For the reasons explained in commit ce105008 ("tcp/dccp: fix ireq->pktopts race"), we need to make sure we do not access req->saved_syn unless we own the request sock. This fixes races for listeners using TCP_SAVE_SYN option. Fixes: e994b2f0 ("tcp: do not lock listener to process SYN packets") Fixes: 079096f1 ("tcp/dccp: install syn_recv requests into ehash table") Signed-off-by:

Vivien Didelot authored
The DSA documentation specifies that each port must be capable of forwarding frames to the CPU port. The last changes on bridging support for the mv88e6xxx driver broke this requirement for non-bridged ports. So as for the bridged ports, reserve a few VLANs (4000+) in the switch to isolate ports that have not been bridged yet. By default, a port will be isolated with the CPU and DSA ports. When the port joins a bridge, it will leave its reserved port. When it is removed from a bridge, it will join its reserved VLAN again. Fixes: 5fe7f680 ("net: dsa: mv88e6xxx: fix hardware bridging") Reported-by:

VXLAN may be a loadable module, and this driver cannot be built-in in that case, or we get a link error: drivers/built-in.o: In function `__bnxt_open_nic': drivers/net/ethernet/broadcom/bnxt/bnxt.c:4581: undefined reference to `vxlan_get_rx_port' This adds a Kconfig dependency that ensures that either VXLAN is disabled (which the driver handles correctly), or we depend on VXLAN itself and disallow built-in compilation when VXLAN is a module.

When a listen socket enqueues a connection for userspace to accept(), the sk->sk_data_ready() callback should be invoked. In-kernel socket users rely on this callback to detect when incoming connections are available. Currently the sk->sk_state_change() callback is invoked by vmci_transport.c. This happens to work for userspace applications since sk->sk_state_change = sock_def_wakeup() and sk->sk_data_ready = sock_def_readable() both wake up the accept() waiter. In-kernel socket users, on the other hand, fail to detect incoming connections. Signed-off-by:

With moving netdev_sync_lower_features() after the .ndo_set_features calls, I neglected to verify that devices added *after* a flag had been disabled on an upper device were properly added with that flag disabled as well. This currently happens, because we exit __netdev_update_features() when we see dev->features == features for the upper dev. We can retain the optimization of leaving without calling .ndo_set_features with a bit of tweaking and a goto here.

Sasha reported the following lockdep warning: Possible unsafe locking scenario: CPU0 CPU1 ---- ---- lock(sk_lock-AF_INET); lock(rtnl_mutex); lock(sk_lock-AF_INET); lock(rtnl_mutex); This is due to that for IP_MSFILTER and MCAST_MSFILTER, we take rtnl lock before the socket lock in setsockopt() path, but take the socket lock before rtnl lock in getsockopt() path. All the rest optnames are setsockopt()-only. Fix this by aligning the getsockopt() path with the setsockopt() path, so that all mcast socket path would be locked in the same order.
