net/mlx5e: Don't call cleanup on profile rollback failure
When profile rollback fails in mlx5e_netdev_change_profile, the netdev
profile var is left set to NULL. Avoid a crash when unloading the driver
by not calling profile->cleanup in such a case.
This was encountered while testing, with the original trigger that
the wq rescuer thread creation got interrupted (presumably due to
Ctrl+C-ing modprobe), which gets converted to ENOMEM (-12) by
mlx5e_priv_init, the profile rollback also fails for the same reason
(signal still active) so the profile is left as NULL, leading to a crash
later in _mlx5e_remove.

net/mlx5: Fix command bitmask initialization
Command bitmask have a dedicated bit for MANAGE_PAGES command, this bit
isn't Initialize during command bitmask Initialization, only during
MANAGE_PAGES.
In addition, mlx5_cmd_trigger_completions() is trying to trigger
completion for MANAGE_PAGES command as well.
Hence, in case health error occurred before any MANAGE_PAGES command
have been invoke (for example, during mlx5_enable_hca()),
mlx5_cmd_trigger_completions() will try to trigger completion for
MANAGE_PAGES command, which will result in null-ptr-deref error.[1]
Fix it by Initialize command bitmask correctly.
While at it, re-write the code for better understanding.

Currently, mlx5 driver does not enforce vector index to be lower than
the maximum number of supported completion vectors when requesting a
new completion EQ. Thus, mlx5_comp_eqn_get() fails when trying to

To prevent the case above, enforce that vector index value is

That's because 'subflow' is used just after 'mptcp_close_ssk(subflow)',
which will initiate the release of its memory. Even if it is very likely
the release and the re-utilisation will be done later on, it is of
course better to avoid any issues and read the content of 'subflow'
before closing it.

vmxnet3: Fix packet corruption in vmxnet3_xdp_xmit_frame
Andrew and Nikolay reported connectivity issues with Cilium's service
load-balancing in case of vmxnet3.
If a BPF program for native XDP adds an encapsulation header such as
IPIP and transmits the packet out the same interface, then in case
of vmxnet3 a corrupted packet is being sent and subsequently dropped
on the path.
vmxnet3_xdp_xmit_frame() which is called e.g. via vmxnet3_run_xdp()
through vmxnet3_xdp_xmit_back() calculates an incorrect DMA address:
page = virt_to_page(xdpf->data);
tbi->dma_addr = page_pool_get_dma_addr(page) +
VMXNET3_XDP_HEADROOM;
dma_sync_single_for_device(&adapter->pdev->dev,
tbi->dma_addr, buf_size,
DMA_TO_DEVICE);
The above assumes a fixed offset (VMXNET3_XDP_HEADROOM), but the XDP
BPF program could have moved xdp->data. While the passed buf_size is
correct (xdpf->len), the dma_addr needs to have a dynamic offset which
can be calculated as xdpf->data - (void *)xdpf, that is, xdp->data -
xdp->data_hard_start.

net: dsa: vsc73xx: fix reception from VLAN-unaware bridges
Similar to the situation described for sja1105 in commit
1f9fc48fd302
("net: dsa: sja1105: fix reception from VLAN-unaware bridges"), the
vsc73xx driver uses tag_8021q and doesn't need the ds->untag_bridge_pvid
request. In fact, this option breaks packet reception.
The ds->untag_bridge_pvid option strips VLANs from packets received on
VLAN-unaware bridge ports. But those VLANs should already be stripped
by tag_vsc73xx_8021q.c as part of vsc73xx_rcv() - they are not VLANs in
VLAN-unaware mode, but DSA tags. Thus, dsa_software_vlan_untag() tries
to untag a VLAN that doesn't exist, corrupting the packet.

net: ravb: Only advertise Rx/Tx timestamps if hardware supports it
Recent work moving the reporting of Rx software timestamps to the core
[1] highlighted an issue where hardware time stamping was advertised
for the platforms where it is not supported.
Fix this by covering advertising support for hardware timestamps only if
the hardware supports it. Due to the Tx implementation in RAVB software
Tx timestamping is also only considered if the hardware supports
hardware timestamps. This should be addressed in future, but this fix
only reflects what the driver currently implements.

