Eric Paris 915b5f885f libsemanage: add ignoredirs config for genhomedircon
For a long time /root has been treated differently in Red Hat
Distributions then upstream policy.

We do not want to label /root the same as a users homedir.  Because of
this we have carried a patch in libsemanage/genhomedircon.c to ignore
/root.

This patch adds a flag to semanage.conf, ignoredirs.  That will allow
distributions or users to specify directories that genhomedircon
should ignore when setting up users homedir labeling.

.SH NAME
semanage.conf \- global configuration file for the SELinux Management library
.SH DESCRIPTION
.PP
The
.BR semanage.conf
file is usually located under the directory /etc/selinux and it is used for run-time configuration of the
behavior of the SELinux Management library.
.PP
Each line should contain a configuration parameter followed by the equal sign ("=") and then followed by the configuration value for that
parameter. Anything after the "#" symbol is ignored similarly to empty lines.
.PP
The following parameters are allowed:
.RS
.TP
.B module-store
Specify how the SELinux Management library should interact with the SELinux policy store. When set to "direct", the SELinux
Management library writes to the SELinux policy module store directly (this is the default setting).
Otherwise a socket path or a server name can be used for the argument.
If the argument begins with "/" (as in "/foo/bar"), it represents the path to a named socket that should be used to connect the policy management
server.
If the argument does not begin with a "/" (as in "foo.com:4242"), it should be interpreted as the name of a remote policy management server
to be used through a TCP connection (default port is 4242 unless a different one is specified after the server name using the colon to separate
the two fields).
.TP
.B policy-version
When generating the policy, by default
.BR semanage
will set the policy version to POLICYDB_VERSION_MAX, as defined in <sepol/policydb/policydb.h>. Change this setting if a different
version needs to be set for the policy.
.TP
.B expand-check
Whether or not to check "neverallow" rules when executing all
.BR semanage
command. It can be set to either "0" (disabled) or "1" (enabled) and by default it is enabled. There might be a large
penalty in execution time if this option is enabled.
.TP
.B file-mode
By default the permission mode for the run-time policy files is set to 0644.
.TP
.B save-previous
It controls whether the previous module directory is saved after a successful commit to the policy store and it can be set to
either "true" or "false". By default it is set to "false" (the previous version is deleted).
.TP
.B save-linked
It controls whether the previously linked module is saved (with name "base.linked") after a successful commit to the policy store.
It can be set to either "true" or "false" and by default it is set to "false" (the previous module is deleted).
.TP
.B ignoredirs
List, separated by ";", of directories to ignore when setting up users homedirs.
Some distributions use this to stop labeling /root as a homedir.
.TP
.B usepasswd
Whether or not to enable the use getpwent() to obtain a list of home directories to label. It can be set to either "true" or "false".
By default it is set to "true".
.TP
.B disable-genhomedircon
It controls whether or not the genhomedircon function is executed when using the
.BR semanage
command and it can be set to either "false" or "true". By default the genhomedircon functionality is enabled (equivalent
to this option set to "false").
.TP
.B handle-unknown
This option controls the kernel behavior for handling permissions defined in the kernel but missing from the actual policy.
It can be set to "deny", "reject" or "allow".
.TP
.B bzip-blocksize
It should be in the range 0-9. A value of 0 means no compression. By default the bzip block size is set to 9 (actual block
size value is obtained after multiplication by 100000).
.TP
.B bzip-small
When set to "true", the bzip algorithm shall try to reduce its system memory usage. It can be set to either "true" or "false" and
by default it is set to "false".
