seccomp: seccomp: add syscalls related to PKU in default policy

thaJeztah · thaJeztah · commit 19e8479837e1 · 2022-07-13T23:03:35.000+02:00
Add pkey_alloc(2), pkey_free(2) and pkey_mprotect(2) in seccomp default profile.
pkey_alloc(2), pkey_free(2) and pkey_mprotect(2) can only configure
the calling process's own memory, so they are existing "safe for everyone" syscalls.
