2026-03-12tty: hvc_iucv: fix off-by-one in number of supported devicesRandy Dunlap1-1/+1
MAX_HVC_IUCV_LINES == HVC_ALLOC_TTY_ADAPTERS == 8. This is the number of entries in: static struct hvc_iucv_private *hvc_iucv_table[MAX_HVC_IUCV_LINES]; Sometimes hvc_iucv_table[] is limited by: (a) if (num > hvc_iucv_devices) // for error detection or (b) for (i = 0; i < hvc_iucv_devices; i++) // in 2 places (so these 2 don't agree; second one appears to be correct to me.) hvc_iucv_devices can be 0..8. This is a counter. (c) if (hvc_iucv_devices > MAX_HVC_IUCV_LINES) If hvc_iucv_devices == 8, (a) allows the code to access hvc_iucv_table[8]. Oops.

2026-03-12tty: serial: samsung_tty: avoid dev_dbg deadlockAlyssa Milburn1-8/+2
commit a05025d0ce72 ("tty: serial: samsung_tty: use standard debugging macros") changed the debug prints to dev_dbg, which can result in deadlocks: s3c24xx_serial_set_termios can be called with the port lock, and then calls dev_dbg, which needs the console mutex. At the same time, s3c24xx_serial_console_write can be called with the console lock (e.g., inside console_unlock), and needs the port lock. To avoid this, move one dev_dbg call and just delete the other.

Add a module parameter to MCP2221 to enfor GPIO mode on the general purpose pins GP0 thru GP3. If I plug a device of this type into my machine, it will use the GP0, GP1, GP2 and GP3 pins for IIO voltage readings by default if CONFIG_IIO is set. However there may be cases where IIO is available but we want to use the GP0 thru GP3 lines for GPIO anyway.

2026-03-12kbuild: Consolidate C dialect optionsNathan Chancellor1-2/+1
Introduce CC_FLAGS_DIALECT to make it easier to update the various places in the tree that rely on the GNU C standard and Microsoft extensions flags atomically. All remaining uses of '-std=gnu11' and '-fms-extensions' are in the tools directory (which has its own build system) and other standalone Makefiles. This will allow the kernel to use a narrower option to enable the Microsoft anonymous tagged structure extension in a simpler manner. Place the CC_FLAGS_DIALECT block after the configuration include (so that a future change can move the selection of the flag to Kconfig) but before the arch/$(SRCARCH)/Makefile include (so that CC_FLAGS_DIALECT is available for use in those Makefiles).

2026-03-12drm/ttm/tests: add a test to exercise ttm_bo_swapoutThadeu Lima de Souza Cascardo2-0/+43
Currently, ttm_bo_swapout is not exercised by the TTM KUnit tests. It used to be exercised until commit 76689eb52667 ("drm/ttm: remove ttm_bo_validate_swapout test"), but that test was removed as it was unreliable due to requiring to allocate half of the system memory. Calling ttm_bo_swapout directly with a single allocated BO, however, does not suffer from that problem, and was able to detect a UAF introduced by commit c06da4b3573a ("drm/ttm: Tidy usage of local variables a little bit"), when built with KASAN. When applying a fix to that UAF, the test passed without any issues.

2026-03-12vsock: add G2H fallback for CIDs not owned by H2G transportAlexander Graf1-0/+13
When no H2G transport is loaded, vsock currently routes all CIDs to the G2H transport (commit 65b422d9b61b ("vsock: forward all packets to the host when no H2G is registered"). Extend that existing behavior: when an H2G transport is loaded but does not claim a given CID, the connection falls back to G2H in the same way. This matters in environments like Nitro Enclaves, where an instance may run nested VMs via vhost-vsock (H2G) while also needing to reach sibling enclaves at higher CIDs through virtio-vsock-pci (G2H). With the old code, any CID > 2 was unconditionally routed to H2G when vhost was loaded, making those enclaves unreachable without setting VMADDR_FLAG_TO_HOST explicitly on every connect. Requiring every application to set VMADDR_FLAG_TO_HOST creates friction: tools like socat, iperf, and others would all need to learn about it. The flag was introduced 6 years ago and I am still not aware of any tool that supports it. Even if there was support, it would be cumbersome to use. The most natural experience is a single CID address space where H2G only wins for CIDs it actually owns, and everything else falls through to G2H, extending the behavior that already exists when H2G is absent. To give user space at least a hint that the kernel applied this logic, automatically set the VMADDR_FLAG_TO_HOST on the remote address so it can determine the path taken via getpeername(). Add a per-network namespace sysctl net.vsock.g2h_fallback (default 1). At 0 it forces strict routing: H2G always wins for CID > VMADDR_CID_HOST, or ENODEV if H2G is not loaded.

