[PATCH v1] can: j1939: j1939_tp_cmd_recv(): check the dst address of TP.CM_BAM

by Oleksij Rempel

From: Zhang Changzhong <zhangchangzhong(a)huawei.com> commit 164051a6ab5445bd97f719f50b16db8b32174269 upstream. The TP.CM_BAM message must be sent to the global address [1], so add a check to drop TP.CM_BAM sent to a non-global address. Without this patch, the receiver will treat the following packets as normal RTS/CTS transport: 18EC0102#20090002FF002301 18EB0102#0100000000000000 18EB0102#020000FFFFFFFFFF [1] SAE-J1939-82 2015 A.3.3 Row 1.

arm64: dts: mcbin: support 2W SFP modules

by Christian Lamparter

commit 05abc6a5dec2a8c123a50235ecd1ad8d75ffa7b4 upstream please consider adding the patch to the 5.4's stable release. (Tested it with patch, where it applies cleanly.) Reason: The commit message of the patch states that it is: "Allow the SFP cages to be used with 2W SFP modules." This was Reported by: 照山周一郎 <teruyama(a)springboard-inc.jp> in his openwrt github PR [0]. Based on the reporters' e-mails in a related thread on the OpenWrt mailinglist [1]. This aforementioned patch is required to get the popular (in Japan) SFP module "NTT OCU" working. Thanks, Christian Lamparter [0] <https://github.com/openwrt/openwrt/pull/4803> [1] <https://patchwork.ozlabs.org/project/openwrt/patch/1638108130-24432-1-git-s…>

[REGRESSION] Kernel 5.15 reboots / freezes upon ifup/ifdown

by Stefan Dietrich

Summary: When attempting to rise or shut down a NIC manually or via network-manager under 5.15, the machine reboots or freezes. Occurs with: 5.15.4-051504-generic and earlier 5.15 mainline ( https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.15.4/) as well as liquorix flavours. Does not occur with: 5.14 and 5.13 (both with various flavours) Hi all, I'm experiencing a severe bug that causes the machine to reboot or freeze when trying to login and/or rise/shutdown a NIC. Here's a brief description of scenarios I've tested: Scenario 1: enp6s0 managed manually using /etc/networking/interfaces, DHCP a. Issuing ifdown enp6s0 in terminal will throw "/etc/resolvconf/update.d/libc: Warning: /etc/resolv.conf is not a symbolic link to /run/resolvconf/resolv.conf" and cause the machine to reboot after ~10s of showing a blinking cursor b. Issuing shutdown -h now or trying to shutdown/reboot machine via GUI: shutdown will stop on "stop job is running for ifdown enp6s0" and after approx. 10..15s the countdown freezes. Repeated ALT-SysReq-REISUB does not reboot the machine, a hard reset is required. -- Scenario 2: enp6s0 managed manually using /etc/networking/interfaces, STATIC a. Issuing ifdown enp6s0 in terminal will throw "send_packet: Operation not permitted dhclient.c:3010: Failed to send 300 byte long packet over fallback interface." and cause the machine to reboot after ~10s of blinking cursor. b. Issuing shutdown -h now or trying to shutdown or reboot machine via GUI: shutdown will stop on "stop job is running for ifdown enp6s0" and after approx. 10..15s the countdown freezes. Repeated ALT-SysReq-REISUB does not reboot the machine, a hard reset is required. -- Scenario 3: enp6s0 managed by network manager a. After booting and logging in either via GUI or TTY, the display will stay blank and only show a blinking cursor and then freeze after 5..10s. ALT-SysReq-REISUB does not reboot the machine, a hard reset is required. -- Here's a snippet from the journal for Scenario 1a: Nov 21 10:39:25 computer sudo[5606]: user : TTY=pts/0 ; PWD=/home/user ; USER=root ; COMMAND=/usr/sbin/ifdown enp6s0 Nov 21 10:39:25 computer sudo[5606]: pam_unix(sudo:session): session opened for user root by (uid=0) -- Reboot -- Nov 21 10:40:14 computer systemd-journald[478]: Journal started -- I'm running Alder Lake i9 12900K but I have E-cores disabled in BIOS. Here are some more specs with working kernel: $ inxi -bxz System: Kernel: 5.14.0-19.2-liquorix-amd64 x86_64 bits: 64 compiler: N/A Desktop: Xfce 4.16.3 Distro: Ubuntu 20.04.3 LTS (Focal Fossa) Machine: Type: Desktop System: ASUS product: N/A v: N/A serial: N/A Mobo: ASUSTeK model: ROG STRIX Z690-A GAMING WIFI D4 v: Rev 1.xx serial: <filter> UEFI [Legacy]: American Megatrends v: 0707 date: 11/10/2021 CPU: 8-Core: 12th Gen Intel Core i9-12900K type: MT MCP arch: N/A speed: 5381 MHz max: 3201 MHz Graphics: Device-1: NVIDIA vendor: Gigabyte driver: nvidia v: 470.86 bus ID: 01:00.0 Display: server: X.Org 1.20.11 driver: nvidia tty: N/A Message: Unable to show advanced data.

Aborted tests ------------- Tests that didn't complete running successfully are marked with ⚡⚡⚡. If this was caused by an infrastructure issue, we try to mark that explicitly in the report. Waived tests ------------ If the test run included waived tests, they are marked with 🚧. Such tests are executed but their results are not taken into account. Tests are waived when their results are not reliable enough, e.g. when they're just introduced or are being fixed. Testing timeout --------------- We aim to provide a report within reasonable timeframe. Tests that haven't finished running yet are marked with ⏱. Targeted tests -------------- Test runs for patches always include a set of base tests, plus some tests chosen based on the file paths modified by the patch. The latter are called "targeted tests". If no targeted tests are run, that means no patch-specific tests are available. Please, consider contributing a targeted test for related patches to increase test coverage.

[PATCH rcu 3/6] tools/nolibc: fix incorrect truncation of exit code

by Paul E. McKenney

From: Willy Tarreau <w(a)1wt.eu> Ammar Faizi reported that our exit code handling is wrong. We truncate it to the lowest 8 bits but the syscall itself is expected to take a regular 32-bit signed integer, not an unsigned char. It's the kernel that later truncates it to the lowest 8 bits. The difference is visible in strace, where the program below used to show exit(255) instead of exit(-1): int main(void) { return -1; } This patch applies the fix to all archs. x86_64, i386, arm64, armv7 and mips were all tested and confirmed to work fine now. Risc-v was not tested but the change is trivial and exactly the same as for other archs.
