[PATCH net-next v8 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 serves 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. No semantic changes are introduced. - 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. Kuniyuki has a patchset to address the issues of gtp and pfcp: https://lore.kernel.org/netdev/20250110014754.33847-1-kuniyu@amazon.com/ --- v8: - Move dev and ext_ack out from param struct. - Validate link_net and dev_net are identical for 6lowpan. v7: link: https://lore.kernel.org/all/20250104125732.17335-1-shaw.leon@gmail.com/ - Add selftest kconfig. - Remove a duplicated test of ip6gre. v6: link: https://lore.kernel.org/all/20241218130909.2173-1-shaw.leon@gmail.com/ - 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 v4 0/8] Basic SEV-SNP Selftests

by Pratik R. Sampat

This patch series extends the sev_init2 and the sev_smoke test to exercise the SEV-SNP VM launch workflow. Primarily, it introduces the architectural defines, its support in the SEV library and extends the tests to interact with the SEV-SNP ioctl() wrappers. Patch 1 - Do not advertize SNP on incompatible firmware Patch 2 - SNP test for KVM_SEV_INIT2 Patch 3 - Add VMGEXIT helper Patch 4 - Introduce SEV+ VM type check Patch 5 - SNP iotcl() plumbing for the SEV library Patch 6 - Force set GUEST_MEMFD for SNP Patch 7 - Cleanups of smoke test - Decouple policy from type Patch 8 - SNP smoke test v4: 1. Remove SNP FW API version check in the test and ensure the KVM capability advertizes the presence of the feature. Retain the minimum version definitions to exercise these API versions in the smoke test. 2. Retained only the SNP smoke test and SNP_INIT2 test 3. The SNP architectural defined merged with SNP_INIT2 test patch 4. SNP shutdown merged with SNP smoke test patch 5. Add SEV VM type check to abstract comparisons and reduce clutter 6. Define a SNP default policy which sets bits based on the presence of SMT 7. Decouple privatization and encryption for it to be SNP agnostic 8. Assert for only positive tests using vm_ioctl() 9. Dropped tested-by tags In summary - based on comments from Sean, I have primarily reduced the scope of this patch series to focus on breaking down the SNP smoke test patch (v3 - patch2) to first introduce SEV-SNP support and use this interface to extend the sev_init2 and the sev_smoke test. The rest of the v3 patchset that introduces ioctl, pre fault, fallocate and negative tests, will be re-worked and re-introduced subsequently in future patch series post addressing the issues discussed. v3: https://lore.kernel.org/kvm/20240905124107.6954-1-pratikrajesh.sampat@amd.c… 1. Remove the assignments for the prefault and fallocate test type enums. 2. Fix error message for sev launch measure and finish. 3.

[PATCH] kunit: Introduce autorun option

by Stanislav Kinsburskii

The new option controls tests run on boot or module load. With the new debugfs "run" dentry allowing to run tests on demand, an ability to disable automatic tests run becomes a useful option in case of intrusive tests. The option is set to true by default to preserve the existent behavior. It can be overridden by either the corresponding module option or by the corresponding config build option.
