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
2020-10-18syscallcompat: add getxattr fastpathsJakob Unterwurzacher
The allocations from Lgetxattr were #1 in the tar extract allocation profile (caused by security.capability lookups). No more! $ benchstat old.txt new.txt name old time/op new time/op delta Lgetxattr-4 15.2µs ± 0% 1.8µs ± 0% ~ (p=1.000 n=1+1) $ ./benchmark.bash Testing gocryptfs at /tmp/benchmark.bash.H8p: gocryptfs v2.0-beta1-4-g95ea738-dirty; go-fuse v2.0.4-0.20200908172753-0b6cbc515082 => github.com/rfjakob/go-fuse/v2 v2.0.4-0.20201015204057-88b12c99f8af; 2020-10-18 go1.15.3 linux/amd64 /tmp/benchmark.bash.H8p.mnt is a mountpoint WRITE: 262144000 bytes (262 MB, 250 MiB) copied, 0,520109 s, 504 MB/s READ: 262144000 bytes (262 MB, 250 MiB) copied, 0,255672 s, 1,0 GB/s UNTAR: 30,238 MD5: 12,721 LS: 10,038 RM: 16,536

2020-10-14syscallcompat: don't retry Close()Jakob Unterwurzacher
After Close() returns, the fd is dead, even if we received EINTR. Don't retry, we could shoot down an unrelated fd that received the same fd number.
2020-10-14syscallcompat: retry ops on EINTRJakob Unterwurzacher
Retry operations that have been shown to throw EINTR errors on CIFS. Todo: Solution for this pain in the back: warning: unix.Getdents returned errno 2 in the middle of data rm: cannot remove 'linux-3.0.old3/Documentation/ABI/removed': Input/output error Progress towards fixing https://github.com/rfjakob/gocryptfs/issues/483 .

2020-10-04build.bash: show "go mod edit -replace" in version stringJakob Unterwurzacher
If you do something like this, go mod edit -replace github.com/hanwen/go-fuse/v2=/home/jakob/go/src/github.com/hanwen/go-fuse the version string of the resulting binary should reflect that. Before: gocryptfs v1.8.0-135-g352b547-dirty.gofuse_v2api; go-fuse v2.0.4-0.20200908172753-0b6cbc515082; 2020-10-03 go1.15.2 linux/amd64 After: gocryptfs v1.8.0-135-g352b547-dirty.gofuse_v2api; go-fuse v2.0.4-0.20200908172753-0b6cbc515082 => /home/jakob/go/src/github.com/hanwen/go-fuse; 2020-10-03 go1.15.2 linux/amd64

2020-10-03fsstress-gocryptfs.bash: don't hang if TMPDIR ends in /Jakob Unterwurzacher
We would hang like this ./fsstress-loopback.bash Recompile go-fuse loopback: v2.0.3-7-g0b6cbc5 Waiting for mount: xxxxxxxx^C if TMPDIR has a trailing /. The reason is that the paths in /proc/self/mounts are normalized, while TMPDIR may not be.

2020-09-13stress_tests/fsstress-gocryptfs.bash: use rm -Rf for cleanupJakob Unterwurzacher
Apparently, kernel 5.8 now allows unprivileged "mknod /tmp/x c 0 0": vfs: allow unprivileged whiteout creation https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?h=v5.8.9&id=a3c751a50fe6bbe50eb7622a14b18b361804ee0c which is why rm throws a new prompt: rm: remove write-protected character special file '...'? Use rm -Rf to suppress that.
