Tobias Brunner b6a071514a Fixed ip_packet_t if IPv6 is not available 2012-08-08 15:41:03 +02:00
Tobias Brunner 34400edc37 Added utility class to create TUN devices 
Currently works only on Linux.
 2012-08-08 15:41:03 +02:00
Tobias Brunner a113d7f29b Added IPsec processor which is responsible for handling in- and outbound packets 
Two callbacks can be registered that get called when new inbound plaintext and
outbound ESP packets have been processed. Inbound ESP and outbound plaintext
packets can be queued for processing with two other methods.
 2012-08-08 15:41:03 +02:00
Tobias Brunner b37758c41e Represent the payload of an ESP packet as ip_packet_t instead of a chunk_t 2012-08-08 15:41:03 +02:00
Tobias Brunner 2e1a19136d IPsec policies can be looked up based on an IP packet 2012-08-08 15:41:03 +02:00
Tobias Brunner 2dd47c2442 ip_packet_t parses the header of IP packets 2012-08-08 15:41:03 +02:00
Tobias Brunner ed1f0c234f Order IPsec policies by a pseudo-priority based on the traffic selectors 
This allows a simple lookup, i.e. just use the first policy that matches
a given IP packet.
 2012-08-08 15:41:03 +02:00
Tobias Brunner f1b4238311 Implemented a checkout/checkin mechanism for IPsec SAs 
SAs can only be checked out by a single thread and all other threads
block until the SA is checked in again.
 2012-08-08 15:41:03 +02:00
Tobias Brunner 7000cf11b1 IPsec policy manager added 
This version only provides the very simplest management functions.
 2012-08-08 15:41:03 +02:00
Tobias Brunner 3b8276b405 Method added to easily compare IPsec policies 2012-08-08 15:41:03 +02:00

Tobias Brunner e6cfd527df Schedule and relay expiration events for created IPsec SAs 2012-08-08 15:41:03 +02:00
Tobias Brunner b50f56f326 Added class to relay IPsec events (like expiration) to listeners 
Currently, only expiration of IPsec SAs is supported.  Later other events
for e.g. acquires or changed NAT endpoints could be added.
 2012-08-08 15:41:03 +02:00
Tobias Brunner 914479370e Added IPsec SA manager 2012-08-08 15:41:03 +02:00

Tobias Brunner f9b0c05475 Class representing an IPsec SA added 
The IPsec SA also manages the respective ESP context.
 2012-08-08 15:41:02 +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.
 2012-08-08 15:41:02 +02:00
Tobias Brunner 053276e69a Use a CALLBACK feature to create charon's sender and receiver 2012-08-08 15:41:02 +02:00
Tobias Brunner 2dde79aca6 Added a simple blocking queue around linked_list_t 2012-08-08 15:41:02 +02:00
Tobias Brunner 05a2a7950c esp_packet_t implements packet_t interface 
This should allow to avoid unnecessary cloning of packet data.
 2012-08-08 15:41:02 +02:00
Tobias Brunner ec486e9433 Extended constructor for packet_t added (takes src, dst and data) 2012-08-08 15:41:02 +02:00
Tobias Brunner 5764a9b355 Moved packet_t to libstrongswan 2012-08-08 15:41:02 +02:00
Tobias Brunner 3320b87a62 Headers from libhydra (kernel interface related) are required in libipsec 2012-08-08 15:41:02 +02:00
Tobias Brunner 47eb8943b2 ESP packet wrapper added, handles encryption/decryption/verification etc. 2012-08-08 15:41:02 +02:00
Tobias Brunner 64004973e3 Adding class to manage ESP context (crypto, sequence numbers) 2012-08-08 15:41:02 +02:00
Tobias Brunner 6dfdcf420f Added a method to bio_writer_t that allows to skip a number of bytes 
A chunk pointing to the skipped bytes is returned, allowing users of
bio_writer_t to write/copy data to the skipped bytes themselves.
 2012-08-08 15:41:02 +02:00
Tobias Brunner 59a15a7475 Added a method to bio_writer_t that allows to extract the internal buffer 2012-08-08 15:41:02 +02:00
Tobias Brunner c1830d2670 Added methods to bio_reader_t to read data from end of buffer 2012-08-08 15:41:02 +02:00
Tobias Brunner f3fefb1847 Increase log verbosity when sending NAT keep-alives 2012-08-08 15:41:02 +02:00
Tobias Brunner 6d11dd5770 Only log the sending of regular packets in sender_t 
When sender_t is used to send ESP packets this would otherwise cause an extreme
amount of debug messages.
With this change all messages sent via sender_t.send_no_marker() cause no extra
DBG1 log message, but for debugging purposes the socket plugins do log the same
message again with DBG2 for all packets.
 2012-08-08 15:41:02 +02:00
Tobias Brunner 6fbf4472ea Added option to prevent socket-default from setting the source address on outbound packets 2012-08-08 15:39:07 +02:00
Tobias Brunner 95dacbbc70 Allocate UDP ports randomly in Android NDK build. 2012-08-08 15:30:28 +02:00
Tobias Brunner 224ab4c59b socket-default plugin allocates random ports if configured to 0. 
Also added strongswan.conf options to change the ports.
 2012-08-08 15:30:27 +02:00
Tobias Brunner b223d517c8 Replaced usages of CHARON_*_PORT with calls to get_port(). 2012-08-08 15:12:25 +02:00
Tobias Brunner a7babe25ee Added get_port() method to socket_t to learn the listening port. 2012-08-08 15:12:25 +02:00
Tobias Brunner 56d07af3be Added ESP log group for libipsec log messages. 2012-08-08 15:12:25 +02:00
Tobias Brunner 75f8316332 Use send_no_marker to send NAT keepalives. 2012-08-08 15:12:25 +02:00

