Red Hat Bugzilla – Bug 1489989
File Permission set to 666 or 777(world writable files) on the yum cache files, these are reverted even after changing
Last modified: 2018-04-10 08:18:11 EDT
Description of problem: - rhn_check command executed in rhnsd daemon changed the file permission in yum cache into 0666. - This happened when the cache was recreated. rhn_check can recreate it. - When a new file was created in rhnsd, the file was created with mode=0666. Because umask=0000. (comment #56 and #57) - rhnsd is running with umask=0000 in RHEL7. it's running with umask=0022 in RHEL6. - On umask=0000, the default permission of the new file should be 0666. So, this matches their problem. - umask is set in latest rhnsd itself in RHEL7. (C#57) The code to set it doesn't exist in rhnsd of RHEL6. - This should be regression. (need to check) rhnsd-5.0.13-5.el7: umask(0) is NOT executed in main() of rhnsd.c. rhnsd-5.0.13-7.el7: umask(0) is executed in main() of rhnsd.c. Version-Release number of selected component (if applicable): rhnsd-5.0.13 How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
