From 21bc7af6e5e684b44725b20f679e701e38ceef15 Mon Sep 17 00:00:00 2001 From: Yogesh Ashok Powar Date: Wed, 18 May 2011 12:02:03 -0700 Subject: mwifiex: correct event header length While decoding received event packet from firmware, 4 bytes of interface header are already removed unconditionally. So for handling event only 4 more bytes needs to be pulled. This is achieved by changing event header length to 4. Almost all the events, except BA stream related and AMSDU aggregation control events, do not have the payload in their event skb. Such events handling depends only on the event ID. This event ID is the first four bytes of the event skb, which is copied to a separate variable before pulling the skb header. Hence event handling worked only for those events that didn't have payload in event skb. This patch fixes the broken event path of the events with payload in their event skb without harming existing working event path for the events without payload.

Since the memory was just kzalloc'ed, the check was always failing and SSID with over 32 characters were allowed to go through. This was causing a buffer overflow when copying the actual SSID to the proper place. This bug has been there since 2.6.29-rc4.

Under heavy load, this causes fragmentation of memory. The present code releases the current buffer before checking to see if a new one is availble. Recovery from allocation failures is not possible, which results in kernel panics. The fix is to reorder the code to check that a new buffer can be allocated before the old one is released. If not possible, the received frame is dropped and the old one is reused. Without this change, it is impossible to transfer a 2 GB file without a kernel panic.
