# snap-seccomp version information:
# 627533ae604bd2eb86646b14b59f338ee25d4862 2.5.3 e96c43fe76b249e99e02e7ee97d074f17ed464207a45d0472d26d15138a88d7d bpf-actlog

# Description: Allows access to app-specific directories and basic runtime
#
# The default seccomp policy is default deny with an allowlist of allowed
# syscalls. The default policy is intended to be safe for any application to
# use and should be evaluated in conjunction with other security backends (eg
# AppArmor). For example, a few particularly problematic syscalls that are left
# out of the default policy are (non-exhaustive):
# - kexec_load
# - create_module, init_module, finit_module, delete_module (kernel modules)
# - name_to_handle_at (history of vulnerabilities)
# - open_by_handle_at (history of vulnerabilities)
# - ptrace (can be used to break out of sandbox with <4.8 kernels)
# - add_key, keyctl, request_key (kernel keyring)

# ioctl() mediation currently primarily relies on Linux capabilities as well as
# the initial syscall for the fd to pass to ioctl(). See 'man capabilities'
# and 'man ioctl_list'. TIOCSTI requires CAP_SYS_ADMIN but allows for faking
# input (man tty_ioctl), so we disallow it to prevent snaps plugging interfaces
# with 'capability sys_admin' from interfering with other snaps or the
# unconfined user's terminal.
# similarly, TIOCLINUX allows to fake input as well (man ioctl_console) so
# disallow that too
