Preface
-------
These patches are for binding the rlimit counters to a user in user namespace.
This patch set can be applied on top of:

git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git v5.12-rc4

Problem
-------
The RLIMIT_NPROC, RLIMIT_MEMLOCK, RLIMIT_SIGPENDING, RLIMIT_MSGQUEUE rlimits
implementation places the counters in user_struct [1]. These limits are global
between processes and persists for the lifetime of the process, even if
processes are in different user namespaces.

To illustrate the impact of rlimits, let's say there is a program that does not
fork. Some service-A wants to run this program as user X in multiple containers.
Since the program never fork the service wants to set RLIMIT_NPROC=1.

service-A
 \- program (uid=1000, container1, rlimit_nproc=1)
 \- program (uid=1000, container2, rlimit_nproc=1)

The service-A sets RLIMIT_NPROC=1 and runs the program in container1. When the
service-A tries to run a program with RLIMIT_NPROC=1 in container2 it fails
since user X already has one running process.

The problem is not that the limit from container1 affects container2. The
problem is that limit is verified against the global counter that reflects
the number of processes in all containers.

This problem can be worked around by using different users for each container
but in this case we face a different problem of uid mapping when transferring
files from one container to another.

Eric W. Biederman mentioned this issue [2][3].

Introduced changes
------------------
To address the problem, we bind rlimit counters to user namespace. Each counter
reflects the number of processes in a given uid in a given user namespace. The
result is a tree of rlimit counters with the biggest value at the root (aka
init_user_ns). The limit is considered exceeded if it's exceeded up in the tree.

Changelog
---------
v10:
* Fixed memory leak in __sigqueue_alloc.
* Handled an unlikely situation when all consumers will return ucounts at once.
* Addressed other review comments from Eric W. Biederman.

v9:
* Used a negative value to check that the ucounts->count is close to overflow.
* Rebased onto v5.12-rc4.

v8:
* Used atomic_t for ucounts reference counting. Also added counter overflow
  check (thanks to Linus Torvalds for the idea).
* Fixed other issues found by lkp-tests project in the patch that Reimplements
  RLIMIT_MEMLOCK on top of ucounts.

v7:
* Fixed issues found by lkp-tests project in the patch that Reimplements
  RLIMIT_MEMLOCK on top of ucounts.

v6:
* Fixed issues found by lkp-tests project.
* Rebased onto v5.11.

v5:
* Split the first commit into two commits: change ucounts.count type to atomic_long_t
  and add ucounts to cred. These commits were merged by mistake during the rebase.
* The __get_ucounts() renamed to alloc_ucounts().
* The cred.ucounts update has been moved from commit_creds() as it did not allow
  to handle errors.
* Added error handling of set_cred_ucounts().

v4:
* Reverted the type change of ucounts.count to refcount_t.
* Fixed typo in the kernel/cred.c

v3:
* Added get_ucounts() function to increase the reference count. The existing
  get_counts() function renamed to __get_ucounts().
* The type of ucounts.count changed from atomic_t to refcount_t.
* Dropped 'const' from set_cred_ucounts() arguments.
* Fixed a bug with freeing the cred structure after calling cred_alloc_blank().
* Commit messages have been updated.
* Added selftest.

v2:
* RLIMIT_MEMLOCK, RLIMIT_SIGPENDING and RLIMIT_MSGQUEUE are migrated to ucounts.
* Added ucounts for pair uid and user namespace into cred.
* Added the ability to increase ucount by more than 1.

v1:
* After discussion with Eric W. Biederman, I increased the size of ucounts to
  atomic_long_t.
* Added ucount_max to avoid the fork bomb.

RLIMIT_MSGQUEUE and RLIMIT_MEMLOCK use unsigned long to store their
counters. As a preparation for moving rlimits based on ucounts, we need
to increase the size of the variable to long.

For RLIMIT_NPROC and some other rlimits the user_struct that holds the
global limit is kept alive for the lifetime of a process by keeping it
in struct cred. Adding a pointer to ucounts in the struct cred will
allow to track RLIMIT_NPROC not only for user in the system, but for
user in the user_namespace.

Updating ucounts may require memory allocation which may fail. So, we
cannot change cred.ucounts in the commit_creds() because this function
cannot fail and it should always return 0. For this reason, we modify
cred.ucounts before calling the commit_creds().

Changelog

v6:
* Fix null-ptr-deref in is_ucounts_overlimit() detected by trinity. This
  error was caused by the fact that cred_alloc_blank() left the ucounts
  pointer empty.

The current implementation of the ucounts reference counter requires the
use of spin_lock. We're going to use get_ucounts() in more performance
critical areas like a handling of RLIMIT_SIGPENDING.

Now we need to use spin_lock only if we want to change the hashtable.

v10:
* Always try to put ucounts in case we cannot increase ucounts->count.
  This will allow to cover the case when all consumers will return
  ucounts at once.

v9:
* Use a negative value to check that the ucounts->count is close to
  overflow.

The rlimit counter is tied to uid in the user_namespace. This allows
rlimit values to be specified in userns even if they are already
globally exceeded by the user. However, the value of the previous
user_namespaces cannot be exceeded.

To illustrate the impact of rlimits, let's say there is a program that
does not fork. Some service-A wants to run this program as user X in
multiple containers. Since the program never fork the service wants to
set RLIMIT_NPROC=1.

service-A
 \- program (uid=1000, container1, rlimit_nproc=1)
 \- program (uid=1000, container2, rlimit_nproc=1)

The service-A sets RLIMIT_NPROC=1 and runs the program in container1.
When the service-A tries to run a program with RLIMIT_NPROC=1 in
container2 it fails since user X already has one running process.

