O-Subject: [RHEL8 BZ1518076 PATCH] ACPI: APEI: arm64: Ignore broken HPE moonshot APEI support

Brew: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=15417197
Tested: compile-only; several other patches are required for full booting
QE has tested limited boot (see comment#12 of BZ)
This is a re-post of a RHEL-ALT-7.5 patch specific to aarch64 moonshots
that we use in beaker. It is required for these machines to boot.

[acpi] APEI: arm64: Ignore broken HPE moonshot APEI support
From: Mark Salter <msalter@redhat.com>
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1344237
Brew: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=13768971
Tested: Booted on moonshot with patched 4.11.0-20 kernel
Upstream: RHEL-only
The aarch64 HP moonshot platforms we have in beaker and elsewhere have
a firmware bug which causes a spurious fatal memory error via APEI at
boot time. This platform is no longer supported and no further firmware
updates are expected. This is a downstream-only hack to avoid the problem
by bailing out of HEST table probing if we detect a moonshot HEST table.

The ACPI firmware on the xgene-based m400 platorms erroneously
describes its UART interrupt as ACPI_PRODUCER rather than
ACPI_CONSUMER. This leads to the UART driver being unable to
find its interrupt and the kernel unable find a console.
Work around this by avoiding the producer/consumer check
for X-Gene UARTs.

Subject: [PATCH] ARM: fix __get_user_check() in case uaccess_* calls are not
inlined
KernelCI reports that bcm2835_defconfig is no longer booting since
commit ac7c3e4ff401 ("compiler: enable CONFIG_OPTIMIZE_INLINING
forcibly"):
https://lkml.org/lkml/2019/9/26/825
I also received a regression report from Nicolas Saenz Julienne:
https://lkml.org/lkml/2019/9/27/263
This problem has cropped up on arch/arm/config/bcm2835_defconfig
because it enables CONFIG_CC_OPTIMIZE_FOR_SIZE. The compiler tends
to prefer not inlining functions with -Os. I was able to reproduce
it with other boards and defconfig files by manually enabling
CONFIG_CC_OPTIMIZE_FOR_SIZE.
The __get_user_check() specifically uses r0, r1, r2 registers.
So, uaccess_save_and_enable() and uaccess_restore() must be inlined
in order to avoid those registers being overwritten in the callees.
Prior to commit 9012d011660e ("compiler: allow all arches to enable
CONFIG_OPTIMIZE_INLINING"), the 'inline' marker was always enough for
inlining functions, except on x86.
Since that commit, all architectures can enable CONFIG_OPTIMIZE_INLINING.
So, __always_inline is now the only guaranteed way of forcible inlining.
I want to keep as much compiler's freedom as possible about the inlining
decision. So, I changed the function call order instead of adding
__always_inline around.
Call uaccess_save_and_enable() before assigning the __p ("r0"), and
uaccess_restore() after evacuating the __e ("r0").
Fixes: 9012d011660e ("compiler: allow all arches to enable CONFIG_OPTIMIZE_INLINING")

Subject: [PATCH] Add option of 13 for FORCE_MAX_ZONEORDER
This is a hack, but it's what the other distros currently use
for aarch64 with 4K pages so we'll do the same while upstream
decides what the best outcome is (which isn't this).

Subject: [PATCH] Input: rmi4 - remove the need for artificial IRQ in case of
HID
The IRQ from rmi4 may interfere with the one we currently use on i2c-hid.
Given that there is already a need for an external API from rmi4 to
forward the attention data, we can, in this particular case rely on a
separate workqueue to prevent cursor jumps.

Subject: [PATCH] KEYS: Make use of platform keyring for module signature
verify
This patch completes commit 278311e417be ("kexec, KEYS: Make use of
platform keyring for signature verify") which, while adding the
platform keyring for bzImage verification, neglected to also add
this keyring for module verification.
As such, kernel modules signed with keys from the MokList variable
were not successfully verified.

starting from 160 instead of 0. A different approach is taken to avoid this
abnormal way of enabling ECAM for just one controller but to enable
configuration space access for all the other controllers. In this approach,
ops are added through MCFG quirk mechanism which access the configuration
spaces by dynamically programming iATU (internal AddressTranslation Unit)
to generate respective configuration accesses just like the way it is
done in DesignWare core sub-system.

