Hi David, Antonio currently seems to be occupied. This is currently rather unfortunate because there are patches waiting in the batman-adv development repository maint(enance) branch [1] since up to 6 weeks. I am now getting asked when these patches will hit the distribution kernels and therefore decided to submit these patches directly to netdev.
The patch from Simon works around the problem that warnings could be triggered
in the translation table code via packets using a VLAN not configured on the
target host. This warning was replaced with a rate limited info message.
Ben Hutchings found an superfluous batadv_softif_vlan_put in the error
handling code of the translation table while he backported the "batman-adv:
Fix reference counting of vlan object for tt_local_entry" patch to the stable
kernels. He noticed correctly that this batadv_softif_vlan_put should also
have been removed by the said patch.
The most requested fix at the moment is related to a double free in the
translation table code. It is a race condition which mostly happens on systems
with multiple cores and multiple network interface attached to batman-adv. Two
Freifunk communities which were haunted by weird crashes (with backtraces
reporting problems in other parts of the kernel) were kind enough to test this
patch. They reported that there systems are now running stable after applying
this patch.
An invalid memory access was detected in the batadv_icmp_packet_rr handling
code when receiving a skbuff with fragments. The last patch is fixing a memory
leak when the interface is removed via .dellink. The code to fix it was copied
from the code handling the legacy sysfs interface to remove netdevices from a
batman-adv netdevice.
There are still 28 patches in the development tree for v4.8 but I will leave
them to Antonio because these are cleanups and features and therefore for net-
next.
