* Small fix for the following problems:Bill Paul1995-04-291-2/+10
| | | | | | | | | | | | | | | | - If you take the wheel entry out of /etc/group and turn on NIS, the '+:*::' line is incorrectly flagged as the entry for wheel (the empty gid section is translated to 0), hence getgrgid() returns '+' as the name of the group instead of 'wheel.' - Using just '+:' as the 'turn on NIS' switch in /etc/group makes getgrgid() dump core because of a null pointer dereference. (Last time I was in here, I foolishly assumed that fixing the core dump problems with getgrnam() and getgrent() would fix getgrgid() too. Silly me.) Notes: svn path=/head/; revision=8172

| | | | | | | | | | - it succeeded on non-directories (see POSIX 5.1.2.4). - it hung on (non-open) named pipes. - it leaked memory if the second malloc() failed. - it didn't preserve errno across errors in close(). Notes: svn path=/head/; revision=7978

If you end your +@netgroup list with the wildcard line (+:::::::::) then you'll have a +@netgroup list that remaps the specified people but leaves people not in any netgroup unaffected.

* As per Justin T. Gibbs's request, agument the +@netgroup/-@netgroupBill Paul1995-03-241-36/+72
| | | | | | | | | | | | | | | | remapping mechanism in the following manner: if given an entry +@foo and there is no netgroup named 'foo,' try searching for a regular user group called 'foo' and build the cache using the members of group 'foo' instead. If both a netgroup 'foo' and a user group 'foo' exist, the 'foo' netgroup takes precedence, since we're primarily interested in netgroup matching anyway. This allows access control schemes based on ordinary user groups (which are also available via NIS) rather than netgroups, since netgroups on some systems are limited in really brain-damaged ways. Notes: svn path=/head/; revision=7319
* Don't let setnetgrent() operate on a null or empty group name: it canBill Paul1995-03-231-0/+4
| | | | | | | tickle a bug in ypserv and make a serious mess of things. Notes: svn path=/head/; revision=7289
* Very important sanity checks: today I clobbered all four NIS servers onBill Paul1995-03-231-6/+8
| | | | | | | | | | | | | | | | my network because setnetgrent() was trying to do a lookup on group "". It seems that an attempt to do a yp_match() (and possible yp_next()) on a null or empty key causes Sun's ypserv in SunOS 4.1.3 to exit suddenly (and without warning). Our ypserv behaves badly in this situation too, thoush it doesn't appear to crash. In any event, getpwent, getnetgrent and yp_match() and yp_next() are now extra careful not to accidentally pass on null or empty arguments. Also made a small change to getpwent.c to allow +::::::::: wildcarding, which I had disabled previously. Notes: svn path=/head/; revision=7288
* Lots of fixes/improvements in the +user substitution handling:Bill Paul1995-03-231-52/+39
| | | | | | | | - Have the +@netgroup/-@netgroup caches handle the +user/-user cases too. - Clean up getpwent() to take advantage of the improved +user/-user handling. Notes: svn path=/head/; revision=7278
* Small cleanups:Bill Paul1995-03-231-39/+44
| | | | | | | | | - Prepend a '_' to a couple of things - Make sure YP is enabled in _createcaches() - Remove a couple of unused/uneeded variables from _createcaches() Notes: svn path=/head/; revision=7262
* Phew! Done at last: getpwent now understands +@netgroup/-@netgroup directivesBill Paul1995-03-231-9/+212
| | | | | | | | in addition to the existing NIS substitutions. I may tweak this a bit in the future, but the important stuff is all here. Notes: svn path=/head/; revision=7258
* Use better/stronger/faster NIS lookup code: by using yp_match() instead ofBill Paul1995-03-211-44/+14
| | | | | | | | the yp_first()/yp_next() combo, we let the database code in ypserv do some of the work for us. Notes: svn path=/head/; revision=7223
* Whoops: expanding netgroups that reference multiple netgroups doesn'tBill Paul1995-03-191-1/+1
| | | | | | | | | | | | | | | | | | work because parse_netgrp() doesn't recurse properly. Fixed by changing if (parse_netgrp(spos)) return(1); to if (parse_netgrp(spos)) continue; inside parse_netgrp(). (Lucky for me I happen to have a fairly complex 'live' netgroup database to test this stuff with.) Notes: svn path=/head/; revision=7175
* Two major changes:Bill Paul1995-03-191-4/+71
| | | | | | | | | | | | | | | | | - Added support for reading netgroups from NIS/YP in addition to the local /etc/netgroups file. (Note that SunOS and many other systems only support reading netgroups via NIS, which is a bit odd.) - Fix Evil Null Pointer Dereferences From Hell (tm) that caused parse_netgrp() to SEGV when expanding netgroups that include references to other netgroups. Funny how nobody else noticed this. This is the first step in implimenting +@netgroup substitution in getpwent.c and any other places that could use it and don't already support it (which is probably everywhere). Notes: svn path=/head/; revision=7149
* Fix 'putting +: in /etc/group causes many programs to dump core' bugBill Paul1995-03-181-1/+11
| | | | | | | | | | | | by heading off possible null pointer dereferences in grscan(). Also change getgrnam() slightly to properly handle the change: if grscan() returns an rval of 1 and leaves a '+' in the gr_name field and YP is enabled, poll the YP group.byname map before giving up. This should insure that we make every effort to find a match in the local and YP group databases before bailing out. Notes: svn path=/head/; revision=7124
