Sometimes when an unexpected error occurs the cacher would set an
error and return. However, it would not broadcast the condition
signal in that case, therefore leaving the goroutine that runs
readChunkAt stuck forever.
I figured that the condition is unnecessary because readChunkAt is
acquiring a lock that is still held by the cacher goroutine anyway.
Callees of startCaching have to wait for a WaitGroup which makes sure
that readChunkAt can't acquire the lock before startCaching.
This way readChunkAt can execute normally and check for the error.
* Fix FUSE server buffer leaks in file gaps
This change zeros read buffers when encountering file gaps during
file/chunk reads in FUSE mounts.
It prevents leaking internal buffers of the FUSE server which could
otherwise reveal metadata, directory listings, file contents and
other data related to FUSE API calls.
The issue was that buffers are reused, but when a file gap was found
the buffer was not zeroed accordingly and the existing data of the
buffer was kept and returned.
* Move zero logic into its own method
* fix(filer.sync): initializing the offset is related to the path
* fix(filer.sync): the offset maybe to be set to 0.
