Subject: [PATCH 1/2] Input: gpio_keys - Allow suppression of input events for
|
||||
wakeup button presses
|
||||
|
||||
In some cases it is undesirable for a wakeup button to send input events
|
||||
to userspace if pressed to wakeup the system (if pressed during suspend).
|
||||
|
||||
A typical example of this is the power-button on laptops / tablets,
|
||||
sending a KEY_POWER event to userspace when woken up with the power-button
|
||||
will cause userspace to immediately suspend the system again which is
|
||||
undesirable.
|
||||
|
||||
For power-buttons attached to a PMIC, or handled by e.g. ACPI, not sending
|
||||
an input event in this case is take care of by the PMIC / ACPI hardware /
|
||||
code. But in the case of a GPIO button we need to explicitly suppress the
|
||||
sending of the input event.
|
||||
|
||||
This commit adds support for this by adding a no_wakeup_events bool to
|
||||
struct gpio_keys_button, which platform code can set to suppress the
|
||||
input events for presses of wakeup keys during suspend.

Changes in v2:
|
||||
-This is a rewrite if my "Input: gpio_keys - Do not report wake button
|
||||
presses as evdev events" patch.
|
||||
-Instead of unconditionally ignoring presses of all wake-up buttons during
|
||||
suspend, this rewrite makes this configurable per button
|
||||
-This version uses a timer to delay clearing the suspended flag for software
|
||||
debouncing, rather then jiffy compare magic

When converting to a shared library in ac5a181d065d ("cpupower: Add
|
||||
cpuidle parts into library"), cpu_freq_cpu_exists was converted to
|
||||
cpupower_is_cpu_online. cpu_req_cpu_exists returned 0 on success and
|
||||
-ENOSYS on failure whereas cpupower_is_cpu_online returns 1 on success.
|
||||
Check for the correct return value in cpufreq-set.

||||
atomic with the stateid update", NFSv4 has been inserting locks in rpciod
|
||||
worker context. The result is that the file_lock's fl_nspid is the
|
||||
kworker's pid instead of the original userspace pid.
|
||||
|
||||
The fl_nspid is only used to represent the namespaced virtual pid number
|
||||
when displaying locks or returning from F_GETLK. There's no reason to set
|
||||
it for every inserted lock, since we can usually just look it up from
|
||||
fl_pid. So, instead of looking up and holding struct pid for every lock,
|
||||
let's just look up the virtual pid number from fl_pid when it is needed.
|
||||
That means we can remove fl_nspid entirely.
|
||||
|
||||
The translaton and presentation of fl_pid should handle the following four
|
||||
cases:
|
||||
|
||||
1 - F_GETLK on a remote file with a remote lock:
|
||||
In this case, the filesystem should determine the l_pid to return here.
|
||||
Filesystems should indicate that the fl_pid represents a non-local pid
|
||||
value that should not be translated by returning an fl_pid <= 0.
|
||||
|
||||
2 - F_GETLK on a local file with a remote lock:
|
||||
This should be the l_pid of the lock manager process, and translated.
|
||||
|
||||
3 - F_GETLK on a remote file with a local lock, and
|
||||
4 - F_GETLK on a local file with a local lock:
|
||||
These should be the translated l_pid of the local locking process.
|
||||
|
||||
Fuse was already doing the correct thing by translating the pid into the
|
||||
caller's namespace. With this change we must update fuse to translate
|
||||
to init's pid namespace, so that the locks API can then translate from
|
||||
init's pid namespace into the pid namespace of the caller.
|
||||
|
||||
With this change, the locks API will expect that if a filesystem returns
|
||||
a remote pid as opposed to a local pid for F_GETLK, that remote pid will
|
||||
be <= 0. This signifies that the pid is remote, and the locks API will
|
||||
forego translating that pid into the pid namespace of the local calling
|
||||
process.
|
||||
|
||||
Finally, we convert remote filesystems to present remote pids using
|
||||
negative numbers. Have lustre, 9p, ceph, cifs, and dlm negate the remote
|
||||
pid returned for F_GETLK lock requests.
|
||||
|
||||
Since local pids will never be larger than PID_MAX_LIMIT (which is
|
||||
currently defined as <= 4 million), but pid_t is an unsigned int, we
|
||||
should have plenty of room to represent remote pids with negative
|
||||
numbers if we assume that remote pid numbers are similarly limited.
|
||||
|
||||
If this is not the case, then we run the risk of having a remote pid
|
||||
returned for which there is also a corresponding local pid. This is a
|
||||
problem we have now, but this patch should reduce the chances of that
|
||||
occurring, while also returning those remote pid numbers, for whatever
|
||||
that may be worth.

Subject: [PATCH] mm, thp: Do not make page table dirty unconditionally in
|
||||
touch_p[mu]d()
|
||||
|
||||
Currently, we unconditionally make page table dirty in touch_pmd().
|
||||
It may result in false-positive can_follow_write_pmd().
|
||||
|
||||
We may avoid the situation, if we would only make the page table entry
|
||||
dirty if caller asks for write access -- FOLL_WRITE.
|
||||
|
||||
The patch also changes touch_pud() in the same way.

