scripts: Add a prettier version of autolocalversion
Enable CONFIG_LOCALVERSION_BRANCH_SHA if you want to see kernel version like this: 4.14.175-F1xy-Q-raphael/2a7e9d16cd - CONFIG_LOCALVERSION-branch name-commit sha. I had this in the build script for a few years but since there is a surge of ROMs using my kernel it's good to have this in the kernel code for the ease of tracking which version ROMs ship.

bpf: Add kconfig knob for disabling unpriv bpf by default
commit 08389d888287c3823f80b0216766b71e17f0aba5 upstream.
Add a kconfig knob which allows for unprivileged bpf to be disabled by default.
If set, the knob sets /proc/sys/kernel/unprivileged_bpf_disabled to value of 2.
This still allows a transition of 2 -> {0,1} through an admin. Similarly,
this also still keeps 1 -> {1} behavior intact, so that once set to permanently
disabled, it cannot be undone aside from a reboot.
We've also added extra2 with max of 2 for the procfs handler, so that an admin
still has a chance to toggle between 0 <-> 2.
Either way, as an additional alternative, applications can make use of CAP_BPF
that we added a while ago.

init/Kconfig: make COMPILE_TEST depend on HAS_IOMEM
commit ea29b20a828511de3348334e529a3d046a180416 upstream.
I read the commit log of the following two:
- bc083a64b6c0 ("init/Kconfig: make COMPILE_TEST depend on !UML")
- 334ef6ed06fa ("init/Kconfig: make COMPILE_TEST depend on !S390")
Both are talking about HAS_IOMEM dependency missing in many drivers.
So, 'depends on HAS_IOMEM' seems the direct, sensible solution to me.
This does not change the behavior of UML. UML still cannot enable
COMPILE_TEST because it does not provide HAS_IOMEM.
The current dependency for S390 is too strong. Under the condition of
CONFIG_PCI=y, S390 provides HAS_IOMEM, hence can enable COMPILE_TEST.
I also removed the meaningless 'default n'.

init/Kconfig: make COMPILE_TEST depend on !S390
commit 334ef6ed06fa1a54e35296b77b693bcf6d63ee9e upstream.
While allmodconfig and allyesconfig build for s390 there are also
various bots running compile tests with randconfig, where PCI is
disabled. This reveals that a lot of drivers should actually depend on
HAS_IOMEM.
Adding this to each device driver would be a never ending story,
therefore just disable COMPILE_TEST for s390.
The reasoning is more or less the same as described in
commit bc083a64b6c0 ("init/Kconfig: make COMPILE_TEST depend on !UML").

Stop the ad-hoc games with -Wno-maybe-initialized
commit 78a5255ffb6a1af189a83e493d916ba1c54d8c75 upstream. We have some rather random rules about when we accept the "maybe-initialized" warnings, and when we don't. For example, we consider it unreliable for gcc versions < 4.9, but also if -O3 is enabled, or if optimizing for size. And then various kernel config options disabled it, because they know that they trigger that warning by confusing gcc sufficiently (ie PROFILE_ALL_BRANCHES). And now gcc-10 seems to be introducing a lot of those warnings too, so it falls under the same heading as 4.9 did. At the same time, we have a very straightforward way to _enable_ that warning when wanted: use "W=2" to enable more warnings. So stop playing these ad-hoc games, and just disable that warning by default, with the known and straight-forward "if you want to work on the extra compiler warnings, use W=123". Would it be great to have code that is always so obvious that it never confuses the compiler whether a variable is used initialized or not? Yes, it would. In a perfect world, the compilers would be smarter, and our source code would be simpler. That's currently not the world we live in, though.

kbuild: compute false-positive -Wmaybe-uninitialized cases in Kconfig
commit b303c6df80c9f8f13785aa83a0471fca7e38b24d upstream.
Since -Wmaybe-uninitialized was introduced by GCC 4.7, we have patched
various false positives:
- commit e74fc973b6e5 ("Turn off -Wmaybe-uninitialized when building
with -Os") turned off this option for -Os.
- commit 815eb71e7149 ("Kbuild: disable 'maybe-uninitialized' warning
for CONFIG_PROFILE_ALL_BRANCHES") turned off this option for
CONFIG_PROFILE_ALL_BRANCHES
- commit a76bcf557ef4 ("Kbuild: enable -Wmaybe-uninitialized warning
for "make W=1"") turned off this option for GCC < 4.9
Arnd provided more explanation in https://lkml.org/lkml/2017/3/14/903
I think this looks better by shifting the logic from Makefile to Kconfig.

