2009-04-17macb: process the RX ring regardless of interrupt statusErik Waling
Suppose that we receive lots of frames, start processing them, but exhaust our budget so that we return before we had a chance to look at all of them. Then, when the network layer calls us again, we will only continue processing the buffers if the REC bit was set in the mean time, which it might not be if there was a brief pause in the flow of packets. If this happens, we'll simply display a warning and call netif_rx_complete() with potentially lots of unprocessed packets in the RX ring... Fix this by scanning the ring no matter what flags are set in the interrupt status register.

2009-04-17md: update sync_completed and reshape_position even more often.NeilBrown
There are circumstances when a user-space process might need to "oversee" a resync/reshape process. For example when doing an in-place reshape of a raid5, it is prudent to take a backup of each section before reshaping it as this is the only way to provide safety against an unplanned shutdown (i.e. crash/power failure). The sync_max sysfs value can be used to stop the resync from advancing beyond a particular point. So user-space can: suspend IO to the first section and back it up set 'sync_max' to the end of the section wait for 'sync_completed' to reach that point resume IO on the first section and move on to the next section. However this process requires the kernel and user-space to run in lock-step which could introduce unnecessary delays. It would be better if a 'double buffered' approach could be used with userspace and kernel space working on different sections with the 'next' section always ready when the 'current' section is finished. One problem with implementing this is that sync_completed is only guaranteed to be updated when the sync process reaches sync_max. (it is updated on a time basis at other times, but it is hard to rely on that). This defeats some of the double buffering. With this patch, sync_completed (and reshape_position) get updated as the current position approaches sync_max, so there is room for userspace to advance sync_max early without losing updates. To be precise, sync_completed is updated when the current sync position reaches half way between the current value of sync_completed and the value of sync_max. This will usually be a good time for user space to update sync_max. If sync_max does not get updated, the updates to sync_completed (together with associated metadata updates) will occur at an exponentially increasing frequency which will get unreasonably fast (one update every page) immediately before the process hits sync_max and stops. So the update rate will be unreasonably fast only for an insignificant period of time. Signed-off-by: NeilBrown <neilb@suse.de>

2009-04-16Driver Core: early platform driverMagnus Damm
V3 of the early platform driver implementation. Platform drivers are great for embedded platforms because we can separate driver configuration from the actual driver. So base addresses, interrupts and other configuration can be kept with the processor or board code, and the platform driver can be reused by many different platforms. For early devices we have nothing today. For instance, to configure early timers and early serial ports we cannot use platform devices. This because the setup order during boot. Timers are needed before the platform driver core code is available. The same goes for early printk support. Early in this case means before initcalls. These early drivers today have their configuration either hard coded or they receive it using some special configuration method. This is working quite well, but if we want to support both regular kernel modules and early devices then we need to have two ways of configuring the same driver. A single way would be better. The early platform driver patch is basically a set of functions that allow drivers to register themselves and architecture code to locate them and probe. Registration happens through early_param(). The time for the probe is decided by the architecture code. See Documentation/driver-model/platform.txt for more details.

