From a397b69ce33d811aba7d64d54b5c8e0efb86fd15 Mon Sep 17 00:00:00 2001
From: Zdenek Kabelac <zkabelac@redhat.com>
Date: Fri, 10 May 2019 14:40:11 +0200
Subject: [PATCH] metadata: allow reading metadata with invalid creation_time
lvm2 till version 2.02.169 (commit 78d004efa8a1809cea68283e6204edfa9d7c1091)
was printing invalid creation_time argument into metadata on 32bit arch.
However with commit ba9820b14223b731125c83dbc9709aa44fdcdbf1 we started
to properly validate all input numbers and thus we refused to accept
invalid metadata with 'garbage' string - but this results in the
situation where metadata produced on older lvm2 on 32 bit architecture
will become unreadable after upgrade.
To fix this case - extend libdm parser in a way, that whenever we
find error integer value, we also check if the parsed value is not for
creation_time node and in this case we let the metadata pass through
with made-up date 2018-05-24 (release date of 2.02.169).

Subject: [PATCH] udev: remove unsupported OPTIONS+="event_timeout" rule
The OPTIONS+="event_timeout" is Unsupported since systemd/udev version 216,
that is ~5 years ago.
Since systemd/udev version 243, there's a new message printed if unsupported
OPTIONS value is used:
Invalid value for OPTIONS key, ignoring: 'event_timeout=180'

Date: Wed, 24 Jul 2019 11:22:32 +0200
Subject: [PATCH] dmeventd configurable idle exit time
dmeventd nominally exits after 1 hour of idle time. There are use cases for
this, esp. with socket activation, but also cases where users don't expect
dmeventd to exit.
Provide a tuning knob via environment variable, DMEVENTD_IDLE_EXIT_TIMEOUT,
that can be -1 to not exit, or a configurable time for different idle exit.

From 84ecc2f6eb1cb12e6d44818f94fa49b50f06e6ac Mon Sep 17 00:00:00 2001
From: Gen Zhang <blackgod016574@gmail.com>

Subject: consolemap: Fix a memory leaking bug in drivers/tty/vt/consolemap.c
In function con_insert_unipair(), when allocation for p2 and p1[n]
fails, ENOMEM is returned, but previously allocated p1 is not freed,
remains as leaking memory. Thus we should free p1 as well when this
allocation fails.

From: Anthony G. Basile <blueness@gentoo.org>
This patch adds support for a restricted user-controlled namespace on
tmpfs filesystem used to house PaX flags. The namespace must be of the
form user.pax.* and its value cannot exceed a size of 8 bytes.
This is needed even on all Gentoo systems so that XATTR_PAX flags
are preserved for users who might build packages using portage on
a tmpfs system with a non-hardened kernel and then switch to a
hardened kernel with XATTR_PAX enabled.
The namespace is added to any user with Extended Attribute support
enabled for tmpfs. Users who do not enable xattrs will not have
the XATTR_PAX flags preserved.

WARNING - this version of the patch works with version 4.9+ of gcc and with
kernel version 3.15.x+ and should NOT be applied when compiling on older
versions due to name changes of the flags with the 4.9 release of gcc.
Use the older version of this patch hosted on the same github for older
versions of gcc. For example:
corei7 --> nehalem
corei7-avx --> sandybridge
core-avx-i --> ivybridge
core-avx2 --> haswell
For more, see: https://gcc.gnu.org/gcc-4.9/changes.html
It also changes 'atom' to 'bonnell' in accordance with the gcc v4.9 changes.
Note that upstream is using the deprecated 'match=atom' flags when I believe it
should use the newer 'march=bonnell' flag for atom processors.
I have made that change to this patch set as well. See the following kernel
bug report to see if I'm right: https://bugzilla.kernel.org/show_bug.cgi?id=77461
This patch will expand the number of microarchitectures to include new
processors including: AMD K10-family, AMD Family 10h (Barcelona), AMD Family
14h (Bobcat), AMD Family 15h (Bulldozer), AMD Family 15h (Piledriver), AMD
Family 16h (Jaguar), Intel 1st Gen Core i3/i5/i7 (Nehalem), Intel 1.5 Gen Core
i3/i5/i7 (Westmere), Intel 2nd Gen Core i3/i5/i7 (Sandybridge), Intel 3rd Gen
Core i3/i5/i7 (Ivybridge), Intel 4th Gen Core i3/i5/i7 (Haswell), and Intel 5th
Gen Core i3/i5/i7 (Broadwell). It also offers the compiler the 'native' flag.
Small but real speed increases are measurable using a make endpoint comparing
a generic kernel to one built with one of the respective microarchs.
See the following experimental evidence supporting this statement:

Subject: consolemap: Fix a memory leaking bug in drivers/tty/vt/consolemap.c
In function con_insert_unipair(), when allocation for p2 and p1[n]
fails, ENOMEM is returned, but previously allocated p1 is not freed,
remains as leaking memory. Thus we should free p1 as well when this
allocation fails.

