Ophestra	3c55fc8e86	proc/priv/shim: do not log bwrap args ... This message is very long and does not serve much real purpose. Remove it to de-clutter verbose messages. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-01-20 19:51:28 +09:00

Ophestra	7baca66a56	proc: remove duplicate compile-time fortify reference ... This is no longer needed since shim and init are now part of the main program. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-01-18 11:59:33 +09:00

Ophestra	16db3dabe2	internal: do PR_SET_PDEATHSIG once ... This prctl affects the entire process, doing it on every OS thread is pointless. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-01-17 23:08:46 +09:00
Ophestra	124743ffd3	app: expose single run method ... App is no longer just a simple [exec.Cmd] wrapper, so exposing these steps separately no longer makes sense and actually hinders proper error handling, cleanup and cancellation. This change removes the five-second wait when the shim dies before receiving the payload, and provides caller the ability to gracefully stop execution of the confined process.

Ophestra	562f5ed797	fst: hide sockets exposed via Filesystem ... This is mostly useful for permissive defaults. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-01-15 10:13:18 +09:00
Ophestra	6acd0d4e88	linux/std: handle fsu exit status 1 ... Printing "exit status 1" is confusing. This handles the ExitError and returns EACCES instead. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-01-01 21:34:57 +09:00

Ophestra	b9e2003d5b	app: ensure extra paths ... The primary use case for extra perms is app-specific state directories, which may or may not exist (first run of any app). Signed-off-by: Ophestra <cat@gensokyo.uk>	2024-12-28 14:07:49 +09:00

Ophestra Umiker	eae3034260	state: expose aids and use instance id as key ... Fortify state store instances was specific to aids due to outdated design decisions carried over from the ego rewrite. That no longer makes sense in the current application, so the interface now enables a single store object to manage all transient state.

Ophestra Umiker	f773c92411	system: prevent duplicate Wayland op ... Wayland is implemented as an Op to enforce dependency and cleanup, its implementation does not allow multiple instances on a single sys object, nor would doing that make any sense.