Subject: [PATCH 01/16] platform/x86: Add driver for ACPI INT0002 Virtual GPIO
|
||||
device
|
||||
|
||||
Some peripherals on Bay Trail and Cherry Trail platforms signal a
|
||||
Power Management Event (PME) to the Power Management Controller (PMC)
|
||||
to wakeup the system. When this happens software needs to explicitly
|
||||
clear the PME bus 0 status bit in the GPE0a_STS register to avoid an
|
||||
IRQ storm on IRQ 9.
|
||||
|
||||
This is modelled in ACPI through the INT0002 ACPI device, which is
|
||||
called a "Virtual GPIO controller" in ACPI because it defines the
|
||||
event handler to call when the PME triggers through _AEI and _L02
|
||||
methods as would be done for a real GPIO interrupt in ACPI.
|
||||
|
||||
This commit adds a driver which registers the Virtual GPIOs expected
|
||||
by the DSDT on these devices, letting gpiolib-acpi claim the
|
||||
virtual GPIO and install a GPIO-interrupt handler which call the _L02
|
||||
handler as it would for a real GPIO controller.

Changes in v2:
|
||||
-Remove dev_err after malloc failure
|
||||
-Remove unused empty runtime pm callbacks
|
||||
-s/GPE0A_PME_/GPE0A_PME_B0_/
|
||||
-Fixed some checkpatch warnings (I forgot to run checkpatch on v1)
|
||||
|
||||
Changes in v3:
|
||||
-Rewrite as gpiochip driver letting gpiolib-acpi deal with claiming the pin
|
||||
0x0002 and calling the _L02 event handler when the virtual gpio-irq triggers
|
||||
-Rebase on 4.12-rc1
|
||||
|
||||
Changes in v4:
|
||||
-Drop device_init_wakeup() from _probe(), use pm_system_wakeup() instead
|
||||
of pm_wakeup_hard_event(chip->parent)
|
||||
-Improve commit message
|
||||
|
||||
Changes in v5:
|
||||

Subject: [PATCH] usb: usbtest: fix NULL pointer dereference
|
||||
|
||||
If the usbtest driver encounters a device with an IN bulk endpoint but
|
||||
no OUT bulk endpoint, it will try to dereference a NULL pointer
|
||||
(out->desc.bEndpointAddress). The problem can be solved by adding a
|
||||
missing test.

Subject: [PATCH 2/2] Input: soc_button_array - Suppress power button presses
|
||||
during suspend
|
||||
|
||||
If the power-button is pressed to wakeup the laptop/tablet from suspend
|
||||
and we report a KEY_POWER event to userspace when woken up this will cause
|
||||
userspace to immediately suspend the system again which is undesirable.
|
||||
|
||||
This commit sets the new no_wakeup_events flag in the gpio_keys_button
|
||||
struct for the power-button suppressing the undesirable KEY_POWER input
|
||||
events on wake-up.

Subject: [PATCH 02/16] mfd: Add Cherry Trail Whiskey Cove PMIC driver
|
||||
|
||||
Add mfd driver for Intel CHT Whiskey Cove PMIC, based on various non
|
||||
upstreamed CHT Whiskey Cove PMIC patches.
|
||||
|
||||
This is a somewhat minimal version which adds irqchip support and cells
|
||||
for: ACPI PMIC opregion support, the i2c-controller driving the external
|
||||
charger irc and the pwrsrc/extcon block.
|
||||
|
||||
Further cells can be added in the future if/when drivers are upstreamed
|
||||
for them.

|
||||
Changes in v2:
|
||||
-Since this uses plain mfd and not the intel_soc_pmic stuff give it
|
||||
its own Kconfig and allow this to be built as a module
|
||||
-Add missing #include <acpi/acpi_bus.h>
|
||||
|
||||
Changes in v3:
|
||||
-Drop #include <acpi/acpi_bus.h> again, not the right fix for the build errors
|
||||
-Error out when the upper byte of the register-address passed to the regmap
|
||||
functions is 0 rather then hardcoding an address in that case
|
||||
-Various minor style tweaks / cleanups
|
||||
-Move defines of regulator register addresses to intel_pmic_chtwc.c,
|
||||
it is the only place where they are used
|
||||
-Drop now empty include/linux/mfd/intel_chtwc.h
|
||||
-Rename intel_soc_pmic_chtwc.c to intel_cht_wc.c to match Kconfig option name
|
||||
-Add irqchip support
|
||||
-Add external charger cell
|
||||
-Add pwrsrc cell
|
||||
|
||||
Changes in v4:
|
||||
-Use PLATFORM_DEVID_NONE
|
||||
|
||||
Changes in v5:
|
||||
-Change Kconfig option from tristate to boolean and add a select for the
|
||||
i2c-bus driver, this is necessary because the chtwc PMIC provides an ACPI
|
||||
OPRegion handler, which must be available before other drivers using it
|
||||
are loaded, which can only be ensured if the mfd, opregion and i2c-bus
|
||||
drivers are built in. This fixes errors like these during boot:
|
||||
mmc0: SDHCI controller on ACPI [80860F14:00] using ADMA
|
||||
ACPI Error: No handler for Region [REGS] (ffff93543b0cc3a8) [UserDefinedRegion] (20170119/evregion-166)
|
||||
ACPI Error: Region UserDefinedRegion (ID=143) has no handler (20170119/exfldio-299)

