2019-01-02fusefrontend: openBackingDir: fix fd leak in error pathJakob Unterwurzacher
Reported by @slackner at https://github.com/rfjakob/gocryptfs/commit/932efbd4593fe6be6c86f0dafeaea32910b7c246#r31813373 thanks!
2019-01-01fusefrontend: only compile getBackingPath() on DarwinJakob Unterwurzacher
This function is NOT symlink-safe. Darwin needs it because it lacks fgetxattr(2) and friends.
2019-01-01fusefrontend: make GetXAttr() symlink-safe on LinuxJakob Unterwurzacher
Uses the /proc/self/fd trick, which does not work on Darwin.
2019-01-01fusefrontend: mark a few more functions as symlink-safe / unsafeJakob Unterwurzacher
2019-01-01fusefrontend: make openBackingDir() symlink-safeJakob Unterwurzacher
openBackingDir() used encryptPath(), which is not symlink-safe itself. Drop encryptPath() and implement our own directory walk. Adds three seconds to untar and two seconds to rm: $ ./benchmark.bash Testing gocryptfs at /tmp/benchmark.bash.MzG: gocryptfs v1.6-36-g8fb3c2f-dirty; go-fuse v20170619-66-g6df8ddc; 2018-10-14 go1.11 WRITE: 262144000 bytes (262 MB, 250 MiB) copied, 1.25078 s, 210 MB/s READ: 262144000 bytes (262 MB, 250 MiB) copied, 1.0318 s, 254 MB/s UNTAR: 20.941 MD5: 11.568 LS: 1.638 RM: 5.337
2018-10-11Add option for autounmountJesse Dunietz
Even though filesystem notifications aren't implemented for FUSE, I decided to try my hand at implementing the autounmount feature (#128). I based it on the EncFS autounmount code, which records filesystem accesses and checks every X seconds whether it's idled long enough to unmount. I've tested the feature locally, but I haven't added any tests for this flag. I also haven't worked with Go before. So please let me know if there's anything that should be done differently. One particular concern: I worked from the assumption that the open files table is unique per-filesystem. If that's not true, I'll need to add an open file count and associated lock to the Filesystem type instead. https://github.com/rfjakob/gocryptfs/pull/265
2018-09-23fusefrontend: add named parameters to openBackingDirJakob Unterwurzacher
Named parameters make using the function easier.
2018-09-23fusefrontend: get rid of os.File* wrappingJakob Unterwurzacher
Directly use int file descriptors for the dirfd and get rid of one level of indirection.
2018-09-08fusefrontend: use OpenDirNofollow in openBackingDirJakob Unterwurzacher
Rename openBackingPath to openBackingDir and use OpenDirNofollow to be safe against symlink races. Note that openBackingDir is not used in several important code paths like Create(). But it is used in Unlink, and the performance impact in the RM benchmark to be acceptable: Before $ ./benchmark.bash Testing gocryptfs at /tmp/benchmark.bash.bYO: gocryptfs v1.6-12-g930c37e-dirty; go-fuse v20170619-49-gb11e293; 2018-09-08 go1.10.3 WRITE: 262144000 bytes (262 MB, 250 MiB) copied, 1.07979 s, 243 MB/s READ: 262144000 bytes (262 MB, 250 MiB) copied, 0.882413 s, 297 MB/s UNTAR: 16.703 MD5: 7.606 LS: 1.349 RM: 3.237 After $ ./benchmark.bash Testing gocryptfs at /tmp/benchmark.bash.jK3: gocryptfs v1.6-13-g84d6faf-dirty; go-fuse v20170619-49-gb11e293; 2018-09-08 go1.10.3 WRITE: 262144000 bytes (262 MB, 250 MiB) copied, 1.06261 s, 247 MB/s READ: 262144000 bytes (262 MB, 250 MiB) copied, 0.947228 s, 277 MB/s UNTAR: 17.197 MD5: 7.540 LS: 1.364 RM: 3.410
