From mboxrd@z Thu Jan 1 00:00:00 1970 From: Aleksander Morgado Subject: [PATCH] hso: fix rx parsing logic when skb allocation fails Date: Fri, 13 Feb 2015 14:51:02 +0100 Message-ID: <1423835462-3454-1-git-send-email-aleksander@aleksander.es> Cc: j.dumon-x9gZzRpC1QbQT0dZR+AlfA@public.gmane.org, Aleksander Morgado To: linux-usb-u79uwXL29TY76Z2rM5mHXA@public.gmane.org, netdev-u79uwXL29TY76Z2rM5mHXA@public.gmane.org Return-path: Sender: linux-usb-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-Id: netdev.vger.kernel.org If skb allocation fails once the IP header has been received, the rx state is being set to WAIT_SYNC. The logic, though, shouldn't directly return, as the buffer may contain a full packet, and therefore the WAIT_SYNC state needs to be processed (resetting state to WAIT_IP, clearing rx_buf_size and re-initializing rx_buf_missing). So, just let the while loop continue so that in the next iteration the WAIT_SYNC state cleanly stops the loop. The WAIT_SYNC processing will be done just after that, only if the end of packet is flagged.
