While this change results in the correct add/update flag during installation,
it exchanges all other values in the child_sa->install() call. We should pass
the correct flag, but determine the add/update flag by other means.
This reverts commit e722ee5d.
The inbound flag is used to determine if we have to install an update or a new
SA in the kernel. As we do not have allocated SPIs and therefore can't update
an existing SA in the HA plugin, always set the flag to FALSE.
Before 698ed656 we had extra logic for that case, but handling it directly in
the HA plugin is simpler.
As we now use the same reqid for multiple CHILD_SAs with the same selectors,
having marks based on the reqid makes not that much sense anymore. Instead we
use unique marks that use a custom identifier. This identifier is reused during
rekeying, keeping the marks constant for any rule relying on it (for example
installed by updown).
This also simplifies handling of reqid allocation, as we do not have to query
the marks that is not yet assigned for an unknown reqid.
When rekey_child_sa is called while enumerating the children of an IKE_SA, and
the child to be rekeyed is redundant a QUICK_DELETE task is queued instead of a
QUICK_MODE task. This alters the IKE_SA's list of children (ike_sa_t::child_sas)
invalidating the current element of the child_sa_enumerator. The enumerate
function of linked_list_t will then advance to an element with unpredictable
contents most likely resulting in an segmentation violation. A similar behavior
should be observed when delete_child_sa is called.
This patch creates a list of protocol/spi values while holding the
child_sa_enumerator and performs the rekeying (deletion of redundant) chlidren
after releasing the enumerator.

The adopt_children_job_create() function is not available when IKEv1 support
is disabled. Fixes uncommon builds using --enable-ha --disable-ikev1.
Fixes#690.
This currently has no effect: We don't include AEAD algorithms in the default
ESP proposal, as we don't know if it is supported by the backend. But as we
hopefully get an algorithm query mechanism on kernel interfaces some day, we
add the appropriate functionality nonetheless.
Due to the previous negation the high bits of the mask were set, which
at least some versions of the Android build system prevent with a compile-time
check.
Replace the allowany semantic by a more powerful subnet and IP range matching.
Multiple addresses, DNS names, subnets and ranges can be specified in a comma
separated list. Initiators ignore the ranges/subnets, responders match
configurations against all addresses, ranges and subnets.
INCLUDES are now deprecated and throw warnings when using automake 1.13.
We now also differentiate AM_CPPFLAGS and AM_CFLAGS, where includes and
defines are passed to AM_CPPFLAGS only.
e0efd7c1 switches to automated job rescheduling for HA heartbeat. However,
send_status() is initially called directly, which will not reschedule the job
as required.
If the provider has access to the full pool list, it can enumerate
them twice, for example to search for existing leases first, and
only search for new leases in a second step.
Fixes lease enumeration in attr-sql using multiple pools.
