[B.A.T.M.A.N.] [PATCH] batman-adv: fix delayed foreign originator recognition
by Linus Lüssing 09 Nov '14

09 Nov '14

Currently it can happen that the reception of an OGM from a new originator is not being accepted. More precisely it can happen that an originator struct gets allocated and initialized (batadv_orig_node_new()), even the TQ gets calculated and set correctly (batadv_iv_ogm_calc_tq()) but still the periodic orig_node purging thread will decide to delete it if it has a chance to jump between these two function calls. This is because batadv_orig_node_new() initializes the last_seen value to zero and its caller (batadv_iv_ogm_orig_get()) makes it visible to other threads by adding it to the hash table already. batadv_iv_ogm_calc_tq() will set the last_seen variable to the correct, current time a few lines later but if the purging thread jumps in between that it will think that the orig_node timed out and will wrongly schedule it for deletion already. If the purging interval is the same as the originator interval (which is the default: 1 second), then this game can continue for several rounds until the random OGM jitter added enough difference between these two (in tests, two to about four rounds seemed common). Fixing this by initializing the last_seen variable of an orig_node to the current time before adding it to the hash table.

[B.A.T.M.A.N.] [PATCH] batman-adv: Fix double fetch in RCU version of hlist_*entry*
by Sven Eckelmann 09 Nov '14

09 Nov '14

The backported (<3.9) version of hlist_for_each_entry_rcu and hlist_for_each_entry_safe uses the new macro hlist_entry_safe. It is called with an ACCESS_ONCE parameter for the first parameter ptr. This disallows merging of the two loads which the current version of the macro uses. This is problematic because this macro must only generate one load. Otherwise with two contexts (or CPUs) following could happen: 1. context 1 fetches the ptr to the last entry in hlist_entry_safe() and accepts this non-NULL ptr 2. context 2 deletes the last entry and terminates the list with NULL 3. context 1 re-fetches the pointer, doesn't check for zero, calculates the entry based on a NULL pointer 4. context 1 crashes because it tries to load/write data from/to the invalid address Instead use a single load to a temporary variable and do the NULL-check and calculation based on that one.

[B.A.T.M.A.N.] [PATCH] list: fix order of arguments for hlist_add_after(_rcu)
by Sven Eckelmann 09 Nov '14

09 Nov '14

From: Ken Helias <kenhelias(a)firemail.de> All other add functions for lists have the new item as first argument and the position where it is added as second argument. This was changed for no good reason in this function and makes using it unnecessary confusing. The name was changed to hlist_add_behind() to cause unconverted code to generate a compile error instead of using the wrong parameter order.

by Simon Wunderlich 09 Nov '14

The current condition actually does NOT consider bonding when the interface the packet came in from is the soft interface, which is the opposite of what it should do (and the comment describes).

[B.A.T.M.A.N.] Master thesis with B.A.T.M.A.N.
by Tobias Hardes 07 Nov '14

07 Nov '14

Hi all, short self introduction: My name is Tobias and I am a member of Freifunk in Paderborn. Currently I am studying computer science at the university of Paderborn and I am going to finish my studies at the end of next summer term. For this I have to work on a thesis and I after I had a few discussions with one of the professors and the other participants from our Freifunk group, I worked on a thesis description which is about a simulation of the Freifunk-Network in Paderborn with a focus on B.A.T.M.A.N.. The description is available here: http://www.ccs-labs.org/theses/MA-201410-Freifunk.pdf We have more than 500 nodes in Paderborn which are using B.A.T.M.A.N. and we have a few problems here (see the document). The overall goal is to create a simulation using OMNet++ and do an evaluation of the results. This E-Mail is just to inform You about this plan. The actual work will start in March/April. BR Tobias
