Audit: clean up all op= output to include string quoting
A number of places in the audit system we send an op= followed by a string that includes spaces. Somehow this works but it's just wrong. This patch moves all of those that I could find to be quoted. Example: Change From: type=CONFIG_CHANGE msg=audit(1244666690.117:31): auid=0 ses=1 subj=unconfined_u:unconfined_r:auditctl_t:s0-s0:c0.c1023 op=remove rule key="number2" list=4 res=0 Change To: type=CONFIG_CHANGE msg=audit(1244666690.117:31): auid=0 ses=1 subj=unconfined_u:unconfined_r:auditctl_t:s0-s0:c0.c1023 op="remove rule" key="number2" list=4 res=0 Signed-off-by: Eric Paris <eparis@redhat.com>
