If the socket is closed or is being released, some resources used by virtio_transport_space_update() such as 'vsk->trans' may be released. To avoid a use after free bug we should only update the available credit when we are sure the socket is still open and we have the lock held.

The sctp transport seq_file iterators take a reference to the transport in the ->start and ->next functions and releases the reference in the ->show function. The preferred handling for such resources is to release them in the subsequent ->next or ->stop function call. Since Commit 1f4aace6 ("fs/seq_file.c: simplify seq_file iteration code and interface") there is no guarantee that ->show will be called after ->next, so this function can now leak references. So move the sctp_transport_put() call to ->next and ->stop. Fixes: 1f4aace6 ("fs/seq_file.c: simplify seq_file iteration code and interface") Reported-by:

A possible locking issue in vsock_connect_timeout() was recognized by Eric Dumazet which might cause a null pointer dereference in vsock_transport_cancel_pkt(). This patch assures that vsock_transport_cancel_pkt() will be called within the lock, so a race condition won't occur which could result in vsk->transport to be set to NULL.

In vsock_stream_connect(), a thread will enter schedule_timeout(). While being scheduled out, another thread can enter vsock_stream_connect() as well and set vsk->transport to NULL. In case a signal was sent, the first thread can leave schedule_timeout() and vsock_transport_cancel_pkt() will be called right after. Inside vsock_transport_cancel_pkt(), a null dereference will happen on transport->cancel_pkt. Fixes: c0cfa2d8 ("vsock: add multi-transports support") Signed-off-by:

Normally we clear the failover_pending flag when processing the reset. But if we are unable to schedule a failover reset we must clear the flag ourselves. We could fail to schedule the reset if we are in PROBING state (eg: when booting via kexec) or because we could not allocate memory. Thanks to Cris Forno for helping isolate the problem and for testing. Fixes: 1d850493 ("powerpc/vnic: Extend "failover pending" window") Signed-off-by:

When disable CBS, mode_to_use parameter is not updated even the operation mode of Tx Queue is changed to Data Centre Bridging (DCB). Therefore, when tc_setup_cbs() function is called to re-enable CBS, the operation mode of Tx Queue remains at DCB, which causing CBS fails to work. This patch updates the value of mode_to_use parameter to MTL_QUEUE_DCB after operation mode of Tx Queue is changed to DCB in stmmac_dma_qmode() callback function.

Camelia Groza says: ==================== dpaa_eth: A050385 erratum workaround fixes under XDP This series addresses issue with the current workaround for the A050385 erratum in XDP scenarios. The first patch makes sure the xdp_frame structure stored at the start of new buffers isn't overwritten. The second patch decreases the required data alignment value, thus preventing unnecessary realignments. The third patch moves the data in place to align it, instead of allocating a new buffer for each frame that breaks the alignment rules, thus bringing an up to 40% performance increase. With this change, the impact of the erratum workaround is reduced in many cases to a single digit decrease, and to lower double digits in single flow scenarios.

The 256 byte data alignment is required for preventing DMA transaction splits when crossing 4K page boundaries. Since XDP deals only with page sized buffers or less, this restriction isn't needed. Instead, the data only needs to be aligned to 64 bytes to prevent DMA transaction splits. These lessened restrictions can increase performance by widening the pool of permitted data alignments and preventing unnecessary realignments.

When the erratum workaround is triggered, the newly created xdp_frame structure is stored at the start of the newly allocated buffer. Avoid the structure from being overwritten by explicitly reserving enough space in the buffer for storing it. Account for the fact that the structure's size might increase in time by aligning the headroom to DPAA_FD_DATA_ALIGNMENT bytes, thus guaranteeing the data's alignment.

