fusefrontend: replace unreliable "fd < 0" check

2016-05-30T07:36:06+00:00

... with the "released" boolean. For some reason, the "f.fd.Fd() < 0" check did not work reliably, leading to nil pointer panics on the following wlock.lock(). The problem was discovered during fsstress testing and is unlikely to happen in normal operations. With this change, we passed 1700+ fsstress iterations.

fusefrontend: use sync.Once for one-time warnings

2016-05-29T20:50:03+00:00

Using a simple boolean was racy (which was harmless in this case) and non-idomatic.

fusefronted: check Fstat return value on file create

2016-05-29T20:43:48+00:00

The Fstat call should never fail, but still, if it does return an error it should be handled properly.

fusefrontend: simplify wlockMap

2016-05-29T20:40:05+00:00

mapMutex can be anonymous and using an RWMutex is overkill because the lock protects very short sections.

fusefrontend: remove unused "forgotten" variable

2016-05-29T11:46:47+00:00

The functionality has long been replaced by the fd < 0 check.

Encrypt path in statfs() calls

2016-05-12T21:24:39+00:00

Paths in statfs() calls were not encrypted resulting in an Function not implemented error, when the unencrypted path didn't exist in the underlying (encrypted) filesystem. $ df plain/existingdir df: ‘plain/existingdir’: Function not implemented

fusefrontend: fix panic due to concurrently unregistered wlock

2016-05-08T21:21:20+00:00

Commit 730291feab properly freed wlock when the file descriptor is closed. However, concurrently running Write and Truncates may still want to lock it. Check if the fd has been closed first.

fusefrontend: fix wlock memory leak

2016-05-05T11:38:39+00:00

The write lock was not freed on release, causing a slow memory leak. This was noticed by running extractloop.bash for 10 hours.

prelloc: warn and continue if fallocate(2) is not supported

2016-04-20T20:47:31+00:00

This makes gocryptfs work at all on ZFS. See https://github.com/rfjakob/gocryptfs/issues/22 .

Fix "go tool vet -shadow=true" warnings

2016-04-10T19:31:15+00:00

Among those one real bug.
