Add a XFRM_STATE_AF_UNSPEC flag to handle the AF_UNSPEC behavior for
the selector family. Userspace applications can set this flag to leave
the selector family of the xfrm_state unspecified. This can be used
to to handle inter family tunnels if the selector is not set from
userspace.Signed-off-by: Steffen Klassert

Previously I added sessionid output to all audit messages where it was
available but we still didn't know the sessionid of the sender of
netlink messages. This patch adds that information to netlink messages
so we can audit who sent netlink messages.Signed-off-by: Eric Paris

Previously digest_null had no setkey function which meant that
we used hmac(digest_null) for IPsec since IPsec always calls
setkey. Now that digest_null has a setkey we no longer need to
do that.In fact when only confidentiality is specified for ESP we already
use digest_null directly. However, when the null algorithm is
explicitly specified by the user we still opt for hmac(digest_null).This patch removes this discrepancy. I have not added a new compat
name for it because by chance it wasn't actualy possible for the user
to specify the name hmac(digest_null) due to a key length check in
xfrm_user (which I found out when testing that compat name :)Signed-off-by: Herbert Xu

As it stands it's impossible to use any authentication algorithms
with an ID above 31 portably. It just happens to work on x86 but
fails miserably on ppc64.The reason is that we're using a bit mask to check the algorithm
ID but the mask is only 32 bits wide.After looking at how this is used in the field, I have concluded
that in the long term we should phase out state matching by IDs
because this is made superfluous by the reqid feature. For current
applications, the best solution IMHO is to allow all algorithms when
the bit masks are all ~0.The following patch does exactly that.
This bug was identified by IBM when testing on the ppc64 platform
using the NULL authentication algorithm which has an ID of 251.Signed-off-by: Herbert Xu

The xfrm_get_policy() and xfrm_add_pol_expire() put some rather large structs
on the stack to work around the LSM API. This patch attempts to fix that
problem by changing the LSM API to require only the relevant "security"
pointers instead of the entire SPD entry; we do this for all of the
security_xfrm_policy*() functions to keep things consistent.Signed-off-by: Paul Moore

Commit df9dcb45 ([IPSEC]: Fix inter address family IPsec tunnel handling)
broke openswan by removing the selector initialization for tunnel mode
in case it is uninitialized.This patch restores the initialization, fixing openswan, but probably
breaking inter-family tunnels again (unknown since the patch author
disappeared). The correct thing for inter-family tunnels is probably
to simply initialize the selector family explicitly.Signed-off-by: Patrick McHardy

Each MIPv6 XFRM state (DSTOPT/RH2) holds either destination or source
address to be mangled in the IPv6 header (that is "CoA").
On Inter-MN communication after both nodes binds each other,
they use route optimized traffic two MIPv6 states applied, and
both source and destination address in the IPv6 header
are replaced by the states respectively.
The packet format is correct, however, next-hop routing search
are not.
This patch fixes it by remembering address pairs for later states.Based on patch from Masahide NAKAMURA .

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

using the new algorithm payload type XFRMA_ALG_AEAD. Each algorithms
