2009-05-06Ignore madvise(MADV_WILLNEED) for hugetlbfs-backed regionsMel Gorman1-0/+8
madvise(MADV_WILLNEED) forces page cache readahead on a range of memory backed by a file. The assumption is made that the page required is order-0 and "normal" page cache. On hugetlbfs, this assumption is not true and order-0 pages are allocated and inserted into the hugetlbfs page cache. This leaks hugetlbfs page reservations and can cause BUGs to trigger related to corrupted page tables. This patch causes MADV_WILLNEED to be ignored for hugetlbfs-backed regions.

2009-05-05i2c-algo-pca: Let PCA9564 recover from unacked data byte (state 0x30)Enrik Berkhan1-0/+11
Currently, the i2c-algo-pca driver does nothing if the chip enters state 0x30 (Data byte in I2CDAT has been transmitted; NOT ACK has been received). Thus, the i2c bus connected to the controller gets stuck afterwards. I have seen this kind of error on a custom board in certain load situations most probably caused by interference or noise. A possible reaction is to let the controller generate a STOP condition. This is documented in the PCA9564 data sheet (2006-09-01) and the same is done for other NACK states as well. Further, state 0x38 isn't handled completely, either. Try to do another START in this case like the data sheet says. As this couldn't be tested, I've added a comment to try to reset the chip if the START doesn't help as suggested by Wolfram Sang.

The VESA spec states 2ms is the DDC timeout, so when this translates into 1 jiffie and we are close to the end of the time period, it could return with a timeout less than 2ms.

2009-05-05e1000: fix virtualization bugJesse Brandeburg1-1/+1
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.

2009-05-05proc: avoid information leaks to non-privileged processesJake Edge2-5/+13
By using the same test as is used for /proc/pid/maps and /proc/pid/smaps, only allow processes that can ptrace() a given process to see information that might be used to bypass address space layout randomization (ASLR). These include eip, esp, wchan, and start_stack in /proc/pid/stat as well as the non-symbolic output from /proc/pid/wchan. ASLR can be bypassed by sampling eip as shown by the proof-of-concept code at http://code.google.com/p/fuzzyaslr/ As part of a presentation (http://www.cr0.org/paper/to-jt-linux-alsr-leak.pdf) esp and wchan were also noted as possibly usable information leaks as well. The start_stack address also leaks potentially useful information.

2009-05-05Bluetooth: Fix issue with sysfs handling for connectionsMarcel Holtmann3-34/+43
Due to a semantic changes in flush_workqueue() the current approach of synchronizing the sysfs handling for connections doesn't work anymore. The whole approach is actually fully broken and based on assumptions that are no longer valid. With the introduction of Simple Pairing support, the creation of low-level ACL links got changed. This change invalidates the reason why in the past two independent work queues have been used for adding/removing sysfs devices. The adding of the actual sysfs device is now postponed until the host controller successfully assigns an unique handle to that link. So the real synchronization happens inside the controller and not the host. The only left-over problem is that some internals of the sysfs device handling are not initialized ahead of time. This leaves potential access to invalid data and can cause various NULL pointer dereferences. To fix this a new function makes sure that all sysfs details are initialized when an connection attempt is made. The actual sysfs device is only registered when the connection has been successfully established. To avoid a race condition with the registration, the check if a device is registered has been moved into the removal work. As an extra protection two flush_work() calls are left in place to make sure a previous add/del work has been completed first.

2009-05-04usbnet: CDC EEM support (v5)Omar Laazimani4-0/+399
This introduces a CDC Ethernet Emulation Model (EEM) host side driver to support USB EEM devices. 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.

2009-05-03Move dtc and libfdt sources from arch/powerpc/boot to scripts/dtcDavid Gibson33-45/+83
The powerpc kernel always requires an Open Firmware like device tree to supply device information. On systems without OF, this comes from a flattened device tree blob. This blob is usually generated by dtc, a tool which compiles a text description of the device tree into the flattened format used by the kernel. Sometimes, the bootwrapper makes small changes to the pre-compiled device tree blob (e.g. filling in the size of RAM). To do this it uses the libfdt library. Because these are only used on powerpc, the code for both these tools is included under arch/powerpc/boot (these were imported and are periodically updated from the upstream dtc tree). However, the microblaze architecture, currently being prepared for merging to mainline also uses dtc to produce device tree blobs. A few other archs have also mentioned some interest in using dtc. Therefore, this patch moves dtc and libfdt from arch/powerpc into scripts, where it can be used by any architecture. The vast bulk of this patch is a literal move, the rest is adjusting the various Makefiles to use dtc and libfdt correctly from their new locations.