|
||||
acpi 80860F14:02: Failed to change power state to D0
|
||||
-Some minor style and capitalization fixes from review by Lee Jones
|
||||
|
||||
Changes in v6:
|
||||
-Fix Kconfig depends and selects to fix warning reported by kbuild test robot
|
||||
|
||||
Changes in v7:
|
||||
-Add explanation why this is a bool and why it selects i2c-designwaree
|
||||
to the help text rather then as comments in the Kconfig
|
||||
|
||||
Changes in v8:
|
||||
-Remove MODULE macros, etc. now that this driver is a bool in Kconfig
|
||||
|
||||
Changes in v9:
|
||||
-Some whitespace tweaks
|
||||
-Return -EINVAL from probe on invalid irq
|
||||
-Use probe_new i2c_driver callback

Subject: [PATCH 2/2] power: supply: max17042_battery: Fix ACPI interrupt
|
||||
issues
|
||||
|
||||
On some x86/ACPI boards the DSDT defines an ACPI event handler for
|
||||
the max17047 IRQ, this causes several problems:
|
||||
|
||||
1) We need to share the IRQ to avoid an error getting it
|
||||
|
||||
2) Even of we are willing to share, we may fail to share because some
|
||||
DSDTs claim it exclusivly
|
||||
|
||||
3) If we are unable to share the IRQ, or the IRQ is only listed as an
|
||||
ACPI event source and not in the max1704 firmware node, then the
|
||||
charge threshold IRQ (which is used to give an IRQ every 1 percent
|
||||
charge change) becomes a problem, the ACPI event handler will not
|
||||
update this to the next 1 percent threshold, so the IRQ keeps firing
|
||||
and we get an IRQ storm pegging 1 CPU core.
|
||||
|
||||
This happens despite the max17042 driver not setting the charge
|
||||
threshold because Windows uses it and leaves it set on reboot.
|
||||
|
||||
So if we are unable to get the IRQ we need to reprogram the
|
||||
charge threshold to its disabled setting.
|
||||
|
||||
This commit fixes al of the above, while at it it also makes the error
|
||||
msg when being unable to get the IRQ consistent with other messages.

Some Bay Trail devices use a GPI1 regulator field (address 0x4c) in

their 0x8d power OpRegion, add support for this.
|

This fixes AE_BAD_PARAMETER errors getting thrown on these devices and

|

found on some x86 tablets
|
||||
|
||||
On some x86 tablets with a silead touchscreen the windows logo on the

front is a capacitive home button. Touching this button results in a touch
|
||||
with bits 12-15 of the Y coordinates set, while normally only the lower 12

are used.
|

|

Detect this and report a KEY_LEFTMETA press when this happens. Note for
|

now we only respond to the Y coordinate bits 12-15 containing 0x01, on some
|
||||
tablets *without* a capacative button I've noticed these bits containing
|
||||
0x04 when crossing the edges of the screen.

|

|
||||
On some x86 tablets with a Goodix touchscreen, the Windows logo on the

front is a capacitive home button. Touching this button results in a touch
|
||||
with bit 4 of the first byte set, while only the lower 4 bits (0-3) are

used to indicate the number of touches.
|
||||
|
||||
Report a KEY_LEFTMETA press when this happens.
|
||||
|
||||
Note that the hardware might support more than one button, in which
|
||||
case the "id" byte of coor_data would identify the button in question.
|
||||
This is not implemented as we don't have access to hardware with
|
||||
multiple buttons.

Subject: [PATCH 12/16] Input: gpio_keys - Do not report wake button presses as
|
||||
evdev events
|
||||
|
||||
If a button is a wake button, it may still be bouncing from the press
|
||||
to wakeup the device by the time the gpio interrupts get enabled again
|
||||
and / or the gpio_keys_report_state call from gpio_keys_resume may
|
||||
find the button still pressed and report this as a new press.
|
||||
|
||||
This is undesirable, esp. since the powerbutton on tablets is typically
|
||||
a wakeup source and uses the gpio_keys driver on some tablets, leading
|
||||
to userspace immediately re-suspending the tablet after the powerbutton
|
||||
is pressed, due to it seeing a powerbutton press.
|
||||
|
||||
This commit ignores wakeup button presses for the first 1 second after
|
||||
resume (and while resumed, as the workqueue may run before the resume
|
||||
function runs), avoiding this problem.

|
||||
Note: maybe we should make WAKE_DEBOUNCE part of gpio_keys_button and
|
||||
only do this when drivers / platform-data set this to a non-zero value ?

Subject: [PATCH 14/16] mmc: sdhci-acpi: Workaround conflict with PCI wifi on
|
||||
GPD Win handheld
|
||||
|
||||
GPDwin uses PCI wifi which conflicts with SDIO's use of
|
||||
acpi_device_fix_up_power() on child device nodes. Specifically
|
||||
acpi_device_fix_up_power() causes the wifi module to get turned off.
|
||||
Identifying GPDwin is problematic, but since SDIO is only used for wifi,
|
||||
the presence of the PCI wifi card in the expected slot with an ACPI
|
||||
companion node, is used to indicate that acpi_device_fix_up_power() should
|
||||
be avoided.

