2016-05-12prefer_openssl: add amd64 constraintJakob Unterwurzacher
Optimized assembly versions for Go GCM are only available on amd64.
2016-05-12prefer_openssl: autodetect whether to use OpenSSL or Go GCMJakob Unterwurzacher
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.
2016-05-08fusefrontend: fix panic due to concurrently unregistered wlockJakob Unterwurzacher
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.
2016-05-05fusefrontend: fix wlock memory leakJakob Unterwurzacher
The write lock was not freed on release, causing a slow memory leak. This was noticed by running extractloop.bash for 10 hours.
2016-05-05stupidgcm: set dummy locking callback.v0.10-rc2Jakob Unterwurzacher
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.
2016-05-05stupidgcm: skip tests on Go 1.4 and olderJakob Unterwurzacher
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.
2016-05-05Revert "stupidgcm: print openssl error stack before panicing"Jakob Unterwurzacher
This did not help in debugging the openssl <= 1.0.1c issue at all and makes the code more complex. Keep it simple.
2016-05-05cryptocore: support Go 1.4 in testsJakob Unterwurzacher
2016-05-05stupidgcm: reorder calls to support openssl <= 1.0.1cJakob Unterwurzacher
This fixes the test failures on Travis CI. Quoting from https://github.com/openssl/openssl/commit/07a4ff79d23e45f1a45da717b7c1f41a5e1c7c0c /* Set expected tag value. A restriction in OpenSSL 1.0.1c and earlier * required the tag before any AAD or ciphertext */
2016-05-04stupidgcm: print openssl error stack before panicingJakob Unterwurzacher
2016-05-04stupidgcm: fix copy-paste error in panic messageJakob Unterwurzacher
Also, print the openssl version in Travis CI
2016-05-04stupidgcm: completely replace spacemonkeygo/opensslJakob Unterwurzacher
2016-05-04stupidgcm: add our own thin wrapper around openssl gcmJakob Unterwurzacher
...complete with tests and benchmark. This will allow us to get rid of the dependency to spacemonkeygo/openssl that causes problems on Arch Linux ( https://github.com/rfjakob/gocryptfs/issues/21 )
2016-05-04cryptocore: add API testsJakob Unterwurzacher
2016-04-20prelloc: warn and continue if fallocate(2) is not supportedJakob Unterwurzacher
This makes gocryptfs work at all on ZFS. See https://github.com/rfjakob/gocryptfs/issues/22 .
2016-04-10Fix "go tool vet -shadow=true" warningsJakob Unterwurzacher
Among those one real bug.
2016-04-10longnames: fix fsstress failure, use dirfdJakob Unterwurzacher
Using dirfd-relative operations allows safe lockless handling of the ".name" files.
2016-04-10longnames: use symbolic constants instead of naked intsJakob Unterwurzacher
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.
2016-03-03Fix Go 1.4 build failure caused by a refactoring oversightJakob Unterwurzacher
2016-02-07longnames part II: Rename, Unlink, Rmdir, Mknod, Mkdir + testsv0.9-rc1Jakob Unterwurzacher
2016-02-07Move OpenDir to fs_dir.goJakob Unterwurzacher
2016-02-07Add tests for long name creation and renaming (currently failing, obviously)Jakob Unterwurzacher
2016-02-06longnames part I: Create and OpenDir work with long filenames > 176 bytesJakob Unterwurzacher
Todo: Rename, Unlink, Rmdir, Mknod, Mkdir
2016-02-06Move dirIVCache to its own fileJakob Unterwurzacher
