2021-05-15Add -acl flag to enable ACL enforcementJakob Unterwurzacher
With test to verify that it actually works this time: Run "make root_test". Depends-on: https://github.com/rfjakob/gocryptfs/issues/536 Fixes: https://github.com/rfjakob/gocryptfs/issues/536
2021-05-15fusefrontend: fix RENAME_NOREPLACE darwin build failureJakob Unterwurzacher
Error was: internal/fusefrontend/node.go:371:2: duplicate case syscallcompat.RENAME_NOREPLACE (value 0) in switch previous case at internal/fusefrontend/node.go:368:7 Rewrite using "if"s instead.
2021-05-08fusefrontend: avoid duplicate const definitionJakob Unterwurzacher
RENAME_NOREPLACE is already defined in syscallcompat.
2021-05-08fusefrontend: reject broken RENAME_EXCHANGE and RENAME_WHITEOUTJakob Unterwurzacher
Discovered by xfstests generic/013: or implementation for RENAME_EXCHANGE and RENAME_WHITEOUT is incomplete. Reject the flags so that the caller retries with regular rename.

2021-04-07Doc: update performance.txtJakob Unterwurzacher
2021-04-07fusefrontend: make dirCache work for "node itself"Jakob Unterwurzacher
"node itself" can be converted to node + child by ascending one level. Performance gains are spectacular, as will be seen in the next commit.
2021-04-05profiling/ls.bash: add -nosyslogJakob Unterwurzacher
This makes sure we actually see the dirCache stats.
2021-04-05fusefrontend: print dirCache stats after unmountJakob Unterwurzacher
2021-04-04fs: more idiomatic dirCache struct namingJakob Unterwurzacher
2021-04-03performance.txt: add dirfd caching resultsJakob Unterwurzacher
Also, add v2.0-beta2-16-geaca820. I bisected the ls performance regression to this commit.
2021-04-03fs: add initial dirfd cachingJakob Unterwurzacher
dirfd caching was temporarily removed when moving to the v2api. Add it back to gain back some lost speed.
2021-04-03tests: fusefronted: fix TestOpenBackingDirJakob Unterwurzacher
This test only worked accidentially, and would break once dirfd caching is added. fs.Mkdir(..., "dir1/dir2", ...) is illegal (child name cannot contain slashes).
2021-04-03fusefronted: replace last rn.openBackingDir() callsJakob Unterwurzacher
Use the n.prepareAtSyscall() wrapper instead. Prepares for adding caching into n.prepareAtSyscall().
2021-04-02tests: sharedstorage: wait 100ms longer for cache expiryJakob Unterwurzacher
With 1.0 seconds we see failures on Travis, example: https://travis-ci.org/github/rfjakob/gocryptfs/builds/765648739 With 1.1 seconds it seems to always work.
2021-03-30profiling: add ls.bashJakob Unterwurzacher
2021-03-30go.mod: temporarily switch to go-fuse forkJakob Unterwurzacher

I only use package-static.bash nowadays.
2021-03-26README: fix compile instructions for Go 1.13+Jakob Unterwurzacher
"go get -d" does not download to GOPATH/src anymore: https://github.com/golang/go/issues/31529 Use explicit "git clone" to the current directory as suggested in https://github.com/golang/go/issues/31529#issuecomment-484920157 . Fixes https://github.com/rfjakob/gocryptfs/issues/553

Towards better test coverage of shared backing storage mounts. https://github.com/rfjakob/gocryptfs/issues/525
2021-03-21test_helpers: VerifySize: don't complain about ino mismatchJakob Unterwurzacher
The inode number is not stable with `-sharedstorage`. Ignore it. Failure was like this: --- FAIL: TestFallocate (0.02s) helpers.go:229: Stat vs Fstat mismatch: st= {59 11543 1 33188 1026 1026 0 0 0 4096 8 {1616315569 838232716} {1616315569 838232716} {1616315569 838232716} [0 0 0]} st2={59 11545 1 33188 1026 1026 0 0 0 4096 8 {1616315569 838232716} {1616315569 838232716} {1616315569 838232716} [0 0 0]}
2021-03-21fusefronted: move Create() and Open() to new fileJakob Unterwurzacher
And deduplicate the code a little.
2021-03-21fusefrontend: -sharedstorage: fix TestRmwRace failureJakob Unterwurzacher
The Open() and Create() paths used different inode numbers, which broke openfiletable locking against concurred readers.