Subject: [PATCH 15/16] i2c-cht-wc: Add Intel Cherry Trail Whiskey Cove SMBUS
|
||||
controller driver
|
||||
|
||||
The Intel Cherry Trail Whiskey Cove PMIC does not contain a builtin
|
||||
battery charger, instead boards with this PMIC use an external TI
|
||||
bq24292i charger IC, which is connected to a SMBUS controller built into
|
||||
the PMIC.
|
||||
|
||||
This commit adds an i2c-bus driver for the PMIC's builtin SMBUS
|
||||
controller. The probe function for this i2c-bus will also register an
|
||||
i2c-client for the TI bq24292i charger after the i2c-bus has been
|
||||
registered.
|
||||
|
||||
Note that several device-properties are set on the client-device to
|
||||
tell the bq24190 power-supply driver to integrate the Whiskey Cove PMIC
|
||||
and e.g. use the PMIC's BC1.2 detection (through extcon) to determine
|
||||
the maximum input current.

Subject: [PATCH 16/16] Input: silead: Do not try to directly access the GPIO
|
||||
when using ACPI pm
|
||||
|
||||
On some x86 tablets we cannot directly access the GPIOs as they are
|
||||
claimed by the ACPI tables, so check it the i2c client is not being
|
||||
power-managed by ACPI before trying to get the power pin GPIO.
|
||||
|
||||
Note this is a workaround patch to fix this until Andy' gpiolib-ACPI
|
||||
patches which make gpiolib more strict land, once those are landed this
|
||||
patch is no longer needed.

Subject: [1/2] kvm: vmx: Reinstate support for CPUs without virtual NMI
|

|
||||
|
||||
This is more or less a revert of commit 2c82878b0cb3 ("KVM: VMX: require
|
||||
virtual NMI support", 2017-03-27); it turns out that Core 2 Duo machines
|
||||
only had virtual NMIs in some SKUs.
|
||||
|
||||
The revert is not trivial because in the meanwhile there have been several
|
||||
fixes to nested NMI injection. Therefore, the entire vNMI state is moved
|
||||
to struct loaded_vmcs.
|
||||
|
||||
Another change compared to before the patch is a simplification here:
|
||||
|
||||
if (unlikely(!cpu_has_virtual_nmis() && vmx->soft_vnmi_blocked &&
|
||||
!(is_guest_mode(vcpu) && nested_cpu_has_virtual_nmis(
|
||||
get_vmcs12(vcpu))))) {
|
||||
|
||||
The final condition here is always true (because nested_cpu_has_virtual_nmis
|
||||
is always false) and is removed.
|
||||
|
||||

ipv6 compare with the fast socket information to make sure we're doing

When doing my reuseport rework I screwed up and changed a
|
||||
|
||||
if (hlist_empty(&tb->owners))
|
||||
|
||||
to
|
||||
|
||||
if (!hlist_empty(&tb->owners))
|
||||
|
||||
This is obviously bad as all of the reuseport/reuse logic was reversed,
|
||||
which caused weird problems like allowing an ipv4 bind conflict if we
|
||||
opened an ipv4 only socket on a port followed by an ipv6 only socket on
|
||||
the same port.

Subject: [PATCH 2/4] efi: Add an EFI signature blob parser
|
||||
|
||||
X.509 certificates are loaded into the specified keyring as asymmetric type
|
||||
keys.
|
||||
Add a function to parse an EFI signature blob looking for elements of
|
||||
interest. A list is made up of a series of sublists, where all the
|
||||
elements in a sublist are of the same type, but sublists can be of
|
||||
different types.
|
||||
|
||||
For each sublist encountered, the function pointed to by the
|
||||
get_handler_for_guid argument is called with the type specifier GUID and
|
||||
returns either a pointer to a function to handle elements of that type or
|
||||
NULL if the type is not of interest.
|
||||
|
||||
If the sublist is of interest, each element is passed to the handler
|
||||
function in turn.

Subject: [PATCH] Add option to automatically enforce module signatures when 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 enforces this automatically when enabled.

When the tuner was split from m88rs2000 the attach function is in wrong

place.

Move to dm04_lme2510_tuner to trap errors on failure and removing

a call to lme_coldreset.

Prevents driver starting up without any tuner connected.

