* The "always hint that getpw operation is happening with access() the YPderaadt2019-07-021-1/+7

* modify getpw*(), getgr*(), and getgrouplist() functions to access thederaadt2015-12-011-1/+8
| | | | | | | | | YP lock file unconditionally. This hints to the kernel that a "getpw" operation is happening, even in the non-YP case. This looks like a gruesome hack, but helps refine the ways these functions are called and mandates the right pledge requests. Once the tree is fully annotated we will know better how to improve the backing store management. ok semarie espie beck

* Fix the handle locking in stdio to use flockfile/funlockfilekurt2009-11-091-2/+2
| | | | | | | | | | | | | internally when and where required. Macros in <stdio.h> are updated to automatically call the underlying functions when the process is threaded to obtain the necessary locking. A private mutex is added to protect __sglue, the internal list of FILE handles, and another to protect the one-time initialization. Some routines in libc that use getc() change to use getc_unlocked() as they're either protected by their own lock or aren't thread-safe routines anyway. committing on behalf of and okay guenther@ now that we have install media space available.

* Take advantage of the surprise libc bump to bring inschwarze2009-06-031-4/+8
| | | | | | | | YP group(5) exclusion, i.e. support -groupname:*:: in /etc/group. Such groups will be excluded from later +:*::, in just the same was as it is already done for passwd(5). I have been running this since the autumn of 2008. Discussed with several (including deraadt@, millert@, jmc@).
* getgrouplist: If YP is #defined and enabled in /etc/group(5) and /etc/netid(5)schwarze2009-03-271-57/+119
| | | | | | | | | | | | | | contains a matching entry, use that and refrain from accessing YP. getpwnam/getpwuid: If YP is #defined and /etc/master.passwd(5) contains a matching entry before the first YP entry, use that and stay away from YP. Taken together, this allows a solution to the following problem pointed out by deraadt@: When YP was configured but temporarily unavailable, even root login would block, hindering you when trying to do repairs. To avoid this, you can now provide a static entry for root in /etc/netid. Using suggestions from miod@ otto@ blambert@ jmc@. "commit" deraadt@, "cool" ajacoutot@, "looks fine" jmc@.
