Subject: [PATCH bpf 0/3] Devmap fixes around memory and RCU
Date: Fri, 14 Jun 2019 17:20:12 +0900 [thread overview]
Message-ID: <20190614082015.23336-1-toshiaki.makita1@gmail.com> (raw)
Patch1: Jesper showed concerns around devmap free and flush race when
reviewing my XDP bulk TX patch set, and I think indeed there is a
race. Patch1 fix it.
Patch2: While reviewing dev_map_free I found bulk queue was not freed.
Patch2 fix it.
Patch3: Some days ago David Ahern reported suspicous RCU usage in
virtnet_xdp_xmit(), but it seems no one posted an official fix
patch. So I arraged the fix.
Signed-off-by: Toshiaki Makita <toshiaki.makita1@gmail.com>
Toshiaki Makita (3):
devmap: Fix premature entry free on destroying map
devmap: Add missing bulk queue free
devmap: Add missing RCU read lock on flush
