| | | | | | | consistent handling of negative ids on 32bit/64bit systems. The only negative uid/gid allowed is -1 which is special-cased so it can be preserved when writing the new master.passwd file instead of being written as an unsigned number. OK deraadt@

* Change pw_copy(3) to take a 3rd arguement, the existing passwd entry.millert2004-04-201-6/+31
| | | | | | | This allows an application to only update a password entry if it is in the state it expects. Additionally, if the old passwd struct is specified the new one may have a different pw_name field since matching is done on the original. Adapted from FreeBSD.

* Change the second arg to pw_mkdb() from a boolean flag to a set ofmillert2001-08-261-6/+6
| | | | | | | | | | | bit flags ORed together. Currently the only flags defined are _PASSWORD_SECUREONLY and _PASSWORD_OMITV7 but this is enough to cause pw_mkdb() to run pwd_mkdb with the options we want. With this change we no longer generate the old V7 passwd file when only the extra fields in master.passwd (or the encrypted password) have changed. There are other programs that could probably use the _PASSWORD_OMITV7 flag; they will be converted at a future date.

* warnx?/errx? paranoia (use "%s" not a bare string unless it is amillert2000-06-301-3/+3
| | | | | | | | | constant). These are not security holes but it is worth fixing them anyway both for robustness and so folks looking for examples in the tree are not misled into doing something potentially dangerous. Furthermore, it is a bad idea to assume that pathnames will not include '%' in them and that error routines don't return strings with '%' in them (especially in light of the possibility of locales).
