gfs2: Fix lru_count going negative
Under certain conditions, lru_count may drop below zero resulting in
a large amount of log spam like this:
vmscan: shrink_slab: gfs2_dump_glock+0x3b0/0x630 [gfs2] \
negative objects to delete nr=-1
This happens as follows:
1) A glock is moved from lru_list to the dispose list and lru_count is
decremented.
2) The dispose function calls cond_resched() and drops the lru lock.
3) Another thread takes the lru lock and tries to add the same glock to
lru_list, checking if the glock is on an lru list.
4) It is on a list (actually the dispose list) and so it avoids
incrementing lru_count.
5) The glock is moved to lru_list.
5) The original thread doesn't dispose it because it has been re-added
to the lru list but the lru_count has still decreased by one.
Fix by checking if the LRU flag is set on the glock rather than checking
if the glock is on some list and rearrange the code so that the LRU flag
is added/removed precisely when the glock is added/removed from lru_list.

Fix the resource group wrap-around logic in gfs2_rbm_find that commit e579ed4f44 broke. The bug can lead to unnecessary repeated scanning of the
same bitmaps; there is a risk that future changes will turn this into an
endless loop.
This is an updated version of commit 2d29f6b96d ("gfs2: Fix loop in
gfs2_rbm_find") which ended up being reverted because it introduced a
performance regression in iozone (see commit e74c98ca2d). Changes since v1:
- Simplify the wrap-around logic.
- Handle the case where each resource group only has a single bitmap block
(small filesystem).
- Update rd_extfail_pt whenever we scan the entire bitmap, even when we don't
start the scan at the very beginning of the bitmap.

Pull pidfd updates from Christian Brauner:
"This patchset makes it possible to retrieve pidfds at process creation
time by introducing the new flag CLONE_PIDFD to the clone() system
call. Linus originally suggested to implement this as a new flag to
clone() instead of making it a separate system call.
After a thorough review from Oleg CLONE_PIDFD returns pidfds in the
parent_tidptr argument. This means we can give back the associated pid
and the pidfd at the same time. Access to process metadata information
thus becomes rather trivial.
As has been agreed, CLONE_PIDFD creates file descriptors based on
anonymous inodes similar to the new mount api. They are made
unconditional by this patchset as they are now needed by core kernel
code (vfs, pidfd) even more than they already were before (timerfd,
signalfd, io_uring, epoll etc.). The core patchset is rather small.
The bulky looking changelist is caused by David's very simple changes
to Kconfig to make anon inodes unconditional.
A pidfd comes with additional information in fdinfo if the kernel
supports procfs. The fdinfo file contains the pid of the process in
the callers pid namespace in the same format as the procfs status
file, i.e. "Pid:\t%d".
To remove worries about missing metadata access this patchset comes
with a sample/test program that illustrates how a combination of
CLONE_PIDFD and pidfd_send_signal() can be used to gain race-free
access to process metadata through /proc/<pid>.
Further work based on this patchset has been done by Joel. His work
makes pidfds pollable. It finished too late for this merge window. I
would prefer to have it sitting in linux-next for a while and send it
for inclusion during the 5.3 merge window"

this patch series is an attempt to fix the mess, I've somehow managed to

First patch in this series is defacto v5 of the previous 05/10 patch in the
series, but since the v4 of this 05/10 patch wasn't picked up by the
patchwork for some unknown reason, this patch wasn't applied with the other
9 patches in the series, so I'm resending it as a separate patch of this
fixup series again.
Second patch is a result of this rebase against net-next tree, where I was
checking again all current users of of_get_mac_address and found out, that
there's new one in DSA, so I've converted this user to the new ERR_PTR
encoded error value as well.
Third patch which was sent as v5 wasn't considered for merge, but I still
think, that we need to check for possible NULL value, thus current IS_ERR
check isn't sufficient and we need to use IS_ERR_OR_NULL instead.

FQ packet scheduler assumed that packets could be classified
based on their owning socket.
This means that if a UDP server uses one UDP socket to send
packets to different destinations, packets all land
in one FQ flow.
This is unfair, since each TCP flow has a unique bucket, meaning
that in case of pressure (fully utilised uplink), TCP flows
have more share of the bandwidth.
If we instead detect unconnected sockets, we can use a stochastic
hash based on the 4-tuple hash.
This also means a QUIC server using one UDP socket will properly
spread the outgoing packets to different buckets, and in-kernel
pacing based on EDT model will no longer risk having big rb-tree on
one flow.

