ipmi:msghandler: Fix potential memory corruption in ipmi_create_user()

2025-05-07T22:25:48Z

The "intf" list iterator is an invalid pointer if the correct "intf->intf_num" is not found. Calling atomic_dec(&intf->nr_users) on and invalid pointer will lead to memory corruption. We don't really need to call atomic_dec() if we haven't called atomic_add_return() so update the if (intf->in_shutdown) path as well.

ipmi:msghandler: Export and fix panic messaging capability

2025-05-07T22:25:48Z

Don't have the other users that do things at panic time (the watchdog) do all this themselves, provide a function to do it. Also, with the new design where most stuff happens at thread context, a few things needed to be fixed to avoid doing locking in a panic context. Signed-off-by: Corey Minyard

ipmi:ssif: Fix a shutdown race

2025-05-07T22:25:48Z

It was possible for the SSIF thread to stop and quit before the kthread_stop() call because ssif->stopping was set before the stop. So only exit the SSIF thread is kthread_should_stop() returns true. There is no need to wake the thread, as the wait will be interrupted by kthread_stop(). Signed-off-by: Corey Minyard

ipmi:msghandler: Don't deliver messages to deleted users

2025-05-07T22:25:48Z

ipmi:si: Rework startup of IPMI devices

2025-05-07T22:25:48Z

It is possible in some situations that IPMI devices won't get started up properly. This change makes it so all non-duplicate devices will get started up. Signed-off-by: Corey Minyard

ipmi:msghandler: Add a error return from unhandle LAN cmds

2025-05-07T22:25:48Z

If we get a command from a LAN channel, return an error instead of just throwing it away. Signed-off-by: Corey Minyard

ipmi:msghandler: Shut down lower layer first at unregister

2025-05-07T22:25:48Z

This makes sure any outstanding messages are returned to the user before the interface is cleaned up. Signed-off-by: Corey Minyard
