6420ca1b40 Add landlock runtime detection 
We cannot assume that landlock is enabled if we can compile it.
Even if it's enabled in the kernel it may still not be loaded.

We fill fallback to chroot/bind-mounts if we can.

If we can't (because path policies have landlock-specific options),
we can't do that either.

Closes: #21

98c76089de Handle new 5.16 syscall: futex_waitv 2021-12-27 14:26:37 +01:00

631980b775 Include linux/capability.h instead of sys/capability.h 
Some distros put sys/capability.h into libcap-dev or
similiar, which is a bit unforunate, we don't need
libcap-dev or anything like that.

Since we anyway only used the capget()/capset(), we can
just define a simple wrapper and call the syscall directly
and therefore avoid above mentioned issue.

b469a82eec pledge: Allow NO_NEW_PRIVS prctls 
Retreiving it does no harm. It cannot be unset once set, thus
no harm in allowing to set it either.

6711b394d9 pledge: Add EXILE_SYSCALL_PLEDGE_SECCOMP_INSTALL to allow adding further seccomp filters 2021-12-27 12:35:54 +01:00
Albert S
9abbc7510c Introduce exile_create_policy(): Creates an clean/empty policy. 
exile_create_policy() Creates an empty policy that can be
used by the exile.h API.

exile_init_policy() sets opinionated default values.

7115ef8b4d Begin an pledge()-like implementation 
This begins a pledge() implementation. This also
retires the previous syscall grouping approach,
as pledge() is the superior mechanism.

Squashed:
test: Begin basic pledge test
pledge: Begin EXILE_SYSCALL_PLEDGE_UNIX/EXILE_SYSCALL_PLEDGE_INET
test: Add pledge socket test
Introduce EXILE_SYSCALL_PLEDGE_DENY_ERROR, remove exile_policy->pledge_policy
pledge: Add PROT_EXEC

15a6850023 Begin low-level seccomp arg filter interface 
Squashed:
test: Adjust existing to new API with arg filters
test: Add tests for low-level seccomp args filter API
test: Add seccomp_filter_mixed()
test: Switch to syscall() everywhere
append_syscall_to_bpf(): Apply EXILE_SYSCALL_EXIT_BPF_NO_MATCH also for sock_filter.jt
