So, change icmp(v6)_sk creation/disposal to the scheme used in the netlink for rtnl, i.e. create a socket in the context of the init_net and assign the namespace without getting a referrence later. Also use sk_release_kernel instead of sock_release to properly destroy such sockets. Signed-off-by:

This staff will be needed for non-netlink kernel sockets, which should also not pin a namespace like tcp_socket and icmp_socket. Signed-off-by:

Own __icmp(v6)_sk should be present in each namespace. So, it should be allocated dynamically. Though, alloc_percpu does not fit the case as it implies additional dereferrence for no bonus. Allocate data for pointers just like __percpu_alloc_mask does and place pointers to struct sock into this array. Signed-off-by:

We have to get socket lock inside icmp(v6)_xmit_lock/unlock. The socket is get from global variable now. When this code became namespaces, one should pass a namespace and get socket from it. Though, above is useless. Socket is available in the caller, just pass it inside. This saves a bit of code now and saves more later. add/remove: 0/0 grow/shrink: 1/3 up/down: 1/-169 (-168) function old new delta icmp_rcv 718 719 +1 icmpv6_rcv 2343 2303 -40 icmp_send 1566 1518 -48 icmp_reply 549 468 -81 Signed-off-by:

Basically, there is no difference, what to store: socket or sock. Though, sock looks better as there will be 1 less dereferrence on the fast path. Signed-off-by:

icmp_init could fail and this is normal for namespace other than initial. So, the panic should be triggered only on init_net initialization path. Additionally create rollback path for icmp_init as a separate function. It will also be used later during namespace destruction. Signed-off-by:

struct net_proto_family* is not used in icmp[v6]_init, ndisc_init, igmp_init and tcp_v4_init. Remove it. Signed-off-by:

Change xfrm_policy and xfrm_state walking algorithm from O(n^2) to O(n). This is achieved adding the entries to one more list which is used solely for walking the entries. This also fixes some races where the dump can have duplicate or missing entries when the SPD/SADB is modified during an ongoing dump. Dumping SADB with 20000 entries using "time ip xfrm state" the sys time dropped from 1.012s to 0.080s. Signed-off-by:

Skip the prefix length matching in source address selection for orchid -> non-orchid addresses. Overlay Routable Cryptographic Hash IDentifiers (RFC 4843, 2001:10::/28) are currenty not globally reachable. Without this check a host with an ORCHID address can end up preferring those over regular addresses when talking to other regular hosts in the 2001::/16 range thus breaking non-orchid connections.

Add a new label for Overlay Routable Cryptographic Hash Identifiers (RFC 4843) prefix 2001:10::/28 to help proper source address selection. ORCHID addresses are used by for example Host Identity Protocol. They are global and routable, but they currently need support from both endpoints and therefore mixing regular and ORCHID addresses for source and destination is a bad idea in general case.

This is a callback registered to inet address notifier chain. The check is useless as: - ifa->ifa_dev is always != NULL - similar checks are abscent in all other notifiers. Signed-off-by:
