gocryptfs/internal/syscallcompat, branch v2.0Mirror of gocryptfs source code on Githubhttp://nuetzlich.net/cgit/gocryptfs/atom?h=v2.02021-06-02T17:10:36+00:00fusefrontend: run acl Setxattr in user context2021-06-02T17:10:36+00:00Jakob Unterwurzacher2021-06-02T17:10:36+00:00urn:sha1:a38e5988bae3319a2c1c6745064f5785a0971d05
The result of setting an acl depends on who runs the
operation!
Fixes fuse-xfstests generic/375

syscallcompat: add GetdentsSpecial()2021-05-26T11:17:56+00:00Jakob Unterwurzacher2021-05-23T10:00:09+00:00urn:sha1:1b3c3b1347ef711ec38bb4c5cb14661035faf2ce
GetdentsSpecial calls then Getdents syscall,
with normal entries and "." / ".." split into two slices.
syscallcompat: also refactor MkdiratUser on GOOS=darwin2021-05-22T20:01:46+00:00Jakob Unterwurzacher2021-05-22T20:01:46+00:00urn:sha1:09870bfac51995a0a8875137ed9e6d60688240f1
Breakage was:
+GOOS=darwin
+GOARCH=amd64
+go build -tags without_openssl
internal/fusefrontend/node_dir_ops.go:45:34: cannot use context (type *fuse.Context) as type *fuse.Caller in argument to syscallcompat.MkdiratUser

syscallcompat: refactor MkdiratUser to take fuse.Context2021-05-22T19:44:19+00:00Jakob Unterwurzacher2021-05-22T19:44:19+00:00urn:sha1:e1853e10116e97d7dcce895d6603dae1379a37b7
Let's have MkdiratUser take fuse.Context like everybody
else.
syscallcompat: deduplicate OpenatUser/MknodatUser/SymlinkatUser/MkdiratUser2021-05-22T19:39:29+00:00Jakob Unterwurzacher2021-05-22T19:37:41+00:00urn:sha1:cb4f9f9e2934400fa0abf9bd6c65455783b2768e
Turns out the whole euid switching logic can be shared when
wrapping the syscall in a closure.
syscallcompat: getdents: link to #4832021-03-14T13:43:11+00:00Jakob Unterwurzacher2021-03-14T13:43:11+00:00urn:sha1:f6036c429a35dff83bd01b3e867262cf7e8468ef
Give a user receiving the Getdents warning some background info.
syscallcompat: MknodatUser: work around changed syscall.Setgroups semantics2021-02-06T10:38:25+00:00Jakob Unterwurzacher2021-02-06T10:13:22+00:00urn:sha1:80a651a19474c78b1b2716cbf8c85ffd78698823
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.

fusefronted: reject GETXATTR "security.capability"2020-10-18T19:07:30+00:00Jakob Unterwurzacher2020-10-18T19:05:44+00:00urn:sha1:6697ffd6e213828ff4cd873cd1d104877096a230
Unless we are mounted with -suid, we can reject
these requests, and gain back some lost speed.
