PATCH 1/118 mptcp: sockopt: make tcp_fastopen_connect generic

In reply to Greg Kroah-Hartman

From: Matthieu Baerts <[email protected]>

[ Upstream commit d3d429047cc66ff49780c93e4fccd9527723d385 ]

There are other socket options that need to act only on the first subflow, e.g. all TCP_FASTOPEN* socket options.

This is similar to the getsockopt version.

In the next commit, this new mptcp_setsockopt_first_sf_only() helper is used by other another option.

Stable-dep-of: 21e43569685d ("mptcp: fix locking for setsockopt corner-case")

PATCH 10/118 ASoC: Intel: sof_rt5682: always set dpcm_capture for amplifiers

In reply to Greg Kroah-Hartman

From: Pierre-Louis Bossart <[email protected]>

[ Upstream commit 324f065cdbaba1b879a63bf07e61ca156b789537 ]

The amplifier may provide hardware support for I/V feedback, or alternatively the firmware may generate an echo reference attached to the SSP and dailink used for the amplifier.

To avoid any issues with invalid/NULL substreams in the latter case, always unconditionally set dpcm_capture.

PATCH 15/118 ALSA: hda: Do not unset preset when cleaning up codec

In reply to Greg Kroah-Hartman

From: Cezary Rojewski <[email protected]>

[ Upstream commit 87978e6ad45a16835cc58234451111091be3c59a ]

Several functions that take part in codec's initialization and removal are re-used by ASoC codec drivers implementations. Drivers mimic the behavior of hda_codec_driver_probe/remove() found in sound/pci/hda/hda_bind.c with their component->probe/remove() instead.

One of the reasons for that is the expectation of snd_hda_codec_device_new() to receive a valid pointer to an instance of struct snd_card. This expectation can be met only once sound card components probing commences.

As ASoC sound card may be unbound without codec device being actually removed from the system, unsetting ->preset in snd_hda_codec_cleanup_for_unbind() interferes with module unload -> load scenario causing null-ptr-deref. Preset is assigned only once, during device/driver matching whereas ASoC codec driver's module reloading may occur several times throughout the lifetime of an audio stack.

PATCH 18/118 ASoC: cs42l56: fix DT probe

In reply to Greg Kroah-Hartman

From: Arnd Bergmann <[email protected]>

[ Upstream commit e18c6da62edc780e4f4f3c9ce07bdacd69505182 ]

While looking through legacy platform data users, I noticed that the DT probing never uses data from the DT properties, as the platform_data structure gets overwritten directly after it is initialized.

There have never been any boards defining the platform_data in the mainline kernel either, so this driver so far only worked with patched kernels or with the default values.

For the benefit of possible downstream users, fix the DT probe by no longer overwriting the data.

PATCH 2/118 mptcp: fix locking for setsockopt corner-case

In reply to Greg Kroah-Hartman

From: Paolo Abeni <[email protected]>

[ Upstream commit 21e43569685de4ad773fb060c11a15f3fd5e7ac4 ]

We need to call the __mptcp_nmpc_socket(), and later subflow socket access under the msk socket lock, or e.g. a racing connect() could change the socket status under the hood, with unexpected results.

Fixes 54635bd04701 ("mptcp: add TCP_FASTOPEN_CONNECT socket option")

PATCH 21/118 net/rose: Fix to not accept on connected socket

In reply to Greg Kroah-Hartman

From: Hyunwoo Kim <[email protected]>

[ Upstream commit 14caefcf9837a2be765a566005ad82cd0d2a429f ]

If you call listen() and accept() on an already connect()ed rose socket, accept() can successfully connect. This is because when the peer socket sends data to sendmsg, the skb with its own sk stored in the connected socket's sk->sk_receive_queue is connected, and rose_accept() dequeues the skb waiting in the sk->sk_receive_queue.

This creates a child socket with the sk of the parent rose socket, which can cause confusion.

Fix rose_listen() to return -EINVAL if the socket has already been successfully connected, and add lock_sock to prevent this issue.

PATCH 22/118 selftest: net: Improve IPV6_TCLASS/IPV6_HOPLIMIT tests apparmor compatibility

In reply to Greg Kroah-Hartman

From: Andrei Gherzan <[email protected]>

[ Upstream commit a6efc42a86c0c87cfe2f1c3d1f09a4c9b13ba890 ]

"tcpdump" is used to capture traffic in these tests while using a random, temporary and not suffixed file for it. This can interfere with apparmor configuration where the tool is only allowed to read from files with 'known' extensions.

The MINE type application/vnd.tcpdump.pcap was registered with IANA for pcap files and .pcap is the extension that is both most common but also aligned with standard apparmor configurations. See TCPDUMP(8) for more details.

This improves compatibility with standard apparmor configurations by using ".pcap" as the file extension for the tests' temporary files.

PATCH 23/118 net: stmmac: do not stop RX_CLK in Rx LPI state for qcs404 SoC

In reply to Greg Kroah-Hartman

From: Andrey Konovalov <[email protected]>

[ Upstream commit 54aa39a513dbf2164ca462a19f04519b2407a224 ]

Currently in phy_init_eee() the driver unconditionally configures the PHY to stop RX_CLK after entering Rx LPI state. This causes an LPI interrupt storm on my qcs404-base board.

Change the PHY initialization so that for "qcom,qcs404-ethqos" compatible device RX_CLK continues to run even in Rx LPI state.

PATCH 24/118 powerpc/64: Fix perf profiling asynchronous interrupt handlers

In reply to Greg Kroah-Hartman

From: Nicholas Piggin <[email protected]>

[ Upstream commit c28548012ee2bac55772ef7685138bd1124b80c3 ]

Interrupt entry sets the soft mask to IRQS_ALL_DISABLED to match the hard irq disabled state. So when should_hard_irq_enable() returns true because we want PMI interrupts in irq handlers, MSR[EE] is enabled but PMIs just get soft-masked. Fix this by clearing IRQS_PMI_DISABLED before enabling MSR[EE].

This also tidies some of the warnings, no need to duplicate them in both should_hard_irq_enable() and do_hard_irq_enable().

PATCH 25/118 fscache: Use clear_and_wake_up_bit() in fscache_create_volume_work()

In reply to Greg Kroah-Hartman

From: Hou Tao <[email protected]>

[ Upstream commit 3288666c72568fe1cc7f5c5ae33dfd3ab18004c8 ]

fscache_create_volume_work() uses wake_up_bit() to wake up the processes which are waiting for the completion of volume creation. According to comments in wake_up_bit() and waitqueue_active(), an extra smp_mb() is needed to guarantee the memory order between FSCACHE_VOLUME_CREATING flag and waitqueue_active() before invoking wake_up_bit().

Fixing it by using clear_and_wake_up_bit() to add the missing memory barrier.

PATCH 26/118 drm/nouveau/devinit/tu102-: wait for GFW_BOOT_PROGRESS == COMPLETED

In reply to Greg Kroah-Hartman

From: Ben Skeggs <[email protected]>

[ Upstream commit d22915d22ded21fd5b24b60d174775789f173997 ]

Starting from Turing, the driver is no longer responsible for initiating DEVINIT when required as the GPU started loading a FW image from ROM and executing DEVINIT itself after power-on.

However - we apparently still need to wait for it to complete.

This should correct some issues with runpm on some systems, where we get control of the HW before it's been fully reinitialised after resume from suspend.