PCI BAR 5 is not setup correctly for the on-board AHCI
controller on Broadcom's Vulcan processor. Added a quirk to fix BAR 5
by using BAR 4's resources which are populated correctly but NOT used
by the AHCI controller actually.
RHEL-only:
Both patches are in RHEL-7.6 also. Inclusion of the patches into RHEL-8
was discussed. Since there are partners with Ax system configurations it
was decided to carry them in RHEL8 too. See:

Message-id: <20180510173844.29580-4-msalter@redhat.com>
Patchwork-id: 214381
O-Subject: [RHEL-8 BZ1519554 3/3] aarch64: acpi scan: Fix regression related to X-Gene UARTs
Bugzilla: 1519554
RH-Acked-by: Al Stone <astone@redhat.com>

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1519554
Brew: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=16144520
Commit e361d1f85855 ("ACPI / scan: Fix enumeration for special UART
devices") caused a regression with some X-Gene based platforms (Mustang
and M400) with invalid DSDT. The DSDT makes it appear that the UART
device is also a slave device attached to itself. With the above commit
the UART won't be enumerated by ACPI scan (slave serial devices shouldn't
be). So check for X-Gene UART device and skip slace device check on it.

Apply workaround for this errata:
Synopsis: Resetting PxCMD.ST may hang the SATA device
Description: An internal ping-pong buffer state is not reset
correctly for an PxCMD.ST=0 command for a SATA channel. This
may cause the SATA interface to hang when a PxCMD.ST=0 command
is received.
Workaround: A SATA_BIU_CORE_ENABLE.sw_init_bsi must be asserted
by the driver whenever the PxCMD.ST needs to be de-asserted. This
will reset both the ports. So, it may not always work in a 2
channel SATA system.
Resolution: Fix in B0.
Add the code to ahci_stop_engine() to do this. It is not easy to
stop the other "port" since it is associated with a different AHCI
interface. Please note that with this fix, SATA reset does not
hang any more, but it can cause failures on the other interface
if that is in active use.
Unfortunately, we have nothing other the the CPU ID to check if the
SATA block has this issue.
RHEL-only:
Both patches are in RHEL-7.6 also. Inclusion of the patches into RHEL-8
was discussed. Since there are partners with Ax system configurations it
was decided to carry them in RHEL8 too. See:

Bugzilla:

We don't turn on EXPERT as there are few settings we actually want to
mess with. Remove the dependency for ARM64_FORCE_52BIT as we do want
that on in debug builds to help find 52-bit bugs.

From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001
From: Ondrej Jirman <megous@megous.com>
Date: Fri, 26 Jun 2020 02:55:52 +0200
Subject: [PATCH] drm/panel: rocktech-jh057n00900: Rename the driver to st7703
This rename is done so that the driver matches the name of the
display controller and in preparation for adding support for more
panels to the driver.
This is just a basic file rename, with no code changes.

Subject: [PATCH] drm/panel: st7703: Assert reset prior to powering down the
regulators
The reset pin is inverted, so if we don't assert reset, the actual gpio
will be high and may keep driving the IO port of the panel.

Subject: [PATCH] drm/panel: st7703: Rename functions from jh057n prefix to

This is done so that code that's not specific to a particular
jh057n panel is named after the controller. Functions specific
to the panel are kept named after the panel.

Subject: [PATCH] drm/sun4i: sun6i_mipi_dsi: fix horizontal timing calculation
The max() function call in horizontal timing calculation shouldn't pad a
length already subtracted with overhead to overhead, instead it should
only prevent the set timing to underflow.

UEFI machines can be booted in Secure Boot mode. Add an EFI_SECURE_BOOT

Move the switch-statement in x86's setup_arch() that inteprets the
secure_boot boot parameter to generic code and set the bit there.

Subject: [PATCH] efi: Lock down the kernel if booted in secure boot mode
UEFI Secure Boot provides a mechanism for ensuring that the firmware
will only load signed bootloaders and kernels. Certain use cases may
also require that all kernel modules also be signed. Add a
configuration option that to lock down the kernel - which includes
requiring validly signed modules - if the kernel is secure-booted.

