* Fix Yet Another 16 byte stack alignment bug. Thankfully, this one ispeter2004-03-312-10/+10
| | | | | | | | | | | solved by a simple 'make world'. The signalcontext function was going to the trouble of generating an even 16 byte alignment, but in fact it needed to be odd aligned to simulate the 8-byte return address having been pushed by the caller. This fixes yet another group of crashes in applications using libpthread. And yet again, it was my fault all along. While here, rename the duplicate internal ctx_wrapper() functions to makectx_wrapper() and sigctx_wrapper() so that traces aren't ambiguous.
* When a dynamic NSS module is built and linked against a threadnectar2004-03-303-23/+43
| | | | | | | | | | | | | library, it may pull in that thread library at run time. If the process started out single-threaded, this could cause attempts to release locks that do not exist. Guard against this possibility by checking __isthreaded before invoking thread primitives. A similar problem remains if the process is linked against one thread library, but the NSS module is linked against another. This can only be avoided by careful design of the NSS module.
