In this case, it is possible for malloc to be left in an inconsistent state in the child. Our thread libraries, libpthread in particular, need to use malloc internally after a fork (in the child).

Bring in required TLI library routines to support this. Since we don't support TLI we've essentially copied what NetBSD has done, adding a thin layer to emulate direct the TLI calls into BSD socket calls. This is mostly from Sun's tirpc release that was made in 1994, however some fixes were backported from the 1999 release (supposedly only made available after this porting effort was underway). The submitter has agreed to continue on and bring us up to the 1999 release. Several key features are introduced with this update: Client calls are thread safe. (1999 code has server side thread safe) Updated, a more modern interface. Many userland updates were done to bring the code up to par with the recent RPC API. There is an update to the pthreads library, a function pthread_main_np() was added to emulate a function of Sun's threads library. While we're at it, bring in NetBSD's lockd, it's been far too long of a wait. New rpcbind(8) replaces portmap(8) (supporting communication over an authenticated Unix-domain socket, and by default only allowing set and unset requests over that channel). It's much more secure than the old portmapper. Umount(8), mountd(8), mount_nfs(8), nfsd(8) have also been upgraded to support TI-RPC and to support IPV6. Umount(8) is also fixed to unmount pathnames longer than 80 chars, which are currently truncated by the Kernel statfs structure.

* libc MT-safety, part 2.Daniel Eischen2001-02-112-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a lock to FILE. flockfile and friends are now implemented (for the most part) in libc. flockfile_debug is implemented in libc_r; I suppose it's about time to kill it but will do it in a future commit. Fix a potential deadlock in _fwalk in a threaded environment. A file flag (__SIGN) was added to stdio.h that, when set, tells _fwalk to ignore it in its walk. This seemed to be needed in refill.c because each file needs to be locked when flushing. Add a stub for pthread_self in libc. This is needed by flockfile which is allowed by POSIX to be recursive. Make fgetpos() error return value (-1) match man page. Remove recursive calls to locked functions (stdio); I think I've got them all, but I may have missed a couple. A few K&R -> ANSI conversions along with removal of a few instances of "register". $Id$ -> $FreeBSD$ in libc/stdio/rget.c Not objected to: -arch, a few months ago Notes: svn path=/head/; revision=72373
* Remove _THREAD_SAFE and make libc thread-safe by default byDaniel Eischen2001-01-243-2/+270
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | adding (weak definitions to) stubs for some of the pthread functions. If the threads library is linked in, the real pthread functions will pulled in. Use the following convention for system calls wrapped by the threads library: __sys_foo - actual system call _foo - weak definition to __sys_foo foo - weak definition to __sys_foo Change all libc uses of system calls wrapped by the threads library from foo to _foo. In order to define the prototypes for _foo(), we introduce namespace.h and un-namespace.h (suggested by bde). All files that need to reference these system calls, should include namespace.h before any standard includes, then include un-namespace.h after the standard includes and before any local includes. <db.h> is an exception and shouldn't be included in between namespace.h and un-namespace.h namespace.h will define foo to _foo, and un-namespace.h will undefine foo. Try to eliminate some of the recursive calls to MT-safe functions in libc/stdio in preparation for adding a mutex to FILE. We have recursive mutexes, but would like to avoid using them if possible. Remove uneeded includes of <errno.h> from a few files. Add $FreeBSD$ to a few files in order to pass commitprep. Approved by: -arch Notes: svn path=/head/; revision=71579
