Author: marek Date: 2009-09-27 02:21:54 +0000 (Sun, 27 Sep 2009) New Revision: 1439 Modified: trunk/batman-adv-kernelland/hard-interface.c trunk/batman-adv-kernelland/routing.c Log: [batman-adv] fixing race condition while handling lots of data The callback batman_data_ready() set the variable data_ready_cond to true before waking up the packet handling thread. When the thread has completed its work it will sleep and sets the variable back to false. When the system has to handle large quantities of traffic the callback might be called several times while the packet handling thread runs. The status variable will be overwritten once the thread is done which might leave packets in the socket buffer. If the socket buffer is full no more packets are accepted and the callback won't be triggered. Therefore the packet receive thread has to reset the variable at the very beginning.

Author: marek Date: 2009-09-12 17:28:23 +0000 (Sat, 12 Sep 2009) New Revision: 1436 Modified: trunk/batman-adv-kernelland/device.c trunk/batman-adv-kernelland/main.c Log: [batman-adv] Remove compatibility code for pre 2.6 kernel versions The earliest version of linux which is compatible to batman-adv-kernelland is 2.6.20. Their are patches available in debian for batman-adv-kernelland 0.1 to make it build against linux 2.6.15, but they cannot be ported to current trunk due to changes to the working queues. To have "support" for much older versions isn't needed and can be removed without loosing any functionality. As result the only remaining LINUX_VERSION_CODE dependend precomiler code beside compat.h is for netdevice_ops support in soft-interface.c and result code checking of unregister_chrdev in device.c. For a possible merge into linux compat.h and all appearances of LINUX_VERSION_CODE should be removed according to checkpatch.pl.
