* Fix FUSE_CANONICAL_PATH responseZim2020-03-251-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bluecross kernel introduced a change, 4fb542f2aa1414cea5686efcf72a411b7213c375 that breaks responses to canonical paths. The patch above tried to guarantee that the canonical path returned from the FUSE daemon is null terminated. It does this by replacing the last character in the path returned from the FUSE daemon with '\0'. Since the size of the response returned from the FUSE daemon is gotten from strlen which doesn't take into account the null terminating character. This means that the kernel fix above will break the file path returned from userspace. Effectively replacing /storage/emulated/0 with /storage/emulated/. It is unclear how this breaks inotify on the root path but not inotify on Download/ for instance since that too is replaced by /storage/emulated/Downloa. One thing I've noticed is that in the case of Download, being replaced with Downloa, there is an error generated, since Downloa doesn't exist, but in the case of /storage/emulated/0, there is no error since /storage/emulated/ exists. In any case, this cl returns a buffer size including the '\0' to the kernel and seems right given that the actual size of the buffer returned to the kernel is now correct.

| * Support FUSE_CANONICAL_PATH in libfuseZim2020-01-105-0/+156
| | | | | | | | | | | | | | | | | | | | | | FUSE_CANONICAL_PATH opcode, (2016) was added in some Android kernels to support inotify. Add canonical path handlers in libfuse and create a patch file to easily apply this patch on top of updates.

But that causes two problems for file systems that aren't interruptible: 1) A process may block on a signal, even if another thread could've handled the signal. The kernel must know whether the FUSE thread is interruptible before deciding which thread should receive a signal. 2) The protocol allows a FUSE daemon to simply ignore FUSE_INTERRUPT operations. From the kernel's point of view, that is indistinguishable from a FUSE_INTERRUPT operation arriving after the original operation had already completed. Thus, the kernel can't interpret an ignored FUSE_INTERRUPT as an indication that the daemon is non-interruptible. With the -o nointr mount option, no FUSE_INTERRUPT operations will ever be sent. Most FUSE file systems should require no modifications to take advantage of this mount option.
| | | | * passthrough_ll: drop lo_dirp->fd field (#464)Stefan Hajnoczi2019-11-031-7/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | fdopendir(3) takes ownership of the file descriptor. The presence of the lo_dirp->fd field could lead to someone incorrectly adding a close(d->fd) cleanup call in the future. Do not store the file descriptor in struct lo_dirp since it is unused.

| | | | * Introduce callback for loggingStefan Hajnoczi2019-09-0418-175/+303

This allows libfuse applications to send messages to syslog(3) or other logging systems. See include/fuse_log.h for details. Convert libfuse from fprintf(stderr, ...) to log_fuse(level, ...). Most messages are error messages with FUSE_LOG_ERR log level. There are also some debug messages which now use the FUSE_LOG_DEBUG log level. Note that lib/mount_util.c is used by both libfuse and fusermount3. Since fusermount3 does not link against libfuse, we cannot call fuse_log() from lib/mount_util.c. This file will continue to use fprintf(stderr, ...) until someone figures out how to split it up. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
