2007-02-09[PATCH] knfsd: fix a race in closing NFSd connectionsNeilBrown
If you lose this race, it can iput a socket inode twice and you get a BUG in fs/inode.c When I added the option for user-space to close a socket, I added some cruft to svc_delete_socket so that I could call that function when closing a socket per user-space request. This was the wrong thing to do. I should have just set SK_CLOSE and let normal mechanisms do the work. Not only wrong, but buggy. The locking is all wrong and it openned up a race where-by a socket could be closed twice. So this patch: Introduces svc_close_socket which sets SK_CLOSE then either leave the close up to a thread, or calls svc_delete_socket if it can get SK_BUSY. Adds a bias to sk_busy which is removed when SK_DEAD is set, This avoid races around shutting down the socket. Changes several 'spin_lock' to 'spin_lock_bh' where the _bh was missing.

2007-02-08[IPX]: Fix NULL pointer dereference on ipx unloadJiri Bohac
Fixes a null pointer dereference when unloading the ipx module. On initialization of the ipx module, registering certain packet types can fail. When this happens, unloading the module later dereferences NULL pointers. This patch fixes that. Please apply. Signed-off-by: Jiri Bohac <jbohac@suse.cz> Signed-off-by: David S.

2007-02-08[NET]: Fix net/socket.c warnings.David S. Miller
GCC (correctly) says: net/socket.c: In function ‘sys_sendto’: net/socket.c:1510: warning: ‘err’ may be used uninitialized in this function net/socket.c: In function ‘sys_recvfrom’: net/socket.c:1571: warning: ‘err’ may be used uninitialized in this function sock_from_file() either returns filp->private_data or it sets *err and returns NULL. Callers return "err" on NULL, but filp->private_data could be NULL. Some minor rearrangements of error handling in sys_sendto and sys_recvfrom solves the issue. Signed-off-by: David S. Miller <davem@davemloft.net>
2007-02-08[NET]: cleanup sock_from_file()Eric Dumazet
I believe dead code from sock_from_file() can be cleaned up. All sockets are now built using sock_attach_fd(), that puts the 'sock' pointer into file->private_data and &socket_file_ops into file->f_op I could not find a place where file->private_data could be set to NULL, keeping opened the file. So to get 'sock' from a 'file' pointer, either : - This is a socket file (f_op == &socket_file_ops), and we can directly get 'sock' from private_data. - This is not a socket, we return -ENOTSOCK and dont even try to find a socket via dentry/inode :) Signed-off-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S.

2007-02-08[NET]: change layout of ehash tableEric Dumazet
ehash table layout is currently this one : First half of this table is used by sockets not in TIME_WAIT state Second half of it is used by sockets in TIME_WAIT state. This is non optimal because of for a given hash or socket, the two chain heads are located in separate cache lines. Moreover the locks of the second half are never used. If instead of this halving, we use two list heads in inet_ehash_bucket instead of only one, we probably can avoid one cache miss, and reduce ram usage, particularly if sizeof(rwlock_t) is big (various CONFIG_DEBUG_SPINLOCK, CONFIG_DEBUG_LOCK_ALLOC settings). So we still halves the table but we keep together related chains to speedup lookups and socket state change. In this patch I did not try to align struct inet_ehash_bucket, but a future patch could try to make this structure have a convenient size (a power of two or a multiple of L1_CACHE_SIZE). I guess rwlock will just vanish as soon as RCU is plugged into ehash :) , so maybe we dont need to scratch our heads to align the bucket... Note : In case struct inet_ehash_bucket is not a power of two, we could probably change alloc_large_system_hash() (in case it use __get_free_pages()) to free the unused space. It currently allocates a big zone, but the last quarter of it could be freed. Again, this should be a temporary 'problem'. Patch tested on ipv4 tcp only, but should be OK for IPV6 and DCCP.

Adds call forwarding to X.25, allowing it to operate like an X.25 router. Useful if one needs to manipulate X.25 traffic with tools like tc. This is an update/cleanup based off a patch submitted by Daniel Ferenci a few years ago. Thanks Alan for the feedback. Added the null check to the clones. Moved the skb_clone's into the forwarding functions. Worked ok with Cisco XoT, linux X.25 back to back, and some old NTUs/PADs.

2007-02-08[ATM]: Fix for crash in adummy_init()Daniel Walker
This was reported by Ingo Molnar here, http://lkml.org/lkml/2006/12/18/119 The problem is that adummy_init() depends on atm_init() , but adummy_init() is called first. So I put atm_init() into subsys_initcall which seems appropriate, and it will still get module_init() if it becomes a module.

2007-02-08[NET]: user of the jiffies rounding code: NetworkingArjan van de Ven
This patch introduces users of the round_jiffies() function in the networking code. These timers all were of the "about once a second" or "about once every X seconds" variety and several showed up in the "what wakes the cpu up" profiles that the tickless patches provide. Some timers are highly dynamic based on network load; but even on low activity systems they still show up so the rounding is done only in cases of low activity, allowing higher frequency timers in the high activity case. The various hardware watchdogs are an obvious case; they run every 2 seconds but aren't otherwise specific of exactly when they need to run.
