From 0416605548766782acee60701b5c712e9b9e1bc2 Mon Sep 17 00:00:00 2001 From: Aleksander Morgado Date: Fri, 13 Feb 2015 14:51:02 +0100 Subject: hso: fix rx parsing logic when skb allocation fails 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. Signed-off-by: Aleksander Morgado Signed-off-by: David S.
