2017-12-05Documentation: Add reverse mode benchmark resultsJakob Unterwurzacher
2017-11-21main: Add '-devrandom' commandline optionSebastian Lackner
Allows to use /dev/random for generating the master key instead of the default Go implementation. When the kernel random generator has been properly initialized both are considered equally secure, however: * Versions of Go prior to 1.9 just fall back to /dev/urandom if the getrandom() syscall would be blocking (Go Bug #19274) * Kernel versions prior to 3.17 do not support getrandom(), and there is no check if the random generator has been properly initialized before reading from /dev/urandom This is especially useful for embedded hardware with low-entroy. Please note that generation of the master key might block indefinitely if the kernel cannot harvest enough entropy.
2017-11-12main: add "-sharedstorage" flagJakob Unterwurzacher
At the moment, it does two things: 1. Disable stat() caching so changes to the backing storage show up immediately. 2. Disable hard link tracking, as the inode numbers on the backing storage are not stable when files are deleted and re-created behind our back. This would otherwise produce strange "file does not exist" and other errors. Mitigates https://github.com/rfjakob/gocryptfs/issues/156
2017-10-19MANPAGE: explain that you may have to pass -aessiv with -masterkeyJakob Unterwurzacher
...if the filesystem was created with that option (or reverse mode). Mitigates https://github.com/rfjakob/gocryptfs/issues/148
2017-09-10performance.txt: specify READ testsJakob Unterwurzacher
2017-09-03performance.txt: update for v1.4.1 latest commits, and kernel updateJakob Unterwurzacher
$ uname -a Linux brikett 4.12.5-300.fc26.x86_64 #1 SMP Mon Aug 7 15:27:25 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
2017-08-21MANPAGE: update exit codesJakob Unterwurzacher
The exit codes have been documented in CLI_ABI.md for a while, but they should also be listed in the man page. Also fix the rendering of "[-o COMMA-SEPARATED-OPTIONS]", where the square brackets where interpreted as something. Escape all square brackets to be safe.
2017-08-15Update performance.txt for Linux kernel upgradeJakob Unterwurzacher
For some reason, writing became a lot faster in Linux 4.11 (scheduler improvements?).

Massive speed boost for streaming reads.

2017-06-20MANPAGE: reorder options to match "-hh" output; add "-hkdf", "-trace"Jakob Unterwurzacher
2017-06-11Add performance numbers for v1.3-69-ge52594dJakob Unterwurzacher
2017-06-11Add performance numbers for last changeJakob Unterwurzacher
Slight streaming write improvement.
2017-06-09performance.txt: add numbers for latest changeJakob Unterwurzacher
Also, get rid of the half-empty line.
2017-06-01Don't cap GOMAXPROCS at 4.Jakob Unterwurzacher
Before Go 1.5, GOMAXPROCS defaulted to 1, hence it made sense to unconditionally increase it to 4. But since Go 1.5, GOMAXPROCS defaults to the number of cores, so don't keep it from increasing above 4. Also, update the performance numbers.
2017-06-01Implement force_owner option to display ownership as a specific user.Charles Duffy
2017-05-30main: add "-info" optionJakob Unterwurzacher
Pretty-prints the config while stripping out sensitive (and uninteresting) data https://github.com/rfjakob/gocryptfs/issues/111

Needs a leading "..".
2017-05-14doc: update CLI_ABI.md with new exit codesJakob Unterwurzacher
All exit codes that are likely to occour are listed.
2017-04-24forcedecode: tighten checksJakob Unterwurzacher
...and fix a few golint issues and print a scary warning message on mount. Also, force the fs to ro,noexec.
2017-04-23Add -forcedecodedanim7
Force decode of encrypted files even if the integrity check fails, instead of failing with an IO error. Warning messages are still printed to syslog if corrupted files are encountered. It can be useful to recover files from disks with bad sectors or other corrupted media. Closes https://github.com/rfjakob/gocryptfs/pull/102 .
2017-03-28MANPAGE: reformat to GFM (github flavored markdown)Jakob Unterwurzacher
This makes it render properly on the github webinterface.
2017-03-25MANPAGE: fix alphabetical order and expand scryptn explainationJakob Unterwurzacher
2017-03-25Further explain the use of 'scryptn' parameter (#94)danim7
* Further explain the use of 'scryptn' parameter * Further explain the use of 'scryptn' parameter in MANPAGE * Use 28 as reasonable upper limit
2017-03-25README: use pre-rendered PNG logoJakob Unterwurzacher
This keeps the README working even if nuetzlich.net is unavailable. We use a PNG because github disallows embedding local SVGs.
2017-03-19MANPAGE: document "-serialize_reads"Jakob Unterwurzacher
2017-03-18benchmark: add md5sum read performance benchmarkJakob Unterwurzacher
2017-03-01CLI_ABI: smaller markdown subheadingsrfjakob
The old ones were rendered by github almost as big as the parent headings.

2016-11-26performance.txt: add numbers for current gocryptfs master and encfs v1.9.1Jakob Unterwurzacher
2016-11-26benchmark.bash: double write lengthJakob Unterwurzacher
Writing 1000 128KB blocks takes only 1 second and yielded inconsistent results. With 2000, things look saner.
2016-11-25main, fusefrontend: add "-noprealloc" optionJakob Unterwurzacher
Preallocation is very slow on hdds that run btrfs. Give the user the option to disable it. This greatly speeds up small file operations but reduces the robustness against out-of-space errors. Also add the option to the man page. More info: https://github.com/rfjakob/gocryptfs/issues/63
2016-11-11MANPAGE: document ctlsockJakob Unterwurzacher
2016-11-01main: rename "-f" to "-fg"Jakob Unterwurzacher
"-f" looks too much like "--force". The old variant is still accepted for compatability.

2016-11-01MANPAGE: add reverse example, move "-o" into alphabetical listJakob Unterwurzacher
People will search for "-o" alphabetically, so put it into the alphabetical option list, even if it is not a real option.
