* Allocate red zone and stack space together and then split red zone fromdavidxu2004-10-061-7/+17
| | | | | allocated space, orignal code left red zone unallocated, but those space can be allocated by user code, and result was providing no protection.
* Respect POSIX specification, a value return from pthread_attr_getguardsizedavidxu2003-09-141-8/+18
| | | | | | | | | should be a value past to pthread_attr_setguardsize, not a rounded up value. Also fix a stack size matching bug in thr_stack.c, now stack matching code uses number of pages but not bytes length to match stack size, so for example, size 512 bytes and size 513 bytes should both match 1 page stack size.

The ability to create more than 1 KSE via pthread_setconcurrency() is in the works as well as support for PTHREAD_SCOPE_SYSTEM threads. Those should come shortly. There are still some known issues which davidxu and I are working on, but it'll make it easier for us by committing what we have. This library now passes all of the ACE tests that libc_r passes with the exception of one. It also seems to work OK with KDE including konqueror, kwrite, etc. I haven't been able to get mozilla to run due to lack of java plugin, so I'd be interested to see how it works with that.

* Make libc_r check the kern.usrstack sysctl instead of using internalpeter2001-10-261-3/+5
| | | | | | | kernel #defines to figure out where the stack is located. This stops libc_r from exploding when the kernel is compiled with a different KVM size. IMHO this is all kinda bogus, it would be better to just check %esp and work from that.

be malloc()ed, but they are now allocated using mmap(), just as the default-size stacks are. A separate cache of stacks is kept for non-default-size stacks. Collaboration with: deischen
