* staging-winbond: Kill directly reference of netdev->privWang Chen2008-12-08
| | | | | | | | | | | | This driver is not yet finished. At this time, we don't know how netdev be created and how private data be allocated. So, simply use netdev_priv() now and leave some temp comment. Compile test only. Signed-off-by: Wang Chen <wangchen@cn.fujitsu.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* staging-p80211: Kill directly reference of netdev->privWang Chen2008-12-07
| | | | | | | | | | | | | | | | | In this driver, netdev's private data is wlandevice_t. And the wlandev(type of wlandevice_t) is exist before netdev be allocated. So use netdev->ml_priv to point to the private data. I am not sure whether I should consider the kernel version older than 2.3.38. Because in those kernels, netdevice_t is "structure dev" instead of "structure net_device" and of course "dev->ml_priv" will cause compile error. But before my patch, in function wlan_setup(), there is a ether_setup(net_device) which already broke kernels which older than 2.3.38.

* tcp: fix tso_should_defer in 64bitIlpo Järvinen2008-12-06
| | | | | | | | | | | | | | Since jiffies is unsigned long, the types get expanded into that and after long enough time the difference will therefore always be > 1 (and that probably happens near boot as well as iirc the first jiffies wrap is scheduler close after boot to find out problems related to that early).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Under my 2.6.28-rc6 sparc64, when associating to an AP through my zd1211rw device, I was seeing kernel log messages like (not exact output): Kernel unaligned access at TPC[10129b68] zd_mac_rx+0x144/0x32c [zd1211rw] For the zd1211rw module, on RX, the 80211 packet will be located after the PLCP header in the skb data buffer. The PLCP header being 5 bytes long, the 80211 header will start unaligned from an aligned skb buffer. As per Documentation/unaligned-memory-access.txt, we must replace the not unaligned() safe compare_ether_addr() with memcmp() to protect architectures that require alignment.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After fixing zd1211rw: use unaligned safe memcmp() in-place of compare_ether_addr(), I started to see kernel log messages detailing unaligned access: Kernel unaligned access at TPC[100f7f44] sta_info_get+0x24/0x68 [mac80211] As with the aforementioned patch, the unaligned access was eminating from a compare_ether_addr() call. Concerned that whilst it was safe to assume that unalignment was the norm for the zd1211rw, and take preventative measures, it may not be the case or acceptable to use the easy fix of changing the call to memcmp(). My research however indicated that it was OK to do this, as there are a few instances where memcmp() is the preferred mechanism for doing mac address comparisons throughout the module.

| | * ipw2200: fix netif_*_queue() removal regressionZhu Yi2008-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In "ipw2200: Call netif_*_queue() interfaces properly", netif_stop_queue() and netif_wake_queue() were removed with the reason "netif_carrier_{on,off}() handles starting and stopping packet flow into the driver". The patch also removes a valid condition check that ipw_tx_skb() cannot be called if device is not in STATUS_ASSOCIATED state. But netif_carrier_off() doesn't guarantee netdev->hard_start_xmit won't be called because linkwatch event is handled in a delayed workqueue. This caused a kernel oops reported by Frank Seidel: https://bugzilla.novell.com/show_bug.cgi?id=397390 This patch fixes the problem by moving the STATUS_ASSOCIATED check back to ipw_tx_skb(). It also adds a missing netif_carrier_off() call to ipw_disassociate().

| * | tcp: tcp_vegas ssthresh bug fixDoug Leith2008-12-04
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a bug in tcp_vegas.c. At the moment this code leaves ssthresh untouched. However, this means that the vegas congestion control algorithm is effectively unable to reduce cwnd below the ssthresh value (if the vegas update lowers the cwnd below ssthresh, then slow start is activated to raise it back up). One example where this matters is when during slow start cwnd overshoots the link capacity and a flow then exits slow start with ssthresh set to a value above where congestion avoidance would like to adjust it.

| * tcp: make urg+gso work for real this timeIlpo Järvinen2008-12-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I should have noticed this earlier... :-) The previous solution to URG+GSO/TSO will cause SACK block tcp_fragment to do zig-zig patterns, or even worse, a steep downward slope into packet counting because each skb pcount would be truncated to pcount of 2 and then the following fragments of the later portion would restore the window again. Basically this reverts "tcp: Do not use TSO/GSO when there is urgent data" (33cf71cee1). It also removes some unnecessary code from tcp_current_mss that didn't work as intented either (could be that something was changed down the road, or it might have been broken since the dawn of time) because it only works once urg is already written while this bug shows up starting from ~64k before the urg point. The retransmissions already are split to mss sized chunks, so only new data sending paths need splitting in case they have a segment otherwise suitable for gso/tso. The actually check can be improved to be more narrow but since this is late -rc already, I'll postpone thinking the more fine-grained things.

