2006-09-28[TCP]: struct tcp_sack_block annotationsAl Viro1-1/+1
Some of the instances of tcp_sack_block are host-endian, some - net-endian. Define struct tcp_sack_block_wire identical to struct tcp_sack_block with u32 replaced with __be32; annotate uses of tcp_sack_block replacing net-endian ones with tcp_sack_block_wire. Change is obviously safe since for cc(1) __be32 is typedefed to u32. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>

2006-09-22[NETFILTER]: PPTP conntrack: fix another GRE keymap leakPatrick McHardy2-10/+7
When the master PPTP connection times out while still having unfullfilled expectations (and a GRE keymap entry) associated with it, the keymap entry is not destroyed. Add a destroy callback to struct ip_conntrack_helper and use it to destroy PPTP siblings when the master is destroyed. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-09-22[NETFILTER]: PPTP conntrack: fix GRE keymap leakPatrick McHardy1-0/+1
When destroying the GRE expectations without having seen the GRE connection the keymap entry is not freed, leading to a memory leak and, in case of a following call within the same session, failure during expectation setup.

2006-09-22[NETFILTER]: PPTP conntrack: fix PPTP_IN_CALL message typesPatrick McHardy2-6/+8
Fix incorrectly used message types and call IDs: - PPTP_IN_CALL_REQUEST (PAC->PNS) contains a PptpInCallRequest (icreq) message and the PAC call ID - PPTP_IN_CALL_REPLY (PNS->PAC) contains a PptpInCallReply (icack) message and the PNS call ID Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.
