This series proposes a new helper for the BPF API which allows BPF programs to
perform lookups for sockets in a network namespace. This would allow programs
to determine early on in processing whether the stack is expecting to receive
the packet, and perform some action (eg drop, forward somewhere)
This patch adds new BPF helper functions, bpf_sk_lookup_tcp() and
bpf_sk_lookup_udp() which allows BPF programs to find out if there is a
socket listening on this host, and returns a socket pointer which the
BPF program can then access to determine, for instance, whether to
forward or drop traffic.
Allow helper functions to acquire a reference and return it into a
register. Specific pointer types such as the PTR_TO_SOCKET will
implicitly represent such a reference. The verifier must ensure that
these references are released exactly once in each path through the
program.
To achieve this, this
Teach the verifier a little bit about a new type of pointer, a
PTR_TO_SOCKET. This pointer type is accessed from BPF through the

llc_sap_close() is called by llc_sap_put() which
could be called in BH context in llc_rcv(). We can't
block in BH.
There is no reason to block it here, kfree_rcu() should
be sufficient.

The bridge mdb show is broken on current iproute2. e.g.

After fix:

Hi!
Two fixes for flower matching and tunnel encap. Pieter fixes
VLAN matching if the entire VLAN id is masked out and match
is only performed on the PCP field. Louis adds validation of
tunnel flags for encap, most importantly we should not offload
actions on IPv6 tunnels if it's not supported.
