From Bugzilla Helper: User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Linux 2.4.18-14 i686) Opera 7.11 [en] Description of problem: RPC server and client programs built on i686 platform. When these programs were on RH7.2 ia64 m/c the server program fails on the rpc call 'pmap_unset' with the error "__get_myaddress: ioctl: No such device". The the rpc function "get_myaddress" fails with the same error. When this program is run through strace it was found that the failure was due to the ioctl call ioctl(3, SIOCGIFFLAGS, 0xbfffd908) = -1 ENODEV (No such device) HOWEVER the same program when built as a 64 bit application the problem does not occur. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.Write a program with calls to pmap_unset or get_myaddress 2.Build this program on a 32 bit machine 3.Run this application on a ia64 machine with RH 7.2 installed The applications fails with eror _get_myaddress: ioctl: No such device Actual Results: The applications fails with eror _get_myaddress: ioctl: No such device Expected Results: The error should not be seen. Additional info:
RHL 7.2 is not supported anymore. Furthermore that sounds like 32-bit syscall support problem on the kernel side, not glibc.