udp: Compute L4 checksum as usual when not segmenting the skb
If:
1) the user requested USO, but
2) there is not enough payload for GSO to kick in, and
3) the egress device doesn't offer checksum offload, then
we want to compute the L4 checksum in software early on.
In the case when we are not taking the GSO path, but it has been requested,
the software checksum fallback in skb_segment doesn't get a chance to
compute the full checksum, if the egress device can't do it. As a result we
end up sending UDP datagrams with only a partial checksum filled in, which
the peer will discard.

genetlink: hold RCU in genlmsg_mcast()
While running net selftests with CONFIG_PROVE_RCU_LIST=y I saw
one lockdep splat [1].
genlmsg_mcast() uses for_each_net_rcu(), and must therefore hold RCU.
Instead of letting all callers guard genlmsg_multicast_allns()
with a rcu_read_lock()/rcu_read_unlock() pair, do it in genlmsg_mcast().
This also means the @flags parameter is useless, we need to always use

tcp/dccp: Don't use timer_pending() in reqsk_queue_unlink().
Martin KaFai Lau reported use-after-free [0] in reqsk_timer_handler().
"""
We are seeing a use-after-free from a bpf prog attached to
trace_tcp_retransmit_synack. The program passes the req->sk to the
bpf_sk_storage_get_tracing kernel helper which does check for null

"""
The commit
83fccfc3940c ("inet: fix potential deadlock in
reqsk_queue_unlink()") added timer_pending() in reqsk_queue_unlink() not
to call del_timer_sync() from reqsk_timer_handler(), but it introduced a
small race window.
Before the timer is called, expire_timers() calls detach_timer(timer, true)
to clear timer->entry.pprev and marks it as not pending.
If reqsk_queue_unlink() checks timer_pending() just after expire_timers()
calls detach_timer(), TCP will miss del_timer_sync(); the reqsk timer will
continue running and send multiple SYN+ACKs until it expires.
The reported UAF could happen if req->sk is close()d earlier than the timer
expiration, which is 63s by default.
The scenario would be
1. inet_csk_complete_hashdance() calls inet_csk_reqsk_queue_drop(),
but del_timer_sync() is missed
2. reqsk timer is executed and scheduled again
3. req->sk is accept()ed and reqsk_put() decrements rsk_refcnt, but
reqsk timer still has another one, and inet_csk_accept() does not
clear req->sk for non-TFO sockets
4. sk is close()d
5. reqsk timer is executed again, and BPF touches req->sk
Let's not use timer_pending() by passing the caller context to
__inet_csk_reqsk_queue_drop().
Note that reqsk timer is pinned, so the issue does not happen in most
use cases. [1]

Pull ring-buffer fixes from Steven Rostedt:
- Fix ref counter of buffers assigned at boot up
A tracing instance can be created from the kernel command line. If it
maps to memory, it is considered permanent and should not be deleted,
or bad things can happen. If it is not mapped to memory, then the
user is fine to delete it via rmdir from the instances directory. But
the ref counts assumed 0 was free to remove and greater than zero was
not. But this was not the case. When an instance is created, it
should have the reference of 1, and if it should not be removed, it
must be greater than 1. The boot up code set normal instances with a
ref count of 0, which could get removed if something accessed it and
then released it. And memory mapped instances had a ref count of 1
which meant it could be deleted, and bad things happen. Keep normal
instances ref count as 1, and set memory mapped instances ref count
to 2.
- Protect sub buffer size (order) updates from other modifications
When a ring buffer is changing the size of its sub-buffers, no other
operations should be performed on the ring buffer. That includes
reading it. But the locking only grabbed the buffer->mutex that keeps
some operations from touching the ring buffer. It also must hold the
cpu_buffer->reader_lock as well when updates happen as other paths
use that to do some operations on the ring buffer.

the picking the right port which have been extracted into three new

As noted by Cong Wang, the splat is false positive, but the code
path leading to the report is an unexpected one: a client is
attempting an MPC handshake towards the in-kernel listener created
by the in-kernel PM for a port based signal endpoint.
Such connection will be never accepted; many of them can make the
listener queue full and preventing the creation of MPJ subflow via
such listener - its intended role.
Explicitly detect this scenario at initial-syn time and drop the
incoming MPC request.

