* vfs: simple_set_mnt() should return voidSukadev Bhattiprolu2009-03-271-2/+3
| | | | | | | | | | | | | | | | | | | | | | | simple_set_mnt() is defined as returning 'int' but always returns 0. Callers assume simple_set_mnt() never fails and don't properly cleanup if it were to _ever_ fail. For instance, get_sb_single() and get_sb_nodev() should: up_write(sb->s_unmount); deactivate_super(sb); if simple_set_mnt() fails. Since simple_set_mnt() never fails, would be cleaner if it did not return anything.

| * CRED: Wrap task credential accesses in 9P2000 filesystemDavid Howells2008-11-143-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Wrap access to task credentials so that they can be separated more easily from the task_struct during the introduction of COW creds. Change most current->(|e|s|fs)[ug]id to current_(|e|s|fs)[ug]id(). Change some task->e?[ug]id to task_e?[ug]id(). In some places it makes more sense to use RCU directly rather than a convenient wrapper; these will be addressed by later patches.

* 9p: fix device file handlingMagnus Deininger2008-10-171-0/+1
| | | | | | | | | | | | | | | | | | | | | In v9fs_get_inode(), for block, as well as char devices (in theory), the function init_special_inode() is called to set up callback functions for file ops. this function uses the file mode's value to determine whether to use block or char dev functions. In v9fs_inode_from_fid(), the function p9mode2unixmode() is used, but for all devices it initially returns S_IFBLK, then uses v9fs_get_inode() to initialise a new inode, then finally uses v9fs_stat2inode(), which would determine whether the inode is a block or character device. However, at that point init_special_inode() had already decided to use the block device functions, so even if the inode's mode is turned to a character device, the block functions are still used to operate on them. The attached patch simply calls init_special_inode() again for devices after parsing device node data in v9fs_stat2inode() so that the proper functions are used.

* 9p: move dirread to fs layerEric Van Hensbergen2008-10-171-16/+38
| | | | | | | | | | | | | | | | | Currently reading a directory is implemented in the client code. This function is not actually a wire operation, but a meta operation which calls read operations and processes the results. This patch moves this functionality to the fs layer and calls component wire operations instead of constructing their packets. This provides a cleaner separation and will help when we reorganize the client functions and protocol processing methods. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
* 9p: adjust 9p vfs write operationEric Van Hensbergen2008-10-171-7/+29
| | | | | | | | | | | | | Currently, the 9p net wire operation ensures that all data is sent by sending multiple packets if the data requested is larger than the msize. This is better handled in the vfs code so that we can simplify wire operations to being concerned with only putting data onto and taking data off of the wire.

* vfs: Use const for kernel parser tableSteven Whitehouse2008-10-131-1/+1
| | | | | | | | | | | | | | This is a much better version of a previous patch to make the parser tables constant. Rather than changing the typedef, we put the "const" in all the various places where its required, allowing the __initconst exception for nfsroot which was the cause of the previous trouble.

We were incorrectly passing the extended protocol's flag through even in legacy mode. This was reported in bugzilla report #10689.

This patch reorganizes the cleanup to get rid of the bad behavior. This also merges the 9pnet and 9pnet_fd modules for the purpose of configuration and initialization.

* add match_strlcpy() us it to make v9fs make uname and remotename parsing ↵Markus Armbruster2008-05-141-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | more robust match_strcpy() is a somewhat creepy function: the caller needs to make sure that the destination buffer is big enough, and when he screws up or forgets, match_strcpy() happily overruns the buffer. There's exactly one customer: v9fs_parse_options(). I believe it currently can't overflow its buffer, but that's not exactly obvious. The source string is a substing of the mount options. The kernel silently truncates those to PAGE_SIZE bytes, including the terminating zero. See compat_sys_mount() and do_mount(). The destination buffer is obtained from __getname(), which allocates from name_cachep, which is initialized by vfs_caches_init() for size PATH_MAX. We're safe as long as PATH_MAX <= PAGE_SIZE. PATH_MAX is 4096. As far as I know, the smallest PAGE_SIZE is also 4096. Here's a patch that makes the code a bit more obviously correct. It doesn't depend on PATH_MAX <= PAGE_SIZE.

| | | | | | | | | | Loose mode in 9p utilizes the page cache without respecting coherency with the server. Any writes previously invaldiated the entire mapping for a file.

* 9p: attach-per-userLatchesar Ionkov2007-10-174-60/+195
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 9P2000 protocol requires the authentication and permission checks to be done in the file server. For that reason every user that accesses the file server tree has to authenticate and attach to the server separately. Multiple users can share the same connection to the server. Currently v9fs does a single attach and executes all I/O operations as a single user. This makes using v9fs in multiuser environment unsafe as it depends on the client doing the permission checking. This patch improves the 9P2000 support by allowing every user to attach separately. The patch defines three modes of access (new mount option 'access'): - attach-per-user (access=user) (default mode for 9P2000.u) If a user tries to access a file served by v9fs for the first time, v9fs sends an attach command to the server (Tattach) specifying the user. If the attach succeeds, the user can access the v9fs tree. As there is no uname->uid (string->integer) mapping yet, this mode works only with the 9P2000.u dialect. - allow only one user to access the tree (access=<uid>) Only the user with uid can access the v9fs tree. Other users that attempt to access it will get EPERM error. - do all operations as a single user (access=any) (default for 9P2000) V9fs does a single attach and all operations are done as a single user. If this mode is selected, the v9fs behavior is identical with the current one. Signed-off-by: Latchesar Ionkov <lucho@ionkov.net> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>

* Detach sched.h from mm.hAlexey Dobriyan2007-05-214-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | First thing mm.h does is including sched.h solely for can_do_mlock() inline function which has "current" dereference inside. By dealing with can_do_mlock() mm.h can be detached from sched.h which is good. See below, why. This patch a) removes unconditional inclusion of sched.h from mm.h b) makes can_do_mlock() normal function in mm/mlock.c c) exports can_do_mlock() to not break compilation d) adds sched.h inclusions back to files that were getting it indirectly. e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were getting them indirectly Net result is: a) mm.h users would get less code to open, read, preprocess, parse, ... if they don't need sched.h b) sched.h stops being dependency for significant number of files: on x86_64 allmodconfig touching sched.h results in recompile of 4083 files, after patch it's only 3744 (-8.3%).
