3700c495eb ("kbuild: Don't source kernel config"): kernel BUG at kernel/kallsyms.c:208!
by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
https://github.com/0day-ci/linux/commits/Richard-Weinberger/kbuild-Don-t-...
commit 3700c495eb174605765092bf54082e047de7dd7a
Author: Richard Weinberger <richard(a)nod.at>
AuthorDate: Mon Feb 19 10:22:45 2018 +0100
Commit: 0day robot <fengguang.wu(a)intel.com>
CommitDate: Mon Feb 19 21:21:23 2018 +0800
kbuild: Don't source kernel config
Don't source the kernel config file in shell scripts.
The config file is not a shell script and often imported from untrusted
sources.
What could possible go wrong? ;-)
Instead, read config file line by line and access config entries using a bash
array.
