deischen 2004-09-26 06:50:15 UTC FreeBSD src repository Modified files: lib/libpthread pthread.map lib/libpthread/thread Makefile.inc Added files: lib/libpthread/thread thr_execve.c Log: Add a wrapper for execve(). The exec'd process must be started with the signal mask and pending signals of the calling thread. These are stored in userland in libpthread. There is a small race condition in this patch which could cause problems if a signal arrives after setting the (kernel) signal mask and before exec'ing. The thread's set of pending signals also are not yet installed in the exec'd process. Both of these will be corrected with the addition of a special syscall.