Extra added fixes in fs/f2fs/data.c for FBE:
* Fix FBE regression with 9937c21ce1 ("f2fs: add bio cache
for IPU"). The above commit is not setting the DUN for
bio, due to which the bio's could get corrupted when FBE
is enabled.
* The f2fs_merge_page_bio() incorrectly uses the bio after
it is submitted for IO when fscrypt_mergeable_bio()
returns false. Fix it by making the submitted bio NULL
so that a new bio gets allocated for the next/new page.

ANDROID: don't enable TOOLS_SUPPORT_RELR in all{mod,yes}config
We can't have this option enabled by default in all{mod,yes}config builds
because the tools might not support RELR. Follow the pattern used elsewhere
in the kernel and specify "depends on !COMPILE_TEST" in order to prevent it
from being turned on in these builds.

BACKPORT: arm64: Add support for relocating the kernel with RELR relocations
RELR is a relocation packing format for relative relocations. The format is described in a generic-abi proposal: https://groups.google.com/d/topic/generic-abi/bX460iggiKg/discussion The LLD linker can be instructed to pack relocations in the RELR format by passing the flag --pack-dyn-relocs=relr. This patch adds a new config option, CONFIG_RELR. Enabling this option instructs the linker to pack vmlinux's relative relocations in the RELR format, and causes the kernel to apply the relocations at startup along with the RELA relocations. RELA relocations still need to be applied because the linker will emit RELA relative relocations if they are unrepresentable in the RELR format (i.e. address not a multiple of 2). Enabling CONFIG_RELR reduces the size of a defconfig kernel image with CONFIG_RANDOMIZE_BASE by 3.5MB/16% uncompressed, or 550KB/5% compressed (lz4).

ANDROID: sched: Disallow WALT with CFS bandwidth control
The WALT time accounting breaks when CFS tasks are throttled by the CPU bandwidth control mechanism of the CPU cgroups controller. This can result in a negative cumulative_runnable_avg, which can then lead to a kernel panic, and the device crashing. Although the right fix would be add support for throttled CFS tasks to WALT, the common kernel is now in stable maintenance mode and will not get new features which could cause issues for partners downstream. To work around the issue, make the CFS_BANDWIDTH Kconfig option depend on SCHED_WALT=n, hence preventing these two things from being enabled simultaneously. This should not be an issue for most partners (nobody had noticed the breakage for years), and those who do need the better fix can apply it in their device kernel.

BACKPORT: Provide in-kernel headers to make extending kernel easier
Introduce in-kernel headers which are made available as an archive through proc (/proc/kheaders.tar.xz file). This archive makes it possible to run eBPF and other tracing programs that need to extend the kernel for tracing purposes without any dependency on the file system having headers. A github PR is sent for the corresponding BCC patch at: https://github.com/iovisor/bcc/pull/2312 On Android and embedded systems, it is common to switch kernels but not have kernel headers available on the file system. Further once a different kernel is booted, any headers stored on the file system will no longer be useful. This is an issue even well known to distros. By storing the headers as a compressed archive within the kernel, we can avoid these issues that have been a hindrance for a long time. The best way to use this feature is by building it in. Several users have a need for this, when they switch debug kernels, they do not want to update the filesystem or worry about it where to store the headers on it. However, the feature is also buildable as a module in case the user desires it not being part of the kernel image. This makes it possible to load and unload the headers from memory on demand. A tracing program can load the module, do its operations, and then unload the module to save kernel memory. The total memory needed is 3.3MB. By having the archive available at a fixed location independent of filesystem dependencies and conventions, all debugging tools can directly refer to the fixed location for the archive, without concerning with where the headers on a typical filesystem which significantly simplifies tooling that needs kernel headers. The code to read the headers is based on /proc/config.gz code and uses the same technique to embed the headers. Other approaches were discussed such as having an in-memory mountable filesystem, but that has drawbacks such as requiring an in-kernel xz decompressor which we don't have today, and requiring usage of 42 MB of kernel memory to host the decompressed headers at anytime. Also this approach is simpler than such approaches.

