2021-12-08tests: convert Creat() calls to Open()Jakob Unterwurzacher
Creat() is equivalent to Open(..., O_CREAT|O_WRONLY|O_TRUNC, ...) and MacOS does not have syscall.Creat(). https://github.com/rfjakob/gocryptfs/issues/623
2021-12-08crossbuild.bash: use shell function instead of variableJakob Unterwurzacher
This will allow easy expansion of build steps.
2021-12-04MANPAGE: fix typoJakob Unterwurzacher
2021-12-04MANPAGE: -extpass: document dash duplication bugJakob Unterwurzacher
Closes https://github.com/rfjakob/gocryptfs/issues/621
2021-11-01docs: names longer than 175 bytes (not 176) are stored in longnamesJakob Unterwurzacher
Quoting fusefrontend_reverse/node_helpers.go : // File names are padded to 16-byte multiples, encrypted and // base64-encoded. We can encode at most 176 bytes to stay below the 255 // bytes limit: // * base64(176 bytes) = 235 bytes // * base64(192 bytes) = 256 bytes (over 255!) // But the PKCS#7 padding is at least one byte. This means we can only use // 175 bytes for the file name. Noticed by @bailey27 at https://github.com/rfjakob/gocryptfs/issues/499#issuecomment-955790427
2021-10-21nametransform: fix math.MaxInt build failure on older GoJakob Unterwurzacher
Failure is: # github.com/rfjakob/gocryptfs/v2/internal/nametransform internal/nametransform/names.go:47:33: undefined: math.MaxInt math.MaxInt was only introduced in Go 1.17. Use MaxInt32 instead, which is good enough, even on amd64. It only has to be larger than any name we might encounter.
2021-10-21cli: add -longnamemaxJakob Unterwurzacher
Fixes https://github.com/rfjakob/gocryptfs/issues/499
2021-10-21configfile: add LongNameMax supportJakob Unterwurzacher
Feature flag + numeric paramater https://github.com/rfjakob/gocryptfs/issues/499
2021-10-21nametransform: add longNameMax parameterJakob Unterwurzacher
Determines when to start hashing long names instead of hardcoded 255. Will be used to alleviate "name too long" issues some users see on cloud storage. https://github.com/rfjakob/gocryptfs/issues/499
2021-10-21configfile: replace broken switch/case logic with ifJakob Unterwurzacher
Because switch only matches once, we could have missed invalid cases. Replace the switch statements with a straight if rake.

2021-09-28build.bash: also try BSD date syntax for converting SOURCE_DATE_EPOCHJakob Unterwurzacher
GNU date syntax does not work on macos. Fixes https://github.com/rfjakob/gocryptfs/issues/570
2021-09-28-init: suggest xchacha if we don't have AES accelJakob Unterwurzacher
Example on Raspberry Pi 4: $ ./gocryptfs/gocryptfs -init $(mktemp -d) Notice: Your CPU does not have AES acceleration. Consider using -xchacha for better performance. Choose a password for protecting your files. Password: https://github.com/rfjakob/gocryptfs/issues/607
2021-09-28-info: add contentEncryptionJakob Unterwurzacher
Example: $ ./gocryptfs -info ./tests/example_filesystems/v2.2-xchacha/ Creator: gocryptfs v2.1-27-gabaa129-dirty.xchacha FeatureFlags: HKDF XChaCha20Poly1305 DirIV EMENames LongNames Raw64 EncryptedKey: 64B ScryptObject: Salt=32B N=1024 R=8 P=1 KeyLen=32 contentEncryption: XChaCha20-Poly1305
2021-09-28cryptocore: disentangle algorithm / library implementation nameJakob Unterwurzacher
Used in gocryptfs-xray, and will also be used in -info.
2021-09-25README: set v2.2.0 release datev2.2.0Jakob Unterwurzacher
2021-09-25README: make changelog entries subheadingsJakob Unterwurzacher
This allows to anchor-link in to each release.
2021-09-15README: release will be called v2.2.0 instead of v2.2v2.2.0-beta2Jakob Unterwurzacher
pkg.go.dev really wants that we want to comply with https://golang.org/doc/modules/version-numbers . Trying v2.2-beta1 as in https://pkg.go.dev/github.com/rfjakob/gocryptfs/v2@v2.2-beta1 said "v2.2-beta1 is not a valid semantic version.".
