Fei Liu reported a crash when doing netperf on a topo of macsec dev over veth: [ 448.919128] refcount_t: underflow; use-after-free. [ 449.090460] Call trace: [ 449.092895] refcount_sub_and_test+0xb4/0xc0 [ 449.097155] tcp_wfree+0x2c/0x150 [ 449.100460] ip_rcv+0x1d4/0x3a8 [ 449.103591] __netif_receive_skb_core+0x554/0xae0 [ 449.108282] __netif_receive_skb+0x28/0x78 [ 449.112366] netif_receive_skb_internal+0x54/0x100 [ 449.117144] napi_gro_complete+0x70/0xc0 [ 449.121054] napi_gro_flush+0x6c/0x90 [ 449.124703] napi_complete_done+0x50/0x130 [ 449.128788] gro_cell_poll+0x8c/0xa8 [ 449.132351] net_rx_action+0x16c/0x3f8 [ 449.136088] __do_softirq+0x128/0x320 The issue was caused by skb's true_size changed without its sk's sk_wmem_alloc increased in tcp/skb_gro_receive(). Later when the skb is being freed and the skb's truesize is subtracted from its sk's sk_wmem_alloc in tcp_wfree(), underflow occurs. macsec is calling gro_cells_receive() to receive a packet, which actually requires skb->sk to be NULL. However when macsec dev is over veth, it's possible the skb->sk is still set if the skb was not unshared or expanded from the peer veth. ip_rcv() is calling skb_orphan() to drop the skb's sk for tproxy, but it is too late for macsec's calling gro_cells_receive(). So fix it by dropping the skb's sk earlier on rx path of macsec. Fixes: 5491e7c6 ("macsec: enable GRO and RPS on macsec devices") Reported-by:

When removing a cbs instance when offloading is enabled, the crash below can be observed. The problem happens because that when offloading is enabled, the cbs instance is not added to the list. Also, the current code doesn't handle correctly the case when offload is disabled without removing the qdisc: if the link speed changes the credit calculations will be wrong. When we create the cbs instance with offloading enabled, it's not added to the notification list, when later we disable offloading, it's not in the list, so link speed changes will not affect it. The solution for both issues is the same, add the cbs instance being created unconditionally to the global list, even if the link state notification isn't useful "right now".

The second ensures that no more than one thread runs in reset at a time. v2: - Separate change param reset from do_reset() - Return IBMVNIC_OPEN_FAILED if __ibmvnic_open fails - Remove setting wait_for_reset to false from __ibmvnic_reset(), this is done in wait_for_reset() - Move the check for force_reset_recovery from patch 1 to patch 2 v3: - Restore reset’s successful return in open failure case v4: - Change resetting flag access to atomic ==================== Signed-off-by: -

Commit a5681e20 ("net/ibmnvic: Fix deadlock problem in reset") made the change to hold the RTNL lock during a reset to avoid deadlock but linkwatch_event is fired during the reset and needs the RTNL lock. That keeps linkwatch_event process from proceeding until the reset is complete. The reset process cannot tolerate the linkwatch_event processing after reset completes, so release the RTNL lock during the process to allow a chance for linkwatch_event to run during reset. This does not guarantee that the linkwatch_event will be processed as soon as link state changes, but is an improvement over the current code where linkwatch_event processing is always delayed, which prevents transmissions on the device from being deactivated leading transmit watchdog timer to time-out. Release the RTNL lock before link state change and re-acquire after the link state change to allow linkwatch_event to grab the RTNL lock and run during the reset.

In mlx5 parse_tunnel_attr() function dispatch on encap IP address type is performed by directly checking flow_rule_match_key() on FLOW_DISSECTOR_KEY_ENC_IPV4_ADDRS, and then on FLOW_DISSECTOR_KEY_ENC_IPV6_ADDRS. However, since those are stored in union, first check is always true if any type of encap address is set, which leads to IPv6 tunnel encap address being parsed as IPv4 by mlx5. Determine correct IP address type by checking control key first and if it set, take address type from match.key->addr_type.

Before this patch, when adding multiple ethtool steering rules with identical classification, the driver used to append the new destination to the already existing hw rule, which caused the hw to forward the traffic to all destinations (rx queues). Here we avoid this by setting the "no append" mlx5 fs core flag when adding a new ethtool rule. Fixes: 6dc6071c ("net/mlx5e: Add ethtool flow steering support") Signed-off-by:

Putting a struct stmmac_rss object on the stack is a bad idea, as it exceeds the warning limit for a stack frame on 32-bit architectures: drivers/net/ethernet/stmicro/stmmac/stmmac_selftests.c:1221:12: error: stack frame size of 1208 bytes in function '__stmmac_test_l3filt' [-Werror,-Wframe-larger-than=] drivers/net/ethernet/stmicro/stmmac/stmmac_selftests.c:1338:12: error: stack frame size of 1208 bytes in function '__stmmac_test_l4filt' [-Werror,-Wframe-larger-than=] As the object is the trivial empty case, change the called function to accept a NULL pointer to mean the same thing and remove the large variable in the two callers.
