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 Fortify state store instances was specific to aids due to outdated design decisions carried over from the ego rewrite.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	f796622c35	state: rename simple store implementation ... Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-12-19 11:48:48 +09:00
Ophestra Umiker	5d25bee786	fortify: remove systemd check ... This is no longer necessary as fortify no longer integrates with external user switchers. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-12-19 11:14:31 +09:00
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
Ophestra Umiker	7f29b37a32	proc: setup payload send ... Generic setup payload encoder adapted from fshim. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-12-18 17:20:01 +09:00

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.

Ophestra Umiker	38e92edb8e	system/wayland: integrate security-context-v1 ... Had to pass the sync fd through sys. The rest are just part of a standard Op. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-12-06 04:20:15 +09:00

Ophestra Umiker	9faf3b3596	app: validate username ... This value is used for passwd generation. Bad input can cause very confusing issues. This is not a security issue, however validation will improve user experience. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-11-19 21:01:41 +09:00
Ophestra Umiker	ae2628e57a	cmd/fshim/ipc: install signal handler on shim start ... Getting killed at this point will result in inconsistent state. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-11-18 13:33:46 +09:00
Ophestra Umiker	05b7dbf066	app: alternative inner home path ... Support binding home to an alternative path in the mount namespace. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-11-18 00:18:21 +09:00

Ophestra Umiker	df33123bd7	app: integrate fsu ... This removes the dependency on external user switchers like sudo/machinectl and decouples fortify user ids from the passwd database. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-11-16 21:19:45 +09:00
Ophestra Umiker	9a13b311ac	app/config: rename map_real_uid from use_real_uid ... This option only changes mapped uid in the user namespace. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-11-09 12:01:34 +09:00
Ophestra Umiker	3dfc1fcd56	app: support full /dev access ... Also moved /dev/fortify to /fortify since it is impossible to create new directories in /dev from the init namespace and bind mounting its contents has undesirable side effects.

Ophestra Umiker	fc25ac2523	app: separate auto etc from permissive defaults ... Populating /etc with symlinks is quite useful even outside the permissive defaults usage pattern. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-11-04 22:18:05 +09:00
Ophestra Umiker	d909b1190a	app/config: UseRealUID as true in template ... The template is based on a Chromium setup, which this workaround was created for. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-11-04 19:45:31 +09:00
Ophestra Umiker	d7df24c999	fmsg: drop messages when msgbuf is full during withhold ... Logging functions are not expected to block. This change fixes multiple hangs where more than 64 messages are produced during withhold. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-11-04 12:56:19 +09:00

Ophestra Umiker	af15b1c048	app: support mapping target uid as privileged uid in sandbox ... Chromium's D-Bus client implementation refuses to work when its getuid call returns a different value than what the D-Bus server is running as. The reason behind this is not fully understood, but this workaround is implemented to support chromium and electron apps. This is not used by default since it has many side effects that break many other programs, like SSH on NixOS. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-11-04 03:15:39 +09:00
Ophestra Umiker	7962681f4a	app: format mapped uid instead of real uid ... Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-11-04 00:49:32 +09:00
Ophestra Umiker	bfcce3ff75	system/dbus: buffer xdg-dbus-proxy messages ... Pointing xdg-dbus-proxy to stdout/stderr makes a huge mess. This change enables app to neatly print out prefixed xdg-dbus-proxy messages after output is resumed. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-11-03 03:07:02 +09:00
Ophestra Umiker	584732f80a	cmd: shim and init into separate binaries ... This change also fixes a deadlock when shim fails to connect and complete the setup. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-11-02 03:13:57 +09:00
Ophestra Umiker	431dc095e5	app/start: skip cleanup if shim is nil ... Shim is created before any system operation happens. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-10-28 14:21:15 +09:00
Ophestra Umiker	60e91b9b0f	shim: expose checkPid in constructor ... This will be supported soon when launching via fsu. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-10-28 00:02:55 +09:00
Ophestra Umiker	51e84ba8a5	system/dbus: compare sealed value by string ... Stringer method of dbus.Proxy returns a string representation of its args stream when sealed. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-10-27 12:09:34 +09:00
Ophestra Umiker	7df9d8d01d	system: move sd_booted implementation to os abstraction ... This implements lazy loading of the systemd marker (they are not accessed in init and shim) and ensures consistent behaviour when running with a stub.

Ophestra Umiker	c7b77d6e5e	fmsg: initialise dequeue prior to withhold/resume ... This fixes the hang on resume when no messages were ever printed. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-10-27 01:24:30 +09:00
Ophestra Umiker	1d6ea81205	shim: user switcher process management struct ... This change moves all user switcher and shim management to the shim package and withholds output while shim is alive. This also eliminated all exit scenarios where revert is skipped. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-10-27 00:46:15 +09:00
Ophestra Umiker	ae1a102882	fmsg: support temporarily withholding output ... Trying to print to a shared stdout is a terrible idea. This change makes it possible to withhold output for the lifetime of the sandbox. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-10-26 23:09:32 +09:00
Ophestra Umiker	093e99d062	app: separate nixos test cases from tests ... Test cases are very long, separating them improves editor performance. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-10-25 17:44:29 +09:00
Ophestra Umiker	ad7e389eee	app: test app permissive defaults sealing behaviour ... This test seals App against a deterministic os stub and checks the resulting sys and bwrap values against known correct ones. The effects of sys and bwrap on the OS and sandbox is deterministic and tested in their own respective packages. Signed-off-by: Ophestra Umiker <cat@ophivana.moe>	2024-10-25 17:12:13 +09:00
