2010-05-11netfilter: xtables: deconstify struct xt_action_param for matchesJan Engelhardt1-1/+1
In future, layer-3 matches will be an xt module of their own, and need to set the fragoff and thoff fields. Adding more pointers would needlessy increase memory requirements (esp. so for 64-bit, where pointers are wider). Signed-off-by: Jan Engelhardt <jengelh@medozas.de>

2009-08-10netfilter: xtables: remove xt_owner v0Jan Engelhardt1-118/+12
Superseded by xt_owner v1 (v2.6.24-2388-g0265ab4). Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
2008-11-14CRED: Use creds in file structsDavid Howells1-8/+8
Attach creds to file structs and discard f_uid/f_gid. file_operations::open() methods (such as hppfs_open()) should use file->f_cred rather than current_cred(). At the moment file->f_cred will be current_cred() at this point.

2008-10-08netfilter: xtables: use NFPROTO_UNSPEC in more extensionsJan Engelhardt1-11/+1
Lots of extensions are completely family-independent, so squash some code. Signed-off-by: Jan Engelhardt <jengelh@medozas.de> Signed-off-by: Patrick McHardy <kaber@trash.net>
2008-10-08netfilter: xtables: move extension arguments into compound structure (2/6)Jan Engelhardt1-10/+4
This patch does this for match extensions' checkentry functions. Signed-off-by: Jan Engelhardt <jengelh@medozas.de> Signed-off-by: Patrick McHardy <kaber@trash.net>
2008-10-08netfilter: xtables: move extension arguments into compound structure (1/6)Jan Engelhardt1-15/+6
The function signatures for Xtables extensions have grown over time. It involves a lot of typing/replication, and also a bit of stack space even if they are not used. Realize an NFWS2008 idea and pack them into structs. The skb remains outside of the struct so gcc can continue to apply its optimizations. This patch does this for match extensions' match functions. A few ambiguities have also been addressed. The "offset" parameter for example has been renamed to "fragoff" (there are so many different offsets already) and "protoff" to "thoff" (there is more than just one protocol here, so clarify).

2008-01-31[NETFILTER]: xt_owner: allow matching UID/GID rangesJan Engelhardt1-6/+8
Add support for ranges to the new revision. This doesn't affect compatibility since the new revision was not released yet. Signed-off-by: Jan Engelhardt <jengelh@computergmbh.de> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-01-28[NETFILTER]: Update modules' descriptionsJan Engelhardt1-1/+1
Updates the MODULE_DESCRIPTION() tags for all Netfilter modules, actually describing what the module does and not just "netfilter XYZ target".

2008-01-28[NETFILTER]: merge ipt_owner/ip6t_owner in xt_ownerJan Engelhardt1-0/+211
xt_owner merges ipt_owner and ip6t_owner, and adds a flag to match on socket (non-)existence. Signed-off-by: Jan Engelhardt <jengelh@computergmbh.de> Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
