2012-01-039p: propagate umode_tAl Viro1-1/+1
Signed-off-by: Al Viro <[email protected]>
2012-01-03switch ->mknod() to umode_tAl Viro1-3/+3
Signed-off-by: Al Viro <[email protected]>
2012-01-03switch ->create() to umode_tAl Viro1-2/+2
vfs_create() ignores everything outside of 16bit subset of its mode argument; switching it to umode_t is obviously equivalent and it's the only caller of the method Signed-off-by: Al Viro <[email protected]>
2012-01-03switch vfs_mkdir() and ->mkdir() to umode_tAl Viro1-1/+1
vfs_mkdir() gets int, but immediately drops everything that might not fit into umode_t and that's the only caller of ->mkdir()... Signed-off-by: Al Viro <[email protected]>
2011-11-02filesystems: add set_nlink()Miklos Szeredi1-2/+2

2011-09-06fs/9p: Add OS dependent open flags in 9p protocolAneesh Kumar K.V1-1/+54
Some of the flags are OS/arch dependent we add a 9p protocol value which maps to asm-generic/fcntl.h values in Linux Based on the original patch from Venkateswararao Jujjuri <[email protected]> Signed-off-by: Aneesh Kumar K.V <[email protected]>
2011-09-06fs/9p: Don't update file type when updating file attributesAneesh Kumar K.V1-8/+15
We should only update attributes that we can change on stat2inode. Also do file type initialization in v9fs_init_inode. Signed-off-by: Aneesh Kumar K.V <[email protected]> Signed-off-by: Eric Van Hensbergen <[email protected]>
2011-09-06fs/9p: Add fid before dentry instantiationAneesh Kumar K.V1-4/+4
d_instantiate marks the dentry positive. So a parallel lookup and mkdir of the directory can find dentry that doesn't have fid attached. This can result in both the code path doing v9fs_fid_add which results in v9fs_dentry leak. Signed-off-by: Aneesh Kumar K.V <[email protected]> Signed-off-by: Eric Van Hensbergen <[email protected]>

2011-07-25fs: take the ACL checks to common codeChristoph Hellwig1-2/+2
Replace the ->check_acl method with a ->get_acl method that simply reads an ACL from disk after having a cache miss. This means we can replace the ACL checking boilerplate code with a single implementation in namei.c. Signed-off-by: Christoph Hellwig <[email protected]> Signed-off-by: Al Viro <[email protected]>

2011-07-23fs/9p: Always ask new inode in createAneesh Kumar K.V1-9/+21
This make sure we don't end up reusing the unlinked inode object. The ideal way is to use inode i_generation. But i_generation is not available in userspace always. Signed-off-by: Aneesh Kumar K.V <[email protected]> Signed-off-by: Eric Van Hensbergen <[email protected]>
2011-07-23fs/9p: When doing inode lookup compare qid details and inode mode bits.Aneesh Kumar K.V1-4/+37
This make sure we don't use wrong inode from the inode hash. The inode number of the file deleted is reused by the next file system object created and if we only use inode number for inode hash lookup we could end up with wrong struct inode. Also compare inode generation number. Not all Linux file system provide st_gen in userspace. So it could be 0; Signed-off-by: Aneesh Kumar K.V <[email protected]> Signed-off-by: Eric Van Hensbergen <[email protected]>

2011-03-22fs/9p: Attach writeback_fid on first open with WR flagAneesh Kumar K.V1-1/+2
We don't need writeback fid if we are only doing O_RDONLY open Signed-off-by: Aneesh Kumar K.V <[email protected]> Signed-off-by: Venkateswararao Jujjuri <[email protected]> Signed-off-by: Eric Van Hensbergen <[email protected]>
2011-03-22fs/9p: Use truncate_setsize instead of vmtruncateAneesh Kumar K.V1-7/+5
convert vmtruncate usage to truncate_setsize. We also writeback all dirty pages before doing 9p operations and on success call truncate_setsize. This ensure that we continue sanely on failed truncate on the server. The disadvantage is that we are now going to write back the content that get thrown away later as a part of truncate.

