Hi,
I found a funny bug, when made some tests. I found out that if you try to give bird a full-length IPv6-address, like: ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff 1111:2222:3333:4444:5555:6666:7777:8888 You will get an error: "syntax error, unexpected BYTESTRING".
Hi
Thanks for remainding me about that issue. I noticed that some time ago, fixed it in one of my private branches and then completely forgot about that. Will merge it.
I find it happens in conf/cf-lex.l because of how BYTESTRING is defined before IP6, it is too liberal to the forms of bytestrings, allowing almost arbitrary mix of ':' and digits. I suspect the idea was it allow 32-digit strings without delimters or with groups of 2 digits delimited by ':'. See proposed changes in the patch. By the way, that possibility for string literals is not documented. :)
The idea is 32-digit or more. Also, it is not generic string literals,
Ok, then my patch is not fully correct, but you know what to do anyway. :) it is limited to cryptographic keys, and documented:
You are right. Sorry, my bad, missed that part.
A password can also be specified as a hexadecimal key. <m/hex_key/ is a sequence of hexadecimal digit pairs, optionally colon-separated. A key specified this way must be at least 16 bytes (32 digits) long (although specific algorithms can impose other restrictions).
