RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Alexander Todorov 2010-07-07 15:58:46 UTC
+++ This bug was initially created as a clone of Bug #599457 +++

Description of problem:


Version-Release number of selected component (if applicable): 13.42


How reproducible:


Steps to Reproduce:
1. create a new grub entry with vmlinuz and initrd.img from an install disk
2. reboot and select above entry as boot option
3. select "url" among install-source options
4. configure ethernet interface
5. specify url for obtaining install.img

installer crashes after retrieving install.img  


Additional info:
Seen at prompt on crash:

43         setenv("LD_LIBRARY_PATH", LIBPATH, 1);
44         execl("/sbin/load_policy",

46         logMessage(ERROR, "exec of load_policy failed: %m");
47         exit(1);
48     }

This is a pretty strange place to get a crash, but it seems obvious what the problem is - load_policy failed.  When you get this crash, can you jump over to tty3 and tty4, take a picture, and attach them to this bug report?

I've hit this with snapshot #7 on a ASUS eeePC (i386) laptop. Tre backtrace happend right after install.img was downloaded. Looks like:

Loader exited unexpectedly! Backtrace:
/sbin/loader[0x804f9ae]

I will try to attach screenshots of tty3 and 4 later. Right now I don't have a camera available.

And from loader/selinux.c:

 38     int pid, status;
 39 
 40     logMessage(INFO, "Loading SELinux policy");
 41 
 42     if (!(pid = fork())) {
 43         setenv("LD_LIBRARY_PATH", LIBPATH, 1);
 44         execl("/sbin/load_policy",
 45               "/sbin/load_policy", "-q", NULL);
 46         logMessage(ERROR, "exec of load_policy failed: %m");
 47         exit(1);
 48     }
 49 
 50     waitpid(pid, &status, 0);
 51     if (WIFEXITED(status) && (WEXITSTATUS(status) != 0))
 52         return 1;
 53 
 54     return 0;

Reassigning to policycoreutils.

David, do you have any idea what is going on?

Scratch original analysis.  This is not a load_policy problem.  Looks like you're using the wrong install.img.  'Exec format error' means you likely pointed the install media to an x86_64 tree.
