medusa_set_videostandard() takes the lock but it always drops it before returning. This was found with a static checker and compile tested only. :/ Signed-off-by:

The check for dio_num_asics is used to determine if there is more than 1 irq. If it is false then irq[1] is past the end of the array. Signed-off-by:

sizeof() returns a size_t but the other types involved are unsigned long, so using min() results in a warning. As sizeof() is called on an 11 character buffer defined immediately above unsigned long is obviously wide enough for the result. Signed-off-by:

$ make CONFIG_DEBUG_SECTION_MISMATCH=y WARNING: drivers/staging/rt2870/rt2870sta.o(.text+0x2f4c5): Section mismatch in reference from the function rtusb_probe() to the function .devinit.text:rt2870_probe() The function rtusb_probe() references the function __devinit rt2870_probe(). This is often because rtusb_probe lacks a __devinit annotation or the annotation of rt2870_probe is wrong. Signed-off-by:

The HV core mucks around with specific irqs and other low-level stuff and takes forever to determine that it really shouldn't be running on a machine. So instead, trigger off of the DMI system information and error out much sooner. This also allows the module loading tools to recognize that this code should be loaded on this type of system.

This allows the HV core to be properly found and autoloaded by the system tools. It uses the Microsoft virtual VGA device to trigger this. Cc: Haiyang Zhang <haiyangz@microsoft.com> Cc: Hank Janssen <hjanssen@microsoft.com> Cc: stable <stable@kernel.org> Signed-off-by: -

This is a patch to the RingBuffer.c file that corrects various coding style warnings and errors found by checkpatch.pl [ The real solution here is to get rid of this file entirely, and use the kernel's internal ring buffer api, but until then, make these changes so as to make checkpatch.pl happy, and keep others from continuously sending this type of patch. - gkh] Signed-off-by:

printk() since kernel version 2.6.29 has supported printing MAC addresses directly, as an extension to the %p processing. This patch makes use of this for printk() and bat_dbg(). This will remove the overhead of using addr_to_string() which is normally never actually output. Fixed a typo found by Gus Wirth. Signed-off-by:

Some embedded devices have very limited sources of entropy for the random number generator. It has been observed that the random MAC address on the interface bat0 is not always random. When testing with a collection of identical hardware, sometimes the bat0 device the same MAC address on multiple devices, causing mayhem. This patch allows the MAC address to be set by the user.

This patch removes the (ugly and racy) packet receiving thread and the kernel socket usage. Instead, packets are received directly by registering the ethernet type and handling skbs instead of self-allocated buffers. Some consequences and comments: * we don't copy the payload data when forwarding/sending/receiving data anymore. This should boost performance. * packets from/to different interfaces can be (theoretically) processed simultaneously. Only the big originator hash lock might be in the way. * no more polling or sleeping/wakeup/scheduling issues when receiving packets * this might introduce new race conditions. * aggregation and vis code still use packet buffers and are not (yet) converted. * all spinlocks were converted to irqsave/restore versions to solve some lifelock issues when preempted. This might be overkill, some of these locks might be reverted later. * skb copies are only done if neccesary to avoid overhead performance differences: * we made some "benchmarks" with intel laptops. * bandwidth on Gigabit Ethernet increased from ~500 MBit/s to ~920 MBit/s * ping latency decresed from ~2ms to ~0.2 ms I did some tests on my 9 node qemu environment and could confirm that usual sending/receiving, forwarding, vis, batctl ping etc works.

there are some kmallocs left which are not checked whether they succeeds or not, which might lead to corrupted data structures if the system memory is full. This patch should clean up the remaining unchecked kmalloc()s. Signed-off-by:

The /proc vis file was used to enable/disable the vis server and to output the vis data at the same time. This behaviour was confusing and lacked a proper method to display the current vis server status. This patch seperates the 2 functionalities: * use vis_server to enable/disable the vis server and to retrieve its status * use vis_data to retrieve the vis raw data (if the server is enabled) Signed-off-by:

batman-adv used to export the vis data using different formats that were switchable via /proc/net/batman-adv/vis_format. The various formats moved to user space and rendered this configuration switch useless. Signed-off-by:

Andrew Lunn authored
The batman-adv kernel module is able to output visualization data using the dot draw or JSON format. This patch transforms the output into a generic format (called vis raw). User space tool may convert the raw data to support a variety of formats without the need of modifying the kernel module. Signed-off-by:

This patches fixes two rounding issues in vis.c for sending and purging vis packets. Before, the timers and timeouts always got rounded down to seconds, though we want a precision in milliseconds. This also fixes a kernel panic that occures when lowering the timer for sending vis packets (vis_interval) to less than 1000ms in main.c manually. Signed-off-by:

forw_bcast_list_lock is spin_locked in both process and softirq context. SoftIRQ calls the spinlock with disabled IRQ and normal process context with enabled IRQs. When process context is inside an spin_locked area protected by forw_bcast_list_lock and gets interrupted by an IRQ, it could happen that something tries to lock forw_bcast_list_lock again in SoftIRQ context. It cannot proceed further since the lock is already taken somewhere else, but no reschedule will happen inside the SoftIRQ context. This leads to an complete kernel hang without any chance of resurrection. All functions called in process context must disable IRQs when they try to get get that lock to to prevent any reschedule due to IRQs. Signed-off-by:

instead of dynamically registering hash iterators, calling functions are changed to register the iterator objects statically. The two advantages are: * no memory leaks when aborting from hash_iterate() * no calls to kmalloc/kfree, therefore a little faster/safer Tested with 9 QEMU instances, no obvious regression found.
