Looks much better, thanks! I think the only pending issue is discussing
the relationship of memory.oom_kill_all_tasks with /proc/pid/oom_score_adj

Hi,

A landlocked process has less privileges than a non-landlocked process
and must then be subject to additional restrictions when manipulating

target process, a landlocked process must have a subset of the target
process' rules.

Add a basic sandbox tool to create a process isolated from some part of
the system. This sandbox create a read-only environment. It is only
allowed to write to a character device such as a TTY:
# :> X
# echo $?
0
# ./samples/bpf/landlock1 /bin/sh -i
Launching a new sandboxed process.

This documentation can be built with the Sphinx framework.

The seccomp(2) syscall can be used by a task to apply a Landlock rule to
itself. As a seccomp filter, a Landlock rule is enforced for the current

Things have been pretty calm, and rc6 is out there. Nothing
particular really stands out - it all looks normal, with just under
half of the patch being drivers (networking stands out, but there's

being arch updates, and the rest is

When registering the rtc device to be used to handle alarm timers,
get_device is used to ensure the device doesn't go away but the module can
still be unloaded. Call try_module_get to ensure the rtc driver will not go
away.
