[ng_socket] Don't take the SOCKBUF_LOCK() twice in the RX data path.

This is just a minor optimization, but it's sensitive. This gives an improvement of 30-50 kpps. Reviewed by: kp, markj, glebius, lutz_donnerhacke.de Approved by: vmaffione (mentor) Sponsored by: vstack.com Differential Revision: https://reviews.freebsd.org/D27382

netgraph: macfilter: small fixes

2020-12-09T15:28:56Z

Two issues: - The DEBUG macro defined is in direct conflict with the DEBUG kernel option, which broke the -LINT build[0] - Building with NG_MACFILTER_DEBUG did not compile on LP64 systems due to using %d for sizeof(). Reported by: Jenkins[0]

ng_l2tp: Fix callout synchronization in the rexmit timeout handler

2020-09-25T18:55:50Z

A received control packet may cause the transmit queue to be flushed, in which case ng_l2tp_seq_recv_nr() cancels the transmit timeout handler. The handler checks to see if it was cancelled before doing anything, but did so before acquiring the node lock, so a small race window could cause ng_l2tp_seq_rack_timeout() to attempt to flush an empty queue, ultimately causing a null pointer dereference.

ng_ether: Enter NET_EPOCH where required

2020-09-02T11:49:22Z

We must enter NET_EPOCH before calling ether_output_frame(). Several of the functions it calls (pfil_run_hooks, if_transmit) expect to be running in the NET_EPOCH. While here remove an unneeded EPOCH entry (which wasn't wide enough to cover BRIDGE_INPUT).
