[PATCH net-next v6 00/11] net: Improve netns handling in rtnetlink
by Xiao Liang 19 Dec '24

19 Dec '24

This patch series includes some netns-related improvements and fixes for rtnetlink, to make link creation more intuitive: 1) Creating link in another net namespace doesn't conflict with link names in current one. 2) Refector rtnetlink link creation. Create link in target namespace directly. 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 01 servers for 1) to avoids link name conflict in different netns. To achieve 2), there're mainly 3 steps: - Patch 02 packs newlink() parameters into a struct, including the original "src_net" along with more netns context. - Patch 03 ~ 07 converts device drivers to use the explicit netns extracted from params. - Patch 08 ~ 09 removes the old netns parameter, and converts rtnetlink to create device in target netns directly. Patch 10 ~ 11 adds some tests for link name and link netns. BTW please note there're some issues found in current code: - In amt_newlink() drivers/net/amt.c: amt->net = net; ... amt->stream_dev = dev_get_by_index(net, ... Uses net, but amt_lookup_upper_dev() only searches in dev_net. So the AMT device may not be properly deleted if it's in a different netns from lower dev. - In gtp_newlink() in drivers/net/gtp.c: gtp->net = src_net; ... gn = net_generic(dev_net(dev), gtp_net_id); list_add_rcu(&gtp->list, &gn->gtp_dev_list); Uses src_net, but priv is linked to list in dev_net. So it may not be properly deleted on removal of link netns. - In pfcp_newlink() in drivers/net/pfcp.c: pfcp->net = net; ... pn = net_generic(dev_net(dev), pfcp_net_id); list_add_rcu(&pfcp->list, &pn->pfcp_dev_list); Same as above. - In lowpan_newlink() in net/ieee802154/6lowpan/core.c: wdev = dev_get_by_index(dev_net(ldev), nla_get_u32(tb[IFLA_LINK])); Looks for IFLA_LINK in dev_net, but in theory the ifindex is defined in link netns. --- v6: - Split prototype, driver and rtnetlink changes. - Add more tests for link netns. - Fix IPv6 tunnel net overwriten in ndo_init(). - Reorder variable declarations. - Exclude a ip_tunnel-specific patch. v5: link: https://lore.kernel.org/all/20241209140151.231257-1-shaw.leon@gmail.com/ - Fix function doc in batman-adv. - Include peer_net in rtnl newlink parameters. v4: link: https://lore.kernel.org/all/20241118143244.1773-1-shaw.leon@gmail.com/ - Pack newlink() parameters to a single struct. - Use ynl async_msg_queue.empty() in selftest. v3: link: https://lore.kernel.org/all/20241113125715.150201-1-shaw.leon@gmail.com/ - Drop "netns_atomic" flag and module parameter.

[PATCH] batman-adv: Map VID 0 to untagged TT VLAN
by Sven Eckelmann 18 Dec '24

18 Dec '24

VID 0 is not a valid VLAN according to "802.1Q-2011" "Table 9-2—Reserved VID values". It is only used to indicate "priority tag" frames which only contain priority information and no VID. The 8021q is also redirecting the priority tagged frames to the underlying interface since commit ad1afb003939 ("vlan_dev: VLAN 0 should be treated as "no vlan tag" (802.1p packet)"). But at the same time, it automatically adds the VID 0 to all devices to ensure that VID 0 is in the allowed list of the HW filter. This resulted in a VLAN 0 which was always announced in OGM messages. batman-adv should therefore not create a new batadv_softif_vlan for VID 0 and handle all VID 0 related frames using the "untagged" global/local translation tables.

[PATCH v3 0/3] add dynamic, bridged-in TT VID detection support
by Linus Lüssing 02 Dec '24

02 Dec '24

For one thing the following patchest is supposed to mitigate the regression of extra OGM overhead that we accidentally introduced with the introduction of the compatibility version 15, the TVLV support it provided, together with TT VLAN support. The addition of these TVLVs roughly doubled the OGM overhead back then, also/mainly because the 8021q and Linux bridge modules would add TT VLAN IDs 0 and 1, even if no one is actually using them. PATCH 3/3 tries to avoid this and will only add these two VLAN IDs if they were detected on actual traffic. In preparation of this the internal VLAN creation was overhauled in PATCH 1/3. This also in theory allows detecting new VLAN IDs dynamically from traffic from bridged-in traffic. So far, VLAN IDs could only be used which were anticipated and configured on top of bat0 by the administrator. However the detection of VLANs from bridged-in clients is by default disabled for now through PATCH 2/3. This patch adds a configurable limit for such snooped VLAN IDs, defaulting to zero for now. The issue is that each added VLAN still increases the OGM size considerably in the current protocol, so it is not advised to add many VLANs at the moment, without a bigger upgrade of the protocol. Also there is still an outstanding issue with temporarily broken broadcast traffic upon adding a new VLAN if BLA is enabled at the same time. Therefore defaulting to zero snooped VLANs from bridged-in clients for now. Regards, Linus --- v3: * fixing refcounting, removing an unnecessary kref_get() in PATCH 1/3 * adding PATCH 2/3 + PATCH 3/3 * resubmitting without the RFC tag v2: fix a typo, a missing "to" in the commit message

[PATCH v7 0/3] batman-adv: increase DAT DHT timeout
by Linus Lüssing 29 Nov '24

29 Nov '24

This patchset increases 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 split into two separate hash tables (PATCH 2/3).

[PATCH v5 0/2] batman-adv: increase DAT DHT timeout
by Linus Lüssing 29 Nov '24

29 Nov '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.

[PATCH v3 0/5] batman-adv: TT change events fixes and improvements
by Remi Pommarel 25 Nov '24

25 Nov '24

The first three patches are actual fixes. The first two try to avoid sending uninitialized data that could be interpreted as invalid TT change events in both TT change response 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 third 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 more cleanup / potential slight improvements. While patch 4 is mainly cosmetic (having negative tt.local_changes values is not exactly an issue), patch 5 is here to keep the TT changes list as short as possible (reducing network overhead). V4: - Reword comment on patch 4 - Fix flag assignment position is patch 4 - Fix store stearing with WRITE_ONCE - Change tt.local_change < 1 to tt.local_change == 0 in patch 4 - Rework/simplify TT event deduplication logic V3: - Fix commit message wording - Update outdated comments V2: - This has been tested enough to not be in RFC state anymore - Add one more uninitialize TT change fix for full table TT responses Remi Pommarel (5): batman-adv: Do not send uninitialized TT changes batman-adv: Remove uninitialized data in full table TT response batman-adv: Do not let TT changes list grows indefinitely batman-adv: Remove atomic usage for tt.local_changes batman-adv: Don't keep redundant TT change events net/batman-adv/soft-interface.c | 2 +- net/batman-adv/translation-table.c | 123 ++++++++++++++++------------- net/batman-adv/types.h | 4 +- 3 files changed, 72 insertions(+), 57 deletions(-) -- 2.40.0
