2025-06-24ublk: fix narrowing warnings in UAPI headerCaleb Sander Mateos
When a C++ file compiled with -Wc++11-narrowing includes the UAPI header linux/ublk_cmd.h, ublk_sqe_addr_to_auto_buf_reg()'s assignments of u64 values to u8, u16, and u32 fields result in compiler warnings. Add explicit casts to the intended types to avoid these warnings. Drop the unnecessary bitmasks.

2025-06-24ublk: build batch from IOs in same io_ring_ctx and io taskMing Lei
ublk_queue_cmd_list() dispatches the whole batch list by scheduling task work via the tail request's io_uring_cmd, this way is fine even though more than one io_ring_ctx are involved for this batch since it is just one running context. However, the task work handler ublk_cmd_list_tw_cb() takes `issue_flags` of tail uring_cmd's io_ring_ctx for completing all commands. This way is wrong if any uring_cmd is issued from different io_ring_ctx. Fixes it by always building batch IOs from same io_ring_ctx and io task because ublk_dispatch_req() does validate task context, and IO needs to be aborted in case of running from fallback task work context. For typical per-queue or per-io daemon implementation, this way shouldn't make difference from performance viewpoint, because single io_ring_ctx is taken in each daemon for normal use case.

2025-06-24dt-bindings: net: cdns,macb: add sama7d65 ethernet interfaceRyan Wanner
This patch set adds all the supported FLEXCOMs for the SAMA7D65 SoC. This also adds the GMAC interfaces and enables GMAC0 interface for the SAMA7D65 SoC. With the FLEXCOMs added to the SoC the MCP16502 and the MAC address EEPROM are both added to flexcom10. The dt-binding for USART is here [1]. And the dt-binding for DMA has been applied here [2]. The original thread for this is here [3].

This turned out to be a result of missed XDP flush on redirect lists. By digging in the actual source code, we found that commit 7f0a168b0441 ("bnxt_en: Add completion ring pointer in TX and RX ring structures") incorrectly overwrites the event mask for XDP_REDIRECT in bnxt_rx_xdp. We can stably reproduce this crash by returning XDP_TX and XDP_REDIRECT randomly for incoming packets in a naive XDP program. Properly propagate the XDP_REDIRECT events back fixes the crash.

2025-06-24net: xsk: dpaa2: avoid repeatedly updating the global consumerJason Xing
This patch avoids another update of the consumer at the end of dpaa2_xsk_tx(). In the zero copy xmit path, two versions (batched and non-batched) regarding how the consumer of tx ring changes are implemented in xsk_tx_peek_release_desc_batch() that eventually updates the local consumer to the global consumer in either of the following call trace: 1) batched mode: xsk_tx_peek_release_desc_batch() __xskq_cons_release() 2) non-batched mode: xsk_tx_peek_release_desc_batch() xsk_tx_peek_release_fallback() xsk_tx_release() As we can see, dpaa2_xsk_tx() doesn't need to call extra release function to handle the sync of consumer itself.

2025-06-24x86/traps: Initialize DR6 by writing its architectural reset valueXin Li (Intel)
Initialize DR6 by writing its architectural reset value to avoid incorrectly zeroing DR6 to clear DR6.BLD at boot time, which leads to a false bus lock detected warning. The Intel SDM says: 1) Certain debug exceptions may clear bits 0-3 of DR6. 2) BLD induced #DB clears DR6.BLD and any other debug exception doesn't modify DR6.BLD. 3) RTM induced #DB clears DR6.RTM and any other debug exception sets DR6.RTM. To avoid confusion in identifying debug exceptions, debug handlers should set DR6.BLD and DR6.RTM, and clear other DR6 bits before returning. The DR6 architectural reset value 0xFFFF0FF0, already defined as macro DR6_RESERVED, satisfies these requirements, so just use it to reinitialize DR6 whenever needed. Since clear_all_debug_regs() no longer zeros all debug registers, rename it to initialize_debug_regs() to better reflect its current behavior. Since debug_read_clear_dr6() no longer clears DR6, rename it to debug_read_reset_dr6() to better reflect its current behavior.

