NAME

6       user_execmem_selinux   -   Security   Enhanced  Linux  Policy  for  the
7       user_execmem processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the user_execmem processes via flexible
11       mandatory access control.
12
13       The  user_execmem  processes  execute  with  the user_execmem_t SELinux
14       type. You can check if you have these processes  running  by  executing
15       the ps command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep user_execmem_t
20
21
22

ENTRYPOINTS

24       The  user_execmem_t SELinux type can be entered via the execmem_exec_t,
25       xsession_exec_t, user_home_t file types.
26
27       The default entrypoint paths for the user_execmem_t domain are the fol‐
28       lowing:

PROCESS TYPES

53       SELinux defines process types (domains) for each process running on the
54       system
55
56       You can see the context of a process using the -Z option to ps
57
58       Policy governs the access confined processes have  to  files.   SELinux
59       user_execmem  policy  is  very  flexible  allowing users to setup their
60       user_execmem processes in as secure a method as possible.
61
62       The following process types are defined for user_execmem:
63
64       user_execmem_t
65
66       Note: semanage permissive -a user_execmem_t can be  used  to  make  the
67       process type user_execmem_t permissive. SELinux does not deny access to
68       permissive process types, but the AVC (SELinux  denials)  messages  are
69       still generated.
70
71

BOOLEANS

73       SELinux   policy  is  customizable  based  on  least  access  required.
74       user_execmem policy is extremely flexible and has several booleans that
75       allow you to manipulate the policy and run user_execmem with the tight‐
76       est access possible.
