Hello. Version 1.6.6 fixed 3 bugs which existed in version 1.6.0 - 1.6.5 . Fix 1: Since MAX_GRANT_LOG and MAX_REJECT_LOG parameters were not functional, the system will crash due to out of memory if access logs are not consumed by ccs-auditd program. This bug was introduced in version 1.6.5 . Fix 2: In SYAORAN filesystem, error message was printed when access was granted, and error message was not printed when access was rejected. This bug was introduced in version 1.6.0 . Fix 3: If only allow_read/write is given against some pathname, opening that pathname for both reading and writing is granted, but opening that pathname for only reading or only writing are rejected. This bug was introduced in version 1.6.0 . ccs-patch-1.6.6-20090202.tar.gz MD5: cceb1731d3720030eac34ed128848b32 ccs-tools-1.6.6-20090202.tar.gz MD5: ee6900297b263bebe19156c32c652f36 I'll start building binary packages. Regards.
