3268f928dc Removed test to detect control characters > 0x20 as this prevented 
characters encoded in UTF-8 to be properly passed through.  This
prevented a security-related patch by Solar Designer (1.29).

ed788aeeff Reset the 'restart' flag immediately after entering the restart code, 
so that subsequent SIGHUPs are able to set it again and cause a new
restart.  This fixes a race condition when somebody sends tons of HUP
signals.

4c09ec0516 Discard any timestamp information found in received syslog messages. 
This will affect local messages sent from a different timezone.  Also
removed code due to the changed semantics.  This was inspired by
Anders Henke from Schlund + Partner AG.

1836e84e94 Ulf Härnhammar <Ulf.Harnhammar.9485@student.uu.se> 
Added boundary check for fscanf() in InitKsyms() and CheckMapVersion()
to prevent an unintended crash when reading an incorrect System.map.

Hello,

I have discovered a potential crash bug in sysklogd. The klogd daemon
doesn't handle really malformed System.map files very well. It has
two fscanf() calls with "%s"format strings that stores to char
sym[512] arrays. This causes a crash if the string field in the
file is longer than that.

Despite being a buffer overflow, this is not a security problem, as
only root can change the System.map file. Nevertheless, I think it
is worth fixing, as the Right Thing for a program should be not to
assume anything about its input and to handle various problems well.

3ee89e2c0b Patch: sysklogd-1.4.1-owl-longjmp.diff from Openwall 
From: Solar Designer <solar@openwall.com>

1. Ensures that "len" is not placed in a register and as such can't be
clobbered by longjmp().  With the particular code, it does not really
matter whether it is clobbered or not, but this avoids the gcc warning.

2. Makes endtty() the signal handler only after the variable that
function uses is initialized.  In the original code, the signal
handler was setup too early and if there would be SIGALRM before
control reaches setjmp(), syslogd would segfault (if not worse).

Basically, this is a minor correctness patch.
