Revert "pstore: migrate to crypto acomp interface"
When using this new interface, both efi_pstore and ramoops
backends are unable to properly decompress dmesg if using
zstd, lz4 and lzo algorithms (and maybe more). It does succeed
with deflate though.
The message observed in the kernel log is:
[2.328828] pstore: crypto_acomp_decompress failed, ret = -22!
The pstore infrastructure is able to collect the dmesg with
both backends tested, but since decompression fails it's
unreadable. With this revert everything is back to normal.

drm/amd/display: Prevent OTG shutdown during PSR SU
[Why]
Enabling Z10 optimizations allows DMUB to disable the OTG during PSR
link-off. This theoretically saves power by putting more of the display
hardware to sleep. However, we observe that with PSR SU, it causes
visual artifacts, higher power usage, and potential system hang.
This is partly due to an odd behavior with the VStartup interrupt used
to signal DRM vblank events. If the OTG is toggled on/off during a PSR
link on/off cycle, the vstartup interrupt fires twice in quick
succession. This generates incorrectly timed vblank events.
Additionally, it can cause cursor updates to generate visual artifacts.
Note that this is not observed with PSR1 since PSR is fully disabled
when there are vblank event requestors. Cursor updates are also
artifact-free, likely because there are no selectively-updated (SU)
frames that can generate artifacts.
[How]
A potential solution is to disable z10 idle optimizations only when fast
updates (flips & cursor updates) are committed. A mechanism to do so
would require some thoughtful design. Let's just disable idle
optimizations for PSR2 for now.

The mptcp socket and its subflow sockets in accept queue can't be
released after the process exit.
While the release of a mptcp socket in listening state, the
corresponding tcp socket will be released too. Meanwhile, the tcp
socket in the unaccept queue will be released too. However, only init
subflow is in the unaccept queue, and the joined subflow is not in the
unaccept queue, which makes the joined subflow won't be released, and
therefore the corresponding unaccepted mptcp socket will not be released
to.
This can be reproduced easily with following steps:
1. create 2 namespace and veth:
$ ip netns add mptcp-client
$ ip netns add mptcp-server
$ sysctl -w net.ipv4.conf.all.rp_filter=0
$ ip netns exec mptcp-client sysctl -w net.mptcp.enabled=1
$ ip netns exec mptcp-server sysctl -w net.mptcp.enabled=1
$ ip link add red-client netns mptcp-client type veth peer red-server \
netns mptcp-server
$ ip -n mptcp-server address add 10.0.0.1/24 dev red-server
$ ip -n mptcp-server address add 192.168.0.1/24 dev red-server
$ ip -n mptcp-client address add 10.0.0.2/24 dev red-client
$ ip -n mptcp-client address add 192.168.0.2/24 dev red-client
$ ip -n mptcp-server link set red-server up
$ ip -n mptcp-client link set red-client up
2. configure the endpoint and limit for client and server:
$ ip -n mptcp-server mptcp endpoint flush
$ ip -n mptcp-server mptcp limits set subflow 2 add_addr_accepted 2
$ ip -n mptcp-client mptcp endpoint flush
$ ip -n mptcp-client mptcp limits set subflow 2 add_addr_accepted 2
$ ip -n mptcp-client mptcp endpoint add 192.168.0.2 dev red-client id \
1 subflow
3. listen and accept on a port, such as 9999. The nc command we used
here is modified, which makes it use mptcp protocol by default.
$ ip netns exec mptcp-server nc -l -k -p 9999
4. open another *two* terminal and use each of them to connect to the
server with the following command:
$ ip netns exec mptcp-client nc 10.0.0.1 9999
Input something after connect to trigger the connection of the second
subflow. So that there are two established mptcp connections, with the
second one still unaccepted.
5. exit all the nc command, and check the tcp socket in server namespace.
And you will find that there is one tcp socket in CLOSE_WAIT state
and can't release forever.
Fix this by closing all of the unaccepted mptcp socket in
mptcp_subflow_queue_clean() with __mptcp_close().
Now, we can ensure that all unaccepted mptcp sockets will be cleaned by
__mptcp_close() before they are released, so mptcp_sock_destruct(), which
is used to clean the unaccepted mptcp socket, is not needed anymore.
The selftests for mptcp is ran for this commit, and no new failures.

