Subject: [PATCH bpf 0/2] sockmap fix for KASAN_VMALLOC and af_unix
Date: Mon, 16 Oct 2023 12:08:17 -0700	[thread overview]
Message-ID: <20231016190819.81307-1-john.fastabend@gmail.com> (raw)

The af_unix tests in sockmap_listen causes a splat from KASAN_VMALLOC.
Fix it here and include an extra test to catch case where both pairs
of the af_unix socket are included in a BPF sockmap.

John Fastabend (2):
  bpf: sockmap, af_unix sockets need to hold ref for pair sock
  bpf: sockmap, add af_unix test with both sockets in map
