2008-07-21hdlcdrv: Fix CRC calculation.Micah Dowty
This is a trivial patch against the hdlcdrv module that fixes its CRC calculation. The finished CRC was overwriting the first two bytes of each packet rather than being appended to the end. I've tested this with 2.6.8 and 2.6.10-rc1, but hdlcdrv hasn't changed much recently so it should work with many other kernel versions.

Based upon a bug report by Alexander Beregalov and commentary from Ben Hutchings. These are totally unnecessary, in particular because this driver's ->hard_start_xmit() handler takes the same driver spinlock that the set-multicast-list handler uses. Signed-off-by: David S.

2008-07-21atl1: Do not wake queue before queue has been started.David S. Miller
Based upon a bug report by Alexey Dobriyan, the patch is also tested by him and confirmed to fix the problem. Packet flow during link state events should not be done by waking and stopping the TX queue anyways, that is handled transparently by netif_carrier_{on,off}(). So, remove the netif_{wake,stop}_queue() calls in the link check code, and add the necessary netif_start_queue() call to atl1_up(). Signed-off-by: David S. Miller <davem@davemloft.net>

2008-07-17netdev: netdev_priv() can now be sane again.David S. Miller

2008-07-17net: Use queue aware tests throughout.David S. Miller
This effectively "flips the switch" by making the core networking and multiqueue-aware drivers use the new TX multiqueue structures. Non-multiqueue drivers need no changes. The interfaces they use such as netif_stop_queue() degenerate into an operation on TX queue zero. So everything "just works" for them. Code that really wants to do "X" to all TX queues now invokes a routine that does so, such as netif_tx_wake_all_queues(), netif_tx_stop_all_queues(), etc. pktgen and netpoll required a little bit more surgery than the others. In particular the pktgen changes, whilst functional, could be largely improved. The initial check in pktgen_xmit() will sometimes check the wrong queue, which is mostly harmless. The thing to do is probably to invoke fill_packet() earlier. The bulk of the netpoll changes is to make the code operate solely on the TX queue indicated by by the SKB queue mapping. Setting of the SKB queue mapping is entirely confined inside of net/core/dev.c:dev_pick_tx(). If we end up needing any kind of special semantics (drops, for example) it will be implemented here. Finally, we now have a "real_num_tx_queues" which is where the driver indicates how many TX queues are actually active. With IGB changes from Jeff Kirsher. Signed-off-by: David S.

2008-07-17netdev: Allocate multiple queues for TX.David S. Miller
alloc_netdev_mq() now allocates an array of netdev_queue structures for TX, based upon the queue_count argument. Furthermore, all accesses to the TX queues are now vectored through the netdev_get_tx_queue() and netdev_for_each_tx_queue() interfaces. This makes it easy to grep the tree for all things that want to get to a TX queue of a net device. Problem spots which are not really multiqueue aware yet, and only work with one queue, can easily be spotted by grepping for all netdev_get_tx_queue() calls that pass in a zero index.

2008-07-17configfs: Allow ->make_item() and ->make_group() to return detailed errors.Joel Becker
The configfs operations ->make_item() and ->make_group() currently return a new item/group. A return of NULL signifies an error. Because of this, -ENOMEM is the only return code bubbled up the stack. Multiple folks have requested the ability to return specific error codes when these operations fail. This patch adds that ability by changing the ->make_item/group() ops to return ERR_PTR() values. These errors are bubbled up appropriately. NULL returns are changed to -ENOMEM for compatibility. Also updated are the in-kernel users of configfs.