PATCH 27/118 net: ethernet: mtk_eth_soc: Avoid truncating allocation

There doesn't appear to be a reason to truncate the allocation used for flow_info, so do a full allocation and remove the unused empty struct. GCC does not like having a reference to an object that has been partially allocated, as bounds checking may become impossible when such an object is passed to other code. Seen with GCC 13:

PATCH 29/118 s390/decompressor: specify __decompress() buf len to avoid overflow

In reply to Greg Kroah-Hartman

From: Vasily Gorbik <[email protected]>

[ Upstream commit 7ab41c2c08a32132ba8c14624910e2fe8ce4ba4b ]

Historically calls to __decompress() didn't specify "out_len" parameter on many architectures including s390, expecting that no writes beyond uncompressed kernel image are performed. This has changed since commit 2aa14b1ab2c4 ("zstd: import usptream v1.5.2") which includes zstd library commit 6a7ede3dfccb ("Reduce size of dctx by reutilizing dst buffer (#2751)"). Now zstd decompression code might store literal buffer in the unwritten portion of the destination buffer. Since "out_len" is not set, it is considered to be unlimited and hence free to use for optimization needs. On s390 this might corrupt initrd or ipl report which are often placed right after the decompressor buffer. Luckily the size of uncompressed kernel image is already known to the decompressor, so to avoid the problem simply specify it in the "out_len" parameter.

PATCH 3/118 mptcp: deduplicate error paths on endpoint creation

In reply to Greg Kroah-Hartman

From: Paolo Abeni <[email protected]>

[ Upstream commit 976d302fb6165ad620778d7ba834cde6e3fe9f9f ]

When endpoint creation fails, we need to free the newly allocated entry and eventually destroy the paired mptcp listener socket.

Consolidate such action in a single point let all the errors path reach it.

PATCH 4/118 mptcp: fix locking for in-kernel listener creation

In reply to Greg Kroah-Hartman

From: Paolo Abeni <[email protected]>

[ Upstream commit ad2171009d968104ccda9dc517f5a3ba891515db ]

For consistency, in mptcp_pm_nl_create_listen_socket(), we need to call the __mptcp_nmpc_socket() under the msk socket lock.

Note that as a side effect, mptcp_subflow_create_socket() needs a 'nested' lockdep annotation, as it will acquire the subflow (kernel) socket lock under the in-kernel listener msk socket lock.

The current lack of locking is almost harmless, because the relevant socket is not exposed to the user space, but in future we will add more complexity to the mentioned helper, let's play safe.

Fixes 1729cf186d8a ("mptcp: create the listening socket for new port")

PATCH 6/118 btrfs: lock the inode in shared mode before starting fiemap

In reply to Greg Kroah-Hartman

From: Filipe Manana <[email protected]>

[ Upstream commit 519b7e13b5ae8dd38da1e52275705343be6bb508 ]

Currently fiemap does not take the inode's lock (VFS lock), it only locks a file range in the inode's io tree. This however can lead to a deadlock if we have a concurrent fsync on the file and fiemap code triggers a fault when accessing the user space buffer with fiemap_fill_next_extent(). The deadlock happens on the inode's i_mmap_lock semaphore, which is taken both by fsync and btrfs_page_mkwrite(). This deadlock was recently reported by syzbot and triggers a trace like the following:

task:syz-executor361 state:D stack:20264 pid:5668 ppid:5119 flags:0x00004004

    </TASK>

What happens is the following:

1) Task A is doing an fsync, enters btrfs_sync_file() and flushes delalloc before locking the inode and the i_mmap_lock semaphore, that is, before calling btrfs_inode_lock();

2) After task A flushes delalloc and before it calls btrfs_inode_lock(), another task dirties a page;

3) Task B starts a fiemap without FIEMAP_FLAG_SYNC, so the page dirtied at step 2 remains dirty and unflushed. Then when it enters extent_fiemap() and it locks a file range that includes the range of the page dirtied in step 2;

4) Task A calls btrfs_inode_lock() and locks the inode (VFS lock) and the inode's i_mmap_lock semaphore in write mode. Then it tries to flush delalloc by calling start_ordered_ops(), which will block, at find_lock_delalloc_range(), when trying to lock the range of the page dirtied at step 2, since this range was locked by the fiemap task (at step 3);

5) Task B generates a page fault when accessing the user space fiemap buffer with a call to fiemap_fill_next_extent().

The fault handler needs to call btrfs_page_mkwrite() for some other page of our inode, and there we deadlock when trying to lock the inode's i_mmap_lock semaphore in read mode, since the fsync task locked it in write mode (step 4) and the fsync task can not progress because it's waiting to lock a file range that is currently locked by us (the fiemap task, step 3).

Fix this by taking the inode's lock (VFS lock) in shared mode when entering fiemap. This effectively serializes fiemap with fsync (except the most expensive part of fsync, the log sync), preventing this deadlock.

PATCH 8/118 ASoC: SOF: sof-audio: start with the right widget type

In reply to Greg Kroah-Hartman

From: Bard Liao <[email protected]>

[ Upstream commit fcc4348adafe53928fda46d104c1798e5a4de4ff ]

If there is a connection between a playback stream and a capture stream, all widgets that are connected to the playback stream and the capture stream will be in the list.
So, we have to start with the exactly right widget type. snd_soc_dapm_aif_out is for capture stream and a playback stream should start with a snd_soc_dapm_aif_in widget.
Contrarily, snd_soc_dapm_dai_in is for playback stream, and a capture stream should start with a snd_soc_dapm_dai_out widget.

PATCH 31/118 nvme: clear the request_queue pointers on failure in nvme_alloc_admin_tag_set

From: Maurizio Lombardi <[email protected]>

[ Upstream commit fd62678ab55cb01e11a404d302cdade222bf4022 ]

If nvme_alloc_admin_tag_set() fails, the admin_q and fabrics_q pointers are left with an invalid, non-NULL value. Other functions may then check the pointers and dereference them, e.g. in

nvme_probe() -> out_disable: -> nvme_dev_remove_admin().

Fix the bug by setting admin_q and fabrics_q to NULL in case of error.

Also use the set variable to free the tag_set as ctrl->admin_tagset isn't initialized yet.

PATCH 40/118 platform/x86: touchscreen_dmi: Add Chuwi Vi8 (CWI501) DMI match

In reply to Greg Kroah-Hartman

From: Hans de Goede <[email protected]>

[ Upstream commit eecf2acd4a580e9364e5087daf0effca60a240b7 ]

Add a DMI match for the CWI501 version of the Chuwi Vi8 tablet, pointing to the same chuwi_vi8_data as the existing CWI506 version DMI match.

PATCH 41/118 ceph: move mount state enum to super.h

In reply to Greg Kroah-Hartman

From: Xiubo Li <[email protected]>

[ Upstream commit b38b17b6a01ca4e738af097a1529910646ef4270 ]

These flags are only used in ceph filesystem in fs/ceph, so just move it to the place it should be.

PATCH 42/118 ceph: blocklist the kclient when receiving corrupted snap trace

In reply to Greg Kroah-Hartman

From: Xiubo Li <[email protected]>

[ Upstream commit a68e564adcaa69b0930809fb64d9d5f7d9c32ba9 ]

When received corrupted snap trace we don't know what exactly has happened in MDS side. And we shouldn't continue IOs and metadatas access to MDS, which may corrupt or get incorrect contents.

This patch will just block all the further IO/MDS requests immediately and then evict the kclient itself.

The reason why we still need to evict the kclient just after blocking all the further IOs is that the MDS could revoke the caps faster.

PATCH 43/118 selftests: mptcp: userspace: fix v4-v6 test in v6.1

In reply to Greg Kroah-Hartman

From: Matthieu Baerts <[email protected]>

The commit 4656d72c1efa ("selftests: mptcp: userspace: validate v4-v6 subflows mix") has been backported to v6.1.8 without any conflicts. But it looks like it was depending on a previous one:

commit 1cc94ac1af4b ("selftests: mptcp: make evts global in userspace_pm")

Without it, the test fails with:

./userspace_pm.sh: line 788: : No such file or directory
# ADD_ADDR4 id:14 10.0.2.1 (ns1) => ns2, reuse port [FAIL]
sed: can't read : No such file or directory

This dependence refactors the way the monitoring files are being
created: only once for all the different sub-tests instead of per sub-test.

