src/sys/netinet6: in6_l2tp.c
Log Message:
Several fixes in L2TP:
* l2tp_input(): use m_copydata, and ensure there is enough space in the
chain. Otherwise overflow.
* l2tp_tcpmss_clamp(): ensure there is enough space in the chain.
* in_l2tp_output(): don't check 'sc' against NULL, it can't be NULL.
* in_l2tp_input(): no need to call m_pullup since we use m_copydata.
Just check the space in the chain.
* in_l2tp_input(): if there is a cookie, make sure the chain has enough
space.
* in6_l2tp_input(): same changes as in_l2tp_input().
