Hi,
CVE-2021-39648: usb: gadget: configfs: Fix use-after-free issue with udc_nameI created a patch which revise this issue. I attached this mail.

It's this week's CVE report. This week reported ten new CVEs and two of them aren't fixed in the mainline yet. * New CVEs CVE-2021-0961: In quota_proc_write of xt_quota2.c, there is a possible way to read kernel memory due to uninitialized data CVSS v3 score is not provided This bug is fixed in Android kernel. There is three commits to fix this bug. https://android.googlesource.com/kernel/common/+/e113eb454e92 https://android.googlesource.com/kernel/common/+/60a4c35570d9 https://android.googlesource.com/kernel/common/+/4b05a506bda0 These commit modified net/netfilter/xt_quota2.c which is Android specific source. So this CVE is Android specific bug. The mainline and stable kernels aren't affected. Fixed status The mainline and stable kernels aren't affected. CVE-2021-39648: usb: gadget: configfs: Fix use-after-free issue with udc_name CVSS v3 score is not provided 4.4 kernel gadget_dev_desc_UDC_show() is bit different from later kernel versions.

Re: [PATCH 5.10.y-cip 0/7] Add binding and SoC identification for Renesas RZ/G2L SoC and Renesas RZ/G2L SMARC EVK
Nobuhiro Iwamatsu
Hi all,
I think I need to add the board to LAB first. Of course, source code reviews andI have reviewed patches and they look okay to me. I'll proceed withWe don't have any boards in the CIP labs yet, but there is a plan to add some. build tests are possible. And If my understand is correctoly, I think this is a new board that is not on the reference board list. I don't think this has been discussed at TSC. I think it needs to be on the agenda at TSC, whether it's a reference board for the 5.10-cip kernel.

[PATCH 5.10.y-cip 0/7] Add binding and SoC identification for Renesas RZ/G2L SoC and Renesas RZ/G2L SMARC EVK
Lad Prabhakar
Hi All,
This patch series adds initial support for Renesas RZ/G2L SoC [0] and Renesas RZ/G2L SMARC EVK [1]. The RZ/G2L microprocessor includes a Cortex-A55 (1.2 GHz) CPU, 16-bit DDR3L/DDR4 interface, 3D graphics engine with Arm Mali-G31 and video codec (H.264). It also has many interfaces such as camera input, display output, USB 2.0, and Gbit-Ether, making it ideal for applications such as entry-class industrial human-machine interfaces (HMIs) and embedded devices with video capabilities. Patches add support for the following: * Documentation for RZ/G2{L,LC,UL} SoC variants * Documentation for Renesas SMARC EVK * SYSC binding doc required for SoC identification * SoC identification support * Enabling ARCH_R9A07G044 in defconfig All the patches have been cherry picked from v5.16-rc5 [0] https://www.renesas.com/us/en/products/microcontrollers-microprocessors/ rz-arm-based-high-end-32-64-bit-mpus/rzg2l-general-purpose-microprocessors-dual- core-arm-cortex-a55-12-ghz-cpus-3d-graphics-and-video-codec [1] https://www.renesas.com/us/en/products/microcontrollers-microprocessors/ rz-arm-based-high-end-32-64-bit-mpus/rtk9744l23s01000be-rzg2l-evaluation-board-kit Cheers, Prabhakar Lad Prabhakar (7): dt-bindings: arm: renesas: Document Renesas RZ/G2UL SoC dt-bindings: arm: renesas: Document Renesas RZ/G2{L,LC} SoC variants dt-bindings: arm: renesas: Document SMARC EVK dt-bindings: power: renesas,rzg2l-sysc: Add DT binding documentation for SYSC controller soc: renesas: Add ARCH_R9A07G044 for the new RZ/G2L SoC's soc: renesas: Add support to read LSI DEVID register of RZ/G2{L,LC} SoC's arm64: defconfig: Enable ARCH_R9A07G044 .../devicetree/bindings/arm/renesas.yaml | 18 ++++++ .../bindings/power/renesas,rzg2l-sysc.yaml | 63 +++++++++++++++++++ arch/arm64/configs/defconfig | 1 + drivers/soc/renesas/Kconfig | 5 ++ drivers/soc/renesas/renesas-soc.c | 33 +++++++++- 5 files changed, 119 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/power/renesas,rzg2l-sysc.yaml -- 2.17.1

Renesas RZ/G2L support for 5.10-cip
Lad Prabhakar
Hi Nobuhiro, Pavel,
I have prepared ~105 patches adding support for Renesas RZ/G2L on 5.10-cip (all patches cherry picked from v5.16-rc5). Is it OK if I bulk post the patches or do you prefer them in chunks(maybe ~25 each)? Cheers, Prabhakar
