1648c54adb fusefrontend: use sync.Once for one-time warnings 
Using a simple boolean was racy (which was harmless
in this case) and non-idomatic.

fd53dfd2ad fusefronted: check Fstat return value on file create 
The Fstat call should never fail, but still, if it does return an error
it should be handled properly.

77813bdc13 fusefrontend: simplify wlockMap 
mapMutex can be anonymous and using an RWMutex is overkill
because the lock protects very short sections.

9aeb639a15 fsstress-loopback: properly stop on Ctrl-C 
Send fsstress (which ignores Ctrl-C) into the background
so the shell gets the signal. Manually kill fsstress in the
cleanup handler.

Also, use the build.bash script for gocryptfs.

30f0ae3720 fsstress-loopback: use random directory names 
This allows to run more than one instance of
the script in parallel.

Also, properly clean up on exit.

b467e7509e stress_tests: add header comments 
Also, convert extractloop.bash to using md5sum instead of diff -ur
so the user does not have to keep an extracted kernel tree around.
And print the iteration time.

a93bcabe9c Encrypt path in statfs() calls 
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’: Function not implemented

4ad9d4e444 prefer_openssl: add amd64 constraint

49b597f07c prefer_openssl: autodetect whether to use OpenSSL or Go GCM 
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.

ba7c798418 fusefrontend: fix panic due to concurrently unregistered wlock 
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.

730291feab fusefrontend: fix wlock memory leak 
The write lock was not freed on release, causing a slow memory leak.

This was noticed by running extractloop.bash for 10 hours.

them to the main repo.

cf29ce3762 stupidgcm: set dummy locking callback. 
In general, OpenSSL is only threadsafe if you provide a locking function
through CRYPTO_set_locking_callback. However, the GCM operations that
stupidgcm uses never call that function.

To guard against that ever changing, set a dummy locking callback
that crashes the app.

906172938a stupidgcm: skip tests on Go 1.4 and older 
Quoting from the patch:

	We compare against Go's built-in GCM implementation. Since stupidgcm only
	supports 128-bit IVs and Go only supports that from 1.5 onward, we cannot
	run these tests on older Go versions.

b4d45554f2 Revert "stupidgcm: print openssl error stack before panicing" 
This did not help in debugging the openssl <= 1.0.1c issue at all
and makes the code more complex. Keep it simple.

This fixes the test failures on Travis CI.

Quoting from 07a4ff79d2

	/* Set expected tag value. A restriction in OpenSSL 1.0.1c and earlier
	 * required the tag before any AAD or ciphertext */
