[PATCH v4 0/2] media: uvcvideo: Support partial control reads and minor changes

by Ricardo Ribalda

Some cameras do not return all the bytes requested from a control if it can fit in less bytes. Eg: returning 0xab instead of 0x00ab. Support these devices. Also, now that we are at it, improve uvc_query_ctrl() logging. Signed-off-by: Ricardo Ribalda <ribalda(a)chromium.org> --- Changes in v4: - Improve comment. - Keep old likely(ret == size) - Link to v3: https://lore.kernel.org/r/20241118-uvc-readless-v3-0-d97c1a3084d0@chromium.… Changes in v3: - Improve documentation. - Do not change return sequence. - Use dev_ratelimit and dev_warn_once - Link to v2: https://lore.kernel.org/r/20241008-uvc-readless-v2-0-04d9d51aee56@chromium.… Changes in v2: - Rewrite error handling (Thanks Sakari) - Discard 2/3.

[PATCH 5.4/5.10/5.15 0/1] Backport fix for CVE-2023-1075

by Nikita Zhandarovich

This patch addresses an issue of type confusion in tls_is_tx_ready(), as a check for NULL of list_first_entry() return value is wrong. This issue has been given a CVE entry CVE-2023-1075 [1] and is still present in several stable branches. As the flawed function tls_is_tx_ready() is named is_tx_ready() and is situated in another file (specifically, include/net/tls.h) in older kernel versions, fix the error there instead. This adapted backport can be cleanly applied to 5.4, 5.10 and 5.15 branches. [PATCH 5.4/5.10/5.15 1/1] net/tls: tls_is_tx_ready() checked list_entry Use list_first_entry_or_null() instead of list_entry() to properly check for empty lists. Fixes [1]. [1] https://nvd.nist.gov/vuln/detail/cve-2023-1075 [2] https://github.com/torvalds/linux/commit/ffe2a22562444720b05bdfeb999c03e810…

[PATCH v5 0/3] clk: qcom: Add support for multiple power-domains for a clock controller.

by Bryan O'Donoghue

Changes in v5: - In-lines devm_pm_domain_attach_list() in probe() directly - Vlad - Link to v4: https://lore.kernel.org/r/20241127-b4-linux-next-24-11-18-clock-multiple-po… v4: - Adds Bjorn's RB to first patch - Bjorn - Drops the 'd' in "and int" - Bjorn - Amends commit log of patch 3 to capture a number of open questions - Bjorn - Link to v3: https://lore.kernel.org/r/20241126-b4-linux-next-24-11-18-clock-multiple-po… v3: - Fixes commit log "per which" - Bryan - Link to v2: https://lore.kernel.org/r/20241125-b4-linux-next-24-11-18-clock-multiple-po… v2: The main change in this version is Bjorn's pointing out that pm_runtime_* inside of the gdsc_enable/gdsc_disable path would be recursive and cause a lockdep splat. Dmitry alluded to this too. Bjorn pointed to stuff being done lower in the gdsc_register() routine that might be a starting point. I iterated around that idea and came up with patch #3. When a gdsc has no parent and the pd_list is non-NULL then attach that orphan GDSC to the clock controller power-domain list. Existing subdomain code in gdsc_register() will connect the parent GDSCs in the clock-controller to the clock-controller subdomain, the new code here does that same job for a list of power-domains the clock controller depends on. To Dmitry's point about MMCX and MCX dependencies for the registers inside of the clock controller, I have switched off all references in a test dtsi and confirmed that accessing the clock-controller regs themselves isn't required. On the second point I also verified my test branch with lockdep on which was a concern with the pm_domain version of this solution but I wanted to cover it anyway with the new approach for completeness sake. Here's the item-by-item list of changes: - Adds a patch to capture pm_genpd_add_subdomain() result code - Bryan - Changes changelog of second patch to remove singleton and generally to make the commit log easier to understand - Bjorn - Uses demv_pm_domain_attach_list - Vlad - Changes error check to if (ret < 0 && ret != -EEXIST) - Vlad - Retains passing &pd_data instead of NULL - because NULL doesn't do the same thing - Bryan/Vlad - Retains standalone function qcom_cc_pds_attach() because the pd_data enumeration looks neater in a standalone function - Bryan/Vlad - Drops pm_runtime in favour of gdsc_add_subdomain_list() for each power-domain in the pd_list. The pd_list will be whatever is pointed to by power-domains = <> in the dtsi - Bjorn - Link to v1: https://lore.kernel.org/r/20241118-b4-linux-next-24-11-18-clock-multiple-po… v1: On x1e80100 and it's SKUs the Camera Clock Controller - CAMCC has multiple power-domains which power it. Usually with a single power-domain the core platform code will automatically switch on the singleton power-domain for you. If you have multiple power-domains for a device, in this case the clock controller, you need to switch those power-domains on/off yourself. The clock controllers can also contain Global Distributed Switch Controllers - GDSCs which themselves can be referenced from dtsi nodes ultimately triggering a gdsc_en() in drivers/clk/qcom/gdsc.c. As an example: cci0: cci@ac4a000 { power-domains = <&camcc TITAN_TOP_GDSC>; }; This series adds the support to attach a power-domain list to the clock-controllers and the GDSCs those controllers provide so that in the case of the above example gdsc_toggle_logic() will trigger the power-domain list with pm_runtime_resume_and_get() and pm_runtime_put_sync() respectively.

