* [NETFILTER]: Rename init functions.Andrew Morton2006-03-2828-113/+113
| | | | | | | | | | | | | | 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.

* [PATCH] Notifier chain update: API changesAlan Stern2006-03-271-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel's implementation of notifier chains is unsafe. There is no protection against entries being added to or removed from a chain while the chain is in use. The issues were discussed in this thread: http://marc.theaimsgroup.com/?l=linux-kernel&m=113018709002036&w=2 We noticed that notifier chains in the kernel fall into two basic usage classes: "Blocking" chains are always called from a process context and the callout routines are allowed to sleep; "Atomic" chains can be called from an atomic context and the callout routines are not allowed to sleep. We decided to codify this distinction and make it part of the API. Therefore this set of patches introduces three new, parallel APIs: one for blocking notifiers, one for atomic notifiers, and one for "raw" notifiers (which is really just the old API under a new name). New kinds of data structures are used for the heads of the chains, and new routines are defined for registration, unregistration, and calling a chain. The three APIs are explained in include/linux/notifier.h and their implementation is in kernel/sys.c. With atomic and blocking chains, the implementation guarantees that the chain links will not be corrupted and that chain callers will not get messed up by entries being added or removed. For raw chains the implementation provides no guarantees at all; users of this API must provide their own protections. (The idea was that situations may come up where the assumptions of the atomic and blocking APIs are not appropriate, so it should be possible for users to handle these things in their own way.) There are some limitations, which should not be too hard to live with. For atomic/blocking chains, registration and unregistration must always be done in a process context since the chain is protected by a mutex/rwsem. Also, a callout routine for a non-raw chain must not try to register or unregister entries on its own chain. (This did happen in a couple of places and the code had to be changed to avoid it.) Since atomic chains may be called from within an NMI handler, they cannot use spinlocks for synchronization. Instead we use RCU. The overhead falls almost entirely in the unregister routine, which is okay since unregistration is much less frequent that calling a chain. Here is the list of chains that we adjusted and their classifications. None of them use the raw API, so for the moment it is only a placeholder.

If they are, please let us know or submit a patch to fix them. Note that any chain that gets called very frequently should be atomic, because the rwsem read-locking used for blocking chains is very likely to incur cache misses on SMP systems. (However, if the chain's callout routines may sleep then the chain cannot be atomic.) The patch set was written by Alan Stern and Chandra Seetharaman, incorporating material written by Keith Owens and suggestions from Paul McKenney and Andrew Morton.

* [NETFILTER]: ctnetlink: Fix expectaction mask dumpingPablo Neira Ayuso2006-03-221-22/+62
| | | | | | | | | | | | | | | | | | | | The expectation mask has some particularities that requires a different handling. The protocol number fields can be set to non-valid protocols, ie. l3num is set to 0xFFFF. Since that protocol does not exist, the mask tuple will not be dumped. Moreover, this results in a kernel panic when nf_conntrack accesses the array of protocol handlers, that is PF_MAX (0x1F) long. This patch introduces the function ctnetlink_exp_dump_mask, that correctly dumps the expectation mask. Such function uses the l3num value from the expectation tuple that is a valid layer 3 protocol number. The value of the l3num mask isn't dumped since it is meaningless from the userspace side.

* [NETFILTER] nf_conntrack: clean up to reduce size of 'struct nf_conn'Harald Welte2006-03-205-89/+80
| | | | | | | | | | | | | | | | | | | | This patch moves all helper related data fields of 'struct nf_conn' into a separate structure 'struct nf_conn_help'. This new structure is only present in conntrack entries for which we actually have a helper loaded. Also, this patch cleans up the nf_conntrack 'features' mechanism to resemble what the original idea was: Just glue the feature-specific data structures at the end of 'struct nf_conn', and explicitly re-calculate the pointer to it when needed rather than keeping pointers around. Saves 20 bytes per conntrack on my x86_64 box. A non-helped conntrack is 276 bytes. We still need to save another 20 bytes in order to fit into to target of 256bytes.
