2011-05-26rtlwifi: Use order 2 RX buffer allocation only if necessaryLarry Finger
Although a previous fix handles the kernel panics that result from failure to allocate a new RX buffer, memory fragmentation can be reduced if the amsdu_8k capability is disabled as new buffers need only be of O(0), not O(2).

2011-05-26rtlwifi: Fix kernel panic resulting from RX buffer allocation failureLarry Finger
To handle amsdu_8k capability, the PCI routine of this driver must allocate receive buffers of order 2. 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.

2011-05-26mwifiex: correct event header lengthYogesh Ashok Powar
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.

The bonding driver initializes some data structures only after its ndo_open routine is called. Among them is the initalization of the alb tx and rx hash locks. So if we add or remove a slave without first opening the bond master device, we run the risk of trying to lock/unlock a spinlock that has garbage for data in it, which results in our above softlock. Note that sometimes this works, because in many cases an unlocked spinlock has the raw_lock parameter initialized to zero (meaning that the kzalloc of the net_device private data is equivalent to calling spin_lock_init), but thats not true in all cases, and we aren't guaranteed that condition, so we need to pass the relevant spinlocks through the spin_lock_init function. Fix it by moving the spin_lock_init calls for the tx and rx hashtable locks to the ndo_init path, so they are ready for use by the bond_store_slaves path. Change notes: v2) Based on conversation with Jay and Nicolas it seems that the ability to enslave devices while the bond master is down should be safe to do. As such this is an outlier bug, and so instead we'll just initalize the errant spinlocks in the init path rather than the open path, solving the problem. We'll also remove the warnings about the bond being down during enslave operations, since it should be safe v3) Fix spelling error Signed-off-by: Neil Horman <nhorman@tuxdriver.com> Reported-by: jtluka@redhat.com CC: Jay Vosburgh <fubar@us.ibm.com> CC: Andy Gospodarek <andy@greyhouse.net> CC: nicolas.2p.debian@gmail.com CC: "David S.

2011-05-25via-velocity: don't annotate MAC registers as packedUlrich Hecht
On ARM, memory accesses through packed pointers behave in unexpected ways in GCC releases 4.3 and higher; see https://lkml.org/lkml/2011/2/2/163 for discussion. In this particular case, 32-bit I/O registers are accessed bytewise, causing incorrect setting of the DMA address registers which in turn leads to an error interrupt storm that brings the system to a halt. Since the mac_regs structure does not need any packing anyway, this patch simply removes the attribute to fix the issue. Signed-off-by: Ulrich Hecht <uli@suse.de> Signed-off-by: David S.

2011-05-23ehea: Fix multicast registration on semi-promiscuous modeBreno Leitao
Ehea will not register multicast groups in phyp if the physical interface is in promiscuous mode. But it should register if the logical port is in promiscuous mode, but the physical port is not. Ehea physical promiscuous mode is defined by ehea_port->promisc, while logical port is defined by IFF_PROMISC. So currently, if the user set the interface in promiscuous mode, IGMP will not be registred in PHYP, and PHYP will never pass the multicast packet to the logical port, which is bad So, this patch just fixes it, assuring that we register in phyp if the physical port is not on promiscuous mode.

2011-05-22Add appropriate <linux/prefetch.h> include for prefetch usersPaul Gortmaker
After discovering that wide use of prefetch on modern CPUs could be a net loss instead of a win, net drivers which were relying on the implicit inclusion of prefetch.h via the list headers showed up in the resulting cleanup fallout. Give them an explicit include via the following $0.02 script. ========================================= #!/bin/bash MANUAL="" for i in `git grep -l 'prefetch(.*)' .` ; do grep -q '<linux/prefetch.h>' $i if [ $? = 0 ] ; then continue fi ( echo '?^#include <linux/?a' echo '#include <linux/prefetch.h>' echo . echo w echo q ) | ed -s $i > /dev/null 2>&1 if [ $? != 0 ]; then echo $i needs manual fixup MANUAL="$i $MANUAL" fi done echo ------------------- 8\<---------------------- echo vi $MANUAL ========================================= Signed-off-by: Paul <paul.gortmaker@windriver.com> [ Fixed up some incorrect #include placements, and added some non-network drivers and the fib_trie.c case - Linus ] Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2011-05-22netpoll: disable netpoll when enslave a deviceAmerigo Wang
V3: rename NETDEV_ENSLAVE to NETDEV_JOIN Currently we do nothing when we enslave a net device which is running netconsole. Neil pointed out that we may get weird results in such case, so let's disable netpoll on the device being enslaved. I think it is too harsh to prevent the device being ensalved if it is running netconsole. By the way, this patch also removes the NETDEV_GOING_DOWN from netconsole netdev notifier, because netpoll will check if the device is running or not and we don't handle NETDEV_PRE_UP neither. This patch is based on net-next-2.6. Signed-off-by: WANG Cong <amwang@redhat.com> Cc: Neil Horman <nhorman@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Unicast frames between macvlan interfaces in bridge mode are not otherwise sent to network taps on the lowerdev (as all other macvlan frames are), so forward the frames to the receive queue of the lowerdev first.
