UBUNTU: SAUCE: x86/quirks: Scan all busses for early PCI quirks
BugLink: https://bugs.launchpad.net/bugs/1797990
Recently was noticed in an HP GEN9 system that kdump couldn't succeed
due to an irq storm coming from an Intel NIC, narrowed down to be lack
of clearing the MSI/MSI-X enable bits during the kdump kernel boot.
For that, we need an early quirk to manually turn off MSI/MSI-X for
PCI devices - this was worked as an optional boot parameter in a
(~subsequent~) previous patch.
Problem is that in our test system, the Intel NICs were not present in
any secondary bus under the first PCIe root complex, so they couldn't
be reached by the recursion in check_dev_quirk(). Modern systems,
specially with multi-processors and multiple NUMA nodes expose multiple
root complexes, describing more than one PCI hierarchy domain. Currently
the simple recursion present in the early-quirks code from x86 starts a
descending recursion from bus 0000:00, and reach many other busses by
navigating this hierarchy walking through the bridges. This is not
enough in systems with more than one root complex/host bridge, since
the recursion won't "traverse" to other root complexes by starting
statically in 0000:00 (for more details, see [0]).
This patch hence implements the full bus/device/function scan in
early_quirks(), by checking all possible busses instead of using a
recursion based on the first root bus or limiting the search scope to
the first 32 busses (like it was done in the beginning [1]).
[1] From historical perspective, early PCI scan dates back
to BitKeeper, added by Andi Kleen's "[PATCH] APIC fixes for x86-64",
on October/2003. It initially restricted the search to the first
32 busses and slots.
Due to a potential bug found in Nvidia chipsets, the scan
was changed to run only in the first root bus: see
commit 8659c406ade3 ("x86: only scan the root bus in early PCI quirks")
Finally, secondary busses reachable from the 1st bus were re-added back by:
commit 850c321027c2 ("x86/quirks: Reintroduce scanning of secondary buses")

UBUNTU: SAUCE: x86/quirks: Add parameter to clear MSIs early on boot
BugLink: https://bugs.launchpad.net/bugs/1797990
We observed a kdump failure in x86 that was narrowed down to MSI irq
storm coming from a PCI network device. The bug manifests as a lack of
progress in the boot process of kdump kernel, and a flood of kernel
messages like:
[...]
[ 342.265294] do_IRQ: 0.155 No irq handler for vector
[ 342.266916] do_IRQ: 0.155 No irq handler for vector
[ 347.258422] do_IRQ: 14053260 callbacks suppressed
[...]
The root cause of the issue is that kexec process of the kdump kernel
doesn't ensure PCI devices are reset or MSI capabilities are disabled,
so a PCI adapter could produce a huge amount of irqs which would steal
all the processing time for the CPU (specially since we usually restrict
kdump kernel to use a single CPU only).
This patch implements the kernel parameter "pci=clearmsi" to clear the
MSI/MSI-X enable bits in the Message Control register for all PCI devices
during early boot time, thus preventing potential issues in the kexec'ed
kernel. PCI spec also supports/enforces this need (see PCI Local Bus
spec sections 6.8.1.3 and 6.8.2.3).

UBUNTU: SAUCE: cachefiles: Page leaking in cachefiles_read_backing_file while vmscan is active
BugLink: https://bugs.launchpad.net/bugs/1793430
[Description]
In a heavily loaded system where the system pagecache is nearing memory limits and fscache is enabled,
pages can be leaked by fscache while trying read pages from cachefiles backend.
This can happen because two applications can be reading same page from a single mount,
two threads can be trying to read the backing page at same time. This results in one of the thread
finding that a page for the backing file or netfs file is already in the radix tree. During the error
handling cachefiles does not cleanup the reference on backing page, leading to page leak.
[Fix]
The fix is straightforward, to decrement the reference when error is encounterd.
[Testing]
I have tested the fix using following method for 12+ hrs.
1) mkdir -p /mnt/nfs ; mount -o vers=3,fsc <server_ip>:/export /mnt/nfs
2) create 10000 files of 2.8MB in a NFS mount.
3) start a thread to simulate heavy VM presssure
(while true ; do echo 3 > /proc/sys/vm/drop_caches ; sleep 1 ; done)&
4) start multiple parallel reader for data set at same time
find /mnt/nfs -type f | xargs -P 80 cat > /dev/null &
find /mnt/nfs -type f | xargs -P 80 cat > /dev/null &
find /mnt/nfs -type f | xargs -P 80 cat > /dev/null &
..
..
find /mnt/nfs -type f | xargs -P 80 cat > /dev/null &
find /mnt/nfs -type f | xargs -P 80 cat > /dev/null &
5) finally check using cat /proc/fs/fscache/stats | grep -i pages ;
free -h , cat /proc/meminfo and page-types -r -b lru
to ensure all pages are freed.

UBUNTU: SAUCE: (namespace) block_dev: Forbid unprivileged mounting when device is opened for writing
For unprivileged mounts to be safe the user must not be able to

takes a step towards preventing this by refusing to mount in a
user namepspace if the block device is open for writing and
refusing attempts to open the block device for writing by non-
root while it is mounted in a user namespace.
To prevent this from happening we use i_writecount in the inodes
of the bdev filesystem similarly to how it is used for regular
files. Whenever the device is opened for writing i_writecount
is checked; if it is negative the open returns -EBUSY, otherwise
i_writecount is incremented. On mount, a positive i_writecount
results in mount_bdev returning -EBUSY, otherwise i_writecount
is decremented. Opens by root and mounts from init_user_ns do not
check nor modify i_writecount.

