server where the client is (or was) on. Just like we did in UnrealIRCd 5.
Not sure if API-wise and variable-name-wise I want to do it this way,
but whatever...
(the new fallback https-only implementation).
./configure will set URL= to either url_curl.o or url_unreal.o
depending on whether curl is enabled or not.
The 3 functions that both implementations had in common are now in
src/misc.c: url_is_valid(), displayurl() and url_getfilename().
have that in dns.c. Also remove verify_hostname() from dns.c and
integrate it in valid_host() which now takes a second argument
named 'strict'. Call valid_host() with strict set to 1 if the
hostname should be checked to be a valid DNS hostname, eg the
host may not contain stuff like ':' or '/'. Use 0 otherwise
for the loose check, eg if you are not sure if the passed host
is an IP address or a host, or if it is for a vhost.
IP address in the message. We now use ip:port from the link block
if we failed to connect, and otherwise we use the ip from the
connection if the connection is established (also because it
can be a remote connection, not linked directly to us)
just like client->user is set if the client is a user.
Rename client->srvptr to client->uplink: this is the uplink that the client
is connected to. If the client is a user then it is set to the server that
the client is connected to, if the client is a server then it is set to the
server that the server is connected to (the.. tadah.. uplink).
For local clients it is always set to &me.
We now also correctly disable color support if someone is on
a color-capable terminal but redirects the output of the boot
to a file, eg: bin/unrealircd >boot.log 2>&1
This means we now have $client.user.username but the expansion system
does not allow items more than 2 deep atm (only $client.something
but not $client.something.other). Will fix later. (TODO)
In the meantime the connection notice will look weird :D
Also rename them to describe better what they do.
ConfigFile:
cf_filename -> filename
cf_next -> next
cf_entries -> items
ConfigEntry:
ce_fileptr -> file
ce_varlinenum -> line_number
ce_fileposstart -> file_position_start
ce_fileposend -> file_position_end
ce_sectlinenum -> section_linenumber
ce_varname -> name
ce_vardata -> value
ce_cond -> conditional_config
ce_entries -> items
ce_next -> next
ce_prevlevel -> parent
Also add doxygen docs for both structs.
This adds __attribute__((format(printf,X,Y))) to several functions.
It also adds checking only for the non-literal case to some functions
such as unreal_log/unreal_do_log.
This so we can more easily detect format string issues. Especially now with
the recoding of the logger and with possible future mistakes in this area
in UnrealIRCd 6 itself or in third party modules.
The check is currently disabled in these files, which are TODO items:
* src/send.c: still much work to do
* src/socket.c: due to report_error and report_baderror().
I want to get rid of these functions and integrate them
in the new logger anyway.
* src/serv.c: only disable for hunt_server()
Broken now:
- All filtering (log::flags)
- Everything is seen as error unknown UNKNOWN
Working:
- log::type json
- logging still works, other than the limitations of above
- If you have only negating entries, like '!abc' and '!def', then
we assume an implicit * rule first, since that is clearly what
the user wants.
- If you have a mix, like '*.com', '!irc1*', '!irc2*', then the
implicit * is dropped and we assume you only want to match *.com,
with the exception of irc1*.com and irc2*.com.
- If you only have normal entries without ! then things are
as they always are.
This patch also makes the behavior for unreal_mask_match() and
unreal_mask_match_string() the same.
Reported by Ariadne Conill in https://bugs.unrealircd.org/view.php?id=5906
This patch applies cleanly against 5.2.0-rc1 and 5.0.9.x.
Needs more testing, though, as fiddling with SQUIT code and the
various directions and far/near server distinctions can be tricky.
The new target type is called 'T' and we match against "name=value"
of each message tag (or just "name" if it is without value).
Example: SPAMFILTER ADD -simple T kill 0 this_is_a_test +typing=active
(No this is not a suggestion :D)
This probably won't be used much at all, but it is good to have the
option available in case there is some massive problem,
especially since more message tags may pop up sooner or later.
Caveat: this is actually a bit slow as we may have to check multiple
message tags for a single line.
If there are zero message-tag spamfilters then we will automatically
short-circuit and save all this CPU, which will be the most common case.
