Bram Matthys e2158e3608 Fix possible lack of string termination (NUL) in buildvarstring() 2019-10-17 21:01:55 +02:00
Bram Matthys cc36b34f93 Remove unnecessary (void) casts everywhere.
Only use (void) for system/library calls that you want to ignore
explicitly, eg (void)close, if the return value is irrelevant.

Bram Matthys 394168c288 Style fixes: "char* " -> "char *" etc. 2019-10-11 12:23:45 +02:00
Bram Matthys 1d0fa3278f Protect against flawed S2S traffic: more checks for bad base64
encoded IP addresses.

Bram Matthys de87b439b7 Update memory allocation routines. Step 1 of X. 2019-09-14 16:52:53 +02:00
Bram Matthys 7c6358024c Add 'natural order' string comparison to core: strnatcmp and strnatcasecmp
extern int strnatcmp(char const *a, char const *b);
extern int strnatcasecmp(char const *a, char const *b);
This will be handy for version comparisons. For example they will
return -1 (=lower) for things like ("1.4.9", "1.4.10"), unlike strcmp.

Also, some loosely related spelling fixes elsewhere.

Bram Matthys ec2fdb82e0 Get rid of configure check for strerror() 2019-09-09 17:45:24 +02:00
Bram Matthys 80bc15c6d3 Apparently our strtoken() is special, don't bother then. Still, get rid of
the configure check.
2019-09-09 17:32:59 +02:00
Bram Matthys 1cdbbe043f Make strtoken() use strtok_r / strtok_s.
And get rid of the config check, as strtoken() never existed anyway.

Bram Matthys 078cfa88ea Get rid of configure check for strtok()
[skip ci]
2019-09-09 16:58:44 +02:00
Bram Matthys 36cb2226cc Get rid of checking inet_pton/net_ntop. Should be available on IPv6-capable
operating systems. And we require IPv6-capable since UnrealIRCd 4 already,
so.. ;)
2019-09-09 16:51:31 +02:00
Bram Matthys 8d453ffc40 Get rid of index() and some useless casts 2019-09-09 14:54:49 +02:00
Bram Matthys d434cf948b Get rid of bcmp/bcopy/bzero. 2019-09-09 14:41:40 +02:00
Bram Matthys 6ead10f42d Windows: build with /WX (equivalent to -Werror) and turn on
/analyze again. Not sure how long I can bear that last one though
as now compilation takes about 15 minutes rather than a few.
2019-08-25 14:03:11 +02:00
Bram Matthys 8484511296 Make Windows build compile without warnings with /W3
Disable these warnings, though:
C4267: downgrade of size_t to int and such. pointless...
C4101: unreferenced local variable
C4018: signed/unsigned mismatch
C4244: implicit conversions with "possible loss of data".
       there are 75+ of them and they are likely all harmless
       and/or intentional (usually plain obvious too)
C4996: fixme! warnings about deprecated functions, currently only for GetVersion..
2019-08-25 13:00:31 +02:00
Bram Matthys d357ef8957 More config.h cleanups. Lower kill chase time limit from 90 to 30
which seems more reasonable to me.
2019-08-24 19:57:40 +02:00
Bram Matthys d8f080de67 Drop support for systems without snprintf() and vsnprintf()
Those are in POSIX.1-2001. Even Windows has them nowadays...
"Our" implementation doesn't even work properly under Win64.
2019-08-22 16:41:39 +02:00
Bram Matthys ded4a65a60 u_int16_t -> uint16_t and u_int32_t -> uint32_t, remove typedefs for
these types and others, that should no longer be needed thanks to
stdint.h.
2019-06-26 17:06:46 +02:00
Bram Matthys 7161f33311 Code cleanup: make src/*.c use the generic #include "unrealircd.h" file
(with only a few exceptions)
Now, we'll find out later if Windows still compiles, I guess ;)
2019-06-22 21:18:08 +02:00
Bram Matthys f9b589d0c6 Remove almost 1000 lines, all functions that are (now) unused.
Also, drop support for snomasks to non-ircops (TODO: more)
2019-06-22 19:32:11 +02:00
Bram Matthys 7542cdeaca Cleanup of m_tkl part 1. New tkl_chartotype (the reverse of tkl_typetochar).
Move stripcrlf() to core instead of at 3 places, rename calls of iCstrip()
to that. Hopefully I didn't break anything.. :D
2019-06-15 16:56:34 +02:00
Bram Matthys 67d691fce9 * New set::outdated-tls-policy which describes what to do with clients
that use outdated SSL/TLS protocols (eg: TLSv1.0) and ciphers.
  The default settings are to warn in all cases: users connecting,
  opers /OPER'ing up and servers linking in. The user will see a message
  telling them to upgrade their IRC client.
  This should help with migrating such users since in the future, say one
  or two years from now, we would want to change the default to only allow
  TSLv1.2+ with ciphers that provide Forward Secrecy. Instead of rejecting
  clients without any error message, this provides a way to warn them and
  give them some time to upgrade their outdated IRC client.

