2021-12-09darwin: use O_NOFOLLOW for xattr opensJakob Unterwurzacher
Running the tests we have lots of these: Openat: O_NOFOLLOW missing: flags = 0x4 -wpanic turns this warning into a panic: Openat: O_NOFOLLOW missing: flags = 0x4 panic: -wpanic turns this warning into a panic: Openat: O_NOFOLLOW missing: flags = 0x4 goroutine 114 [running]: log.(*Logger).Panic(0x14000118280, {0x14000313ca8, 0x1, 0x1}) log/log.go:224 +0x90 github.com/rfjakob/gocryptfs/v2/internal/tlog.(*toggledLogger).Printf(0x14000076780, {0x1009dc2e8, 0x27}, {0x14000313d18, 0x1, 0x1}) github.com/rfjakob/gocryptfs/v2/internal/tlog/log.go:78 +0x168 github.com/rfjakob/gocryptfs/v2/internal/syscallcompat.Openat(0x9, {0x1009d0747, 0x1}, 0x4, 0x0) github.com/rfjakob/gocryptfs/v2/internal/syscallcompat/sys_common.go:59 +0xf0 github.com/rfjakob/gocryptfs/v2/internal/fusefrontend.(*Node).getXAttr(0x14000142000, {0x1400001c140, 0x3a}) github.com/rfjakob/gocryptfs/v2/internal/fusefrontend/node_xattr_darwin.go:30 +0x8c github.com/rfjakob/gocryptfs/v2/internal/fusefrontend.(*Node).Getxattr(0x14000142000, {0x100a7eba0, 0x1400000c2e8}, {0x14000016348, 0x14}, {0x14000326000, 0x20, 0x4000}) github.com/rfjakob/gocryptfs/v2/internal/fusefrontend/node_xattr.go:65 +0x1ac github.com/hanwen/go-fuse/v2/fs.(*rawBridge).GetXAttr(0x1400008e140, 0x140001901e0, 0x140001133c0, {0x14000016348, 0x14}, {0x14000326000, 0x20, 0x4000}) github.com/hanwen/go-fuse/v2@v2.1.1-0.20210825171523-3ab5d95a30ae/fs/bridge.go:685 +0x114 github.com/hanwen/go-fuse/v2/fuse.doGetXAttr(0x14000144000, 0x14000113200) github.com/hanwen/go-fuse/v2@v2.1.1-0.20210825171523-3ab5d95a30ae/fuse/opcode.go:270 +0x224 github.com/hanwen/go-fuse/v2/fuse.(*Server).handleRequest(0x14000144000, 0x14000113200) github.com/hanwen/go-fuse/v2@v2.1.1-0.20210825171523-3ab5d95a30ae/fuse/server.go:499 +0x214 created by github.com/hanwen/go-fuse/v2/fuse.(*Server).loop github.com/hanwen/go-fuse/v2@v2.1.1-0.20210825171523-3ab5d95a30ae/fuse/server.go:470 +0xac https://github.com/rfjakob/gocryptfs/issues/625
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/%
2021-06-25fusefrontend: implement recursive diriv cachingJakob Unterwurzacher
The new contrib/maxlen.bash showed that we have exponential runtime with respect to directory depth. The new recursive diriv caching is a lot smarter as it caches intermediate lookups. maxlen.bash now completes in a few seconds. xfstests results same as https://github.com/rfjakob/fuse-xfstests/blob/2d158e4c82be85c15269af77498e353f928f4fab/screenlog.0 : Failures: generic/035 generic/062 generic/080 generic/093 generic/099 generic/215 generic/285 generic/319 generic/426 generic/444 generic/467 generic/477 generic/523 Failed 13 of 580 tests benchmark.bash results are identical: $ ./benchmark.bash Testing gocryptfs at /tmp/benchmark.bash.BdQ: gocryptfs v2.0.1-17-g6b09bc0; go-fuse v2.1.1-0.20210611132105-24a1dfe6b4f8; 2021-06-25 go1.16.5 linux/amd64 /tmp/benchmark.bash.BdQ.mnt is a mountpoint WRITE: 262144000 bytes (262 MB, 250 MiB) copied, 0,4821 s, 544 MB/s READ: 262144000 bytes (262 MB, 250 MiB) copied, 0,266061 s, 985 MB/s UNTAR: 8,280 MD5: 4,564 LS: 1,745 RM: 2,244
2021-06-02fusefrontend: run acl Setxattr in user contextJakob Unterwurzacher
The result of setting an acl depends on who runs the operation! Fixes fuse-xfstests generic/375 (see https://github.com/rfjakob/fuse-xfstests/wiki/results_2021-05-19)
