2008-02-08b43: Reject new firmware earlyMichael Buesch
(not in mainline, as it is not applicable.) We must reject new incompatible firmware early to avoid running into strange transmission failures. The current development tree supports newer firmware revisions. These revisions cause strange failures on the stable 2.6.24 kernel. Add a check to avoid confusing users a lot.

2008-02-08b43legacy: fix DMA slot resource leakageStefano Brivio
patch 8dd0100ce9511e52614ecd0a6587c13ce5769c8b in mainline. This fixes four resource leakages. In any error path we must deallocate the DMA frame slots we previously allocated by request_slot(). This is done by storing the ring pointers before doing any ring allocation and restoring the old pointers in case of an error. This patch by Michael Buesch has been ported to b43legacy.

2008-02-08b43legacy: drop packets we are not able to encryptStefano Brivio
patch 9eca9a8e81928685b4de00ecef83a7c13c340fc9 in mainline. We must drop any packets we are not able to encrypt. We must not send them unencrypted or with an all-zero-key (which basically is the same as unencrypted, from a security point of view). This might only trigger shortly after resume before mac80211 reassociated and reconfigured the keys. It is safe to drop these packets, as the association they belong to is not guaranteed anymore anyway. This is a security fix in the sense that it prevents information leakage.

2008-02-08b43legacy: fix suspend/resumeStefano Brivio
patch ada50731c0346bf900dc387edd3a6961297bf2d3 in mainline. This patch makes suspend/resume work with the b43legacy driver. We must not overwrite the MAC addresses in the init function, as this would also overwrite the MAC on resume. With an all-zero MAC the device firmware is not able to ACK any received packets anymore. Fix this by moving the initializion stuff that must be done on init but not on resume to the start function. Also zero out filter_flags to make sure we don't have some flags from a previous instance for a tiny timeframe until mac80211 reconfigures them.

Changeset 16b110c3fd760620b4a787db6ed512fe531ab1b5 (dmfe warning fix) bothed up the offsets read from the SROM so that it doesn't read the same datums it used to. The change made transformations like turning: "srom + 34" into "(__le32 *)srom + 34/4" which doesn't work because 4 does not divide evenly into 34 so we're using a different pointer offset than in the original code. I've changed theses cases in dmfe_parse_srom() to consistently use "(type *)(srom + offset)" preserving the offsets from the original code. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-01-20[NET]: rtnl_link: fix use-after-freePatrick McHardy
When unregistering the rtnl_link_ops, all existing devices using the ops are destroyed. With nested devices this may lead to a use-after-free despite the use of for_each_netdev_safe() in case the upper device is next in the device list and is destroyed by the NETDEV_UNREGISTER notifier. The easy fix is to restart scanning the device list after removing a device. Alternatively we could add new devices to the front of the list to avoid having dependant devices follow the device they depend on. A third option would be to only restart scanning if dev->iflink of the next device matches dev->ifindex of the current one. For now this seems like the safest solution. With this patch, the veth rtnl_link_ops unregistration can use rtnl_link_unregister() directly since it now also handles destruction of multiple devices at once.

2008-01-20[NET]: Fix interrupt semaphore corruption in Intel drivers.David S. Miller
Several of the Intel ethernet drivers keep an atomic counter used to manage when to actually hit the hardware with a disable or an enable. The way the net_rx_work() breakout logic works during a pending napi_disable() is that it simply unschedules the poll even if it still has work. This can potentially leave interrupts disabled, but that is OK because all of the drivers are about to disable interrupts anyways in all such code paths that do a napi_disable(). Unfortunately, this trips up the semaphore used here in the Intel drivers. If you hit this case, when you try to bring the interface back up it won't enable interrupts. A reload of the driver module fixes it of course. So what we do is make sure all the sequences now go: napi_disable(); atomic_set(&adapter->irq_sem, 0); *_irq_disable(); which makes sure the counter is always in the correct state.

2008-01-18bonding: fix locking in sysfs primary/active selectionJay Vosburgh
Fix the functions that store the primary and active slave options via sysfs to hold the correct locks in the correct order. The bond_change_active_slave and bond_select_active_slave functions both require rtnl, bond->lock for read and curr_slave_lock for write_bh, and no other locks. This is so that the lower level mode-specific functions (notably for balance-alb mode) can release locks down to just rtnl in order to call, e.g., dev_set_mac_address with the locks it expects (rtnl only).

2008-01-17ipg: fix Tx completion irq requestFrancois Romieu
The current logic will only request an ack for the first pending packet. No irq is triggered as soon as the CPU submits a few packets a bit quickly. Let's request an irq for every packet instead. Signed-off-by: Francois Romieu <romieu@fr.zoreil.com>

2008-01-17ipg: plug Tx completion leakFrancois Romieu
The Tx skb release could not free more than one skb per call. Add it to the fact that the xmit handler does not check for a queue full condition and you have a recipe to leak quickly. Let's release every pending Tx descriptor which has been given back to the host CPU by the network controller. The xmit handler suggests that it is done through the IPG_TFC_TFDDONE bit. Remove the former "curr" computing: it does not produce anything usable in its current form. Signed-off-by: Francois Romieu <romieu@fr.zoreil.com>

2008-01-17[NIU]: Fix 1G PHY link state handling.David S. Miller
The code in link_status_1g() computes the active speed and duplex but does not update the link config state with those values. As a result the link speed is not reported correctly and the XIF is not reprogrammed properly on link up events. Signed-off-by: David S. Miller <davem@davemloft.net>
