sys/netmpls : Tag: OPENBSD_6_2 mpls_input.c
Log message:
The per-interface mpls flag should also also be tested on input
before proceeding, as described in ifconfig documentation.
mpls_shim_pop() can return NULL. Check it else we end up dereferencing
NULL.
The adjttl functions use m_pullup(). In some cases m_pullup() can
return a new mbuf chain and this chain needs to be returned to the
caller else a use after free may happen.
Use m_freem() in error case.
Pullup the mbuf before accessing the version field in the IP header.
Fix the pullup length of the shim header in mpls_do_error().
