2020-10-27Add SHA512 to merkle tree libraryChong Cai
PiperOrigin-RevId: 339377254
2020-10-12Change Merkle tree library to use ReaderAtChong Cai
Merkle tree library was originally using Read/Seek to access data and tree, since the parameters are io.ReadSeeker. This could cause race conditions if multiple threads accesses the same fd to read. Here we change to use ReaderAt, and implement it with PRead to make it thread safe. PiperOrigin-RevId: 336779260
2020-10-09Include stat in Verity hashChong Cai
PiperOrigin-RevId: 336395445
2020-10-06Fix typo in merkletreegVisor bot
PiperOrigin-RevId: 335709552
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
2020-08-31Implement 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
2020-08-24Add check for same source in merkle tree libgVisor bot
If the data is in the same Reader as the merkle tree, we should verify from the first layer in the tree, instead of from the beginning. PiperOrigin-RevId: 328230988
2020-08-17Add Verify in merkle tree librarygVisor bot
Verify checks input data against the merkle tree, and compares the root hash with expectation. PiperOrigin-RevId: 327116711
2020-06-11Add Generate method in merkletreegVisor bot
A method is added to generate a merkle tree for data, and store the generated tree in the output. PiperOrigin-RevId: 315966571
2020-06-11Add merkle tree size measuregVisor bot
This change creates a merkletree package which will be used in the future for an implementation of file system API. PiperOrigin-RevId: 315952451
