6 irssi_selinux - Security Enhanced Linux Policy for the irssi processes
7
9 Security-Enhanced Linux secures the irssi processes via flexible manda‐
10 tory access control.
11 The irssi processes execute with the irssi_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15 For example:
17 ps -eZ | grep irssi_t
19
23 The irssi_t SELinux type can be entered via the irssi_exec_t file type.
24 The default entrypoint paths for the irssi_t domain are the following:
26 /usr/bin/irssi
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 Policy governs the access confined processes have to files. SELinux
36 irssi policy is very flexible allowing users to setup their irssi pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for irssi:
40 irssi_t
42 Note: semanage permissive -a irssi_t can be used to make the process
44 type irssi_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
50 SELinux policy is customizable based on least access required. irssi
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run irssi with the tightest access possible.
53 If you want to allow the Irssi IRC Client to connect to any port, and
57 to bind to any unreserved port, you must turn on the
58 irssi_use_full_network boolean. Disabled by default.
59 setsebool -P irssi_use_full_network 1
61 If you want to allow all domains to use other domains file descriptors,
65 you must turn on the allow_domain_fd_use boolean. Enabled by default.
66 setsebool -P allow_domain_fd_use 1
68 If you want to allow sysadm to debug or ptrace all processes, you must
72 turn on the allow_ptrace boolean. Disabled by default.
73 setsebool -P allow_ptrace 1
75 If you want to allow system to run with NIS, you must turn on the
79 allow_ypbind boolean. Disabled by default.
80 setsebool -P allow_ypbind 1
82 If you want to allow all domains to have the kernel load modules, you
86 must turn on the domain_kernel_load_modules boolean. Disabled by
87 default.
88 setsebool -P domain_kernel_load_modules 1
90 If you want to allow all domains to execute in fips_mode, you must turn
94 on the fips_mode boolean. Enabled by default.
95 setsebool -P fips_mode 1
97 If you want to enable reading of urandom for all domains, you must turn
101 on the global_ssp boolean. Disabled by default.
102 setsebool -P global_ssp 1
104 If you want to support NFS home directories, you must turn on the
108 use_nfs_home_dirs boolean. Disabled by default.
109 setsebool -P use_nfs_home_dirs 1
111 If you want to support SAMBA home directories, you must turn on the
115 use_samba_home_dirs boolean. Disabled by default.
116 setsebool -P use_samba_home_dirs 1
118
122 The SELinux process type irssi_t can manage files labeled with the fol‐
123 lowing file types. The paths listed are the default paths for these
124 file types. Note the processes UID still need to have DAC permissions.

165 SELinux requires files to have an extended attribute to define the file
166 type.
167 You can see the context of a file using the -Z option to ls
169 Policy governs the access confined processes have to these files.
171 SELinux irssi policy is very flexible allowing users to setup their
172 irssi processes in as secure a method as possible.
173 STANDARD FILE CONTEXT
175 SELinux defines the file context types for the irssi, if you wanted to
177 store files with these types in a diffent paths, you need to execute
178 the semanage command to sepecify alternate labeling and then use
179 restorecon to put the labels on disk.
180 semanage fcontext -a -t irssi_home_t '/srv/myirssi_content(/.*)?'
182 restorecon -R -v /srv/myirssi_content
183 Note: SELinux often uses regular expressions to specify labels that
185 match multiple files.
186 The following file types are defined for irssi:
188 irssi_etc_t
192 - Set files with the irssi_etc_t type, if you want to store irssi files
194 in the /etc directories.
195 irssi_exec_t
199 - Set files with the irssi_exec_t type, if you want to transition an
201 executable to the irssi_t domain.
202 irssi_home_t
206 - Set files with the irssi_home_t type, if you want to store irssi
208 files in the users home directory.
209 Paths:
212 /home/[^/]*/.irssi(/.*)?, /home/staff/.irssi(/.*)?
213 Note: File context can be temporarily modified with the chcon command.
216 If you want to permanently change the file context you need to use the
217 semanage fcontext command. This will modify the SELinux labeling data‐
218 base. You will need to use restorecon to apply the labels.
219
222 semanage fcontext can also be used to manipulate default file context
223 mappings.
224 semanage permissive can also be used to manipulate whether or not a
226 process type is permissive.
227 semanage module can also be used to enable/disable/install/remove pol‐
229 icy modules.
230 semanage boolean can also be used to manipulate the booleans
232 system-config-selinux is a GUI tool available to customize SELinux pol‐
235 icy settings.
