Tobias Brunner 2e2feffb67 Don't check interface of inbound message if interfaces are not filtered 
We don't have a proper kernel-net interface on Android yet, so the check
for a usable interface does not work there.

Tobias Brunner c6b401581a Changed how kernel-netlink handles virtual IP addresses 
Also tried to avoid the use of enumerators.
 2012-09-21 18:16:26 +02:00
Tobias Brunner 4106aea8e4 Made IP address enumeration more flexible 
Also added an option to enumerate addresses on ignored interfaces.

Tobias Brunner 940e1b0f66 Filter ignored interfaces in kernel interfaces (for events, address enumeration, etc.) 2012-09-21 18:16:26 +02:00

Tobias Brunner 9ba36c0f7f Make it easy to check if an address is locally usable via changed get_interface() method 2012-09-21 18:16:26 +02:00
Tobias Brunner aed33805ce Don't ignore loopback devices and allow addresses on them being enumerated 2012-09-21 18:16:26 +02:00
Tobias Brunner 9513225e6b Added options and a lookup function that will allow filtering of network interfaces 2012-09-21 18:16:26 +02:00
Tobias Brunner dad6d904ee Use source address in get_nexthop() call 
Otherwise the nexthop returned might belong to a different route than
the one actually used with the current source address.
 2012-09-21 18:16:25 +02:00
Tobias Brunner 662534657f Source address lookup refactored 
Routes matching the destination are now first parsed and sorted by network
prefix length.  This list is then used to search for the best route with
a matching preferred source address (if one is specified).  This makes sure
we really check all routes for that address.
 2012-09-21 18:16:25 +02:00
Tobias Brunner cef0a8118e Check routes with equal prefix if preferred source is specified 2012-09-21 18:16:25 +02:00
Tobias Brunner 9d6b02d6c1 Try to find preferred source on interface if returned source does not match 2012-09-21 18:16:25 +02:00
Tobias Brunner da6d86dd94 Try to keep the given source address when looking up routes 
This allows to pin the local end of an IKE_SA to an address that is not the
physical address of an interface.  Without this patch the local address would
change to the physical address when roam events occur.

Martin Willi 5b96503e13 Use uintptr_t in mem pool to avoid compiler warning if sizeof(void*) != sizeof(int) 2012-09-12 13:19:52 +02:00
Martin Willi 1e04488f32 Check for an existing lease in all stroke pools before creating a new one 2012-09-11 16:18:28 +02:00
Martin Willi 28a3d5bfbd Pass full pool list to release_address 2012-09-11 16:18:28 +02:00
Martin Willi 594c58e111 Pass the full list of pools to acquire_address, enumerate in providers 
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.

Tobias Brunner 4065e2504c Use the proper types for comma separated attributes read from strongswan.conf 
Attributes of different address families previously were mapped to
the same attribute type (the one derived from the address family of the
first address).
 2012-09-10 15:17:17 +02:00
Tobias Brunner 747fd544a7 Properly remove broadcast address from mem pools 2012-09-10 11:44:18 +02:00
Martin Willi 7f52f621c2 Be less verbose if IP allocation for a single pool fails 2012-08-30 16:43:44 +02:00
Martin Willi 40e9089889 Strictly enforce address family match while acquiring mem_pool IPs 2012-08-30 16:43:44 +02:00
Martin Willi 13f11ccf46 Don't parse comma separated pool names in attr-sql 
We now handle multiple pools at a deeper level, making that special
handling obsolete. Comma separated pools are parsed in stroke.

Martin Willi d8eec395b2 Add a getter for the mem_pool_t base address 2012-08-24 11:19:07 +02:00
Tobias Brunner 31a0e24b0f Increased log level when listing interfaces and IP addresses during startup 
This avoids confusing log messages in starter and ipsec statusall
already lists the available addresses anyway.

Tobias Brunner 3a917ac77f Validate netmask in mem_pool_create 2012-08-13 13:54:28 +02:00
Tobias Brunner 156f7e9b85 Moved types used by kernel_ipsec_t interface (and libipsec) to libstrongswan 
This avoids a dependency of libipsec to libhydra.

Tobias Brunner 63afd833b9 Avoid SIGSEGV during shutdown if charon is not started as root 2012-06-25 19:00:00 +02:00
Tobias Brunner 26d77eb3e6 Centralized thread cancellation in processor_t 
This ensures that no threads are active when plugins and the rest of the
daemon are unloaded.

callback_job_t was simplified a lot in the process as its main
functionality is now contained in processor_t.  The parent-child
relationships were abandoned as these were only needed to simplify job
cancellation.

Tobias Brunner 7beb31aae4 Fixed IPv6 source address lookup 
Because Linux kernels prior to 3.0 do not support RTA_PREFSRC for
IPv6 routes we didn't use NLM_F_DUMP to get all routes.
Still routes installed with policies are installed also for IPv6.
So since only one route is returned without DUMP, and we ignore
all routes from our own routing table, no source address was found
during roaming if DST of the installed route included the IKE peer.

With newer kernels we can now use DUMP as we did for IPv4 already,
for older kernels we do so if our own routes are installed in a
separate routing table, otherwise we still use GET.