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1624077
Brew: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=18112820
Testing: Verified iommu.passthrough=1 no longer needed on gigabyte platforms.
Upstream Status: RHEL-only
In RHEL_ALT 7.5 we carried a RHEL-only patch which forced the arm smmuv2
into bypass mode due to performance issues on CN88xx. This was intended
to be a temporary hack until the issues were resolved. Another vendor
had issues with the iommu in bypass mode so we reverted the RHEL-only
patch so that iommu is in DMA mode by default (upstream default).
It turns on that there are remaining SMMU DMA mode issues on Gigabyte
platformws with CN88xx cpus. The problem manifests itself by pcie
card drivers failing to initialize the cards when SMMU is in DMA mode.
The root cause has not been determined yet, but looks likely to be
a hw or firmware issue. This patch forces bypass mode for Gigabyte
platforms. CN88xx isn't officially supported in RHEL but we have a
lot of them being used internally for testing, so I think we want
this to support that use case in RHEL8.

RHEL-only
The ARM-based HPE m400 reports host-side ipmi as residing in intel
port-io space, which does not exist in ARM processors. Therefore, when
running on an m400, host-side ipmi configuration code must simply return
zero without trying to configure the host-side ipmi.
This patch prevents panic on boot by averting attempts to configure
host-side ipmi on this platform.
Though HPE m400 is not certified with RHEL, and HPE has relegated it to
EOL status, the platform is still used extensively in ARM development
and test for RHEL.
Testing:
Boot without blacklisting ipmi and check to see that no ipmi modules
are loaded.

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1507353
Build: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=16534135
Tested: ppc64le, x86_64 with several memory sizes.
kdump qe tested 160M on various x86 machines in lab.
We continue to provide crashkernel=auto like we did in RHEL6
and RHEL7, this will simplify the kdump deployment for common
use cases that kdump just works with the auto reserved values.
But this is still a best effort estimation, we can not know the
exact memory requirement because it depends on a lot of different
factors.
The implementation of crashkernel=auto is simplified as a wrapper
to use below kernel cmdline:
x86_64: crashkernel=1G-64G:160M,64G-1T:256M,1T-:512M
s390x: crashkernel=4G-64G:160M,64G-1T:256M,1T-:512M
arm64: crashkernel=2G-:512M
ppc64: crashkernel=2G-4G:384M,4G-16G:512M,16G-64G:1G,64G-128G:2G,128G-:4G
The difference between this way and the old implementation in
RHEL6/7 is we do not scale the crash reserved memory size according
to system memory size anymore.
Latest effort to move upstream is below thread:
https://lkml.org/lkml/2018/5/20/262
But unfortunately it is still unlikely to be accepted, thus we
will still use a RHEL only patch in RHEL8.
Copied old patch description about the history reason see below:
'''
Non-upstream explanations:
Besides "crashkenrel=X@Y" format, upstream also has advanced
"crashkernel=range1:size1[,range2:size2,...][@offset]", and
"crashkernel=X,high{low}" formats, but they need more careful
manual configuration, and have different values for different
architectures.
Most of the distributions use the standard "crashkernel=X@Y"
upstream format, and use crashkernel range format for advanced
scenarios, heavily relying on the user's involvement.
While "crashkernel=auto" is redhat's special feature, it exists
and has been used as the default boot cmdline since 2008 rhel6.
It does not require users to figure out how many crash memory
size for their systems, also has been proved to be able to work
pretty well for common scenarios.
"crashkernel=auto" was tested/based on rhel-related products, as
we have stable kernel configurations which means more or less
stable memory consumption. In 2014 we tried to post them again to
upstream but NACKed by people because they think it's not general
and unnecessary, users can specify their own values or do that by
scripts. However our customers insist on having it added to rhel.
Also see one previous discussion related to this backport to Pegas:

