2022-12-29main: doMount: call Setsid before starting loggerJakob Unterwurzacher
The logger should be in the new background session together with the gocryptfs process. Before: $ xfce4-terminal -x gocryptfs a b $ ps xao pid,ppid,pgid,sid,comm,args PID PPID PGID SID COMMAND COMMAND 192272 1371 192272 192272 gocryptfs /ssd2/jakob.donotbackup/go/bin/gocryptfs -fg -notifypid=192265 a b 192292 192272 192265 192265 logge <defunct> [logger] <defunct> After: $ xfce4-terminal -x gocryptfs a b $ ps xao pid,ppid,pgid,sid,comm,args PID PPID PGID SID COMMAND COMMAND 211714 1371 211714 211714 gocryptfs /ssd2/jakob.donotbackup/go/bin/gocryptfs -fg -notifypid=211708 a b 211776 211714 211714 211714 logger logger -t gocryptfs-211714-logger Fixes https://github.com/rfjakob/gocryptfs/issues/660
2021-10-21cli: add -longnamemaxJakob Unterwurzacher
Fixes https://github.com/rfjakob/gocryptfs/issues/499
2021-10-21nametransform: add longNameMax parameterJakob Unterwurzacher
Determines when to start hashing long names instead of hardcoded 255. Will be used to alleviate "name too long" issues some users see on cloud storage. https://github.com/rfjakob/gocryptfs/issues/499
2021-09-10cli: drop -forcedecode flagJakob Unterwurzacher
The rewritten openssl backend does not support this flag anymore, and it was inherently dangerour. Drop it (ignored for compatibility)
2021-09-08Make -openssl also apply to xchachaJakob Unterwurzacher
Now that stupidgcm supports xchacha, make it available on mount.
2021-08-30Unbreak hyperlinks broken by go mod v2 conversionJakob Unterwurzacher
Commit 69d88505fd7f4cb0d9e4f1918de296342fe05858 go mod: declare module version v2 translated all instances of "github.com/rfjakob/gocryptfs/" to "github.com/rfjakob/gocryptfs/v2/". Unfortunately, this included hyperlinks. Unbreak the hyperlinks like this: find . -name \*.go | xargs sed -i s%https://github.com/rfjakob/gocryptfs/v2/%https://github.com/rfjakob/gocryptfs/v2/%
2021-08-30Reimplement -serialize_reads flag using new SyncRead mount flagJakob Unterwurzacher
Let the kernel do the work for us. See https://github.com/hanwen/go-fuse/commit/15a8bb029a4e1a51e10043c370970596b1fbb737 for more info.
2021-08-23cryptocore: add NonceSize to AEADTypeEnumJakob Unterwurzacher
Have the information in one centralized place, and access it from main as needed.
2021-08-23Add partial XChaCha20-Poly1305 support (mount flag only)Jakob Unterwurzacher
Mount flag only at the moment, not saved to gocryptfs.conf. https://github.com/rfjakob/gocryptfs/issues/452
2021-08-23go mod: declare module version v2Jakob Unterwurzacher
Our git version is v2+ for some time now, but go.mod still declared v1. Hopefully making both match makes https://pkg.go.dev/github.com/rfjakob/gocryptfs/v2 work. All the import paths have been fixed like this: find . -name \*.go | xargs sed -i s%github.com/rfjakob/gocryptfs/%github.com/rfjakob/gocryptfs/v2/%
2021-08-20-deterministic-names: accept flag on -initJakob Unterwurzacher
And store it in gocryptfs.conf (=remove DirIV feature flag).
2021-08-20Implement -deterministic-names: extended -zerodirivJakob Unterwurzacher
-deterministc-names uses all-zero dirivs but does not write them to disk anymore.

2021-08-19golangci-lint: fix issues found by gosimpleJakob Unterwurzacher
Everything except the if err2.Err == syscall.EOPNOTSUPP case. Gets too confusing when collapsed into a single line.

The startup debug output was very verbose but still missing some effective crypto settings.

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
2021-01-02-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
2020-12-20main: add "-kernel_cache" flaggmd20

2020-10-18fusefronted: reject GETXATTR "security.capability"Jakob Unterwurzacher
Unless we are mounted with -suid, we can reject these requests, and gain back some lost speed. Closes https://github.com/rfjakob/gocryptfs/issues/515
2020-10-14main: show microseconds in go-fuse logsJakob Unterwurzacher
Suppress the date but show microseconds in fuse debug logs (-fusedebug) and go-fuse warnings.
2020-07-27v2api: pass fusedebug option via MountOptionsJakob Unterwurzacher
srv.SetDebug() is deprecated and only enables the debug output after the init sequence, so we missed the first few transaction in the debug output.
2020-07-19v2api: fsck: use a temporary mountJakob Unterwurzacher
Directly accessing the Nodes does not work properly, as there is no way to attach a newly LOOKUPped Node to the tree. This means Path() does not work. Use an actual mount instead and walk the tree.

2020-05-17Update go-fuse import path to github.com/hanwen/go-fuse/v2Jakob Unterwurzacher
We need https://github.com/hanwen/go-fuse/commit/fd7328faf9fdf75709f7ba7df7072aaf4eeb18b3 to fix a crash reported in https://github.com/rfjakob/gocryptfs/issues/430 : 2019/10/30 17:14:16 Unknown opcode 2016 panic: runtime error: invalid memory address or nil pointer dereference [signal SIGSEGV: segmentation violation code=0x1 addr=0x20 pc=0x508d38] This patch is only in the v2.x.x branch. Upgrade to v2, as the old API is also supported there. Running git grep hanwen/go-fuse | grep -v hanwen/go-fuse/v2 to check for forgotten references comes back clean.

2020-01-14main: haveFusermount2: respect PATH environment variableJakob Unterwurzacher
Use exec.LookPath() to find fusermount in the user's PATH first. Fall back to /bin/fusermount for the case that PATH is not set, like go-fuse does. Fixes https://github.com/rfjakob/gocryptfs/issues/448
2019-12-28main: detect fusermount3 and don't add `nonempty`Jakob Unterwurzacher
fusermount3 (i.e. fusermount from libfuse 3.x) has dropped the `nonempty` option. Detect fusermount3 and don't add `nonempty` in this case. Fixes https://github.com/rfjakob/gocryptfs/pull/440

Preallocation on Btrfs is broken ( https://github.com/rfjakob/gocryptfs/issues/395 , https://lore.kernel.org/linux-btrfs/CAPv9Zmk46As_P9Gyf_icET53xRda63h7iC1meES9xbdDEt9qow@mail.gmail.com/ ) and slow ( https://github.com/rfjakob/gocryptfs/issues/63 ).
2019-03-26reverse mode: support wildcard exclude (--exclude-wildcard)Eduardo M KALINOWSKI
This adds support for gitignore-like wildcards and exclude patters in reverse mode. It (somewhat) fixes #273: no regexp support, but the syntax should be powerful enough to satisfy most needs. Also, since adding a lot of --exclude options can be tedious, it adds the --exclude-from option to read patterns from a file (or files).

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
2018-09-18main: sanitize commas from fsnameJakob Unterwurzacher
The cipherdir path is used as the fsname, as displayed in "df -T". Now, having a comma in fsname triggers a sanity check in go-fuse, aborting the mount with: /bin/fusermount: mount failed: Invalid argument fuse.NewServer failed: fusermount exited with code 256 Sanitize fsname by replacing any commas with underscores. https://github.com/rfjakob/gocryptfs/issues/262
