[PATCH] selftests/bpf: Fix compilation error in get_uprobe_offset()

by Jerome Marchand

In get_uprobe_offset(), the call to procmap_query() use the constant PROCMAP_QUERY_VMA_EXECUTABLE, even if PROCMAP_QUERY is not defined. Define PROCMAP_QUERY_VMA_EXECUTABLE when PROCMAP_QUERY isn't.

[PATCH net-next v6 00/11] net: Improve netns handling in rtnetlink

by Xiao Liang

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 net] selftests: openvswitch: fix tcpdump execution

by Adrian Moreno

Fix the way tcpdump is executed by: - Using the right variable for the namespace. Currently the use of the empty "ns" makes the command fail. - Waiting until it starts to capture to ensure the interesting traffic is caught on slow systems. - Using line-buffered output to ensure logs are available when the test is paused with "-p". Otherwise the last chunk of data might only be written when tcpdump is killed.