2021-03-20tests: MountOrFatal creates mnt dir itselfJakob Unterwurzacher
Allows to drop a few Mkdir()s.
2021-03-14syscallcompat: getdents: link to #483Jakob Unterwurzacher
Give a user receiving the Getdents warning some background info.
2021-03-12tests: add TestDiskFullJakob Unterwurzacher
Also fix incomplete uid restoration in TestSupplementaryGroups and replace syscall.Setregid and friends with unix.Setregid and friends. This test is added to check if have problems handling a full disk. The ticket https://github.com/rfjakob/gocryptfs/issues/550 states that the full disk was not where the backing gocryptfs filesystem was, but this has no effect on gocryptfs, so we test the harder case.
2021-03-12Makefile: root_test: don't run test when compile failsJakob Unterwurzacher
2021-03-07v2api: -sharestorage: disable hard link tracking & add testsJakob Unterwurzacher
Hard link tracking was not correctly disabled since the migration to the go-fuse v2 api. Add a test to ensure it stays off. Fixes https://github.com/rfjakob/gocryptfs/issues/525
2021-02-07fusefrontend: do not encrypt ACLsJakob Unterwurzacher
Pass through system.posix_acl_access and system.posix_acl_default unencrypted to fix "cp -a" problems. "cp -a" uses "setxattr" even to set normal permissions, see https://www.spinics.net/lists/linux-nfs/msg63986.html . Fixes https://github.com/rfjakob/gocryptfs/issues/543
2021-02-07tests/xattr: fix acl blobJakob Unterwurzacher
The blob was truncated to 31 bytes.

2021-02-06syscallcompat: MknodatUser: work around changed syscall.Setgroups semanticsJakob Unterwurzacher
Since go1.16beta1 (commit d1b1145cace8b968307f9311ff611e4bb810710c , https://go-review.googlesource.com/c/go/+/210639 ) syscall.{Setgroups,Setregid,Setreuid} affects all threads, which is exactly what we not want. We now use unix.{Setgroups,Setregid,Setreuid} instead. Workarounds https://github.com/golang/go/issues/1435 .
2021-01-31README: note Trezor removalJakob Unterwurzacher
Adding support for Trezor was listed, but removal was not, causing confusion. Closes https://github.com/rfjakob/gocryptfs/pull/534
2021-01-31go.mod: update go-fuse to latest masterJakob Unterwurzacher
We need https://github.com/hanwen/go-fuse/commit/09a3c381714cf1011fb2d08885f29896cd496a0c fuse: support the new macFUSE mount protocol so mounting on MacFuse 4.x works. Updated using go get github.com/hanwen/go-fuse/v2@master . Fixes https://github.com/rfjakob/gocryptfs/issues/524
2021-01-10nametransform: make `gocryptfs.diriv` and `gocryptfs.xxx.name` files ↵Jakob Unterwurzacher
world-readable Make `gocryptfs.diriv` and `gocryptfs.xxx.name` files world-readable to make encrypted backups easier when mounting via fstab. Having the files follow chmod/chown of their parent does not seem to be worth the hassle. The content of the diriv files is not secret, and both diriv and name files are protected by the perms of the parent dir. Fixes https://github.com/rfjakob/gocryptfs/issues/539
2021-01-10MANPAGE: add sub-headers to EXAMPLESJakob Unterwurzacher

2021-01-02-idle: don't lazy-unmountJakob Unterwurzacher
When a process has its working dir inside the mount, the only way we notice is that we get EBUSY when trying to unmount. We used to lazy-unmount in this case, but this means pulling the rug from under the process. For example, bash will start throwing cd: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory messages. Fixes https://github.com/rfjakob/gocryptfs/issues/533
