Now that the flowcache is removed we need to generate
a new dummy bundle every time we check if the needed
SAs are in place because the dummy bundle is not cached
anymore. Fix it by passing the XFRM_LOOKUP_QUEUE flag
to xfrm_lookup(). This makes sure that we get a dummy
bundle in case the SAs are n
We don't have a compat layer for xfrm, so userspace and kernel

a broken configuration, so refuse to configure socket policies

When IPsec offloading was introduced, we accidentally incremented
the sequence number counter on the xfrm_state by one packet
too much in the ESN case. This leads to a sequence number gap of

May be the better way would be to change how "all"/"any" argument behaves? My
original concern was about "default" only. I agree too, that "all" or "any"
should work for all routes. But not for the default.

Here is a series of fixes to issues that occur when SACK is not

remote corner cases of recovery but many/almost all recoveries
without SACK will be impacted by one (or even more than one) of
them. The sender-side changes (1-4) are not m
When a cumulative ACK lands to high_seq at the end of loss
recovery and SACK is not enabled, the sender needs to avoid
false fast retransmits (RFC6582). The avoidance mechanisms is
implemented by remaining in the loss recovery CA state until
one additional cumulative ACK arrives. During the operati
If SACK is not enabled and the first cumulative ACK after the RTO

So you start off with something like:
#define min(x, y) __min_max(x, <, y)
#define max(x, y) __min_max(x, >, y)
then have:
#define __min_max(x, cond, y) ((x) cond (y) ? (x) : (y))

That's a bit extreme. There is a race condition bug that needs fixing.
