arcconf should check kernel config for legacy vsyscall support, it fails (segfault) if it's not present Reproducible: Always Steps to Reproduce: 1. compile kernel without vsyscall 2. install arcconf 3. run arcconf Actual Results: segfault Expected Results: program runs using vanilla 5.13 kernel on gcc 10.3
Hi. Are we talking here about 'CONFIG_X86_VSYSCALL_EMULATION'?
Hi. I am not able to reproduce. My System has disabled SYSVCALL. CONFIG_GENERIC_TIME_VSYSCALL=y # CONFIG_X86_VSYSCALL_EMULATION is not set # CONFIG_LEGACY_VSYSCALL_EMULATE is not set # CONFIG_LEGACY_VSYSCALL_XONLY is not set CONFIG_LEGACY_VSYSCALL_NONE=y 'arcconf' works perfectly fine with my Adaptec controller.
Closing, as I need more info.
I was able now to reproduce. Will add the check.
