From db54f488ee24b14027c485e0005950dfdd5ef885 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Tue, 8 Jul 2003 03:40:49 +0000 Subject: Update. 2003-07-07 Ulrich Drepper * descr.h (struct pthread): Add pid field. * allocatestack.c (allocate_stack): Initialize pid field in descriptor. (__reclaim_stacks): Likewise. * init.c (sigcancel_handler): If __ASSUME_CORRECT_SI_PID is defined also check for PID of the signal source. (__pthread_initialize_minimal_internal): Also initialize pid field of initial thread's descriptor. * pthread_cancel.c: Use tgkill instead of tkill if possible. * sysdeps/unix/sysv/linux/fork.c: Likewise. * sysdeps/unix/sysv/linux/pt-raise.c: Likewise. * sysdeps/unix/sysv/linux/pthread_kill.c: Likewise. * sysdeps/unix/sysv/linux/raise.c: Likewise. --- sysdeps/unix/sysv/linux/kernel-features.h | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'sysdeps/unix') diff --git a/sysdeps/unix/sysv/linux/kernel-features.h b/sysdeps/unix/sysv/linux/kernel-features.h index 256e77b..4d19238 100644 --- a/sysdeps/unix/sysv/linux/kernel-features.h +++ b/sysdeps/unix/sysv/linux/kernel-features.h @@ -333,3 +333,15 @@ #if __LINUX_KERNEL_VERSION >= 132426 # define __ASSUME_AT_SECURE 1 #endif + +/* Starting with the 2.5.75 kernel the kernel fills in the correct value + in the si_pid field passed as part of the siginfo_t struct to signal + handlers. */ +#if __LINUX_KERNEL_VERSION >= 132427 +# define __ASSUME_CORRECT_SI_PID 1 +#endif + +/* The tgkill syscall was instroduced for i386 in 2.5.75. */ +#if __LINUX_KERNEL_VERSION >= 132427 && defined __i386__ +# define __ASSUME_TGKILL 1 +#endif -- cgit v1.1
