2019-03-08Document fuse_fsync_in.fsync_flags and remove magic numbers (#375)Alan Somers-12/+4
2019-02-25hello_ll: Fix null pointer dereference (#363)Forty-Bot-0/+7
If hello_ll is invoked without a mountpoint, it will try to call fuse_session_mount anyway with the NULL mountpoint (which then causes a segfault). Print out a short help message instead (taken from passthrough_ll.c).
2019-01-22passthrough_ll: lo_create() should honor CACHE_NEVER (#345)Miklos Szeredi-0/+5
lo_create() did not honour CACHE_NEVER in lo_create(), which has an effect on how I/O is performed after the open. The value of CACHE_ALWAYS, which results in setting fi->keep_cache, only has an effect for the state of the cache at open, and since the file was just created the cache is always empty. Hence setting this doesn't have an effect on lo_create(), but keep it for symmetry with lo_open().
2018-12-29Fixed memory leak.Nikolaus Rath-5/+0
Fixes: #338.
2018-11-27Fix fd/inode leakNikolaus Rath-13/+19
If do_readdir() calls do_lookup(), but the latter fails, we still have to return any entries that we already stored in the readdir buffer to avoid leaking inodes. do_lookup() may fail if e.g. we reach the file descriptor limit.

2018-11-24Fixed lookup-count leak in do_readdir().Nikolaus Rath-3/+7

Fixes: #327
2018-11-19examples: add copy_file_range() support to passthrough(_fh)Niels de Vos-0/+98
The passthrough example filesystem can be used for validating the API and the implementation in the FUSE kernel module.
2018-11-09Don't crash if mountpoint is not specified.Nikolaus Rath-0/+7
Fixes: #319.
2018-10-10passthrough_ll: initialize unused memoryMiklos Szeredi-3/+4
For '.' and '..' entries only the file type in e.attr.st_mode and the inode number in e.attr.st_ino are used. But it's prudent to at least initialize the other fields of struct fuse_entry_param as well, instead of using random values from the stack.
2018-10-10passthrough_ll: allow configuring cachingMiklos Szeredi-8/+55
Caching can be controlled with the following options: "cache=never": disable caching "cache=normal": enable caching but also refresh after the timeout "cache=always": never refresh cache The timeout can be controlled with the "timeout=SEC" option, where SEC is the number of seconds and can be an arbitrary non-negative floating point number.

2018-10-10passthrough_ll: add *xattr() operationsMiklos Szeredi-0/+186
The extended attribute functionality is enabled with the "xattr" option (default) and disabled with the "no_xatt" option. New operations added: - getxattr - listxattr - setxattr - removexattr Caveat: none of these operations will work on a symbolic link, because it's difficult to implement that without races that can result in incorrect operation. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2018-10-10passthrough_ll: add flock()Miklos Szeredi-0/+23
Conditionally enable flock() locking on underlying filesystem, based on the flock/no_flock options. Default is "no_flock", meaning locking will be local to the fuse filesystem and won't be propagated to the filesystem passed through. Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>

2018-10-10passthrough_ll: add source optionVivek Goyal-2/+19
Right now, passthrough_ll will use "/" as source directory for passthrough. We need more flexibility where user can specify path of directory to be passed through. Hence add an option "source=<source-dir>". Signed-off-by: Vivek Goyal <vgoyal@redhat.com> Signed-off-by: Miklos Szeredi <mszeredi@redhat.com>
2018-10-10passthrough_ll: add some of the missing operationsMiklos Szeredi-1/+324
New operations added: - mkdir - mknod - symlink - link - unlink - rmdir - rename - setattr - fsyncdir - flush - fsync - statfs - fallocate Caveats: - The utimes(2) family of syscalls will fail on symlinks on 4.18 and earlier kernels. Hoping to add support to later kernels. - The link(2) and linkat(2) system calls will fail on symlinks unless running with privileges (CAP_DAC_READ_SEARCH).

No functional difference expected, but should still follow the standard. http://pubs.opengroup.org/onlinepubs/009695399/functions/calloc.html
2018-03-28Fix build error on DragonFlyBSD (sync with other *BSD) (#240)Tomohiro Kusumi-1/+1
DragonFlyBSD has no "bsd" in uname, so add 'dragonfly' to conditionals. -- e.g. uname(1) in DragonFlyBSD [root@ ~]# uname DragonFly [root@ ~]# python -c "import sys; print(sys.platform)" dragonfly5

It's just too much pain to keep it working.

The previous name didn't make much sense.
2017-08-24Allow inode cache invalidation in high-level APISławek Rudnicki-2/+296
We re-introduce the functionality of invalidating the caches for an inode specified by path by adding a new routine fuse_invalidate_path. This is useful for network-based file systems which use the high-level API, enabling them to notify the kernel about external changes. This is a revival of Miklos Szeredi's original code for the fuse_invalidate routine.

2017-08-06Added writeback cache to passthrough_llNikolaus Rath-2/+46
This fixes issue #191 (where the test was done by simply adding FUSE_CAP_WRITEBACK_CACHE without adjusting the flags in the open() call). Fixes: #191.
2017-08-06Removed compat stuff in passthrough_llNikolaus Rath-42/+0
As the comment says, this made it compile but not work. If there is a need, we can add these checks to meson.build to only build this file if the prerequisites are satisfied.
