[B.A.T.M.A.N.] Missing patches in net-next
by Sven Eckelmann 21 Dec '15

21 Dec '15

Hi, it seems a bunch of patches are missing in net-next from batman-adv next's branch. An incorrect lockdep_assert was fixed to refer to the correct lock. The flag FIRST_HOP was dropped because it is not used anymore in the batman-adv compat version 15. The bridge loop avoidance code will now cleanup its internal state when it gets disabled. This is required to reset itself in case it gets restarted again. Also the behavior when the user tries to enable the already started bridge loop avoidance was modified to just ignore this trigger. It was also tuned to better cope with networks using very lossy links. The rest are only contain minor cleanups of the code, updates of the documentation and kerneldoc inside the batman-adv source code. Kind regards, Sven Antonio Quartulli (3): batman-adv: fix kerneldoc for DAT functions batman-adv: fix kerneldoc for TT functions batman-adv: add kernel doc for AP isolation attributes in bat_priv Marek Lindner (2): batman-adv: remove leftovers of unused BATADV_PRIMARIES_FIRST_HOP flag batman-adv: kernel doc readability updates Markus Elfring (4): batman-adv: Delete unnecessary checks before the function call "kfree_skb" batman-adv: Less checks in batadv_tvlv_unicast_send() batman-adv: Delete an unnecessary check before the function call "batadv_softif_vlan_free_ref" batman-adv: Split a condition check Simon Wunderlich (5): batman-adv: Start new development cycle batman-adv: purge bridge loop avoidance when its disabled batman-adv: increase BLA wait periods to 6 batman-adv: only call post function if something changed batman-adv: Update/repair bridge loop avoidance kerneldoc Sven Eckelmann (14): batman-adv: Fix lockdep annotation of batadv_tlv_container_remove batman-adv: Add function to convert string to batadv throughput batman-adv: Change ifconfig examples to iproute2 batman-adv: Fix kernel-doc parsing of main structs batman-adv: Fix kerneldoc member names in for main structs batman-adv: Remove kerneldoc for missing struct members batman-adv: Add kerneldoc for batadv_neigh_node::refcount batman-adv: Fix kerneldoc parsing of structs/enums batman-adv: Remove kerneldoc for missing parameters batman-adv: Fix names in kerneldoc of functions batman-adv: Drop invalid kerneldoc for variable batadv_vlan_attrs batman-adv: Fix kerneldoc parsing of return description batman-adv: Fix kerneldoc of main functions batman-adv: Fix kerneldoc of network-coding functions Documentation/networking/batman-adv.txt | 9 +- net/batman-adv/bat_iv_ogm.c | 21 ++- net/batman-adv/bitarray.c | 12 +- net/batman-adv/bitarray.h | 12 +- net/batman-adv/bridge_loop_avoidance.c | 247 ++++++++++++++++++++++++-------- net/batman-adv/bridge_loop_avoidance.h | 2 + net/batman-adv/debugfs.c | 6 + net/batman-adv/distributed-arp-table.c | 41 +++--- net/batman-adv/fragmentation.c | 18 +-- net/batman-adv/fragmentation.h | 2 +- net/batman-adv/gateway_client.c | 14 +- net/batman-adv/gateway_common.c | 119 +++++++-------- net/batman-adv/hard-interface.c | 7 +- net/batman-adv/hash.h | 22 +-- net/batman-adv/main.c | 45 +++--- net/batman-adv/main.h | 21 ++- net/batman-adv/multicast.c | 35 +++-- net/batman-adv/multicast.h | 2 +- net/batman-adv/network-coding.c | 59 ++++---- net/batman-adv/originator.c | 54 ++++--- net/batman-adv/packet.h | 20 +-- net/batman-adv/routing.c | 36 +++-- net/batman-adv/send.c | 32 +++-- net/batman-adv/send.h | 4 +- net/batman-adv/soft-interface.c | 18 +-- net/batman-adv/sysfs.c | 31 ++-- net/batman-adv/translation-table.c | 125 +++++++++------- net/batman-adv/types.h | 60 ++++---- 28 files changed, 650 insertions(+), 424 deletions(-)

[B.A.T.M.A.N.] [PATCH 01/23] batman-adv: Fix list removal of batadv_hardif_neigh_node
by Sven Eckelmann 19 Dec '15

