Applied (whitespace-cleanup) to each file. Having whitespace changes
in the VCS is ugly, but it ensures that in the future committers
can run this function to *avoid* commiting any whitespace.

This should prevent some valgrind warnings.

This creates a separate device file descriptor for each processing thread,
which might improve performance.
|
|
While the request lives don't free the channel associated with the request,
the answer will need to be written on the channel.
|
|
New functions: fuse_chan_get(), fuse_chan_put(). Removed function:
fuse_chan_destroy().

See renameat2() system call in linux-3.15 and later kernels.

This allows the filesystem to specify the time granularity it
supports when the kernel is responsible for updating times
("writeback_cache" option).
|
|
Was broken by commit 561d7054d856 "libfuse: remove fuse_chan_bufsize()".
|
|
Asynchronous direct I/O is supported by linux kernels 3.13 and
later, writeback caching is supported by 3.14 and later.

This allows compiling fuse with musl.
|
|
Valgrind warns on close(-1). So don't do this (happens if fuse_chan_clearfd()
was called on the channel).
|
|
|
|
Remove 'fh_old' which was an ABI compatibility field for a long time.
Make 'writepage' a bitfield.
|
|

|
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_session related interfaces. Remove the following from the
lowlevel library API:
struct fuse_session_ops;
fuse_session_new();
fuse_session_process();
fuse_session_data();

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).
|
|
Make requested poll events available to the filesystem. If the requested
eventsare not available, then this field is zero.
|
|
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.

The FUSE library may be used from any number of programs which
may also fork() + execve(), so set the close-on-exec flag to
avoid inadvertant leakage of pipe file descriptors.
While we're at it, attempt to use pipe2() since this is within a
(currently) Linux-only code path and pipe2() offers thread-safety.

Due to an oversight, splice will never actually be used for i/o. Someone forgot
to #include "config.h" in lib/buffer.c (in fact almost no files include that
header). As a result, even though configure detects splice support and puts
HAVE_SPLICE in config.h, buffer.c is always compiled as if there is no splice
support.
Also add #include "config.h" to fuse.c and fuse_lowlevel.c. These currently
include it indirectly through fuse_misc.h, but we don't want to depend on that.

fallocate filesystem operation preallocates media space for the given file.
If fallocate returns success then any subsequent write to the given range
never fails with 'not enough space' error.

Check protocol version before sending notifications and return -ENOSYS if a
particular notification is not supported.

This partially reverts commit 4b2157c44e6ad7e692fcffb7450143e83151d36b.
Remove mmap/munmap suppor as this missed the interface changes for Linux-3.3
(API version 7.18).
Only revert the mmap/munmap bits and leave the retrieve_reply API fix in place
as well as the optimization in fuse_send_data_iov_fallback().
|
|
Fix memory leak caused by a missing fuse_request_free() in fuse_reply_data().

libfuse part to allow a FUSE file-system to tell the kernel when a
file or directory is deleted. If the specified dentry has the
specified inode number, the kernel will unhash it.

Currently this is only useful for CUSE. Also update retrieve_reply()
method.
