From e9a37242f9cca80496aa934158b7e366b8b419fa Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Thu, 23 May 2024 12:22:40 +0000 Subject: Update PIDFD_* constants for Linux 6.9 Linux 6.9 adds some more PIDFD_* constants. Add them to glibc's sys/pidfd.h, including updating comments that said FLAGS was reserved and must be 0, along with updating tst-pidfd-consts.py. Tested with build-many-glibcs.py. --- sysdeps/unix/sysv/linux/sys/pidfd.h | 15 +++++++-------- sysdeps/unix/sysv/linux/tst-pidfd-consts.py | 2 +- 2 files changed, 8 insertions(+), 9 deletions(-) diff --git a/sysdeps/unix/sysv/linux/sys/pidfd.h b/sysdeps/unix/sysv/linux/sys/pidfd.h index 1078322062..9f88d297e8 100644 --- a/sysdeps/unix/sysv/linux/sys/pidfd.h +++ b/sysdeps/unix/sysv/linux/sys/pidfd.h @@ -22,12 +22,14 @@ #include #define PIDFD_NONBLOCK O_NONBLOCK +#define PIDFD_THREAD O_EXCL -/* Returns a file descriptor that refers to the process PID.
