When compiling Linux kernel with -fcf-protection=branch to enable x86
Indiret Branch Tracking (IBT), ENDBR is added to all global functions.
This creates more "legal" forward edges than necessary. -mmanual-endbr
provides a way to insert ENDBR instruction at function entry only via
the 'cf_check' f
When compiling Linux kernel with -fcf-protection=branch to enable x86
Indiret Branch Tracking (IBT), ENDBR is added to all global functions.
This creates more "legal" forward edges than necessary. -mmanual-endbr
provides a way to insert ENDBR instruction at function entry only via
the 'cf_check' f
