[PATCH 6.12.y 0/2] Backport support for Telit FN920C04 and FN990B40 modems

by Fabio Porcedda

Hi, these two patches are backports for 6.12.y of the following commits: commit d2b91b3097c693f784393a28801a3885778615df bus: mhi: host: pci_generic: Add Telit FN920C04 modem support commit 00559ba3ae740e7544b48fb509b2b97f56615892 bus: mhi: host: pci_generic: Add Telit FN990B40 modem support The cherry-pick of the original commits don't apply so I made this patches after fixing the conflict. Regards Daniele Palmas (2): bus: mhi: host: pci_generic: Add Telit FN920C04 modem support bus: mhi: host: pci_generic: Add Telit FN990B40 modem support drivers/bus/mhi/host/pci_generic.c | 52 ++++++++++++++++++++++++++++++ 1 file changed, 52 insertions(+) -- 2.52.0

Because gpiochip_add_data successfully done, use err_remove_gpiochip instead of err_free_bitmap to free such as gdev,descs..

please consider to backport "drm/i915/dp: Initialize the source OUI write timestamp always"

by H. Nikolaus Schaller

Adding this patch solves an observed 5 minutes wait delay issue with stable kernels (up to v6.12) on my AcePC T11 (with Atom Z8350 Cherry Trail). Commit is 5861258c4e6a("drm/i915/dp: Initialize the source OUI write timestamp always") resp. https://patchwork.freedesktop.org/patch/621660/ It apparently appeared upstream with v6.13-rc1 but got not backported. BR and thanks, Nikolaus

Linux 5.4.302

by Greg Kroah-Hartman

I'm announcing the release of the 5.4.302 kernel. This is the LAST 5.4.y release. It is now end-of-life and should not be used by anyone, anymore. As of this point in time, there are 1539 documented unfixed CVEs for this kernel branch, and that number will only increase over time as more CVEs get assigned for kernel bugs. All users of the 5.4 kernel series must upgrade to a newer branch as this point in time. The updated 5.4.y git tree can be found at: git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-5.4.y and can be browsed at the normal kernel.org git web browser:

[PATCH 6.1.y] HID: core: Harden s32ton() against conversion to 0 bits

by jetlan9＠163.com

From: Alan Stern <stern(a)rowland.harvard.edu> [ Upstream commit a6b87bfc2ab5bccb7ad953693c85d9062aef3fdd ] Testing by the syzbot fuzzer showed that the HID core gets a shift-out-of-bounds exception when it tries to convert a 32-bit quantity to a 0-bit quantity. Ideally this should never occur, but there are buggy devices and some might have a report field with size set to zero; we shouldn't reject the report or the device just because of that. Instead, harden the s32ton() routine so that it returns a reasonable result instead of crashing when it is called with the number of bits set to 0 -- the same as what snto32() does.

[PATCH net] atm: mpoa: Fix UAF on qos_head list in procfs

by Minseong Kim

The global QoS list 'qos_head' in net/atm/mpc.c is accessed from the /proc/net/atm/mpc procfs interface without proper synchronization. The read-side seq_file show path (mpc_show() -> atm_mpoa_disp_qos()) walks qos_head without any lock, while the write-side path (proc_mpc_write() -> parse_qos() -> atm_mpoa_delete_qos()) can unlink and kfree() entries immediately. Concurrent read/write therefore leads to a use-after-free. This risk is already called out in-tree: /* this is buggered - we need locking for qos_head */ Fix this by adding a mutex to protect all qos_head list operations. A mutex is used (instead of a spinlock) because atm_mpoa_disp_qos() invokes seq_printf(), which may sleep. The fix: - Adds qos_mutex protecting qos_head - Introduces __atm_mpoa_search_qos() requiring the mutex - Serializes add/search/delete/show/cleanup on qos_head - Re-checks qos_head under lock in add path to avoid duplicates under concurrent additions - Uses a single-exit pattern in delete for clarity Note: atm_mpoa_search_qos() still returns an unprotected pointer; callers must ensure the entry is not freed while using it, or hold qos_mutex.
