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.

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:

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. Signed-off-by:

Extend the XFRM framework so that endpoint address(es) in the XFRM databases could be dynamically updated according to a request (MIGRATE message) from user application. Target XFRM policy is first identified by the selector in the MIGRATE message. Next, the endpoint addresses of the matching templates and XFRM states are updated according to the MIGRATE message.

Do liberal tracking (only RSTs need to be in-window) for connections picked up without seeing a SYN to deal with window scaling. Also change logging of invalid packets not to log packets accepted by liberal tracking to avoid spamming the logs. Based on suggestion from James Ralston <ralston@pobox.com> Signed-off-by:

This is nf_conntrack_sane, a netfilter connection tracking helper module for the SANE protocol used by the 'saned' daemon to make scanners available via network. The SANE protocol uses separate control & data connections, similar to passive FTP. The helper module is needed to recognize the data connection as RELATED to the control one. Signed-off-by:

Add checksum default defines for mobility header(MH) which goes through raw socket. As the result kernel's behavior is to handle MH checksum as default. This patch also removes verifying inbound MH checksum at mip6_mh_filter() since it did not consider user specified checksum offset and was redundant check with raw socket code. Signed-off-by:
