Subject: [merged][PATCH v3 00/16] Make the user mode driver code a better citizen
Date: Thu, 09 Jul 2020 17:05:09 -0500
Message-ID: <87r1tke44q.fsf_-_@x220.int.ebiederm.org> (raw)
In-Reply-To: <87y2o1swee.fsf_-_@x220.int.ebiederm.org> (Eric W. Biederman's message of "Thu, 02 Jul 2020 11:40:25 -0500")


I have merged all of this into my exec-next tree.

The code is also available on the frozen branch:

   git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git usermode-driver-cleanup

The range-diff from the last posted version is below.

I was asked "Is there a simpler version of this code that could
be used for backports?".  The honest answer is not really.

Fundamentally do_execve_file as it existed prior to this set of changes
breaks a lot of invariants in exec.  The choices are either track down
all of the invariants it violates and fix it, or reorganize the code so
that do_execve_file is unnecessary.  Reorganizing the code was the path
I found simplest and most reliable.  I don't think anyone has tracked
down all of the constraints the code violated.

There is an issue clearly pointed out by Tetsuo Handa that in theory if
there is too long of a delay between closing the file after writing it
and flush_delayed_fput might not synchronize the file synchronously.  I
can not trigger it, and this is the same code path the initramfs relies
upon.  So I think calling flush_delayed_fput is good enough for this set
of changes.

If and when a generally accepted way to remove the theoreticaly race
it will be trivial to fix flush_delayed_fput or replace it and none
of the other logic changes.

Declaring this set of changes done now, allows the work that depends
upon this change to proceed.
