* iwlwifi: fix suspend/resume and its usage of pci saved stateReinette Chatre2009-02-11
| | | | | | | | | | | | | | | | | | | | | | | | | Here we do two things: First, revert "iwlwifi: save PCI state before suspend, restore after resume". That misguided patch led to being unable to use iwlwifi devices after resume. Next, indicate to PCI driver that the saved PCI state is valid during suspend. We restore PCI state and enable the device when network interface is created, similarly PCI state is saved and the device is disabled when network interface is removed. Thus, when .suspend is called the PCI state is saved and device is disabled. This is the case even if an interface is never created as PCI state is saved and device disabled during .probe. PCI driver assumes PCI state is saved in .suspend. Saving the state at this time will save state of disabled device and thus cause problems during resume (resuming a disabled device). We thus indicate directly to PCI driver that current PCI saved state is valid.

* sunhme: Fix Quattro HME irq registration on proble failuresMeelis Roos2009-02-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the sunhme driver installs SBus Quattro interrupt handler when at least one HME card was initialized correctly and at least one Quattro card is present. This breaks when a Quattro card fails initialization for whatever reason - IRQ is registered and OOPS happens when it fires. The solution, as suggested by David Miller, was to keep track which cards of the Quattro bundles have been initialized, and request/free the Quattro IRQ only when all four devices have been successfully initialized. The patch only touches SBus initialization - PCI init already resets the card pointer to NULL on init failure. The patch has been tested on Sun E3500 with SBus and PCI single HME cards and one PCI Quattro HME card in a situation where any PCI card failed init when the SBus routines tried to init them by mistake. Additionally it replaces Quattro request_irq panic with error return - if this card fails to work, at least let the others work. Tested on E450 with PCI HME and PCI Quad HME.

* tun: Fix unicast filter overflowAlex Williamson2009-02-08
| | | | | | | | | | | | | | | | Tap devices can make use of a small MAC filter set via the TUNSETTXFILTER ioctl. The filter has a set of exact matches plus a hash for imperfect filtering of additional multicast addresses. The current code is unbalanced, adding unicast addresses to the multicast hash, but only checking the hash against multicast addresses. This results in the filter dropping unicast addresses that overflow the exact filter. The fix is simply to disable the filter by leaving count set to zero if we find non-multicast addresses after the exact match table is filled.

* 3c509: Fix resume from hibernation for PnP mode.Ondrej Zary2009-02-07
| | | | | | | | | | | | | | | | | | | | | | | From: Ondrej Zary <linux@rainbow-software.org> last year, I posted a patch which fixed hibernation on 3c509 cards. That was back in 2.6.24. It worked fine in 2.6.25. But then I stopped using hibernation (as it did not work with my new IT8212 RAID controller). Now I fixed it and noticed that 3c509 does not wake up properly anymore (in 2.6.28) - neither in PnP nor in ISA modes. ifconfig down/up makes the card work again in PnP mode. However, in ISA mode, ifconfig up ends with "No such device" error. Comparing the 3c509 driver between 2.6.25 and 2.6.28, there's only some statistics-related change. So the cause of the problem must be somewhere else. This patch makes the resume work in PnP mode, but it's still not enough for ISA mode. Signed-off-by: David S. Miller <davem@davemloft.net>
* sungem: Soft lockup in sungem on Netra AC200 when switching interface upIlkka Virta2009-02-07
| | | | | | | | | | | | | | | | | | | | | From: Ilkka Virta <itvirta@iki.fi> In the lockup situation the driver seems to go off in an eternal storm of interrupts right after calling request_irq(). It doesn't actually do anything interesting in the interrupt handler. Since connecting the link afterwards works, something later in initialization must fix this. Looking at gem_do_start() and gem_open(), it seems that the only thing done while opening the device after the request_irq(), is a call to napi_enable(). I don't know what the ordering requirements are for the initialization, but I boldly tried to move the napi_enable() call inside gem_do_start() before the link state is checked and interrupts subsequently enabled, and it seems to work for me. Doesn't even break anything too obvious... Signed-off-by: David S. Miller <davem@davemloft.net>

The process stays in endless loop in rtl8169_get_ethtool_stats. This is because these chips need to have receiver enabled (CmdRxEnb bit in ChipCmd register) that is cleared when the interface is going down. It's better to update statistics only when the interface is up and otherwise return copy of statistics grabbed when the interface was up (in rtl8169_close). It is interesting that PCI-E NICs (like 8168b/8111b...) are not affected. Signed-off-by: Ivan Vecera <ivecera@redhat.com> Acked-by: Francois Romieu <romieu@fr.zoreil.com> Signed-off-by: David S.

* | udp: Fix UDP short packet false positiveJesper Dangaard Brouer2009-02-05
| | | | | | | | | | | | | | | | | | | | | | | | | | The UDP header pointer assignment must happen after calling pskb_may_pull(). As pskb_may_pull() can potentially alter the SKB buffer. This was exposted by running multicast traffic through the NIU driver, as it won't prepull the protocol headers into the linear area on receive.
