[alfred] master: alfred: Move tx finish functionality in extra function (08a2de7)
by postmaster＠open-mesh.org 17 Nov '16

Repository : ssh://git@open-mesh.org/alfred On branch : master >--------------------------------------------------------------- commit 08a2de792eee543df06ac3253d59941391a3f2af Author: Sven Eckelmann <sven(a)narfation.org> Date: Sat Nov 12 10:25:19 2016 +0100 alfred: Move tx finish functionality in extra function The process_alfred_status_txend has two main functionalities. It first tries to find a transaction to be able to get its status. When it was found then it either commits the data or just cleans it up. The latter will be used by later by process_alfred_push_data to implement out-of-order txend packets. Thus split process_alfred_status_txend now into two functions to avoid code duplication.

With some carefully placed msleep()s/mdelay()s it can be reproduced easily. The issue is, that on interface removal, any still running worker thread of a forwarding packet will race with the interface purging routine to free a forwarding packet. Temporarily giving up a spin-lock to be able to sleep in the purging routine is not safe. Furthermore, there is a potential general protection fault not just for the purging side shown above, but also on the worker side: Temporarily removing a forw_packet from the according forw_{bcast,bat}_list will make it impossible for the purging routine to catch and cancel it. # How this patch tries to fix it: With this patch we split the queue purging into three steps: Step 1), removing forward packets from the queue of an interface and by that claim it as our responsibility to free. Step 2), we are either lucky to cancel a pending worker before it starts to run. Or if it is already running, we wait and let it do its thing, except two things: Through the claiming in step 1) we prevent workers from a) re-arming themselves. And b) prevent workers from freeing packets which we still hold in the interface purging routine. Finally, step 3, we are sure that no forwarding packets are pending or even running anymore on the interface to remove. We can then safely free the claimed forwarding packets.

If the interface batman-adv has been configured with is a virtual interface (e.g. VLAN) it would not be properly detected as WiFi interface and thus not benefit from the special WiFi treatment. This patch changes that by peeking under the hood whenever a virtual interface is in play.

Some of them can take the rtnl semaphore and some of them already have the semaphore taken. But even others don't allow that the semaphore will be taken. The data has to be retrieved when the hardif is added to batman-adv because some of the wifi information for an hardif will only be available with rtnl lock. It can then be cached in the batadv_hard_iface and the functions is_wifi_netdev and is_cfg80211_netdev can just compare the correct bits without imposing extra locking requirements.
