2021-03-18Fix returning d_ino and d_type by readdir(3) in non-plus modeJean-Pierre André-7/+25
When not using the readdir_plus mode, the d_type was not returned, and the use_ino flag was not used for returning d_ino. This patch fixes the returned values for d_ino and d_type by readdir(3) The test for the returned value of d_ino has been adjusted to also take the d_type into consideration and to check the returned values in both basic readdir and readdir_plus modes. This is done by executing the passthrough test twice. Co-authored-by: Jean-Pierre André <jpandre@users.sourceforge.net>
2021-02-03Fix returning inode numbers from readdir() in offset==0 mode. (#584)Martin Pärtel-1/+66
- Test added for all passthrough examples. - passthrough.c uses offset==0 mode. The others don't. - passthrough.c changed to set FUSE_FILL_DIR_PLUS to make the test pass. - This fixes #583.

2020-01-25Fixes 477, optional src_dir in tst_(rmdir,unlink) (#493)Anthony Rebello-8/+20
tst_rmdir and tst_unlink now pass for passthrough_hp. Previously, tst_rmdir and tst_unlink created the directory / file using src_dir, causing the test to fail as the cache was stale. Now, the src_dir is optional. When cache is enabled, tst_rmdir and tst_unlink do not provide a src_dir, forcing the test to use mnt_dir itself.

2019-08-29Avoid gcc 9.1 strncpy(3) warnings (#447)Stefan Hajnoczi-1/+2
Recent GCC releases have warnings related to common strncpy(3) bugs. These warnings can be avoided by explicitly NUL-terminating the buffer or using memcpy(3) when the intention is to copy just the characters without the NUL terminator. This commit fixes the following warnings: [1/27] Compiling C object 'test/9f86d08@@test_syscalls@exe/test_syscalls.c.o'.

Readdir caching means that direct modifications to the source directory will not be seen immediately, so the test becomes flaky. Fixes: #416.

2018-10-09Add unprivileged option in `mount.fuse3`Mattias Nissler-16/+56
The unprivileged option allows to run the FUSE file system process without privileges by dropping capabilities and preventing them from being re-acquired via setuid / fscaps etc. To accomplish this, mount.fuse sets up the `/dev/fuse` file descriptor and mount itself and passes the file descriptor via the `/dev/fd/%u` mountpoint syntax to the FUSE file system.

2018-07-21Fix readdir() bug when a non-zero offset is specified in filler (#269)Rostislav-0/+61
The bug occurs when a filesystem client reads a directory until the end, seeks using seekdir() to some valid non-zero position and calls readdir(). A valid 'struct dirent *' is expected, but NULL is returned instead. Pseudocode demonstrating the bug: DIR *dp = opendir("some_dir"); struct dirent *de = readdir(dp); /* Get offset of the second entry */ long offset = telldir(dp); /* Read directory until the end */ while (de) de = readdir(de); seekdir(dp, offset); de = readdir(dp); /* de must contain the second entry, but NULL is returned instead */ The reason of the bug is that when the end of directory is reached, the kernel calls FUSE_READDIR op with an offset at the end of directory, so the filesystem's .readdir callback never calls the filler function, and we end up with dh->filled set to 1. After seekdir(), FUSE_READDIR is called again with a new offset, but this time the filesystem's .readdir callback is never called, and an empty reply is returned. Fix by setting dh->filled to 1 only when zero offsets are given to filler function.

Fixes: #224
2018-05-18rename: perform user mode dir loop check when not done in kernelBill Zissimooulos-0/+216
Linux performs the dir loop check (rename(a, a/b/c) or rename(a/b/c, a), etc.) in kernel. Unfortunately other systems do not perform this check (e.g. FreeBSD). This results in a deadlock in get_path2, because libfuse did not expect to handle such cases. We add a check_dir_loop function that performs the dir loop check in user mode and enable it on systems that need it.

2017-08-24Allow inode cache invalidation in high-level APISławek Rudnicki-2/+26
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.
