2020-10-18syscallcompat: add getxattr fastpathsJakob Unterwurzacher
The allocations from Lgetxattr were #1 in the tar extract allocation profile (caused by security.capability lookups).

2019-01-14tests: reduce noise on MacOSJakob Unterwurzacher
This should get rid of Openat: O_NOFOLLOW missing: flags = 0x0 Fchmodat: adding missing AT_SYMLINK_NOFOLLOW flag sys_common_test.go:203: chmod on symlink should have failed, but did not. New mode=0333 UnmountErr: "[...]/057376762.mnt" was not found in MountInfo, cannot check for FD leak and add some context to --- FAIL: TestUtimesNano (0.00s) matrix_test.go:628: no such file or directory See https://github.com/rfjakob/gocryptfs/pull/343#issuecomment-453888006 for full test output
2019-01-14syscallcompat: fix FchmodatNofollow testsJakob Unterwurzacher
FchmodatNofollow dropped the flags parameter.
2019-01-14syscallcompat: rework Fchmodat to FchmodatNofollowJakob Unterwurzacher
We never want Fchmodat to follow symlinks, so follow what Qemu does, and call our function FchmodatNofollow.

2019-01-07tests: add Fchmodat testJakob Unterwurzacher
Test that we handle symlinks correctly.
2018-10-11tests: syscallcompat: allow failure for symlinks > 1000Jakob Unterwurzacher
MacOS and old XFS versions do not support very long symlinks, but let's not make the tests fail because of that. https://github.com/rfjakob/gocryptfs/issues/267
2018-02-28MacOS: don't test symlinks longer than 1000 bytesJakob Unterwurzacher
The limit is much lower than on Linux. https://github.com/rfjakob/gocryptfs/issues/213
2017-12-06syscallcompat: add ReadlinkatJakob Unterwurzacher
We need readlinkat to implement Readlink symlink-race-free.
