Hi guys, I am following this[1] tutorial to install clang. However, I have made a small change in the configure command, and I am running it with '--enable-optimized' option to avoid the debug build. I am getting the errors (given at the end) related to *undeclared identifiers '__NR_*'*. Can someone please provide some input about how to tackle this issue? On my other machine, I followed the same guide[1] (without the --enable-optimized option), and everything built successfully.

It seems the mailing list has been broken for several days. It should now be temporarily fixed, but because the fix is temporary I can't promise it won't happen again until the permanent fix is available. Sorry for that. -hpa

Hello all, OpenSSL is using socket() calls (in FIPS mode) when handling ECDSA keys in privsep child. The socket() syscall is already denied in the seccomp filter, but in ppc64le kernel, it is implemented using socketcall() syscall, which is not denied yet (only SYS_SHUTDOWN is allowed) and therefore fails hard. See attached patch with proposed patch (deny is intentionally after allowing the

Hi HPA, Regarding the architecture un-supported system calls, I wrapped them with #ifndef __NR_<foo> .. #endif /* __NR_<foo> */ switches. I have already done that. But you also mentioned that in SYSCALLS.def all these calls should be present and marked with '?'.. Is that right..? Could you please give little more detail about the change you want. Thanks and Regards, Anil...

...ething missing in CentOS 5. The issue is that the _syscall0 macro is not defined anywhere. If I copy and paste the following definition for _syscall0 from a CentOS 4.4 system into the test program, it works just fine: #define _syscall0(type,name) \ type name(void) \ {\ return syscall(__NR_##name);\ } Has anyone else run into this problem?
