Subject: 2.6.33-rc4 i686 clone function looping (?)
Date: Mon, 18 Jan 2010 17:04:03 -0500 [thread overview]
Message-ID: <1263852243.4745.363.camel@Mercier.safe.ca> (raw)
Hello,
Same physical system and configuration
(small system in 32 Bits i686 mode).
2.6.32.3: working A_one.
2.6.33-rc4: clone call, looping and
taking ALL CPU cycle.
Here is code used.
;======================================
cloneflg=SIGCHLD|__WCLONE;
cloneflg|=CLONE_NEWNET|CLONE_NEWIPC|CLONE_NEWNS|CLONE_NEWPID|
CLONE_NEWUTS;
clonestk=(char *)malloc(STKSIZE)
......
;--------------------------------------
if (argv[0]!=(char *)0) { /*always */
static ARGTYP args;
args.mspid=getpid();
args.arch=cntarch;
args.argc=argc;
args.argv=argv;
if ((cpid=clone(&doboot,(void *)(clonestk
+STKSIZE),cloneflg,(void *)&args))<0) {
(void) apl_alert(0,"%s, Unable to clone %s container process
(error=<%s>)",
appname,argv[0],strerror(errno));
;======================================
There is some difference within .config file between
both kernel I regenerated, but I do not believe they
are meaningful for the clone/cgroup/veth/bridge functions.
I can provide config diff if needed.
Do we have a real problem with 2.6.33-rc4?? or did I missed
something? could someone confirm trouble with clone call?
Thanks.

A bientôt