Commit 869c788909b9 ("selftests: harness: Stop using setjmp()/longjmp()") changed the harness structure. For some unknown reason, two build warnings occur to the iommufd selftest: iommufd.c: In function ‘wrapper_iommufd_mock_domain_all_aligns’: iommufd.c:1807:17: warning: ‘mfd’ may be used uninitialized in this function 1807 | close(mfd); | ^~~~~~~~~~ iommufd.c:1767:13: note: ‘mfd’ was declared here 1767 | int mfd; | ^~~ iommufd.c: In function ‘wrapper_iommufd_mock_domain_all_aligns_copy’: iommufd.c:1870:17: warning: ‘mfd’ may be used uninitialized in this function 1870 | close(mfd); | ^~~~~~~~~~ iommufd.c:1819:13: note: ‘mfd’ was declared here 1819 | int mfd; | ^~~ All the mfd have been used in the variant->file path only, so it's likely a false alarm. FWIW, the commit mentioned above does not cause this, yet it might affect gcc in a certain way that resulted in the warnings. It is also found that ading a dummy setjmp (which doesn't make sense) could mute the warnings: https://lore.kernel.org/all/aEi8DV+ReF3v3Rlf@nvidia.com/ The job of this selftest is to catch kernel bug, while such warnings will unlikely disrupt its role. Mute the warning by force initializing the mfd and add an ASSERT_GT().

2025-06-24iommufd/selftest: Fix iommufd_dirty_tracking with large hugepage sizesNicolin Chen
The hugepage test cases of iommufd_dirty_tracking have the 64MB and 128MB coverages. Both of them are smaller than the default hugepage size 512MB, when CONFIG_PAGE_SIZE_64KB=y. However, these test cases have a variant of using huge pages, which would mmap(MAP_HUGETLB) using these smaller sizes than the system hugepag size. This results in the kernel aligning up the smaller size to 512MB. If a memory was located between the upper 64/128MB size boundary and the hugepage 512MB boundary, it would get wiped out: https://lore.kernel.org/all/aEoUhPYIAizTLADq@nvidia.com/ Given that this aligning up behavior is well documented, we have no choice but to allocate a hugepage aligned size to avoid this unintended wipe out. Instead of relying on the kernel's internal force alignment, pass the same size to posix_memalign() and map(). Also, fix the FIXTURE_TEARDOWN() misusing munmap() to free the memory from posix_memalign(), as munmap() doesn't destroy the allocator meta data. So, call free() instead.

2025-06-24drm/amdgpu/gfx9: Add Cleaner Shader Support for GFX9.x GPUsSrinivasan Shanmugam
Enable the cleaner shader for other GFX9.x series of GPUs to provide data isolation between GPU workloads. The cleaner shader is responsible for clearing the Local Data Store (LDS), Vector General Purpose Registers (VGPRs), and Scalar General Purpose Registers (SGPRs), which helps prevent data leakage and ensures accurate computation results. This update extends cleaner shader support to GFX9.x GPUs, previously available for GFX9.4.2. It enhances security by clearing GPU memory between processes and maintains a consistent GPU state across KGD and KFD workloads.

2025-06-24dt-bindings: serial: 8250: Make clocks and clock-frequency exclusiveYao Zi
The 8250 binding before converting to json-schema states, - clock-frequency : the input clock frequency for the UART or - clocks phandle to refer to the clk used as per Documentation/devicetree for clock-related properties, where "or" indicates these properties shouldn't exist at the same time. Additionally, the behavior of Linux's driver is strange when both clocks and clock-frequency are specified: it ignores clocks and obtains the frequency from clock-frequency, left the specified clocks unclaimed. It may even be disabled, which is undesired most of the time. But "anyOf" doesn't prevent these two properties from coexisting, as it considers the object valid as long as there's at LEAST one match. Let's switch to "oneOf" and disallows the other property if one exists, precisely matching the original binding and avoiding future confusion on the driver's behavior.

2025-06-24serial: imx: Restore original RXTL for console to fix data lossFabio Estevam
Commit 7a637784d517 ("serial: imx: reduce RX interrupt frequency") introduced a regression on the i.MX6UL EVK board. The issue can be reproduced with the following steps: - Open vi on the board. - Paste a text file (~150 characters). - Save the file, then repeat the process. - Compare the sha256sum of the saved files. The checksums do not match due to missing characters or entire lines. Fix this by restoring the RXTL value to 1 when the UART is used as a console. This ensures timely RX interrupts and reliable data reception in console mode. With this change, pasted content is saved correctly, and checksums are always consistent.

2025-06-24userns and mnt_idmap leak in open_tree_attr(2)Al Viro
Once want_mount_setattr() has returned a positive, it does require finish_mount_kattr() to release ->mnt_userns. Failing do_mount_setattr() does not change that. As the result, we can end up leaking userns and possibly mnt_idmap as well.
