spdx: The BSD-2-Clause-FreeBSD identifier is obsolete, drop -FreeBSD

2023-05-12T16:44:03Z

The SPDX folks have obsoleted the BSD-2-Clause-FreeBSD identifier. Catch up to that fact and revert to their recommended match of BSD-2-Clause. Discussed with: pfg MFC After: 3 days Sponsored by: Netflix

lib: further adoption of SPDX licensing ID tags.

2017-11-26T02:00:33Z

Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

Make libcrypt thread-safe. Add crypt_r(3).

2016-08-10T15:16:28Z

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.

s/shaN_crypt/crypt_shaN/g to be a more consistent with the existing naming.

Add working and easy crypt(3)-switching. Yes, we need a whole new API

2000-08-22T02:15:54Z

for crypt(3) by now. In any case: Add crypt_set_format(3) + documentation to -lcrypt. Add login_setcryptfmt(3) + documentation to -lutil. Support for switching crypt formats in passwd(8). Support for switching crypt formats in pw(8). The simple synopsis is: edit login.conf; add a passwd_format field set to "des" or "md5"; go nuts :) Reviewed by: peter
