Ophestra	3c80fd2b0f	app: defer system.I revert ... Just returning an error after a successful call of commit will leave garbage behind with no way for the caller to clean them. This change ensures revert is always called after successful commit with at least per-process state enabled. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-02-19 21:12:11 +09:00
Ophestra	ef81828e0c	app: remove share method ... This is yet another implementation detail from before system.I, getting rid of this vastly cuts down on redundant seal state. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-02-19 16:20:25 +09:00

Ophestra	dfd9467523	app: merge seal with sys ... The existence of the appSealSys struct was an implementation detail obsolete since system.I was integrated in 084cd84f36. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-02-19 01:36:29 +09:00

Ophestra	3ae2ab652e	system/wayland: sync file at caller specified address ... Storing this in sys is incredibly ugly: sys should be stateless and Ops must keep track of their state. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-02-17 13:24:17 +09:00
Ophestra	82a072f641	system/tmpfiles: implement private tmpfiles ... These are only available within the mount namespace and should significantly reduce attack surface. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-02-17 00:07:52 +09:00

Ophestra	e599b5583d	fmsg: implement suspend in writer ... This removes the requirement to call fmsg.Exit on every exit path, and enables direct use of the "log" package. However, fmsg.BeforeExit is still encouraged when possible to catch exit on suspended output. Signed-off-by: Ophestra <cat@gensokyo.uk>	2025-02-16 18:51:53 +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 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 Fortify state store instances was specific to aids due to outdated design decisions carried over from the ego rewrite.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	52f21a19f3	cmd/fshim: switch to setup pipe ... The socket-based approach is no longer necessary as fsu allows extra files and sudo compatibility is no longer relevant. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-12-18 19:39:25 +09:00
