2008-05-13[netdrvr] sfc: Add phy_flash_cfg module parameter and implementationBen Hutchings
The 10Xpress PHY supports flash upgrades through MDIO, but needs to be put in upgrade mode at power-up. This adds a module parameter and other logic to support that. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-05-13[netdrvr] sfc: Add TSO supportBen Hutchings
The SFC4000 controller does not have hardware support for TSO, and the core GSO code incurs a high cost in allocating and freeing skbs. This TSO implementation uses lightweight packet header structures and is substantially faster. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-05-13ehea: Add DLPAR memory remove supportHannes Hering
The eHEA driver uses the recently modified walk_memory_resource for powerpc functionality to detect the memory layout. It further uses the memory hotplug notifiers to catch memory hotplug events. Signed-off-by: Hannes Hering <hering2@de.ibm.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-05-13myri10ge: fix the number of interrupt slotsBrice Goglin
Fix a long-standing bug/misunderstanding between the driver and the firmware. The size of the interrupt queue must be set to the number of rx slots (big + small), and it should never have been a tunable. Setting it too small results in chaos.

2008-05-13myri10ge: increase and fix handoff timeoutBrice Goglin
Increase the handoff timeout to 512ms so as to give the aeluros based NICs sufficient time to handoff without relying on the msleep() being sloppy, and accidentally sleeping way longer than the 20ms we specified in 20 separate 1ms sleeps.

2008-05-12mac80211: fix association with some APsHelmut Schaa
Some APs refuse association if the supported rates contained in the association request do not match its own supported rates. This patch introduces a new function which builds the intersection between the AP's supported rates and the client's supported rates to work around such problems. The same approach is already used in ipw2200 for example. Signed-off-by: Helmut Schaa <hschaa@suse.de> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-05-12zd1211rw: fix potential use-after-free bugJohannes Berg
zd_mac_tx_to_dev() could potentially free the skb, or hand it off to mac80211 which might free it. Hence, this code needs to get the usb pointer out of skb->cb before handing it off to that function.

2008-05-12Fix potential scheduling while atomic in mesh_path_add.Pavel Emelyanov
Calling synchronize_rcu() under write-lock-ed pathtbl_resize_lock may result in this warning (and other side effects). It looks safe just dropping this lock before calling synchronize_rcu. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-05-12Fix GFP_KERNEL allocation under read lock.Pavel Emelyanov
The mesh_path_add() read-locks the pathtbl_resize_lock and calls kmalloc with GFP_KERNEL mask. Fix it and move the endadd2 label lower. It should be _before_ the if() beyond, but it makes no sense for it being there, so I move it right after this if(). Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: John W.

2008-05-12mac80211: Don't encrypt beaconsIvo van Doorn
mac80211 should set the IEEE80211_TX_CTL_DO_NOT_ENCRYPT flag in tx_control structure to inform drivers not to encrypt the beacon. Drivers that only check for that flag before accessing the hw_key field, will otherwise cause a NULL pointer dereference since that field is not configured for beacons.

2008-05-12rt2x00: Clean up error handling of PCI queue DMA allocation.Ivo van Doorn
When, for some reason, the rt2x00pci module fails to allocate DMA memory for the queues, it tries to undo the complete initialization of the PCI device, including freeing of the irq. This results in the following error in dmesg, as the irq hadn't been requested yet: [ 78.123456] Trying to free already-free IRQ 17 Fix this by implementing proper error handling code, instead of just using the full uninitialization function.

2008-05-12rt2x00: Fix broken recover-on-error pathIvo van Doorn
During initialization the initialize() callback function in rt2x00pci and rt2x00usb will cleanup the mess they made. rt2x00lib shouldn't call uninitialize because the callback function already cleaned up _and_ the DEVICE_INITIALIZED isn't set which causes the rt2x00lib_uninitialize() to halt directly anyway. All that is required to be cleaned up by rt2x00lib is the queue, and that can be done by calling rt2x00queue_uninitialize() directly.

2008-05-12rt2x00: Don't use pskb_expand_head()Ivo van Doorn
rt2x00pci allocates DMA for descriptor and data, rt61pci doesn't use this for the beacon, but it can use the descriptor part as temporary buffer instead of using pskb_expand_head(). Using this temporary buffer is obviously much better then reallocating the skb buffer... At the same time we can set the data length for the beacon queue at 0, to make sure no DMA is allocated for data (but just for the descriptor).

2008-05-12mac80211: fix debugfs default key oopsJohannes Berg

2008-05-12fix irq flags in mac80211 codeSteven Rostedt
A file in the net/mac80211 directory uses "int" for flags. This can cause hard to find bugs on some architectures. This patch converts the flags to use "long" instead. This bug was discovered by doing an allyesconfig make on the -rt kernel where checks are done to ensure all flags are of size sizeof(long).

2008-05-12pppol2tp: Remove null pointer dereference.Julia Lawall
If session is NULL, it is not possible to access its name field. So I have split apart the printing of the error message to drop the printing of the name field in this case. The macro PRINTK actually only evaluates its arguments starting with the third one if the bitwise conjunction of the first two is non-zero. Normally, this conjunction would only be non-zero if debugging mode were turned on, but when session is NULL, the first argument in both the old and new code is -1, and thus the bitwise conjunction is true. Perhaps a different strategy is desired, such as using tunnel->debug, which session->debug is initialized to, but tunnel can also be NULL, so this does not completely solve the problem. This problem was found using the following semantic match (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression E, E1; identifier f; statement S1,S2,S3; @@ * if (E == NULL) { ... when != if (E == NULL) S1 else S2 when != E = E1 * E->f ... when any return ...; } else S3 // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S.

2008-05-12syncppp: Fix crashes.David S. Miller
The syncppp layer wants a mid-level netdev private pointer. It was using netdev->priv but that only worked by accident, and thus this scheme was broken when the device private allocation strategy changed. Add a proper mid-layer private pointer for uses like this, update syncppp and all users, and remove the HDLC_PPP broken tag from drivers/net/wan/Kconfig Signed-off-by: David S.
