This is a collection of issues which have shown up
since the version 0.8.8 was released. The issues are
ordered by numbers of ser versions to which they relate,
beginning with the newest release. Issues related to
operating systems are summarized in the bottom.
--------------------------------------------------------------
Desc: tls triggered crash on system with kerberos enabled openssl libs
Ser version: 0.10.x, 0.9.x
Reason: there is a bug in the openssl kerberos code (kssl.c):
libc malloc/free/calloc are used instead of the OPENSSL
versions. In ser ssl connections move between processes and
if normal mallocs are used (instead of ser shm versions) a
crash will occur eventually.
Quick openssl kerberos support check:
grep OPENSSL_NO_KRB5 openssl/opensslconf.h
If the above command returns no result => openssl is compiled with
kerberos support.
Workaround: use openssl versions not compiled with kerberos support or
try a late ser 0.10.x version compiled on the target machine
(its very important to compile against the same openssl library
as the one on the target machine)
CVS status: fixed / workarround enabled
--------------------------------------------------------------
Desc: ser crashes on startup if a group is specified (-g or group=)
Ser version: <=0.8.12
Reason: bad copy & paste :-)
Patch: http://www.mobile-ip.de/~andrei/ser/main_group.patch
Workaround: update from cvs or apply the corresponding patch
CVS status: fixed
--------------------------------------------------------------
Desc: textops search REs like "^From" fail to match on RH8
Ser version: all
Reason: there is a bug in RH8 libc, this kind of REs will never match
in case insensitive mode
Test: compile test/re_test.c (gcc re_test.c -o re_test) and try
echo -e "From:\nTo:" |./re_test -v '^From'
if your system is ok you should see 1 match, if not (and
your libc has this bug), 0 matches.
Workaround: ?upgrade?
--------------------------------------------------------------
Desc: textops REs match newline in constructs such [^@]
Ser version: all
Reason: there is a bug in newer linux libc versions (at least in
Debian libc6 2.3.x, Gentoo 1.4 lib 2.3.2, RH8, RH9, Fedora)
Test: compile test/re_test.c (gcc re_test.c -o re_test) and try
echo -e "From:\nTo:" |./re_test -v '[^.]+'
if your system is ok you should see 2 matches, if not (and
your libc has this bug), only 1 match.
Workaround: - use an older or fixed libc6 or avoid [^something]
- rewrite [^something] as [^something[:cntrl:]]
---------------------------------------------------------------
Desc: memory leaks occurs if SIP requests are processed in which
a Via header field occurs in end of header and includes
a parameter
Ser version: 0.8.10
Reason: parameter fragment is not linked to a list when EoH is
encountered
Patch: http://www.iptel.org/ser/issues/via_ml_0810.patch
CVS Status: fixed
---------------------------------------------------------------
Desc: ser segfaults on receipt of some messages (occurs
rather rarely with a very high number of messages,
typically during stress tests)
Ser version: 0.8.10 and before
Reason: valid TM label value 0 is considered mistakenly
a special value
Workaround: turn syn_branch config option off
Patch: http://www.iptel.org/ser/issues/hash_fix.patch
CVS Status: fixed
---------------------------------------------------------------
Desc: serctl returns "read: Illegal option -s" for "add user"
Ser version: 0.8.10 and before
Reason: serctl's use of some shell script commands not portable
Workaround: download serctl 1.45 and set SUBSCRIBER_COLUMN back
to user_id
Download: http://cvs.berlios.de/cgi-bin/viewcvs.cgi/*checkout*/ser/sip_router/scripts/sc?rev=1.45
CVS Status: fixed
---------------------------------------------------------------
Desc: 3261 ACKs for 200s are consumed by stateful processing
Ser version: 0.8.10
Reason: 200/ACKs which happen to have the same transaction ID
as original INVITE were not distinguished from hbh
ACKs and consequently absorbed
Patch: http://www.iptel.org/ser/issues/tid3261ack.patch
Workaround: apply the patch to 0.8.10 sources
CVS status: fixed
---------------------------------------------------------------
Desc: on sparc machines, usage of mysql library causes a bus error
Ser version: 0.8.10
Reason: ser is compiled with DBG_QM_MALLOC, which mistakenly uses
only alignment of four (ROUNDTO) -- insufficient for sparc
boxes, mysql library uses long long
Workaround: recompile with DBG_QM_MALLOC turned off or ROUNDTO redefined
to 8
CVS status: fixed
---------------------------------------------------------------
Desc: nonce validation doesn't work correctly on big endian machines.
BugId: 498
Ser version: 0.8.10
Patch: http://iptel.org/~janakj/nonce.c.patch
Workaround: Apply the patch to 0.8.10 sources
CVS status: fixed
---------------------------------------------------------------
Desc: ser 0.8.10 memory leak when an INVITE containing Route
header fields is received.
Symptoms: ser reports No memory left or crashes with BUG: qm_*: fragm.