It is probably better to avoid backporting the refactoring. That is why the new sub-test has been adapted to work using the previous way that is still in place here in v6.1: the monitoring is started at the beginning of each sub-test and the created file is removed at the end.

Fixes f59549814a64 ("selftests: mptcp: userspace: validate v4-v6 subflows mix")

PATCH 44/118 of: reserved_mem: Have kmemleak ignore dynamically allocated reserved mem

In reply to Greg Kroah-Hartman

From: Isaac J. Manjarres <[email protected]>

commit ce4d9a1ea35ac5429e822c4106cb2859d5c71f3e upstream.

Patch series "Fix kmemleak crashes when scanning CMA regions", v2.

When trying to boot a device with an ARM64 kernel with the following config options enabled:

CONFIG_DEBUG_PAGEALLOC=y
CONFIG_DEBUG_PAGEALLOC_ENABLE_DEFAULT=y
CONFIG_DEBUG_KMEMLEAK=y

a crash is encountered when kmemleak starts to scan the list of gray or allocated objects that it maintains. Upon closer inspection, it was observed that these page-faults always occurred when kmemleak attempted to scan a CMA region.

At the moment, kmemleak is made aware of CMA regions that are specified through the devicetree to be dynamically allocated within a range of addresses. However, kmemleak should not need to scan CMA regions or any reserved memory region, as those regions can be used for DMA transfers between drivers and peripherals, and thus wouldn't contain anything useful for kmemleak.

Additionally, since CMA regions are unmapped from the kernel's address space when they are freed to the buddy allocator at boot when CONFIG_DEBUG_PAGEALLOC is enabled, kmemleak shouldn't attempt to access those memory regions, as that will trigger a crash. Thus, kmemleak should ignore all dynamically allocated reserved memory regions.

This patch (of 1):

Currently, kmemleak ignores dynamically allocated reserved memory regions that don't have a kernel mapping. However, regions that do retain a kernel mapping (e.g. CMA regions) do get scanned by kmemleak.

This is not ideal for two reasons:

1 kmemleak works by scanning memory regions for pointers to allocated
objects to determine if those objects have been leaked or not. However, reserved memory regions can be used between drivers and peripherals for DMA transfers, and thus, would not contain pointers to allocated objects, making it unnecessary for kmemleak to scan these reserved memory regions.

2 When CONFIG_DEBUG_PAGEALLOC is enabled, along with kmemleak, the
CMA reserved memory regions are unmapped from the kernel's address space when they are freed to buddy at boot. These CMA reserved regions are still tracked by kmemleak, however, and when kmemleak attempts to scan them, a crash will happen, as accessing the CMA region will result in a page-fault, since the regions are unmapped.

Thus, use kmemleak_ignore_phys() for all dynamically allocated reserved memory regions, instead of those that do not have a kernel mapping associated with them.

The Oops is due to kasan_byte_accessible() not checking the readiness of KASAN. Add missing call to kasan_arch_is_ready() and bail out when not ready. The same problem is observed with ____kasan_kfree_large() so fix it the same.

Also, as KASAN is not available and no shadow area is allocated for linear memory mapping, there is no point in allocating shadow mem for vmalloc memory as shown below in /sys/kernel/debug/kernel_page_tables

---[ kasan shadow mem start ]---

  0xc00f000000000000-0xc00f00000006ffff  0x00000000040f0000       448K         r  w       pte  valid  present        dirty  accessed

---[ kasan shadow mem end ]---

So, also verify KASAN readiness before allocating and poisoning shadow mem for VMAs.

PATCH 46/118 mm: shrinkers: fix deadlock in shrinker debugfs

In reply to Greg Kroah-Hartman

From: Qi Zheng <[email protected]>

commit badc28d4924bfed73efc93f716a0c3aa3afbdf6f upstream.

The debugfs_remove_recursive() is invoked by unregister_shrinker(), which is holding the write lock of shrinker_rwsem. It will waits for the handler of debugfs file complete. The handler also needs to hold the read lock of shrinker_rwsem to do something. So it may cause the following deadlock:

CPU0 CPU1

debugfs_file_get() shrinker_debugfs_count_show()/shrinker_debugfs_scan_write()

     				unregister_shrinker()
				--> down_write(&shrinker_rwsem);
				    debugfs_remove_recursive()
					// wait for (A)
				    --> wait_for_completion();

    // wait for (B)

--> down_read_killable(&shrinker_rwsem)
debugfs_file_put() -- (A)

				    up_write() -- (B)

The down_read_killable() can be killed, so that the above deadlock can be recovered. But it still requires an extra kill action, otherwise it will block all subsequent shrinker-related operations, so it's better to fix it.

PATCH 48/118 vmxnet3: move rss code block under eop descriptor

In reply to Greg Kroah-Hartman

From: Ronak Doshi <[email protected]>

commit ec76d0c2da5c6dfb6a33f1545cc15997013923da upstream.

Commit b3973bb40041 ("vmxnet3: set correct hash type based on rss information") added hashType information into skb. However, rssType field is populated for eop descriptor. This can lead to incorrectly reporting of hashType for packets which use multiple rx descriptors. Multiple rx descriptors are used for Jumbo frame or LRO packets, which can hit this issue.

This patch moves the RSS codeblock under eop descritor.

PATCH 49/118 fbdev: Fix invalid page access after closing deferred I/O devices

In reply to Greg Kroah-Hartman

From: Takashi Iwai <[email protected]>

commit 3efc61d95259956db25347e2a9562c3e54546e20 upstream.

When a fbdev with deferred I/O is once opened and closed, the dirty pages still remain queued in the pageref list, and eventually later those may be processed in the delayed work. This may lead to a corruption of pages, hitting an Oops.

This patch makes sure to cancel the delayed work and clean up the pageref list at closing the device for addressing the bug. A part of the cleanup code is factored out as a new helper function that is called from the common fb_release().

PATCH 50/118 drm: Disable dynamic debug as broken

In reply to Greg Kroah-Hartman

From: Ville Syrjälä <[email protected]>

commit bb2ff6c27bc9e1da4d3ec5e7b1d6b9df1092cb5a upstream.

CONFIG_DRM_USE_DYNAMIC_DEBUG breaks debug prints for (at least modular) drm drivers. The debug prints can be reinstated by manually frobbing /sys/module/drm/parameters/debug after the fact, but at that point the damage is done and all debugs from driver probe are lost. This makes drivers totally undebuggable.

There's a more complete fix in progress [1], with further details, but we need this fixed in stable kernels. Mark the feature as broken and disable it by default, with hopes distros follow suit and disable it as well.

PATCH 52/118 drm/amd/display: Fail atomic_check early on normalize_zpos error

In reply to Greg Kroah-Hartman

From: Leo Li <[email protected]>

commit 2a00299e7447395d0898e7c6214817c06a61a8e8 upstream.

[Why]

drm_atomic_normalize_zpos() can return an error code when there's modeset lock contention. This was being ignored.

[How]

Bail out of atomic check if normalize_zpos() returns an error.

PATCH 53/118 drm/vmwgfx: Stop accessing buffer objects which failed init

In reply to Greg Kroah-Hartman

From: Zack Rusin <[email protected]>

commit 1a6897921f52ceb2c8665ef826e405bd96385159 upstream.

ttm_bo_init_reserved on failure puts the buffer object back which causes it to be deleted, but kfree was still being called on the same buffer in vmw_bo_create leading to a double free.

After the double free the vmw_gem_object_create_with_handle was setting the gem function objects before checking the return status of vmw_bo_create leading to null pointer access.

Fix the entire path by relaying on ttm_bo_init_reserved to delete the buffer objects on failure and making sure the return status is checked before setting the gem function objects on the buffer object.

Fixes 8afa13a0583f ("drm/vmwgfx: Implement DRIVER_GEM")

PATCH 54/118 drm/vmwgfx: Do not drop the reference to the handle too soon

In reply to Greg Kroah-Hartman

From: Zack Rusin <[email protected]>

commit a950b989ea29ab3b38ea7f6e3d2540700a3c54e8 upstream.

v3: Fix vmw_user_bo_lookup which was also dropping the gem reference before the kernel was done with buffer depending on userspace doing the right thing. Same bug, different spot.

It is possible for userspace to predict the next buffer handle and to destroy the buffer while it's still used by the kernel. Delay dropping the internal reference on the buffers until kernel is done with them.

Instead of immediately dropping the gem reference in vmw_user_bo_lookup and vmw_gem_object_create_with_handle let the callers decide when they're ready give the control back to userspace.

Also fixes the second usage of vmw_gem_object_create_with_handle in vmwgfx_surface.c which wasn't grabbing an explicit reference to the gem object which could have been destroyed by the userspace on the owning surface at any point.

Fixes 8afa13a0583f ("drm/vmwgfx: Implement DRIVER_GEM")

PATCH 55/118 mmc: jz4740: Work around bug on JZ4760(B)

In reply to Greg Kroah-Hartman

From: Paul Cercueil <[email protected]>

commit 3f18c5046e633cc4bbad396b74c05d46d353033d upstream.

On JZ4760 and JZ4760B, SD cards fail to run if the maximum clock rate is set to 50 MHz, even though the controller officially does support it.

Until the actual bug is found and fixed, limit the maximum clock rate to 24 MHz.

PATCH 57/118 mmc: sdio: fix possible resource leaks in some error paths

In reply to Greg Kroah-Hartman

From: Yang Yingliang <[email protected]>

commit 605d9fb9556f8f5fb4566f4df1480f280f308ded upstream.

If sdio_add_func() or sdio_init_func() fails, sdio_remove_func() can not release the resources, because the sdio function is not presented in these two cases, it won't call of_node_put() or put_device().

To fix these leaks, make sdio_func_present() only control whether device_del() needs to be called or not, then always call of_node_put() and put_device().

In error case in sdio_init_func(), the reference of 'card->dev' is not get, to avoid redundant put in sdio_free_func_cis(), move the get_device() to sdio_alloc_func() and put_device() to sdio_release_func(), it can keep the get/put function be balanced.

Without this patch, while doing fault inject test, it can get the following leak reports, after this fix, the leak is gone.

PATCH 58/118 mmc: mmc_spi: fix error handling in mmc_spi_probe()

In reply to Greg Kroah-Hartman

From: Yang Yingliang <[email protected]>

commit cf4c9d2ac1e42c7d18b921bec39486896645b714 upstream.

If mmc_add_host() fails, it doesn't need to call mmc_remove_host(), or it will cause null-ptr-deref, because of deleting a not added device in mmc_remove_host().

To fix this, goto label 'fail_glue_init', if mmc_add_host() fails, and change the label 'fail_add_host' to 'fail_gpiod_request'.

PATCH 59/118 ALSA: hda: Fix codec device field initializan

In reply to Greg Kroah-Hartman

From: Cezary Rojewski <[email protected]>

commit 3af4a4f7a20c94009adba65764fa5a0269d70a82 upstream.

Commit f2bd1c5ae2cb ("ALSA: hda: Fix page fault in snd_hda_codec_shutdown()") relocated initialization of several codec device fields. Due to differences between codec_exec_verb() and snd_hdac_bus_exec_bus() in how they handle VERB execution - the latter does not touch PM - assigning ->exec_verb to codec_exec_verb() causes PM to be engaged before it is configured for the device. Configuration of PM for the ASoC HDAudio sound card is done with snd_hda_set_power_save() during skl_hda_audio_probe() whereas the assignment happens early, in snd_hda_codec_device_init().

Revert to previous behavior to avoid problems caused by too early PM manipulation.

There could be boards with DCN listed in IP discovery, but no display hardware actually wired up. In this case the vbios display table will not be populated. Detect this case and skip loading DM when we detect it.

v2: Mark DCN as harvested as well so other display checks elsewhere in the driver are handled properly.

PATCH 71/118 mm/migrate: fix wrongly apply write bit after mkdirty on sparc64

In reply to Greg Kroah-Hartman

From: Peter Xu <[email protected]>

commit 96a9c287e25d690fd9623b5133703b8e310fbed1 upstream.

Nick Bowler reported another sparc64 breakage after the young/dirty persistent work for page migration (per "Link:" below). That's after a similar report [2].

It turns out page migration was overlooked, and it wasn't failing before because page migration was not enabled in the initial report test environment.

David proposed another way [2] to fix this from sparc64 side, but that patch didn't land somehow. Neither did I check whether there's any other arch that has similar issues.

Let's fix it for now as simple as moving the write bit handling to be after dirty, like what we did before.

Note: this is based on mm-unstable, because the breakage was since 6.1 and we're at a very late stage of 6.2 (-rc8), so I assume for this specific case we should target this at 6.3.

PATCH 73/118 freezer,umh: Fix call_usermode_helper_exec() vs SIGKILL

In reply to Greg Kroah-Hartman

From: Peter Zijlstra <[email protected]>

commit eedeb787ebb53de5c5dcf7b7b39d01bf1b0f037d upstream.

Tetsuo-San noted that commit f5d39b020809 ("freezer,sched: Rewrite core freezer logic") broke call_usermodehelper_exec() for the KILLABLE case.

Specifically it was missed that the second, unconditional, wait_for_completion() was not optional and ensures the on-stack completion is unused before going out-of-scope.

PATCH 75/118 Revert "mm: Always release pages to the buddy allocator in memblock_free_late()."

In reply to Greg Kroah-Hartman

From: Aaron Thompson <[email protected]>

commit 647037adcad00f2bab8828d3d41cd0553d41f3bd upstream.

This reverts commit 115d9d77bb0f9152c60b6e8646369fa7f6167593.

The pages being freed by memblock_free_late() have already been initialized, but if they are in the deferred init range, __free_one_page() might access nearby uninitialized pages when trying to coalesce buddies. This can, for example, trigger this BUG:

PATCH 76/118 net: Fix unwanted sign extension in netdev_stats_to_stats64()

In reply to Greg Kroah-Hartman

From: Felix Riemann <[email protected]>

commit 9b55d3f0a69af649c62cbc2633e6d695bb3cc583 upstream.

When converting net_device_stats to rtnl_link_stats64 sign extension is triggered on ILP32 machines as 6c1c509778 changed the previous "ulong -> u64" conversion to "long -> u64" by accessing the net_device_stats fields through a (signed) atomic_long_t.

This causes for example the received bytes counter to jump to 16EiB after having received 2^31 bytes. Casting the atomic value to "unsigned long" beforehand converting it into u64 avoids this.

PATCH 78/118 drm/vc4: crtc: Increase setup cost in core clock calculation to handle extreme reduced blanking

In reply to Greg Kroah-Hartman

From: Dom Cobley <[email protected]>

commit 247a631f9c0ffb37ed0786a94cb4c5f2b6fc7ab1 upstream.

The formula that determines the core clock requirement based on pixel clock and blanking has been determined experimentally to minimise the clock while supporting all modes we've seen.

