You must not include anything from asm/ or linux/ into a user mode program. You can use the definition as a basis to write your own. This is related to this upstream Frysk bug btw: http://sourceware.org/bugzilla/show_bug.cgi?id=3912 The bogus _syscallX macros were removed from the 2.6.18 kernel but the x86_64 maintainer sneaked them back in to 2.6.19. We should remove them again -- they are removed again from upstream. (This is a mass-update to all current FC6 kernel bugs in NEW state) Hello, I'm reviewing this bug list as part of the kernel bug triage project, an attempt to isolate current bugs in the Fedora kernel. http://fedoraproject.org/wiki/KernelBugTriage I am CC'ing myself to this bug, however this version of Fedora is no longer maintained. Please attempt to reproduce this bug with a current version of Fedora (presently Fedora 8). If the bug no longer exists, please close the bug or I'll do so in a few days if there is no further information lodged. Thanks for using Fedora! Per the previous comment in this bug, I am closing it as INSUFFICIENT_DATA, since no information has been lodged for over 30 days. Please re-open this bug or file a new one if you can provide the requested data, and thanks for filing the original report! |
Description of problem: /usr/include/asm-x86_64/unistd.h defines the _syscall6 macros using __syscall_return which is defined as follows: #define __syscall_return(type, res) \ do { \ if ((unsigned long)(res) >= (unsigned long)(-MAX_ERRNO)) { \ errno = -(res); \ res = -1; \ } \ return (type) (res); \ } while (0) MAX_ERRNO is not defined, nor is there any definition found in any other public header. This means that programs that have to use the _syscall macros directly because they cannot use the glibc syscall() function now cannot compile anymore unless they define MAX_ERRNO themselves (looking at the kernel sources it seems the correct definition on x86_64 is 4095, which was also the value used pre 2.6.19).