"Here's a big pile of new stuff for XFS for 5.2. XFS has grown the
ability to report metadata health status to userspace after online
fsck checks the filesystem. The online metadata checking code is (I
really hope) feature complete with the addition of checks for the
global fs counters, though it'll remain EXPERIMENTAL for now.
There are also fixes for thundering herds of writeback completions and
some other deadlocks, fixes for theoretical integer overflow attacks
on space accounting, and removal of the long-defunct 'mntpt' option
which was deprecated in the mid-2000s and (it turns out) totally
broken since 2011 (and nobody complained...).
Summary:
- Fix some more buffer deadlocks when performing an unmount after a
hard shutdown.
- Fix some minor space accounting issues.
- Fix some use after free problems.
- Make the (undocumented) FITRIM behavior consistent with other
filesystems.
- Embiggen the xfs geometry ioctl's data structure.
- Introduce a new AG geometry ioctl.
- Introduce a new online health reporting infrastructure and ioctl
for userspace to query a filesystem's health status.
- Enhance online scrub and repair to update the health reports.
- Reduce thundering herd problems when writeback io completes.
- Fix some transaction reservation type errors.
- Fix integer overflow problems with delayed alloc reservation
counters.
- Fix some problems where we would exit to userspace without
unlocking.
- Fix inconsistent behavior when finishing deferred ops fails.
- Strengthen scrub to check incore data against ondisk metadata.
- Remove long-broken mntpt mount option.
- Add an online scrub function for the filesystem summary counters,

The VLAN aware bridge offloading is similar to the VLAN unaware
offloading, this makes it possible to offload the VLAN bridge
functionalities.
The hardware supports up to 64 VLAN bridge entries, we already use one
entry for each LAN port to prevent forwarding of packets between the
ports when the ports are not in a bridge, so in the end we have 57
possible VLANs.
The VLAN filtering is currently only active when the ports are in a
bridge, VLAN filtering for ports not in a bridge is not implemented.
It is currently not possible to change between VLAN filtering and not
filtering while the port is already in a bridge, this would make the
driver more complicated.
The VLANs are only defined on bridge entries, so we will not add
anything into the hardware when the port joins a bridge if it is doing
VLAN filtering, but only when an allowed VLAN is added.

This allows to offload bridges with DSA to the switch hardware and do
the packet forwarding in hardware.
This implements generic functions to access the switch hardware tables,
which are used to control many features of the switch.
This patch activates the MAC learning by removing the MAC address table
lock, to prevent uncontrolled forwarding of packets between all the LAN
ports, they are added into individual bridge tables entries with
individual flow ids and the switch will do the MAC learning for each
port separately before they are added to a real bridge.
Each bridge consist of an entry in the active VLAN table and the VLAN
mapping table, table entries with the same index are matching. In the
VLAN unaware mode we configure everything with VLAN ID 0, but we use
different flow IDs, the switch should handle all VLANs as normal payload
and ignore them. When the hardware looks for the port of the destination
MAC address it only takes the entries which have the same flow ID of the
ingress packet.
The bridges are configured with 64 possible entries with these
information:
Table Index, 0...63
VLAN ID, 0...4095: VLAN ID 0 is untagged
flow ID, 0..63: Same flow IDs share entries in MAC learning table

Whilst the sprintf in afs_xattr_get_fid() has been partially updated (it
currently ignores the upper 32 bits of the 96-bit vnode number), the size
of the stack-based buffer has not been increased to match, thereby allowing
stack corruption to occur.
Fix this by increasing the buffer size appropriately and conditionally

drm: Fix timestamp docs for variable refresh properties.
As discussed with Nicholas and Daniel Vetter (patchwork
link to discussion below), the VRR timestamping behaviour
produced utterly useless and bogus vblank/pageflip
timestamps. We have found a way to fix this and provide
sane behaviour.
As of Linux 5.2, the amdgpu driver will be able to
provide exactly the same vblank / pageflip timestamp
semantic in variable refresh rate mode as in standard
fixed refresh rate mode. This is achieved by deferring
core vblank handling (drm_crtc_handle_vblank()) until
the end of front porch, and also defer the sending of
pageflip completion events until end of front porch,
when we can safely compute correct pageflip/vblank
timestamps.
The same approach will be possible for other VRR
capable kms drivers, so we can actually have sane
and useful timestamps in VRR mode.
This patch removes the section of the docs that
describes the broken timestamp behaviour present
in Linux 5.0/5.1.

moduleparam: Save information about built-in modules in separate file
Problem:
When a kernel module is compiled as a separate module, some important
information about the kernel module is available via .modinfo section of
the module. In contrast, when the kernel module is compiled into the
kernel, that information is not available.
Information about built-in modules is necessary in the following cases:
1. When it is necessary to find out what additional parameters can be
passed to the kernel at boot time.
2. When you need to know which module names and their aliases are in
the kernel. This is very useful for creating an initrd image.
Proposal:
The proposed patch does not remove .modinfo section with module
information from the vmlinux at the build time and saves it into a
separate file after kernel linking. So, the kernel does not increase in
size and no additional information remains in it. Information is stored
in the same format as in the separate modules (null-terminated string
array). Because the .modinfo section is already exported with a separate
modules, we are not creating a new API.
It can be easily read in the userspace:

Remove MODULE_ALIAS() calls that take undefined macro
These files do not define (USBHS_)DRIVER_NAME. Yet, they can be
successfully compiled because they are never built as a module by
anyone, i.e, the MODULE_ALIAS() calls are always no-op.
A problem showed up when a patch "moduleparam: Save information about
built-in modules in separate file" was applied. With this new feature,
MODULE_*() will be populated even if the callers are built-in.
To avoid the build errors, the lines referencing to the undefined
macro must be removed.
The complete fix is to remove all MODULE_* and #include <linux/module.h>
like many "make ... explicitly non-modular" commits did.
For now, I am touching only the offending lines.

