Convert fdLock to an RWMutex and protect the whole transaction2016-01-24T23:51:28+00:00Jakob Unterwurzacher2016-01-24T23:51:28+00:00urn:sha1:4c9e249e3ac1fc2995e01eb1ed24799c3a3bc66b
...against concurrent closes.
The testcase
(set -e; while true; do truncate -s $RANDOM b; done) &
(set -e; while true; do truncate -s $RANDOM b; done) &
uncovered lots of unnecessary RMW failures that were the result
of concurrent closes.
With this patch, the only remaining error is "Truncate on forgotten file"
that is probably caused by a problem in the go-fuse lib
( https://github.com/hanwen/go-fuse/issues/95 )
Only warn once for unsupported fallocate(2) and truncate(2)2016-01-24T18:43:21+00:00Jakob Unterwurzacher2016-01-24T18:43:21+00:00urn:sha1:4259c8f7ebc9f5d167556ed142e82e8232706de6
Also, print the inode number in Ftruncate warnings.
Add per-inode write mutex2016-01-24T12:08:08+00:00Jakob Unterwurzacher2016-01-24T12:08:08+00:00urn:sha1:2f32114bd356c2124d75fb1879ff230fc1f0ca1b
At the moment, FUSE writes to a single file are serialized by the kernel.
However, it is unclear if this is guaranteed behaviour or may change
in the future.
This patch adds our own per-inode write lock to rule out races regardless
of kernel behavoir.
Convert logging to standard Go log.Logger2016-01-20T19:57:00+00:00Jakob Unterwurzacher2016-01-20T19:55:56+00:00urn:sha1:17f0eb13396ad31083e786ed64aef368646c2aa6
This is in preparation of logging to syslog.

This pushes back the birthday bound for collisions to make it virtually
irrelevant.
diriv: handle directory rename over directory2015-12-19T12:21:15+00:00Jakob Unterwurzacher2015-12-19T12:21:15+00:00urn:sha1:88826dc51d7919ef8b190c079955230e653323e2
If an empty directory is overwritten we will always get
ENOTEMPTY as the "empty" directory will still contain gocryptfs.diriv.
Handle that case by removing the target directory and trying again.
Fixes issue #10
