kernel/include/trace/events/sock.h, branch linux-3.11.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-3.11.y2011-06-21T23:06:10Zcore: add tracepoints for queueing skb to rcvbuf2011-06-21T23:06:10ZSatoru Moriyasatoru.moriya@hds.com2011-06-17T12:00:03Zurn:sha1:3847ce32aea9fdf56022de132000e8cf139042eb
This patch adds 2 tracepoints to get a status of a socket receive queue
and related parameter.
One tracepoint is added to sock_queue_rcv_skb. It records rcvbuf size
and its usage. The other tracepoint is added to __sk_mem_schedule and
it records limitations of memory for sockets and current usage.
By using these tracepoints we're able to know detailed reason why kernel
drop the packet.
