Merge series "Extend regulator notification support" from Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com>:

Extend regulator notification support

This series extends the regulator notification and error flag support.
Initial discussion on the topic can be found here:
https://lore.kernel.org/lkml/6046836e22b8252983f08d5621c35ececb97820d.camel@fi.rohmeurope.com/

In a nutshell - the series adds:

1. WARNING level events/error flags. (Patch 3)
Current regulator 'ERROR' event notifications for over/under
voltage, over current and over temperature are used to indicate
condition where monitored entity is so badly "off" that it actually
indicates a hardware error which can not be recovered. The most
typical hanling for that is believed to be a (graceful)
system-shutdown. Here we add set of 'WARNING' level flags to allow
sending notifications to consumers before things are 'that badly off'
so that consumer drivers can implement recovery-actions.
2. Device-tree properties for specifying limit values. (Patches 1, 5)
Add limits for above mentioned 'ERROR' and 'WARNING' levels (which
send notifications to consumers) and also for a 'PROTECTION' level
(which will be used to immediately shut-down the regulator(s) W/O
informing consumer drivers. Typically implemented by hardware).
Property parsing is implemented in regulator core which then calls
callback operations for limit setting from the IC drivers. A
warning is emitted if protection is requested by device tree but the
underlying IC does not support configuring requested protection.
3. Helpers which can be registered by IC. (Patch 4)
Target is to avoid implementing IRQ handling and IRQ storm protection
in each IC driver. (Many of the ICs implementin these IRQs do not allow
masking or acking the IRQ but keep the IRQ asserted for the whole
duration of problem keeping the processor in IRQ handling loop).
4. Emergency poweroff function (refactored out of the thermal_core to
kernel/reboot.c) which is called if IC fires error IRQs but IC reading
fails and given retry-count is exceeded. (Patches 2, 4)
Please note that the mutex in the emergency shutdown was replaced by a
simple atomic in order to allow call from any context.

The helper was attempted to be done so it could be used to implement
roughly same logic as is used in qcom-labibb regulator. This means
amongst other things a safety shut-down if IC registers are not readable.
Using these shut-down retry counters are optional. The idea is that the
helper could be also used by simpler ICs which do not provide status
register(s) which can be used to check if error is still active.

ICs which do not have such status register can simply omit the 'renable'
callback (and retry-counts etc) - and helper assumes the situation is Ok
and re-enables IRQ after given time period. If problem persists the
handler is ran again and another notification is sent - but at least the
delay allows processor to avoid IRQ loop.

Patch 7 takes this notification support in use at BD9576MUF.
Patch 8 is related to MFD change which is not really related to the RFC
here. It was added to this series in order to avoid potential conflicts.
Patch 9 adds a maintainers entry.

Changelog v10-RESEND:
- rebased on v5.13-rc4
Changelog v10:
- rebased on v5.13-rc2
- Move rdev_*() print macros to the internal.h and use rdev_dbg()
from irq_helpers.c
- Export rdev_get_name() and move it from coupler.h to driver.h for
others to use. (It was already in coupler.h but not exported -
usage was limited and coupler.h does not sound like optimal place
as rdev_name is not only used by coupled regulators)
- Send all regulator notifications from irq_helpers.c at one OR'd
event for the sake of simplicity. For BD9576 this does not matter
as it has own IRQ for each event case. Header defining events says
they may be OR'd.
- Change WARN() at protection shutdown to pr_emerg as suggested by
Petr.
Changelog v9:
- rebases on v5.13-rc1
- Update thermal documentation
- Fix regulator notification event number

are only allowed to coexist with capable devices

- stmmac:
- fix kernel panic due to NULL pointer dereference of
mdio_bus_data
- fix double clk unprepare when no PHY device is connected

Current release - new code bugs:

- mt76: a few fixes for the recent MT7921 devices and runtime power
management

Previous releases - regressions:

- ice:
- track AF_XDP ZC enabled queues in bitmap to fix copy mode Tx
- fix allowing VF to request more/less queues via virtchnl
- correct supported and advertised autoneg by using PHY
capabilities
- allow all LLDP packets from PF to Tx

- kbuild: quote OBJCOPY var to avoid a pahole call break the build

Previous releases - always broken:

- bpf, lockdown, audit: fix buggy SELinux lockdown permission checks

- mt76: address the recent FragAttack vulnerabilities not covered by
generic fixes

- ipv6: fix KASAN: slab-out-of-bounds Read in
fib6_nh_flush_exceptions

- Bluetooth:
- fix the erroneous flush_work() order, to avoid double free
- use correct lock to prevent UAF of hdev object

- nfc: fix NULL ptr dereference in llcp_sock_getname() after failed
connect

- ieee802154: multiple fixes to error checking and return values

- igb: fix XDP with PTP enabled

- intel: add correct exception tracing for XDP

- tls: fix use-after-free when TLS offload device goes down and back
up

- ipvs: ignore IP_VS_SVC_F_HASHED flag when adding service

- netfilter: nft_ct: skip expectations for confirmed conntrack

- mptcp: fix falling back to TCP in presence of out of order packets
early in connection lifetime