[PATCH v2 6/7] ima: Discard files opened with O_PATH

by Roberto Sassu

From: Roberto Sassu <roberto.sassu(a)huawei.com> According to man open.2, files opened with O_PATH are not really opened. The obtained file descriptor is used to indicate a location in the filesystem tree and to perform operations that act purely at the file descriptor level.

[PATCH] HID: i2c-hid: Revert to using power commands to wake on resume

by Kenny Levinsen

7d6f065de37c ("HID: i2c-hid: Use address probe to wake on resume") replaced the retry of power commands with the dummy read "bus probe" we use on boot which accounts for a necessary delay before retry. This made at least one Weida device (2575:0910 in an ASUS Vivobook S14) very unhappy, as the bus probe despite being successful somehow lead to the following power command failing so hard that the device never lets go of the bus. This means that even retries of the power command would fail on a timeout as the bus remains busy. Remove the bus probe on resume and instead reintroduce retry of the power command for wake-up purposes while respecting the newly established wake-up retry timings.

[PATCH v1] usb: typec: ucsi: Fix completion notifications

by Łukasz Bartosik

OPM PPM LPM | 1.send cmd | | |-------------------------->| | | |-- | | | | 2.set busy bit in CCI | | |<- | | 3.notify the OPM | | |<--------------------------| | | | 4.send cmd to be executed | | |-------------------------->| | | | | | 5.cmd completed | | |<--------------------------| | | | | |-- | | | | 6.set cmd completed | | |<- bit in CCI | | | | | 7.handle notification | | | from point 3, read CCI | | |<--------------------------| | | | | | 8.notify the OPM | | |<--------------------------| | | | | When the PPM receives command from the OPM (p.1) it sets the busy bit in the CCI (p.2), sends notification to the OPM (p.3) and forwards the command to be executed by the LPM (p.4). When the PPM receives command completion from the LPM (p.5) it sets command completion bit in the CCI (p.6) and sends notification to the OPM (p.8). If command execution by the LPM is fast enough then when the OPM starts handling the notification from p.3 in p.7 and reads the CCI value it will see command completion bit and will call complete(). Then complete() might be called again when the OPM handles notification from p.8. This fix replaces test_bit() with test_and_clear_bit() in ucsi_notify_common() in order to call complete() only once per request.

[PATCH 6.1 0/3] Backport fixes for CVE-2024-42155, CVE-2024-42156 and CVE-2024-42158

by Nikita Zhandarovich

This series addresses several s390 driver vulnerabilities related to improper handling of sensitive keys-related material and its lack of proper disposal in stable kernel branches. These issues have been announced as CVE-2024-42155 [1], CVE-2024-42156 [2] and CVE-2024-42158 [4] and fixed in upstream. Another problem named as CVE-2024-42157 [3] has already been successfully backported. All patches have been cherry-picked and are ready to be cleanly applied to 6.1 stable branch. Same series adapted for 6.6 version will follow separately. Backports for 5.10/5.15 have already been sent, see [5]. [PATCH 6.1 1/3] s390/pkey: Use kfree_sensitive() to fix Coccinelle warnings Use kfree_sensitive() instead of kfree() and memzero_explicit(). Fixes CVE-2024-42158. [PATCH 6.1 2/3] s390/pkey: Wipe copies of clear-key structures on failure Properly wipe sensitive key material from stack for IOCTLs that deal with clear-key conversion. Fixes CVE-2024-42156. [PATCH 6.1 3/3] s390/pkey: Wipe copies of protected- and secure-keys Properly wipe key copies from stack for affected IOCTLs. Fixes CVE-2024-42155.
