netfilter: allow to turn off xtables compat layer The compat layer needs to parse untrusted input (the ruleset) to translate it to a 64bit compatible format. We had a number of bugs in this department in the past, so allow users to turn this feature off. Add CONFIG_NETFILTER_XTABLES_COMPAT kconfig knob and make it default to y to keep existing behaviour.

netfilter: xtables: deconstify struct xt_action_param for matches 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>

netfilter: xtables: change xt_match.checkentry return type Restore function signatures from bool to int so that we can report memory allocation failures or similar using -ENOMEM rather than always having to pass -EINVAL back. This semantic patch may not be too precise (checking for functions that use xt_mtchk_param rather than functions referenced by xt_match.checkentry), but reviewed, it produced the intended result. // <smpl> @@ type bool; identifier check, par; @@ -bool check +int check (struct xt_mtchk_param *par) { ... } // </smpl> Signed-off-by: Jan Engelhardt <jengelh@medozas.de>

netfilter: ebtables: avoid explicit XT_ALIGN() in match/targets This will cause trouble once CONFIG_COMPAT support is added to ebtables. xt_compat_*_offset() calculate the kernel/userland structure size delta using: XT_ALIGN(size) - COMPAT_XT_ALIGN(size) If the match/target sizes are aligned at registration time, delta is always zero. Should have zero effect for existing systems: xtables uses XT_ALIGN() whenever it deals with match/target sizes.

netfilter: xtables: move extension arguments into compound structure (1/6) 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).

[NETFILTER]: Rename init functions. Every netfilter module uses `init' for its module_init() function and `fini' or `cleanup' for its module_exit() function. Problem is, this creates uninformative initcall_debug output and makes ctags rather useless. So go through and rename them all to $(filename)_init and $(filename)_fini.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