A new reduced blanking mode (4kp60 at 533MHz rather than the standard 594MHz) has been seen that doesn't produce a high enough clock and results in "flip_done timed out" error.

Increase the setup cost in the formula to make this work. The result is a reduced blanking mode increases by up to 7MHz while leaving the standard timing
mode untouched

PATCH 79/118 drm/vc4: Fix YUV plane handling when planes are in different buffers

In reply to Greg Kroah-Hartman

From: Dave Stevenson <[email protected]>

commit 6b77b16de75a6efc0870b1fa467209387cbee8f3 upstream.

YUV images can either be presented as one allocation with offsets for the different planes, or multiple allocations with 0 offsets.

The driver only ever calls drm_fb_[dma|cma]_get_gem_obj with plane index 0, therefore any application using the second approach was incorrectly rendered.

Correctly determine the address for each plane, removing the assumption that the base address is the same for each.

PATCH 80/118 drm/i915/gen11: Wa_1408615072/Wa_1407596294 should be on GT list

In reply to Greg Kroah-Hartman

From: Matt Roper <[email protected]>

commit d5a1224aa68c8b124a4c5c390186e571815ed390 upstream.

The UNSLICE_UNIT_LEVEL_CLKGATE register programmed by this workaround has 'BUS' style reset, indicating that it does not lose its value on engine resets. Furthermore, this register is part of the GT forcewake domain rather than the RENDER domain, so it should not be impacted by RCS engine resets. As such, we should implement this on the GT workaround list rather than an engine list.

Bspec: 19219

PATCH 81/118 ice: fix lost multicast packets in promisc mode

In reply to Greg Kroah-Hartman

From: Jesse Brandeburg <[email protected]>

commit 43fbca02c2ddc39ff5879b6f3a4a097b1ba02098 upstream.

There was a problem reported to us where the addition of a VF with an IPv6 address ending with a particular sequence would cause the parent device on the PF to no longer be able to respond to neighbor discovery packets.

In this case, we had an ovs-bridge device living on top of a VLAN, which was on top of a PF, and it would not be able to talk anymore (the neighbor entry would expire and couldn't be restored).

The root cause of the issue is that if the PF is asked to be in IFF_PROMISC mode (promiscuous mode) and it had an ipv6 address that needed the 33:33:ff:00:00:04 multicast address to work, then when the VF was added with the need for the same multicast address, the VF would steal all the traffic destined for that address.

The ice driver didn't auto-subscribe a request of IFF_PROMISC to the "multicast replication from other port's traffic" meaning that it won't get for instance, packets with an exact destination in the VF, as above.

The VF's IPv6 address, which adds a "perfect filter" for 33:33:ff:00:00:04, results in no packets for that multicast address making it to the PF (which is in promisc but NOT "multicast replication").

The fix is to enable "multicast promiscuous" whenever the driver is asked to enable IFF_PROMISC, and make sure to disable it when appropriate.

Fixes e94d44786693 ("ice: Implement filter sync, NDO operations and bump version")

PATCH 82/118 ixgbe: allow to increase MTU to 3K with XDP enabled

In reply to Greg Kroah-Hartman

From: Jason Xing <[email protected]>

commit f9cd6a4418bac6a046ee78382423b1ae7565fb24 upstream.

Recently I encountered one case where I cannot increase the MTU size directly from 1500 to a much bigger value with XDP enabled if the server is equipped with IXGBE card, which happened on thousands of servers in production environment. After applying the current patch, we can set the maximum MTU size to 3K.

This patch follows the behavior of changing MTU as i40e/ice does.

[1] commit 23b44513c3e6 ("ice: allow 3k MTU for XDP")
[2] commit 0c8493d90b6b ("i40e: add XDP support for pass and drop actions")

PATCH 84/118 net: bgmac: fix BCM5358 support by setting correct flags

In reply to Greg Kroah-Hartman

From: Rafał Miłecki <[email protected]>

commit d61615c366a489646a1bfe5b33455f916762d5f4 upstream.

Code blocks handling BCMA_CHIP_ID_BCM5357 and BCMA_CHIP_ID_BCM53572 were incorrectly unified. Chip package values are not unique and cannot be checked independently. They are meaningful only in a context of a given chip.

Packages BCM5358 and BCM47188 share the same value but then belong to different chips. Code unification resulted in treating BCM5358 as BCM47188 and broke its initialization.

PATCH 85/118 net: ethernet: ti: am65-cpsw: Add RX DMA Channel Teardown Quirk

In reply to Greg Kroah-Hartman

From: Siddharth Vadapalli <[email protected]>

commit 0ed577e7e8e508c24e22ba07713ecc4903e147c3 upstream.

In TI's AM62x/AM64x SoCs, successful teardown of RX DMA Channel raises an interrupt. The process of servicing this interrupt involves flushing all pending RX DMA descriptors and clearing the teardown completion marker (TDCM). The am65_cpsw_nuss_rx_packets() function invoked from the RX NAPI callback services the interrupt. Thus, it is necessary to wait for this handler to run, drain all packets and clear TDCM, before calling napi_disable() in am65_cpsw_nuss_common_stop() function post channel teardown. If napi_disable() executes before ensuring that TDCM is cleared, the TDCM remains set when the interfaces are down, resulting in an interrupt storm when the interfaces are brought up again.

Since the interrupt raised to indicate the RX DMA Channel teardown is specific to the AM62x and AM64x SoCs, add a quirk for it.

PATCH 87/118 net/sched: tcindex: update imperfect hash filters respecting rcu

In reply to Greg Kroah-Hartman

From: Pedro Tammela <[email protected]>

commit ee059170b1f7e94e55fa6cadee544e176a6e59c2 upstream.

The imperfect hash area can be updated while packets are traversing, which will cause a use-after-free when 'tcf_exts_exec()' is called with the destroyed tcf_ext.

CPU 0: CPU 1:
tcindex_set_parms tcindex_classify
tcindex_lookup
tcindex_lookup
tcf_exts_change
tcf_exts_exec [UAF]

Stop operating on the shared area directly, by using a local copy, and update the filter with 'rcu_replace_pointer()'. Delete the old filter version only after a rcu grace period elapsed.

PATCH 88/118 ice: xsk: Fix cleaning of XDP_TX frames

In reply to Greg Kroah-Hartman

From: Larysa Zaremba <[email protected]>

commit 1f090494170ea298530cf1285fb8d078e355b4c0 upstream.

Incrementation of xsk_frames inside the for-loop produces infinite loop, if we have both normal AF_XDP-TX and XDP_TXed buffers to complete.

Split xsk_frames into 2 variables (xsk_frames and completed_frames) to eliminate this bug.

PATCH 89/118 dccp/tcp: Avoid negative sk_forward_alloc by ipv6_pinfo.pktoptions.

In reply to Greg Kroah-Hartman

From: Kuniyuki Iwashima <[email protected]>

commit ca43ccf41224b023fc290073d5603a755fd12eed upstream.

Eric Dumazet pointed out [0] that when we call skb_set_owner_r() for ipv6_pinfo.pktoptions, sk_rmem_schedule() has not been called, resulting in a negative sk_forward_alloc.

We add a new helper which clones a skb and sets its owner only when sk_rmem_schedule() succeeds.

Note that we move skb_set_owner_r() forward in (dccp|tcp)_v6_do_rcv() because tcp_send_synack() can make sk_forward_alloc negative before ipv6_opt_accepted() in the crossed SYN-ACK or self-connect() cases.

