f4c4335a4a Add context info to OAT_POST_CREATE security hook
... and have sepgsql use it to determine whether to check permissions
during certain operations.  Indexes that are being created as a result
of REINDEX, for instance, do not need to have their permissions checked;
they were already checked when the index was created.

aa2b237ce5 sepgsql cleanups.
This is needed to match recent changes elsewhere.  Along the way, some
renaming for clarity.

d7c734841b Reduce messages about implicit indexes and sequences to DEBUG1.
Per recent discussion on pgsql-hackers, these messages are too
chatty for most users.

8fbe5a317d Fix error message for COMMENT/SECURITY LABEL ON COLUMN xxx IS 'yyy'
When the column name is an unqualified name, rather than table.column,
the error message complains about too many dotted names, which is
wrong.  Report by Peter Eisentraut based on examination of the
sepgsql regression test output, but the problem also affects COMMENT.
New wording as suggested by Tom Lane.

523176cbf1 sepgsql_setcon().
This is intended as infrastructure to allow sepgsql to cooperate with
connection pooling software, by allowing the effective security label
to be set for each new connection.

d44a3fb55d sepgsql: Move some code from hooks.c to label.c
This is some preliminary refactoring related to a pending patch
to allow sepgsql-enable sessions to make dynamic label transitions.
But this commit doesn't involve any functional change: it just puts
some bits of code in more logical places.

cc4ff8742b Take sepgsql regression tests out of the regular regression test mechanism.
Because these tests require root privileges, not to mention invasive
changes to the security configuration of the host system, it's not
reasonable for them to be invoked by a regular "make check" or "make
installcheck".  Instead, dike out the Makefile's knowledge of the tests,
and change chkselinuxenv (now renamed "test_sepgsql") into a script that
verifies the environment is workable and then runs the tests.  It's
expected that test_sepgsql will only be run manually.

While at it, do some cleanup in the error checking in the script, and
do some wordsmithing in the documentation.

3d14bd2563 Fix "is db labeled test?" in chkselinuxenv script.
Don't test whether the number of labels is numerically equal to zero;
count(*) isn't going return zero anyway, and the current coding blows
up if it returns an empty string or an error.

d1d388603e Fix pgxs.mk to always add --dbname=$(CONTRIB_TESTDB) to REGRESS_OPTS.
The previous coding resulted in contrib modules unintentionally overriding
the use of CONTRIB_TESTDB.  There seems no particularly good reason to
allow that (after all, the makefile can set CONTRIB_TESTDB if that's really
what it intends).

In passing, document REGRESS_OPTS where the other pgxs.mk options are
documented.

Back-patch to 9.1 --- in prior versions, there were no cases of contrib
modules setting REGRESS_OPTS without including the --dbname switch, so
while the coding was fragile there was no actual bug.

a4b3feebc4 Clean up 'chkselinuxenv' script.
Eliminate dependencies on "which", as we don't really need that to be
installed for proper testing.  Don't number the tests, as that increases
the footprint of every patch that wants to add or remove tests.  Make
the test output more informative, so that it's a bit easier to see what
went right (or wrong).  Spelling and grammar improvements.

10c378f235 Fix contrib/sepgsql and contrib/xml2 to always link required libraries.
contrib/xml2 can get by without libxslt; the relevant features just
won't work.  But if doesn't have libxml2, or if sepgsql doesn't have
libselinux, the link succeeds but the module then fails to work at load
time.  To avoid that, link the require libraries unconditionally, so
that it will be clear at link-time that there is a problem.

Per discussion with Tom Lane and KaiGai Kohei.

2594cf0e8c Revise the API for GUC variable assign hooks.
The previous functions of assign hooks are now split between check hooks
and assign hooks, where the former can fail but the latter shouldn't.
Aside from being conceptually clearer, this approach exposes the
"canonicalized" form of the variable value to guc.c without having to do
an actual assignment.  And that lets us fix the problem recently noted by
Bernd Helmle that the auto-tune patch for wal_buffers resulted in bogus
log messages about "parameter "wal_buffers" cannot be changed without
restarting the server".  There may be some speed advantage too, because
this design lets hook functions avoid re-parsing variable values when
restoring a previous state after a rollback (they can store a pre-parsed
representation of the value instead).  This patch also resolves a
longstanding annoyance about custom error messages from variable assign
hooks: they should modify, not appear separately from, guc.c's own message
about "invalid parameter value".

968bc6fac9 sepgsql, an SE-Linux integration for PostgreSQL
This is still pretty rough - among other things, the documentation

but this gets the basic framework in place.
