2020-10-26Add verity tests for deleted/renamed casesChong Cai

2020-10-26[vfs] kernfs: Implement LRU cache for kernfs dentries.Ayush Ranjan
Much like the VFS2 gofer client, kernfs too now caches dentries. The size of the LRU cache is configurable via mount options. Have adopted the same reference semantics from gofer client dentry. Only sysfs and procfs use this LRU cache. The rest of the kernfs users (devpts, fusefs, host, pipefs, sockfs) still use the no cache approach. PiperOrigin-RevId: 339139835

2020-10-26Add nogo configuration.Adin Scannell
This splits the nogo rules into a separate configuration yaml file, and allows for multiple files to be provided. Because attrs cannot be passed down to aspects, this required that all findings are propagated up the aspect Provider. This doesn't mean that any extra work must be done, just that this information must be carried through the graph, and some additional starlark complexity is required. PiperOrigin-RevId: 339076357

Inode number consistency checks are now skipped in save/restore tests for reasons described in greatest detail in StatTest.StateDoesntChangeAfterRename.

PiperOrigin-RevId: 338728070
2020-10-23//pkg/state fixes for VFS2.Jamie Liu
- When encodeState.resolve() determines that the resolved reflect.Value is contained by a previously-resolved object, set wire.Ref.Type to the containing object's type (existing.obj.Type()) rather than the contained value's type (obj.Type()). - When encodeState.resolve() determines that the resolved reflect.Value contains a previously-resolved object, handle cases where the new object contains *multiple* previously-resolved objects. (This may cause previously-allocated object IDs to become unused; to facilitate this, change encodeState.pending to a map, and change the wire format to prefix each object with its object ID.) - Add encodeState.encodedStructs to avoid redundant encoding of structs, since deduplication of objects via encodeState.resolve() doesn't work for objects instantiated by StateSave() and passed to SaveValue() (i.e. fields tagged `state:".(whatever)"`). - Make unexported array fields deserializable via slices that refer to them by casting away their unexportedness in decodeState.decodeObject().

2020-10-23Fix TestTCPTimeWaitNewSyn.Bhasker Hariharan
Drain the notification channel after first accept as in case the first accept never blocked then the notification for the first accept will still be in the channel causing the second accept to fail as it will try to wait on the channel and return immediately due to the older notification even though there is no connection yet in the accept queue.
