Subject: [bpf PATCH v2 0/6] sockmap fixes
Date: Thu, 12 Nov 2020 15:26:19 -0800 [thread overview]
Message-ID: <160522352433.135009.15329422887113794062.stgit@john-XPS-13-9370> (raw)
This includes fixes for sockmap found after I started running skmsg and
verdict programs on systems that I use daily. To date with attached
series I've been running for multiple weeks without seeing any issues
on systems doing calls, mail, movies, etc.
Also I started running packetdrill and after this series last remaining
fix needed is to handle MSG_EOR correctly. This will come as a follow
up to this, but because we use sendpage to pass pages into TCP stack
we need to enable TCP side some.
v2:
- Added patch3 to use truesize in sk_rmem_schedule (Daniel)
- cleaned up some small nits... goto and extra set of brackets (Daniel)