2026-03-12drm/xe: implement VM_BIND decompression in vm_bind_ioctlNitin Gote4-9/+87
Implement handling of VM_BIND(..., DECOMPRESS) in xe_vm_bind_ioctl. Key changes: - Parse and record per-op intent (op->map.request_decompress) when the DECOMPRESS flag is present. - Use xe_pat_index_get_comp_en() helper to check if a PAT index has compression enabled via the XE2_COMP_EN bit. - Validate DECOMPRESS preconditions in the ioctl path: - Only valid for MAP ops. - The provided pat_index must select the device's "no-compression" PAT. - Only meaningful on devices with flat CCS and the required XE2+ otherwise return -EOPNOTSUPP. - Use XE_IOCTL_DBG for uAPI sanity checks. - Implement xe_bo_decompress(): For VRAM BOs run xe_bo_move_notify(), reserve one fence slot, schedule xe_migrate_resolve(), and attach the returned fence with DMA_RESV_USAGE_KERNEL. Non-VRAM cases are silent no-ops. - Wire scheduling into vma_lock_and_validate() so VM_BIND will schedule decompression when request_decompress is set. - Handle fault-mode VMs by performing decompression synchronously during the bind process, ensuring that the resolve is completed before the bind finishes. This schedules an in-place GPU resolve (xe_migrate_resolve) for decompression.

The NIX RAS health reporter recovery routine checks nix_af_rvu_int to decide whether to re-enable NIX_AF_RAS interrupts. This is the RVU interrupt status field and is unrelated to RAS events, so the recovery flow may incorrectly skip re-enabling NIX_AF_RAS interrupts. Check nix_af_rvu_ras instead before writing NIX_AF_RAS_ENA_W1S.

The DesignWare I3C master controller ACKs IBIs as soon as a valid Device Address Table (DAT) entry is present. This can create a race between device attachment (after DAA) and the point where the client driver enables IBIs via i3c_device_enable_ibi(). Set DEV_ADDR_TABLE_SIR_REJECT in the DAT entry during attach_i3c_dev() and reattach_i3c_dev() so that IBIs are rejected by default. The bit is managed thereafter by the existing dw_i3c_master_set_sir_enabled() function, which clears it in enable_ibi() after ENEC is issued, and restores it in disable_ibi() after DISEC.

2026-03-12i3c: mipi-i3c-hci: Fallback to software reset when bus disable failsAdrian Hunter1-30/+35
Disruption of the MIPI I3C HCI controller's internal state can cause i3c_hci_bus_disable() to fail when attempting to shut down the bus. In the code paths where bus disable is invoked - bus clean-up and runtime suspend - the controller does not need to remain operational afterward, so a full controller reset is a safe recovery mechanism. Add a fallback to issue a software reset when disabling the bus fails. This ensures the bus is reliably halted even if the controller's state machine is stuck or unresponsive. The fallback is used both during bus clean-up and in the runtime suspend path. In the latter case, ensure interrupts are quiesced after reset.

2026-03-12i3c: mipi-i3c-hci: Fix handling of shared IRQs during early initializationAdrian Hunter1-3/+10
Shared interrupts may fire unexpectedly, including during periods when the controller is not yet fully initialized. Commit b9a15012a1452 ("i3c: mipi-i3c-hci: Add optional Runtime PM support") addressed this issue for the runtime-suspended state, but the same problem can also occur before the bus is enabled for the first time. Ensure the IRQ handler ignores interrupts until initialization is complete by making consistent use of the existing irq_inactive flag. The flag is now set to false immediately before enabling the bus. To guarantee correct ordering with respect to the IRQ handler, protect all transitions of irq_inactive with the same spinlock used inside the handler.
