ipmi: Use dev_warn_ratelimited() for incorrect message warnings

2025-07-10T12:59:43Z

During BMC firmware upgrades on live systems, the ipmi_msghandler generates excessive "BMC returned incorrect response" warnings while the BMC is temporarily offline. This can flood system logs in large deployments. Replace dev_warn() with dev_warn_ratelimited() to throttle these warnings and prevent log spam during BMC maintenance operations.

char: ipmi: remove redundant variable 'type' and check

2025-07-08T17:15:44Z

The variable 'type' is assigned the value SI_INVALID which is zero and later checks of 'type' is non-zero (which is always false). The variable is not referenced anywhere else, so it is redundant and so is the check, so remove these.

ipmi: Fix strcpy source and destination the same

2025-06-14T00:06:26Z

The source and destination of some strcpy operations was the same. Split out the part of the operations that needed to be done for those particular calls so the unnecessary copy wasn't done.

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:watchdog: Use the new interface for panic messages

It's available, remove all the duplicate code. Signed-off-by: Corey Minyard

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
