Add new vcl_error method and make variables available in it.
Fix a bug in "error" action, where the numeric argument would not get
interpreted correctly if it came from a variable like obj.status.
Forbid "error" action in vcl_deliver since vcl_error now goes to
vcl_deliver to send the error object.
Fix test v00001 to reflect this.
Move the obj->ws/http initialization to preallocation time to avoid
duplication.

Add a facility to constructing a synthetic object from VCL.
This is just the initial version and it doesn't quite work the way

A new VCL syntactic element have been introduced to do this: "the
long string". A long string is anything from {" to "}, newlines,
controlcharacters and all. (Normal "..." strings cannot contain
control characters.
Technical details:
Don't NULL terminate string sequences in VRT context, we may have
NULL cropping up as a legal value if a header is missing, add the
magic "vrt_magic_string_end" for terminating string contactenation.

ACL code rewrite:
Add IPv6 support (untested!)
Implement evil-acls
IPv6 support
------------
I have implemented IPv6 filtering support, but I have done so blindly
as I have no IPv6 networks to test with.
Please double check before relying on this to work, and please report
your findings back to us.
Syntax
------
The ACL rules still have the same syntax, but the sematics have
expanded to handle IPv6 also:
acl foo {
"foohost"; // Match, if the address is one of the
// ipv4 or ipv6 addresses of "foohost"
! "foohost"; // Fail, if...
"192.168.1.7" / 24; // Use mask for comparison: The '7' is
// ignored
// Implicit masks:
!"172.16"; // Fail 172.16.0.0 to 172.16.255.255
"10.0.0"; // Match 10.0.0.0 to 10.0.0.255
"www.freebsd.org" / 24; // This will give compile error, because
// the "www.freebsd.org" has both ipv4
// and ipv6 addresses, and using the same
// mask for both kinds do not make sense.
( ... ); // Ignore this rule if DNS lookup fails.
( ! "idiot.net" ); // If we can resolve "idiot.net", then
// return Failure to match, if we see them.
}
Please notice that DNS lookup happens *only* on VCL compilation, if a
DNS record changes you need to recompile (ie: vcl.load or vcl.inline)
your VCL code again, it is not enough to just switch vcl (vcl.use).
(This is the same as with backend DNS lookups)
Evil-acls
---------
Most firewall or ip-filtering facilities, compile the lists of
networks and masks to a table, and matches proceed sequentially
through that table until the table is exhausted or a match is found.
Since we compile our ACLs into C-code, we might as well implement the
"evil-acl" concept, and compile the rules directly into C-code instead.
An ACL like this:
acl foo {
"172.16";
!"172.16.17";
"172.16.17.18";
"172.16"/18;
}
Compiles to:
if (fam == 2) {
if (a[0] == 172) {
if (a[1] == 16) {
if (a[2] == 17) {
if (a[3] == 18) {
VRT_acl_log(sp, "MATCH bar " "172.16.17.18");
return (1);
}
VRT_acl_log(sp, "NEG_MATCH bar " "172.16.17");
return (0);
}
else if ((a[3] & 0xc0) == 0) {
VRT_acl_log(sp, "MATCH bar " "172.16" "/18" );
return (1);
}
VRT_acl_log(sp, "MATCH bar " "172.16");
return (1);
}
}
}
VRT_acl_log(sp, "NO_MATCH bar");
return (0);
As can be seen, for example the comparison with "172" is now shared
for all four rules in the ACL, instead of being carried out once for
each of the four rules.
In addition to this optimization, the C-compiler will of course use
its usual (and unusual) tricks to speed things up, quite likely inlining
the ACL code in the VCL functions where they are referenced.
It will also be noticed, that the compiler sorts the rules in "most
specific order".
This means that:
"172.16.17.18";
gets tested before
!"172.16.17";
even though it is listed later in the ACL.
Previously we tested the rules in the order given.

Drop pseudo-automatic support for multihomed backends and require
clear expression of intent in VCL.
We now fail backend hostnames that resolve to multiple IPv4 or multiple
IPv6 addresses, in other words, you cannot use "cnn.com" as a backend
hostname specification without the compiler yelling at you:
% ./varnishd -d -d -b cnn.com -a :8080
Backend host "cnn.com": resolves to multiple IPv4 addresses.
Only one address is allowed.
Please specify which exact address you want to use, we found these:
64.236.16.20
64.236.16.52
64.236.24.12
64.236.29.120
[...]
VCL compilation failed
However, you _can_ use a hostname that resolves to both an IPv4 and
an IPv6 address, and the new paramter "prefer_ipv6" will determine
which one we try first in such cases.
The other part of this change is that we now do the DNS lookup at
VCL compiletime, and only then.
If your backend's DNS record (or /etc/hosts entry) changes IP#, you
must reload your VCL code to notify varnish.
Finer technical points:
We build a bytestring representation of the sockaddr's in VCC and
include them in the concept of backend identity, for an existing
backend (+ connections) to be reused for a new VCL the backend must
now be defined exactly the same way AND have the same resolved
IPv4/IPv6 addresses.
Since we never muck about with the address in the backend struct
anymore, it's static for the life of the struct backend instance,
we can simplify and eliminate the locking dance around our connection
attempts.
Also eliminate the struct vrt_backend inclusion in struct backend,
and instead make the relevat fields full-blown members of struct
backend. This eliminates a number of TRUST_ME() calls.
This is the companion commit to #2934 which prepared the VCL compiler.
