2018-08-03netfilter: bridge: Expose nf_tables bridge hook priorities through uapiMáté Eckl1-0/+1
Netfilter exposes standard hook priorities in case of ipv4, ipv6 and arp but not in case of bridge. This patch exposes the hook priority values of the bridge family (which are different from the formerly mentioned) via uapi so that they can be used by user-space applications just like the others.

2017-09-29netfilter: ebtables: fix race condition in frame_filter_net_init()Artem Savkov1-2/+2
It is possible for ebt_in_hook to be triggered before ebt_table is assigned resulting in a NULL-pointer dereference. Make sure hooks are registered as the last step.

2017-07-31netfilter: nf_hook_ops structs can be constFlorian Westphal1-1/+1
We no longer place these on a list so they can be const. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2017-04-26ebtables: remove nf_hook_register usageFlorian Westphal1-12/+3
Similar to ip_register_table, pass nf_hook_ops to ebt_register_table(). This allows to handle hook registration also via pernet_ops and allows us to avoid use of legacy register_hook api. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

2015-10-16netfilter: remove hook owner refcountingFlorian Westphal1-3/+0
since commit 8405a8fff3f8 ("netfilter: nf_qeueue: Drop queue entries on nf_unregister_hook") all pending queued entries are discarded. So we can simply remove all of the owner handling -- when module is removed it also needs to unregister all its hooks.

2015-09-18netfilter: Pass priv instead of nf_hook_ops to netfilter hooksEric W. Biederman1-2/+2
Only pass the void *priv parameter out of the nf_hook_ops. That is all any of the functions are interested now, and by limiting what is passed it becomes simpler to change implementation details.

2015-09-18netfilter: ebtables: Simplify the arguments to ebt_do_tableEric W. Biederman1-4/+2
Nearly everything thing of interest to ebt_do_table is already present in nf_hook_state. Simplify ebt_do_table by just passing in the skb, nf_hook_state, and the table. This make the code easier to read and maintenance easier. To support this create an nf_hook_state on the stack in ebt_broute (the only caller without a nf_hook_state already available). This new nf_hook_state adds no new computations to ebt_broute, but does use a few more bytes of stack. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2015-09-17netfilter: Use nf_hook_state.netEric W. Biederman1-2/+2
Instead of saying "net = dev_net(state->in?state->in:state->out)" just say "state->net". As that information is now availabe, much less confusing and much less error prone. Signed-off-by: "Eric W. Biederman" <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* return ebt_table from ebt_register_table(), module code will save it into per-netns data for unregistration * duplicate ebt_table at the very beginning of registration -- it's added into list, so one ebt_table wouldn't end up in many lists (and each netns has different one) * introduce underscored tables in individial modules, this is temporary to not break bisection.

2006-03-28[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.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+123
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!
