2020-10-03Fix kcov enabling and disabling procedures.Dean Deng
- When the KCOV_ENABLE_TRACE ioctl is called with the trace kind KCOV_TRACE_PC, the kcov mode should be set to KCOV_*MODE*_TRACE_PC. - When the owning task of kcov exits, the memory mapping should not be cleared so it can be used by other tasks. - Add more tests (also tested on native Linux kcov).

2020-10-01Add a verity test for modified parent Merkle fileChong Cai
When a child's root hash or its Merkle path is modified in its parent's Merkle tree file, opening the file should fail, provided the directory is verity enabled. The test for this behavior is added. PiperOrigin-RevId: 334963690

2020-09-30Add verity fs testsChong Cai
The tests confirms that when a file is opened in verity, the corresponding Merkle trees are generated. Also a normal read succeeds on verity enabled files, but fails if either the verity file or the Merkle tree file is modified. PiperOrigin-RevId: 334640331

2020-09-27Fix kernfs race condition.Dean Deng
Do not release dirMu between checking whether to create a child and actually inserting it. Also fixes a bug in fusefs which was causing it to deadlock under the new lock ordering. We do not need to call kernfs.Dentry.InsertChild from newEntry because it will always be called at the kernfs filesystem layer. Updates #1193. PiperOrigin-RevId: 334049264

2020-09-24[vfs] kernfs: Do not hold reference on the inode when opening FD.Ayush Ranjan
The FD should hold a reference on the dentry they were opened on which in turn holds a reference on the inode it points to. PiperOrigin-RevId: 333589223

2020-09-23fuse: don't call dentry.InsertChildAndrei Vagin
It is called from the kernfs code (OpenAt and revalidateChildLocked()). For RemoveChildLocked, it is opposed. We need to call it from fuse.RmDir and fuse.Unlink. PiperOrigin-RevId: 333453218

2020-09-21Allow partial writes for gofer.specialFileFD.Dean Deng
Originally, we avoided partial writes in case it caused us to write a partial packet to a socket-backed specialFileFD. However, this check causes splicing from a pipe to specialFileFD to fail if we hit EOF on the pipe. PiperOrigin-RevId: 333016216