After restore on ia64 xen domain, kernel panics as follows. This patch fixes it. union skb_entry assumes sizeof(link->skb, pointer) == sizeof(list->link, unsigned). However this isn't true on ia64. So make link type unsigned long. And introduced two accesor. kernel unaligned access to 0xe0000000000000bd, ip=0xa0000001004c2ca0 xenwatch[14]: error during unaligned kernel access -1 [1] Modules linked in: Pid: 14, CPU 0, comm: xenwatch psr : 0000101008422010 ifs : 8000000000000307 ip : [<a0000001004c2ca0>] Not tainted (2.6.26-rc4xen-ia64-dirty) ip is at dev_kfree_skb_irq+0x20/0x1a0 unat: 0000000000000000 pfs : 400000000000040b rsc : 0000000000000007 rnat: 0000000000000000 bsps: 0000000000000000 pr : 000000000000a941 ldrs: 0000000000000000 ccv : 0000000000000000 fpsr: 0009804c8a70433f csd : 0000000000000000 ssd : 0000000000000000 b0 : a0000001003efb70 b6 : a000000100070e40 b7 : a000000100070e40 f6 : 1003e000000fcb75352b1 f7 : 1003e000000000014ff97 f8 : 1003e00fcb74fc3454d80 f9 : 1003e0000000080000000 f10 : 1003e0000000000001431 f11 : 1003e0000000000989680 r1 : a000000100bfcf80 r2 : e0000000000000bd r3 : 000000000000308c r8 : 0000000000000000 r9 : e00000000fc31310 r10 : a000000100a13b28 r11 : 0000000000000000 r12 : e00000000fd0fdf0 r13 : e00000000fd08000 r14 : 0000000000000000 r15 : e00000000fcc8000 r16 : 0000000000000009 r17 : e000010000104000 r18 : e000010000104000 r19 : a000000100a13b40 r20 : a0000001009c23f0 r21 : a0000001009fd4d0 r22 : 0000000000004000 r23 : 0000000000000000 r24 : fffffffffff04c10 r25 : 0000000000000002 r26 : 0000000000000000 r27 : 0000000000000000 r28 : e00000000fd08bd4 r29 : a0000001007570b8 r30 : a0000001009e5500 r31 : a0000001009e54a0 Call Trace: [<a000000100026000>] show_stack+0x40/0xa0 sp=e00000000fd0f670 bsp=e00000000fd08f68 [<a000000100026a60>] show_regs+0x9a0/0x9e0 sp=e00000000fd0f840 bsp=e00000000fd08f10 [<a000000100037680>] die+0x260/0x3a0 sp=e00000000fd0f840 bsp=e00000000fd08ec8 [<a000000100037810>] die_if_kernel+0x50/0x80 sp=e00000000fd0f840 bsp=e00000000fd08e98 [<a00000010003eb40>] ia64_handle_unaligned+0x2ea0/0x2fc0 sp=e00000000fd0f840 bsp=e00000000fd08df0 [<a00000010001ca30>] ia64_prepare_handle_unaligned+0x30/0x60 sp=e00000000fd0fa10 bsp=e00000000fd08df0 [<a00000010005d100>] paravirt_leave_kernel+0x0/0x40 sp=e00000000fd0fc20 bsp=e00000000fd08df0 [<a0000001004c2ca0>] dev_kfree_skb_irq+0x20/0x1a0 sp=e00000000fd0fdf0 bsp=e00000000fd08db8 [<a0000001003efb70>] xennet_release_tx_bufs+0xd0/0x120 sp=e00000000fd0fdf0 bsp=e00000000fd08d78 [<a0000001003f14c0>] backend_changed+0xc40/0xf80 sp=e00000000fd0fdf0 bsp=e00000000fd08d08 [<a00000010034bd50>] otherend_changed+0x190/0x1c0 sp=e00000000fd0fe00 bsp=e00000000fd08cc8 [<a000000100349530>] xenwatch_thread+0x310/0x3c0 sp=e00000000fd0fe00 bsp=e00000000fd08ca0 [<a0000001000cb040>] kthread+0xe0/0x160 sp=e00000000fd0fe30 bsp=e00000000fd08c68 [<a000000100024450>] kernel_thread_helper+0x30/0x60 sp=e00000000fd0fe30 bsp=e00000000fd08c40 [<a00000010001a8a0>] start_kernel_thread+0x20/0x40 sp=e00000000fd0fe30 bsp=e00000000fd08c40 Kernel panic - not syncing: Aiee, killing interrupt handler!

2008-07-15mmc,sdio: helper function for transfer paddingPierre Ossman
There are a lot of crappy controllers out there that cannot handle all the request sizes that the MMC/SD/SDIO specifications require. In case the card driver can pad the data to overcome the problems, this commit adds a helper that calculates how much that padding should be. A corresponding helper is also added for SDIO, but it can also deal with all the complexities of splitting up a large transfer efficiently. Signed-off-by: Pierre Ossman <drzeus@drzeus.cx>
2008-07-15wireless: fix warnings from QoS patchJohannes Berg
When I removed the special "default" meaning from the QoS parameters, I forgot to update drivers and this lead to warnings because some drivers were checking for the special values and putting in defaults. This fixes that by removing the default special-casing completely. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-15netdev: Do not use TX lock to protect address lists.David S. Miller
Now that we have a specific lock to protect the network device unicast and multicast lists, remove extraneous grabs of the TX lock in cases where the code only needs address list protection. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-15netdev: Add netdev->addr_list_lock protection.David S. Miller
Add netif_addr_{lock,unlock}{,_bh}() helpers. Use them to protect operations that operate on or read the network device unicast and multicast address lists. Also use them in cases where the code simply wants to block calls into the driver's ->set_rx_mode() and ->set_multicast_list() methods. Signed-off-by: David S. Miller <davem@davemloft.net>
2008-07-14mlx4_core: Use MOD_STAT_CFG command to get minimal page sizeVladimir Sokolovsky
There was a bug in some versions of the mlx4 driver in mlx4_alloc_fmr(), which hardcoded the minimum acceptable page_shift to be 12. However, new ConnectX firmware can support a minimum page_shift of 9 (log_pg_sz of 9 returned by QUERY_DEV_LIM) -- so with old drivers, ib_fmr_alloc() would fail for ULPs using the device minimum when creating FMRs. To preserve firmware compatibility with released mlx4 drivers, the firmware will continue to return 12 as before for log_page_sz in QUERY_DEV_CAP for these drivers. However, to enable new drivers to take advantage of the available smaller page size, the mlx4 driver now first sets the log_pg_sz to the device minimum by setting a log_page_sz value to 0 via the MOD_STAT_CFG command and then reading the real minimum via QUERY_DEV_CAP.

2008-07-14RDMA/cxgb3: Fixes for zero STagSteve Wise
Handling the zero STag in receive work request requires some extra logic in the driver: - Only set the QP_PRIV bit for kernel mode QPs. - Add a zero STag build function for recv wrs. The uP needs a PBL allocated and passed down in the recv WR so it can construct a HW PBL for the zero STag S/G entries. Note: we need to place a few restrictions on zero STag usage because of this: 1) all SGEs in a recv WR must either be zero STag or not. No mixing. 2) an individual SGE length cannot exceed 128MB for a zero-stag SGE. This should be OK since it's not really practical to allocate such a large chunk of pinned contiguous DMA mapped memory. - Add an optimized non-zero-STag recv wr format for kernel users. This is needed to optimize both zero and non-zero STag cracking in the recv path for kernel users. - Remove the iwch_ prefix from the static build functions. - Bump required FW version.
