. Removed kernel.patch since it is no longer required

. Changed SOCK_STREAM to SOCK_DGRAM in syslog.c

 . klogd will only change the console log level if `-c' is supplied

 . syslogd.c by Bill Nottingham <notting@redhat.com>

   Um, if the directory is invalid, the bind() call in
   create_unix_socket fails. Without the return -1, we return the
   invalid fd that we just closed.  When syslogd then starts
   listening, select goes into a hard loop getting EBADF, IIRC.

 . klogd.c by Troels Walsted Hansen <troels@thule.no>

   I found a bug in the sysklogd package version 1.4. When it
   encounters a zero byte in the kernel logging output, the text
   parser enters a busy loop. I came upon it when the 3c59x driver
   from kernel 2.4.0 started outputting two zero bytes for the product
   code of my laptop's 3Com card. It could be argued that the kernel
   should never output zero bytes in the logging info, but obviously
   that will happen from time to time.

   I fear this bug might be considered a security issue as well, if
   the kernel can be coerced to output a zero byte somehow, all kernel
   logging will stop.

   Wolfgang Oertl <Wolfgang.Oertl@uibk.ac.at> had a similar bugfix
   idea

 . klogd.c by Thomas Roessler <roessler@does-not-exist.org>

   Additionally, the patch prevents LogLine from being invoked with a
   negative counter as an argument.

Version 1.4.1
. klogd will set the console log level only if `-c' is given on the
commandline, not overwriting local settings in `/etc/sysctl.conf'.
. Bugfix: klogd will use SOCK_DGRM as well, re-enables kernel logging
. Bugfix: Don't make syslogd fail with broken `-a'
. Bugfix: klogd will skip zero bytes and not enter a busy loop anymore
. Thomas Roessler <roessler@does-not-exist.org>
- Patch to prevent LogLine() from being invoked with a negative
counter as an argument.
Version 1.4
. Skip newline when reading in klog messages