2009-04-16rt2x00: prevent double kfree when failing to register hardwareHerton Ronaldo Krzesinski
In a scenario where there isn't any firmware available, we will have a double kfree of rt2x00dev->spec.channels_info when ieee80211_register_hw returns an error status inside rt2x00lib_probe_hw. The problem is that if ieee80211_register_hw fails, we call rt2x00lib_remove_hw twice: * first inside rt2x00lib_probe_hw upon failure of ieee80211_register_hw * error status is returned to rt2x00lib_probe_dev, which then sees it and calls in this case rt2x00lib_remove_dev that will again run rt2x00lib_remove_hw Prevent this avoiding calling rt2x00lib_remove_hw inside rt2x00lib_probe_hw Problem was detected with CONFIG_DEBUG_PAGEALLOC=y, CONFIG_SLUB_DEBUG=y, CONFIG_SLUB_DEBUG_ON=y, that dumps this with no firmware available: rt61pci 0000:00:07.0: PCI INT A -> GSI 19 (level, low) -> IRQ 19 wmaster0 (rt61pci): not using net_device_ops yet phy0: Selected rate control algorithm 'pid' phy0: Failed to initialize wep: -2 phy0 -> rt2x00lib_probe_dev: Error - Failed to initialize hw. ============================================================================= BUG kmalloc-128: Object already free ----------------------------------------------------------------------------- INFO: Allocated in rt61pci_probe_hw+0x3e5/0x6e0 [rt61pci] age=340 cpu=0 pid=21 INFO: Freed in rt2x00lib_remove_hw+0x59/0x70 [rt2x00lib] age=0 cpu=0 pid=21 INFO: Slab 0xc13ac3e0 objects=23 used=10 fp=0xdd59f6e0 flags=0x400000c3 INFO: Object 0xdd59f6e0 @offset=1760 fp=0xdd59f790 Bytes b4 0xdd59f6d0: 15 00 00 00 b2 8a fb ff 5a 5a 5a 5a 5a 5a 5a 5a ....².ûÿZZZZZZZZ Object 0xdd59f6e0: 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b kkkkkkkkkkkkkkkk Object 0xdd59f6f0: 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b kkkkkkkkkkkkkkkk Object 0xdd59f700: 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b kkkkkkkkkkkkkkkk Object 0xdd59f710: 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b kkkkkkkkkkkkkkkk Object 0xdd59f720: 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b kkkkkkkkkkkkkkkk Object 0xdd59f730: 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b kkkkkkkkkkkkkkkk Object 0xdd59f740: 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b kkkkkkkkkkkkkkkk Object 0xdd59f750: 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b 6b a5 kkkkkkkkkkkkkkk¥ Redzone 0xdd59f760: bb bb bb bb »»»» Padding 0xdd59f788: 5a 5a 5a 5a 5a 5a 5a 5a ZZZZZZZZ Pid: 21, comm: stage1 Not tainted 2.6.29.1-desktop-1.1mnb #1 Call Trace: [<c01abbb3>] print_trailer+0xd3/0x120 [<c01abd37>] object_err+0x37/0x50 [<c01acf57>] __slab_free+0xe7/0x2f0 [<c01ad1de>] kfree+0x7e/0xd0 [<e0e4a239>] ? rt2x00lib_remove_hw+0x59/0x70 [rt2x00lib] [<e0e4a239>] ? rt2x00lib_remove_hw+0x59/0x70 [rt2x00lib] [<e0e4a239>] rt2x00lib_remove_hw+0x59/0x70 [rt2x00lib] [<e0e4acc7>] rt2x00lib_remove_dev+0x37/0x50 [rt2x00lib] [<e0e4b087>] rt2x00lib_probe_dev+0x1a7/0x3b0 [rt2x00lib] [<e0eb288f>] rt2x00pci_probe+0xdf/0x1ee [rt2x00pci] [<c026b9ee>] local_pci_probe+0xe/0x10 [<c026c750>] pci_device_probe+0x60/0x80 [<c02d5c2a>] driver_probe_device+0x9a/0x2e0 [<c02d5ef9>] __driver_attach+0x89/0x90 [<c02d541b>] bus_for_each_dev+0x4b/0x70 [<c026c690>] ? pci_device_remove+0x0/0x40 [<c02d59d9>] driver_attach+0x19/0x20 [<c02d5e70>] ? __driver_attach+0x0/0x90 [<c02d4cef>] bus_add_driver+0x1cf/0x2a0 [<c026c690>] ? pci_device_remove+0x0/0x40 [<c02d60c9>] driver_register+0x69/0x140 [<c026c9b0>] __pci_register_driver+0x40/0x80 [<e0ecc000>] ? rt61pci_init+0x0/0x19 [rt61pci] [<e0ecc017>] rt61pci_init+0x17/0x19 [rt61pci] [<c0101116>] do_one_initcall+0x26/0x1c0 [<c01ab90c>] ? slab_pad_check+0x3c/0x120 [<c01ab90c>] ? slab_pad_check+0x3c/0x120 [<c01ac8da>] ? check_object+0xda/0x210 [<c01b0026>] ? percpu_free+0x46/0x50 [<c01ad09e>] ? __slab_free+0x22e/0x2f0 [<c01b0026>] ? percpu_free+0x46/0x50 [<c01b0026>] ? percpu_free+0x46/0x50 [<c01b0026>] ? percpu_free+0x46/0x50 [<c01687ec>] ? stop_machine_destroy+0x3c/0x40 [<c015e515>] ? load_module+0xa5/0x1c50 [<e0ec5000>] ? rt61pci_eepromregister_read+0x0/0x40 [rt61pci] [<e0eb2000>] ? rt2x00pci_write_tx_data+0x0/0x90 [rt2x00pci] [<c03ac2fb>] ? mutex_lock+0xb/0x20 [<c03ac2fb>] ? mutex_lock+0xb/0x20 [<c017ad16>] ? tracepoint_update_probe_range+0x76/0xa0 [<c017ad6f>] ? tracepoint_module_notify+0x2f/0x40 [<c03b02ed>] ? notifier_call_chain+0x2d/0x70 [<c014f0ed>] ? __blocking_notifier_call_chain+0x4d/0x60 [<c014f11a>] ? blocking_notifier_call_chain+0x1a/0x20 [<c0160156>] sys_init_module+0x96/0x1d0 [<c019dad6>] ? sys_munmap+0x46/0x60 [<c0105546>] syscall_call+0x7/0xb FIX kmalloc-128: Object at 0xdd59f6e0 not freed rt61pci 0000:00:07.0: PCI INT A disabled rt61pci: probe of 0000:00:07.0 failed with error -2 Signed-off-by: Herton Ronaldo Krzesinski <herton@mandriva.com.br> Acked-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2009-04-16b43: Refresh RX poison on buffer recyclingMichael Buesch
The RX buffer poison needs to be refreshed, if we recycle an RX buffer, because it might be (partially) overwritten by some DMA operations.

