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 of problem:

A customer who enabled fapolicyd service hit boot issues after a kernel update: the initramfs was "corrupted" and not including many required libraries, due to "ldd" not working anymore.

In a terminal, executing "ldd" shows unexpected result:

  # ldd /bin/bash
  	not a dynamic executable


  # dracut -f /tmp/initramfs.img $(uname -r)
  # ll /tmp/initramfs.img
  -rw-------. 1 root root 11280564 Mar 10 15:17 /tmp/initramfs.img

  --> invalid size (too small)

  # lsinitrd /tmp/initramfs.img | grep libc.so
  
  --> no output, was expecting:

  -rw-r--r--   1 root     root          253 Nov  6 16:07 usr/lib64/libc.so
  lrwxrwxrwx   1 root     root           12 Nov  6 16:07 usr/lib64/libc.so.6 -> libc-2.28.so



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

fapolicyd-0.8.10-3.el8_1.1.x86_64


How reproducible:

ALWAYS


Steps to Reproduce:
1. Start fapolicyd

  # systemctl start fapolicyd

2. Execute dracut or ldd

  # ldd /bin/bash

Actual results:

  "not a dynamic executable"

  OR

  "
  linux-vdso.so.1 (0x00007ffce8ff7000)
  libtinfo.so.6 => not found
  libdl.so.2 => not found
  libc.so.6 => not found
  "

Rule being hit when executing "ldd /bin/bash" is:

# Prevent execution by ld.so
deny_audit pattern=ld_so all

Mar 10 15:36:33 vm-rhel8 fapolicyd[16127]: rule:3 dec=deny_audit auid=0 pid=16152 exe=/usr/lib64/ld-2.28.so file=/usr/bin/bash

Is fapolicyd just going to stay disabled?

Hi,

The BZ has been closed because the fix will be delivered as part of fapolicyd-0.8.10-3.el8_1.3
