[vchkpw] OpenSolaris 8gb quota displays wrong
Ok, I have an odd problem. I tried both vpopmail 5.4.17 and 5.4.25.
This is functioning on multiple FreeBSD machines, but failing on
OpenSolaris. I've removed my maildirsize file multiple times.
If I look at my account with an 8gb quota, and 923Mb of data (du -h)
with vuserinfo, it reports 100% full.
/usr/local/vpopmail/bin/vuserinfo r...@havokmon.com
name: rick
dir: /usr/home/vpopmail/domains/havokmon.com/rick
quota: 80
usage: 100%
:/usr/home/vpopmail/domains/havokmon.com/rick/Maildir# cat maildirsize
80S
848908105 29941
So that's obviously wrong. Now, if I check my wife's account it's fine:
:/usr/home/vpopmail/domains/havokmon.com/rick/Maildir#
/usr/local/vpopmail/bin/vuserinfo she...@havokmon.com
name: shelby
dir: /usr/home/vpopmail/domains/havokmon.com/shelby
quota: 2
usage: 49%
cat /usr/home/vpopmail/domains/havokmon.com/shelby/Maildir/maildirsize
2S
98759830 1339
If I reduce my quota from 8GB to 900Mb, I get:
quota: 9S
usage: 94%
I've played with my quota a bit, and somewhere around 2.2GB (22)
is where the math starts to fail.
So obviously something is not working right on OpenSolaris.
This works fine on FreeBSD machines, I'm building a new OpenSolaris
server and am using the same MySQL backend, but a copy of the mailbox data.
#uname -a
SunOS sysvolOne 5.11 snv_101b i86pc i386 i86pc Solaris
It seems to be failing in maildirquota.c in qcalc:
while (*quota = '0' *quota = '9')
i=i*10 + (*quota++ - '0');
switch (*quota) {
default:
if (i s)
{
*percentage=105;
return (-1);
}
When I set percentage to 105, that's what my output now says instead of
100. If I multiple i by 100 instead of 10. It says I have 84% used.
So for some reason it seems 932M of 8Gb is calculating to 840%.
I assume it' some kind of compiler issue, but I don't know where to look.

i would guess it fails at 2147483648 and off_t ends up being signed
32bit, so it overflows.
i have no idea why that would happen, or should it happen always with 32
bit kernel.
