3.7beta2 packages for openSUSE / SLES

Hi,

My unofficial syslog-ng 3.7 beta2 packages for openSUSE / SLES are now available, at this time completely untested (I'm sitting at a conference right now... :-) ). They are available at the usual location:

https://build.opensuse.org/package/show/home:czanik:syslog-ng37/syslog-ng

Python support failed to build on SLES11 (most likely missing pkg-config information for python) and java failed in post build checks...

Have a nice weekend!

Bye,

syslog-ng 3.7.0beta2

3.7.0beta2

This is the second beta release of the upcoming syslog-ng OSE 3.7
branch.

Changes compared to the previous alpha release:

Features

  • Added a geoip parser.

  • ssl_options inside tls() extended with the following set:
    no-sslv2, no-sslv3, no-tlsv1, no-tlsv11, no-tlsv12

  • minimal libriemann-client version bumped from 1.0.0 to 1.6.0

  • TLS support added to Riemann destination

  • timeout() option added to Riemann destination

Fixes

  • SyslogNg.jar removed from the release tarball.

  • When the configured host was not available during the initialization of
    afsocket destination syslog-ng just didn't start. From now, syslog-ng
    starts in that case and will retry connecting to the host periodically.

  • When a not writeable file becomes writeable later, syslog-ng recognize it
    (with the help of reopen-timer) and delivers messages to the file without
    dropping those which were received during the file was not available.

  • Fixed a configure error around libsystemd-journal.

  • --disable-python option and other Python related fixes addded to 
    configure

  • Retries fixed in SQL destination. In some circumstances when
    retry_sql_inserts was set to 1, after an insertion failure all incoming
    messages were dropped.

  • Added DOS/Windows line ending support in config.

  • Parallel build is supported for Python and Java destination drivers.

  • Fixed compilation failure on OpenBSD

  • Memory leak around reload and internal queueing mechanism has been fixed.

  • AMQP connection process fixed.

  • Fixed a potential abort when the localhost name cannot be detected.

  • Security issue fixed around $HOST.
    Tech details:
    When the name of the host is too long, the buffer we use to format the
    chained hostname is truncated. However snprintf() returns the length the
    result would be if no truncation happened, thus we will read uninitialized
    bytes off the stack when we use that pointer to set $HOST
    with log_msg_set_value().

    There can be some security implications, like reading values from the stack
    that can help to craft further exploits, especially in the presense of
    address space randomization. It can also cause a DoS if the hostname length
    is soo large that we would read over the top-of-the-stack, which is probably
    not mmapped causing a SIGSEGV.

  • Journal entries containing name-value pairs without '=' caused syslog-ng
    to crash. Instead of crashing, syslog-ng just drop these nv pairs.

Migrating from syslog-ng v 3.2.5 to 3.6.4

All;

    I am currently migrating a CentOS 6.6 server running syslog-ng 3.2.5 to a CentOS 7.1 system running syslog-ng 3.6.4. I’m trying to use the same configuration file, but I’m getting the following message:

 

/usr/sbin/syslog-ng -v -s -f /etc/syslog-ng/syslog-ng.conf

[2015-06-25T09:05:16.796854] Using /dev/log Unix socket with systemd is not possible. Changing to systemd-syslog source, which supports socket activation.;

 

 

I know one problem is that I’m just not up to speed yet with systemd, but I was hoping that someone could shed some light on this error. Any help at all would be greatly appreciated.

Thanks;

John V.

CentOS7 syslog-ng 3.5.6: TLS: SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca

Dear all,

I've this source settings for TLS:

source s_tcp_tls {
   network(  transport("tls")
             ip(10.46.130.65) port(6514)
             tls(
                   peer-verify("optional-untrusted")
                   key-file("/etc/syslog-ng/key.d/syslog-ng.key")
                   cert-file("/etc/syslog-ng/cert.d/syslog-ng.cert")
             )
   );
};

But when a client connects via TCP/TLS to the syslog-ng service..

In syslog-ng these messages are showing up:

syslog-ng starting up; version='3.5.6'
Syslog connection accepted; fd='12', client='AF_INET(10.46.160.78:48075)', local='AF_INET(10.46.130.65:6514)'
SSL error while reading stream; tls_error='SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca'
I/O error occurred while reading; fd='12', error='Connection reset by peer (104)'
Syslog connection closed; fd='12', client='AF_INET(10.46.160.78:48075)', local='AF_INET(10.46.130.65:6514)'
Closing log transport fd; fd='12'

I don't know why syslog-ng is proving the CA?
As far as I know the configuration is a non-mutual authentication - so the CA shouldn't play a role in this - is
this correct?

The client sends messages in RFC5424 format.

Any help is appriciated - I've no clue what's going wrong.

Best regards
  Klaus

mark-freq() and mark-mode() understanding

Hello.

I need an explanation of  mark-freq() and mark-mode() works.

=== a part of syslog-ng.conf ===
options {
	...
	mark-freq(300);
	...
	}

destination mesg	{ file("/var/log/syslog/messages" mark-mode(periodical)); };
===

=== a part of /var/log/syslog/messages ===
Jun 24 08:26:35 -- MARK --
Jun 24 08:30:01 crond[10512]: (root) CMD (   /usr/bin/freshclam --quiet --daemon-notify)
Jun 24 08:31:30 -- MARK --
Jun 24 09:01:01 crond[10544]: (root) CMD (run-parts /etc/cron.hourly)
Jun 24 09:25:30 syslog-ng[9983]: Log statistics ...
===

"MARK" label absent between 08:31:30 and 09:01:01 for example.
Does it turns out that "idle" is checked for all file() globally ?
Can I setup it for one file() ?

Cottington-Bray, Ian | 23 Jun 12:27 2015

Problems trying to compile syslog-ng 3.6.4 on Solaris 11.2 (SPARC)

Have compiled and installed eventlog-0.2.12  (into /usr/local/syslog-ng).

 

Now trying to compile syslog-ng I’m hitting the error shown at the end.

 

Following commands were used to configure the environment for the compile

 

export PKG_CONFIG_PATH=/usr/local/syslog-ng/lib/pkgconfig

./configure --prefix=/usr/local/syslog-ng --enable-sun-streams --enable-tcp-wrapper --enable-ipv6 --enable-sql --enable-ssh --with-ld-library-path=/usr/local/syslog-ng/lib --disable-amqp --enable-sun-door

 

Any suggestions ?

 

Thanks


Ian

CzP in Boston <at> Red Hat Summit

Hi,

This week I'm in Boston at the Red Hat Summit:
https://czanik.blogs.balabit.com/2015/06/red-hat-summit-syslog-ng-docker-containers/
If you are at the Summit or just in the Boston area and would like to
talk to a BalaBit engineer about syslog-ng, contact me by e-mail or
twitter ( <at> PCzanik)!

my unofficial 3.6.4 packages for opensuse/sles/fedora/rhel7

Hi,

Most of my unofficial syslog-ng packages are now ready:

openSUSE/SLES: https://build.opensuse.org/project/show/home:czanik:syslog-ng36

Fedora/RHEL7: https://copr.fedoraproject.org/coprs/czanik/syslog-ng36/

RHEL6 and FreeBSD ports will hopefully follow later this week. As I'm
off to the Red Hat Summit this week (
https://czanik.blogs.balabit.com/2015/06/red-hat-summit-syslog-ng-docker-containers/
) my response time will be slower than usual.
