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.

toggledlog: wpanic: use Logger.Panic instead of naked panic

2016-05-30T07:26:59+00:00

This makes sure the panic message also ends up in syslog (if enabled).

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The functionality has long been replaced by the fd 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.

stupidgcm: add benchmark.bash wrapper

2016-05-22T13:49:09+00:00

Add a simple bash wrapper to make it easier to run the GCM benchmarks.

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

prefer_openssl: add amd64 constraint

2016-05-12T07:50:36+00:00

Optimized assembly versions for Go GCM are only available on amd64.

prefer_openssl: autodetect whether to use OpenSSL or Go GCM

2016-05-11T22:42:42+00:00

Go GCM is faster than OpenSSL if the CPU has AES instructions and you are running Go 1.6+. The "-openssl" option now defaults to "auto". "gocryptfs -debug -version" displays the result of the autodetection. See https://github.com/rfjakob/gocryptfs/issues/23 for details and benchmarks.