net: macb: Avoid 20s boot delay by skipping MDIO bus registration for fixed-link PHY
A boot delay was introduced by commit
79540d133ed6 ("net: macb: Fix
handling of fixed-link node"). This delay was caused by the call to
`mdiobus_register()` in cases where a fixed-link PHY was present. The
MDIO bus registration triggered unnecessary PHY address scans, leading
to a 20-second delay due to attempts to detect Clause 45 (C45)
compatible PHYs, despite no MDIO bus being attached.
The commit
79540d133ed6 ("net: macb: Fix handling of fixed-link node")
was originally introduced to fix a regression caused by commit
7897b071ac3b4 ("net: macb: convert to phylink"), which caused the driver
to misinterpret fixed-link nodes as PHY nodes. This resulted in warnings
like:
mdio_bus
f0028000.ethernet-
ffffffff: fixed-link has invalid PHY address
mdio_bus
f0028000.ethernet-
ffffffff: scan phy fixed-link at address 0
...
mdio_bus
f0028000.ethernet-
ffffffff: scan phy fixed-link at address 31
This patch reworks the logic to avoid registering and allocation of the
MDIO bus when:
- The device tree contains a fixed-link node.
- There is no "mdio" child node in the device tree.
If a child node named "mdio" exists, the MDIO bus will be registered to
support PHYs attached to the MACB's MDIO bus. Otherwise, with only a
fixed-link, the MDIO bus is skipped.
Tested on a sama5d35 based system with a ksz8863 switch attached to
macb0.

macsec: don't increment counters for an unrelated SA
On RX, we shouldn't be incrementing the stats for an arbitrary SA in
case the actual SA hasn't been set up. Those counters are intended to
track packets for their respective AN when the SA isn't currently
configured. Due to the way MACsec is implemented, we don't keep
counters unless the SA is configured, so we can't track those packets,
and those counters will remain at 0.
The RXSC's stats keeps track of those packets without telling us which
AN they belonged to. We could add counters for non-existent SAs, and
then find a way to integrate them in the dump to userspace, but I
don't think it's worth the effort.

tegra-mgbe
6800000.ethernet: timeout waiting for link to become ready
As per the recommendation from the Tegra hardware design team, fix this
issue by:
- clearing the PHY_RDY bit before setting the CDR_RESET bit and then
setting PHY_RDY bit before clearing CDR_RESET bit. This ensures valid
data is present at UPHY RX inputs before starting the CDR lock.
- adding the required delays when bringing up the UPHY lane. Note we
need to use delays here because there is no alternative, such as
polling, for these cases. Using the usleep_range() instead of ndelay()
as sleeping is preferred over busy wait loop.
Without this change we would see link failures on boot sometimes as
often as 1 in 5 boots. With this fix we have not observed any failures
in over 1000 boots.

posix-clock: Fix missing timespec64 check in pc_clock_settime()
As Andrew pointed out, it will make sense that the PTP core
checked timespec64 struct's tv_sec and tv_nsec range before calling
ptp->info->settime64().
As the man manual of clock_settime() said, if tp.tv_sec is negative or
tp.tv_nsec is outside the range [0..999,999,999], it should return EINVAL,
which include dynamic clocks which handles PTP clock, and the condition is
consistent with timespec64_valid(). As Thomas suggested, timespec64_valid()
only check the timespec is valid, but not ensure that the time is
in a valid range, so check it ahead using timespec64_valid_strict()
in pc_clock_settime() and return -EINVAL if not valid.
There are some drivers that use tp->tv_sec and tp->tv_nsec directly to
write registers without validity checks and assume that the higher layer
has checked it, which is dangerous and will benefit from this, such as
hclge_ptp_settime(), igb_ptp_settime_i210(), _rcar_gen4_ptp_settime(),
and some drivers can remove the checks of itself.

bcachefs: Fix sysfs warning in fstests generic/730,731
sysfs warns if we're removing a symlink from a directory that's no
longer in sysfs; this is triggered by fstests generic/730, which
simulates hot removal of a block device.
This patch is however not a correct fix, since checking
kobj->state_in_sysfs on a kobj owned by another subsystem is racy.
A better fix would be to add the appropriate check to
sysfs_remove_link() - and sysfs_create_link() as well.
But kobject_add_internal()/kobject_del() do not as of today have locking
that would support that.
Note that the block/holder.c code appears to be subject to this race as
well.

bcachefs: Handle race between stripe reuse, invalidate_stripe_to_dev
When creating a new stripe, we may reuse an existing stripe that has
some empty and some nonempty blocks.
Generally, the existing stripe won't change underneath us - except for
block sector counts, which we copy to the new key in
ec_stripe_key_update.
But the device removal path can now invalidate stripe pointers to a
device, and that can race with stripe reuse.
Change ec_stripe_key_update() to check for and resolve this
inconsistency.