19 Dec '15

The neigh_list with batadv_hardif_neigh_node objects is accessed with only rcu_read_lock in batadv_neigh_node_get and batadv_iv_neigh_print. Thus is is not allowed to kfree the object before the rcu grace period ends which may still tries to access this object. Therefore the object has first to be removed from the neigh_list and then it has either wait with synchronize_rcu or call_rcu till the grace period ends before it can be freed. Signed-off-by: Sven Eckelmann <sven(a)narfation.org> --- I have no idea why batadv_hardif_neigh_free_now is considered to be safe to call. The only caller is batadv_neigh_node_free_rcu but this function never makes sure that the previously mentioned two functions are actually not accessing it right now when hlist_del_rcu_init + kfree is called. --- net/batman-adv/originator.c | 18 ++++++++++++------ 1 file changed, 12 insertions(+), 6 deletions(-) diff --git a/net/batman-adv/originator.c b/net/batman-adv/originator.c index 00b0437..2681c7d 100644 --- a/net/batman-adv/originator.c +++ b/net/batman-adv/originator.c @@ -217,10 +217,6 @@ static void batadv_hardif_neigh_free_rcu(struct rcu_head *rcu) hardif_neigh = container_of(rcu, struct batadv_hardif_neigh_node, rcu); - spin_lock_bh(&hardif_neigh->if_incoming->neigh_list_lock); - hlist_del_init_rcu(&hardif_neigh->list); - spin_unlock_bh(&hardif_neigh->if_incoming->neigh_list_lock); - batadv_hardif_free_ref_now(hardif_neigh->if_incoming); kfree(hardif_neigh); } @@ -233,8 +229,13 @@ static void batadv_hardif_neigh_free_rcu(struct rcu_head *rcu) static void batadv_hardif_neigh_free_now(struct batadv_hardif_neigh_node *hardif_neigh) { - if (atomic_dec_and_test(&hardif_neigh->refcount)) + if (atomic_dec_and_test(&hardif_neigh->refcount)) { + spin_lock_bh(&hardif_neigh->if_incoming->neigh_list_lock); + hlist_del_init_rcu(&hardif_neigh->list); + spin_unlock_bh(&hardif_neigh->if_incoming->neigh_list_lock); + batadv_hardif_neigh_free_rcu(&hardif_neigh->rcu); + } } /** @@ -244,8 +245,13 @@ batadv_hardif_neigh_free_now(struct batadv_hardif_neigh_node *hardif_neigh) */ void batadv_hardif_neigh_free_ref(struct batadv_hardif_neigh_node *hardif_neigh) { - if (atomic_dec_and_test(&hardif_neigh->refcount)) + if (atomic_dec_and_test(&hardif_neigh->refcount)) { + spin_lock_bh(&hardif_neigh->if_incoming->neigh_list_lock); + hlist_del_init_rcu(&hardif_neigh->list); + spin_unlock_bh(&hardif_neigh->if_incoming->neigh_list_lock); + call_rcu(&hardif_neigh->rcu, batadv_hardif_neigh_free_rcu); + } } /** -- 2.6.4

[B.A.T.M.A.N.] Super high package loss and weak connection
by no name 18 Dec '15

18 Dec '15

Hello there Hallo (deutsche Version unten) I have a simple batman setup that does behave odd: Raspberry b+, jessie, batman-adv2015.2 witha single LOGILINK WL0084B USB wifi stick attached I have 5 rasperries that can see each other via wifi (one of them is a gw(BASE2), one of them (SHELF_1) is not directly reachable by the gw, because they are in a line from one room to another and has to be reached via one single hop in between) digraph { { "BASE_2" } "BASE_2" -> "SHELF_3 @ ra" [label="1.689"] "BASE_2" -> "SHELF_5 @ Bar" [label="1.689"] "BASE_2" -> "SHELF_2 @ CD Regal" [label="2.161"] "BASE_2" -> "SHELF_4 @ Toaster" [label="2.161"] "BASE_2" -> "SHELF_1 @ Chris" [label="2.040"] subgraph "cluster_SHELF_3 @ ra" { "SHELF_3 @ ra" } "SHELF_3 @ ra" -> "SHELF_5 @ Bar" [label="1.192"] "SHELF_3 @ ra" -> "SHELF_4 @ Toaster" [label="1.328"] "SHELF_3 @ ra" -> "BASE_2" [label="2.277"] subgraph "cluster_SHELF_4 @ Toaster" { "SHELF_4 @ Toaster" } "SHELF_4 @ Toaster" -> "SHELF_3 @ ra" [label="1.037"] "SHELF_4 @ Toaster" -> "SHELF_2 @ CD Regal" [label="1.483"] "SHELF_4 @ Toaster" -> "SHELF_5 @ Bar" [label="1.175"] "SHELF_4 @ Toaster" -> "SHELF_1 @ Chris" [label="1.371"] "SHELF_4 @ Toaster" -> "BASE_2" [label="3.446"] subgraph "cluster_SHELF_1 @ Chris" { "SHELF_1 @ Chris" } "SHELF_1 @ Chris" -> "SHELF_3 @ ra" [label="1.170"] "SHELF_1 @ Chris" -> "SHELF_5 @ Bar" [label="1.020"] subgraph "cluster_SHELF_5 @ Bar" { "SHELF_5 @ Bar" } "SHELF_5 @ Bar" -> "SHELF_3 @ ra" [label="1.045"] "SHELF_5 @ Bar" -> "SHELF_2 @ CD Regal" [label="1.393"] "SHELF_5 @ Bar" -> "SHELF_4 @ Toaster" [label="1.203"] "SHELF_5 @ Bar" -> "SHELF_1 @ Chris" [label="1.226"] "SHELF_5 @ Bar" -> "BASE_2" [label="2.898"] } The problem is, when pinging ANY of the clients from the base (or any client from any other client) I always have a package loss of roughly 50% with a ping reply time up to 10ms sometimes (BASE2 -> SHELF_1, the closer ones are faster). To make things worse, the connection is so weak, even a ssh login may bring it down. I tried quite a few different settings and already updated to the new version and used multiple USB sticks - the result always stays the same. Now I am out of ideas and I would appreciate some new ideas. GERMAN: Ich habe hier 5 Raspberries die sich gegenseitig sehen können (einer ist eine BASIS (BASE2), einer davon (SHELF_1) kann von der Basis nicht direkt gesehen werden, weil sie von einem raum zum nächsten immer größere Distanzen überwinden müssen). Das Problem ist nun, dass wenn ich irgend einen client von der Basis aus pinge, oder irgend einen client von einem anderen client pinge, dass ich rund 50% package loss mit bis zu 10ms antwortzeit habe. Die die sich näher sind funktionieren besser (2ms) die weiter weg sind schlechter. Ich kann nicht mal mit einer ssh konsole von BASE2 auf SHELF_1 so dass ich da sinnvoll was eingeben kann. Ich habe schon einige verschiedene Optionen durchprobiert, wie Beispielsweise Update von 2015.0 auf 2015.2, sogar zwei USB Sticks pro Raspberry PI, aber das Problem bleibt. Nun würde ich um Input bitten, mir sind die Ideen ausgegangen. Danke Thanks a lot! Richard
