This is important wrt the key flags as they are used during key clearing and if they are not set when the key is set the key cannot be cleared completely. This addresses the many occurences of the WARN found in iwl_set_tkip_dynamic_key_info() and tracked in http://www.kerneloops.org/searchweek.php?search=iwl_set_dynamic_key If calling iwl_set_tkip_dynamic_key_info()/iwl_remove_dynamic_key() pair a few times in a row will cause that we run out of key space. This is because the index stored in the key flags is used by iwl_remove_dynamic_key() to decide if it should remove the key. Unfortunately the key flags, and hence the key index is currently only set at the time the key is written to the device (in iwl_update_tkip_key()) and _not_ in iwl_set_tkip_dynamic_key_info().

| * | e1000: fix virtualization bugJesse Brandeburg2009-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | a recent fix to e1000 (commit 15b2bee2) caused KVM/QEMU/VMware based virtualized e1000 interfaces to begin failing when resetting. This is because the driver in a virtual environment doesn't get to run instructions *AT ALL* when an interrupt is asserted. The interrupt code runs immediately and this recent bug fix allows an interrupt to be possible when the interrupt handler will reject it (due to the new code), when being called from any path in the driver that holds the E1000_RESETTING flag. the driver should use the __E1000_DOWN flag instead of the __E1000_RESETTING flag to prevent interrupt execution while reconfiguring the hardware.

EEM is different from the Ethernet Control Model (ECM) currently supported by the "CDC Ethernet" driver. One key difference is that it doesn't require of USB interface alternate settings to manage interface state; some maldesigned hardware can't handle that part of USB. It also avoids a separate USB interface for control and status updates.

| * mv643xx_eth: 64bit mib counter read fixLennert Buytenhek2009-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On several mv643xx_eth hardware versions, the two 64bit mib counters for 'good octets received' and 'good octets sent' are actually 32bit counters, and reading from the upper half of the register has the same effect as reading from the lower half of the register: an atomic read-and-clear of the entire 32bit counter value. This can under heavy traffic occasionally lead to small numbers being added to the upper half of the 64bit mib counter even though no 32bit wrap has occured. Since we poll the mib counters at least every 30 seconds anyway, we might as well just skip the reads of the upper halves of the hardware counters without breaking the stats, which this patch does.

| * mv643xx_eth: OOM handling fixesLennert Buytenhek2009-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, when OOM occurs during rx ring refill, mv643xx_eth will get into an infinite loop, due to the refill function setting the OOM bit but not clearing the 'rx refill needed' bit for this queue, while the calling function (the NAPI poll handler) will call the refill function in a loop until the 'rx refill needed' bit goes off, without checking the OOM bit. This patch fixes this by checking the OOM bit in the NAPI poll handler before attempting to do rx refill. This means that once OOM occurs, we won't try to do any memory allocations again until the next invocation of the poll handler. While we're at it, change the OOM flag to be a single bit instead of one bit per receive queue since OOM is a system state rather than a per-queue state, and cancel the OOM timer on entry to the NAPI poll handler if it's running to prevent it from firing when we've already come out of OOM.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After experimenting with kexec with the last merges after 2.6.29, I've had some problems when probing e100. It would not read the eeprom. After some bisects, I realized this has been like that since forever (at least 2.6.18). The problem is that shutdown is doing the same thing that suspend does and puts the device in D3 state. I couldn't find a way to get the device back to a sane state in the probe function. So, based on some similar patches from Rafael J. Wysocki for e1000, e1000e, and ixgbe, I wrote this one for e100.

| * 8139too: fix HW initial flowJianjun kong2009-04-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While ifconfig eth0 up kernel calls open() of 8139 driver(8139too.c). In rtl8139_hw_start() of rtl8139_open(), 8139 driver enable RX before setting up the DMA buffer address. In this interval where RX was enabled and DMA buffer address is not yet set up, any incoming broadcast packet would be send to a strange physical address: 0x003e8800 which is the default value of DMA buffer address. Unfortunately, this address is used by Linux kernel. So kernel panics. This patch fix it by setting up DMA buffer address before RX enabled and everything is fine even under broadcast packets attack.

| * iwlwifi: DMA fixesReinette Chatre2009-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A few issues wrt DMA were uncovered when using the driver with swiotlb. - driver should not use memory after it has been mapped - iwl3945's RX queue management cannot use all of iwlagn because the size of the RX buffer is different. Revert back to using iwl3945 specific routines that map/unmap memory. - no need to "dma_syn_single_range_for_cpu" followed by pci_unmap_single, we can just call pci_unmap_single initially - only map the memory area that will be used by device. this is especially relevant to the mapping of iwl_cmd. we should not map the entire structure because the meta data at the beginning of structure contains the address to be used later for unmapping. If the address to be used for unmapping is stored in mapped data it creates a problem. - ensure that _if_ memory needs to be modified after it is mapped that we call _sync_single_for_cpu first, and then release it back to device with _sync_single_for_device - we mapped the wrong length of data for host commands, with mapped length differing with length provided to device, fix that.

| * iwlwifi: add debugging for TX pathReinette Chatre2009-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When debugging TX issues it is helpful to know the seq nr of the frame being transmitted. The seq nr is printed as part of ucode's log informing us which frame is being processed. Having this information printed in driver log makes it easy to match activities between driver and firmware. Also make possible to print TX flags directly. These are already printed as part of entire TX command, but having it printed directly in cpu format makes it easier to look at.

| * mwl8: fix build warning.Rami Rosen2009-04-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a build warning in mwl8.c. (Marvell TOPDOG wireless driver) The warning it fixes is: "large integer implicitly truncated to unsigned type." The rx_ctrl member of the mwl8k_rx_desc struct is 8 bit (__u8 ), whereas trying to assign it a 32 bit value (which is returned from cpu_to_le32()) causes the compiler to issue a truncation warning.
