2010-10-29fix open/umount raceAl Viro
nameidata_to_filp() drops nd->path or transfers it to opened file. In the former case it's a Bad Idea(tm) to do mnt_drop_write() on nd->path.mnt, since we might race with umount and vfsmount in question might be gone already. Fix: don't drop it, then... IOW, have nameidata_to_filp() grab nd->path in case it transfers it to file and do path_drop() in callers. After they are through with accessing nd->path...

authentication Removed following fields from smb session structure cryptkey, ntlmv2_hash, tilen, tiblob and ntlmssp_auth structure is allocated dynamically only if the auth mech in NTLMSSP. response field within a session_key structure is used to initially store the target info (either plucked from type 2 challenge packet in case of NTLMSSP or fabricated in case of NTLMv2 without extended security) and then to store Message Authentication Key (mak) (session key + client response). Server challenge or cryptkey needed during a NTLMSSP authentication is now part of ntlmssp_auth structure which gets allocated and freed once authenticaiton process is done.

2010-10-29NTLM auth and sign - Use appropriate server challengeShirish Pargaonkar
Need to have cryptkey or server challenge in smb connection (struct TCP_Server_Info) for ntlm and ntlmv2 auth types for which cryptkey (Encryption Key) is supplied just once in Negotiate Protocol response during an smb connection setup for all the smb sessions over that smb connection. For ntlmssp, cryptkey or server challenge is provided for every smb session in type 2 packet of ntlmssp negotiation, the cryptkey provided during Negotiation Protocol response before smb connection does not count. Rename cryptKey to cryptkey and related changes. Signed-off-by: Shirish Pargaonkar <shirishpargaonkar@gmail.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

2010-10-28ext4: BUG_ON fix: check if page has buffers before calling page_buffers() Theodore Ts'o
We need to make check if a page does not have buffes by checking page_has_buffers(page) before calling page_buffers(page) in ext4_writepage(). Otherwise page_buffers() could throw a BUG_ON.

2010-10-28Btrfs: create special free space cache inodeJosef Bacik
In order to save free space cache, we need an inode to hold the data, and we need a special item to point at the right inode for the right block group. So first, create a special item that will point to the right inode, and the number of extent entries we will have and the number of bitmaps we will have. We truncate and pre-allocate space everytime to make sure it's uptodate. This feature will be turned on as soon as you mount with -o space_cache, however it is safe to boot into old kernels, they will just generate the cache the old fashion way. When you boot back into a newer kernel we will notice that we modified and not the cache and automatically discard the cache. Signed-off-by: Josef Bacik <josef@redhat.com>
