On powerpc, a CPU does not necessarily originate from NUMA node 0.
This contrasts with architectures like x86, where CPU 0 is not
hot-pluggable, making NUMA node 0 a consistently valid node.
This discrepancy can lead to failures when creating a map on NUMA
node 0, which is initialized by default, if no CPUs are allocated
from NUMA node 0.

This patch fixes the issue by setting NUMA_NO_NODE (-1) for map

selftests: net: test for lwtunnel dst ref loops 2025-03-20T10:25:52+00:00 Justin Iurman justin.iurman@uliege.be 2025-03-14T12:00:48+00:00 3ed61b8938c66680e13a1d1929afb9b145c26a86 As recently specified by commit 0ea09cbf8350 ("docs: netdev: add a note on selftest posting") in net-next, the selftest is therefore shipped in this series. However, this selftest does not really test this series. It needs this series to avoid crashing the kernel. What it really tests, thanks to kmemleak, is what was fixed by the following commits: - commit c71a192976de ("net: ipv6: fix dst refleaks in rpl, seg6 and ioam6 lwtunnels") - commit 92191dd10730 ("net: ipv6: fix dst ref loops in rpl, seg6 and ioam6 lwtunnels") - commit c64a0727f9b1 ("net: ipv6: fix dst ref loop on input in seg6 lwt") - commit 13e55fbaec17 ("net: ipv6: fix dst ref loop on input in rpl lwt") - commit 0e7633d7b95b ("net: ipv6: fix dst ref loop in ila lwtunnel") - commit 5da15a9c11c1 ("net: ipv6: fix missing dst ref drop in ila lwtunnel") Signed-off-by: Justin Iurman <justin.iurman@uliege.be> Link: https://patch.msgid.link/20250314120048.12569-4-justin.iurman@uliege.be Signed-off-by: Paolo Abeni <pabeni@redhat.com>
