In commit dc3890441c ("drm/virtio: Set segment size for virtio_gpu
device"), dma_max_mapping_size() is added to the virtio-gpu driver, but
it was not exported, so export it now to allow the driver to build
properly.
Fixes: dc3890441c ("drm/virtio: Set segment size for virtio_gpu device")

In the 6.1.79 merge, the msm.ko module now needs to use the
pm_runtime_get_if_active symbol for the db845 target, so properly add it
to the symbol list so that the build will work properly.
Fixes: ff43d92a56 ("Merge 6.1.79 into android14-6.1-lts")

We need the abi updates to be merged to the -lts branch so we can
properly track the new symbols. This includes the following commit:
089d1b8f6d ANDROID: Add known structs used by modules to KMI
Change-Id: Ie1915aedf85ab42761c27cfb63283be675f11c86
Signed-off-by: Greg Kroah-Hartman <gregkh@google.com>
This adds `struct dwc3` and `struct kernel_all_info` to the KMI via fake
GKI symbols as we know some partners are using these in their
out-of-tree drivers. This ensures that future changes to these structs
will not break partner builds.

commit 5ec8e8ea8b7783fab150cf86404fc38cb4db8800 upstream.
It breaks the Android kernel abi and can be brought back in the future
in an abi-safe way if it is really needed.

commit 0d459e2ffb541841714839e8228b845458ed3b27 upstream.
The commit mutex should not be released during the critical section
between nft_gc_seq_begin() and nft_gc_seq_end(), otherwise, async GC
worker could collect expired objects and get the released commit lock
within the same GC sequence.
nf_tables_module_autoload() temporarily releases the mutex to load
module dependencies, then it goes back to replay the transaction again.
Move it at the end of the abort phase after nft_gc_seq_end() is called.

commit a45e6889575c2067d3c0212b6bc1022891e65b91 upstream.
Unlike early commit path stage which triggers a call to abort, an
explicit release of the batch is required on abort, otherwise mutex is
released and commit_list remains in place.
Add WARN_ON_ONCE to ensure commit_list is empty from the abort path
before releasing the mutex.
After this patch, commit_list is always assumed to be empty before
grabbing the mutex, therefore
03c1f1ef15 ("netfilter: Cleanup nft_net->module_list from nf_tables_exit_net()")
only needs to release the pending modules for registration.

commit 552705a3650bbf46a22b1adedc1b04181490fc36 upstream.
While the rhashtable set gc runs asynchronously, a race allows it to
collect elements from anonymous sets with timeouts while it is being
released from the commit path.
Mingi Cho originally reported this issue in a different path in 6.1.x
with a pipapo set with low timeouts which is not possible upstream since
7395dfacfff6 ("netfilter: nf_tables: use timestamp to check for set
element timeout").
Fix this by setting on the dead flag for anonymous sets to skip async gc
in this case.
According to 08e4c8c5919f ("netfilter: nf_tables: mark newset as dead on
transaction abort"), Florian plans to accelerate abort path by releasing
objects via workqueue, therefore, this sets on the dead flag for abort

Offlining a CPU and bringing it back online is a common operation and it
happens frequently during system suspend/resume, where the non-boot CPUs
are hotplugged out during suspend and brought back at resume.
The cpufreq core already tries to make this path as fast as possible as
the changes are only temporary in nature and full cleanup of resources
isn't required in this case. For example the drivers can implement
online()/offline() callbacks to avoid a lot of tear down of resources.
On similar lines, there is no need to unregister the cpufreq cooling
device during suspend / resume, but only while the policy is getting
removed.
Moreover, unregistering the cpufreq cooling device is resulting in an
unwanted outcome, where the system suspend is eventually aborted in the
process. Currently, during system suspend the cpufreq core unregisters
the cooling device, which in turn removes a kobject using device_del()
and that generates a notification to the userspace via uevent broadcast.
This causes system suspend to abort in some setups.
This was also earlier reported (indirectly) by Roman [1]. Maybe there is
another way around to fixing that problem properly, but this change
makes sense anyways.
Move the registering and unregistering of the cooling device to policy
creation and removal times onlyy.

Signed-off-by: John Stultz <jstultz@google.com>
Bug: 333300519
Off-by-one errors happen because nr_snk_pdo and nr_src_pdo are
incorrectly added one. The index of the loop is equal to the number of
PDOs to be updated when leaving the loop and it doesn't need to be added
one.
When doing the power negotiation, TCPM relies on the "nr_snk_pdo" as
the size of the local sink PDO array to match the Source capabilities
of the partner port. If the off-by-one overflow occurs, a wrong RDO
might be sent and unexpected power transfer might happen such as over
voltage or over current (than expected).
"nr_src_pdo" is used to set the Rp level when the port is in Source
role. It is also the array size of the local Source capabilities when
filling up the buffer which will be sent as the Source PDOs (such as
in Power Negotiation). If the off-by-one overflow occurs, a wrong Rp
level might be set and wrong Source PDOs will be sent to the partner
port. This could potentially cause over current or port resets.

