This issue was found by syzkaller.
The panic happens in br_dev_queue_push_xmit() once it receives a
corrupted skb with ETH header already pushed in linear data. When it
attempts the skb_push() call, there's not enough headroom and
skb_push() panics.
The corrupted skb is put on the queue by HSR layer, which makes a
sequence of unintended transformations when it receives a specific
corrupted HSR frame (with incomplete TAG).
Fix it by dropping and consuming frames that are not long enough to
contain both ethernet and hsr headers.
Alternative fix would be to check for enough headroom before skb_push()
in br_dev_queue_push_xmit().
In the reproducer, this is injected via AF_PACKET, but I don't easily
see why it couldn't be sent over the wire from adjacent network.
Further Details:
In the reproducer, the following network interface chain is set up:
┌────────────────┐ ┌────────────────┐
│ veth0_to_hsr ├───┤ hsr_slave0 ┼───┐
└────────────────┘ └────────────────┘ │
│ ┌──────┐
├─┤ hsr0 ├───┐
│ └──────┘ │
┌────────────────┐ ┌────────────────┐ │ │┌────────┐
│ veth1_to_hsr ┼───┤ hsr_slave1 ├───┘ └┤ │
└────────────────┘ └────────────────┘ ┌┼ bridge │
││ │
│└────────┘
│
┌───────┐ │
│ ... ├──────┘
└───────┘
To trigger the events leading up to crash, reproducer sends a corrupted
HSR frame with incomplete TAG, via AF_PACKET socket on 'veth0_to_hsr'.
The first HSR-layer function to process this frame is
hsr_handle_frame(). It and then checks if the
protocol is ETH_P_PRP or ETH_P_HSR. If it is, it calls
skb_set_network_header(skb, ETH_HLEN + HSR_HLEN), without checking that
the skb is long enough. For the crashing frame it is not, and hence the
skb->network_header and skb->mac_len fields are set incorrectly,
pointing after the end of the linear buffer.
I will call this a BUG#1 and it is what is addressed by this patch. In
the crashing scenario before the fix, the skb continues to go down the
hsr path as follows.
hsr_handle_frame() then calls this sequence
hsr_forward_skb()
fill_frame_info()
hsr->proto_ops->fill_frame_info()
hsr_fill_frame_info()
hsr_fill_frame_info() contains a check that intends to check whether the
skb actually contains the HSR header. But the check relies on the
skb->mac_len field which was erroneously setup due to BUG#1, so the
check passes and the execution continues back in the hsr_forward_skb():
hsr_forward_skb()
hsr_forward_do()
hsr->proto_ops->get_untagged_frame()
hsr_get_untagged_frame()
create_stripped_skb_hsr()
In create_stripped_skb_hsr(), a copy of the skb is created and is
further corrupted by operation that attempts to strip the HSR tag in a
call to __pskb_copy().
The skb enters create_stripped_skb_hsr() with ethernet header pushed in
linear buffer. The skb_pull(skb_in, HSR_HLEN) thus pulls 6 bytes of
ethernet header into the headroom, creating skb_in with a headroom of
size 8. The subsequent __pskb_copy() then creates an skb with headroom
of just 2 and skb->len of just 12, this is how it looks after the copy:
gdb) p skb->len
$10 = 12
(gdb) p skb->data
$11 = (unsigned char *) 0xffff888041e45382 "\252\252\252\252\252!\210\373",
(gdb) p skb->head
$12 = (unsigned char *) 0xffff888041e45380 ""
It seems create_stripped_skb_hsr() assumes that ETH header is pulled
in the headroom when it's entered, because it just pulls HSR header on
top. But that is not the case in our code-path and we end up with the
corrupted skb instead. I will call this BUG#2
*I got confused here because it seems that under no conditions can
create_stripped_skb_hsr() work well, the assumption it makes is not true
during the processing of hsr frames - since the skb_push() in
hsr_handle_frame to skb_pull in hsr_deliver_master(). I wonder whether I
missed something here.*
Next, the execution arrives in hsr_deliver_master(). It calls
skb_pull(ETH_HLEN), which just returns NULL - the SKB does not have
enough space for the pull (as it only has 12 bytes in total at this
point).
*The skb_pull() here further suggests that ethernet header is meant
to be pushed through the whole hsr processing and
create_stripped_skb_hsr() should pull it before doing the HSR header
pull.*
hsr_deliver_master() then puts the corrupted skb on the queue, it is
then picked up from there by bridge frame handling layer and finally
lands in br_dev_queue_push_xmit where it panics.

