There's a race between the retransmission code and the received ACK parser. The problem is that the retransmission loop has to drop the lock under which it is iterating through the transmission buffer in order to transmit a packet, but whilst the lock is dropped, the ACK parser can crank the Tx window round and discard the packets from the buffer. The retransmission code then updated the annotations for the wrong packet and a later retransmission thought it had to retransmit a packet that wasn't there, leading to a NULL pointer dereference. Fix this by: (1) Moving the annotation change to before we drop the lock prior to transmission. This means we can't vary the annotation depending on the outcome of the transmission, but that's fine - we'll retransmit again later if it failed now. (2) Skipping the packet if the skb pointer is NULL. The following oops was seen: BUG: kernel NULL pointer dereference, address: 000000000000002d Workqueue: krxrpcd rxrpc_process_call RIP: 0010:rxrpc_get_skb+0x14/0x8a ...

When a bearer is enabled, we create a 'tipc_discoverer' object to store the bearer related data along with a timer and a preformatted discovery message buffer for later probing... However, this is only carried after the bearer was set 'up', that left a race condition resulting in kernel panic. It occurs when a discovery message from a peer node is received and processed in bottom half (since the bearer is 'up' already) just before the discoverer object is created but is now accessed in order to update the preformatted buffer (with a new trial address, ...) so leads to the NULL pointer dereference. We solve the problem by simply moving the bearer 'up' setting to later, so make sure everything is ready prior to any message receiving. Acked-by:

syzbot found the following issue: WARNING: CPU: 0 PID: 6808 at include/linux/thread_info.h:150 check_copy_size include/linux/thread_info.h:150 [inline] WARNING: CPU: 0 PID: 6808 at include/linux/thread_info.h:150 copy_from_iter include/linux/uio.h:144 [inline] WARNING: CPU: 0 PID: 6808 at include/linux/thread_info.h:150 tipc_msg_append+0x49a/0x5e0 net/tipc/msg.c:242 Kernel panic - not syncing: panic_on_warn set ... This happens after commit 5e9eeccc ("tipc: fix NULL pointer dereference in streaming") that tried to build at least one buffer even when the message data length is zero... However, it now exposes another bug that the 'mss' can be zero and the 'cpy' will be negative, thus the above kernel WARNING will appear! The zero value of 'mss' is never expected because it means Nagle is not enabled for the socket (actually the socket type was 'SOCK_SEQPACKET'), so the function 'tipc_msg_append()' must not be called at all. But that was in this particular case since the message data length was zero, and the 'send <= maxnagle' check became true. We resolve the issue by explicitly checking if Nagle is enabled for the socket, i.e. 'maxnagle != 0' before calling the 'tipc_msg_append()'. We also reinforce the function to against such a negative values if any. Reported-by: syzbot+75139a7d2605236b0b7f@syzkaller.appspotmail.com Fixes: c0bceb97 ("tipc: add smart nagle feature") Acked-by:

The netif_running() test looks at __LINK_STATE_START which gets set before ndo_open() is called, there is a window of time between that and when the queues are actually ready to be run. If ionic_check_link_status() notices that the link is up very soon after netif_running() becomes true, it might try to run the queues before they are ready, causing all manner of potential issues. Since the netdev->flags IFF_UP isn't set until after ndo_open() returns, we can wait for that before we allow ionic_check_link_status() to start the queues. On the way back to close, __LINK_STATE_START is cleared before calling ndo_stop(), and IFF_UP is cleared after. Both of these need to be true in order to safely stop the queues from ionic_check_link_status(). Fixes: 49d3b493 ("ionic: disable the queues on link down") Signed-off-by:

The dynamic key update for addr_list_lock still causes troubles, for example the following race condition still exists: CPU 0: CPU 1: (RCU read lock) (RTNL lock) dev_mc_seq_show() netdev_update_lockdep_key() -> lockdep_unregister_key() -> netif_addr_lock_bh() because lockdep doesn't provide an API to update it atomically. Therefore, we have to move it back to static keys and use subclass for nest locking like before. In commit 1a33e10e ("net: partially revert dynamic lockdep key changes"), I already reverted most parts of commit ab92d68f ("net: core: add generic lockdep keys"). This patch reverts the rest and also part of commit f3b0a18b ("net: remove unnecessary variables and callback"). After this patch, addr_list_lock changes back to using static keys and subclasses to satisfy lockdep. Thanks to dev->lower_level, we do not have to change back to ->ndo_get_lock_subclass(). And hopefully this reduces some syzbot lockdep noises too.

Use vm_insert_pages() for tcp receive zerocopy. Spin lock cycles (as reported by perf) drop from a couple of percentage points to a fraction of a percent. This results in a roughly 6% increase in efficiency, measured roughly as zerocopy receive count divided by CPU utilization. The intention of this patchset is to reduce atomic ops for tcp zerocopy receives, which normally hits the same spinlock multiple times consecutively.

This selftest tests for cases where sendfile's 'count' parameter is provided with a size greater than the intended file size. Motivation: When sendfile is provided with 'count' parameter value that is greater than the size of the file, kTLS example fails to send the file correctly. Last chunk of the file is not sent, and the data integrity is compromised. The reason is that the last chunk has MSG_MORE flag set because of which it gets added to pending records, but is not pushed. Note that if user space were to send SSL_shutdown control message, pending records would get flushed and the issue would not happen. So a shutdown control message following sendfile can mask the issue. Signed-off-by:

While trying to use the lantiq_gswip driver on one of my boards I made a mistake when specifying the phy-mode (because the out-of-tree driver wants phy-mode "gmii" or "mii" for the internal PHYs). In this case the following error is printed multiple times: Unsupported interface: 3 While it gives at least a hint at what may be wrong it is not very user friendly. Print the human readable phy-mode and also which port is configured incorrectly (this hardware supports ports 0..6) to improve the cases where someone made a mistake.

The driver registers three different types of thermal zones: For the ASIC itself, for port modules and for gearboxes. Currently, all three types use the same get_trend() callback which does not work correctly for the ASIC thermal zone. The callback assumes that the device data is of type 'struct mlxsw_thermal_module', whereas for the ASIC thermal zone 'struct mlxsw_thermal' is passed as device data. Fix this by using one get_trend() callback for the ASIC thermal zone and another for the other two types. Fixes: 6f73862f ("mlxsw: core: Add the hottest thermal zone detection") Signed-off-by:
