Hi,guys
I am not sure whether it is a bug or it is intentionally designed.
In enterprise linux 4, if we do the following procedure
1. boot a box with CD1
2. type "linux askmethod"
3. choose http method
4. enter http server address and directory
then it would pop up a window asking whether to do the CD media check,
choose skip and it would jump back to step 4.
Then it would go into a dead loop.
below is the code excerpt from the loader2/urlinstall.c
case URL_STAGE_FETCH:
if (FL_TESTING(flags)) {
stage = URL_STAGE_DONE;
dir = 1;
break;
}
/* ok messy - see if we have a stage2 on local CD */
/* before trying to pull one over network */
cdurl = findRedHatCD(location, modInfo, modLoaded,
*modDeps, flags, 0);
if (cdurl) {
if (!loadSingleUrlImage(&ui, "base/product.img", flags,
"/tmp/ramfs/product-disk.img",
"/tmp/product-disk",
"loop7", 1) &&
verifyStamp("/tmp/product-disk")) {
logMessage("Detected stage 2 image on CD");
winStatus(50, 3, _("Media Detected"),
_("Local installation media detected..."), 0);
sleep(3);
newtPopWindow();
stage = URL_STAGE_DONE;
dir = 1;
} else {
/* clean up as we found a cd, but the path was bad */
umountStage2();
umount("/mnt/source");
stage = URL_STAGE_MAIN;
dir = -1;
}
umountLoopback("/tmp/product-disk", "loop7");
unlink("/tmp/ramfs/product-disk.img");
unlink("/tmp/product-disk");
} else {
/* need to find stage 2 on remote site */
So if anaconda found there is a CD , and loadSingleUrlImage fails, it
would set the stage back to URL_STAGE_DONE, which would cause the
install process go back to the beginning, then the user enter http
server/folder name, it goes to the fetch stage again, then
loadSingleUrlImage fails.....
that is where the dead loop comes.
Is this code path intentionally designed?
Thanks