We had proposed to drop the historic crashkernel=auto code and move
to use crashkernel=range:size format and pass them in anaconda.
The initial reason is crashkernel=range:size works just fine because
we do not need complex algorithm to scale crashkernel reserved size
any more. The old linear scaling is mainly for old makedumpfile
requirements, now it is not necessary.
But With the new approach, backward compatibility is potentially at risk.
For e.g. let's consider the following cases:
1) When we upgrade from an older distribution like rhel-alt-7.4(which
uses crashkernel=auto) to rhel-alt-7.5 (which uses the crashkernel=xY
format)
In this case we can use anaconda scripts for checking
'crashkernel=auto' in kernel spec and update to the new
'crashkernel=range:size' format.
2) When we upgrade from rhel-alt-7.5(which uses crashkernel=xY format)
to rhel-alt-7.6(which uses crashkernel=xY format), but the x and/or Y
values are changed in rhel-alt-7.6.
For example from crashkernel=2G-:160M to crashkernel=2G-:192M, then we have
no way to determine if the X and/or Y values were distribution
provided or user specified ones.
Since it is recommended to give precedence to user-specified values,
so we cannot do an upgrade in such a case."
Thus turn back to resolve it in kernel, and add a simpler version
which just hacks to use the range:size style in code, and make
rhel-only code easily to maintain.

Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=1507353
Build: https://brewweb.engineering.redhat.com/brew/taskinfo?taskID=16534135
Tested: ppc64le, x86_64 with several memory sizes.
The total memory size we get in kernel is usually slightly less than 2G with
2G memory module machine. The main reason is bios/firmware reserve some area
it will not export all memory as usable to Linux.
2G memory X86 kvm guest test result of the total_mem value:
UEFI boot with ovmf: 0x7ef10000
Legacy boot kvm guest: 0x7ff7cc00
This is also a problem on arm64 UEFI booted system according to my test.
Thus for example crashkernel=1G-2G:128M, if we have a 1G memory
machine, we get total size 1023M from firmware then it will not fall
into 1G-2G thus no memory reserved. User will never know that, it is
hard to let user to know the exact total value we get in kernel
An option is to use dmi/smbios to get physical memory size, but it's not
reliable as well. According to Prarit hardware vendors sometimes screw this up.
Thus round up total size to 128M to workaround this problem.
Posted below patch in upstream, but no response yet:

Subject: [PATCH] platform/x86: thinkpad_acpi: lap or desk mode interface
Newer Lenovo Thinkpad platforms have support to identify whether the
system is on-lap or not using an ACPI DYTC event from the firmware.
This patch provides the ability to retrieve the current mode via sysfs
entrypoints and will be used by userspace for thermal mode and WWAN
functionality

+
+Newer thinkpads and mobile workstations have the ability to determine if
+the device is in deskmode or lapmode. This feature is used by user space
+to decide if WWAN transmission can be increased to maximum power and is
+also useful for understanding the different thermal modes available as
+they differ between desk and lap mode.

+The property is read-only. If the platform doesn't have support the sysfs

Subject: [PATCH] selinux: allow reading labels before policy is loaded
This patch does for `getxattr` what commit 3e3e24b42043 ("selinux: allow
labeling before policy is loaded") did for `setxattr`; it allows
querying the current SELinux label on disk before the policy is loaded.
One of the motivations described in that commit message also drives this
patch: for Fedora CoreOS (and eventually RHEL CoreOS), we want to be
able to move the root filesystem for example, from xfs to ext4 on RAID,
on first boot, at initrd time.[1]
Because such an operation works at the filesystem level, we need to be
able to read the SELinux labels first from the original root, and apply
them to the files of the new root. The previous commit enabled the
second part of this process; this commit enables the first part.

Subject: [PATCH] virt: vbox: Add a few new vmmdev request types to the
userspace whitelist
Upstream VirtualBox has defined and is using a few new request types for
vmmdev requests passed through /dev/vboxguest to the hypervisor.
Add the defines for these to vbox_vmmdev_types.h and add add them to the
whitelists of vmmdev requests which userspace is allowed to make.

VBG_IOCTL_ACQUIRE_GUEST_CAPABILITIES ioctl
Add support for the new VBG_IOCTL_ACQUIRE_GUEST_CAPABILITIES ioctl, this
is necessary for automatic resizing of the guest resolution to match the
VM-window size to work with the new VMSVGA virtual GPU which is now the
new default in VirtualBox.

