Red Hat Bugzilla – Bug 212062
FC6 kernel locks up right away on setting of rodata to read only
Last modified: 2015-01-04 17:29:14 EST
Description of problem:
Kernel hangs on start up due to execshield and readonly data.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
The problem is that the code in change_page_attr checks to see if the ro
data section is being change to PAGE_KERNEL_RO. I believe what should be
done is to check to see if this section is being set to RW.
Attached is a patch.
