Subject: Coverity: can_rx_offload_irq_offload_timestamp(): Resource leaks
Date: Mon, 11 Nov 2019 17:35:25 -0800	[thread overview]
Message-ID: <201911111735.C0D6AFBDB@keescook> (raw)

Hello!

This is an experimental automated report about issues detected by Coverity
from a scan of next-20191108 as part of the linux-next weekly scan project:
https://scan.coverity.com/projects/linux-next-weekly-scan

You're getting this email because you were associated with the identified
lines of code (noted below) that were touched by recent commits:

c2a9f74c9d18 ("can: rx-offload: can_rx_offload_irq_offload_timestamp(): continue on error")

Coverity reported the following:

*** CID 1487846:  Resource leaks  (RESOURCE_LEAK)
/drivers/net/can/rx-offload.c: 219 in can_rx_offload_irq_offload_timestamp()
213
214     		if (!(pending & BIT_ULL(i)))
215     			continue;
216
217     		skb = can_rx_offload_offload_one(offload, i);
218     		if (IS_ERR_OR_NULL(skb))
vvv     CID 1487846:  Resource leaks  (RESOURCE_LEAK)
vvv     Variable "skb" going out of scope leaks the storage it points to.
219     			continue;
220
221     		__skb_queue_add_sort(&skb_queue, skb, can_rx_offload_compare);
222     	}
223
224     	if (!skb_queue_empty(&skb_queue)) {

If this is a false positive, please let us know so we can mark it as
such, or teach the Coverity rules to be smarter. If not, please make
sure fixes get into linux-next. :) For patches fixing this, please
include these lines (but double-check the "Fixes" first):
