2015-09-11Better handle symlinks with destructive system calls.Henry Stern-29/+42
The unlink, rmdir, and rename system calls behave unexpectedly if you resolve the symbolic link and perform the operation on that instead. It would leave a dangling symlink and delete the original instead which is probably not the intention. This commit adds another parameter to process_path to enable or disable the symlink resolution. The bindfs_unlink, bindfs_rmdir and bindfs_rename functions use this parameter to produce the expected result. rm -rf will still behave differently, deleting the contents of the symlinked directory before removing the symlink and not the linked directory.
2015-09-11Don't resolve broken symbolic links.Henry Stern-4/+9
This commit offers an alternative behaviour of not resolving broken symbolic links in case returning ENOENT is undesirable behaviour.
2015-09-11Add functionality to transparently resolve symbolic links.Henry Stern-82/+247
There exist use cases where you would want bindfs to transparently resolve symbolic links, such as when you are creating a chroot environment with a bound fs. This change adds an option, --resolve-symlinks, that modifies the behaviour of the process_path and bindfs_symlink functions. The process_path function is modified to return a mutable char* that must be freed. When settings.resolve_symlinks is enabled the process_path function calls realpath on the relative path to transparently resolve the symbolic link. A side effect of this change is that broken symbolic links will appear in directory listings but any attempt to access the file of that name will return the ENOENT error code. A subsequent commit offers an alternative behaviour of not resolving broken symbolic links. All callers of process_path are modified to check the return value of process_path to make sure realpath and strdup were successful. They also free the result after use to prevent memory leakage. The bindfs_symlink function is modified to return EPERM when resolve-symlinks is enabled. This must be done to prevent access to arbitrary files on the filesystem.

fuse's pkg-config no longer includes it.
2013-03-01Rename --user/group to --force-user/group.Martin Pärtel-9/+49
The previous names were deprecated as they conflicted with standard mount options. --owner was also deprecated for consistency. The shorthands -u and -g were not deprecated. This fixes issue 25.

Apparently it's not rare.

2012-07-03bindfs: avoid crash due to too-short allocationJan Engelhardt-3/+8
pathconf() can return negative values to indicate an error. Using the result of pathconf naïvely in arithmetic is therefore inappropriate.
2012-07-03bindfs: reduce memory holes in struct permchainJan Engelhardt-2/+2
Reduce holes in struct permchain by appropriately sizing and reordering members.
2012-07-03build: better placement of variablesJan Engelhardt-2/+2
automake options are best set in configure.ac, so they apply not just to the directory, but the whole project. Also move fuse_CFLAGS into AM_CPPFLAGS, because it actually consists of preprocessor directives. (pkgconfig misnamed CFLAGS.)
2012-07-03build: do not change CFLAGSJan Engelhardt-1/+2
CFLAGS must not be touched: it is a user variable. Your previous way of doing it meant that `export CFLAGS="-O1"; ./configure;` never had any effect.
