Subject: [PATCH 4.19 093/125] serial: 8250: change lock order in serial8250_do_startup()
Date: Tue, 1 Sep 2020 17:10:48 +0200 [thread overview]
Message-ID: <20200901150939.156891276@linuxfoundation.org> (raw)
In-Reply-To: <20200901150934.576210879@linuxfoundation.org>
From: Sergey Senozhatsky <sergey.senozhatsky@gmail.com>
commit 205d300aea75623e1ae4aa43e0d265ab9cf195fd upstream.
We have a number of "uart.port->desc.lock vs desc.lock->uart.port"
lockdep reports coming from 8250 driver; this causes a bit of trouble
to people, so let's fix it.
The problem is reverse lock order in two different call paths:
chain #1:
serial8250_do_startup()
spin_lock_irqsave(&port->lock);
disable_irq_nosync(port->irq);
raw_spin_lock_irqsave(&desc->lock)
chain #2:
__report_bad_irq()
raw_spin_lock_irqsave(&desc->lock)
for_each_action_of_desc()
printk()
spin_lock_irqsave(&port->lock);
Fix this by changing the order of locks in serial8250_do_startup():
do disable_irq_nosync() first, which grabs desc->lock, and grab
uart->port after that, so that chain #1 and chain #2 have same lock
order.