Tobias Brunner 73470cfe57 Added packet_t.skip_bytes method to skip bytes at the start of a packet. 2012-08-08 15:12:25 +02:00
Tobias Brunner 896941d365 Improved how NAT-T keepalives are handled in sockets/receiver. 2012-08-08 15:12:24 +02:00
Tobias Brunner e49abcede0 Let kernel interfaces decide how to enable UDP decapsulation of ESP packets. 2012-08-08 15:12:24 +02:00
Tobias Brunner 08b2ce7aa7 Callback for ESP packets added to receiver. 2012-08-08 15:12:24 +02:00
Tobias Brunner 064da8b96b Add Non-ESP marker in sender and not individual socket plugins. 2012-08-08 15:12:24 +02:00
Tobias Brunner 65da43e2fc Handle Non-ESP marker in receiver and not individual socket plugins. 2012-08-08 15:12:24 +02:00
Tobias Brunner a405760395 Java code style fixed (analogous to C code). 2012-08-08 15:12:24 +02:00
Tobias Brunner 06ed785e5a Load libipsec in Android app. 2012-08-08 15:12:24 +02:00
Tobias Brunner b70139fbfd Stub library for user space IPsec implementation added. 2012-08-08 15:09:31 +02:00
Tobias Brunner 48f2c4b69b Some NDK build info updated. 2012-08-08 15:09:31 +02:00
Tobias Brunner 9ddc7cbfff Changed minimal SDK/API level to 14. 2012-08-08 15:09:31 +02:00
Tobias Brunner 4a20814300 Added android.net.VpnService wrapper around charon (loaded via JNI). 2012-08-08 15:09:31 +02:00
Tobias Brunner da848ab894 Added Android shell app created with Android SDK. 2012-08-08 15:09:30 +02:00
Tobias Brunner 2f203aee0e Android.mk for NDK build added. 2012-08-08 15:09:30 +02:00
Tobias Brunner 3fa8d7738e Extracted some parts from Android.mk.in which can be used for NDK builds. 2012-08-08 15:07:43 +02:00
Tobias Brunner 80b267f9e3 Use filter instead of findstring to check for enabled plugins in Android.mk. 
findstring is not prefix-safe (i.e. android matches android-log). On
the other hand filter matches words separated by whitespace and if no
wildcard (%) is used the full word has to match.
 2012-08-08 15:07:43 +02:00
Tobias Brunner 162621ed57 Moved Android specific logger to separate plugin. 
This is mainly because the other parts of the existing android plugin
can not be built in the NDK (access to keystore and system properties are
not part of the stable NDK libraries).
 2012-08-08 15:07:43 +02:00
Tobias Brunner 657a3ba609 Link android plugin against liblog in the NDK. 
Doesn't seem to hurt the build within the source tree.
 2012-08-08 15:07:43 +02:00
Tobias Brunner e7ea057fd2 Make the UDP ports charon listens for packets on (and uses as source ports) configurable. 2012-08-08 15:07:43 +02:00
Tobias Brunner 73940eb712 Make path to Android OpenSSL headers configurable. 2012-08-08 15:07:43 +02:00
Tobias Brunner 4528e74a5c Don't require STRONGSWAN_CONF to be defined. 2012-08-08 15:07:42 +02:00
Tobias Brunner a9f169f699 Don't require PLUGINDIR to be defined. 
If it is not available, we just load monolithically built plugins.
 2012-08-08 15:07:42 +02:00
Tobias Brunner 6204c1182d Include src address in hash of initial message for Main Mode 
If two initiators use the same SPI and also use the same SA proposal the
hash for the initial message would be exactly the same.  For IKEv2 and
Aggressive Mode that's not a problem as these messages include random
data (Ni, KEi payloads).
 2012-08-08 14:47:36 +02:00
Tobias Brunner decc467a4f Implemented recursive mutex without thread-specific counter 2012-08-03 11:30:18 +02:00
Tobias Brunner 920f29e7d5 Use a single thread-specific value for our custom rwlock_t implementation 
The pthread implementation on Android currently only supports 64
different thread-specific values per process, which we hit easily when
every rwlock_t requires one.
 2012-08-03 11:30:18 +02:00
Tobias Brunner 63ac6d00b0 Proper fallback if capability dropping is not available 2012-07-27 14:46:42 +02:00
Tobias Brunner 8ff1094823 The use of $< in Makefiles is not portable 
It requires GNU make which is not what most people use on e.g. FreeBSD.

Fixes #205.
 2012-07-27 13:47:59 +02:00
Tobias Brunner d511a71daa Include stdint.h for UINTxx_MAX defines 
Fixes #205.
