From e7ad26ee3cb74e61d0637c888f24dd478d77af58 Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Mon, 22 Aug 2022 11:04:47 +0200 Subject: alpha: Fix generic brk system call emulation in __brk_call (bug 29490) The kernel special-cases the zero argument for alpha brk, and we can use that to restore the generic Linux error handling behavior. Fixes commit b57ab258c1140bc45464b4b9908713e3e0ee35aa ("Linux: Introduce __brk_call for invoking the brk system call"). --- sysdeps/unix/sysv/linux/alpha/brk_call.h | 7 +++---- 1 file changed, 3 insertions(+), 4 deletions(-) (limited to 'sysdeps/unix/sysv/linux/alpha') diff --git a/sysdeps/unix/sysv/linux/alpha/brk_call.h b/sysdeps/unix/sysv/linux/alpha/brk_call.h index b8088cf13f..0b851b6c86 100644 --- a/sysdeps/unix/sysv/linux/alpha/brk_call.h +++ b/sysdeps/unix/sysv/linux/alpha/brk_call.h @@ -21,8 +21,7 @@ __brk_call (void *addr) { unsigned long int result = INTERNAL_SYSCALL_CALL (brk, addr); if (result == -ENOMEM) - /* Mimic the default error reporting behavior. */ - return addr; - else - return (void *) result; + /* Mimic the generic error reporting behavior. */ + result = INTERNAL_SYSCALL_CALL (brk, 0); + return (void *) result; } -- cgit 1.4.1
