From c8d1fff0f16ad906cca153a22faac11516ccc0dd Mon Sep 17 00:00:00 2001
From: Liu Chao <liuchao173@huawei.com>
Date: Mon, 18 Jul 2022 16:54:53 +0800
Subject: [PATCH] irqbalance-ui: skip ',' in parse_setup to avoid coredump
When processing the ',' in hex_to_bitmap, it returns '0000\ 0' directly.
The return value will be freed in parse_setup, but it is not requested
through malloc.
Fixes: 85d37098a551 ("Fix several memleak problems found by covscan")
And it treat ',' as "0000", which cause irqbalance-ui will display wrong
Banned CPU numbers.
For example:
# IRQBALANCE_BANNED_CPUS="00000002,00000000,00000000" ./irqbalance
or
# IRQBALANCE_BANNED_CPULIST="65" ./irqbalance
# ./irqbalance-ui
Banned CPU numbers: 73
Fixes: 76d1c9d73935 ("Add main user interface files")

Subject: [PATCH 03/13] thermal: Fix the warning message
The commit febe697ac321 ("change the log level in thermal.c from error to
warning") happens to insert an unneeded message: "thermald may not be
running."
This is not true because the events come from the kernel and Netlink has
the multicast subscription model. So it has nothing to do with thermald.

Subject: [PATCH 04/14] Prepare to handle thermal event
Intel's new hardware supports Hardware Feedback Interface to provide CPU
performance and energy efficiency information. Every update on this is
delivered via thermal event interrupt. The thermal framework in the Linux
kernel relays these notifications to userspace via a Netlink interface.
When a CPU's performance and efficiency are zero, irqbalance needs to mask
the CPU from interrupts. Introduce a new CPU mask to indicate banned CPUs
for this.
Before supporting this event handling, define functions. Their
implementation will be on the following patches.
This event is available only on x86-64 systems. And it can be subscribed
with help of Netlink libraries. So check them before building it.
Also add a new build option so users may opt out this support. Setting this
option on other systems will result in a build failure.

Subject: [PATCH 04/13] procinterrupts: Fix IRQ name parsing on certain arm64
SoC
On arm64 SoCs like TI's K3 SoC and few other SoCs, IRQ names don't get
parsed correct due to which they end up being classified into wrong
class. Fix this by considering last token to contain IRQ name always.
Eg.: /proc/interrupt
cat /proc/interrupts
CPU0 CPU1 CPU2 CPU3

14: 0 0 0 0 GICv3 23 Level arm-pmu

Subject: [PATCH 05/14] Implement Netlink helper functions to subscribe thermal
events
Establish Netlink socket connection in a nonblocking mode and callback
notification.
Tolerate a few times on failures from receiving events. In practice, such
delivery failure is rare. But it may indicate more fundamental issues if
it repeats. So disconnect it unless the failure is transient.
Event-specific handler will be implemented in the next patch.

Subject: [PATCH 06/14] Handle thermal events to mask CPUs
The Hardware Feedback Interface event is delivered as the Netlink's
THERMAL_GENL_ATTR_CPU_CAPABILITY attribute. Add code to receive and parse
these attributes: logical CPU number, performance, and efficiency
enumeration values (0-1023).
When an event indicates CPU performance and efficiency are zeros, then the
CPU needs to be banned from IRQs. Rebuild object tree to make this banned
list effective.
Creating the banned CPU list here is a bit tricky here because the amount
of data that each Netlink notification can carry out is not enough in some
systems with many cores. This means the handler has to wait for multiple
notifications to determine banned CPUs per thermal event.
Establish a logic to maintain the list based on the kernel behaviors. Also,
always push the current list as of the banned CPUs, because there is no
clear line whether each notification is at the end of a thermal event or
not.

Subject: [PATCH 06/13] ui: do not force black background
Avoid repainting the entire terminal window with black background.
Instead, invoke 'use_default_colors' and use color index -1 to keep
user-configured background and foreground colors.
For pairs 1, 2, 3, 8, 9, 10, simply change background index to -1.
Keep pair 4, but enable the 'bold' attribute for text to improve
legibility. For pair 5 (white on red) use default foreground, and
instead of pair 6 (red on white) use reverse of pair 5 with bold.
This substantially improves legibility of the UI on a terminal
configured with a light background for me.

Subject: [PATCH 13/13] procinterrupts: fix initialisation of regex_t struct
{NULL} utilises the null pointer, but this is not valid, because null is a pointer:
procinterrupts.c:110:29: error: initialization of 'long unsigned int' from 'void *' makes integer from pointer without a cast [-Werror=int-conversion]
110 | { "eth.*" ,{NULL} ,NULL, IRQ_TYPE_LEGACY, IRQ_GBETH },
0-initialisation should be done with '0' instead of a pointer.
