Package: uswsusp
Version: 1.0+20110509-2
Severity: normal
The configuration file generated after the first install contains this line:
image size = 2.86942e+09
which is bogus (the program expects an unsigned int, so the value is truncated).
This is generated in uswsusp.config:55 by:
IMAGESIZE=`awk '$1 == "MemTotal:" {print int($2*1024*0.46)}' /proc/meminfo 2>
/dev/null`
My system has 6GB of RAM:
$ grep MemTotal /proc/meminfo
MemTotal: 6091988 kB
So the expression overflows the 'int' and is printed as floating point.
The following statement outputs an integer, but the result is somewhat off
(maybe it gets truncated internally):
awk '$1 == "MemTotal:" {printf("%lu\n", $2*1024*0.46)}' /proc/meminfo
The shell (I've tried both dash and bash) is able to compute the correct value,
like this:
IMAGESIZE=$((`awk '$1 == "MemTotal:" {print $2}' /proc/meminfo` * 1024 / 100 *
46))