Subject: macsec: avoid heap overflow in skb_to_sgvec
|
||||
|
||||
While this may appear as a humdrum one line change, it's actually quite
|
||||
important. An sk_buff stores data in three places:
|
||||
|
||||
1. A linear chunk of allocated memory in skb->data. This is the easiest
|
||||
one to work with, but it precludes using scatterdata since the memory
|
||||
must be linear.
|
||||
2. The array skb_shinfo(skb)->frags, which is of maximum length
|
||||
MAX_SKB_FRAGS. This is nice for scattergather, since these fragments
|
||||
can point to different pages.
|
||||
3. skb_shinfo(skb)->frag_list, which is a pointer to another sk_buff,
|
||||
which in turn can have data in either (1) or (2).
|
||||
|
||||
The first two are rather easy to deal with, since they're of a fixed
|
||||
maximum length, while the third one is not, since there can be
|
||||
potentially limitless chains of fragments. Fortunately dealing with
|
||||
frag_list is opt-in for drivers, so drivers don't actually have to deal
|
||||
with this mess. For whatever reason, macsec decided it wanted pain, and
|
||||
so it explicitly specified NETIF_F_FRAGLIST.
|
||||
|
||||
Because dealing with (1), (2), and (3) is insane, most users of sk_buff
|
||||
doing any sort of crypto or paging operation calls a convenient function
|
||||
called skb_to_sgvec (which happens to be recursive if (3) is in use!).
|
||||
This takes a sk_buff as input, and writes into its output pointer an
|
||||
array of scattergather list items. Sometimes people like to declare a
|
||||
fixed size scattergather list on the stack; othertimes people like to
|
||||
allocate a fixed size scattergather list on the heap. However, if you're
|
||||
doing it in a fixed-size fashion, you really shouldn't be using
|
||||
NETIF_F_FRAGLIST too (unless you're also ensuring the sk_buff and its
|
||||
frag_list children arent't shared and then you check the number of
|
||||
fragments in total required.)
|
||||
|
||||
Macsec specifically does this:
|
||||
|
||||
size += sizeof(struct scatterlist) * (MAX_SKB_FRAGS + 1);
|
||||
tmp = kmalloc(size, GFP_ATOMIC);
|
||||
*sg = (struct scatterlist *)(tmp + sg_offset);
|
||||
...
|
||||
sg_init_table(sg, MAX_SKB_FRAGS + 1);
|
||||
skb_to_sgvec(skb, sg, 0, skb->len);
|
||||
|
||||
Specifying MAX_SKB_FRAGS + 1 is the right answer usually, but not if you're
|
||||
using NETIF_F_FRAGLIST, in which case the call to skb_to_sgvec will
|
||||
overflow the heap, and disaster ensues.

|
||||
|
||||
In certain situations kernel tracking seems to be getting confused
|
||||
and incorrectly reporting the slot of a contact. On example is when
|
||||
the user does a three finger click or tap and then places two fingers
|
||||
on the touchpad in the same area. The kernel tracking code seems to
|
||||
continue to think that there are three contacts on the touchpad and
|
||||
incorrectly alternates the slot of one of the contacts. The result that
|
||||
is the input subsystem reports a stream of button press and release
|
||||
events as the reported slot changes.
|
||||
|
||||
Kernel tracking was originally enabled to prevent cursor jumps, but it
|
||||
is unclear how much of an issue kernel jumps actually are. This patch
|
||||
simply disabled kernel tracking for now.

This imports those certificates into the system trusted keyring. This

load. The shim UEFI bootloader has a similar certificate list stored
|

in the 'MokListRT' variable. We import those as well.

|

In the opposite case, Secure Boot maintains a list of disallowed

forbid the use within the kernel of any key with a matching hash.

Subject: [PATCH 2/2] MODSIGN: Support not importing certs from db
|

Date: Fri, 5 May 2017 08:21:59 +0100
|
||||
Subject: [PATCH 4/4] MODSIGN: Allow the "db" UEFI variable to be suppressed
|
||||
|
||||
If a user tells shim to not use the certs/hashes in the UEFI db variable
|
||||
for verification purposes, shim will set a UEFI variable called MokIgnoreDB.
|
||||
Have the uefi import code look for this and not import things from the db
|
||||
variable.
|
||||
for verification purposes, shim will set a UEFI variable called
|
||||
MokIgnoreDB. Have the uefi import code look for this and ignore the db
|
||||
variable if it is found.

Subject: [PATCH] PCI: Lock down BAR access when module security is enabled
|
||||
|
||||
Any hardware that can potentially generate DMA has to be locked down from
|
||||
userspace in order to avoid it being possible for an attacker to modify
|
||||
kernel code, allowing them to circumvent disabled module loading or module
|
||||
signing. Default to paranoid - in future we can potentially relax this for
|
||||
sufficiently IOMMU-isolated devices.