UPSTREAM: psi: clarify the Kconfig text for the default-disable option
The current help text caused some confusion in online forums about whether or not to default-enable or default-disable psi in vendor kernels. This is because it doesn't communicate the reason for why we made this setting configurable in the first place: that the overhead is non-zero in an artificial scheduler stress test. Since this isn't representative of real workloads, and the effect was not measurable in scheduler-heavy real world applications such as the webservers and memcache installations at Facebook, it's fair to point out that this is a pretty cautious option to select.

UPSTREAM: psi: make disabling/enabling easier for vendor kernels
Mel Gorman reports a hackbench regression with psi that would prohibit shipping the suse kernel with it default-enabled, but he'd still like users to be able to opt in at little to no cost to others. With the current combination of CONFIG_PSI and the psi_disabled bool set from the commandline, this is a challenge. Do the following things to make it easier: 1. Add a config option CONFIG_PSI_DEFAULT_DISABLED that allows distros to enable CONFIG_PSI in their kernel but leave the feature disabled unless a user requests it at boot-time. To avoid double negatives, rename psi_disabled= to psi=. 2. Make psi_disabled a static branch to eliminate any branch costs when the feature is disabled. In terms of numbers before and after this patch, Mel says: : The following is a comparision using CONFIG_PSI=n as a baseline against : your patch and a vanilla kernel : : 4.20.0-rc4 4.20.0-rc4 4.20.0-rc4 : kconfigdisable-v1r1 vanilla psidisable-v1r1 : Amean 1 1.3100 ( 0.00%) 1.3923 ( -6.28%) 1.3427 ( -2.49%) : Amean 3 3.8860 ( 0.00%) 4.1230 * -6.10%* 3.8860 ( -0.00%) : Amean 5 6.8847 ( 0.00%) 8.0390 * -16.77%* 6.7727 ( 1.63%) : Amean 7 9.9310 ( 0.00%) 10.8367 * -9.12%* 9.9910 ( -0.60%) : Amean 12 16.6577 ( 0.00%) 18.2363 * -9.48%* 17.1083 ( -2.71%) : Amean 18 26.5133 ( 0.00%) 27.8833 * -5.17%* 25.7663 ( 2.82%) : Amean 24 34.3003 ( 0.00%) 34.6830 ( -1.12%) 32.0450 ( 6.58%) : Amean 30 40.0063 ( 0.00%) 40.5800 ( -1.43%) 41.5087 ( -3.76%) : Amean 32 40.1407 ( 0.00%) 41.2273 ( -2.71%) 39.9417 ( 0.50%) : : It's showing that the vanilla kernel takes a hit (as the bisection : indicated it would) and that disabling PSI by default is reasonably : close in terms of performance for this particular workload on this : particular machine so; Link: http://lkml.kernel.org/r/20181127165329.GA29728@cmpxchg.org Signed-off-by: Johannes Weiner <hannes@cmpxchg.org> Tested-by: Mel Gorman <mgorman@techsingularity.net> Reported-by: Mel Gorman <mgorman@techsingularity.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> (cherry picked from commit e0c274472d5d27f277af722e017525e0b33784cd) Bug: 127712811 Test: lmkd in PSI mode Change-Id: I6cb666fa351e8901df82e4d6931bfec0c5ce230d Signed-off-by: Suren Baghdasaryan <surenb@google.com> |

BACKPORT: psi: cgroup support
On a system that executes multiple cgrouped jobs and independent workloads, we don't just care about the health of the overall system, but also that of individual jobs, so that we can ensure individual job health, fairness between jobs, or prioritize some jobs over others. This patch implements pressure stall tracking for cgroups. In kernels with CONFIG_PSI=y, cgroup2 groups will have cpu.pressure, memory.pressure, and io.pressure files that track aggregate pressure stall times for only the tasks inside the cgroup.

