Downgrade the message to "info" level if we are on XFS. Using the "warning" level means that users on old XFS filesystems cannot run the test suite as it intentionally aborts on any warnings. Fixes https://github.com/rfjakob/gocryptfs/issues/267 tests: syscallcompat: allow failure for symlinks > 1000 2018-10-11T17:45:47+00:00 Jakob Unterwurzacher 2018-10-11T17:45:47+00:00 urn:sha1:57a5a8791f8a8c957aef87aecfa4fa318873b744 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 syscallcompat: untangle Openat flag check 2018-09-22T17:38:47+00:00 Jakob Unterwurzacher 2018-09-22T17:38:47+00:00 urn:sha1:737a2f2012baf3f11056e08232c8d34dc353e2d8 Check for O_NWFOLLOW and O_EXCL separately to make the logic clearer. syscallcompat: use O_PATH in OpenDirNofollow 2018-09-08T16:06:33+00:00 Jakob Unterwurzacher 2018-09-08T16:06:33+00:00 urn:sha1:930c37e03d5ff80e7cdc9f0ca2cd35d80a06d5c0 This fixes the "0100 directory" problem in reverse mode, and should be slightly faster. syscallcompat: untangle OpenNofollow and rename to OpenDirNofollow 2018-09-08T15:41:17+00:00 Jakob Unterwurzacher 2018-09-08T15:41:17+00:00 urn:sha1:9ec9d0c49cfbdc9ceba10d7534b77e527c0a3cdc The function used to do two things: 1) Walk the directory tree in a manner safe from symlink attacks 2) Open the final component in the mode requested by the caller This change drops (2), which was only used once, and lets the caller handle it. This simplifies the function and makes it fit for reuse in forward mode in openBackingPath(), and for using O_PATH on Linux.
