Oh, thanks. I forgot to update Makefile and ccs-tools.spec .

I started to implement ccs-patternize logic. I added /etc/ccs/tools/patternize.conf and registered some patterns. Steps to patternize (as of revision 4182) would look like (1) Save current policy by doing "ccs-savepolicy -d > /etc/ccs/domain_policy.tmp". (2) Browse /etc/ccs/domain_policy.tmp and determine how to patternize. (3) Edit /etc/ccs/tools/patternize.conf as needed. (4) Convert by doing "ccs-patternize < /etc/ccs/domain_policy.tmp > /etc/ccs/domain_policy.new". (5) Generate diff by doing "ccs-diffpolicy /etc/ccs/domain_policy.tmp /etc/ccs/domain_policy.new > /etc/ccs/domain_policy.diff". (6) Browse /etc/ccs/domain_policy.diff and commit changes by doing "ccs-loadpolicy -d < /etc/ccs/domain_policy.diff". Currently, I implemented six types. Type 1 : Exact pathname match file_pattern proc:/self/fd/\$ will replace (e.g.) proc:/self/fd/0 with proc:/self/fd/\$ . This is what it was until TOMOYO 1.7 . Type 2 : Heading pathname match head_pattern proc:/\$/ will replace (e.g.) proc:/123/status with proc:/\$/status . This is intended for reducing number of file_pattern entries by grouping pathnames where only directory part needs to be patternized. Type 3 : Trailing pathname match tail_pattern /etc/mtab~\$ will replace (e.g.) dev(8,1):/etc/mtab~456 with dev(8,1):/etc/mtab~\$ . This is intended for CONFIG_SECURITY_PATH=n kernels where we can't obtain absolute pathnames regarding directory entry modification operations (e.g. "file create" and "file rename"). Type 4 : Exact pathname match with grouping path_group GROUP1 /tmp/php\?\?\?\?\?\? will replace (e.g.) /tmp/phpZjk1k3 with @GROUP1 . This syntax is identical with path_group directive in exception policy. Type 5 : Exact number match with grouping number_group GROUP2 0-100 number_group GROUP2 100-200 will replace integers between 0-100 or 100-200 with @GROUP2 . This syntax is identical with number_group directive in exception policy. Type 6 : Exact IP address match with grouping address_group LOCALHOST 127.0.0.1 address_group LOCALHOST 0:0:0:0:0:0:0:1 will replace IP addresses 127.0.0.1 or 0:0:0:0:0:0:0:1 with @LOCALHOST . This syntax is identical with address_group directive in exception policy. Maybe we want to unify these syntax like (e.g.) file_pattern proc:/self/fd/\$ proc:/self/fd/\$ head_pattern proc:/\$/ proc:/\$/ tail_pattern /etc/mtab~\$ /etc/mtab~\$ file_pattern @GROUP1 /tmp/php\?\?\?\?\?\? number_pattern @GROUP2 0-100 number_pattern @GROUP2 100-200 address_pattern @LOCALHOST 127.0.0.1 address_pattern @LOCALHOST 0:0:0:0:0:0:0:1 . Also, maybe we want domainname matching like ccs-auditd's sorting rule. Preferences?/Comments?/Suggestions?
