The userspace program could pass any values to the driver through ioctl() interface. If the driver doesn't check the value of 'pixclock', it may cause divide error.

2022-04-11drm/i915: Sunset igpu legacy mmap support based on GRAPHICS_VER_FULLMatt Roper1-1/+1
The intent of the version check in the mmap ioctl was to maintain support for existing platforms (i.e., ADL/RPL and earlier), but drop support on all future igpu platforms. As we've seen on the dgpu side, the hardware teams are using a more fine-grained numbering system for IP version numbers these days, so it's possible the version number associated with our next igpu could be some form of "12.xx" rather than 13 or higher. Comparing against the full ver.release number will ensure the intent of the check is maintained no matter what numbering the hardware teams settle on.

Commit f3e7dae323ab ("ARM: dts: imx6qdl: add enet_out clk support") added another item to the list of clocks for the fec device. As imx6dl-eckelmann-ci4x10.dts only overwrites clocks, but not clock-names this resulted in an inconsistency with clocks having one item more than clock-names. Also overwrite clock-names with the same value as in imx6qdl.dtsi. This is a no-op today, but prevents similar inconsistencies if the soc file will be changed in a similar way in the future.

2022-04-10libbpf: Fix a bug with checking bpf_probe_read_kernel() support in old kernelsRunqing Yang1-1/+1
Background: Libbpf automatically replaces calls to BPF bpf_probe_read_{kernel,user} [_str]() helpers with bpf_probe_read[_str](), if libbpf detects that kernel doesn't support new APIs. Specifically, libbpf invokes the probe_kern_probe_read_kernel function to load a small eBPF program into the kernel in which bpf_probe_read_kernel API is invoked and lets the kernel checks whether the new API is valid. If the loading fails, libbpf considers the new API invalid and replaces it with the old API. static int probe_kern_probe_read_kernel(void) { struct bpf_insn insns[] = { BPF_MOV64_REG(BPF_REG_1, BPF_REG_10), /* r1 = r10 (fp) */ BPF_ALU64_IMM(BPF_ADD, BPF_REG_1, -8), /* r1 += -8 */ BPF_MOV64_IMM(BPF_REG_2, 8), /* r2 = 8 */ BPF_MOV64_IMM(BPF_REG_3, 0), /* r3 = 0 */ BPF_RAW_INSN(BPF_JMP | BPF_CALL, 0, 0, 0, BPF_FUNC_probe_read_kernel), BPF_EXIT_INSN(), }; int fd, insn_cnt = ARRAY_SIZE(insns); fd = bpf_prog_load(BPF_PROG_TYPE_KPROBE, NULL, "GPL", insns, insn_cnt, NULL); return probe_fd(fd); } Bug: On older kernel versions [0], the kernel checks whether the version number provided in the bpf syscall, matches the LINUX_VERSION_CODE. If not matched, the bpf syscall fails. eBPF However, the probe_kern_probe_read_kernel code does not set the kernel version number provided to the bpf syscall, which causes the loading process alwasys fails for old versions. It means that libbpf will replace the new API with the old one even the kernel supports the new one. Solution: After a discussion in [1], the solution is using BPF_PROG_TYPE_TRACEPOINT program type instead of BPF_PROG_TYPE_KPROBE because kernel does not enfoce version check for tracepoint programs. I test the patch in old kernels (4.18 and 4.19) and it works well.

2022-04-11xfs: Add XFS messages to printk indexJonathan Lassoff2-10/+21
In order for end users to quickly react to new issues that come up in production, it is proving useful to leverage the printk indexing system. This printk index enables kernel developers to use calls to printk() with changeable format strings (as they always have; no change of expectations), while enabling end users to examine format strings to detect changes. Since end users are using regular expressions to match messages printed through printk(), being able to detect changes in chosen format strings from release to release provides a useful signal to review printk()-matching regular expressions for any necessary updates. So that detailed XFS messages are captures by this printk index, this patch wraps the xfs_<level> and xfs_alert_tag functions.

This patch adds the device tree to support Toradex Verdin iMX8M Plus [1] a computer on module which can be used on different carrier boards. The module consists of an NXP i.MX 8M Plus family SoC (either i.MX 8M Plus Quad or 8M Plus QuadLite), a PCA9450C PMIC, a Gigabit Ethernet PHY, 1, 2, 4 or 8 GB of LPDDR4 RAM, an eMMC, a TLA2024 ADC, an I2C EEPROM, an RX8130 RTC, an optional I2C temperature sensor plus an optional Bluetooth/Wi-Fi module. Anything that is not self-contained on the module is disabled by default. The device tree for the Dahlia includes the module's device tree and enables the supported peripherals of the carrier board. The device tree for the Verdin Development Board includes the module's device tree as well as the Dahlia one as it is a superset and supports almost all peripherals available. So far there is no display functionality supported at all but basic console UART, USB host, eMMC and Ethernet functionality work fine.

2022-04-11arm64: dts: ls1028a: default to OTG mode for USBMichael Walle4-3/+4
At the moment, the dtsi will force the dr_mode to host. This is problematic because it will always turn on the Vbus voltage regardless if the port is host or device. This might lead to a "shortcut" between the two USB endpoints because both might have their Vbus supplies enabled. Therefore, the default should be "otg" for any ports which aren't host only (from a SoC point of view) and have a user of the dtsi file overwrite that explicitly. Move the 'dr_mode = "host";' into the board dts. Now that the dtsi doesn't set the dr_mode anymore, we can also drop the 'dr_mode = "otg";' in the board dts because that is the default value if dr_mode is not set.

2022-04-11arm64: dts: ls1028a: sl28: use ocelot-8021q tagging by defaultMichael Walle1-0/+8
Enable the ocelot-8021q tagger by default which supports ethernet flow control. The new default is set in the common board dtsi. The actual switch node is enabled on a per board variant basis. Because of this we set the new tagger default for both internal ports and a particular variant is free to choose among the two port.
