If the optional "clock-names" property is present, but the optional TXC reference clock is not, "make dtbs_check" complains: ethernet@e6800000: clock-names: ['fck'] is too short Fix this by declaring that a single clock name is valid.

2021-05-04docs: reporting-issues.rst: CC subsystem and maintainers on regressionsThorsten Leemhuis1-19/+30
When reporting a regression, users ideally should CC the subsystem and its maintainers, as that will ensure they get aware of the regression quickly. And if the culprit is known, they should also CC everyone who signed if off; the text mentioned the latter in once place already, but forgot to do so in two other areas where it's relevant. While fixing this also remind readers to check the mailing list archives for issues that need to be reported to a bug tracker, as someone might have reported it by mail only. All of this got triggered by a recent report where these changes would have made a difference.

git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security Pull Landlock LSM from James Morris: "Add Landlock, a new LSM from Mickaël Salaün. Briefly, Landlock provides for unprivileged application sandboxing. From Mickaël's cover letter: "The goal of Landlock is to enable to restrict ambient rights (e.g. global filesystem access) for a set of processes. Because Landlock is a stackable LSM [1], it makes possible to create safe security sandboxes as new security layers in addition to the existing system-wide access-controls. This kind of sandbox is expected to help mitigate the security impact of bugs or unexpected/malicious behaviors in user-space applications. Landlock empowers any process, including unprivileged ones, to securely restrict themselves. Landlock is inspired by seccomp-bpf but instead of filtering syscalls and their raw arguments, a Landlock rule can restrict the use of kernel objects like file hierarchies, according to the kernel semantic. Landlock also takes inspiration from other OS sandbox mechanisms: XNU Sandbox, FreeBSD Capsicum or OpenBSD Pledge/Unveil. In this current form, Landlock misses some access-control features. This enables to minimize this patch series and ease review. This series still addresses multiple use cases, especially with the combined use of seccomp-bpf: applications with built-in sandboxing, init systems, security sandbox tools and security-oriented APIs [2]" The cover letter and v34 posting is here: https://lore.kernel.org/linux-security-module/20210422154123.13086-1-mic@digikod.net/ See also: https://landlock.io/ This code has had extensive design discussion and review over several years" Link: https://lore.kernel.org/lkml/50db058a-7dde-441b-a7f9-f6837fe8b69f@schaufler-ca.com/ [1] Link: https://lore.kernel.org/lkml/f646e1c7-33cf-333f-070c-0a40ad0468cd@digikod.net/ [2] * tag 'landlock_v34' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: landlock: Enable user space to infer supported features landlock: Add user and kernel documentation samples/landlock: Add a sandbox manager example selftests/landlock: Add user space tests landlock: Add syscall implementations arch: Wire up Landlock syscalls fs,security: Add sb_delete hook landlock: Support filesystem access-control LSM: Infrastructure management of the superblock landlock: Add ptrace restrictions landlock: Set up the security framework and manage credentials landlock: Add ruleset and domain management landlock: Add object management

Core changes: - A semantic change to handle pinmux and pinconf in explicit order while up until now we depended on the semantic order in the device tree. The device tree is a functional programming language and does not imply any order, so the right thing is for the pin control core to provide these semantics. - Add a new pinmux-select debugfs file which makes it possible to go in and select functions for a pin manually (iteratively, at the prompt) for debugging purposes. - Fixes to gpio regmap handling for a new pin control driver making use of regmap-gpio. - Use octal permissions on debugfs files. New drivers: - A massive rewrite of the former custom pin control driver for MIPS Broadcom devices to instead use the pin control subsystem. New pin control drivers for BCM6345, BCM6328, BCM6358, BCM6362, BCM6368, BCM63268 and BCM6318 SoC variants are implemented. - Support for PM8350, PM8350B, PM8350C, PMK8350, PMR735A and PMR735B in the Qualcomm PMIC GPIO driver. Also the two GPIOs on PM8008 are supported. - Support for the Rockchip RK3568/RK3566 pin controller. - Support for Ingenic JZ4730, JZ4750, JZ4755, JZ4775 and X2000. - Support for Mediatek MTK8195. - Add a new Xilinx ZynqMP pin control driver. Driver improvements and non-urgent fixes: - Modularization and improvements of the Rockchip drivers. - Some new pins added to the description of new Renesas SoCs. - Clarifications of the GPIO base calculation in the Intel driver. - Fix the function names for the MPP54 and MPP55 pins in the Armada CP110 pin controller. - GPIO wakeup interrupt map for Qualcomm SC7280 and SM8350. - Support for ACPI probing of the Qualcomm SC8180x. - Fix interrupt clear status on rockchip - Fix some missing pins on the Ingenic JZ4770, some semantic fixes for the behaviour of the Ingenic pin controller.