This is a sample program showing userspace how to get race-free access
to process metadata from a pidfd. It is rather easy to do and userspace
can actually simply reuse code that currently parses a process's status
file in procfs.
The program can easily be extended into a generic helper suitable for
inclusion in a libc to make it even easier for userspace to gain metadata
access.
Since this came up in a discussion because this API is going to be used
in various service managers: A lot of programs will have a whitelist
seccomp filter that returns <some-errno> for all new syscalls. This
means that programs might get confused if CLONE_PIDFD works but the
later pidfd_send_signal() syscall doesn't. Hence, here's a ahead of
time check that pidfd_send_signal() is supported:
bool pidfd_send_signal_supported()
{
int procfd = open("/proc/self", O_DIRECTORY | O_RDONLY | O_CLOEXEC);
if (procfd < 0)
return false;
/*
* A process is always allowed to signal itself so
* pidfd_send_signal() should never fail this test. If it does
* it must mean it is not available, blocked by an LSM, seccomp,
* or other.
*/
return pidfd_send_signal(procfd, 0, NULL, 0) == 0;
}

signal: support CLONE_PIDFD with pidfd_send_signal
Let pidfd_send_signal() use pidfds retrieved via CLONE_PIDFD. With this
patch pidfd_send_signal() becomes independent of procfs. This fullfils
the request made when we merged the pidfd_send_signal() patchset. The
pidfd_send_signal() syscall is now always available allowing for it to
be used by users without procfs mounted or even users without procfs
support compiled into the kernel.

This patchset makes it possible to retrieve pid file descriptors at
process creation time by introducing the new flag CLONE_PIDFD to the
clone() system call. Linus originally suggested to implement this as a
new flag to clone() instead of making it a separate system call. As
spotted by Linus, there is exactly one bit for clone() left.
CLONE_PIDFD creates file descriptors based on the anonymous inode
implementation in the kernel that will also be used to implement the new
mount api. They serve as a simple opaque handle on pids. Logically,
this makes it possible to interpret a pidfd differently, narrowing or
widening the scope of various operations (e.g. signal sending). Thus, a
pidfd cannot just refer to a tgid, but also a tid, or in theory - given
appropriate flag arguments in relevant syscalls - a process group or
session. A pidfd does not represent a privilege. This does not imply it
cannot ever be that way but for now this is not the case.
A pidfd comes with additional information in fdinfo if the kernel supports
procfs. The fdinfo file contains the pid of the process in the callers
pid namespace in the same format as the procfs status file, i.e. "Pid:\t%d".
As suggested by Oleg, with CLONE_PIDFD the pidfd is returned in the
parent_tidptr argument of clone. This has the advantage that we can
give back the associated pid and the pidfd at the same time.
To remove worries about missing metadata access this patchset comes with
a sample program that illustrates how a combination of CLONE_PIDFD, and
pidfd_send_signal() can be used to gain race-free access to process
metadata through /proc/<pid>. The sample program can easily be
translated into a helper that would be suitable for inclusion in libc so
that users don't have to worry about writing it themselves.

Pull ACPI updates from Rafael Wysocki:
"These rearrange the ACPI documentation by converting it to the .rst
format and splitting it into clear categories (admin guide, driver
API, firmware guide), switch over multiple users of a problematic
library function to a new better one, update the ACPICA code in the
kernel to a new upstream release, fix a few issues, improve power
device management diagnostics and do some cleanups.
Specifics:
- Convert the ACPI documentation in the kernel source tree to the
.rst format and split it into the admin guide, driver API and
firmware guide parts (Changbin Du).
- Add a PRP0001 usage example to the ACPI documentation (Thomas
Preston).
- Switch over the users of the acpi_dev_get_first_match_name()
library function which turned out to be problematic to a new,
better one called acpi_dev_get_first_match_dev() (Andy Shevchenko,
YueHaibing).
- Update the ACPICA code in the kernel to upstream release 20190405
including:
* Null pointer dereference check in acpi_ns_delete_node() (Erik
Schmauss).
* Multiple macro and function name changes (Bob Moore).
* Predefined operation region name fix (Erik Schmauss).
- Fix hibernation issue on systems using the Baytrail and Cherrytrail
Intel SoCs introduced during the 4.20 development cycle (Hans de
Goede).
- Add Sony VPCEH3U1E to the backlight quirk list (Zhang Rui).
- Fix button handling during system resume (Zhang Rui).
- Add a device PM diagnostic message (Rafael Wysocki).
- Clean up the code, comments and white space in multiple places
(Bjorn Helgaas, Gustavo Silva, Kefeng Wang)"