[0]: https://lore.kernel.org/netdev/CANn89iK9oc20Jdi_41jb9URdF210r7d1Y-+uypbMSbOfY6jqrg@mail.gmail.com/

PATCH 90/118 net/usb: kalmia: Dont pass act_len in usb_bulk_msg error path

In reply to Greg Kroah-Hartman

From: Miko Larsson <[email protected]>

commit c68f345b7c425b38656e1791a0486769a8797016 upstream.

syzbot reported that act_len in kalmia_send_init_packet() is uninitialized when passing it to the first usb_bulk_msg error path. Jiri Pirko noted that it's pointless to pass it in the error path, and that the value that would be printed in the second error path would be the value of act_len from the first call to usb_bulk_msg.[1]

With this in mind, let's just not pass act_len to the usb_bulk_msg error paths.

PATCH 64/118 ata: ahci: Add Tiger Lake UP{3,4} AHCI controller

In reply to Greg Kroah-Hartman

From: Simon Gaiser <[email protected]>

commit 104ff59af73aba524e57ae0fef70121643ff270e upstream.

Mark the Tiger Lake UP{3,4} AHCI controller as "low_power". This enables S0ix to work out of the box. Otherwise this isn't working unless the user manually sets /sys/class/scsi_host/*/link_power_management_policy.

Intel lists a total of 4 SATA controller IDs in [1] for those mobile PCHs. This commit just adds the "AHCI" variant since I only tested those.

PATCH 91/118 net/sched: act_ctinfo: use percpu stats

In reply to Greg Kroah-Hartman

From: Pedro Tammela <[email protected]>

commit 21c167aa0ba943a7cac2f6969814f83bb701666b upstream.

The tc action act_ctinfo was using shared stats, fix it to use percpu stats since bstats_update() must be called with locks or with a percpu pointer argument.

PATCH 93/118 net: stmmac: fix order of dwmac5 FlexPPS parametrization sequence

In reply to Greg Kroah-Hartman

From: Johannes Zink <[email protected]>

commit 4562c65ec852067c6196abdcf2d925f08841dcbc upstream.

So far changing the period by just setting new period values while running did not work.

The order as indicated by the publicly available reference manual of the i.MX8MP [1] indicates a sequence:

* initiate the programming sequence
* set the values for PPS period and start time
* start the pulse train generation.

This is currently not used in dwmac5_flex_pps_config(), which instead does:

* initiate the programming sequence and immediately start the pulse train generation
* set the values for PPS period and start time

This caused the period values written not to take effect until the FlexPPS output was disabled and re-enabled again.

This patch fix the order and allows the period to be set immediately.

PATCH 65/118 ata: libata-core: Disable READ LOG DMA EXT for Samsung MZ7LH

In reply to Greg Kroah-Hartman

From: Patrick McLean <[email protected]>

commit ead089577e0f55b238f980d9f62eaa90b7b64672 upstream.

Samsung MZ7LH drives are spewing messages like this in to dmesg with AMD SATA controllers:

ata1.00: exception Emask 0x0 SAct 0x7e0000 SErr 0x0 action 0x6 frozen ata1.00: failed command: SEND FPDMA QUEUED

Since this was seen previously with SSD 840 EVO drives in
https://bugzilla.kernel.org/show_bug.cgi?id=203475 let's add the same fix for these drives as the EVOs have, since they likely have very similar firmwares.

PATCH 66/118 sched/psi: Fix use-after-free in ep_remove_wait_queue()

In reply to Greg Kroah-Hartman

From: Munehisa Kamata <[email protected]>

commit c2dbe32d5db5c4ead121cf86dabd5ab691fb47fe upstream.

If a non-root cgroup gets removed when there is a thread that registered trigger and is polling on a pressure file within the cgroup, the polling waitqueue gets freed in the following path:

do_rmdir
cgroup_rmdir
kernfs_drain_open_files
cgroup_file_release
cgroup_pressure_release
psi_trigger_destroy

However, the polling thread still has a reference to the pressure file and will access the freed waitqueue when the file is closed or upon exit:

fput
ep_eventpoll_release
ep_free
ep_remove_wait_queue
remove_wait_queue

This results in use-after-free as pasted below.

The fundamental problem here is that cgroup_file_release() (and consequently waitqueue's lifetime) is not tied to the file's real lifetime. Using wake_up_pollfree() here might be less than ideal, but it is in line with the comment at commit 42288cb44c4b ("wait: add wake_up_pollfree()") since the waitqueue's lifetime is not tied to file's one and can be considered as another special case. While this would be fixable by somehow making cgroup_file_release() be tied to the fput(), it would require sizable refactoring at cgroups or higher layer which might be more justifiable if we identify more cases like this.

PATCH 67/118 hugetlb: check for undefined shift on 32 bit architectures

In reply to Greg Kroah-Hartman

From: Mike Kravetz <[email protected]>

commit ec4288fe63966b26d53907212ecd05dfa81dd2cc upstream.

Users can specify the hugetlb page size in the mmap, shmget and memfd_create system calls. This is done by using 6 bits within the flags argument to encode the base-2 logarithm of the desired page size. The routine hstate_sizelog() uses the log2 value to find the corresponding hugetlb hstate structure. Converting the log2 value (page_size_log) to potential hugetlb page size is the simple statement:

1UL << page_size_log

Because only 6 bits are used for page_size_log, the left shift can not be greater than 63. This is fine on 64 bit architectures where a long is 64 bits. However, if a value greater than 31 is passed on a 32 bit architecture (where long is 32 bits) the shift will result in undefined behavior. This was generally not an issue as the result of the undefined shift had to exactly match hugetlb page size to proceed.

Recent improvements in runtime checking have resulted in this undefined behavior throwing errors such as reported below.

Fix by comparing page_size_log to BITS_PER_LONG before doing shift.

PATCH 68/118 nilfs2: fix underflow in second superblock position calculations

In reply to Greg Kroah-Hartman

From: Ryusuke Konishi <[email protected]>

commit 99b9402a36f0799f25feee4465bfa4b8dfa74b4d upstream.

Macro NILFS_SB2_OFFSET_BYTES, which computes the position of the second superblock, underflows when the argument device size is less than 4096 bytes. Therefore, when using this macro, it is necessary to check in advance that the device size is not less than a lower limit, or at least that underflow does not occur.

The current nilfs2 implementation lacks this check, causing out-of-bound block access when mounting devices smaller than 4096 bytes:

I/O error, dev loop0, sector 36028797018963960 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 2
NILFS (loop0): unable to read secondary superblock (blocksize = 1024)

In addition, when trying to resize the filesystem to a size below 4096 bytes, this underflow occurs in nilfs_resize_fs(), passing a huge number of segments to nilfs_sufile_resize(), corrupting parameters such as the number of segments in superblocks. This causes excessive loop iterations in nilfs_sufile_resize() during a subsequent resize ioctl, causing semaphore ns_segctor_sem to block for a long time and hang the writer thread:

PATCH 69/118 mm/MADV_COLLAPSE: set EAGAIN on unexpected page refcount

In reply to Greg Kroah-Hartman

From: Zach O'Keefe <[email protected]>

commit ae63c898f4004bbc7d212f4adcb3bb14852c30d6 upstream.

During collapse, in a few places we check to see if a given small page has any unaccounted references. If the refcount on the page doesn't match our expectations, it must be there is an unknown user concurrently interested in the page, and so it's not safe to move the contents elsewhere. However, the unaccounted pins are likely an ephemeral state.

In this situation, MADV_COLLAPSE returns -EINVAL when it should return -EAGAIN. This could cause userspace to conclude that the syscall failed, when it in fact could succeed by retrying.

PATCH 70/118 mm/filemap: fix page end in filemap_get_read_batch

From: Qian Yingjin <[email protected]>

commit 5956592ce337330cdff0399a6f8b6a5aea397a8e upstream.

I was running traces of the read code against an RAID storage system to understand why read requests were being misaligned against the underlying RAID strips. I found that the page end offset calculation in filemap_get_read_batch() was off by one.