|

|

Originally reported by Adam and Dusty, it appears we have a small
|
||||
race window in kauditd_thread(), as documented in the Fedora BZ:
|
||||
|
||||
* https://bugzilla.redhat.com/show_bug.cgi?id=1459326#c35
|
||||
|
||||
"This issue is partly due to the read-copy nature of RCU, and
|
||||
partly due to how we sync the auditd_connection state across
|
||||
kauditd_thread and the audit control channel. The kauditd_thread
|
||||
thread is always running so it can service the record queues and
|
||||
emit the multicast messages, if it happens to be just past the
|
||||
"main_queue" label, but before the "if (sk == NULL || ...)"
|
||||
if-statement which calls auditd_reset() when the new auditd
|
||||
connection is registered it could end up resetting the auditd
|
||||
connection, regardless of if it is valid or not. This is a rather
|
||||
small window and the variable nature of multi-core scheduling
|
||||
explains why this is proving rather difficult to reproduce."
|
||||
|
||||
The fix is to have functions only call auditd_reset() when they
|
||||
believe that the kernel/auditd connection is still valid, e.g.
|
||||
non-NULL, and to have these callers pass their local copy of the
|
||||
auditd_connection pointer to auditd_reset() where it can be compared
|
||||
with the current connection state before resetting. If the caller
|
||||
has a stale state tracking pointer then the reset is ignored.
|
||||
|
||||
We also make a small change to kauditd_thread() so that if the
|
||||
kernel/auditd connection is dead we skip the retry queue and send the
|
||||
records straight to the hold queue. This is necessary as we used to
|
||||
rely on auditd_reset() to occasionally purge the retry queue but we
|
||||
are going to be calling the reset function much less now and we want
|
||||
to make sure the retry queue doesn't grow unbounded.

|

I'm Seunghun Han, and I work for National Security Research Institute of
|
||||
South Korea.
|
||||
|
||||
I have been doing a research on ACPI and found an ACPI cache leak in ACPI
|
||||
early abort cases.
|
||||
|
||||
Boot log of ACPI cache leak is as follows:

|
||||
|
||||
I analyzed this memory leak in detail. I found that “Acpi-State” cache and
|
||||
“Acpi-Parse” cache were merged because the size of cache objects was same
|
||||
slab cache size.
|
||||
|
||||
I finally found “Acpi-Parse” cache and “Acpi-ParseExt” cache were leaked
|
||||
using SLAB_NEVER_MERGE flag in kmem_cache_create() function.

||||

||||

|
||||
|
||||
When early abort is occurred due to invalid ACPI information, Linux kernel
|
||||
terminates ACPI by calling acpi_terminate() function. The function calls
|
||||
acpi_ut_delete_caches() function to delete local caches (acpi_gbl_namespace_
|
||||
cache, state_cache, operand_cache, ps_node_cache, ps_node_ext_cache).
|
||||
|
||||
But the deletion codes in acpi_ut_delete_caches() function only delete
|
||||
slab caches using kmem_cache_destroy() function, therefore the cache
|
||||
objects should be flushed before acpi_ut_delete_caches() function.
|
||||
|
||||
“Acpi-Parse” cache and “Acpi-ParseExt” cache are used in an AML parse
|
||||
function, acpi_ps_parse_loop(). The function should have flush codes to
|
||||
handle an error state due to invalid AML codes.
|
||||
|
||||
This cache leak has a security threat because an old kernel (<= 4.9) shows
|
||||
memory locations of kernel functions in stack dump. Some malicious users
|
||||
could use this information to neutralize kernel ASLR.
|
||||
|
||||
To fix ACPI cache leak for enhancing security, I made a patch which has
|
||||
flush codes in acpi_ps_parse_loop() function.
|
||||
|
||||
I hope that this patch improves the security of Linux kernel.
|
||||
|
||||
Thank you.

Changes since v3: change control transfer according to reviewer's comments.
|
||||
Changes since v2: merge flush code with existing code and change comments.
|
||||
Changes since v1: move flush code to acpi_ps_complete_final_op() function.

|
||||
|
||||
I found an ACPI cache leak in ACPI early termination and boot continuing case.
|
||||
|
||||
When early termination is occurred due to malicious ACPI table, Linux kernel
|
||||
terminates ACPI function and continues to boot process. While kernel terminates
|
||||
ACPI function, kmem_cache_destroy() reports Acpi-Operand cache leak.
|
||||
|
||||
Boot log of ACPI operand cache leak is as follows:

|
||||
|
||||
I analyzed this memory leak in detail and found acpi_ds_obj_stack_pop_and_
|
||||
delete() function miscalculated the top of the stack. acpi_ds_obj_stack_push()
|
||||
function uses walk_state->operand_index for start position of the top, but
|
||||
acpi_ds_obj_stack_pop_and_delete() function considers index 0 for it.
|
||||
Therefore, this causes acpi operand memory leak.
|
||||
|
||||
This cache leak causes a security threat because an old kernel (<= 4.9) shows
|
||||
memory locations of kernel functions in stack dump. Some malicious users
|
||||
could use this information to neutralize kernel ASLR.
|
||||
|
||||
I made a patch to fix ACPI operand cache leak.