Commit c8079432 ("net: Fix packet reordering caused by GRO and listified RX cooperation") had the unfortunate effect of adding latencies in common workloads. Before the patch, GRO packets were immediately passed to upper stacks. After the patch, we can accumulate quite a lot of GRO packets (depdending on NAPI budget). My fix is counting in napi->rx_count number of segments instead of number of logical packets. Fixes: c8079432 ("net: Fix packet reordering caused by GRO and listified RX cooperation") Signed-off-by:

That comes as a bit of a surprise, since the driver does not do initialization of the RFS memory. Also, the initialization of the Receive Side Scaling is done only partially. Even though the entire ENETC IP has a single shared flow steering memory, the flow steering service should returns matches only for TCAM entries that are within the range of the Station Interface that is doing the search. Therefore, it should be sufficient for a Station Interface to initialize all of its own entries in order to avoid any ECC errors, and only the Station Interfaces in use should need initialization. There are Physical Station Interfaces associated with PCIe PFs and Virtual Station Interfaces associated with PCIe VFs. We let the PF driver initialize the entire port's memory, which includes the RFS entries which are going to be used by the VF. Reported-by:

When iteratively computing a checksum with csum_block_add, track the offset "pos" to correctly rotate in csum_block_add when offset is odd. The open coded implementation of skb_copy_and_csum_datagram did this. With the switch to __skb_datagram_iter calling csum_and_copy_to_iter, pos was reinitialized to 0 on each call.

At the end of rxrpc_release_call(), rxrpc_cleanup_ring() is called to clear the Rx/Tx skbuff ring, but this doesn't lock the ring whilst it's accessing it. Unfortunately, rxrpc_resend() might be trying to retransmit a packet concurrently with this - and whilst it does lock the ring, this isn't protection against rxrpc_cleanup_call(). Fix this by removing the call to rxrpc_cleanup_ring() from rxrpc_release_call(). rxrpc_cleanup_ring() will be called again anyway from rxrpc_cleanup_call(). The earlier call is just an optimisation to recycle skbuffs more quickly. Alternative solutions include rxrpc_release_call() could try to cancel the work item or wait for it to complete or rxrpc_cleanup_ring() could lock when accessing the ring (which would require a bh lock). This can produce a report like the following: BUG: KASAN: use-after-free in rxrpc_send_data_packet+0x19b4/0x1e70 net/rxrpc/output.c:372 Read of size 4 at addr ffff888011606e04 by task kworker/0:0/5 ...

This leads to an error in the case that GRO is used and packets are split up in GSO. The tcp or udp checksum of all packets is incorrect. The error is probably masked due to the fact the most network driver implement tcp/udp checksum offloading. It also only happens when GRO is applied and not on single packets.

sup_multicast_addr is passed to ether_addr_equal for address comparison which casts the address inputs to u16 leading to an unaligned access. Aligning the sup_multicast_addr to u16 boundary fixes the issue. Signed-off-by:

Saeed Mahameed says: ==================== mlx5 fixes 2021-02-01 Please note the first patch in this series ("Fix function calculation for page trees") is fixing a regression due to previous fix in net which you didn't include in your previous rc pr. So I hope this series will make it into your next rc pr, so mlx5 won't be broken in the next rc. * tag 'mlx5-fixes-2021-02-01' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5e: Release skb in case of failure in tc update skb net/mlx5e: Update max_opened_tc also when channels are closed net/mlx5: Fix leak upon failure of rule creation net/mlx5: Fix function calculation for page trees ==================== Link: https://lore.kernel.org/r/20210202070703.617251-1-saeed@kernel.orgSigned-off-by: -

Alex Elder says: ==================== net: ipa: a few bug fixes This series fixes four minor bugs. The first two are things that sparse points out. All four are very simple and each patch should explain itself pretty well. ==================== Link: https://lore.kernel.org/r/20210201232609.3524451-1-elder@linaro.orgSigned-off-by:

When extracting the destination endpoint ID from the status in ipa_endpoint_status_skip(), u32_get_bits() is used. This happens to work, but it's wrong: the structure field is only 8 bits wide instead of 32. Fix this by using u8_get_bits() to get the destination endpoint ID. Signed-off-by:
