2020-07-12v2api: properly implement Node.SetattrJakob Unterwurzacher
We used to always open a *File2 and letting the *File2 handle Setattr. This does not work it we cannot open the file!

2020-07-12v2api: Getattr: fix file sizeJakob Unterwurzacher
2020-07-12v2api: call InitSerializerJakob Unterwurzacher
If we don't, reads hang with -serialize_reads.
2020-07-12v2api: fix Rename trying to overwrite itselfJakob Unterwurzacher
We used to do this [pid 99182] renameat2(14, "Y_4DAxKvj1QnXmJx2AkrKA", 15, ".", RENAME_NOREPLACE <unfinished ...> which was not the intention.
2020-07-12v2api: fix Mkdir crash when using plaintextnamesJakob Unterwurzacher

2020-07-11v2api: implement RenameJakob Unterwurzacher
2020-07-11v2api: remove OpenatUserCtx, MknodatUserCtx helpersJakob Unterwurzacher
Instead, use the new toFuseCtx() function introduced in an earlier commit.

2020-06-21v2api: implement GetAttr and ReaddirJakob Unterwurzacher
2020-06-21v2api: implement Lookup()Jakob Unterwurzacher
Compiles, but untested otherwise. No caching.
2020-06-21inomap: clarify TranslateStat function commentJakob Unterwurzacher
Also, fix the namespaceMap comment.
2020-06-21v2api (go-fuse v2 api): initial noop implementationJakob Unterwurzacher
Compiles and mounts but does nothing useful.
2020-06-06badname: stop trying to decrypt at length 22Jakob Unterwurzacher
At least 16 bytes due to AES --> at least 22 characters in base64
2020-06-06Added auto decryption of invalid file namesDerDonut
Changed invalid file decoding and decryption. Function DecryptName now shortens the filename until the filename is decodable and decryptable. Will work with valid **and** invalid Base64URL delimiter (valid delimiter [0-9a-zA-z_\\-]. If the filename is not decryptable at all, it returns the original cipher name with flag suffix Changed cli tests to generate decryptable and undecryptable file names with correct encrypted content. Replacing #474, extends #393
2020-05-24Revert "fusefrontend: don't always clear the dircache in Rename"Jakob Unterwurzacher
As noticed by @slackner in https://github.com/rfjakob/gocryptfs/commit/cb8872577d66ff0fc38bcd70493be06bc0f34ffa#commitcomment-39405233 , this is not safe. This reverts commit cb8872577d66ff0fc38bcd70493be06bc0f34ffa.
2020-05-24syscallcompat: warn when Getdents truncates dataJakob Unterwurzacher
On CIFS mounts, unix.Getdents can return sudden ENOENT in the middle of data. This will not be reported as an error by user space tools, so return EIO instead. Also log it as a warning. https://github.com/rfjakob/gocryptfs/issues/483
2020-05-24fusefrontend: don't always clear the dircache in RenameJakob Unterwurzacher
When filename encryption is on, we do know when we overwrite a directory, and can clear only in this case. sshfs-benchmark.bash: sshfs gocryptfs-on-sshfs git init 1.74 7.80 rsync 6.19 11.63
2020-05-24fusefrontend: don't clear dircache on MkdirJakob Unterwurzacher
Mkdir can not cause existing entries in the cache to go stale. So don't clear it. Benchmark results: sshfs-benchmark.bash: sshfs gocryptfs-on-sshfs git init 1.65 8.74 rsync 6.09 17.54
2020-05-23syscallcompat: getdents: retry on EINTRJakob Unterwurzacher

2020-05-17dircache: increase cache size & lifetimeJakob Unterwurzacher
Looking at the dircache debug output, we see that a "git status" workload has a very bad cache hit rate because the entries expire or get evicted before they can be reused. Increase both cache size and lifetime for a 4x speedup: Before: 75s After: 17s https://github.com/rfjakob/gocryptfs/issues/410

2020-05-17main: accept multiple -passfile optionsJakob Unterwurzacher
Each file will be read and then concatenated for the effictive password. This can be used as a kind of multi-factor authenticiton. Fixes https://github.com/rfjakob/gocryptfs/issues/288
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.