parsing the pacing stats, driver has a check for "rdev->dbr_pacing". This
caused a trace when KASAN is enabled.

net: enetc: disable NAPI after all rings are disabled
When running "xdp-bench tx eno0" to test the XDP_TX feature of ENETC
on LS1028A, it was found that if the command was re-run multiple times,
Rx could not receive the frames, and the result of xdp-bench showed
that the rx rate was 0.
root@ls1028ardb:~# ./xdp-bench tx eno0
Hairpinning (XDP_TX) packets on eno0 (ifindex 3; driver fsl_enetc)
Summary 2046 rx/s 0 err,drop/s
Summary 0 rx/s 0 err,drop/s
Summary 0 rx/s 0 err,drop/s
Summary 0 rx/s 0 err,drop/s
By observing the Rx PIR and CIR registers, CIR is always 0x7FF and
PIR is always 0x7FE, which means that the Rx ring is full and can no
longer accommodate other Rx frames. Therefore, the problem is caused
by the Rx BD ring not being cleaned up.
Further analysis of the code revealed that the Rx BD ring will only
be cleaned if the "cleaned_cnt > xdp_tx_in_flight" condition is met.
Therefore, some debug logs were added to the driver and the current
values of cleaned_cnt and xdp_tx_in_flight were printed when the Rx
BD ring was full. The logs are as follows.
[ 178.762419] [XDP TX] >> cleaned_cnt:1728, xdp_tx_in_flight:2140
[ 178.771387] [XDP TX] >> cleaned_cnt:1941, xdp_tx_in_flight:2110
[ 178.776058] [XDP TX] >> cleaned_cnt:1792, xdp_tx_in_flight:2110
From the results, the max value of xdp_tx_in_flight has reached 2140.
However, the size of the Rx BD ring is only 2048. So xdp_tx_in_flight
did not drop to 0 after enetc_stop() is called and the driver does not
clear it. The root cause is that NAPI is disabled too aggressively,
without having waited for the pending XDP_TX frames to be transmitted,
and their buffers recycled, so that xdp_tx_in_flight cannot naturally
drop to 0. Later, enetc_free_tx_ring() does free those stale, unsent
XDP_TX packets, but it is not coded up to also reset xdp_tx_in_flight,
hence the manifestation of the bug.
One option would be to cover this extra condition in enetc_free_tx_ring(),
but now that the ENETC_TX_DOWN exists, we have created a window at
the beginning of enetc_stop() where NAPI can still be scheduled, but
any concurrent enqueue will be blocked. Therefore, enetc_wait_bdrs()
and enetc_disable_tx_bdrs() can be called with NAPI still scheduled,
and it is guaranteed that this will not wait indefinitely, but instead
give us an indication that the pending TX frames have orderly dropped
to zero. Only then should we call napi_disable().
This way, enetc_free_tx_ring() becomes entirely redundant and can be
dropped as part of subsequent cleanup.
The change also refactors enetc_start() so that it looks like the
mirror opposite procedure of enetc_stop().

net: enetc: disable Tx BD rings after they are empty
The Tx BD rings are disabled first in enetc_stop() and the driver
waits for them to become empty. This operation is not safe while
the ring is actively transmitting frames, and will cause the ring
to not be empty and hardware exception. As described in the NETC
block guide, software should only disable an active Tx ring after
all pending ring entries have been consumed (i.e. when PI = CI).
Disabling a transmit ring that is actively processing BDs risks
a HW-SW race hazard whereby a hardware resource becomes assigned
to work on one or more ring entries only to have those entries be
removed due to the ring becoming disabled.
When testing XDP_REDIRECT feautre, although all frames were blocked
from being put into Tx rings during ring reconfiguration, the similar
warning log was still encountered:
fsl_enetc 0000:00:00.2 eno2: timeout for tx ring #6 clear
fsl_enetc 0000:00:00.2 eno2: timeout for tx ring #7 clear
The reason is that when there are still unsent frames in the Tx ring,
disabling the Tx ring causes the remaining frames to be unable to be
sent out. And the Tx ring cannot be restored, which means that even
if the xdp program is uninstalled, the Tx frames cannot be sent out
anymore. Therefore, correct the operation order in enect_start() and
enect_stop().