When a read is submitted with end offset 1048575, then it calculates the end page for read of 256 when it should be 255. "last_index" is the index of the page beyond the end of the read and it should be skipped when get a batch of pages for read in @filemap_get_read_batch().

The below simple patch fixes the problem. This code was introduced in kernel 5.12.

PATCH 61/118 ALSA: hda/realtek - fixed wrong gpio assigned

In reply to Greg Kroah-Hartman

From: Kailang Yang <[email protected]>

commit 2bdccfd290d421b50df4ec6a68d832dad1310748 upstream.

GPIO2 PIN use for output. Mask Dir and Data need to assign for 0x4. Not 0x3. This fixed was for Lenovo Desktop(0x17aa1056). GPIO2 use for AMP enable.

PATCH 104/118 ipv6: Fix tcp socket connection with DSCP.

In reply to Greg Kroah-Hartman

From: Guillaume Nault <[email protected]>

commit 8230680f36fd1525303d1117768c8852314c488c upstream.

Take into account the IPV6_TCLASS socket option (DSCP) in tcp_v6_connect(). Otherwise fib6_rule_match() can't properly match the DSCP value, resulting in invalid route lookup.

For example:

ip route add unreachable table main 2001:db8::10/124

ip route add table 100 2001:db8::10/124 dev eth0 ip -6 rule add dsfield 0x04 table 100

echo test | socat - TCP6:[2001:db8::11]:54321,ipv6-tclass=0x04

Without this patch, socat fails at connect() time ("No route to host") because the fib-rule doesn't jump to table 100 and the lookup ends up being done in the main table.

Fixes 2cc67cc731d9 ("[IPV6] ROUTE: Routing by Traffic Class.")

PATCH 109/118 nvme-tcp: stop auth work after tearing down queues in error recovery

From: Sagi Grimberg <[email protected]>

[ Upstream commit 1f1a4f89562d3b33b6ca4fc8a4f3bd4cd35ab4ea ]

when starting error recovery there might be a authentication work running, and it involves I/O commands. Given the controller is tearing down there is no chance for the I/O to complete other than timing out which may unnecessarily take a full io timeout.

So first tear down the queues, fail/cancel all inflight I/O (including potentially authentication) and only then stop authentication. This ensures that failover is not stalled due to blocked authentication I/O.

PATCH 112/118 KVM: x86/pmu: Disable vPMU support on hybrid CPUs (host PMUs)

In reply to Greg Kroah-Hartman

From: Sean Christopherson <[email protected]>

commit 4d7404e5ee0066e9a9e8268675de8a273b568b08 upstream.

Disable KVM support for virtualizing PMUs on hosts with hybrid PMUs until KVM gains a sane way to enumeration the hybrid vPMU to userspace and/or gains a mechanism to let userspace opt-in to the dangers of exposing a hybrid vPMU to KVM guests. Virtualizing a hybrid PMU, or at least part of a hybrid PMU, is possible, but it requires careful, deliberate configuration from userspace.

E.g. to expose full functionality, vCPUs need to be pinned to pCPUs to prevent migrating a vCPU between a big core and a little core, userspace must enumerate a reasonable topology to the guest, and guest CPUID must be curated per vCPU to enumerate accurate vPMU capabilities.

The last point is especially problematic, as KVM doesn't control which pCPU it runs on when enumerating KVM's vPMU capabilities to userspace, i.e. userspace can't rely on KVM_GET_SUPPORTED_CPUID in it's current form.

Alternatively, userspace could enable vPMU support by enumerating the set of features that are common and coherent across all cores, e.g. by filtering PMU events and restricting guest capabilities. But again, that requires userspace to take action far beyond reflecting KVM's supported feature set into the guest.

For now, simply disable vPMU support on hybrid CPUs to avoid inducing seemingly random #GPs in guests, and punt support for hybrid CPUs to a future enabling effort.

commit 2c10b61421a28e95a46ab489fd56c0f442ff6952 upstream.

When calling the KVM_GET_DEBUGREGS ioctl, on some configurations, there might be some unitialized portions of the kvm_debugregs structure that could be copied to userspace. Prevent this as is done in the other kvm ioctls, by setting the whole structure to 0 before copying anything into it.

Bonus is that this reduces the lines of code as the explicit flag setting and reserved space zeroing out can be removed.

PATCH 96/118 net: stmmac: Restrict warning on disabling DMA store and fwd mode

In reply to Greg Kroah-Hartman

From: Cristian Ciocaltea <[email protected]>

commit 05d7623a892a9da62da0e714428e38f09e4a64d8 upstream.

When setting 'snps,force_thresh_dma_mode' DT property, the following warning is always emitted, regardless the status of force_sf_dma_mode:

dwmac-starfive 10020000.ethernet: force_sf_dma_mode is ignored if force_thresh_dma_mode is set.

Do not print the rather misleading message when DMA store and forward mode is already disabled.

Fixes e2a240c7d3bc ("driver:net:stmmac: Disable DMA store and forward mode if platform data force_thresh_dma_mode is set.")

PATCH 114/118 perf/x86: Refuse to export capabilities for hybrid PMUs

In reply to Greg Kroah-Hartman

From: Sean Christopherson <[email protected]>

commit 4b4191b8ae1278bde3642acaaef8f92810ed111a upstream.

Now that KVM disables vPMU support on hybrid CPUs, WARN and return zeros if perf_get_x86_pmu_capability() is invoked on a hybrid CPU. The helper doesn't provide an accurate accounting of the PMU capabilities for hybrid CPUs and needs to be enhanced if KVM, or anything else outside of perf, wants to act on the PMU capabilities.

PATCH 115/118 alarmtimer: Prevent starvation by small intervals and SIG_IGN

In reply to Greg Kroah-Hartman

From: Thomas Gleixner <[email protected]>

commit d125d1349abeb46945dc5e98f7824bf688266f13 upstream.

syzbot reported a RCU stall which is caused by setting up an alarmtimer with a very small interval and ignoring the signal. The reproducer arms the alarm timer with a relative expiry of 8ns and an interval of 9ns. Not a problem per se, but that's an issue when the signal is ignored because then the timer is immediately rearmed because there is no way to delay that rearming to the signal delivery path. See posix_timer_fn() and commit 58229a189942 ("posix-timers: Prevent softirq starvation by small intervals and SIG_IGN") for details.

The reproducer does not set SIG_IGN explicitely, but it sets up the timers signal with SIGCONT. That has the same effect as explicitely setting SIG_IGN for a signal as SIGCONT is ignored if there is no handler set and the task is not ptraced.

The log clearly shows that:

[pid 5102] --- SIGCONT {si_signo=SIGCONT, si_code=SI_TIMER, si_timerid=0, si_overrun=316014, si_int=0, si_ptr=NULL} ---

It works because the tasks are traced and therefore the signal is queued so the tracer can see it, which delays the restart of the timer to the signal delivery path. But then the tracer is killed:

[pid 5087] kill(-5102, SIGKILL <unfinished ...>
...
./strace-static-x86_64: Process 5107 detached

and after it's gone the stall can be observed:

syzkaller login: [ 79.439102][ C0] hrtimer: interrupt took 68471 ns

   [  184.460538][    C1] rcu: INFO: rcu_preempt detected stalls on CPUs/tasks:

   [  184.670045][    C0]  alarmtimer_fired+0x327/0x670

posix_timer_fn() prevents that by checking whether the interval for timers which have the signal ignored is smaller than a jiffie and artifically delay it by shifting the next expiry out by a jiffie. That's accurate vs. the overrun accounting, but slightly inaccurate vs. timer_gettimer(2).

