObin with 5.17, the system OOPs with

The tegra186 GPIO driver makes the assumption that the pointer
returned by irq_data_get_irq_chip_data() is a pointer to a
tegra_gpio structure. Unfortunately, it is actually a pointer
to the inner gpio_chip structure, as mandated by the gpiolib
infrastructure. Nice try.
The saving grace is that the gpio_chip is the first member of
tegra_gpio, so the bug has gone undetected since... forever.
Fix it by performing a container_of() on the pointer. This results
in no additional code, and makes it possible to understand how
the whole thing works.

When we switch from emulated PS/2 to native (RMI4 or Elan) protocols, we
create SMBus companion devices that are attached to I2C/SMBus controllers.
However, when suspending and resuming, we also need to make sure that we
take into account the PS/2 device they are associated with, so that PS/2
device is suspended after the companion and resumed before it, otherwise
companions will not work properly. Before I2C devices were marked for
asynchronous suspend/resume, this ordering happened naturally, but now we
need to enforce it by establishing device links, with PS/2 devices being
suppliers and SMBus companions being consumers.

Commit c503e63200c6 ("ice: Stop processing VF messages during teardown")
introduced a driver state flag, ICE_VF_DEINIT_IN_PROGRESS, which is
intended to prevent some issues with concurrently handling messages from
VFs while tearing down the VFs.
This change was motivated by crashes caused while tearing down and
bringing up VFs in rapid succession.
It turns out that the fix actually introduces issues with the VF driver
caused because the PF no longer responds to any messages sent by the VF
during its .remove routine. This results in the VF potentially removing
its DMA memory before the PF has shut down the device queues.
Additionally, the fix doesn't actually resolve concurrency issues within
the ice driver. It is possible for a VF to initiate a reset just prior
to the ice driver removing VFs. This can result in the remove task
concurrently operating while the VF is being reset. This results in
similar memory corruption and panics purportedly fixed by that commit.
Fix this concurrency at its root by protecting both the reset and
removal flows using the existing VF cfg_lock. This ensures that we
cannot remove the VF while any outstanding critical tasks such as a
virtchnl message or a reset are occurring.
This locking change also fixes the root cause originally fixed by commit
c503e63200c6 ("ice: Stop processing VF messages during teardown"), so we
can simply revert it.
Note that I kept these two changes together because simply reverting the
original commit alone would leave the driver vulnerable to worse race
conditions.

In switchdev mode, slow-path rules need to match all protocols, in order
to correctly redirect unfiltered or missed packets to the uplink. To set
this up for the virtual function to uplink flow, the rule that redirects
packets to the control VSI must have the tunnel type set to
ICE_SW_TUN_AND_NON_TUN. As a result of that new tunnel type being set,
ice_get_compat_fv_bitmap will select ICE_PROF_ALL. At that point all
profiles would be selected for this rule, resulting in the desired
behavior. Without this change slow-path would not work with
tunnel protocols.
