[PATCH net-next v3 0/6] net: Improve netns handling in RTNL and ip_tunnel
by Xiao Liang 15 Nov '24

15 Nov '24

This patch series includes some netns-related improvements and fixes for RTNL and ip_tunnel, to make link creation more intuitive: - Creating link in another net namespace doesn't conflict with link names in current one. - Refector rtnetlink link creation. Create link in target namespace directly. Pass both source and link netns to drivers via newlink() callback. So that # ip link add netns ns1 link-netns ns2 tun0 type gre ... will create tun0 in ns1, rather than create it in ns2 and move to ns1. And don't conflict with another interface named "tun0" in current netns. Patch 1 from Donald is included just as a dependency. --- v3: - Drop "netns_atomic" flag and module parameter.

[RFC PATCH 0/4] batman-adv: TT change events fixes and improvements
by Remi Pommarel 01 Nov '24

01 Nov '24

The first two patches are actual fixes. The first one tries to avoid sending uninitialized data that could be interpreted as invalid TT change events in both TT request and OGM. Following invalid entries could be seen when that happen with batctl o: * 00:00:00:00:00:00 -1 [....] ( 0) 88:12:4e:ad:7e:ba (179) (0x45845380) * 00:00:00:00:78:79 4092 [.W..] ( 0) 88:12:4e:ad:7e:3c (145) (0x8ebadb8b) The second one fixes an issue that happened when a TT change event list is too big for the MTU, the list was never actually sent nor free and continued to grow indefinitely from this point. That also caused the OGM TTVN to increase at each OGM interval without any changes being ever visible to other nodes. This ever growing TT change event list could be observed by looking at /sys/kernel/slab/batadv_tt_change_cache/objects that sometimes showed unusal high value even after issuing a memcache shrink. The next two patches are potential slight improvements. While patch 3 is mainly cosmetic (having negative tt.local_changes value is not exactly an issue), patch 4 is here to keep the TT changes list as short as possible.

[PATCH v5 0/2] batman-adv: increase DAT DHT timeout
by Linus Lüssing 28 Oct '24

28 Oct '24

Hi, This is the fifth itereation to increase the DAT DHT timeout to reduce the amount of broadcasted ARP Replies. To increase the timeout only for DAT DHT entries added via DHT-PUT but not for any other entry in the DAT cache the DAT cache and DAT DHT concepts are first split into two separate hash tables (PATCH 1/2). PATCH 2/2 then increases the timeout for DAT DHT entries from 5 to 30 minutes. The motivation for this patchset is based on the observations made here: https://www.open-mesh.org/projects/batman-adv/wiki/DAT_DHCP_Snooping In tests this year at Freifunk Lübeck with ~180 mesh nodes and Gluon this reduced the ARP broadcast overhead, measured over 7 days, as follows: - Total: 6677.66 bits/s -> 677.26 bits/s => -89.86% 11.92 pkts/s -> 1.21 pkts/s => -89.85% - from gateways: 5618.02 bits/s -> 212.28 => -96.22% 10.03 pkts/s -> 0.38 pkts/s => -96.21% Also see graphics and a few more test details here: - https://www.open-mesh.org/projects/batman-adv/wiki/DAT_DHCP_Snooping#Result… These patches have been applied in this mesh network without issues for 3 months now. Regards, Linus --- Changelog v5: - rebased to current main branch -> removed now obsolete debugfs code Changelog v4: - rebased to: acfc9a214d01695 ("batman-adv: genetlink: make policy common to family") Changelog v3: formerly: "batman-adv: Increase purge timeout on DAT DHT candidates" https://patchwork.open-mesh.org/patch/17728/ - fixed the potential jiffies overflow and jiffies initialization issues by replacing the last_dht_update timeout variable with a split of DAT cache and DAT DHT into two separate hash tables -> instead of maintaining two timeouts in one DAT entry two DAT entries are created and maintained in their respective DAT cache and DAT DHT hash tables Changelog v2: formerly: "batman-adv: Increase DHCP snooped DAT entry purge timeout in DHT" (https://patchwork.open-mesh.org/patch/17364/) - removed the extended timeouts flag in the DHT-PUT messages introduced in v1 again - removed DHCP dependency

[PATCH 0/1] batctl: ping: Add millisecond precision to ping interval
by Noah Peterson 20 Oct '24

20 Oct '24

There is a minor issue with using the new `nanosleep()` function: When compiling with the `sys/time.h` header instead of `time.h`, a warning is thrown about `nanosleep()` being implicitly declared when it is called on line 309. This can be fixed by adding the `nanosleep()` prototype to ping.c, but this triggers the warning "externs should be avoided in .c files" from `checkpatch.pl`. Is there a third and better option, or should it be left as-is?

[PATCH] batman-adv: mcast: add option to forward MLD reports only to mcast routers
by Linus Lüssing 07 Oct '24

07 Oct '24

In most setups it is sufficient for us to only send MLD reports to nodes which have a multicast router attached. Which reduces overall overhead, especially in large batman-adv mesh networks, where broadcasts are particularly undesirable. However there is one specific, known issue / broken scenario with this setting: If the IGMP/MLD querier is configured directly on the bridge on top of bat0. But there is no multicast router on or behind this node. Then this bridge will be unable to detect multicast listeners on/behind other nodes which have the MLD-RTR-ONLY setting enabled. (A workaround for this can then in turn be to set multicast_router=2 on the bat0 bridge port on the node with the IGMP/MLD querier.) Therefore MLD report flooding is kept the default and MLD report to multicast routers only forwarding is considered experimental and warned about. Signed-off-by: Linus Lüssing <linus.luessing(a)c0d3.blue> --- An list of scenarios with illustrations and a step-by-step evaluation with this setting for them can be found on the batman-adv wiki: * https://www.open-mesh.org/projects/batman-adv/wiki/Multicast-IGMP-MLD-Repor… This patchset is applied and tested on/between Freifunk Lübeck (180 nodes) and a small Freifunk Vogtland domain. It allowed using layer 3 IPv6 multicast routing here without flooding the whole mesh network with MLD reports. include/uapi/linux/batman_adv.h | 9 ++++++ net/batman-adv/multicast.c | 52 +++++++++++++++++++++++++-------- net/batman-adv/netlink.c | 17 +++++++++++ net/batman-adv/soft-interface.c | 1 + net/batman-adv/types.h | 7 +++++ 5 files changed, 74 insertions(+), 12 deletions(-) diff --git a/include/uapi/linux/batman_adv.h b/include/uapi/linux/batman_adv.h index 35dc016c9bb4..11cd170036ff 100644 --- a/include/uapi/linux/batman_adv.h +++ b/include/uapi/linux/batman_adv.h @@ -481,6 +481,15 @@ enum batadv_nl_attrs { */ BATADV_ATTR_MULTICAST_FANOUT, + /** + * @BATADV_ATTR_MULTICAST_MLD_RTR_ONLY_ENABLED: defines how IGMP/MLD + * reports are forwarded in the mesh.

[PATCH] batman-adv: Use string choice helper to print booleans
by Sven Eckelmann 06 Oct '24

06 Oct '24

The commit ea4692c75e1c ("lib/string_helpers: Consolidate string helpers implementation") introduced common helpers to print string representations of boolean helpers. These are supposed to be used instead of open coded versions.