net: mscc: ocelot: fix tagged VLAN refusal while under a VLAN-unaware bridge
Currently the following set of commands fails:
$ ip link add br0 type bridge # vlan_filtering 0
$ ip link set swp0 master br0
$ bridge vlan
port vlan-id
swp0 1 PVID Egress Untagged
$ bridge vlan add dev swp0 vid 10
Error: mscc_ocelot_switch_lib: Port with more than one egress-untagged VLAN cannot have egress-tagged VLANs.
Dumping ocelot->vlans, one can see that the 2 egress-untagged VLANs on swp0 are
vid 1 (the bridge PVID) and vid 4094, a PVID used privately by the driver for
VLAN-unaware bridging. So this is why bridge vid 10 is refused, despite
'bridge vlan' showing a single egress untagged VLAN.
As mentioned in the comment added, having this private VLAN does not impose
restrictions to the hardware configuration, yet it is a bookkeeping problem.
There are 2 possible solutions.
One is to make the functions that operate on VLAN-unaware pvids:
- ocelot_add_vlan_unaware_pvid()
- ocelot_del_vlan_unaware_pvid()
- ocelot_port_setup_dsa_8021q_cpu()
- ocelot_port_teardown_dsa_8021q_cpu()
call something different than ocelot_vlan_member_(add|del)(), the latter being
the real problem, because it allocates a struct ocelot_bridge_vlan *vlan which
it adds to ocelot->vlans. We don't really *need* the private VLANs in
ocelot->vlans, it's just that we have the extra convenience of having the
vlan->portmask cached in software (whereas without these structures, we'd have
to create a raw ocelot_vlant_rmw_mask() procedure which reads back the current
port mask from hardware).
The other solution is to filter out the private VLANs from
ocelot_port_num_untagged_vlans(), since they aren't what callers care about.
We only need to do this to the mentioned function and not to
ocelot_port_num_tagged_vlans(), because private VLANs are never egress-tagged.
Nothing else seems to be broken in either solution, but the first one requires
more rework which will conflict with the net-next change 36a0bf443585 ("net:
mscc: ocelot: set up tag_8021q CPU ports independent of user port affinity"),
and I'd like to avoid that. So go with the other one.

drm/amdgpu: Add amdgpu suspend-resume code path under SRIOV
- Under SRIOV, we need to send REQ_GPU_FINI to the hypervisor
during the suspend time. Furthermore, we cannot request a
mode 1 reset under SRIOV as VF. Therefore, we will skip it
as it is called in suspend_noirq() function.
- In the resume code path, we need to send REQ_GPU_INIT to the
hypervisor and also resume PSP IP block under SRIOV.

For individual feature testing, PMFW may not report all clock

[How]
Add helper function to scan through initial clock values and

AF_XDP Tx descriptor cleaning in ice driver currently works in a "lazy"
way - descriptors are not cleaned immediately after send. We rather hold
on with cleaning until we see that free space in ring drops below
particular threshold. This was supposed to reduce the amount of
unnecessary work related to cleaning and instead of keeping the ring
empty, ring was rather saturated.
In AF_XDP realm cleaning Tx descriptors implies producing them to CQ.
This is a way of letting know user space that particular descriptor has
been sent, as John points out in [0].
We tried to implement serial descriptor cleaning which would be used in
conjunction with batched cleaning but it made code base more convoluted
and probably harder to maintain in future. Therefore we step away from
batched cleaning in a current form in favor of an approach where we set
RS bit on every last descriptor from a batch and clean always at the
beginning of ice_xmit_zc().
This means that we give up a bit of Tx performance, but this doesn't
hurt l2fwd scenario which is way more meaningful than txonly as this can
be treaten as AF_XDP based packet generator. l2fwd is not hurt due to
the fact that Tx side is much faster than Rx and Rx is the one that has
to catch Tx up.
FWIW Tx descriptors are still produced in a batched way.

