* seq_file: constify seq_operationsJames Morris2009-09-231-2/+2
| | | | | | | | | | | | | | Make all seq_operations structs const, to help mitigate against revectoring user-triggerable function pointers. This is derived from the grsecurity patch, although generated from scratch because it's simpler than extracting the changes from there.

| * IMA: Add __init notation to ima functionsEric Paris2009-05-221-1/+1
| | | | | | | | | | | | | | | | | | A number of IMA functions only used during init are not marked with __init. Add those notations so they are freed automatically. Signed-off-by: Eric Paris <eparis@redhat.com> Acked-by: Mimi Zohar <zohar@us.ibm.com> Signed-off-by: James Morris <jmorris@namei.org>
| * IMA: remove read permissions on the ima policy fileEric Paris2009-05-151-1/+5
| | | | | | | | | | | | | | | | | | | | | | The IMA policy file does not implement read. Trying to just open/read/close the file will load a blank policy and you cannot then change the policy without a reboot. This removes the read permission from the file so one must at least be attempting to write...