A new helper, projid_valid_eq(), is added to help with this.
- Update most capability checks to check for capabilities in

changes to the filesystem that a user in s_user_ns could
already make externally by virtue of having write access to

errors=panic, and this is made to require CAP_SYS_ADMIN in

done to verify that the user has access to the block device inode
at the specified path. In some cases it may be necessary to
check permissions towards the inode, such as allowing
unprivileged users to mount block devices in user namespaces.
Add an argument to lookup_bdev() to optionally perform this
permission check. A value of 0 skips the permission check and
behaves the same as before. A non-zero value specifies the mask
of access rights required towards the inode at the specified
path. The check is always skipped if the user has CAP_SYS_ADMIN.
All callers of lookup_bdev() currently pass a mask of 0, so this
patch results in no functional change. Subsequent patches will
add permission checks where appropriate.

UBUNTU: SAUCE: wcn36xx: read MAC from file or randomly generate one
BugLink: http://bugs.launchpad.net/bugs/1776491
By default, wcn36xx initializes itself with a dummy 00:00:00:00:00:00 MAC
address, preventing the interface from working until a valid MAC address was set.
While not an issue on Ubuntu Classic (where the user can always set it
later on the command line or via /etc/network/interfaces), it became a problem
on Ubuntu Core where the wifi interface is probed during installation,
before the user has any chance to set a new MAC address.
To overcome this scenario, the wcn36xx driver in Xenial had a couple of features:
1) during probe, if /lib/firmware/wlan/macaddr0 was present, its content was
used as the new MAC address
2) if that failed, a pseudo-random MAC addres was generated and set
and this is a port of a the corresponding Xenial code to Bionic:

drivers/net/wireless/ath/wcn36xx/wcn36xx-msm.c::wcn36xx_msm_get_hw_mac().

The adv7511 driver is currently woken up on successful EDID read
after a EDID_READY interrupt is triggered by the chip. If the driver
doesn't get the interrupt within 200 ms, its concluded that we failed
to read EDID from the monitor.
This interrupt doesn't seem to occur consistently in certain use cases
(for example, if we execute power-on -> get_modes -> power-off
repeatedly, this can be done by calling xrandr successively really
fast).
For now, execute the lesser preferred POLL path where the driver
manually checks on the interrupt status register after every 25ms.
We should ideally rootcause why we don't get EDID_READY interrupts
consistently instead of relying on the above approach.

UBUNTU: SAUCE: (snapdragon) drm/bridge/adv7511: Delay clearing of HPD interrupt status
BugLink: http://bugs.launchpad.net/bugs/1763040
When a hotplug event occurs, the adv7511 interrupt handler schedules
an hpd work after clearing the interrupt status registers
(ADV7511_REG_INT(x). The hpd work calls a drm helper that sends a
uevent to notify the userspace about the hotplug event.
On a hotplug connect, the userspace generally acts upon this uevent by
calling an ioctl (DRM_IOCTL_MODE_GETCONNECTOR) that probes on the
connector.This results in the connector's detect() drm_connector_func
being called. In the ADV7511 driver, this is a wrapper around the
adv7511_detect() call.
adv7511_detect() checks on the same interrupt ADV7511_REG_INT(0)
register which was previously cleared by the interrupt handler,
resulting in the func not realizing that a hotplug connect event
took place. ADV7511 loses its state when a disconnect happens, and
the driver needs to do a power-on to re-enable the hardware. This
fails to happen since calls to adv7511_detect() can fail to identify
that a hotplug connect took place.
Fix this by delaying the clearing of the ADV7511_INT0_HPD status flag.
Let the call to adv7511_hpd() be the only one responsible for clearing
this bitfield.
Note: Not sure if this is the best approach. Clearing a status flag
outside of the interrupt handler is generally looked down upon.

On some SoCs the Adaptive Voltage Scaling (AVS) technique is
employed to optimize the operating voltage of a device. At a
given frequency, the hardware monitors dynamic factors and either
makes a suggestion for how much to adjust a voltage for the
current frequency, or it automatically adjusts the voltage
without software intervention. Add an API to the OPP library for
the former case, so that AVS type devices can update the voltages
for an OPP when the hardware determines the voltage should
change. The assumption is that drivers like CPUfreq or devfreq
will register for the OPP notifiers and adjust the voltage
according to suggestions that AVS makes.

UBUNTU: SAUCE: (snapdragon) power: avs: Add support for CPR (Core Power Reduction)
BugLink: http://bugs.launchpad.net/bugs/1763040
CPR (Core Power Reduction) is a technology that reduces core
power on a CPU or other device. It reads voltage settings in
efuse from product test process as initial settings and populates
OPPs for the device being "monitored". Each OPP corresponds to a
"corner" that has a range of valid voltages for a particular
frequency. While the device is running at a particular frequency,
CPR monitors dynamic factors such as temperature, etc. and
adjusts the voltage for that frequency accordingly to save power
and meet silicon characteristic requirements.
This driver is based on work by others on codeaurora.org[1].