2009-04-16b43: Poison RX buffersMichael Buesch
This patch adds poisoning and sanity checking to the RX DMA buffers. This is used for protection against buggy hardware/firmware that raises RX interrupts without doing an actual DMA transfer. This mechanism protects against rare "bad packets" (due to uninitialized skb data) and rare kernel crashes due to uninitialized RX headers. The poison is selected to not match on valid frames and to be cheap for checking. The poison check mechanism _might_ trigger incorrectly, if we are voluntarily receiving frames with bad PLCP headers. However, this is nonfatal, because the chance of such a match is basically zero and in case it happens it just results in dropping the packet. Bad-PLCP RX defaults to off, and you should leave it off unless you want to listen to the latest news broadcasted by your microwave oven. This patch also moves the initialization of the RX-header "length" field in front of the mapping of the DMA buffer. The CPU should not touch the buffer after we mapped it.

Prevent ixgbe from putting the adapter into D3 during shutdown except when we're going to power off the system, since doing that may generally cause problems with kexec to happen (such problems were observed for igb and forcedeth). For this purpose seperate ixgbe_shutdown() from ixgbe_suspend() and use the appropriate PCI PM callbacks in both of them. Signed-off-by: "Rafael J.

2009-04-15Input: ads7846 - fix unsafe disable_irqBen Nizette
The use of disable_irq inside the handler for the interrupt being disabled has always been dangerous. disable_irq should wait for that handler to complete before returning -> deadlock. For some reason this wasn't actually the case until 3aa551c9b was merged but since this time, the ads7846 driver has deadlocked the system on first interrupt. Convert the driver to use the handler-safe _nosync variant. Signed-off-by: Ben Nizette <bn@niasdigital.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
