Refactor ciphertext <-> plaintext offset translation functions2015-11-01T11:11:36+00:00Jakob Unterwurzacher2015-11-01T11:11:36+00:00urn:sha1:902babdf22199d73171716e643f1ffbb65e6fb48
Move all the intelligence into the new file address_translation.go.
That the calculations were spread out too much became apparent when adding
the file header. This should make the code much easier to modify in the
future.
Add file header (on-disk-format change)2015-11-01T00:38:27+00:00Jakob Unterwurzacher2015-11-01T00:32:33+00:00urn:sha1:76311b60f2e208dbd93e1e7b6e9794770c14fede
Format: [ "Version" uint16 big endian ] [ "Id" 16 random bytes ]
Quoting SECURITY.md:
* Every file has a header that contains a 16-byte random *file id*
* Each block uses the file id and its block number as GCM *authentication data*
* This means the position of the blocks is protected as well. The blocks
can not be reordered or copied between different files without
causing an decryption error.
Use block number as authentication data2015-10-06T20:27:37+00:00Jakob Unterwurzacher2015-10-06T20:27:37+00:00urn:sha1:a3d286069f989dd16c6f91930a0df9fedfa2dd64Utimens: Use UtimesNano instead of Futimes2015-10-04T18:32:15+00:00Jakob Unterwurzacher2015-10-04T18:32:15+00:00urn:sha1:aa082c235a9ba2726385c07913bf1917faf928b2
Futimes() only takes microsecond resolution while the FUSE call
Utimens() wants nanosecond precision.
This is why UTIME_OMIT did not work - this change fixes the
xfstests generic/258 test failure.
The go library does not provide a FutimesNano() function which is
why I use UtimesNano() on /proc/self/fd/n.
This is what the Go library does in Futimes().
fallocate: return ENOSYS2015-10-04T15:14:40+00:00Jakob Unterwurzacher2015-10-04T15:14:40+00:00urn:sha1:c7313f36dee285a8adab801632c8d692bd5f5e7e
The implementation was incomplete, disable fallocate completely for now.

Fixes xfstests generic/075
truncate: Fix bug that caused xfstests generic/030 to fail2015-10-04T14:04:25+00:00Jakob Unterwurzacher2015-10-04T14:04:25+00:00urn:sha1:90bd9782831f9d3a3c7c682f9cc04ccef0a1666d
The bug was caused by using cipherOff where plainOff should
have been used.
Renamed the symbols for less confusion.
