* [CIFS] Fix buffer overflow if server sends corrupt response to smallSteve French2007-11-131-21/+70
| | | | | | | | | | | | | | | | | | | request In SendReceive() function in transport.c - it memcpy's message payload into a buffer passed via out_buf param. The function assumes that all buffers are of size (CIFSMaxBufSize + MAX_CIFS_HDR_SIZE) , unfortunately it is also called with smaller (MAX_CIFS_SMALL_BUFFER_SIZE) buffers. There are eight callers (SMB worker functions) which are primarily affected by this change: TreeDisconnect, uLogoff, Close, findClose, SetFileSize, SetFileTimes, Lock and PosixLock CC: Dave Kleikamp <shaggy@austin.ibm.com> CC: Przemyslaw Wegrzyn <czajnik@czajsoft.pl> Acked-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

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!