Commit 46701d26816e ("net: phy: Don't WARN for PHY_READY state in

It turns out PHY_UP state needs to be exempted as well because the

phy_stop_machine()
phydev->state = PHY_UP # if (phydev->state >= PHY_UP)
The issue is related with serdes which impacts clock. There is
serdes in ADLink I-Pi SMARC board ethernet controller. Please refer to
commit 07d3f386ff92a0 ("net: stmmac: Enable SERDES power up/down sequence")
for detial. When issue is reproduced, DMA engine clock is not ready
because serdes is not powered up.
To reproduce DMA engine reset timeout issue with hardware which has
serdes in GBE controller, install Ubuntu. In Ubuntu GUI, click
"Power Off/Log Out" -> "Suspend" menu, it disables network interface,
then goes to sleep mode. When it wakes up, it enables network
interface again. Stmmac driver is called in this way:
1. stmmac_release: Stop network interface. In this function, it
disables DMA engine and network interface;
2. stmmac_suspend: It is called in kernel suspend flow. But because
network interface has been disabled(netif_running(ndev) is
false), it does nothing and returns directly;
3. System goes into S3 or S0ix state. Some time later, system is
waken up by keyboard or mouse;
4. stmmac_resume: It does nothing because network interface has
been disabled;
5. stmmac_open: It is called to enable network interace again. DMA
engine is initialized in this API, but serdes is not power on so
there will be DMA engine reset timeout issue.
Similarly, serdes powerdown should be added in stmmac_release.
Network interface might be disabled by cmd "ifconfig eth0 down",
DMA engine, phy and mac have been disabled in ndo_stop callback,
serdes should be powered down as well. It doesn't make sense that
serdes is on while other components have been turned off.
If ethernet interface is in enabled state(netif_running(ndev) is true)
before suspend/resume, the issue couldn't be reproduced because serdes
could be powered up in stmmac_resume.
Because serdes_powerup is added in stmmac_open, it doesn't need to be
called in probe function.

Specifically this is a problem for ralink rt2500-pci cards where

Other callers of __ieee80211_select_queue() skip calling it when

Make sure local->queue_stop_reasons and vif.txqs_stopped stay in sync.
When a new vif is created the queues may end up in an inconsistent state

Communication not using iTXQ will work, allowing to e.g. complete the
association. But the 4-way handshake will time out. The sta will not
send out any skbs queued in iTXQs.
All normal attempts to start the queues will fail when reaching this

local->queue_stop_reasons will have marked all queues as operational but
vif.txqs_stopped will still be set, creating an inconsistent internal

In reality this seems to be race between the mac80211 function

There are at least two ways to get a deadlock:
1) When we have a TDLS teardown packet queued in either tin or frags
ieee80211_tdls_td_tx_handle() will call ieee80211_subif_start_xmit()

deadlock.
2) A variant of the above happens if aggregation is up and running:
In that case ieee80211_iface_work() will deadlock with the original

sta->lock after kicking off ieee80211_iface_work(). But the worker

libata: add ATA_HORKAGE_NOLPM for Pioneer BDR-207M and BDR-205
Commit d026345f2169 ("ata: ahci: Add Green Sardine vendor ID as
board_ahci_mobile") added an explicit entry for AMD Green Sardine
AHCI controller using the board_ahci_mobile configuration (this
configuration has later been renamed to board_ahci_low_power).
The board_ahci_low_power configuration enables support for low power
modes.
This explicit entry takes precedence over the generic AHCI controller
entry, which does not enable support for low power modes.
Therefore, when commit d026345f2169 ("ata: ahci: Add Green Sardine
vendor ID as board_ahci_mobile") was backported to stable kernels,
it make some Pioneer optical drives, which was working perfectly fine
before the commit was backported, stop working.
The real problem is that the Pioneer optical drives do not handle low
power modes correctly. If these optical drives would have been tested
on another AHCI controller using the board_ahci_low_power configuration,
this issue would have been detected earlier.
Unfortunately, the board_ahci_low_power configuration is only used in
less than 15% of the total AHCI controller entries, so many devices
have never been tested with an AHCI controller with low power modes.

