2020-12-27util/fusermount.c: Assume the kernel supports UMOUNT_NOFOLLOW (#574)Sargun Dhillon-23/+1
UMOUNT_NOFOLLOW was added in Kernel 2.6.34. It's been 10 years since it's been added Kernel 5.9, and 5.10 break this check mechanism[1]. Let's deprecate it. [1]: https://lore.kernel.org/linux-fsdevel/20201223102604.2078-1-sargun@sargun.me/ Signed-off-by: Sargun Dhillon <sargun@sargun.me>

In commit d614415a ("buffer.c: check whether buf is NULL in fuse_bufvec_advance func"), if fuse_bufvec_current func returns NULL, it returns 1 directly. Actually, we should return 0 when buf is NULL.

2020-09-20Allow caching symlinks in kernel page cache. (#551)Etienne Dublé-1/+20
This commit defines a new capability called `FUSE_CAP_CACHE_SYMLINKS`. It is off by default but you can now enable it by setting this flag in in the `want` field of the `fuse_conn_info` structure. When enabled, the kernel will save symlinks in its page cache, by making use of the feature introduced in kernel 4.20: https://github.com/torvalds/linux/commit/5571f1e65486be025f73fa6aa30fb03725d362a2

2020-07-10Fix: crash on failure to set locale (#529)Jérémie Galarneau-4/+9
setlocale() can fail, returning NULL, if the user has an invalid (or missing) locale set in the LANG environment variable. In my case, this happens when using VS Code's integrated terminal to launch a fuse-based filesystem. A bug (fix upcoming) results in VS Code setting an invalid locale. iconv_help() currently passes the return value of setlocale(...) directly to strdup() without checking if it is NULL, resulting in a crash. To reproduce, simply set LANG="something_invalid" and call fuse_lib_help(). Stack trace when the process receives `SIGSEGV`: (gdb) bt #0 0x00007fabd0fcc4b5 in __strlen_avx2 () from /usr/lib/libc.so.6 #1 0x00007fabd0ef9233 in strdup () from /usr/lib/libc.so.6 #2 0x00007fabd13b8128 in iconv_help () at ../lib/modules/iconv.c:641 #3 0x00007fabd13b81a8 in iconv_opt_proc (data=0x55580a6ee850, arg=0x55580a6edfb0 "-h", key=0, outargs=0x7ffeeb1a8ec8) at ../lib/modules/iconv.c:658 #4 0x00007fabd13af7d5 in call_proc (ctx=0x7ffeeb1a8ea0, arg=0x55580a6edfb0 "-h", key=0, iso=0) at ../lib/fuse_opt.c:161 #5 0x00007fabd13afaf1 in process_opt (ctx=0x7ffeeb1a8ea0, opt=0x7fabd13c3d40 <iconv_opts>, sep=0, arg=0x55580a6edfb0 "-h", iso=0) at ../lib/fuse_opt.c:233 #6 0x00007fabd13afd5a in process_gopt (ctx=0x7ffeeb1a8ea0, arg=0x55580a6edfb0 "-h", iso=0) at ../lib/fuse_opt.c:285 #7 0x00007fabd13b0117 in process_one (ctx=0x7ffeeb1a8ea0, arg=0x55580a6edfb0 "-h") at ../lib/fuse_opt.c:368 #8 0x00007fabd13b0190 in opt_parse (ctx=0x7ffeeb1a8ea0) at ../lib/fuse_opt.c:379 #9 0x00007fabd13b03d3 in fuse_opt_parse (args=0x7ffeeb1a8f70, data=0x55580a6ee850, opts=0x7fabd13c3d40 <iconv_opts>, proc=0x7fabd13b8186 <iconv_opt_proc>) at ../lib/fuse_opt.c:414 #10 0x00007fabd13b8226 in iconv_new (args=0x7ffeeb1a8f70, next=0x0) at ../lib/modules/iconv.c:680 #11 0x00007fabd13a5627 in print_module_help (name=0x7fabd13b9e1c "iconv", fac=0x7fabd13d48e0 <fuse_module_iconv_factory>) at ../lib/fuse.c:4692 #12 0x00007fabd13a56aa in fuse_lib_help (args=0x7ffeeb1a9238) at ../lib/fuse.c:4721 iconv_help() is modified to print an error when setlocale() fails.

2020-05-14passthrough_ll: remove symlink fallbacks (#514)Miklos Szeredi-139/+14
* passthrough_ll/hp: remove symlink fallbacks Path lookup in the kernel has special rules for looking up magic symlinks under /proc. If a filesystem operation is instructed to follow symlinks (e.g. via AT_SYMLINK_FOLLOW or lack of AT_SYMLINK_NOFOLLOW), and the final component is such a proc symlink, then the target of the magic symlink is used for the operation, even if the target itself is a symlink. I.e. path lookup is always terminated after following a final magic symlink. I was erronously assuming that in the above case the target symlink would also be followed, and so workarounds were added for a couple of operations to handle the symlink case. Since the symlink can be handled simply by following the proc symlink, these workardouds are not needed.

2020-03-13Fix issue preventing using splice with reads (#505)Jean-Yves VET-8/+6
Context: SPLICE_WRITE is not used with regular buffers (i.e. when they are not file-descriptor backed buffers). There is a bug which assumes file descriptors are used. If the amount of data associated with those FD is lower than twice the page size, SPLICE_WRITE is not utilized. With regular buffers the aggregated size was always 0. Because vmsplice (splice user pages to/from a pipe) is called before splice in fuse_lowlevel.c, regular buffers would also work with splice. This patch prevents to fallback to non-splice enabled copies when itheir is no FD involved.
