2017-05-16ebtables: arpreply: Add the standard target sanity checkGao Feng1-0/+3
The info->target comes from userspace and it would be used directly. So we need to add the sanity check to make sure it is a valid standard target, although the ebtables tool has already checked it. Kernel needs to validate anything coming from userspace. If the target is set as an evil value, it would break the ebtables and cause a panic. Because the non-standard target is treated as one offset. Now add one helper function ebt_invalid_target, and we would replace the macro INVALID_TARGET later.

2016-11-03netfilter: x_tables: move hook state into xt_action_param structurePablo Neira Ayuso1-1/+2
Place pointer to hook state in xt_action_param structure instead of copying the fields that we need. After this change xt_action_param fits into one cacheline. This patch also adds a set of new wrapper functions to fetch relevant hook state structure fields. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2010-03-25netfilter: xtables: change xt_target.checkentry return typeJan Engelhardt1-1/+1
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. // <smpl> @@ type bool; identifier check, par; @@ -bool check +int check (struct xt_tgchk_param *par) { ... } // </smpl> Minus the change it does to xt_ct_find_proto.

2010-02-15netfilter: ebtables: avoid explicit XT_ALIGN() in match/targetsFlorian Westphal1-1/+1
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.

2006-03-29[NETFILTER]: Rename init functions.Andrew Morton1-4/+4
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.

2005-04-17Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds1-0/+97
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!