Subject: [PATCH] xen/events: avoid removing an event channel while handling it
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Today it can happen that an event channel is being removed from the
system while the event handling loop is active. This can lead to a
race resulting in crashes or WARN() splats when trying to access the
irq_info structure related to the event channel.
Fix this problem by using a rwlock taken as reader in the event
handling loop and as writer when deallocating the irq_info structure.
As the observed problem was a NULL dereference in evtchn_from_irq()
make this function more robust against races by testing the irq_info
pointer to be not NULL before dereferencing it.
And finally make all accesses to evtchn_to_irq[row][col] atomic ones
in order to avoid seeing partial updates of an array element in irq
handling. Note that irq handling can be entered only for event channels
which have been valid before, so any not populated row isn't a problem
in this regard, as rows are only ever added and never removed.
This is XSA-331.

ACPI boot
Re-order Tegra194's PCIe aperture mappings to have IO window moved to
64-bit aperture and have the entire 32-bit aperture used for accessing
the configuration space. This makes it to use the entire 32MB of the 32-bit
aperture for ECAM purpose while booting through ACPI.

The RX/TX delays for the Ethernet PHY on the Linksprite pcDuino 3 Nano
are configured in hardware, using resistors that are populated to pull
the RTL8211E's RXDLY/TXDLY pins low or high as needed.
phy-mode should be set to rgmii-id to reflect this. Previously it was
set to rgmii, which used to work but now results in the delays being
disabled again as a result of the bugfix in commit bbc4d71d6354 ("net:
phy: realtek: fix rtl8211e rx/tx delay config").
Tested on two pcDuino 3 Nano boards purchased in 2015. Without this fix,
Ethernet works unreliably on one board and doesn't work at all on the
other.
Fixes: 061035d456c9 ("ARM: dts: sun7i: Add dts file for pcDuino 3 Nano board")

From: Thadeu Lima de Souza Cascardo <cascardo@canonical.com>
When dccps_hc_tx_ccid is freed, ccid timers may still trigger. The reason
del_timer_sync can't be used is because this relies on keeping a reference
to struct sock. But as we keep a pointer to dccps_hc_tx_ccid and free that
during disconnect, the timer should really belong to struct dccp_sock.
This addresses CVE-2020-16119.

From: Thadeu Lima de Souza Cascardo <cascardo@canonical.com>
This reverts commit 2677d20677314101293e6da0094ede7b5526d2b1.
This fixes an issue that after disconnect, dccps_hc_tx_ccid will still be
kept, allowing the socket to be reused as a listener socket, and the cloned
socket will free its dccps_hc_tx_ccid, leading to a later use after free,
when the listener socket is closed.
This addresses CVE-2020-16119.
Fixes: 2677d2067731 (dccp: don't free ccid2_hc_tx_sock struct in dccp_disconnect())

# -------
#
# This variable controls whether we use zstream numbering or not for the

# number for each build. The third number is used for branched builds
# (eg.: for builds with security fixes or hot fixes done outside of the
# batch release process).
#
# For example, with ZSTREAM unset or set to "no", all builds will contain
# a release with only the build number, eg.: kernel-<kernel version>-X.el*,
# where X is the build number. With ZSTREAM set to "yes", we will have
# builds with kernel-<kernel version>-X.Y.Z.el*, where X is the last
# RHEL_RELEASE number before ZSTREAM flag was set to yes, Y will now be the
# build number and Z will always be 1 except if you're doing a branched build
# (when you give RHDISTGIT_BRANCH on the command line, in which case the Z
# number will be incremented instead of the Y).

