When the ucount code was refactored to create get_ucount it was missed
that some of the contexts in which a rlimit is kept elevated can be
the only reference to the user/ucount in the system.
Ordinary ucount references exist in places that also have a reference
to the user namspace, but in POSIX message queues, the SysV shm code,
and the SIGPENDING code there is no independent user namespace
reference.
Inspection of the the user_namespace show no instance of circular
references between struct ucounts and the user_namespace. So
hold a reference from struct ucount to i's user_namespace to
resolve this problem.

The ->percpu_enqueue_shift field is used to map from the running CPU
number to the index of the corresponding callback list. This mapping
can change at runtime in response to varying callback load, resulting
in varying levels of contention on the callback-list locks.
Unfortunately, the initial value of this field is correct only if the
system happens to have a power-of-two number of CPUs, otherwise the
callbacks from the high-numbered CPUs can be placed into the callback list
indexed by 1 (rather than 0), and those index-1 callbacks will be ignored.
This can result in soft lockups and hangs.
This commit therefore corrects this mapping, adding one to this shift
count as needed for systems having odd numbers of CPUs.

The active cgroup events are managed in the per-cpu cgrp_cpuctx_list.
This list is only accessed from current cpu and not protected by any
locks. But from the commit ef54c1a476ae ("perf: Rework
perf_event_exit_event()"), it's possible to access (actually modify)
the list from another cpu.
In the perf_remove_from_context(), it can remove an event from the
context without an IPI when the context is not active. This is not
safe with cgroup events which can have some active events in the
context even if ctx->is_active is 0 at the moment. The target cpu
might be in the middle of list iteration at the same time.
If the event is enabled when it's about to be closed, it might call
perf_cgroup_event_disable() and list_del() with the cgrp_cpuctx_list
on a different cpu.
This resulted in a crash due to an invalid list pointer access during
the cgroup list traversal on the cpu which the event belongs to.
Let's fallback to IPI to access the cgrp_cpuctx_list from that cpu.
Similarly, perf_install_in_context() should use IPI for the cgroup
events too.

When using per-process mode and event inheritance is set to true,
forked processes will create a new perf events via inherit_event() ->
perf_event_alloc(). But these events will not have ring buffers
assigned to them. Any call to wakeup will be dropped if it's called on
an event with no ring buffer assigned because that's the object that
holds the wakeup list.
If the child event is disabled due to a call to
perf_aux_output_begin() or perf_aux_output_end(), the wakeup is
dropped leaving userspace hanging forever on the poll.
Normally the event is explicitly re-enabled by userspace after it
wakes up to read the aux data, but in this case it does not get woken
up so the event remains disabled.
This can be reproduced when using Arm SPE and 'stress' which forks once
before running the workload. By looking at the list of aux buffers read,
it's apparent that they stop after the fork:
perf record -e arm_spe// -vvv -- stress -c 1
With this patch applied they continue to be printed. This behaviour
doesn't happen when using systemwide or per-cpu mode.

The membarrier command MEMBARRIER_CMD_QUERY allows querying the
available membarrier commands. When the membarrier-rseq fence commands
were added, a new MEMBARRIER_CMD_PRIVATE_EXPEDITED_RSEQ_BITMASK was
introduced with the intent to expose them with the MEMBARRIER_CMD_QUERY
command, the but it was never added to MEMBARRIER_CMD_BITMASK.
The membarrier-rseq fence commands are therefore not wired up with the
query command.
Rename MEMBARRIER_CMD_PRIVATE_EXPEDITED_RSEQ_BITMASK to
MEMBARRIER_PRIVATE_EXPEDITED_RSEQ_BITMASK (the bitmask is not a command
per-se), and change the erroneous
MEMBARRIER_CMD_REGISTER_PRIVATE_EXPEDITED_RSEQ_BITMASK (which does not
actually exist) to MEMBARRIER_CMD_REGISTER_PRIVATE_EXPEDITED_RSEQ.
Wire up MEMBARRIER_PRIVATE_EXPEDITED_RSEQ_BITMASK in
MEMBARRIER_CMD_BITMASK. Fixing this allows discovering availability of
the membarrier-rseq fence feature.

When an admin enables audit at early boot via the "audit=1" kernel
command line the audit queue behavior is slightly different; the
audit subsystem goes to greater lengths to avoid dropping records,
which unfortunately can result in problems when the audit daemon is
forcibly stopped for an extended period of time.
This patch makes a number of changes designed to improve the audit
queuing behavior so that leaving the audit daemon in a stopped state
for an extended period does not cause a significant impact to the
system.
- kauditd_send_queue() is now limited to looping through the
passed queue only once per call. This not only prevents the
function from looping indefinitely when records are returned
to the current queue, it also allows any recovery handling in
kauditd_thread() to take place when kauditd_send_queue()
returns.
- Transient netlink send errors seen as -EAGAIN now cause the
record to be returned to the retry queue instead of going to
the hold queue. The intention of the hold queue is to store,
perhaps for an extended period of time, the events which led
up to the audit daemon going offline. The retry queue remains
a temporary queue intended to protect against transient issues
between the kernel and the audit daemon.
- The retry queue is now limited by the audit_backlog_limit
setting, the same as the other queues. This allows admins
to bound the size of all of the audit queues on the system.
- kauditd_rehold_skb() now returns records to the end of the
hold queue to ensure ordering is preserved in the face of
recent changes to kauditd_send_queue().

