Hello all,
Target runs a CentOS8 kernel with KASLR enabled.
I triggered a crash on it for training purpose with 'echo c >
/proc/sysrq-trigger'.
I analyze the produced dumpfile on another machine where I setup all sources and required
debuginfo packages.
So far, so good, the backtrace list is complete.
But I tried to match address to symbol, I have something like that (e.g. for
proc_reg_write() ):
crash> info address proc_reg_write
Symbol "proc_reg_write" is a function at address 0xffffffffa4099980.
crash> info symbol 0xffffffffa4099980
No symbol matches 0xffffffffa4099980.
Is there a more 'elegant' way to retrieve the symbol from address than to perform
an 'objdump' request on the vmlinux.debug binary ?
Have I missed an option for a command ?
Note: I get the same behavior with 'crash --kaslr auto' than with
'crash'.
Thanks.
Best regards,
Patrick Agrain