BugId:n/a
Ser version: 0.8.10
Patch: http://iptel.org/~janakj/invroute.patch
Workaround: Apply the patch to 0.8.10 sources
CVS status: fixed
---------------------------------------------------------------
Desc: ser 0.8.10 fails to remove consumed verified credentials properly
and leaves characters in forwarded messages when consume_credentials
is used
BugId:n/a
Ser version: 0.8.10
Module: http://www.iptel.org/~jiri/ser/auth.tar.gz
Workaround: compile the auth module newly from sources above or
don't remove credentials (they only harm in terms of
packet size)
CVS status: fixed
---------------------------------------------------------------
Desc: ser 0.8.10 and earlier versions crash if contact list
excessively long
BugId: n/a
Ser version: 0.8.8, 0.8.9, 0.8.10
Patch: http://www.iptel.org/ser/security/secalert-002-0_8_10.patch
Workaround: apply the patch to 0.8.10 sources
CVS status: fixed
---------------------------------------------------------------
Desc: ser 0.8.10 won't compile with bison 1.75
BugId: n/a
Ser version: 0.8.8, 0.8.9, 0.8.10
Patch:
0.8.10 http://www.mobile-ip.de/~andrei/ser/0.8.10/ser-0.8.10-bison-1.75.patch
0.8.9 http://www.mobile-ip.de/~andrei/ser/0.8.9/ser-0.8.9-bison-1.75.patch
Workaround: update from cvs, apply the corresponding patch or downgrade bison
CVS status: fixed
---------------------------------------------------------------
=================================================================================
* ser 0.8.10 released, all the issues below this are fixed in ser 0.8.10, all the
* issues above are not :-)
=================================================================================
Desc: ser 0.8.9 won't log to stderr or syslog unless dontfork is set
(introduced when trying to fix bug 376)
BugId: n/a
Ser version: =0.8.9 (0.8.8 is ok)
Patch: http://www.mobile-ip.de/~andrei/ser/0.8.9/ser-0.8.9_log.patch
Workaround: update from cvs or apply the patch.
CVS status: fixed
---------------------------------------------------------------
Desc: local domain mismatch resulting in infinite loops
(With default configuration and domain names in a request
URI's, ser may not match "owned domain" in the
script's uri==myself condition, consider the request to
be for outside domain, and forward it to itself, resulting
in an infinite loop and "482" returned back to UAC.)
BugId: n/a
Reason: aliases do not support reverse DNS lookups yet
Workaround: Start ser with "alias=hostname" in config file
CVS status: fixed
---------------------------------------------------------------
Desc: sendto problems on FreeBSD
(when using tm sendto fails because of bad sockaddr len passed
to it)
BugId: n/a
Workaround: update from cvs or apply the following patch:
http://www.mobile-ip.de/~andrei/ser/0.8.9/update_sock_struct_from_ip.patch
CVS status: fixed
---------------------------------------------------------------
Desc: full ipv6 addresses (w/o ::) are converted to 0:0:0:0:0:0:0
(ser will listen on :: instead of the specified address)
BugId: n/a
Workaround: use ipv6 addresses w/ :: or compile ser without -DDNS_IP_HACK
(Makefile.defs).
CVS status: fixed
================================================================================
* ser 0.8.9 released, all the issues below this are fixed in ser 0.8.9, all the
* issues above are not :-)
================================================================================
Desc: in default configuration, SER prints '127.0.0.1' in
Warning header field of all replies
BugId: 372
Workaround: use listen=<ip_address> in your configuration file;
that will make SER listen only on one interface (and not
on '127.0.0.1' in parallel) and advertise correct IP
address
Bug reason: multiple listening address ignored in message
translator
CVS status: fixed
---------------------------------------------------------------
Desc: serctl add ... returns "user exists"
BugId: 374
Workaround: either use serweb for adding new users or update
the serctl utility from CVS; the fixed version is at
http://www.iptel.org/ser/issues/374/
Bug reason: phplib_id ignored in sc
CVS Status: fixed
---------------------------------------------------------------
Desc: SMS, MSILO & JABBER modules fail to load because of unresolved
dependency on im.so
BugId: 375
Workaround: change the makefiles & recompile
Bug reason: removal of RTLD_GLOBAL from dlopen.
CVS status: fixed
---------------------------------------------------------------
Desc: when forking & std_error=yes no open FD is closed
BugId: 376
CVS status: fixed
---------------------------------------------------------------
Desc: exec module missing in binary RPM distro
BugId: -
CVS status: fixed
Workaround: compile from source distribution
---------------------------------------------------------------
Desc: when debug=3 & iptel.cfg is used mysql module fails in submit_query.
Workaround: use debug=9 or use log_stderr
Reason: unknown
BugId: 377
Cvs status: not fixed
================================================================================
* OS-related issues
================================================================================
----------------------------------------------------------------
Desc: ser won't run on linux kernels <2.4 (fails with EINVAL when
initializing the shared memory)
BugId: n/a
Ser version: 0.8.8, 0.8.9, 0.8.10
Workaround: Upgrade to a 2.4.* kernel (older kernels don't support shared
mmaping of /dev/zero ) or recompile ser with SYSV shm instead of
mmap (remove -DSHM_MMAP from Makefile.defs)
CVS status: n/a
---------------------------------------------------------------
Desc: Solaris resolver memory leak
(getipnodebyname on Solaris has a memory leak. unpatched
solaris 8 installations will fail after processing
~ 360000 requests)
BugId: n/a
CVS status: n/a
Workaround: patch your Solaris OS
