fuse: initialize fc->release before calling it

2015-09-18T11:52:15Z

commit 0ad0b3255a08020eaf50e34ef0d6df5bdf5e09ed upstream. fc->release is called from fuse_conn_put() which was used in the error cleanup before fc->release was initialized. [Jeremiah Mahler : assign fc->release after calling fuse_conn_init(fc) instead of before.] Signed-off-by: Miklos Szeredi Fixes: a325f9b92273 ("fuse: update fuse_conn_init() and separate out fuse_conn_kill()") Signed-off-by: Ben Hutchings (cherry picked from commit 1a713f9828a6abd288ecc9eef0bbe5c56d0ffc0b) Signed-off-by: Willy Tarreau

fuse: fix stat call on 32 bit platforms

2012-10-07T21:37:54Z

commit 45c72cd73c788dd18c8113d4a404d6b4a01decf1 upstream. Now we store attr->ino at inode->i_ino, return attr->ino at the first time and then return inode->i_ino if the attribute timeout isn't expired. That's wrong on 32 bit platforms because attr->ino is 64 bit and inode->i_ino is 32 bit in this case. Fix this by saving 64 bit ino in fuse_inode structure and returning it every time we call getattr. Also squash attr->ino into inode->i_ino explicitly.

truncate: use new helpers

2009-09-24T12:41:47Z

Update some fs code to make use of new helper functions introduced in the previous patch. Should be no significant change in behaviour (except CIFS now calls send_sig under i_lock, via inode_newsize_ok).

Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse

2009-09-18T16:23:03Z

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mszeredi/fuse: fuse: add fusectl interface to max_background fuse: limit user-specified values of max background requests fuse: use drop_nlink() instead of direct nlink manipulation fuse: document protocol version negotiation fuse: make the number of max background requests and congestion threshold tunable

fs: Assign bdi in super_block

2009-09-16T13:18:51Z

We do this automatically in get_sb_bdev() from the set_bdev_super() callback. Filesystems that have their own private backing_dev_info must assign that in ->fill_super(). Note that ->s_bdi assignment is required for proper writeback! Acked-by: Christoph Hellwig Signed-off-by: Jens Axboe

fuse: add fusectl interface to max_background

2009-09-16T12:15:29Z

Make the max_background and congestion_threshold parameters of a FUSE mount tunable at runtime by adding the respective knobs to its directory within the fusectl filesystem. Signed-off-by: Csaba Henk Signed-off-by: Miklos Szeredi

fuse: limit user-specified values of max background requests

2009-09-16T12:15:29Z

An untrusted user could DoS the system if s/he were allowed to accumulate an arbitrary number of pending background requests by setting the above limits to extremely high values in INIT. This patch excludes this possibility by imposing global upper limits on the possible values of per-mount "max background requests" and "congestion threshold" parameters for unprivileged FUSE filesystems. These global limits are implemented as module parameters. Signed-off-by: Csaba Henk Signed-off-by: Miklos Szeredi

writeback: add name to backing_dev_info

2009-09-11T07:20:26Z

This enables us to track who does what and print info. Its main use is catching dirty inodes on the default_backing_dev_info, so we can fix that up. Signed-off-by: Jens Axboe

fuse: make the number of max background requests and congestion threshold tunable

2009-07-07T15:28:52Z

The practical values for these limits depend on the design of the filesystem server so let userspace set them at initialization time. Signed-off-by: Csaba Henk Signed-off-by: Miklos Szeredi

fuse: invalidation reverse calls

2009-06-30T18:12:24Z

Add notification messages that allow the filesystem to invalidate VFS caches. Two notifications are added: 1) inode invalidation - invalidate cached attributes - invalidate a range of pages in the page cache (this is optional) 2) dentry invalidation - try to invalidate a subtree in the dentry cache Care must be taken while accessing the 'struct super_block' for the mount, as it can go away while an invalidation is in progress. To prevent this, introduce a rw-semaphore, that is taken for read during the invalidation and taken for write in the ->kill_sb callback. Cc: Csaba Henk Cc: Anand Avati Signed-off-by: Miklos Szeredi