Currently ixgbe driver checks periodically in its watchdog subtask if
there is anything to be transmitted (considering both Tx and XDP rings)
under state of carrier not being 'ok'. Such event is interpreted as Tx
hang and therefore results in interface reset.
This is currently problematic for ndo_xdp_xmit() as it is allowed to
produce descriptors when interface is going through reset or its carrier
is turned off.
Furthermore, XDP rings should not really be objects of Tx hang
detection. This mechanism is rather a matter of ndo_tx_timeout() being
called from dev_watchdog against Tx rings exposed to networking stack.
Taking into account issues described above, let us have a two fold fix -
do not respect XDP rings in local ixgbe watchdog and do not produce Tx
descriptors in ndo_xdp_xmit callback when there is some problem with
carrier currently. For now, keep the Tx hang checks in clean Tx irq
routine, but adjust it to not execute for XDP rings.

Resolve the budget negative overflow which leads to returning true in
ixgbe_xmit_zc even when the budget of descs are thoroughly consumed.
Before this patch, when the budget is decreased to zero and finishes
sending the last allowed desc in ixgbe_xmit_zc, it will always turn back
and enter into the while() statement to see if it should keep processing
packets, but in the meantime it unexpectedly decreases the value again to
'unsigned int (0--)', namely, UINT_MAX. Finally, the ixgbe_xmit_zc returns
true, showing 'we complete cleaning the budget'. That also means
'clean_complete = true' in ixgbe_poll.
The true theory behind this is if that budget number of descs are consumed,
it implies that we might have more descs to be done. So we should return
false in ixgbe_xmit_zc to tell napi poll to find another chance to start
polling to handle the rest of descs. On the contrary, returning true here
means job done and we know we finish all the possible descs this time and
we don't intend to start a new napi poll.
It is apparently against our expectations. Please also see how
ixgbe_clean_tx_irq() handles the problem: it uses do..while() statement
to make sure the budget can be decreased to zero at most and the negative
overflow never happens.
The patch adds 'likely' because we rarely would not hit the loop condition
since the standard budget is 256.

Fixes on the Microchip's LAN865x driver
This patch series includes two bug fixes for the LAN865x Ethernet MAC-PHY
driver:
1. Fix missing transmit queue restart on device reopen
This patch addresses an issue where the transmit queue is not restarted
when the network interface is brought back up after being taken down
(e.g., via ip or ifconfig). As a result, packet transmission hangs
after the first down/up cycle. The fix ensures netif_start_queue() is
explicitly called in lan865x_net_open() to properly restart the queue
on every reopen.
2. Fix missing configuration in the Microchip LAN865x driver for silicon
revisions B0 and B1, as documented in Microchip Application Note AN1760
(Rev F, June 2024). These revisions require the MAC to be configured for
timestamping at the end of the Start of Frame Delimiter (SFD) and the
Timer Increment register to be set to 40 ns, corresponding to a 25 MHz
internal clock.
Both patches address issues introduced with the initial driver support and
are marked with the appropriate Fixes: tag.

Specifying the counter action is not enough, as it is used by multiple
counters that were allocated in a bulk. By omitting the offset, rules
will be associated with a different counter from the same bulk.
Subsequently, the CT subsystem checks the correct counter, assumes that
no traffic has triggered the rule, and ages out the rule. The end result
is intermittent offloading of long lived connections, as rules are aged
out then promptly re-added.
Fix this by specifying the correct offset along with the counter rule.