Subject: [PATCH 2/2] PCI: Add function 1 DMA alias quirk for Highpoint RocketRAID 644L
Date: Fri, 2 Mar 2018 11:36:33 +0100
The Highpoint RocketRAID 644L uses a Marvel 88SE9235 controller, as with
other Marvel controllers this needs a function 1 DMA alias quirk.
Note the RocketRAID 642L uses the same Marvel 88SE9235 controller and
already is listed with a function 1 DMA alias quirk.

Subject: [PATCH] ARM: omap2: hide omap3_save_secure_ram on non-OMAP3 builds
In configurations without CONFIG_OMAP3 but with secure RAM support,
we now run into a link failure:
arch/arm/mach-omap2/omap-secure.o: In function `omap3_save_secure_ram':
omap-secure.c:(.text+0x130): undefined reference to `save_secure_ram_context'
The omap3_save_secure_ram() function is only called from the OMAP34xx
power management code, so we can simply hide that function in the
appropriate #ifdef.
Fixes: d09220a887f7 ("ARM: OMAP2+: Fix SRAM virt to phys translation for save_secure_ram_context")

Like the Highpoint Rocketraid 642L and cards using a Marvel 88SE9235

of a custom driver, this is the only way to make it work under Linux.
Note that even though the card is called to 644L, it has a product-id

From faec44b6838312484d63e82286087cf2d5ebb891 Mon Sep 17 00:00:00 2001
From: Hans de Goede <hdegoede@redhat.com>
Date: Fri, 12 Jan 2018 00:36:48 -0800
Subject: [PATCH] Input: goodix - disable IRQs while suspended
We should not try to do any i2c transfers before the controller is
resumed (which happens before our resume method gets called).
So we need to disable our IRQ while suspended to enforce this. The
code paths for devices with GPIOs for the int and reset pins already
disable the IRQ the through goodix_free_irq().
This commit also disables the IRQ while suspended for devices without
GPIOs for the int and reset pins.
This fixes the i2c bus sometimes getting stuck after a suspend/resume
causing the touchscreen to sometimes not work after a suspend/resume.
This has been tested on a GPD pocked device.

From 57ebd808a97d7c5b1e1afb937c2db22beba3c1f8 Mon Sep 17 00:00:00 2001

Subject: [PATCH] netfilter: add back stackpointer size checks
The rationale for removing the check is only correct for rulesets
generated by ip(6)tables.
In iptables, a jump can only occur to a user-defined chain, i.e.
because we size the stack based on number of user-defined chains we
cannot exceed stack size.
However, the underlying binary format has no such restriction,
and the validation step only ensures that the jump target is a
valid rule start point.
IOW, its possible to build a rule blob that has no user-defined
chains but does contain a jump.
If this happens, no jump stack gets allocated and crash occurs
because no jumpstack was allocated.
Fixes: 7814b6ec6d0d6 ("netfilter: xtables: don't save/restore jumpstack offset")

Subject: [PATCH 11/34] x86/entry/32: Handle Entry from Kernel-Mode on
Entry-Stack
It can happen that we enter the kernel from kernel-mode and
on the entry-stack. The most common way this happens is when
we get an exception while loading the user-space segment
registers on the kernel-to-userspace exit path.
The segment loading needs to be done after the entry-stack
switch, because the stack-switch needs kernel %fs for
per_cpu access.
When this happens, we need to make sure that we leave the
kernel with the entry-stack again, so that the interrupted
code-path runs on the right stack when switching to the
user-cr3.
We do this by detecting this condition on kernel-entry by
checking CS.RPL and %esp, and if it happens, we copy over
the complete content of the entry stack to the task-stack.
This needs to be done because once we enter the exception
handlers we might be scheduled out or even migrated to a
different CPU, so that we can't rely on the entry-stack
contents. We also leave a marker in the stack-frame to
detect this condition on the exit path.
On the exit path the copy is reversed, we copy all of the
remaining task-stack back to the entry-stack and switch
to it.

Subject: [PATCH 12/34] x86/entry/32: Simplify debug entry point
The common exception entry code now handles the
entry-from-sysenter stack situation and makes sure to leave
with the same stack as it entered the kernel.
So there is no need anymore for the special handling in the
debug entry code.

pti_set_user_pgtbl
With the way page-table folding is implemented on 32 bit, we
are not only setting PGDs with this functions, but also PUDs
and even PMDs. Give the function a more generic name to
reflect that.

With PTI we need to map the per-process LDT into the kernel
address-space for each process, so we need separate kernel
PMDs per PGD.

Subject: [PATCH 17/34] x86/pgtable/32: Allocate 8k page-tables when PTI is
enabled
Allocate a kernel and a user page-table root when PTI is
enabled. Also allocate a full page per root for PAE because
otherwise the bit to flip in cr3 to switch between them
would be non-constant, which creates a lot of hassle.
Keep that for a later optimization.

These two functions are required for PTI on 32 bit:

Subject: [PATCH 21/34] x86/mm/pae: Populate valid user PGD entries
Generic page-table code populates all non-leaf entries with
_KERNPG_TABLE bits set. This is fine for all paging modes
except PAE.
In PAE mode only a subset of the bits is allowed to be set.
Make sure we only set allowed bits by masking out the
reserved bits.