2021-09-14-speed: print cpu modelJakob Unterwurzacher
When somebody posts "gocryptfs -speed" results, they are most helpful together with the CPU model. Add the cpu model to the output. Example: $ ./gocryptfs -speed gocryptfs v2.2.0-beta1-5-g52b0444-dirty; go-fuse v2.1.1-0.20210825171523-3ab5d95a30ae; 2021-09-14 go1.17.1 linux/amd64 cpu: Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz; with AES acceleration AES-GCM-256-OpenSSL 862.79 MB/s AES-GCM-256-Go 997.71 MB/s (selected in auto mode) AES-SIV-512-Go 159.58 MB/s XChaCha20-Poly1305-OpenSSL 729.65 MB/s XChaCha20-Poly1305-Go 843.97 MB/s (selected in auto mode)
2021-09-14stupidgcm: add CpuHasAES()Jakob Unterwurzacher
Makes the code clearer, and will be used in the next commit.

2021-09-10inomap: deterministically set root deviceJakob Unterwurzacher
We used to have "first Translate() wins". This is not deterministic, as the LOOKUP for the root directory does not seem to reach us, so the first user LOOKUP would win, which may be on a mountpoint.
2021-09-10README: update changelog for v2.2-beta1v2.2.0-beta1Jakob Unterwurzacher
2021-09-10Update README & MANPAGEJakob Unterwurzacher
2021-09-10cli: drop -forcedecode flagJakob Unterwurzacher
The rewritten openssl backend does not support this flag anymore, and it was inherently dangerour. Drop it (ignored for compatibility)
2021-09-10test.bash: call out if build-without-openssl.bash failedJakob Unterwurzacher
This can print out compile errors that are hard to understand if you are not aware that it builds without_openssl.
2021-09-10profiling: accept parameters & show actual command linesJakob Unterwurzacher
2021-09-08-speed: show which xchacha implementation is preferredJakob Unterwurzacher
2021-09-08tests/matrix: test xchacha with and without opensslJakob Unterwurzacher
2021-09-08Make -openssl also apply to xchachaJakob Unterwurzacher
Now that stupidgcm supports xchacha, make it available on mount.
2021-09-08stupidgcm: add PreferOpenSSL{AES256GCM,Xchacha20poly1305}Jakob Unterwurzacher
Add PreferOpenSSLXchacha20poly1305, rename PreferOpenSSL -> PreferOpenSSLAES256GCM.
2021-09-07stupidgcm: normalize constructor namingJakob Unterwurzacher
New() -> NewAES256GCM() Also add missing NewChacha20poly1305 constructor in without_openssl.go.
2021-09-07stupidgcm: revamp package documentationJakob Unterwurzacher
Maybe interesting for people following https://github.com/rfjakob/gocryptfs/issues/452
2021-09-07stupidgcm: unexport stupidGCM structJakob Unterwurzacher
No need to have it exported.
2021-09-07stupidgcm: allow zero-length input dataJakob Unterwurzacher
We used to panic in this case because it is useless. But Go stdlib supports it, so we should as well.
2021-09-07stupidgcm: fix build with CGO_ENABLED=1 without_opensslJakob Unterwurzacher
We missed some "// +build" lines
2021-09-07stupidgcm: NewChacha20poly1305: avoid slice appendJakob Unterwurzacher
I noticed that growslice() shows up in the cpuprofile. Avoiding slice append for the private jey copy gives a 0.6% speedup: gocryptfs/internal/speed$ benchstat old new name old time/op new time/op delta StupidXchacha-4 5.68µs ± 0% 5.65µs ± 0% -0.63% (p=0.008 n=5+5) name old speed new speed delta StupidXchacha-4 721MB/s ± 0% 725MB/s ± 0% +0.63% (p=0.008 n=5+5)
2021-09-07stupidgcm: add testConcurrencyJakob Unterwurzacher
Verifies that we don't corrupt data when called concurrently.
2021-09-07stupidgcm: cache C.EVP_chacha20_poly1305()Jakob Unterwurzacher
2% performance improvement, almost for free. gocryptfs/internal/speed$ benchstat old new name old time/op new time/op delta StupidXchacha-4 5.82µs ± 0% 5.68µs ± 0% -2.37% (p=0.008 n=5+5) name old speed new speed delta StupidXchacha-4 704MB/s ± 0% 721MB/s ± 0% +2.43% (p=0.008 n=5+5)