Pull ftrace fix from Steven Rostedt:
"Fix s390 breakage from sorting mcount tables.
The latest merge of the tracing tree sorts the mcount table at build
time. But s390 appears to do things differently (like always) and
replaces the sorted table back to the original unsorted one. As the
ftrace algorithm depends on it being sorted, bad things happen when it
is not, and s390 experienced those bad things.
Add a new config to tell the boot if the mcount table is sorted or
not, and allow s390 to opt out of it"

ftrace: Fix assuming build time sort works for s390
|
|
To speed up the boot process, as mcount_loc needs to be sorted for ftrace
to work properly, sorting it at build time is more efficient than boot up
and can save milliseconds of time. Unfortunately, this change broke s390
as it will modify the mcount_loc location after the sorting takes place
and will put back the unsorted locations. Since the sorting is skipped at
boot up if it is believed that it was sorted at run time, ftrace can crash
as its algorithms are dependent on the list being sorted.
Add a new config BUILDTIME_MCOUNT_SORT that is set when
BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine
if sorting should take place at boot up.

This moves the namespace sysctls to its own file as part of the
kernel/sysctl.c spring cleaning
Since we have now removed all sysctls for "fs", we now have to declare
it on the filesystem code, we do that using the new helper, which
reduces boiler plate code.
We rename init_fs_shared_sysctls() to init_fs_sysctls() to reflect that
now fs/sysctls.c is taking on the burden of being the first to register
the base directory as well.
Lastly, since init code will load in the order in which we link it we
have to move the sysctl code to be linked in early, so that its early
init routine runs prior to other fs code. This way, other filesystem
code can register their own sysctls using the helpers after this:
* register_sysctl_init()
* register_sysctl()

Patch series "sysctl: add and use base directory declarer and
registration helper".
In this patch series we start addressing base directories, and so we
start with the "fs" sysctls. The end goal is we end up completely
moving all "fs" sysctl knobs out from kernel/sysctl.
This patch (of 6):
Add a set of helpers which can be used to declare and register base
directory sysctls on their own. We do this so we can later move each of
the base sysctl directories like "fs", "kernel", etc, to their own
respective files instead of shoving the declarations and registrations
all on kernel/sysctl.c. The lazy approach has caught up and with this,
we just end up extending the list of base directories / sysctls on one
file and this makes maintenance difficult due to merge conflicts from
many developers.
The declarations are used first by kernel/sysctl.c for registration its
own base which over time we'll try to clean up. It will be used in the
next patch to demonstrate how to cleanly deal with base sysctl
directories.

kernel/sysctl.c is a kitchen sink where everyone leaves their dirty
dishes, this makes it very difficult to maintain.
To help with this maintenance let's start by moving sysctls to places
where they actually belong. The proc sysctl maintainers do not want to
know what sysctl knobs you wish to add for your own piece of code, we
just care about the core logic.
So move the pipe sysctls to its own file.

Since checkpatch complains about style issues with the old code, this
move also fixes a few of those minor style issues:
* Use pr_warn() instead of prink(WARNING
* New empty lines are wanted at the beginning of routines

Other than the move we also avoid initializing two static variables to 0
as this is not needed:

small one-off entry, perhaps later we can simplify this representation,
but for now we use the helpers we have. We won't know how we can
simplify this further untl we're fully done with the cleanup.

Patch series "sysctl: 4th set of kernel/sysctl cleanups".
This is slimming down the fs uses of kernel/sysctl.c to the point that
the next step is to just get rid of the fs base directory for it and
move that elsehwere, so that next patch series starts dealing with that
to demo how we can end up cleaning up a full base directory from
kernel/sysctl.c, one at a time.
This patch (of 9):
kernel/sysctl.c is a kitchen sink where everyone leaves their dirty
dishes, this makes it very difficult to maintain.
To help with this maintenance let's start by moving sysctls to places
where they actually belong. The proc sysctl maintainers do not want to

this outside of fs/ remove the extern declaration of its respective proc
helper.
We use early_initcall() as it is the earliest we can use.

Patch series "sysctl: 3rd set of kernel/sysctl cleanups", v2.
This is the third set of patches to help address cleaning the kitchen
seink in kernel/sysctl.c and to move sysctls away to where they are
actually implemented / used.
This patch (of 8):
kernel/sysctl.c is a kitchen sink where everyone leaves their dirty
dishes, this makes it very difficult to maintain.
To help with this maintenance let's start by moving sysctls to places
where they actually belong. The proc sysctl maintainers do not want to

So move the firmware configuration sysctl table to the only place where
it is used, and make it clear that if sysctls are disabled this is not
used.

The kernel/sysctl.c is a kitchen sink where everyone leaves their dirty
dishes, this makes it very difficult to maintain.
To help with this maintenance let's start by moving sysctls to places
where they actually belong. The proc sysctl maintainers do not want to
know what sysctl knobs you wish to add for your own piece of code, we
just care about the core logic.
So move the epoll_table sysctl to fs/eventpoll.c and use
register_sysctl().

There is no need to user boiler plate code to specify a set of base
directories we're going to stuff sysctls under. Simplify this by using
register_sysctl() and specifying the directory path directly.
Move inotify_user sysctl to inotify_user.c while at it to remove clutter
from kernel/sysctl.c.

When proc_dointvec_minmax() or proc_doulongvec_minmax() are used we are
using the extra1 and extra2 parameters on the sysctl table only for a
min and max boundary, these extra1 and extra2 arguments are then used
for read-only operations. So make them const to reflect this.
