2020-09-17Change sizeofInt32 to string sizeChong Cai
This constant is used to represent int32 stored in file xattrs. The integers are stored as strings there, so the real size should be the string size (number of digits) instead of an int size (4 bytes). PiperOrigin-RevId: 332353217

2020-09-17fsimpl: improve the "implements" commentsTiwei Bie
As noticed by @ayushr2, the "implements" comments are not consistent, e.g. // IterDirents implements kernfs.inodeDynamicLookup. // Generate implements vfs.DynamicBytesSource.Generate. This patch improves this by making the comments like this consistently include the package name (when the interface and struct are not in the same package) and method name.

2020-09-16Implement OpenAt() for verity fsChong Cai
OpenAt() for verity fs is implemented by opening both the target file or directory and the corresponding Merkle tree file in the underlying file system. Generally they are only open for read. In allowRuntimeEnable mode, the Merkle tree file is also open for write. PiperOrigin-RevId: 332116423
2020-09-16Implement PRead for verity fsChong Cai
PRead is implemented by read from the underlying file in blocks, and verify each block. The verified contents are saved into the output buffer. PiperOrigin-RevId: 332092267

2020-09-08Implement ioctl with enable veritygVisor bot
ioctl with FS_IOC_ENABLE_VERITY is added to verity file system to enable a file as verity file. For a file, a Merkle tree is built with its data. For a directory, a Merkle tree is built with the root hashes of its children. PiperOrigin-RevId: 330604368

2020-08-31Implement walk in gvisor verity fsgVisor bot
Implement walk directories in gvisor verity file system. For each step, the child dentry is verified against a verified parent root hash. PiperOrigin-RevId: 329358747
2020-08-22Implement GetFilesystem for verity fsgVisor bot
verity GetFilesystem is implemented by mounting the underlying file system, save the mount, and store both the underlying root dentry and root Merkle file dentry in verity's root dentry. PiperOrigin-RevId: 327959334
