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/%
xfstests generic/523 discovered that we allowed to set
xattrs with "/" in the name, but did not allow to read
them later.
With this change we do not allow to set them in the first
place.
We need
fd7328faf9
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.
CheckTrailingGarbage was called even when "-passfile" was
used, which is stupid, and causes false positives:
https://github.com/rfjakob/gocryptfs/issues/391
(false error "Received trailing garbage after the password"
when using -passfile in .bash_profile)
Instead of trying to improve the logic to handle that case
and make everything even more complicated, delete the function.
It is unclear if actually helps in some cases, and it definitely
harms as shown by the above bug report.
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).
Go version go1.10.7 linux/amd64 complains with:
internal/fusefrontend_reverse/rfs.go:333: declaration of "entries" shadows
declaration at internal/fusefrontend_reverse/rfs.go:327
Fixes https://github.com/rfjakob/gocryptfs/issues/286 :
While the actual file is properly excluded, the * .name file is still leaked in the directory listing:
```

Excluded files showed up in directory listing like this:

The function used to do two things:
1) Walk the directory tree in a manner safe from symlink attacks
2) Open the final component in the mode requested by the caller
This change drops (2), which was only used once, and lets the caller
handle it. This simplifies the function and makes it fit for reuse in
forward mode in openBackingPath(), and for using O_PATH on Linux.
Both fusefrontend and fusefrontend_reverse were doing
essentially the same thing, move it into main's
initFuseFrontend.
A side-effect is that we have a reference to cryptocore
in main, which will help with wiping the keys on exit
(https://github.com/rfjakob/gocryptfs/issues/211).
