null_encrypt() needs to copy the data in case src and dst are disjunct, null_compress() needs to copy the data in any case as far as I can tell. I joined compress/decompress and encrypt/decrypt to avoid duplicating code. Without this patch ESP null_enc packets look like this: IP (tos 0x0, ttl 64, id 23130, offset 0, flags [DF], length: 128) 10.0.0.1 > 10.0.0.2: ESP(spi=0x0f9ca149,seq=0x4) 0x0000: 4500 0080 5a5a 4000 4032 cbef 0a00 0001 E...ZZ@.@2...... 0x0010: 0a00 0002 0f9c a149 0000 0004 0000 0000 .......I........ 0x0020: 0000 0000 0000 0000 0000 0000 0000 0000 ................ 0x0030: 0000 0000 0000 0000 0000 0000 0000 0000 ................ 0x0040: 0000 0000 0000 0000 0000 0000 0000 0000 ................ 0x0050: 0000 ..
