Description:
bugreport from Paolo Lucente <[EMAIL PROTECTED]>:
the mpls stack processing is broken:
for example "mpls 10000 && mpls 20000" does produce
reading from file ppp.pcap, link-type PPP (PPP)
(000) ldh [2]
(001) jeq #0x00000281 jt 2 jf 11
(002) ld [4]
(003) and #0xfffff000
(004) jeq #0x02710000 jt 5 jf 11
(005) ldh [6]
(006) jeq #0x00000281 jt 7 jf 11
(007) ld [8]
(008) and #0xfffff000
(009) jeq #0x04e20000 jt 10 jf 11
(010) ret #1514
(011) ret #0
the extra match for 0x281 at instruction #6 is broken and
a copy&paste artifact from the vlan code generator, which
in contrast does require the VLAN tag 0x8100 at every instance
inside a VLAN stack;
correct code should be:
(000) ldh [2]
(001) jeq #0x281 jt 2 jf 9
(002) ld [4]
(003) and #0xfffff000
(004) jeq #0x2710000 jt 5 jf 9
(005) ld [8]
(006) and #0xfffff000
(007) jeq #0x4e20000 jt 8 jf 9
(008) ret #1514
(009) ret #0
