* crypt_r(3): fix reentrancy problems with DESEdward Tomasz Napierala2021-06-151-29/+29
| | | | | | | | | | | | | | | | | | | This code was originally written for non-reentrant crypt(3). In 5f521d7ba72, a thread-safe crypt_r(3) was introduced. However, it looks like the DES implementation is still not re-entrant; routines like setup_salt() or des_setkey() still use global variables. Instead of something drastic, eg removing DES support altogether, just mark those variables as thread-local. This adds about 30kB of data per thread. Given that this only applies to DES, I think the impact is minimal. Reviewed By: markj Sponsored by: NetApp, Inc. Sponsored by: Klara, Inc. Differential Revision: https://reviews.freebsd.org/D30674
* Make libcrypt thread-safe. Add crypt_r(3).Ed Schouten2016-08-102-59/+42
| | | | | | | | | | | | | | | | | | | | | | glibc has a pretty nice function called crypt_r(3), which is nothing more than crypt(3), but thread-safe. It accomplishes this by introducing a 'struct crypt_data' structure that contains a buffer that is large enough to hold the resulting string. Let's go ahead and also add this function. It would be a shame if a useful function like this wouldn't be usable in multithreaded apps. Refactor crypt.c and all of the backends to no longer declare static arrays, but write their output in a provided buffer. There is no need to do any buffer length computation here, as we'll just need to ensure that 'struct crypt_data' is large enough, which it is. _PASSWORD_LEN is defined to 128 bytes, but in this case I'm picking 256, as this is going to be part of the actual ABI.

* Refresh our implementation of OpenBSD's Blowfish password format.Xin LI2014-02-251-33/+52
| | | | | | | | | | | | | | | | | | | | | Notable changes: - Support of $2b$ password format to address a problem where very long passwords (more than 256 characters, when an integer overflow would happen and cause the length to wrap at 256). - Updated pseudo code in comments to reflect the reality. - Removed our local shortcut of processing magic string and rely on the centralized and tigntened validation. - Diff reduction from upstream. For now we are still generating the older $02a$ format of password but we will migrate to the new format once the format is formally finalized.

* Merge into a single US-exportable libcrypt, which only providesPeter Wemm2000-12-281-73/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | one-way hash functions for authentication purposes. There is no more "set the libcrypt->libXXXcrypt" nightmare. - Undo the libmd.so hack, use -D to hide the md5c.c internals. - Remove the symlink hacks in release/Makefile - the algorthm is set by set_crypt_format() as before. If this is not called, it tries to heuristically figure out the hash format, and if all else fails, it uses the optional auth.conf entry to chose the overall default hash. - Since source has non-hidden crypto in it there may be some issues with having the source it in some countries, so preserve the "secure/*" division. You can still build a des-free libcrypt library if you want to badly enough. This should not be a problem in the US or exporting from the US as freebsd.org had notified BXA some time ago. That makes this stuff re-exportable by anyone. - For consistancy, the default in absence of any other clues is md5. This is to try and minimize POLA across buildworld where folk may suddenly be activating des-crypt()-hash support. Since the des hash may not always be present, it seemed sensible to make the stronger md5 algorithm the default. All things being equal, no functionality is lost.
