* Modify the implementation of libc semaphores so that they can beDaniel Eischen2004-02-031-146/+132
| | | | | | | | | | | | | | | overridden by the threads library to provide a userland version of non-pshared semaphores and cancellation points. Also add a sem_timedwait(). The libc version of semaphores always uses kernel semaphores regardless of whether pshared is set or not. When threads are not present, it is difficult to get sem_wait() or sem_timedwait() to do the right thing (since pthread_cond_timedwait() and pthread_cond_wait() are stubs in libc and just return immediately).

| | | | | | | | | | | | | | | gethostname()'s old and new signatures without requiring a library bump. Note that programs which called gethostname() with a negative argument were already broken, since the same type conversion was done by the old implementation. Add a note in the Makefile so that whoever next bumps the libc revision will delete the kluge at the same time (as it will no longer be necessary). This is only operative on 64-bit platforms.

* Change gethostname() to set errno to ENAMETOOLONG instead of ENOMEMGarrett Wollman2003-08-192-18/+51
| | | | | | | | | | | | | | | | | | | | | | | | | | | | when the buffer is not long enough to hold the current host name. POSIX does not standardize error returns for gethostname(), so it doesn't matter which one we use, but ENAMETOOLONG is at least a little more intuitive, and mi suggests the existence of prior art. I've been running with this change for a while on my home machine with no effect. At the same time, I've updated the prototype for gethostname() to use the correct standard type (size_t) for the namelen argument. All of the in-tree callers fall into one of the following categories: 1) Call perror() or equivalent when gethostname() fails. 2) Ignore gethostname()'s return value entirely, potentially resulting in data corruption if the buffer is too small. 3) Fall back to a (possibly sensible) default value if gethostname() fails. Many of the callers I examined shows signs of confusion about the correct sizing of the host name buffer. gethostname(3) now has more information about this, as well as updated standards information.

* Revert to using yp_order() to probe for master.paswd.by* maps andBill Paul2003-07-181-7/+14
| | | | | | | | | | | | | | | | | | don't probe the server at all for passwd.by* maps. This fixes interoperability with the Services For UNIX NIS server (which is really a front end to Captive^WActiveDirectory). This server incorrectly returns success for all YPPROC_MASTER requests, even for maps that don't exist, which makes it impossible to (ab)use it to probe for the existence of the master.passwd.by* maps. This is a little kludgey, but basically restores the original behavior of getpwent.c as it is in -stable, and works around both the lack of YPPROC_ORDER on NIS+ servers as well as the broken YPPROC_MASTER on Services For UNIX servers.
