SELinux warnings: inside open_file_mask_to_av with unknown mode
Last modified: 2008-12-08 08:55:21 EST
Description of problem: With SELinux:targetted/permissive, I am getting hundreds of these warnings printed to the system console and to dmesg. SELinux: WARNING: inside open_file_mask_to_av with unknown mode:c1ff (the "c1ff" part varies between "c1ff" and "c1b6" and maybe others) Version numbers of selected components: selinux-policy-3.6.1-4.fc11.noarch selinux-policy-targeted-3.6.1-4.fc11.noarch kernel-2.6.28-0.106.rc6.git4.fc11.i686 How reproducible: 100%. The messages occur with certain system activity. I get a LOT of these messages during startup, login, and shutdown. But I also see the messages when I run certain commands, e.g. su, rpm, "ls -l" (but not "ls"). Interesting- I get a LOT of the messages whenever I switch virtual terminals (e.g. I press Alt+F3 and I immediately see several screenfuls of these messages get printed on VT3). Additional info: I thought at first it was something in the NSS or PAM modules, specifically my use of nss_ldap. But I disabled nss_ldap and pam_ldap, and I still get these messages. If SELinux is changed to "enforcing" mode, I cannot even log in. If SELinux is changed to "disabled", I no longer see the warnings.
Good news! This morning I pulled some more updates from Rawhide, and the warnings are no longer occurring. Version numbers of selected components: selinux-policy-3.6.1-6.fc11.noarch selinux-policy-targeted-3.6.1-6.fc11.noarch kernel-2.6.28-0.113.rc7.git5.fc11.i686 So please feel free to "resolve" this bug. (I'd do it myself but I'm not familiar enough with policy here.)
