+ *
+ * This source code is licensed under General Public License version 2.
+ *
+ *
+ * This library is based on H.225 version 4, H.235 version 2 and H.245
+ * version 7. It is extremely optimized to decode only the absolutely
+ * necessary objects in a signal for Linux kernel NAT module use, so don't
+ * expect it to be a full ASN.1 library.
+ *
+ * Features:
+ *
+ * 1. Small. The total size of code plus data is less than 20 KB (IA32).
+ * 2. Fast. Decoding Netmeeting's Setup signal 1 million times on a PIII 866
+ *    takes only 3.9 seconds.
+ * 3. No memory allocation. It uses a static object. No need to initialize or
+ *    cleanup.
+ * 4. Thread safe.
+ * 5. Support embedded architectures that has no misaligned memory access
+ *    support.
+ *
+ * Limitations:
+ *
+ * 1. At most 30 faststart entries. Actually this is limited by ethernet's MTU.
+ *    If a Setup signal contains more than 30 faststart, the packet size will
+ *    very likely exceed the MTU size, then the TPKT will be fragmented. I
+ *    don't know how to handle this in a Netfilter module. Anybody can help?
+ *    Although I think 30 is enough for most of the cases.
+ * 2. IPv4 addresses only.

- * ip_conntrack_helper_h323_asn1.h - BER and PER decoding library for H.323
- *                                  conntrack/NAT module.
- *
- * Copyright (c) 2006 by Jing Min Zhao <zhaojingmin@users.sourceforge.net>
- *
- * This source code is licensed under General Public License version 2.
- *
- *
- * This library is based on H.225 version 4, H.235 version 2 and H.245
- * version 7. It is extremely optimized to decode only the absolutely
- * necessary objects in a signal for Linux kernel NAT module use, so don't
- * expect it to be a full ASN.1 library.
- *
- * Features:
- *
- * 1. Small. The total size of code plus data is less than 20 KB (IA32).
- * 2. Fast. Decoding Netmeeting's Setup signal 1 million times on a PIII 866
- *    takes only 3.9 seconds.
- * 3. No memory allocation. It uses a static object. No need to initialize or
- *    cleanup.
- * 4. Thread safe.
- * 5. Support embedded architectures that has no misaligned memory access
- *    support.
- *
- * Limitations:
- *
- * 1. At most 30 faststart entries. Actually this is limited by ethernet's MTU.
- *    If a Setup signal contains more than 30 faststart, the packet size will
- *    very likely exceed the MTU size, then the TPKT will be fragmented. I
- *    don't know how to handle this in a Netfilter module. Anybody can help?
- *    Although I think 30 is enough for most of the cases.
- * 2. IPv4 addresses only.
