ip: generate unique IP identificator if local fragmentation is allowed

2013-09-19T18:11:15+00:00

If local fragmentation is allowed, then ip_select_ident() and ip_select_ident_more() need to generate unique IDs to ensure correct defragmentation on the peer. For example, if IPsec (tunnel mode) has to encrypt large skbs that have local_df bit set, then all IP fragments that belonged to different ESP datagrams would have used the same identificator. If one of these IP fragments would get lost or reordered, then peer could possibly stitch together wrong IP fragments that did not belong to the same datagram. This would lead to a packet loss or data corruption. Signed-off-by: Ansis Atteka Signed-off-by: David S. Miller

pptp: fix byte order warnings

2013-08-13T22:10:22+00:00

Pptp driver has lots of byte order warnings from sparse. This was because the on-the-wire header is in network byte order (obviously) but the definition did not reflect that. Also, the address structure to user space actually put the call id in host order. Rather than break ABI compatibility, just acknowledge the existing design.

pptp: fix sparse pointer warning

pptp: lookup route with the proper net namespace

2012-08-08T22:57:10+00:00

pptp always use init_net as the net namespace to lookup route, this will cause route lookup failed in container. because we already set the correct net namespace to struct sock in pptp_create,so fix this by using sock_net(sk) to replace &init_net.

ppp: Move ioctl definitions from if_ppp.h to new ppp-ioctl.h

2012-03-05T01:41:38+00:00

This moves the definitions of the ioctls, constants and structures relating to the ppp_generic interface to userspace out from if_ppp.h to a new file, ppp-ioctl.h. The new file has my copyright since I designed and implemented the ppp_generic interface in the late 1990s. None of the contents of this file comes from the original if_ppp.h published by Carnegie Mellon University. Of the remainder of if_ppp.h, only the PPP_MTU definition was being used, and this replaces the uses of it with PPP_MRU (which is identical). Therefore, this replaces the entire file with the single line #include which clearly doesn't contain any CMU code. Thus I have removed the CMU copyright notice with its problematic advertising clause, and in fact since it's only one trivial line I have not added any other copyright notice.

drivers/net: Remove unnecessary k.alloc/v.alloc OOM messages

alloc failures use dump_stack so emitting an additional out-of-memory message is an unnecessary duplication. Remove the allocation failure messages. Signed-off-by: Joe Perches Signed-off-by: David S. Miller

pptp: Accept packet with seq zero

Initialize the PPTP "seq received" value to 0xffffffff, so we don't ignore packets with seq zero. Signed-off-by: Bradley Peterson Signed-off-by: David S. Miller
