| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The i2400m->rx_roq data structure is protected against race conditions with a reference count (i2400m->rx_roq_refcount); the pointer can be read-referenced under the i2400m->rx_lock spinlock. The code in i2400m_rx_edata() wasn't properly following access protocol, performing an invalid check on i2400m->rx_roq (which is cleared to NULL when the refcount drops to zero). As such, it was missing to detect when the data structure is no longer valid and oopsing with a NULL pointer dereference. This commit fixes said check by verifying, under the rx_lock spinlock, that i2400m->rx_roq is non-NULL and then increasing the reference count before dropping the spinlock.

| | * | ath5k: consistently use rx_bufsize for RX DMABruno Randolf2010-05-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We should use the same buffer size we set up for DMA also in the hardware descriptor. Previously we used common->rx_bufsize for setting up the DMA mapping, but used skb_tailroom(skb) for the size we tell to the hardware in the descriptor itself. The problem is that skb_tailroom(skb) can give us a larger value than the size we set up for DMA before. This allows the hardware to write into memory locations not set up for DMA. In practice this should rarely happen because all packets should be smaller than the maximum 802.11 packet size. On the tested platform rx_bufsize is 2528, and we allocated an skb of 2559 bytes length (including padding for cache alignment) but sbk_tailroom() was 2592. Just consistently use rx_bufsize for all RX DMA memory sizes. Also use the return value of the descriptor setup function.

| | * | iwlwifi: fix internal scan raceReinette Chatre2010-05-21

What happens in this case is the cleanup done during the abort of the first internal scan also cleans up part of the new scan, causing it to access memory it shouldn't. Here are details: * First internal scan is triggered and scan command sent to device. * After seven seconds there is no scan results so the watchdog timer triggers a scan abort. * The scan abort succeeds and a SCAN_COMPLETE_NOTIFICATION is received for failed scan. * During processing of SCAN_COMPLETE_NOTIFICATION we clear STATUS_SCANNING and queue the "scan_completed" work. ** At this time, since the problem that caused the internal scan in first place is still present, a new internal scan is triggered. The behavior at this point is a bit different between 2.6.34 and 2.6.35 since 2.6.35 has a lot of this synchronized. The rest of the race description will thus be generalized. ** As part of preparing for the scan "is_internal_short_scan" is set to true. * At this point the completion work for fist scan is run. As part of this there is some locking missing around the "is_internal_short_scan" variable and it is set to "false". ** Now the second scan runs and it considers itself a real (not internal0 scan and thus causes problems with wrong memory being accessed. The fix is twofold. * Since "is_internal_short_scan" should be protected by mutex, fix this in scan completion work so that changes to it can be serialized. * Do not queue a new internal scan if one is in progress.

| * | ixgbe:add support for a new 82599 10G Base-T deviceMallikarjuna R Chilakala2010-05-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for a new copper device for 82599, device id 0x151c. This 82599 10GBase-T device uses the PHY's internal temperature sensor to guard against over-temp conditions. In this scenario the PHY will be put in a low power mode and link will no longer be able to transmit or receive any data. When this occurs, the over-temp interrupt is latched and driver logs this error message. A HW reset or power cycle is required to clear this status.

* | | driver core: add devname module aliases to allow module on-demand auto-loadingKay Sievers2010-05-25

Ideally all these modules would be compiled-in, but distros seems too much in love with their modularization that we need to cover the common cases with this new facility. It will allow us to remove a bunch of pretty useless init scripts and modprobes from init scripts. The static device node aliases will be carried in the module itself. The program depmod will extract this information to a file in the module directory: $ cat /lib/modules/2.6.34-00650-g537b60d-dirty/modules.devname # Device nodes to trigger on-demand module loading. microcode cpu/microcode c10:184 fuse fuse c10:229 ppp_generic ppp c108:0 tun net/tun c10:200 dm_mod mapper/control c10:235 Udev will pick up the depmod created file on startup and create all the static device nodes which the kernel modules specify, so that these modules get automatically loaded when the device node is accessed: $ /sbin/udevd --debug ... static_dev_create_from_modules: mknod '/dev/cpu/microcode' c10:184 static_dev_create_from_modules: mknod '/dev/fuse' c10:229 static_dev_create_from_modules: mknod '/dev/ppp' c108:0 static_dev_create_from_modules: mknod '/dev/net/tun' c10:200 static_dev_create_from_modules: mknod '/dev/mapper/control' c10:235 udev_rules_apply_static_dev_perms: chmod '/dev/net/tun' 0666 udev_rules_apply_static_dev_perms: chmod '/dev/fuse' 0666 A few device nodes are switched to statically allocated numbers, to allow the static nodes to work. This might also useful for systems which still run a plain static /dev, which is completely unsafe to use with any dynamic minor numbers. Note: The devname aliases must be limited to the *common* and *single*instance* device nodes, like the misc devices, and never be used for conceptually limited systems like the loop devices, which should rather get fixed properly and get a control node for losetup to talk to, instead of creating a random number of device nodes in advance, regardless if they are ever used. This facility is to hide the mess distros are creating with too modualized kernels, and just to hide that these modules are not compiled-in, and not to paper-over broken concepts.

In case of PIO-transfer it does not clear SDHC-status bit#11/12 in the INT-handler anymore. INT-handler might be called during an ongoing PIO-data-transfer (with some other INT-flag set) and PIO-transfer depends on these bits being set to detect the end of the data-transfer. This also means that at the end of PIO- transfer that PIO-software has to clear these bits itself. However in case of DMA-transfer these bits have to be cleared in the INT-handler, because they are used to generate INTs then. Works solid, no more problems here, can transfer big files.
