linux-stable.git/drivers/macintosh, branch v5.7.7 Linux kernel stable tree drivers/macintosh: Fix memleak in windfarm_pm112 driver 2020-06-22T07:33:06+00:00 Michael Ellerman mpe@ellerman.id.au 2020-04-23T06:00:38+00:00 56b57cb7a3da57c6d3c87a040a0a3da42ae664b3 commit 93900337b9ac2f4eca427eff6d187be2dc3b5551 upstream. create_cpu_loop() calls smu_sat_get_sdb_partition() which does kmalloc() and returns the allocated buffer.

commit 93900337b9ac2f4eca427eff6d187be2dc3b5551 upstream.

create_cpu_loop() calls smu_sat_get_sdb_partition() which does
kmalloc() and returns the allocated buffer. In fact it's called twice,
and neither buffer is freed.

This results in a memory leak as reported by Erhard:

Those machines had the sensors described in their DT, too, so they didn't need manual creation of the sensor devices. The old code worked, though, because manual creation came first. Creation of DT devices then failed later and caused error logs, but the sensors worked nonetheless because of the manually created devices. When removing attach_adaper, manual creation now comes later and loses the race. The sensor devices were already registered via DT, yet with another binding, so the driver could not be bound to it. This fix refactors the code to remove the race and only manually creates devices if there are no DT nodes present. Also, the DT binding is updated to match both, the DT and manually created devices. Because we don't know which device creation will be used at runtime, the code to start the kthread is moved to do_probe() which will be called by both methods.

The most notable change is DEFINE_SHOW_ATTRIBUTE macro split in
seq_file.h.

Conversion rule is:

	llseek		=> proc_lseek
	unlocked_ioctl	=> proc_ioctl

	xxx		=> proc_xxx

	delete ".owner = THIS_MODULE" line
