2024-11-13drm/xe: Ensure all locks released in exec IOCTLMatthew Brost
In couple of places the wrong error handling goto was used to release locks. Fix these to ensure all locks dropped on exec IOCTL errors.

2024-11-13s390/cio: Externalize full CMG characteristicsPeter Oberparleiter
The current "measurement_chars" CHPID sysfs attribute exposes only a limited, validity-filtered portion of data from the associated Channel- Measurements Characteristics Block (CMCB). New machine models add data that is relevant for userspace tooling to the "header"-portion of the CMCB. This data that is not currently accessible to userspace. To prevent having to add new sysfs attributes whenever a new bit of data is added to the CMCB "header", add a new sysfs attribute named "measurement_chars_full" that exposes the full, unfiltered CMCB.

This commit fixes the bug in the handling of partial mapping of the buffer objects to the GPU, which caused kernel warnings.

This leads to some incorrect and duplicate mappings. For the case when mr->start < map->start the code is already correct: the range in [mr->start, map->start) was handled by a different iteration.

2024-11-12mmc: sunxi-mmc: Fix A100 compatible descriptionAndre Przywara
It turns out that the Allwinner A100/A133 SoC only supports 8K DMA blocks (13 bits wide), for both the SD/SDIO and eMMC instances. And while this alone would make a trivial fix, the H616 falls back to the A100 compatible string, so we have to now match the H616 compatible string explicitly against the description advertising 64K DMA blocks. As the A100 is now compatible with the D1 description, let the A100 compatible string point to that block instead, and introduce an explicit match against the H616 string, pointing to the old description. Also remove the redundant setting of clk_delays to NULL on the way.

2024-11-11net/mlx5e: Disable loopback self-test on multi-PF netdevCarolina Jubran
In Multi-PF (Socket Direct) configurations, when a loopback packet is sent through one of the secondary devices, it will always be received on the primary device. This causes the loopback layer to fail in identifying the loopback packet as the devices are different. To avoid false test failures, disable the loopback self-test in Multi-PF configurations.

2024-11-11net/mlx5e: kTLS, Fix incorrect page refcountingDragos Tatulea
The kTLS tx handling code is using a mix of get_page() and page_ref_inc() APIs to increment the page reference. But on the release path (mlx5e_ktls_tx_handle_resync_dump_comp()), only put_page() is used. This is an issue when using pages from large folios: the get_page() references are stored on the folio page while the page_ref_inc() references are stored directly in the given page. On release the folio page will be dereferenced too many times. This was found while doing kTLS testing with sendfile() + ZC when the served file was read from NFS on a kernel with NFS large folios support (commit 49b29a573da8 ("nfs: add support for large folios")).

2024-11-11net/mlx5: fs, lock FTE when checking if activeMark Bloch
The referenced commits introduced a two-step process for deleting FTEs: - Lock the FTE, delete it from hardware, set the hardware deletion function to NULL and unlock the FTE. - Lock the parent flow group, delete the software copy of the FTE, and remove it from the xarray. However, this approach encounters a race condition if a rule with the same match value is added simultaneously. In this scenario, fs_core may set the hardware deletion function to NULL prematurely, causing a panic during subsequent rule deletions. To prevent this, ensure the active flag of the FTE is checked under a lock, which will prevent the fs_core layer from attaching a new steering rule to an FTE that is in the process of deletion.

2024-11-11net/mlx5: Fix msix vectors to respect platform limitParav Pandit
The number of PCI vectors allocated by the platform (which may be fewer than requested) is currently not honored when creating the SF pool; only the PCI MSI-X capability is considered. As a result, when a platform allocates fewer vectors (in non-dynamic mode) than requested, the PF and SF pools end up with an invalid vector range. This causes incorrect SF vector accounting, which leads to the following call trace when an invalid IRQ vector is allocated. This issue is resolved by ensuring that the platform's vector limit is respected for both the SF and PF pools.

2024-11-11net/mlx5: E-switch, unload IB representors when unloading ETH representorsChiara Meiohas
IB representors depend on ETH representors, so the IB representors should not exist without the ETH ones. When unloading the ETH representors, the corresponding IB representors should be also unloaded. The commit 8d159eb2117b ("RDMA/mlx5: Use IB set_netdev and get_netdev functions") introduced the use of the ib_device_set_netdev API in IB repsresentors. ib_device_set_netdev() increments the refcount of the representor's netdev when loading an IB representor and decrements it when unloading. Without the unloading of the IB representor, the refcount of the representor's netdev remains greater than 0, preventing it from being unregistered. The patch uncovered an underlying bug where the eth representor is unloaded, without unloading the IB representor. This issue happened when using multiport E-switch and rebooting, causing the shutdown to hang when unloading the ETH representor because the refcount of the representor's netdevice was greater than 0. Call trace: unregister_netdevice: waiting for eth3 to become free.

[Why] In the case where a dml allocation fails for any reason, the current state's dml contexts would no longer be valid. Then subsequent calls dc_state_copy_internal would shallow copy invalid memory and if the new state was released, a double free would occur.

2024-11-11drm/amd/display: Fix Panel Replay not update screen correctlyTom Chung
[Why] In certain use case such as KDE login screen, there will be no atomic commit while do the frame update. If the Panel Replay enabled, it will cause the screen not updated and looks like system hang. [How] Delay few atomic commits before enabled the Panel Replay just like PSR.

2024-11-11nvme: use command set independent id ns if availableMatias Bjørling
The NVMe 2.0 specification adds an independent identify namespace data structure that contains generic attributes that apply to all namespace types. Some attributes carry over from the NVM command set identify namespace data structure, and others are new. Currently, the data structure only considered when CRIMS is enabled or when the namespace type is key-value. However, the independent namespace data structure is mandatory for devices that implement features from the 2.0+ specification. Therefore, we can check this data structure first. If unavailable, retrieve the generic attributes from the NVM command set identify namespace data structure. Signed-off-by: Matias Bjørling <matias.bjorling@wdc.com> Reviewed-by: Martin K.
