Hi,
I have a program:
#include <err.h>
#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/wait.h>
static void child(unsigned int id)
{
if (setuid(1000))
err(2, "setuid");
sleep(5+id);
exit(id);
}
int main(int argc, char **argv)
{
unsigned int a;
for (a = 0; a < 5; a++)
if (fork() == 0)
child(a);
for (a = 0; a < 5; a++)
wait(NULL);
return 0;
}
============================
In cgconfig.conf there is:
group cpu1 {
cpuset {
cpuset.cpus=1;
cpuset.mems=0;
}
}
group cpu0 {
cpuset {
cpuset.cpus=0;
cpuset.mems=0;
}
}
group others {
cpuset {
cpuset.cpus=0-1;
cpuset.mems=0;
}
}
mount {
cpuset = /mnt/cpu;
}
============================
cgrules.conf are as simple as:
xslaby * cpu0/
man * cpu1/
* * others/
============================
And now if I run the program under root as:
# cgexec -g *:cpu1 --sticky ./fork
the children are moved into the cpu0 group despite the sticky option.
The same as for non-sticky case.
I'm using the latest GIT snapshot.
Any ideas what's wrong?
thanks,