I analyzed this memory leak in detail and found acpi_ns_evaluate() function
|
||||
only removes info->return_object in AE_CTRL_RETURN_VALUE case. But, when errors
|
||||
occur, the status value is not AE_CTRL_RETURN_VALUE, and info->return_object is
|
||||
also not null. Therefore, this causes acpi operand memory leak.
|
||||
|
||||
This cache leak causes a security threat because an old kernel (<= 4.9) shows
|
||||
memory locations of kernel functions in stack dump. Some malicious users
|
||||
could use this information to neutralize kernel ASLR.
|
||||

||||

+ - allwinner,sun8i-h3-system-controller
|
||||
+ - allwinner,sun8i-v3s-system-controller
|
||||
+ - allwinner,sun50i-a64-system-controller
|
||||
+ - allwinner,sun8i-a83t-system-controller
|
||||
+
|
||||
+Optional properties:
|
||||
+- allwinner,tx-delay-ps: TX clock delay chain value in ps. Range value is 0-700. Default is 0)
|
||||
+- allwinner,rx-delay-ps: RX clock delay chain value in ps. Range value is 0-3100. Default is 0)
|
||||
+Both delay properties need to be a multiple of 100. They control the delay for
|
||||
+external PHY.
|
||||
+
|
||||
+Optional properties for the following compatibles:
|
||||
+ - "allwinner,sun8i-h3-emac",

+
|
||||
+Required child node of emac:
|
||||
+- mdio bus node: should be named mdio
|
||||
+
|
||||
+Required properties of the mdio node:
|
||||
+- #address-cells: shall be 1
|
||||
+- #size-cells: shall be 0
|
||||
+
|
||||
+The device node referenced by "phy" or "phy-handle" should be a child node
|
||||
+of the mdio node. See phy.txt for the generic PHY bindings.
|
||||
+
|
||||
+Required properties of the phy node with the following compatibles:

|
||||
Subject: of: restrict DMA configuration
|
||||
|
||||
Moving DMA configuration to happen later at driver probe time had the
|
||||
unnoticed side-effect that we now perform DMA configuration for *every*
|
||||
device represented in DT, rather than only those explicitly created by
|
||||
the of_platform and PCI code.
|
||||
|
||||
As Christoph points out, this is not really the best thing to do. Whilst
|
||||
there may well be other DMA-capable buses that can benefit from having
|
||||
their children automatically configured after the bridge has probed,
|
||||
there are also plenty of others like USB, MDIO, etc. that definitely do
|
||||
not support DMA and should not be indiscriminately processed.
|
||||
|
||||
The good news is that in most cases the DT "dma-ranges" property serves
|
||||
as an appropriate indicator - per a strict interpretation of the spec,
|
||||
anything lacking a "dma-ranges" property should be considered not to
|
||||
have a mapping of DMA address space from its children to its parent,
|
||||
thus anything for which of_dma_get_range() does not succeed does not
|
||||
need DMA configuration. Certain bus types have a general expectation of
|
||||
DMA capability and carry a well-established precedent that an absent
|
||||
"dma-ranges" implies the same as the empty property, so we automatically
|
||||
opt those in to DMA configuration regardless, to avoid regressing most
|
||||
existing platforms.

||||

This registers the host1x node with the SMMU (as HC swgroup) to allow
|
||||
the host1x code to attach to it. It avoid failing the probe sequence,
|
||||
which resulted in the tegra drm driver not probing and thus nothing
|
||||
being displayed on-screen.

Subject: [PATCH] ARM: dts: bcm283x: Add CPU thermal zone with 1
|
||||
trip point
|
||||
|
||||
As suggested by Eduardo Valentin this adds the thermal zone for
|
||||
the bcm2835 SoC with its single thermal sensor. We start with
|
||||
the criticial trip point and leave the cooling devices empty
|
||||
since we don't have any at the moment. Since the coefficients
|
||||
could vary depending on the SoC we need to define them separate.

We have multiple "earlycon" early_param handlers - merge the DT one into
|
||||
the main earlycon one. It's a cleanup that also will be useful
|
||||
to defer setting up DT console until ACPI/DT decision is made.

|

'ARM Server Base Boot Requiremets' [1] mentions SPCR (Serial Port
|
||||
Console Redirection Table) [2] as a mandatory ACPI table that
|
||||
specifies the configuration of serial console.
|
||||
|
||||
Defer initialization of DT earlycon until ACPI/DT decision is made.
|
||||
|
||||
Parse the ACPI SPCR table, setup earlycon if required,
|
||||
enable specified console.
|
||||
|
||||
Thanks to Peter Hurley for explaining how this should work.

|

|
||||
SBBR mentions SPCR as a mandatory ACPI table. So enable it for ARM64
|
||||
|
||||
Earlycon should be set up as early as possible. ACPI boot tables are
|
||||
mapped in arch/arm64/kernel/acpi.c:acpi_boot_table_init() that
|
||||
is called from setup_arch() and that's where we parse SPCR.
|
||||
So it has to be opted-in per-arch.
|
||||
|
||||
When ACPI_SPCR_TABLE is defined initialization of DT earlycon is
|
||||
deferred until the DT/ACPI decision is done. Initialize DT earlycon
|
||||
if ACPI is disabled.

This patch adds function pl011_console_match() that implements
|
||||
method match of struct console. It allows to match consoles against
|
||||
data specified in a string, for example taken from command line or
|
||||
compiled by ACPI SPCR table handler.

