Move the iovec handling entirely into read_from_socket. That simplifies the code and gets rid of the special handling for header reads. With this we can also get rid of the "goto incomplete_rcv" label in the main demultiplex thread function since we can now treat header and non-header receives the same way. Also, make it return an int (since we'll never receive enough to worry about the sign bit anyway), and simply make it return the amount of bytes read or a negative error code.

Add data structures and functions necessary to map a uid and gid to SID. These functions are very similar to the ones used to map a SID to uid and gid. This time, instead of storing sid to id mapping sorted on a sid value, id to sid is stored, sorted on an id. A cifs upcall sends an id (uid or gid) and expects a SID structure in return, if mapping was done successfully. A failed id to sid mapping to EINVAL. This patchset aims to enable chown and chgrp commands when cifsacl mount option is specified, especially to Windows SMB servers. Currently we can't do that. So now along with chmod command, chown and chgrp work. Winbind is used to map id to a SID. chown and chgrp use an upcall to provide an id to winbind and upcall returns with corrosponding SID if any exists. That SID is used to build security descriptor. The DACL part of a security descriptor is not changed by either chown or chgrp functionality. cifs client maintains a separate caches for uid to SID and gid to SID mapping. This is similar to the one used earlier to map SID to id (as part of ID mapping code). I tested it by mounting shares from a Windows (2003) server by authenticating as two users, one at a time, as Administrator and as a ordinary user. And then attempting to change owner of a file on the share. Depending on the permissions/privileges at the server for that file, chown request fails to either open a file (to change the ownership) or to set security descriptor. So it all depends on privileges on the file at the server and what user you are authenticated as at the server, cifs client is just a conduit. I compared the security descriptor during chown command to that what smbcacls sends when it is used with -M OWNNER: option and they are similar.

Add mount options backupuid and backugid. It allows an authenticated user to access files with the intent to back them up including their ACLs, who may not have access permission but has "Backup files and directories user right" on them (by virtue of being part of the built-in group Backup Operators. When mount options backupuid is specified, cifs client restricts the use of backup intents to the user whose effective user id is specified along with the mount option. When mount options backupgid is specified, cifs client restricts the use of backup intents to the users whose effective user id belongs to the group id specified along with the mount option. If an authenticated user is not part of the built-in group Backup Operators at the server, access to such files is denied, even if allowed by the client.

Thus spake Jeff Layton: "Making that a module parm would allow you to set that parameter at boot time without needing to add special startup scripts. IMO, all of the procfile "switches" under /proc/fs/cifs should be module parms instead." This patch doesn't alter the default behavior (Oplocks are enabled by default). To disable oplocks when loading the module, use modprobe cifs enable_oplocks=0 (any of '0' or 'n' or 'N' conventions can be used). To disable oplocks at runtime using the new interface, use echo 0 > /sys/module/cifs/parameters/enable_oplocks The older /proc/fs/cifs/OplockEnabled interface will be deprecated after two releases. A subsequent patch will add an warning message about this deprecation. Changes since v2: - make enable_oplocks a 'bool' Changes since v1: - eliminate the use of extra variable by renaming the old one to enable_oplocks and make it an 'int' type.

The variable names in this function are so ambiguous that it's very difficult to know what it's doing. Rename them to make it a bit more clear. Also, remove a redundant length check. cifsd checks to make sure that the rfclen isn't larger than the maximum frame size when it does the receive. Finally, change checkSMB to return a real error code (-EIO) when it finds an error. That will help simplify some coming changes in the callers.

server->maxBuf is the maximum SMB size (including header) that the server can handle. CIFSMaxBufSize is the maximum amount of data (sans header) that the client can handle. Currently maxBuf is being capped at CIFSMaxBufSize + the max headers size, and the two values are used somewhat interchangeably in the code. This makes little sense as these two values are not related at all. Separate them and make sure the code uses the right values in the right places.

A couple of changes to the Tegra maintainership setup: I'm very glad to bring on Stephen Warren on board as a maintainer. The work he has done so far is excellent, and the fact that he works for Nvidia means he has long-term interest in the platform. Erik Gilling did an astounding amount of work on getting things up and running but has been a silent partner on the maintainership side for a while, and is stepping down. Thanks for your contributions so far, Erik. Finally, update the git URL since I'll take over running the main repo for a while. Overall maintainership model isn't changing much at this time: We'll all three review patches as appropriate, and one of us will collect the main repo (me at this time).