While moving the rules during rehash, CQ is not drained. The flush
and drain happens only when all the rules of a certain queue have been
moved. This behaviour can lead to accumulating large quantity of rules
that haven't got their completion yet, and eventually will fill up
the queue and will cause the rehash to fail.

Moving rules from matcher to matcher should not fail.
However, if it does fail due to various reasons, the error flow
should allow the kernel to continue functioning (albeit with broken
steering rules) instead of going into series of soft lock-ups or
some other problematic behaviour.
Similar to the simple rules, complex rules rehash logic suffers
from the same problems. This patch fixes the error flow for moving
complex rules:
- If new rule creation fails before it was even enqeued, do not
poll for completion
- If TIMEOUT happened while moving the rule, no point trying
to poll for completions for other rules. Something is broken,
completion won't come, just abort the rehash sequence.
- If some other completion with error received, don't give up.
Continue handling rest of the rules to minimize the damage.
- Make sure that the first error code that was received will
be actually returned to the caller instead of replacing it
with the generic error code.
All the aforementioned issues stem from the same bad error flow,
so no point fixing them one by one and leaving partially broken
code - fixing them in one patch.

steering rules) instead of going into series of soft lock-ups or
some other problematic behaviour.
This patch fixes the error flow for moving simple rules:
- If new rule creation fails before it was even enqeued, do not
poll for completion
- If TIMEOUT happened while moving the rule, no point trying
to poll for completions for other rules. Something is broken,
completion won't come, just abort the rehash sequence.
- If some other completion with error received, don't give up.
Continue handling rest of the rules to minimize the damage.
- Make sure that the first error code that was received will
be actually returned to the caller instead of replacing it
with the generic error code.
All the aforementioned issues stem from the same bad error flow,
so no point fixing them one by one and leaving partially broken
code - fixing them in one patch.

The clk_tx_i clock must be supplied to the MAC for successful
initialization. On TH1520 SoC, the clock is provided by an internal
divider configured through GMAC_PLLCLK_DIV register when using RGMII
interface. However, currently we don't setup the divider before
initialization of the MAC, resulting in DMA reset failures if the
bootloader/firmware doesn't enable the divider,

divisor, the divider must be disabled first and re-enabled later to make
sure the new divisor take effect.
The exact clock rate doesn't affect MAC's initialization according to my
test. It's set to the speed required by RGMII when the linkspeed is
1Gbps and could be reclocked later after link is up if necessary.

A crash can occur if an ethtool operation is invoked
after shutdown() is called.
shutdown() is invoked during system shutdown to stop DMA operations
without performing expensive deallocations. It is discouraged to
unregister the netdev in this path, so the device may still be visible
to userspace and kernel helpers.
In gve, shutdown() tears down most internal data structures. If an
ethtool operation is dispatched after shutdown(), it will dereference
freed or NULL pointers, leading to a kernel panic. While graceful
shutdown normally quiesces userspace before invoking the reboot
syscall, forced shutdowns (as observed on GCP VMs) can still trigger
this path.
Fix by calling netif_device_detach() in shutdown().
This marks the device as detached so the ethtool ioctl handler
will skip dispatching operations to the driver.

There was a problem when we received frames and the frames were
timestamped. The driver is configured to store the nanosecond part of
the timestmap in the ptp reserved bits and it would take the second part
by reading the LTC. The problem is that when reading the LTC we are in
atomic context and to read the second part will go over mdio bus which
might sleep, so we get an error.
The fix consists in actually put all the frames in a queue and start the
aux work and in that work to read the LTC and then calculate the full
received time.

