[opensuse-factory] [Tumbleweed] nmap: Illegal instruction
I've just installed nmap to test the ciphersuites offered by some webservers and the RPM install failed with an illegal instruction. That went away after several retries. When I now use nmpa I see sporadic "Illegal instruction" failures right after starting nmap. Re-starting the same command always succeeds. model name : Intel(R) Xeon(R) CPU E3-1225 v3 @ 3.20GHz stepping : 3 microcode : 0x1c flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx pdpe1gb rdtscp lm constant_tsc arch_perfmon pebs bts rep_good nopl xtopology nonstop_tsc aperfmperf eagerfpu pni pclmulqdq dtes64 monitor ds_cpl vmx smx est tm2 ssse3 fma cx16 xtpr pdcm pcid sse4_1 sse4_2 x2apic movbe popcnt tsc_deadline_timer aes xsave avx f16c rdrand lahf_lm abm ida arat epb pln pts dtherm tpr_shadow vnmi flexpriority ept vpid fsgsbase tsc_adjust bmi1 avx2 smep bmi2 erms invpcid xsaveopt (BTW, ht is disabled for this CPU, even though it's reported that some batch escaped with the HT feature not fused off).

Some BIOSes have a bug with the RDRAND instruction in which the machine incompletely disables it.the OS sees it enabled but any use causes illegal instruction. you will hit it for sure when trying to test something that requires openSSL. But I am not sure this is the issue you are hitting as no data on what the illegal instruction actually is. -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

It would help to $ gdb --args nmap --nmap_parameters (gdb) run <CRASH> (gdb) x/i $pc -- js suse labs -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

At the moment I can't reproduce it. The one thing I did differently yesterday was that I've had the machine on suspend to RAM for a considerable while.

to be honest, I'd leave the system running for several hours (or days) testing your RAM using memtest86+

I already did that before I set up the machine and it was passing with flying colors. Again, doing the same things as yesterday just works now (including re-installing nmap) and the only difference is the suspend-to-RAM cycle(s). Can't test this more deeply in the next few days, sorry.

32 bit? There was an illegal instruction bug on 13.1 32 bit, that triggered on suspend or hibernation. - -- Cheers / Saludos, Carlos E. R.

Today I've put the machine into suspend-to-RAM again for some time and while nmpa works I get illegal instruction traps from zypper this time around. As usual, retrying the command succeeds. I've since updated the kernel to 3.17.4. I have to conclude that suspend-to-RAM is somehow broken either for the 3.17 kernel (since it was a new install I've not have had an older kernel on ther) or for the machine (a Dell T20).

This problem has not reappeared with later kernel versions, so I'm thinking it was a problem with re-initialization of the CPU after the suspend.