===================
The Kernel dist-git
===================
The kernel is maintained in a `source tree`_ rather than directly in dist-git.
The specfile is maintained as a `template`_ in the source tree along with a set
of build scripts to generate configurations, (S)RPMs, and to populate the
dist-git repository.
The `documentation`_ for the source tree covers how to contribute and maintain
the tree.
If you're looking for the downstream patch set it's available in the source
tree with "git log master..ark-patches" or
`online`_.
Each release in dist-git is tagged in the source repository so you can easily
check out the source tree for a build. The tags are in the format
name-version-release, but note release doesn't contain the dist tag since the
source can be built in different build roots (Fedora, CentOS, etc.)
.. _source tree: https://gitlab.com/cki-project/kernel-ark.git

Kernel package tips & tricks.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The kernel is one of the more complicated packages in the distro, and
for the newcomer, some of the voodoo in the spec file can be somewhat scary.
This file attempts to document some of the magic.
Speeding up make prep
---------------------
The kernel is nearly 500MB of source code, and as such, 'make prep'
takes a while. The spec file employs some trickery so that repeated
invocations of make prep don't take as long. Ordinarily the %prep
phase of a package will delete the tree it is about to untar/patch.
The kernel %prep keeps around an unpatched version of the tree,
and makes a symlink tree clone of that clean tree and than applies
the patches listed in the spec to the symlink tree.
This makes a huge difference if you're doing multiple make preps a day.
As an added bonus, doing a diff between the clean tree and the symlink
tree is slightly faster than it would be doing two proper copies of the tree.
Build logs.
-----------
There's a convenience helper script in scripts/grab-logs.sh
that will grab the build logs from koji for the kernel version reported
by make verrel
Config hierarchy.
-----------------
Instead of having to maintain a config file for every arch variant we build on,
the kernel spec uses a nested system of configs. Each option CONFIG_FOO is
represented by a single file named CONFIG_FOO which contains the state (=y, =m,
=n). These options are collected in the folder base-generic. Architecture
specific options are set in nested folders. An option set in a nested folder
will override the same option set in one of the higher levels.
The individual CONFIG_FOO files only exist in the pkg-git repository. The RPM
contains kernel-foo.config files which are the result of combining all the
CONFIG_FOO files. The files are combined by running build_configs.sh. This
script _must_ be run each time one of the options is changed.
Example flow:
# Enable the option CONFIG_ABC123 as a module for all arches
echo "CONFIG_ABC123=m" > configs/base-generic/CONFIG_ABC1234
# enable the option CONFIG_XYZ321 for only x86
echo "# CONFIG_XYZ321 is not set" > configs/base-generic/CONFIG_XYZ321
echo "CONFIG_XYZ321=m" > configs/base-generic/x86/CONFIG_XYZ321
# regenerate the combined config files
./build_configs.sh
The file config_generation gives a listing of what folders go into each
config file generated.
Debug options.
--------------
This is a little complicated, as the purpose & meaning of this changes
depending on where we are in the release cycle.
If we are building for a current stable release, 'make release' has
typically been run already, which sets up the following..
- Two builds occur, a 'kernel' and a 'kernel-debug' flavor.
- kernel-debug will get various heavyweight debugging options like
lockdep etc turned on.
If we are building for rawhide, 'make debug' has been run, which changes
the status quo to:
- We only build one kernel 'kernel'
- The debug options are always turned on.
This is done to increase coverage testing, as not many people actually
run kernel-debug.
The debug options are managed in a separate heierarchy under base-debug. This
works in a similar manner to base-generic. More deeply nested folders, again,
override options. The file config_generation gives a listing of what folders
go into each config file generated.

Config TODOs:
* review & disable a bunch of the I2C, RTC, DVB, SOUND options.
Spec file TODOs:
* modules-extra: Do a few more things to make it a bit more robust.
- Allow for comments in the mod-extra.list file.
- Don't fail the build if a module is listed but not built (maybe).
- See if it can be tied into Kconfig instead of module names.

Ethernet PHY provides RX and TX delay on both models, A and B. Although
schematic for model A suggests only TX delay, network never worked with
such configuration.
Fix ethernet node to reflect PHY delays.

Subject: [PATCH] arm64: tegra: Use valid PWM period for VDD_GPU on Tegra210
From: Thierry Reding <treding@nvidia.com>
The PWM on Tegra210 can run at a maximum frequency of 48 MHz and cannot
reach the minimum period is 5334 ns. The currently configured period of
4880 ns is not within the valid range, so set it to 8000 ns. This value
was taken from the downstream DTS files and seems to work fine.
