- actionfromafar 3y agoExploits, I guess is the concern.
- saagarjha 3y agoCode that uses syscalls that aren’t in libc but doesn’t want to have to drop to inline assembly?
- pizlonator 3y agoRight, so exploits.
- saagarjha 3y agoExploits are more than happy to drop to inline assembly.
- pizlonator 3y agoTheo already prevented you from making the syscall by using the trap instruction directly because of in kernel checking that you got to the kernel via the right point in libc.
