There's actually just one type of channel and session, so we don't need the
generic callback functions.
|
|
Remove fuse_chan_bufsize() from the lowlevel API.
fuse_session_receive_buf() is now responsible for allocating memory for the
buffer.
|
|
Move the fuse_chan_ops.send and .receive implementations to fuse_lowlevel.c. The abstraction wasn't actually useful and made the the splice implementation more difficult.
Remove fuse_chan_ops.send and fuse_chan_ops.receive.
|
|
Clean up fuse_chan related interfaces. Remove the following from the
lowlevel library API:
struct fuse_chan_ops;
fuse_chan_new();
fuse_chan_session();
fuse_chan_recv();
fuse_chan_send();
|
|
Clean up fuse_session related interfaces. Remove the following from the
lowlevel library API:
struct fuse_session_ops;
fuse_session_new();
fuse_session_process();
fuse_session_data();

- fuse_kern_unmount closes handle (e.g. 19)
- a thread in my process opens a file - the OS assigns newly freed
handle (i.e. 19)
- fuse_kern_chan_destroy closes the same handle (i.e. 19)
- a thread in my process opens another file - the OS assigns newly
freed handle (i.e. 19)
- * MAYHEM *

This switches the -o no_readdirplus option to a tristate
string: -o readdirplus=(yes|no|auto)
Telling the kernel to always use readdirplus is beneficial to
filesystems (e.g. GlusterFS) where the cost to perform readdir
and readdirplus are identical.
The default remains "auto" (if supported).

This patch implements readdirplus support in FUSE usersapce. It adds
a new fuse lowlevel operations fuse_lowleve_ops::readdir_plus,
corespoding mount options and helper functions to maintain buffer.
[From: Eric Wong <normalperson@yhbt.net>]
This makes our terminology consistent with NFS and
our kernel module, as well as reducing user/developer
confusion in the command-line.
Note: I'm keeping "fuse_add_direntry_plus" since that is
less standardized in its use than "readdirplus" for now.

Several caching logic changes have been made on the kernel side
to better support network-based fuse filesystems. These include
kernel side mtime checking and read path cache revalidation. The
new caching logic is enabled through the FUSE_AUTO_INVAL_DATA
init flag. Export this to the user via the '[no_]auto_inval_data'
mount option.

This fixes problems with emulating flock() with POSIX locking.
Reported by Sebastian Pipping.
As with lock/setlk/getlk most filesystems don't need to implement
this, as the kernel takes care of file locking. The only reason to
implement locking operations is for network filesystems which want
file locking to work between clients.

This works similar to "noforget" except that eventually the node will
be allowed to expire from the cache.
|
|
Fix the ambiguity of ioctl ABI on the kernel/userspace boundary
for 32bit vs. 64bit userspace
|
|
Disable splice by default, add "splice_read", "splice_write" and
"splice_move" options. Keep the "no_splice_*" variants, which can
disable splice even if the filesystem explicitly enables it.
|
|
Retrieve data stored in the kernel buffers for a given inode.
|
|
Add new ->write_buf() method to low level interface. This
allows passig a generic buffer, either containing a memory buffer
or a file descriptor. This allows implementing zero copy writes.
Add fuse_session_receive_buf() and fuse_session_process_buf()
which may be used in event loop implementations to replace
fuse_chan_recv() and fuse_session_process() respectively.
|
|
Add a generic buffer interface for use with I/O. Buffer vectors are
supplied and each buffer in the vector may be a memory pointer or a
file descriptor.
The fuse_reply_fd() interface is converted to using buffers.