The current implementation of the mark_victim tracepoint provides only the
process ID (pid) of the victim process. This limitation poses challenges
for userspace tools requiring real-time OOM analysis and intervention.
Although this information is available from the kernel logs, it’s not
the appropriate format to provide OOM notifications. In Android, BPF
programs are used with the mark_victim trace events to notify userspace of
an OOM kill. For consistency, update the trace event to include the same
information about the OOMed victim as the kernel logs.
- UID
In Android each installed application has a unique UID. Including
the `uid` assists in correlating OOM events with specific apps.
- Process Name (comm)
Enables identification of the affected process.
- OOM Score
Will allow userspace to get additional insight of the relative kill
priority of the OOM victim. In Android, the oom_score_adj is used to
categorize app state (foreground, background, etc.), which aids in
analyzing user-perceptible impacts of OOM events [1].
- Total VM, RSS Stats, and pgtables
Amount of memory used by the victim that will, potentially, be freed up
by killing it.

virtsnd_kctl_tlv_op() only with values for op_flag processed in

Implementation of support for audio controls in accordance with the
extension of the virtio sound device specification [1] planned for
virtio-v1.3-cs01.
The device can announce the VIRTIO_SND_F_CTLS feature. If the feature is
negotiated, then an additional field appears in the configuration space:
struct virtio_snd_config {
...
/* number of available control elements */
__le32 controls;
};
The driver can send the following requests to manage audio controls:
enum {
...
/* control element request types */
VIRTIO_SND_R_CTL_INFO = 0x0300,
VIRTIO_SND_R_CTL_ENUM_ITEMS,
VIRTIO_SND_R_CTL_READ,
VIRTIO_SND_R_CTL_WRITE,
VIRTIO_SND_R_CTL_TLV_READ,
VIRTIO_SND_R_CTL_TLV_WRITE,
VIRTIO_SND_R_CTL_TLV_COMMAND,
...
};
And the device can send the following audio control event notification:
enum {
...
/* control element event types */
VIRTIO_SND_EVT_CTL_NOTIFY = 0x1200,
...
};
See additional details in [1].

__alloc_pages_direct_reclaim() is called from slowpath allocation where
high atomic reserves can be unreserved after there is a progress in
reclaim and yet no suitable page is found. Later should_reclaim_retry()
gets called from slow path allocation to decide if the reclaim needs to be
retried before OOM kill path is taken.
should_reclaim_retry() checks the available(reclaimable + free pages)
memory against the min wmark levels of a zone and returns:
a) true, if it is above the min wmark so that slow path allocation will
do the reclaim retries.
b) false, thus slowpath allocation takes oom kill path.
should_reclaim_retry() can also unreserves the high atomic reserves **but
only after all the reclaim retries are exhausted.**
In a case where there are almost none reclaimable memory and free pages
contains mostly the high atomic reserves but allocation context can't use
these high atomic reserves, makes the available memory below min wmark
levels hence false is returned from should_reclaim_retry() leading the
allocation request to take OOM kill path. This can turn into a early oom
kill if high atomic reserves are holding lot of free memory and
unreserving of them is not attempted.
(early)OOM is encountered on a VM with the below state:

Per above log, the free memory of ~7MB exist in the high atomic reserves
is not freed up before falling back to oom kill path.
Fix it by trying to unreserve the high atomic reserves in
should_reclaim_retry() before __alloc_pages_direct_reclaim() can fallback
to oom kill path.

Highatomic reserves are set to roughly 1% of zone for maximum and a
pageblock size for minimum. Encountered a system with the below
configuration:
Normal free:7728kB boost:0kB min:804kB low:1004kB high:1204kB
reserved_highatomic:8192KB managed:49224kB
On such systems, even a single pageblock makes highatomic reserves are set
to ~8% of the zone memory. This high value can easily exert pressure on
the zone.
Per discussion with Michal and Mel, it is not much useful to reserve the
memory for highatomic allocations on such small systems[1]. Since the
minimum size for high atomic reserves is always going to be a pageblock
size and if 1% of zone managed pages is going to be below pageblock size,
don't reserve memory for high atomic allocations. Thanks Michal for this
suggestion[2].
Since no memory is being reserved for high atomic allocations and if
respective allocation failures are seen, this patch can be reverted.

caluculations", v3.
The state of the system where the issue exposed shown in oom kill logs:

[ 295.998659] Normal: 508*4kB (UMEH) 241*8kB (UMEH) 143*16kB (UMEH)

From the above, it is seen that ~16MB of memory reserved for high atomic
reserves against the expectation of 1% reserves which is fixed in the 1st
patch.
Don't reserve the high atomic page blocks if 1% of zone memory size is
below a pageblock size.
This patch (of 2):
reserve_highatomic_pageblock() aims to reserve the 1% of the managed pages
of a zone, which is used for the high order atomic allocations.
It uses the below calculation to reserve:
static void reserve_highatomic_pageblock(struct page *page, ....) {
.......
max_managed = (zone_managed_pages(zone) / 100) + pageblock_nr_pages;
if (zone->nr_reserved_highatomic >= max_managed)
goto out;
zone->nr_reserved_highatomic += pageblock_nr_pages;
set_pageblock_migratetype(page, MIGRATE_HIGHATOMIC);
move_freepages_block(zone, page, MIGRATE_HIGHATOMIC, NULL);
out:
....
}
Since we are always appending the 1% of zone managed pages count to
pageblock_nr_pages, the minimum it is turning into 2 pageblocks as the
nr_reserved_highatomic is incremented/decremented in pageblock sizes.
Encountered a system(actually a VM running on the Linux kernel) with the
below zone configuration:
Normal free:7728kB boost:0kB min:804kB low:1004kB high:1204kB
reserved_highatomic:8192KB managed:49224kB
The existing calculations making it to reserve the 8MB(with pageblock size
of 4MB) i.e. 16% of the zone managed memory. Reserving such high amount
of memory can easily exert memory pressure in the system thus may lead
into unnecessary reclaims till unreserving of high atomic reserves.
Since high atomic reserves are managed in pageblock size granules, as
MIGRATE_HIGHATOMIC is set for such pageblock, fix the calculations for
high atomic reserves as, minimum is pageblock size , maximum is
approximately 1% of the zone managed pages.
