* [INET]: Consolidate xxx_the secret_rebuildPavel Emelyanov2007-10-154-90/+50
| | | | | | | | | | | | | | | This code works with the generic data types as well, so move this into inet_fragment.c This move makes it possible to hide the secret_timer management and the secret_rebuild routine completely in the inet_fragment.c Introduce the ->hashfn() callback in inet_frags() to get the hashfun for a given inet_frag_queue() object.

* [INET]: Consolidate the xxx_frag_killPavel Emelyanov2007-10-154-66/+26
| | | | | | | | | | | Since now all the xxx_frag_kill functions now work with the generic inet_frag_queue data type, this can be moved into a common place. The xxx_unlink() code is moved as well. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>
* [INET]: Collect common frag sysctl variables togetherPavel Emelyanov2007-10-156-58/+68
| | | | | | | | | | | | | | | | | Some sysctl variables are used to tune the frag queues management and it will be useful to work with them in a common way in the future, so move them into one structure, moreover they are the same for all the frag management codes. I don't place them in the existing inet_frags object, introduced in the previous patch for two reasons: 1. to keep them in the __read_mostly section; 2. not to export the whole inet_frags objects outside.

* [INET]: Collect frag queues management objects togetherPavel Emelyanov2007-10-157-175/+205
| | | | | | | | | | | | | | | | | | | | | | | | | | | There are some objects that are common in all the places which are used to keep track of frag queues, they are: * hash table * LRU list * rw lock * rnd number for hash function * the number of queues * the amount of memory occupied by queues * secret timer Move all this stuff into one structure (struct inet_frags) to make it possible use them uniformly in the future. Like with the previous patch this mostly consists of hunks like - write_lock(&ipfrag_lock); + write_lock(&ip4_frags.lock); To address the issue with exporting the number of queues and the amount of memory occupied by queues outside the .c file they are declared in, I introduce a couple of helpers.

* [INET]: Move common fields from frag_queues in one place.Pavel Emelyanov2007-10-153-250/+217
| | | | | | | | | | | | | | | | | | | | | Introduce the struct inet_frag_queue in include/net/inet_frag.h file and place there all the common fields from three structs: * struct ipq in ipv4/ip_fragment.c * struct nf_ct_frag6_queue in nf_conntrack_reasm.c * struct frag_queue in ipv6/reassembly.c After this, replace these fields on appropriate structures with this structure instance and fix the users to use correct names i.e. hunks like - atomic_dec(&fq->refcnt); + atomic_dec(&fq->q.refcnt); (these occupy most of the patch) Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S.

* [IPV4]: Uninline netfilter okfnsPatrick McHardy2007-10-153-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | Now that we don't pass double skb pointers to nf_hook_slow anymore, gcc can generate tail calls for some of the netfilter hook okfn invocations, so there is no need to inline the functions anymore. This caused huge code bloat since we ended up with one inlined version and one out-of-line version since we pass the address to nf_hook_slow.

* [NET]: Avoid copying TCP packets unnecessarilyHerbert Xu2007-10-151-11/+10
| | | | | | | | | | | | | | | TCP packets all have writable heads, that is, even though it's cloned, it is writable up to the end of the TCP header. This patch makes skb_checksum_help aware of this fact by using skb_clone_writable and avoiding a copy for TCP. I've also modified the BUG_ON tests to be unsigned. The only case where this makes a difference is if csum_start points to a location before skb->data. Since skb->data should always include the header where the checksum field is (and all currently callers adhere to that), this change is safe and may uncover bugs later.

* [BRIDGE]: Unshare skb upon entryHerbert Xu2007-10-151-0/+4
| | | | | | | | | | Due to the special location of the bridging hook, it should never see a shared packet anyway (certainly not with any in-kernel code).

| | | | | | | | | | | | | This patch is a bit of a hack. However it is worth it if you consider that this is the only reason why we have to carry around the struct sk_buff ** pointers in netfilter. It makes ip_defrag always return the packet that was given to it on input. It does this by cloning the packet and replacing its original contents with the head fragment if necessary.

| | | | | | | | | | | | | This patch creates a new function skb_morph that's just like skb_clone except that it lets user provide the spare skb that will be overwritten by the one that's to be cloned. This will be used by IP fragment reassembly so that we get back the same skb that went in last (rather than the head skb that we get now which requires us to carry around double pointers all over the place).

* [SKBUFF]: Merge common code between copy_skb_header and skb_cloneHerbert Xu2007-10-151-71/+45
| | | | | | | | | | | | | | | | This patch creates a new function __copy_skb_header to merge the common code between copy_skb_header and skb_clone. Having two functions which are largely the same is a source of wasted labour as well as confusion. In fact the tc_verd stuff is almost certainly a bug since it's treated differently in skb_clone compared to the callers of copy_skb_header (skb_copy/pskb_copy/skb_copy_expand).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The purpose of an RPC ping (a NULL request) is to determine whether the remote end is operating and supports the RPC program and version of the request.

| * SUNRPC: Add a new error code for retry waiting for another binderChuck Lever2007-10-092-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add new error code processing to the kernel's rpcbind client and to call_bind_status() to distinguish two cases: Case 1: the remote has replied that the program/version tuple is not registered (returns -EACCES) Case 2: another process is already in the middle of binding on this transport (now returns -EAGAIN) This change allows more specific retry processing for each of these two cases.