Bram Matthys bb4758f321 Add strldup() and safestrldup(), reducing ridiculous amount of code in
m_pass and m_topic.c when duplicating strings with a length limit.
+/* strldup(str,max) copies a string and ensures the new buffer
+ * is at most 'max' size, including nul byte. The syntax is pretty
+ * much identical to strlcpy() except that the buffer is newly
+ * allocated.
+ * If you wonder why not use strndup() instead?
+ * I feel that mixing code with strlcpy() and strndup() would be
+ * rather confusing since strlcpy() assumes buffer size including
+ * the nul byte and strndup() assumes without the nul byte and
+ * will write one character extra. Hence this strldup(). -- Syzop

Bram Matthys d5d446c38d More code cleanups to get rid of useless casts and other useless
structures such as:
-       lp->value.cp = (char *)MyMalloc(strlen(mask) + 1);
-       (void)strcpy(lp->value.cp, mask);
+       lp->value.cp = strdup(mask);

Bram Matthys 658cbf04da Compile fixes for Ubuntu 16 LTS (gcc 5.4.x?) 2016-12-14 18:42:12 +01:00
Bram Matthys 7aaf14c138 Show PCRE2 version on ./unrealircd start and in /VERSION on IRC if oper. 2016-09-30 15:42:19 +02:00
Bram Matthys 64b5d89a98 Remove support for CHROOTDIR, IRC_USER and IRC_GROUP as these caused too much
code clutter and was broken anyway (especially CHROOTDIR)...
For a CHROOTDIR replacement we suggest using AppArmor, SELinux, FreeBSD jails, ..
For a IRC_USER/IRC_GROUP replacement you can use start-stop-daemon or similar.

Bram Matthys 820344f49f Fix crash on Windows upon bind error (eg: incorrect link::outgoing::bind-ip) 2016-04-04 13:23:15 +02:00
Bram Matthys 34b9797ffc Add buildvarstring() function and make blacklist module support %ip and %server variables in reason field. Suggested by blank (#4507). 2015-12-28 19:03:05 +01:00

Bram Matthys ea7a080154 remove more unused functions 2015-07-28 21:44:32 +02:00
Bram Matthys 58b864edd5 Re-do CIDR and at the same time all the user matching stuff. Introducing match_user(mask, acptr, options): this should be used everywhere rather than the many DIY routines everywhere that create a nick!user@host and then run a match() on it.
The match_user() function is not been fully tested yet, at this point I'm happy we can compile again.

Bram Matthys c06dc9a142 Get rid of #ifdef CLEAN_COMPILE, along with some other shit 2015-07-16 17:22:51 +02:00
Bram Matthys dd3993008c small unlikely memleaks. and cptr->port being set to a random value (caused few weeks ago).. but we don't ever read it so not terribly important. 2015-07-16 17:13:57 +02:00

William Pitcock ff2b229663 - fix type-punning in decode_ip(). (#4205) 2013-05-24 23:21:17 +00:00
William Pitcock afdf5d780a - Replace ircsprintf() with bounds-checking ircsnprintf(), patch from FalconKirtaran. (#4208) 2013-05-21 06:26:52 +00:00
William Pitcock 6085877aa7 - Remove TS2ts() and %B usage in formatter strings. Patch from FalconKirtaran (#4197, #4198). 2013-05-19 08:36:49 +00:00

by maxarturo (#4102).

binki 94c2b58366 - Fix a few compiler warnings with some double-casting and another const. (#3939) 2010-08-03 23:57:44 +00:00
binki 9faa5a6d2b - Fix files::shortmotd to by accepted by unrealircd like the docs say it is.
- Fix remote includes download handling which I broke for remote includes ;-).
- Recursively add more consts.
2010-06-17 02:41:43 +00:00
binki 06e807130c - Added error message for unknown directives in the "files" block
- Remote MOTD support. Not adequately tested. Required restructuring of the asynchronous download callback and handler.
- Added some consts throughout url.c, etc.
- Fix segfault where the an include directive specifies a URL and cURL follows redirects, resulting in a different resultant URL. The remote includes code would look for the an include block using the resultant URL and assume that it would be found. The new code searches differently, has new checks, and ignores the resultant URL.
- Removed duplicated m_motd() and friends that were both in modules and s_serv.c. The copies in s_serv.c (core) were overriding the in-module functions.
2010-06-16 05:44:15 +00:00