- wireguard: switch from O(n) to a O(1) algorithm for maintaining
peers, fixing stalls and a large memory leak in the process

Misc:

- devlink: correct VIRTUAL port to not have phys_port attributes

- Bluetooth: fix VIRTIO_ID_BT assigned number

- net: return the correct errno code ENOBUF -> ENOMEM

- wireguard:
- peer: allocate in kmem_cache saving 25% on peer memory

bpf, lockdown, audit: Fix buggy SELinux lockdown permission checks

Commit 59438b46471a ("security,lockdown,selinux: implement SELinux lockdown")
added an implementation of the locked_down LSM hook to SELinux, with the aim
to restrict which domains are allowed to perform operations that would breach
lockdown. This is indirectly also getting audit subsystem involved to report
events. The latter is problematic, as reported by Ondrej and Serhei, since it
can bring down the whole system via audit:

1) The audit events that are triggered due to calls to security_locked_down()
can OOM kill a machine, see below details [0].

2) It also seems to be causing a deadlock via avc_has_perm()/slow_avc_audit()
when trying to wake up kauditd, for example, when using trace_sched_switch()
tracepoint, see details in [1]. Triggering this was not via some hypothetical
corner case, but with existing tools like runqlat & runqslower from bcc, for
example, which make use of this tracepoint. Rough call sequence goes like:

rq_lock(rq) -> -------------------------+
trace_sched_switch() -> |
bpf_prog_xyz() -> +-> deadlock
selinux_lockdown() -> |
audit_log_end() -> |
wake_up_interruptible() -> |
try_to_wake_up() -> |
rq_lock(rq) --------------+

What's worse is that the intention of 59438b46471a to further restrict lockdown
settings for specific applications in respect to the global lockdown policy is
completely broken for BPF. The SELinux policy rule for the current lockdown check
looks something like this:

allow <who> <who> : lockdown { <reason> };

However, this doesn't match with the 'current' task where the security_locked_down()
is executed, example: httpd does a syscall. There is a tracing program attached
to the syscall which triggers a BPF program to run, which ends up doing a
bpf_probe_read_kernel{,_str}() helper call. The selinux_lockdown() hook does
the permission check against 'current', that is, httpd in this example. httpd
has literally zero relation to this tracing program, and it would be nonsensical
having to write an SELinux policy rule against httpd to let the tracing helper
pass. The policy in this case needs to be against the entity that is installing
the BPF program. For example, if bpftrace would generate a histogram of syscall
counts by user space application:

bpftrace -e 'tracepoint:raw_syscalls:sys_enter { @[comm] = count(); }'

bpftrace would then go and generate a BPF program from this internally. One way
of doing it [for the sake of the example] could be to call bpf_get_current_task()
helper and then access current->comm via one of bpf_probe_read_kernel{,_str}()
helpers. So the program itself has nothing to do with httpd or any other random
app doing a syscall here. The BPF program _explicitly initiated_ the lockdown
check. The allow/deny policy belongs in the context of bpftrace: meaning, you
want to grant bpftrace access to use these helpers, but other tracers on the
system like my_random_tracer _not_.

Therefore fix all three issues at the same time by taking a completely different
approach for the security_locked_down() hook, that is, move the check into the
program verification phase where we actually retrieve the BPF func proto. This
also reliably gets the task (current) that is trying to install the BPF tracing
program, e.g. bpftrace/bcc/perf/systemtap/etc, and it also fixes the OOM since
we're moving this out of the BPF helper's fast-path which can be called several
millions of times per second.

The check is then also in line with other security_locked_down() hooks in the
system where the enforcement is performed at open/load time, for example,
open_kcore() for /proc/kcore access or module_sig_check() for module signatures
just to pick few random ones. What's out of scope in the fix as well as in
other security_locked_down() hook locations /outside/ of BPF subsystem is that
if the lockdown policy changes on the fly there is no retrospective action.
This requires a different discussion, potentially complex infrastructure, and
it's also not clear whether this can be solved generically. Either way, it is
out of scope for a suitable stable fix which this one is targeting. Note that
the breakage is specifically on 59438b46471a where it started to rely on 'current'
as UAPI behavior, and _not_ earlier infrastructure such as 9d1f8be5cf42 ("bpf:
Restrict bpf when kernel lockdown is in confidentiality mode").

[0] https://bugzilla.redhat.com/show_bug.cgi?id=1955585, Jakub Hrozek says:

I starting seeing this with F-34. When I run a container that is traced with
BPF to record the syscalls it is doing, auditd is flooded with messages like:

type=AVC msg=audit(1619784520.593:282387): avc: denied { confidentiality }
for pid=476 comm="auditd" lockdown_reason="use of bpf to read kernel RAM"
scontext=system_u:system_r:auditd_t:s0 tcontext=system_u:system_r:auditd_t:s0
tclass=lockdown permissive=0

This seems to be leading to auditd running out of space in the backlog buffer
and eventually OOMs the machine.
