2017-03-05configfile: switch to 128-bit IVs for master key encryptionJakob Unterwurzacher
There is no security reason for doing this, but it will allow to consolidate the code once we drop compatibility with gocryptfs v1.2 (and earlier) filesystems.
2016-12-10Replace all calls to naked panic() with log.Panic()Jakob Unterwurzacher
We want all panics to show up in the syslog.
2016-10-28fusefrontend: I/O error instead of panic on all-zero nonceJakob Unterwurzacher
Running xfstests generic/075 on tmpfs often triggered a panic for what seems to be a tmpfs bug. Quoting from the email to lkml, http://www.spinics.net/lists/kernel/msg2370127.html : tmpfs seems to be incorrectly returning 0-bytes when reading from a file that is concurrently being truncated.

2016-09-29reverse: use per-purpose nonce generationJakob Unterwurzacher
Also pull all the deterministic nonce code into fusefrontend_reverse to greatly simplify the normal code path.
2016-09-26reverse: switch from GCM-SIV to AES-SIVv1.1-beta1Jakob Unterwurzacher
GCM-SIV is not yet finalized, and the reference implemenation is painfully slow at about 2 MB/s. Switch to AES-SIV.
2016-09-25contentenc: rename constant "IVBitLen" to "DefaultIVBits" and clarify commentJakob Unterwurzacher
128-bit IVs are NOT used everywhere.
2016-09-25contentenc: add "ExternalNonce" modeJakob Unterwurzacher
This will be used for strong symlink encryption in reverse mode.
2016-09-25reverse: derive file ID and block IVs from file pathsJakob Unterwurzacher
2016-09-25contentenc: add GCM-SIV supportJakob Unterwurzacher
Also add ReverseDummyNonce nonce generation.
2016-09-25cryptocore: add support for GCM-SIVJakob Unterwurzacher
2016-09-25reverse: print value in file offset panicJakob Unterwurzacher
2016-09-25contentenc: add helpers for reverse modeJakob Unterwurzacher
Add the reverse variant of DecryptBlocks etc: * EncryptBlocks * JointPlaintextRange * ExplodeCipherRange
2016-09-25conentenc: handle zero-sized files in PlainSizeToCipherSizeJakob Unterwurzacher
Previously caused an integer underflow.
2016-07-06Add godoc comments to all internal packagesJakob Unterwurzacher
2016-07-02fusefronted: move Truncate() and Allocate() to their own fileJakob Unterwurzacher
These are large complicated implementations that will share some code.
2016-07-02contentenc: rename PlaintextRange and CiphertextRangeJakob Unterwurzacher
The name could be misunderstood and actually caused a bug: doWrite used to always preallocate 4128 instead of the actual data length.
2016-07-01fusefrontend: coalesce grows in Truncate()Jakob Unterwurzacher
We were growing the file block-by-block which was pretty inefficient. We now coalesce all the grows into a single Ftruncate. Also simplifies the code! Simplistic benchmark: Before: $ time truncate -s 1000M foo real 0m0.568s After: $ time truncate -s 1000M foo real 0m0.205s
2016-06-16Rename nametransform, contentenc source filesJakob Unterwurzacher
Let's have shorter names, and merge *_api.go into the "main" file. No code changes.
2016-06-15Rename internal "toggledlog" package to "tlog"Jakob Unterwurzacher
tlog is used heavily everywhere and deserves a shorter name. Renamed using sed magic, without any manual rework: find * -type f -exec sed -i 's/toggledlog/tlog/g' {} +
2016-03-03Enable openssl in tests to support old Go versionsJakob Unterwurzacher
Go 1.4 and older do not support 128-bit IVs which caused the tests to panic.
