When the write buffer space grows too large, ngircd has to disconnect
the client to avoid wasting too much memory.
ngircd logs this with a scary 'write buffer overflow' message.
Change this to a more descriptive wording.
Not all servers (and services!) using the RFC1459 protocol style send
prefixes on all commands; so don't require them to do so.
This relaxes the requirements introduced by commit 15775e679.
We re-use the same helper function for both forward lookups
(when we want to connect to a peer server) and for validation of reverse
loopups (where we make a lookup on the hostname returned
by a reverse lookup on the IP address that connected).
Problem:
When ConnectIPv6=no, the forward lookup helper sets the adderss family
to AF_INET, and, if out client connected via ipv6, we fail to validate
the result.
Thus move the ConnectIPvX check out of the helper.
we do not need this for cryptographic purposes, but we can do better
than plain srandom(getpid()).
Also, keep in mind that rng state is inherited across fork(), so re-init
it in the child.
When enabled, this configuration option lets ngIRCd send a PING with an
numeric "token" to clients logging in; and it will not become registered
in the network until the client responds with the correct PONG.
This is used by QuakeNet for example (ircu/snircd), and looks like this:
NICK nick
:irc.example.net PING :1858979527
USER user . . :real name
PONG 1858979527
:irc.example.net 001 nick :Welcome to the Internet Relay Network ...
Make sure that all commands received from other servers do have
valid prefixes.
Only exceptions are PING and ERROR commands that can occure without
prefixes when generated by the remote peer itself.
* CloakUserHost:
Add a note not to use a percent sign ("%") in CloakHost variable
Rename ClientHost to CloakHost, and ClientUserNick to CloakUserToNick
Don't use "the.net" in sample-ngircd.conf, use "example.net"
ngircd.conf.5: document "ClientHost" and "ClientUserNick"
Move "ClientHost" and "ClientUserNick" to end of [Global] section
ClientUserNick setting
ClientHost setting
* QuitOnHTTP:
Only "handle" HTTP commands on unregistered connections
Don't use IRC_QUIT_HTTP() if STRICT_RFC is #define'd
IRC_QUIT_HTTP(): enhance error message
Move IRC_QUIT_HTTP() below IRC_QUIT()
quit on HTTP commands: GET & POST
* bug72-WHOIS-List:
Add "whois-test" to testsuite and distribution archive
Add support for up to 3 targets in WHOIS queries.
also allow up to one wildcard query from local hosts.
Follows ircd 2.10 implementation rather than RFC 2812.
At most 10 entries are returned per wildcard expansion.
WHOIS test cases by Dana Dahlstrom.
previously, any client could join in this configuration:
[Channel]
Name = #test
Modes = tnk
KeyFile = /tmp/foobar
fix this by checking for zero-length key before comparing
key to channel key.
This fixes the followin GCC warning on modern Linux systems as well:
irc-login.c: In function ‘Hello_User’:
irc-login.c:876: warning: ignoring return value of ‘write’,
declared with attribute warn_unused_result
This patch
- makes the server write buffer bigger: 64k,
- makes the regular write buffer bigger: 32k,
- tries to flush the write buffer starting at 4K.
Before this patch, a client got disconnected if the buffer flushing at 4k
failed, now regular clients can store up to 32k and servers up 64k even
if flushing is not possible at the moment (e.g. on slow links).
Don't do a NULL-pointer dereference when a remote server using the
IRC+ protocol sends an invalid PASS command without the required
<serverversion> parameter ...