A recent change affecting the behaviour of phys_to_dma() to
actually require the device tree ranges to work unmasked a
bug in the Integrator DMA ranges.
The PL110 uses the CMA allocator to obtain coherent allocations
from a dedicated 1MB video memory, leading to the following
call chain:
phys_to_dma() by way of translate_phys_to_dma() will nowadays not
provide 1:1 mappings unless the ranges are properly defined in
the device tree and reflected into the dev->dma_range_map.
There is a bug in the device trees because the DMA ranges are
incorrectly specified, and the patch uncovers this bug.
Solution:
- Fix the LB (logic bus) ranges to be 1-to-1 like they should
have always been.
- Provide a 1:1 dma-ranges attribute to the PL110.
- Mark the PL110 display controller as DMA coherent.
This makes the DMA ranges work right and makes the PL110
framebuffer work again.

x86/uaccess: avoid check_object_size() in copy_from_user_nmi()
The check_object_size() helper under CONFIG_HARDENED_USERCOPY is designed
to skip any checks where the length is known at compile time as a
reasonable heuristic to avoid "likely known-good" cases. However, it can
only do this when the copy_*_user() helpers are, themselves, inline too.
Using find_vmap_area() requires taking a spinlock. The
check_object_size() helper can call find_vmap_area() when the destination
is in vmap memory. If show_regs() is called in interrupt context, it will
attempt a call to copy_from_user_nmi(), which may call check_object_size()
and then find_vmap_area(). If something in normal context happens to be
in the middle of calling find_vmap_area() (with the spinlock held), the
interrupt handler will hang forever.
The copy_from_user_nmi() call is actually being called with a fixed-size
length, so check_object_size() should never have been called in the first
place. Given the narrow constraints, just replace the
__copy_from_user_inatomic() call with an open-coded version that calls
only into the sanitizers and not check_object_size(), followed by a call
to raw_copy_from_user().

set_migratetype_isolate() does not allow isolating MIGRATE_CMA pageblocks
unless it is used for CMA allocation. isolate_single_pageblock() did not
have the same behavior when it is used together with
set_migratetype_isolate() in start_isolate_page_range(). This allows
alloc_contig_range() with migratetype other than MIGRATE_CMA, like
MIGRATE_MOVABLE (used by alloc_contig_pages()), to isolate first and last
pageblock but fail the rest. The failure leads to changing migratetype of
the first and last pageblock to MIGRATE_MOVABLE from MIGRATE_CMA,
corrupting the CMA region. This can happen during gigantic page
allocations.
Like Doug said here:
https://lore.kernel.org/linux-mm/a3363a52-883b-dcd1-b77f-f2bb378d6f2d@gmail.com/T/#u,
for gigantic page allocations, the user would notice no difference,
since the allocation on CMA region will fail as well as it did before.
But it might hurt the performance of device drivers that use CMA, since
CMA region size decreases.
Fix it by passing migratetype into isolate_single_pageblock(), so that
set_migratetype_isolate() used by isolate_single_pageblock() will prevent
the isolation happening.

mm,hwpoison: check mm when killing accessing process
The GHES code calls memory_failure_queue() from IRQ context to queue work
into workqueue and schedule it on the current CPU. Then the work is
processed in memory_failure_work_func() by kworker and calls
memory_failure().
When a page is already poisoned, commit cb847afd775e ("mm,hwpoison: send
SIGBUS with error virutal address") make memory_failure() call
kill_accessing_process() that:
- holds mmap locking of current->mm
- does pagetable walk to find the error virtual address
- and sends SIGBUS to the current process with error info.
However, the mm of kworker is not valid, resulting in a null-pointer
dereference. So check mm when killing the accessing process.