When a user creates a dualpi2 qdisc it automatically sets a timer. This
timer will run constantly and update the qdisc's probability field.
The issue is that the timer acquires the qdisc root lock and runs in
hardirq. The qdisc root lock is also acquired in dev.c whenever a packet
arrives for this qdisc. Since the dualpi2 timer callback runs in hardirq,
it may interrupt the packet processing running in softirq. If that happens
and it runs on the same CPU, it will acquire the same lock and cause a
deadlock. The following splat shows up when running a kernel compiled with
lock debugging:

Firmwares are stopped
- emac_ndo_open()

In this path icssg_change_mode() doesn't get called and as a result the

ppp_fill_forward_path() has two race conditions:
1. The ppp->channels list can change between list_empty() and
list_first_entry(), as ppp_lock() is not held. If the only channel
is deleted in ppp_disconnect_channel(), list_first_entry() may
access an empty head or a freed entry, and trigger a panic.
2. pch->chan can be NULL. When ppp_unregister_channel() is called,
pch->chan is set to NULL before pch is removed from ppp->channels.
Fix these by using a lockless RCU approach:
- Use list_first_or_null_rcu() to safely test and access the first list
entry.
- Convert list modifications on ppp->channels to their RCU variants and
add synchronize_net() after removal.
- Check for a NULL pch->chan before dereferencing it.

When skb_ext_add(skb, SKB_EXT_MPTCP) fails in mptcp_incoming_options(),
we used to return true, letting the segment proceed through the TCP
receive path without a DSS mapping. Such segments can leave inconsistent
mapping state and trigger a mid-stream fallback to TCP, which in testing
collapsed (by artificially forcing failures in skb_ext_add) throughput
to zero.
Return false instead so the TCP input path drops the skb (see
tcp_data_queue() and step-7 processing). This is the safer choice
under memory pressure: it preserves MPTCP correctness and provides
backpressure to the sender.
Control packets remain unaffected: ACK updates and DATA_FIN handling
happen before attempting the extension allocation, and tcp_reset()
continues to ignore the return value.
With this change, MPTCP continues to work at high throughput if we
artificially inject failures into skb_ext_add.

When performing Generic Segmentation Offload (GSO) on an IPv6 packet that
contains extension headers, the kernel incorrectly requests checksum offload
if the egress device only advertises NETIF_F_IPV6_CSUM feature, which has
a strict contract: it supports checksum offload only for plain TCP or UDP
over IPv6 and explicitly does not support packets with extension headers.
The current GSO logic violates this contract by failing to disable the feature
for packets with extension headers, such as those used in GREoIPv6 tunnels.
This violation results in the device being asked to perform an operation
it cannot support, leading to a `skb_warn_bad_offload` warning and a collapse
of network throughput. While device TSO/USO is correctly bypassed in favor
of software GSO for these packets, the GSO stack must be explicitly told not
to request checksum offload.
Mask NETIF_F_IPV6_CSUM, NETIF_F_TSO6 and NETIF_F_GSO_UDP_L4
in gso_features_check if the IPv6 header contains extension headers to compute
checksum in software.
The exception is a BIG TCP extension, which, as stated in commit
68e068cabd ("net: reenable NETIF_F_IPV6_CSUM offload for BIG TCP packets"):
"The feature is only enabled on devices that support BIG TCP TSO.
The header is only present for PF_PACKET taps like tcpdump,
and not transmitted by physical devices."

The CI has hit a couple of cases of:
RUN global.data_steal ...
tls.c:2762:data_steal:Expected recv(cfd, buf2, sizeof(buf2), MSG_DONTWAIT) (20000) == -1 (-1)
data_steal: Test terminated by timeout
FAIL global.data_steal
Looks like the 2msec sleep is not long enough. Make the sleep longer,
and then instead of second sleep wait for the thieving process to exit.
That way we can be sure it called recv() before us.
While at it also avoid trying to steal more than a record, this seems
to be causing issues in manual testing as well.

While trying to fill a random RSS key, the size of the pointer
is being used rather than the actual size of the RSS key.
Fix by passing an appropriate value of the RSS key.
This issue was reported by static coverity analyser.

====================
mlxsw: spectrum: Forward packets with an IPv4 link-local source IP
By default, Spectrum devices do not forward IPv4 packets with a link-local
source IP (i.e., 169.254.0.0/16). This behavior does not align with the
kernel which does forward them. Fix the issue and add a selftest.
