[Bridge] Bridge and PACKET-socket
Ahoy,
I've encountered some confusing semantics with using PACKET(7) sockets
on bridge-enslaved interfaces. Specifically, if my socket accepts all
types of frame (bind() to ETH_P_ALL) then it gets all packets; but if
it accepts any specific type (e.g. ETH_P_IP), then it receives no
packets at all.
That is how it's coded in net/core/dev.c's netif_receive_skb(). First
ETH_P_ALL handlers are called, then the bridge, and then -- only if
the bridge declines the packet -- t...

tcng version 8w
...- I''ve added fields for skb meta-data (meta_protocol, etc.)
- if USE_META_PROTOCOL is #defined (tcc -D... or tcsim -Xc,-D...),
ip_hdr and ip6_hdr check the protocol number
- if_u32 generates distinct classifier branches for each protocol
- f_fw, f_tcindex, and f_u32 now default to ETH_P_ALL instead of
ETH_P_IP
The latter change affects how u32 classification works !
tests/protu32 illustrates how protocol-aware classification
is used.
What''s missing:
- C and tcc-ext-match need to support meta_protocol too
- if_u32 does a few ugly things, and can also generate redundan...