Besides, just removing the controllers that where added on module load time and not those that were added later via b1isa_add_card() is wrong too - the place where all added cards are found is isa_dev[]. relevant dmesg lines: [ 0.000000] Linux version 2.6.27.4 (w@shubashi) (gcc version 4.3.2 (Debian 4.3.2-1) ) #3 Thu Oct 30 16:49:03 CET 2008 [ 67.403555] CAPI Subsystem Rev 1.1.2.8 [ 68.529154] capifs: Rev 1.1.2.3 [ 68.563292] capi20: Rev 1.1.2.7: started up with major 68 (middleware+capifs) [ 77.026936] b1: revision 1.1.2.2 [ 77.049992] b1isa: revision 1.1.2.3 [ 77.722655] kcapi: Controller [001]: b1isa-340 attached [ 77.722671] b1isa: AVM B1 ISA at i/o 0x340, irq 5, revision 255 [ 81.272669] b1isa-340: card 1 "B1" ready.

This fix has a minimum (but user visible) impact on the CAN filter API and therefore the CAN version is set to a new date. Indeed the 'old' API is still working as-is. But when now setting CAN_(EFF|RTR)_FLAG in can_filter.can_mask you might get less traffic than before - but still the stuff that you expected to get for your defined filter ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bnx2 chips do not support per MSI vector masking. On 5706/5708, new MSI address/data are stored only when the MSI enable bit is toggled. As a result, SMP affinity no longer works in the latest kernel. A more serious problem is that the driver will no longer receive interrupts when the MSI receiving CPU goes offline. The workaround in this patch only addresses the problem of CPU going offline. When that happens, the driver's timer function will detect that it is making no forward progress on pending interrupt events and will recover from it. Eric Dumazet reported the problem. We also found that if an interrupt is internally asserted while MSI and INTA are disabled, the chip will end up in the same state after MSI is re-enabled. The same workaround is needed for this problem. Signed-off-by: Michael Chan <mchan@broadcom.com> Tested-by: Eric Dumazet <dada1@cosmosbay.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Miller around a year ago, and the current situation is much worse that what it was back then. tcp_sacktag_one can be made a bit simpler by returning the new sacked (it can be achieved with a single variable though the previous code "caching" sacked into a local variable and therefore it is not exactly equal but the results will be the same). codiff on x86_64 tcp_sacktag_one | -15 tcp_shifted_skb | -50 tcp_match_skb_to_sack | -1 tcp_sacktag_walk | -64 tcp_sacktag_write_queue | -59 tcp_urg | +1 tcp_event_data_recv | -1 7 functions changed, 1 bytes added, 190 bytes removed, diff: -189 Signed-off-by: Ilpo Järvinen <ilpo.jarvinen@helsinki.fi> Signed-off-by: David S.

| * | iwl3945 : Fix a-band association for passive channelsAbhijeet Kolekar2008-12-05

This enables sending of direct probes on passive channels, as long as some traffic is detected on that channel. This improves the scanning for hidden SSIDs in A-band,which is all passive channels. This patch fixes the bug no 1748. http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1748 2) This fix will only work with uCode version 15.28.2.8 and above. Prior versions of uCode would work only if we heard the traffic within active dwell time, which is much shorter than passive dwell time and is shorter than typical beacon periods. This patch also provids full active dwell time even if we hear traffic late in passive dwell. 3) uCode API version is incremented to 2.

The API version number is stored as part of the filename, we first try to load the most recent firmware and progressively try lower versions. The API version is also read from the firmware self and stored as part of the iwl_priv structure. Only firmware that is supported by driver will be loaded. The version number read from firmware is compared to supported versions in the driver not the API version used as part of filename. An example using this new infrastrucure: if (IWL_UCODE_API(priv->ucode_ver) >= 2) { Driver interacts with Firmware API version >= 2. } else { Driver interacts with Firmware API version 1. } Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.
