* libfuse/fuse_daemonize: wait until daemon child process is ready (#55)Hendrik Brueckner2016-06-202-0/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Mounting a FUSE file system remotely using SSH in combination with pseudo-terminal allocation (-t), results in "Transport endpoint is not connected" errors when trying to access the file system contents. For example: # ssh -t root@localhost "cmsfs-fuse /dev/disk/by-path/ccw-0.0.0190 /CMSFS" Connection to localhost closed. # ls /CMSFS ls: cannot access '/CMSFS': Transport endpoint is not connected The cmsfs-fuse main program (which can also be any other FUSE file system) calls into the fuse_main() libfuse library function. The fuse_main() function later calls fuse_daemonize() to fork the daemon process to handle the FUSE file system I/O. The fuse_daemonize() function calls fork() as usual. The child proceeds with setsid() and then redirecting its file descriptors to /dev/null etc. The parent process, simply exits. The child's functions and the parent's exit creates a subtle race. This is seen with an SSH connection. The SSH command above calls cmsfs-fuse on an allocated pseudo-terminal device (-t option). If the parent exits, SSH receives the command completion and closes the connection, that means, it closes the master side of the pseudo-terminal. This causes a HUP signal being sent to the process group on the pseudo-terminal. At this point in time, the child might not have completed the setsid() call and, hence, becomes terminated. Note that fuse daemon sets up its signal handlers after fuse_daemonize() has completed. Even if the child has the chance to disassociate from its parent process group to become it's own process group with setsid(), the child still has the pseudo-terminal opened as stdin, stdout, and stderr. So the pseudo-terminal still behave as controlling terminal and might cause a SIGHUP at closing the the master side. To solve the problem, the parent has to wait until the child (the fuse daemon process) has completed its processing, that means, has become its own process group with setsid() and closed any file descriptors pointing to the pseudo-terminal.

* libfuse: pass security context options to kernelDalvik Khertel2016-06-202-0/+9
| | | | | | | | | | | Mount can be used with an "-o context=" option in order to specify a mountpoint-wide SELinux security context different from the default context provided by the active SELinux policy. This is useful in order to enable users to mount multiple sshfs targets under distinct contexts, which is my main motivation for getting this patch mainlined. Closes: #36

* Changed Changelog formatNikolaus Rath2016-01-141-38/+24
| | | | | | | | | Up to now, the Changelog has essentially been a (manually maintained) copy of the git commit history. This doesn't seem to have any point other than following the GNU coding standards. I believe it's much better to use the Changelog to summarize the release-to-release changes that are most important for users, so this is what we'll do from now on.
* Removed placeholder README file and switch automake to foreign flavor.Nikolaus Rath2016-01-142-4/+1
| | | | | | The GNU flavor merely requires to existence of some files (including README, but we prefer README.md), so there seems to be little point in using it.
* Removed hopelessly outdated files.Nikolaus Rath2016-01-143-427/+1

* Enable subdir-objects automake optionNikolaus Rath2016-01-142-0/+2
| | | | This is recommended for forward-compatibility.
* Update makeconf.shNikolaus Rath2016-01-141-26/+7
| | | | | | | | | Describe why manual copying of config.rpath is necessary, and fail with a more helpful message if it can't be found. Remove code for systems without autoreconf - it's apparently not used by anyone since it has been broken for quite some time (there is no `kernel` directory anymore).

| | | | | | | Running "svn update" on a fuse filesystem could deadlock because of a bug in the way the paths are locked. Reported by Kazuaki Anami
* Fix missing config.h in buffer.cMiklos Szeredi2012-08-244-0/+7
| | | | | | | | | | | | | 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. Reported by Matthew Gabeler-Lee
* Zero out node when allocating from a slab.Miklos Szeredi2012-08-141-10/+4

* Fix "fuse internal error: node NNN not found"Miklos Szeredi2012-08-142-4/+20
| | | | | | | | | | Commit 4dc7e675bb (Don't unhash name in FORGET) broke the forget logic in a subtle way, resulting in "fuse internal error: node NNN not found" and causing the filesystem daemon to abort. Fix by incrementing the node refcount if nlookup goes from zero to one. Reported by Kyle Lippincott

| | | | | | | | The failure path of try_get_path2() erronously tried to free the "path1" value (an address on the stack) instead of the allocated string pointed to by "path1". This caused the library to crash. Reported by Itay Perl
