2008-02-06smbfs: fix calculation of kernel_recvmsg size parameter in smb_receive()Jeff Layton
smb_receive calls kernel_recvmsg with a size that's the minimum of the amount of buffer space in the kvec passed in or req->rq_rlen (which represents the length of the response). This does not take into account any data that was read in a request earlier pass through smb_receive. If the first pass through smb_receive receives some but not all of the response, then the next pass can call kernel_recvmsg with a size field that's too big. kernel_recvmsg can overrun into the next response, throwing off the alignment and making it unrecognizable. This causes messages like this to pop up in the ring buffer: smb_get_length: Invalid NBT packet, code=69 as well as other errors indicating that the response is unrecognizable. Typically this is seen on a smbfs mount under heavy I/O. This patch changes the code to use (req->rq_rlen - req->rq_bytes_recvd) instead instead of just req->rq_rlen, since that should represent the amount of unread data in the response. I think this is correct, but an ACK or NACK from someone more familiar with this code would be appreciated...

2007-05-08header cleaning: don't include smp_lock.h when not usedRandy Dunlap
Remove includes of <linux/smp_lock.h> where it is not used/needed. Suggested by Al Viro. Builds cleanly on x86_64, i386, alpha, ia64, powerpc, sparc, sparc64, and arm (all 59 defconfigs).

2005-08-29[TCP]: Move the tcp sock states to net/tcp_states.hArnaldo Carvalho de Melo
Lots of places just needs the states, not even linux/tcp.h, where this enum was, needs it. This speeds up development of the refactorings as less sources are rebuilt when things get moved from net/tcp.h.

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!
