[Devil-linux-develop] bug in procinfo

[Serge L. <fi...@in...>]

Hello,

Probably I found out a bug in procinfo (not critical, of course)

root@Devil:~ # uptime
 04:17:40 up 65 days, 20:44,  1 user,  load average: 0.00, 0.00, 0.00
root@Devil:~ # procinfo | grep uptime
uptime:   1d  5:47:06.00         context :235715659     interrupts: 29951675

DL 1.3x

Hi  Oliver,

I think it's a counter overflow (probably 32bit counter). If your uptime is more
than ~64 days you will see the bug also. :-)

Moreover I'm not sure it's the first discontinuities, so it may take even less time.

Uh, i test so much in the last days that it will be a problem for me to reach the
counter overflow ;-)

but if it happens i will tell you!

root@Devil:~ # uptime
 05:38:42 up 74 days, 22:05,  1 user,  load average: 0.00, 0.00, 0.00
root@Devil:~ # /tmp/procinfo | grep uptime
uptime:  74d 22:05:37.29         context :245915561     interrupts: 30975704

Patched procinfo shows uptime correctly. I borrowed the patches from Fedora
project and going to add them to DL.