We cannot use existing inc_ucounts / dec_ucounts because they do not
allow us to exceed the maximum for the counter. Some rlimits can be
overlimited by root or if the user has the appropriate capability.

rlimit values to be specified in userns even if they are already
globally exceeded by the user. However, the value of the previous
user_namespaces cannot be exceeded.

The rlimit counter is tied to uid in the user_namespace. This allows
rlimit values to be specified in userns even if they are already
globally exceeded by the user. However, the value of the previous
user_namespaces cannot be exceeded.

v10:
* Fix memory leak on get_ucounts failure.

The rlimit counter is tied to uid in the user_namespace. This allows
rlimit values to be specified in userns even if they are already
globally exceeded by the user. However, the value of the previous
user_namespaces cannot be exceeded.

Changelog
v8:
* Fix issues found by lkp-tests project.

v7:
* Keep only ucounts for RLIMIT_MEMLOCK checks instead of struct cred.

v6:
* Fix bug in hugetlb_file_setup() detected by trinity.

The ns->ucount_max[] is signed long which is less than the rlimit size.
We have to protect ucount_max[] from overflow and only use the largest
value that we can hold.

On 32bit using "long" instead of "unsigned long" to hold the counts has
the downside that RLIMIT_MSGQUEUE and RLIMIT_MEMLOCK are limited to 2GiB
instead of 4GiB. I don't think anyone cares but it should be mentioned
in case someone does.

The RLIMIT_NPROC and RLIMIT_SIGPENDING used atomic_t so their maximum
hasn't changed.

Ouch.

I *think* this test may be testing "send so many signals that it
triggers the signal queue overflow case".

And I *think* that the performance degradation may be due to lots of
unnecessary allocations, because ity looks like that commit changes
__sigqueue_alloc() to do

        struct sigqueue *q = kmem_cache_alloc(sigqueue_cachep, flags);

*before* checking the signal limit, and then if the signal limit was
exceeded, it will just be free'd instead.

The old code would check the signal count against RLIMIT_SIGPENDING
*first*, and if there were m ore pending signals then it wouldn't do
anything at all (including not incrementing that expensive atomic
count).

Also, the old code was very careful to only do the "get_user()" for
the *first* signal it added to the queue, and do the "put_user()" for
when removing the last signal. Exactly because those atomics are very
expensive.

The new code just does a lot of these atomics unconditionally.

I dunno. The profile data in there is a bit hard to read, but there's
a lot more cachee misses, and a *lot* of node crossers:

and (probably as a result) average instruction costs have gone up enormously:

and it does seem to be at least partly about "put_ucounts()":

and a lot of "get_ucounts()".

But it may also be that the new "get sigpending" is just *so* much
more expensive than it used to be.

Yes and right now I'm trying to rewrite this patch.

Thanks for decrypting this! I spent some time to understand this report
and still wasn't sure I understood it.

We were cautiously optimistic when no test problems showed up from
the last posting that there was nothing to look at here.

Unfortunately it looks like the bots just missed the last posting. 

So it seems we are finally pretty much at correct code in need
of performance tuning.

This is an interesting test in a lot of ways as it is testing the
synchronous signal delivery path caused by an exception.  The test
is either executing *ptr = 0 (where ptr points to a read-only page)
or it executes an x86 instruction that is excessively long.

I have found the code but I haven't figured out how it is being
called yet.  The core loop is just:
	for(;;) {
		sigaction(SIGSEGV, &action, NULL);
		sigaction(SIGILL, &action, NULL);
		sigaction(SIGBUS, &action, NULL);

		ret = sigsetjmp(jmp_env, 1);
		if (done())
                	break;
		if (ret) {
                	/* verify signal */
                } else {
                	*ptr = 0;
                }
	}

Code like that fundamentally can not be multi-threaded.  So the only way
the sigpending limit is being hit is if there are more processes running
that code simultaneously than the size of the limit.

Further it looks like stress-ng pushes RLIMIT_SIGPENDING as high as it
will go before the test starts.

Yes. That seems a likely culprit.

That too is possible.

That node-load-misses number does look like something is bouncing back
and forth between the nodes a lot more.  So I suspect stress-ng is
running multiple copies of the sigsegv test in different processes at
once.



That really suggests cache line ping pong from get_ucounts and
incrementing sigpending.

It surprises me that obtaining the cache lines exclusively is
the dominant cost on this code path but obtaining two cache lines
exclusively instead of one cache cache line exclusively is consistent
with a causing the exception delivery to take nearly twice as long.

For the optimization we only care about the leaf count so with a little
care we can restore the optimization.  So that is probably the thing
to do here.  The fewer changes to worry about the less likely to find
surprises.



That said for this specific case there is a lot of potential room for
improvement.  As this is a per thread signal the code update sigpending
in commit_cred and never worry about needing to pin the struct
user_struct or struct ucounts.  As this is a synchronous signal we could
skip the sigpending increment, skip the signal queue entirely, and
deliver the signal to user-space immediately.  The removal of all cache
ping pongs might make it worth it.

There is also Thomas Gleixner's recent optimization to cache one
sigqueue entry per task to give more predictable behavior.  That
would remove the cost of the allocation.

You mean something like this ? I did it on top of Thomas Gleixner's
patches.

this report is upon v10. do you have newer version which hope bot test?

please be noted, sorry to say, due to various reasons, it will be a
big challenge for us to capture each version of a patch set.

e.g. we didn't make out a similar performance regression for
v8/v9 version of this one..

Yes. I posted a new version of this patch set. I would be very grateful if
you could test it.

we tested this v11 version, and found the regression reduced to about 1.6%.
please be noted, according to our previous experience, the stress-ng is
kind of sensitive testsuite, so we normally wouldn't report <3% regression.
