NAME

       seinfoflow - Information flow analysis for SELinux policies

SYNOPSIS

       seinfoflow [OPTIONS] -m MAP -s SOURCE [-t TARGET (-S|-A LIMIT)] [EXCLUDE [EXCLUDE ...]]

DESCRIPTION

       seinfoflow  is  a  command  line  tool  that  allows  the user to perform information flow
       analyses on an SELinux policy.

POLICY

       A single file containing a binary policy. This file is usually named by version  on  Linux
       systems,  for  example, policy.30. This file is usually named sepolicy on Android systems.
       If no policy file is provided, seinfoflow will  search  for  the  policy  running  on  the
       current  system.  If  no  policy  can be found, seinfoflow will print an error message and
       exit.

OPTIONS

   Analysis Settings
       -p POLICY
              Specify the policy to analyze. If none is specified, seinfoflow will search for the
              policy running on the current system.

       -m MAP Specify  the  path  to  the  permission  map  file  to  use in the information flow
              analysis.

       -s SOURCE
              Specify the source type to use in the information flow analysis.

       -t TARGET
              Specify the target type to use in the information flow analysis. Using this  option
              will also require specifying an analysis algorithm.

   Analysis Algorithms
       seinfoflow  uses  graph  algorithms  to  analyze  the information flow paths of an SELinux
       policy.  The following algorithms are options for determining paths from a source type  to
       a target type.

       -S     Print  the  shortest  information  flow  path(s) from the source type to the target
              type.  If multiple paths have the same length, all will be displayed.

       -A LIMIT
              Print all information flow path(s) up  to  LIMIT  steps  long.   Depending  on  the
              connectiveness of the policy, a limit of 5 or more may be extremely expensive.

   Analysis Options
       -w MIN_WEIGHT
              Specify  the  minimum  permission  weight  to consider for the analysis (1-10). The
              default is 3.

       -l LIMIT_FLOWS
              Specify the  maximum  number  of  information  flows  to  output.  The  default  is
              unlimited.

       EXCLUDE
              A space-separated list of types to exclude from the analysis.

   General Options
       --stats
              Print information flow graph statistics at the end of the analysis.

       -h, --help
              Print help information and exit.

       --version
              Print version information and exit.

       -v, --verbose
              Print additional informational messages.

       --debug
              Enable debugging output.