UPSTREAM: psi: pressure stall information for CPU, memory, and IO
When systems are overcommitted and resources become contended, it's hard
to tell exactly the impact this has on workload productivity, or how close
the system is to lockups and OOM kills. In particular, when machines work
multiple jobs concurrently, the impact of overcommit in terms of latency
and throughput on the individual job can be enormous.
In order to maximize hardware utilization without sacrificing individual
job health or risk complete machine lockups, this patch implements a way
to quantify resource pressure in the system.
A kernel built with CONFIG_PSI=y creates files in /proc/pressure/ that
expose the percentage of time the system is stalled on CPU, memory, or IO,
respectively. Stall states are aggregate versions of the per-task delay
accounting delays:
cpu: some tasks are runnable but not executing on a CPU
memory: tasks are reclaiming, or waiting for swapin or thrashing cache
io: tasks are waiting for io completions
These percentages of walltime can be thought of as pressure percentages,
and they give a general sense of system health and productivity loss
incurred by resource overcommit. They can also indicate when the system
is approaching lockup scenarios and OOMs.
To do this, psi keeps track of the task states associated with each CPU
and samples the time they spend in stall states. Every 2 seconds, the
samples are averaged across CPUs - weighted by the CPUs' non-idle time to
eliminate artifacts from unused CPUs - and translated into percentages of
walltime. A running average of those percentages is maintained over 10s,
1m, and 5m periods (similar to the loadaverage).

FROMLIST: sched/fair: add support to tune PELT ramp/decay timings
The PELT half-life is the time [ms] required by the PELT signal to build
up a 50% load/utilization, starting from zero. This time is currently
hardcoded to be 32ms, a value which seems to make sense for most of the
workloads.
However, 32ms has been verified to be too long for certain classes of
workloads. For example, in the mobile space many tasks affecting the
user-experience run with a 16ms or 8ms cadence, since they need to match
the common 60Hz or 120Hz refresh rate of the graphics pipeline.
This contributed so fare to the idea that "PELT is too slow" to properly
track the utilization of interactive mobile workloads, especially
compared to alternative load tracking solutions which provides a
better representation of tasks demand in the range of 10-20ms.
A faster PELT ramp-up time could give some advantages to speed-up the
time required for the signal to stabilize and thus to better represent
task demands in the mobile space. As a downside, it also reduces the
decay time, and thus we forget the load/utilization of sleeping tasks
(or idle CPUs) faster.
Fortunately, since the integration of the utilization estimation
support in mainline kernel:
commit 7f65ea42eb00 ("sched/fair: Add util_est on top of PELT")
a fast decay time is no longer an issue for tasks utilization estimation.
Although estimated utilization does not slow down the decay of blocked
utilization on idle CPUs, for mobile workloads this seems not to be a
major concern compared to the benefits in interactivity responsiveness.
Let's add a compile time option to choose the PELT speed which better
fits for a specific system. By default the current 32ms half-life is
used, but we can also compile a kernel to use a faster ramp-up time of
either 16ms or 8ms. These two configurations have been verified to give
PELT a further improvement in performance, compared to other out-of-tree
load tracking solutions, when it comes to track interactive workloads
thus better supporting both tasks placements and frequencies selections.

perf: Add support for user and kernel event sharing
The ARM PMU counters are limited in number. Even for counting similar events, the PMU driver allocates a new counter. Hence, counters configured to count similar events are shared. This was only possible for the kernel clients, but not for user-space clients. Hence, as an extension to this, the kernel and the user-space are now able to share the similar events. The counters can be shared between user-space only clients, kernel only clients, and among user-space and kernel clients. The kernel and user's attr->type (hardware/raw) and attr->config should be same for them to share the same counter.

bpf: introduce BPF_JIT_ALWAYS_ON config
[ upstream commit 290af86629b25ffd1ed6232c4e9107da031705cb ] The BPF interpreter has been used as part of the spectre 2 attack CVE-2017-5715. A quote from goolge project zero blog: "At this point, it would normally be necessary to locate gadgets in the host kernel code that can be used to actually leak data by reading from an attacker-controlled location, shifting and masking the result appropriately and then using the result of that as offset to an attacker-controlled address for a load. But piecing gadgets together and figuring out which ones work in a speculation context seems annoying. So instead, we decided to use the eBPF interpreter, which is built into the host kernel - while there is no legitimate way to invoke it from inside a VM, the presence of the code in the host kernel's text section is sufficient to make it usable for the attack, just like with ordinary ROP gadgets." To make attacker job harder introduce BPF_JIT_ALWAYS_ON config option that removes interpreter from the kernel in favor of JIT-only mode. So far eBPF JIT is supported by: x64, arm64, arm32, sparc64, s390, powerpc64, mips64 The start of JITed program is randomized and code page is marked as read-only. In addition "constant blinding" can be turned on with net.core.bpf_jit_harden v2->v3: - move __bpf_prog_ret0 under ifdef (Daniel) v1->v2: - fix init order, test_bpf and cBPF (Daniel's feedback) - fix offloaded bpf (Jakub's feedback) - add 'return 0' dummy in case something can invoke prog->bpf_func - retarget bpf tree. For bpf-next the patch would need one extra hunk. It will be sent when the trees are merged back to net-next Considered doing: int bpf_jit_enable __read_mostly = BPF_EBPF_JIT_DEFAULT; but it seems better to land the patch as-is and in bpf-next remove bpf_jit_enable global variable from all JITs, consolidate in one place and remove this jit_init() function.

