ipv4: Fix "Set rt->rt_iif more sanely on output routes."

2011-04-07T21:04:08+00:00

Commit 1018b5c01636c7c6bda31a719bda34fc631db29a ("Set rt->rt_iif more sanely on output routes.") breaks rt_is_{output,input}_route. This became the cause to return "IP_PKTINFO's ->ipi_ifindex == 0". To fix it, this does: 1) Add "int rt_route_iif;" to struct rtable 2) For input routes, always set rt_route_iif to same value as rt_iif 3) For output routes, always set rt_route_iif to zero. Set rt_iif as it is done currently. 4) Change rt_is_{output,input}_route() to test rt_route_iif Signed-off-by: OGAWA Hirofumi Signed-off-by: David S. Miller

route: Take the right src and dst addresses in ip_route_newports

2011-03-25T08:28:45+00:00

When we set up the flow informations in ip_route_newports(), we take the address informations from the the rt_key_src and rt_key_dst fields of the rtable. They appear to be empty. So take the address informations from rt_src and rt_dst instead. This issue was introduced by commit 5e2b61f78411be25f0b84f97d5b5d312f184dfd1 ("ipv4: Remove flowi from struct rtable.")

ipv4: fix route deletion for IPs on many subnets

2011-03-22T08:06:32+00:00

Alex Sidorenko reported for problems with local routes left after IP addresses are deleted. It happens when same IPs are used in more than one subnet for the device. Fix fib_del_ifaddr to restrict the checks for duplicate local and broadcast addresses only to the IFAs that use our primary IFA or another primary IFA with same address. And we expect the prefsrc to be matched when the routes are deleted because it is possible they to differ only by prefsrc. This patch prevents local and broadcast routes to be leaked until their primary IP is deleted finally from the box. As the secondary address promotion needs to delete the routes for all secondaries that used the old primary IFA, add option to ignore these secondaries from the checks and to assume they are already deleted, so that we can safely delete the route while these IFAs are still on the device list.

net: Make flowi ports AF dependent.

2011-03-12T23:08:46+00:00

Create two sets of port member accessors, one set prefixed by fl4_* and the other prefixed by fl6_* This will let us to create AF optimal flow instances. It will work because every context in which we access the ports, we have to be fully aware of which AF the flowi is anyways. Signed-off-by: David S. Miller

net: Put flowi_* prefix on AF independent members of struct flowi

2011-03-12T23:08:44+00:00

I intend to turn struct flowi into a union of AF specific flowi structs. There will be a common structure that each variant includes first, much like struct sock_common. This is the first step to move in that direction. Signed-off-by: David S. Miller

ipv4: Create and use route lookup helpers.

The idea here is this minimizes the number of places one has to edit in order to make changes to how flows are defined and used. Signed-off-by: David S. Miller

ipv4: Remove flowi from struct rtable.

2011-03-05T05:55:31+00:00

The only necessary parts are the src/dst addresses, the interface indexes, the TOS, and the mark. The rest is unnecessary bloat, which amounts to nearly 50 bytes on 64-bit. Signed-off-by: David S. Miller

ipv4: Use passed-in protocol in ip_route_newports().