2011-03-22fs/9p: Fix race in initializing writeback fidAneesh Kumar K.V1-0/+3
When two process open the same file we can end up with both of them allocating the writeback_fid. Add a new mutex which can be used for synchronizing v9fs_inode member values.

2011-03-15fs/9p: Writeback dirty data before setattrAneesh Kumar K.V1-0/+4
change file attribute can result in making the file readonly. So flush the dirty pages before that. Signed-off-by: Aneesh Kumar K.V <[email protected]> Signed-off-by: Venkateswararao Jujjuri <[email protected]> Signed-off-by: Eric Van Hensbergen <[email protected]>
2011-03-15fs/9p: call vmtruncate before setattr 9p opeationAneesh Kumar K.V1-5/+4
We need to call vmtruncate before 9p setattr operation, otherwise we could write back some dirty pages between setattr with ATTR_SIZE and vmtruncate causing some truncated pages to be written back to server Signed-off-by: Aneesh Kumar K.V <[email protected]> Signed-off-by: Venkateswararao Jujjuri <[email protected]> Signed-off-by: Eric Van Hensbergen <[email protected]>
2011-03-15fs/9p: Properly update inode attributes on linkAneesh Kumar K.V1-9/+1
With caching enabled, we need to make sure we don't update inode->i_size via stat2inode because we could have dirty data which is not yet written to the server Signed-off-by: Aneesh Kumar K.V <[email protected]> Signed-off-by: Venkateswararao Jujjuri <[email protected]> Signed-off-by: Eric Van Hensbergen <[email protected]>
2011-03-15fs/9p: Mark directory inode invalid for many directory inode operationsAneesh Kumar K.V1-9/+14

2011-03-15fs/9p: mark inode attribute invalid on rename, unlink and setattrAneesh Kumar K.V1-0/+1
rename, unlink and setattr can result in update of inode attribute. So mark the cached copy invalid Signed-off-by: Aneesh Kumar K.V <[email protected]> Signed-off-by: Venkateswararao Jujjuri <[email protected]> Signed-off-by: Eric Van Hensbergen <[email protected]>
2011-03-15fs/9p: Add support for marking inode attribute invalidAneesh Kumar K.V1-0/+27
With cached mode some of the file system operation result in updating inode attributes (ctime). Add support for marking inode attribute invalid in such cases so that we fetch the updated inode attribute on dentry revalidation.

2011-03-15fs/9p: Add v9fs_inodeAneesh Kumar K.V1-7/+7
Switch to the fscache code to v9fs_inode. We will later use v9fs_inode in cache=loose mode to track the inode cache validity timeout. Ie if we find an inode in cache older that a specific jiffie range we will consider it stale Signed-off-by: Aneesh Kumar K.V <[email protected]> Signed-off-by: Venkateswararao Jujjuri <[email protected]> Signed-off-by: Eric Van Hensbergen <[email protected]>
2011-03-15fs/9p: Don't set stat.st_blocks based on nrpagesAneesh Kumar K.V1-3/+4
simple_getattr does set stat.st_blocks to a value derived from nrpages. That is not correct with 9p Signed-off-by: Aneesh Kumar K.V <[email protected]> Signed-off-by: Venkateswararao Jujjuri <[email protected]> Signed-off-by: Eric Van Hensbergen <[email protected]>
2011-03-15fs/9p: Add inode hashingAneesh Kumar K.V1-23/+46
We didn't add the inode to inode hash in 9p. We need to do that to get sync to work, otherwise __mark_inode_dirty will not add the inode to super block's dirty list.

2011-01-11fs/9p: Don't set dentry->d_op in create routinesAneesh Kumar K.V1-13/+0
We do set dentry->d_op in lookup even in case of EOENT entries. That implies we should have dentry->d_op already set when create/mkdir/mknod/link/symlink routines are called Signed-off-by: Aneesh Kumar K.V <[email protected]> Signed-off-by: Eric Van Hensbergen <[email protected]>
