6ef13eeda7 libselinux: man: Fix man pages formatting
- Add man page sections '(N)' to external references, and '()' on
  functions described in the same man page.
- Escape minus signs when those are expected to be used on the command
  line or files.
- Mark files and variables in italic; Note headings, function names,
  constants, program options and man page references in bold.
- Do not justify and hyphenate SEE ALSO section, and avoid hyphenation
  on symbol names by prepending them with \%.
- Remove trailing dot from NAME section description.
- Split sections with a no-op command '.', to visually distinguish them
  but to avoid introducing spurious vertical space in the formatted
  output.
- Add explicit .sp commands in the SYNOPSIS section between function
  prototypes, and fix space placement in function protoypes.
- Split header includes with .br (instead of the explicit or implicit
  .sp) so that they are vertically contiguous.
- Add missing {} around SELINUXTYPE and POLICYTYPE variable text in
  paths.
- Remove unneeded formatting commands.
- Remove spurious blank lines.

70aeeb918a This patch allows selabel_*() interfaces to provide an expected security context
for the given database object identified by its name and object class.
It is necessary to implement a feature something like the restorecon on databases.

The specfile shall be described as follows:
  ------------------------
  #
  # The specfile for database objects
  # (for SE-PostgreSQL)
  #
  # <object class> <object name> <security context>
  #
  db_database     *               system_u:object_r:sepgsql_db_t:s0

  db_schema       *.pg_catalog    system_u:obejct_r:sepgsql_sys_schema_t:s0
  db_schema       *.*             system_u:object_r:sepgsql_schema_t:s0

  db_table        *.pg_catalog.*  system_u:object_r:sepgsql_sysobj_t:s0
  db_table        *.*.*           system_u:object_r:sepgsql_table_t:s0
  ------------------------

- All the characters after the '#' are ignored.
- Wildcards ('*' and '?') are available.
- It returns the first match security context.

Note that hierarchy of the namespace of database objects depends on RDBMS.
So, author of the specfile needs to write correct patterns which are suitable
for the target RDBMS. The patched selabel_*() interfaces don't have any
heuristics for the namespace hierarchy to be suitable for widespread RDBMSs.
In the case of SE-PgSQL, when we lookup an expected security context for the
'my_table' table in the 'public' schema and 'postgres' database, the caller
shall provide 'postgres.public.my_table' as a key.

In the default, it tries to read a specfile which maps database objects and security
context from the /etc/selinux/$POLICYTYPE/contexts/sepgsql_contexts.
Note that when another RDBMS uses this interface, it needs to give an explicit
SELABEL_OPT_PATH option on the selabel_open().