ANDROID: sched: Introduce Window Assisted Load Tracking (WALT)
This patch is a combination of many many patches which have been previously applied to Android/EAS kernels. Similarly to other EAS components, we are squashing these to present a more orderly view of component history and relationships. The original description of WALT was: Use a window based view of time in order to track task demand and CPU utilization in the scheduler. WALT accounts two major statistics; CPU load and cumulative tasks demand. The CPU load which is account of accumulated each CPU's absolute execution time is for CPU frequency guidance. Whereas cumulative tasks demand which is each CPU's instantaneous load to reflect CPU's load at given time is for task placement decision. Use cumulative tasks demand for cpu_util() for task placement and introduce cpu_util_freq() for frequency guidance. This version includes the "cumulative window demand" statistic which was originally described as: Energy cost estimation has been a long lasting challenge for WALT because WALT guides CPU frequency based on the CPU utilization of previous window. Consequently it's not possible to know newly waking-up task's energy cost until WALT's end of the current window. The WALT already tracks 'Previous Runnable Sum' (prev_runnable_sum) and 'Cumulative Runnable Average' (cr_avg). They are designed for CPU frequency guidance and task placement but unfortunately both are not suitable for the energy cost estimation. It's because using prev_runnable_sum for energy cost calculation would make us to account CPU and task's energy solely based on activity in the previous window so for example, any task didn't have an activity in the previous window will be accounted as a 'zero energy cost' task. Energy estimation with cr_avg is what energy_diff() relies on at present. However cr_avg can only represent instantaneous picture of energy cost thus for example, if a CPU was fully occupied for an entire WALT window and became idle just before window boundary, and if there is a wake-up, energy_diff() accounts that CPU is a 'zero energy cost' CPU. As a result, introduce a new accounting unit 'Cumulative Window Demand'. The cumulative window demand tracks all the tasks' demands have seen in current window which is neither instantaneous nor actual execution time. Because task demand represents estimated scaled execution time when the task runs a full window, accumulation of all the demands represents predicted CPU load at the end of window. Thus we can estimate CPU's frequency at the end of current WALT window with the cumulative window demand. This version is extracted wholesale from the version currently available in android-4.4 and android-4.9.

ANDROID: sched: fair/tune: Add schedtune with cgroups interface
Schedtune is the framework we use in Android to allow userspace task classification and provides a CGroup controller which has two attributes per group. * schedtune.boost * schedtune.prefer_idle Schedtune itself provides task and CPU utilization boosting. EAS in the fair scheduler uses boosted utilization and prefer_idle status to control the algorithm used for wakeup task placement. Boosting: The task utilization signal, which is derived from PELT signals and properly scaled to be architecture and frequency invariant, is used by EAS as an estimation of the task requirements in terms of CPU bandwidth. Schedtune allows userspace to assign a percentage boost to each group and this boost is used to calculate an additional utilization margin. The margin added to the original utilization is: 1. computed based on the "boosting strategy" in use 2. proportional to boost value defined by the "taskgroup" value The boosted signal is used by EAS for task placement, and boosted CPU utilization (if boosted tasks are running) is given when schedutil requests utilization. Prefer_idle: When this attribute is 1 for a group, this is used as a signal from userspace that tasks in this group need to be serviced with the minimum latency possible. Previous versions of schedtune had much more functionality around allowing a more tuneable tradeoff between performand and energy, however this has not been used a lot up until now. If necessary, we can easily resurrect it based upon old code.
