2019-05-20Forward named pipe creation to the goferMichael Pratt
The backing 9p server must allow named pipe creation, which the runsc fsgofer currently does not. There are small changes to the overlay here. GetFile may block when opening a named pipe, which can cause a deadlock: 1. open(O_RDONLY) -> copyMu.Lock() -> GetFile() 2. open(O_WRONLY) -> copyMu.Lock() -> Deadlock A named pipe usable for writing must already be on the upper filesystem, but we are still taking copyMu for write when checking for upper. That can be changed to a read lock to fix the common case. However, a named pipe on the lower filesystem would still deadlock in open(O_WRONLY) when it tries to actually perform copy up (which would simply return EINVAL). Move the copy up type check before taking copyMu for write to avoid this. p9 must be modified, as it was incorrectly removing the file mode when sending messages on the wire.

2018-10-23Track paths and provide a rename hook.Adin Scannell
This change also adds extensive testing to the p9 package via mocks. The sanity checks and type checks are moved from the gofer into the core package, where they can be more easily validated. PiperOrigin-RevId: 218296768 Change-Id: I4fc3c326e7bf1e0e140a454cbacbcc6fd617ab55

2018-07-02Drop version option from mount commandMichael Pratt
Fun fact: in protocol version negotiation, our 9p version must be written "9P2000.L". In the 'version' mount option, it must be written "9p2000.L". Very consistent! The mount command as given complains about an unknown protocol version. Drop it entirely because Linux defaults to 9p2000.L anyways.
