ipv6/addrlabel: fix ip6addrlbl_get()

2016-01-29T21:12:57Z

commit e459dfeeb64008b2d23bdf600f03b3605dbb8152 upstream. ip6addrlbl_get() has never worked. If ip6addrlbl_hold() succeeded, ip6addrlbl_get() will exit with '-ESRCH'. If ip6addrlbl_hold() failed, ip6addrlbl_get() will use about to be free ip6addrlbl_entry pointer. Fix this by inverting ip6addrlbl_hold() check.

ipv6 netns: Address labels per namespace

2008-06-11T17:38:15Z

This pacth makes IPv6 address labels per network namespace. It keeps the global label tables, ip6addrlbl_table, but adds a 'net' member to each ip6addrlbl_entry. This new member is taken into account when matching labels. Changelog ========= * v1: Initial version * v2: * Minize the penalty when network namespaces are not configured: * the 'net' member is added only if CONFIG_NET_NS is defined. This saves space when network namespaces are not configured. * 'net' value is retrieved with the inlined function ip6addrlbl_net() that always return &init_net when CONFIG_NET_NS is not defined. * 'net' member in ip6addrlbl_entry renamed to the less generic 'lbl_net' name (helps code search).

[NET] NETNS: Omit sock->sk_net without CONFIG_NET_NS.

2008-03-25T19:39:55Z

Introduce per-sock inlines: sock_net(), sock_net_set() and per-inet_timewait_sock inlines: twsk_net(), twsk_net_set(). Without CONFIG_NET_NS, no namespace other than &init_net exists. Let's explicitly define them to help compiler optimizations. Signed-off-by: YOSHIFUJI Hideaki

[IPV6]: Add ORCHID prefix to address label table

2008-02-29T04:55:02Z

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.

[IPV6] ADDRLABEL: Fix double free on label deletion.

2008-01-28T23:46:02Z

If an entry is being deleted because it has only one reference, we immediately delete it and blindly register the rcu handler for it, This results in oops by double freeing that object. This patch fixes it by consolidating the code paths for the deletion; let its rcu handler delete the object if it has no more reference.

[NET]: Make rtnetlink infrastructure network namespace aware (v3)

2008-01-28T22:54:25Z

After this patch none of the netlink callback support anything except the initial network namespace but the rtnetlink infrastructure now handles multiple network namespaces.
