d6aef3aa2c copy sigmask from parent process to child 2014-09-09 13:53:25 +09:00

19fa391d4f Implement vfork system call 
It's implemented by making it issue clone system call internally with
the arguments of (SIGCHLD, 0, 0, 0, 0). The feature in which the caller
of vfork blocks until the child issues exit/execve is not implemented.
Refer to #233.

6dd5407b5f Return error when no core is available 
clone returns -EAGAIN when there is no vacant core.
In addition, clone tries to use the next vacant hyper-threading
core instead of trying to use next vacant hyper-threading core
of the next vacant physical core.

0dd7a8deff Put AT_CLKTCK in ELF auxiliary vectors 
Put AT_CLKTCK in ELF auxiliary vectors because some functions
use the value as described below.
1. GLRO(dl_clktck) set by
   _dl_aux_init (in glibc/elf/dl-support.c)
   or
   _dl_sysdep_start (in elf/dl-sysdep.c)

2. GLRO(dl_clktck) is referenced by
__sysconf (in glibc/sysdeps/posix/sysconf.c)
   __getclktck
      (in glibc/sysdeps/unix/sysv/linux/getclktck.c)
profil (in glibc/sysdeps/posix/profil.c)