The comment in that function says what needs to be done and there was a fix available for the regular userspace induced SIG_IGN mechanism, but that did not work due to the implicit ignore for SIGCONT and similar signals. This needs to be worked on, but for now the only available workaround is to do exactly what posix_timer_fn() does:

Increase the interval of self-rearming timers, which have their signal ignored, to at least a jiffie.

Interestingly this has been fixed before via commit ff86bf0c65f1 ("alarmtimer: Rate limit periodic intervals") already, but that fix got lost in a later rework.

PATCH 116/118 nvme-pci: refresh visible attrs for cmb attributes

commit e917a849c3fc317c4a5f82bb18726000173d39e6 upstream.

The sysfs group containing the cmb attributes is registered before the driver knows if they need to be visible or not. Update the group when cmb attributes are known to exist so the visibility setting is correct.

PATCH 117/118 ASoC: SOF: Intel: hda-dai: fix possible stream_tag leak

In reply to Greg Kroah-Hartman

From: Pierre-Louis Bossart <[email protected]>

commit 1f810d2b6b2fbdc5279644d8b2c140b1f7c9d43d upstream.

The HDaudio stream allocation is done first, and in a second step the LOSIDV parameter is programmed for the multi-link used by a codec.

This leads to a possible stream_tag leak, e.g. if a DisplayAudio link is not used. This would happen when a non-Intel graphics card is used and userspace unconditionally uses the Intel Display Audio PCMs without checking if they are connected to a receiver with jack controls.

We should first check that there is a valid multi-link entry to configure before allocating a stream_tag. This change aligns the dma_assign and dma_cleanup phases.

PATCH 97/118 net: use a bounce buffer for copying skb->mark

In reply to Greg Kroah-Hartman

From: Eric Dumazet <[email protected]>

commit 2558b8039d059342197610498c8749ad294adee5 upstream.

syzbot found arm64 builds would crash in sock_recv_mark() when CONFIG_HARDENED_USERCOPY=y

x86 and powerpc are not detecting the issue because they define user_access_begin.
This will be handled in a different patch, because a check_object_size() is missing.

Only data from skb->cb[] can be copied directly to/from user space, as explained in commit 79a8a642bf05 ("net: Whitelist
the skbuff_head_cache "cb" field")

syzbot report was:
usercopy: Kernel memory exposure attempt detected from SLUB object 'skbuff_head_cache' (offset 168, size 4)!

PATCH 98/118 tipc: fix kernel warning when sending SYN message

commit 11a4d6f67cf55883dc78e31c247d1903ed7feccc upstream.

When sending a SYN message, this kernel stack trace is observed:

It is because commit a41dad905e5a ("iov_iter: saner checks for attempt to copy to/from iterator") has introduced sanity check for copying from/to iov iterator. Lacking of copy direction from the iterator viewpoint would lead to kernel stack trace like above.

This commit fixes this issue by initializing the iov iterator with the correct copy direction when sending SYN or ACK without data.

PATCH 99/118 net: mpls: fix stale pointer if allocation fails during device rename

In reply to Greg Kroah-Hartman

From: Jakub Kicinski <[email protected]>

commit fda6c89fe3d9aca073495a664e1d5aea28cd4377 upstream.

lianhui reports that when MPLS fails to register the sysctl table under new location (during device rename) the old pointers won't get overwritten and may be freed again (double free).

Handle this gracefully. The best option would be unregistering the MPLS from the device completely on failure, but unfortunately mpls_ifdown() can fail. So failing fully is also unreliable.

Another option is to register the new table first then only remove old one if the new one succeeds. That requires more code, changes order of notifications and two tables may be visible at the same time.

sysctl point is not used in the rest of the code - set to NULL on failures and skip unregister if already NULL.

Fixes 0fae3bf018d9 ("mpls: handle device renames for per-device sysctls")

PATCH 100/118 igb: conditionalize I2C bit banging on external thermal sensor support

In reply to Greg Kroah-Hartman

From: Corinna Vinschen <[email protected]>

commit 5d54cb1767e06025819daa6769e0f18dcbc60936 upstream.

Commit a97f8783a937 ("igb: unbreak I2C bit-banging on i350") introduced code to change I2C settings to bit banging unconditionally.

However, this patch introduced a regression: On an Intel S2600CWR Server Board with three NICs:

- 1x dual-port copper
Intel I350 Gigabit Network Connection [8086:1521] (rev 01) fw 1.63, 0x80000dda

- 2x quad-port SFP+ with copper SFP Avago ABCU-5700RZ Intel I350 Gigabit Fiber Network Connection [8086:1522] (rev 01) fw 1.52.0

the SFP NICs no longer get link at all. Reverting commit a97f8783a937 or switching to the Intel out-of-tree driver both fix the problem.

Per the igb out-of-tree driver, I2C bit banging on i350 depends on support for an external thermal sensor (ETS). However, commit a97f8783a937 added bit banging unconditionally. Additionally, the out-of-tree driver always calls init_thermal_sensor_thresh on probe, while our driver only calls init_thermal_sensor_thresh only in igb_reset(), and only if an ETS is present, ignoring the internal thermal sensor. The affected SFPs don't provide an ETS. Per Intel, the behaviour is a result of i350 firmware requirements.

This patch fixes the problem by aligning the behaviour to the out-of-tree driver:

- split igb_init_i2c() into two functions:
- igb_init_i2c() only performs the basic I2C initialization.
- igb_set_i2c_bb() makes sure that E1000_CTRL_I2C_ENA is set and enables bit-banging.

- igb_probe() only calls igb_set_i2c_bb() if an ETS is present.

- igb_probe() calls init_thermal_sensor_thresh() unconditionally.

- igb_reset() aligns its behaviour to igb_probe(), i. e., call igb_set_i2c_bb() if an ETS is present and call init_thermal_sensor_thresh() unconditionally.

PATCH 101/118 igb: Fix PPS input and output using 3rd and 4th SDP

In reply to Greg Kroah-Hartman

PATCH 103/118 ipv6: Fix datagram socket connection with DSCP.

In reply to Greg Kroah-Hartman

From: Guillaume Nault <[email protected]>

commit e010ae08c71fda8be3d6bda256837795a0b3ea41 upstream.

Take into account the IPV6_TCLASS socket option (DSCP) in ip6_datagram_flow_key_init(). Otherwise fib6_rule_match() can't properly match the DSCP value, resulting in invalid route lookup.

For example:

ip route add unreachable table main 2001:db8::10/124

ip route add table 100 2001:db8::10/124 dev eth0 ip -6 rule add dsfield 0x04 table 100

echo test | socat - UDP6:[2001:db8::11]:54321,ipv6-tclass=0x04

Without this patch, socat fails at connect() time ("No route to host") because the fib-rule doesn't jump to table 100 and the lookup ends up being done in the main table.

Fixes 2cc67cc731d9 ("[IPV6] ROUTE: Routing by Traffic Class.")

PATCH 94/118 bnxt_en: Fix mqprio and XDP ring checking logic

In reply to Greg Kroah-Hartman

From: Michael Chan <[email protected]>

commit 2038cc592811209de20c4e094ca08bfb1e6fbc6c upstream.

In bnxt_reserve_rings(), there is logic to check that the number of TX rings reserved is enough to cover all the mqprio TCs, but it fails to account for the TX XDP rings. So the check will always fail if there are mqprio TCs and TX XDP rings. As a result, the driver always fails to initialize after the XDP program is attached and the device will be brought down. A subsequent ifconfig up will also fail because the number of TX rings is set to an inconsistent number. Fix the check to properly account for TX XDP rings. If the check fails, set the number of TX rings back to a consistent number after calling netdev_reset_tc().

Fixes 674f50a5b026 ("bnxt_en: Implement new method to reserve rings.")
