[PATCH v6 4/4] ring-buffer: Use flush_kernel_vmap_range() over flush_dcache_folio()

by Steven Rostedt

From: Steven Rostedt <rostedt(a)goodmis.org> Some architectures do not have data cache coherency between user and kernel space. For these architectures, the cache needs to be flushed on both the kernel and user addresses so that user space can see the updates the kernel has made. Instead of using flush_dcache_folio() and playing with virt_to_folio() within the call to that function, use flush_kernel_vmap_range() which takes the virtual address and does the work for those architectures that need it. This also fixes a bug where the flush of the reader page only flushed one page. If the sub-buffer order is 1 or more, where the sub-buffer size would be greater than a page, it would miss the rest of the sub-buffer content, as the "reader page" is not just a page, but the size of a sub-buffer.

[PATCH v4 1/1] usbnet:fix NPE during rx_complete

by Ying Lu

From: Ying Lu <luying1(a)xiaomi.com> Missing usbnet_going_away Check in Critical Path. The usb_submit_urb function lacks a usbnet_going_away validation, whereas __usbnet_queue_skb includes this check. This inconsistency creates a race condition where: A URB request may succeed, but the corresponding SKB data fails to be queued. Subsequent processes: (e.g., rx_complete → defer_bh → __skb_unlink(skb, list)) attempt to access skb->next, triggering a NULL pointer dereference (Kernel Panic).

[PATCH] Bluetooth: Revert vendor-specific ISO classification for

by Sean Rhodes

From ccabbdd36dacc3e03ed819b4b050ebcc1978e311 Mon Sep 17 00:00:00 2001 From: Sean Rhodes <sean(a)starlabs.systems> Date: Wed, 2 Apr 2025 09:05:17 +0100 Subject: [PATCH] Bluetooth: Revert vendor-specific ISO classification for non-offload cards This reverts commit f25b7fd36cc3a850e006aed686f5bbecd200de1b. The commit introduces vendor-specific classification of ISO data, but breaks Bluetooth functionality on certain Intel cards that do not support audio offload, such as the 9462. Affected devices are unable to discover new Bluetooth peripherals, and previously paired devices fail to reconnect. This issue does not affect newer cards (e.g., AX201+) that support audio offload. A conditional check using AOLD() could be used in the future to reintroduce this behavior only on supported hardware.

[PATCH v2] HID: wacom: fix shift OOB in kfifo allocation for zero pktlen

by Qasim Ijaz

During wacom_parse_and_register() the code calls wacom_devm_kfifo_alloc to allocate a fifo. During this operation it passes kfifo_alloc a fifo_size of 0. Kfifo attempts to round the size passed to it to the next power of 2 via roundup_pow_of_two (queue-type data structures do this to maintain efficiency of operations). However during this phase a problem arises when the roundup_pow_of_two() function utilises a shift exponent of fls_long(n-1), where n is the fifo_size. Since n is 0 in this case and n is also an unsigned long, doing n-1 causes unsigned integer wrap-around to occur making the fifo_size 4294967295. So the code effectively does fls_long(4294967295) which results in 64. Returning back to roundup_pow_of_two(), the code utilises a shift exponent of 64. When a shift exponent of 64 is used on a 64-bit type such as 1UL it results in a shift-out-of-bounds. The root cause of the issue seems to stem from insufficient validation of wacom_compute_pktlen(), since in this case the fifo_size comes from wacom_wac->features.pktlen. During wacom_parse_and_register() the wacom_compute_pktlen() function sets the pktlen as 0. To fix this, we should handle cases where wacom_compute_pktlen() results in 0.