mm: prevent page_frag_alloc() from corrupting the memory
A number of drivers call page_frag_alloc() with a fragment's size >
PAGE_SIZE.
In low memory conditions, __page_frag_cache_refill() may fail the order
3 cache allocation and fall back to order 0; In this case, the cache
will be smaller than the fragment, causing memory corruptions.
Prevent this from happening by checking if the newly allocated cache is
large enough for the fragment; if not, the allocation will fail and
page_frag_alloc() will return NULL.

Before the commit update_mmu_cache() was called during a call to
filemap_map_pages() as well as finish_fault(). After the commit
finish_fault() lacks it.
Bring back update_mmu_cache() to finish_fault() to fix the bug.
Also call update_mmu_tlb() only when returning VM_FAULT_NOPAGE to more
closely reproduce the code of alloc_set_pte() function that existed before
the commit.
On many platforms update_mmu_cache() is nop:
x86, see arch/x86/include/asm/pgtable
ARMv6+, see arch/arm/include/asm/tlbflush.h
So, it seems, few users ran into this bug.

powerpc/64s/radix: don't need to broadcast IPI for radix pmd collapse flush
The IPI broadcast is used to serialize against fast-GUP, but fast-GUP will
move to use RCU instead of disabling local interrupts in fast-GUP. Using
an IPI is the old-styled way of serializing against fast-GUP although it
still works as expected now.
And fast-GUP now fixed the potential race with THP collapse by checking
whether PMD is changed or not. So IPI broadcast in radix pmd collapse
flush is not necessary anymore. But it is still needed for hash TLB.

mm: gup: fix the fast GUP race against THP collapse
Since general RCU GUP fast was introduced in commit 660df827001f ("mm:
introduce a general RCU get_user_pages_fast()"), a TLB flush is no longer
sufficient to handle concurrent GUP-fast in all cases, it only handles
traditional IPI-based GUP-fast correctly. On architectures that send an
IPI broadcast on TLB flush, it works as expected. But on the
architectures that do not use IPI to broadcast TLB flush, it may have the
below race:
CPU A CPU B
THP collapse fast GUP
gup_pmd_range() <-- see valid pmd
gup_pte_range() <-- work on pte
pmdp_collapse_flush() <-- clear pmd and flush
__collapse_huge_page_isolate()
check page pinned <-- before GUP bump refcount
pin the page
check PTE <-- no change
__collapse_huge_page_copy()
copy data to huge page
ptep_clear()
install huge pmd for the huge page
return the stale page
discard the stale page
The race can be fixed by checking whether PMD is changed or not after
taking the page pin in fast GUP, just like what it does for PTE. If the
PMD is changed it means there may be parallel THP collapse, so GUP should
back off.
Also update the stale comment about serializing against fast GUP in
khugepaged.

drm/i915/gt: Restrict forced preemption to the active context
When we submit a new pair of contexts to ELSP for execution, we start a
timer by which point we expect the HW to have switched execution to the
pending contexts. If the promotion to the new pair of contexts has not
occurred, we declare the executing context to have hung and force the
preemption to take place by resetting the engine and resubmitting the
new contexts.
This can lead to an unfair situation where almost all of the preemption
timeout is consumed by the first context which just switches into the
second context immediately prior to the timer firing and triggering the
preemption reset (assuming that the timer interrupts before we process
the CS events for the context switch). The second context hasn't yet had
a chance to yield to the incoming ELSP (and send the ACk for the
promotion) and so ends up being blamed for the reset.
If we see that a context switch has occurred since setting the
preemption timeout, but have not yet received the ACK for the ELSP
promotion, rearm the preemption timer and check again. This is
especially significant if the first context was not schedulable and so
we used the shortest timer possible, greatly increasing the chance of
accidentally blaming the second innocent context.
