Jakub Kicinski 5b4b62a169 rtnetlink: make the "split" NLM_DONE handling generic ... Jaroslav reports Dell's OMSA Systems Management Data Engine expects NLM_DONE in a separate recvmsg(), both for rtnl_dump_ifinfo() and inet_dump_ifaddr(). We already added a similar fix previously in commit 460b0d33cf ("inet: bring NLM_DONE out to a separate recv() again") Instead of modifying all the dump handlers, and making them look different than modern for_each_netdev_dump()-based dump handlers - put the workaround in rtnetlink code. This will also help us move the custom rtnl-locking from af_netlink in the future (in net-next). Note that this change is not touching rtnl_dump_all(). rtnl_dump_all() is different kettle of fish and a potential problem. We now mix families in a single recvmsg(), but NLM_DONE is not coalesced. Tested: ./cli.py --dbg-small-recv 4096 --spec netlink/specs/rt_addr.yaml \ --dump getaddr --json '{"ifa-family": 2}' ./cli.py --dbg-small-recv 4096 --spec netlink/specs/rt_route.yaml \ --dump getroute --json '{"rtm-family": 2}' ./cli.py --dbg-small-recv 4096 --spec netlink/specs/rt_link.yaml \ --dump getlink Fixes: 3e41af9076 ("rtnetlink: use xarray iterator to implement rtnl_dump_ifinfo()") Fixes: cdb2f80f1c ("inet: use xa_array iterator to implement inet_dump_ifaddr()") Reported-by: Jaroslav Pulchart <jaroslav.pulchart@gooddata.com> Link: https://lore.kernel.org/all/CAK8fFZ7MKoFSEzMBDAOjoUt+vTZRRQgLDNXEOfdCCXSoXXKE0g@mail.gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> Reviewed-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S.
