[RFC PATCH 10/21] kernel-hacking: Make DEBUG_{LIST,PLIST,SG,NOTIFIERS} non-debug options

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The CONFIG_DEBUG_{LIST,PLIST,SG,NOTIFIERS} options can provide useful
security hardening properties outside of debug scenarios. For example,
CVE-2019-2215 and CVE-2019-2025 are mitigated with negligible runtime
overhead by enabling CONFIG_DEBUG_LIST, and this option is already
enabled by default on many distributions:

https://googleprojectzero.blogspot.com/2019/11/bad-binder-android-in-wild-exploit.html

Rename these options across the tree so that the naming better reflects
their operation and remove the dependency on DEBUG_KERNEL.