CFG resource calculation and ECAM ops assignment to pci_mcfg_lookup().
|

Subject: [PATCH 2/6] PCI/ACPI: Check platform specific ECAM quirks
|
||||
|
||||
Some platforms may not be fully compliant with generic set of PCI config
|
||||
accessors. For these cases we implement the way to overwrite CFG accessors
|
||||
set and configuration space range.
|
||||
|
||||
In first place pci_mcfg_parse() saves machine's IDs and revision number
|
||||
(these come from MCFG header) in order to match against known quirk entries.
|
||||
Then the algorithm traverses available quirk list (static array),
|
||||
matches against <oem_id, oem_table_id, rev, domain, bus number range> and
|
||||
returns custom PCI config ops and/or CFG resource structure.
|
||||
|
||||
When adding new quirk there are two possibilities:
|
||||
1. Override default pci_generic_ecam_ops ops but CFG resource comes from MCFG
|
||||
{ "OEM_ID", "OEM_TABLE_ID", <REV>, <DOMAIN>, <BUS_NR>, &foo_ops, MCFG_RES_EMPTY },
|
||||
2. Override default pci_generic_ecam_ops ops and CFG resource. For this case
|
||||
it is also allowed get CFG resource from quirk entry w/o having it in MCFG.
|
||||
{ "OEM_ID", "OEM_TABLE_ID", <REV>, <DOMAIN>, <BUS_NR>, &boo_ops,
|
||||
DEFINE_RES_MEM(START, SIZE) },
|
||||
|
||||
pci_generic_ecam_ops and MCFG entries will be used for platforms
|
||||
free from quirks.

Subject: [PATCH 3/6] PCI: thunder-pem: Allow to probe PEM-specific register
|
||||
range for ACPI case
|
||||
|
||||
thunder-pem driver stands for being ACPI based PCI host controller.
|
||||
However, there is no standard way to describe its PEM-specific register
|
||||
ranges in ACPI tables. Thus we add thunder_pem_init() ACPI extension
|
||||
to obtain hardcoded addresses from static resource array.
|
||||
Although it is not pretty, it prevents from creating standard mechanism to
|
||||
handle similar cases in future.

Subject: [PATCH 4/6] PCI: thunder: Enable ACPI PCI controller for ThunderX
|
||||
pass2.x silicon version
|
||||
|
||||
ThunderX PCIe controller to off-chip devices (so-called PEM) is not fully
|
||||
compliant with ECAM standard. It uses non-standard configuration space
|
||||
accessors (see pci_thunder_pem_ops) and custom configuration space granulation
|
||||
(see bus_shift = 24). In order to access configuration space and
|
||||
probe PEM as ACPI based PCI host controller we need to add MCFG quirk
|
||||
infrastructure. This involves:
|
||||
1. Export PEM pci_thunder_pem_ops structure so it is visible to MCFG quirk
|
||||
code.
|
||||
2. New quirk entries for each PEM segment. Each contains platform IDs,
|
||||
mentioned pci_thunder_pem_ops and CFG resources.
|
||||
|
||||
Quirk is considered for ThunderX silicon pass2.x only which is identified
|
||||
via MCFG revision 1.

|
||||
pass1.x silicon version
|
||||
|
||||
ThunderX pass1.x requires to emulate the EA headers for on-chip devices
|
||||
hence it has to use custom pci_thunder_ecam_ops for accessing PCI config
|
||||
space (pci-thuner-ecam.c). Add new entries to MCFG quirk array where they
|
||||
can be applied while probing ACPI based PCI host controller.
|
||||
|
||||
ThunderX pass1.x is using the same way for accessing off-chip devices
|
||||
(so-called PEM) as silicon pass-2.x so we need to add PEM quirk
|
||||
entries too.
|
||||
|
||||
Quirk is considered for ThunderX silicon pass1.x only which is identified
|
||||
via MCFG revision 2.

Subject: [PATCH 6/6] PCI/ACPI: xgene: Add ECAM quirk for X-Gene PCIe
|
||||
controller
|
||||
|
||||
PCIe controller in X-Gene SoCs is not ECAM compliant: software
|
||||
needs to configure additional concontroller register to address
|
||||
device at bus:dev:function.
|
||||
|
||||
This patch depends on "ECAM quirks handling for ARM64 platforms"
|
||||
series (http://www.spinics.net/lists/arm-kernel/msg530692.html)
|
||||
to address the limitation above for X-Gene PCIe controller.
|
||||
|
||||
The quirk will only be applied for X-Gene PCIe MCFG table with
|
||||
OEM revison 1, 2, 3 or 4 (PCIe controller v1 and v2 on X-Gene SoCs).

||||

Subject: ACPI: APEI: Enable APEI multiple GHES source to share a single
|
||||
external IRQ
|
||||
|
||||
X-Gene platforms describe multiple GHES error sources with the same
|
||||
hardware error notification type (external interrupt) and interrupt
|
||||
number.
|
||||
|
||||
Change the GHES interrupt request to support sharing the same IRQ.
|
||||
|
||||
This change includs contributions from Tuan Phan <tphan@apm.com>.

Subject: [PATCH 05/20] asus-wmi: Restrict debugfs interface when module
|
||||
loading is restricted
|
||||
|
||||
We have no way of validating what all of the Asus WMI methods do on a
|
||||
given machine, and there's a risk that some will allow hardware state to
|
||||
be manipulated in such a way that arbitrary code can be executed in the
|
||||
kernel, circumventing module loading restrictions. Prevent that if any of
|
||||
these features are enabled.
