2020-06-01mtd: Support kmsg dumper based on pstore/blkWeiXiong Liao1-2/+7
This introduces mtdpstore, which is similar to mtdoops but more powerful. It uses pstore/blk, and aims to store panic and oops logs to a flash partition, where pstore can later read back and present as files in the mounted pstore filesystem. To make mtdpstore work, the "blkdev" of pstore/blk should be set as MTD device name or MTD device number. For more details, see Documentation/admin-guide/pstore-blk.rst This solves a number of issues: - Work duplication: both of pstore and mtdoops do the same job storing panic/oops log. They have very similar logic, registering to kmsg dumper and storing logs to several chunks one by one. - Layer violations: drivers should provides methods instead of polices. MTD should provide read/write/erase operations, and allow a higher level drivers to provide the chunk management, kmsg dump configuration, etc. - Missing features: pstore provides many additional features, including presenting the logs as files, logging dump time and count, and supporting other frontends like pmsg, console, etc. Signed-off-by: WeiXiong Liao <liaoweixiong@allwinnertech.com> Link: https://lore.kernel.org/lkml/20200511233229.27745-11-keescook@chromium.org/ Link: https://lore.kernel.org/r/1589266715-4168-1-git-send-email-liaoweixiong@allwinnertech.com Signed-off-by: Kees Cook <keescook@chromium.org>
2020-06-01pstore/blk: Support non-block storage devicesWeiXiong Liao1-4/+13
Add support for non-block devices (e.g. MTD). A non-block driver calls pstore_blk_register_device() to register iself. In addition, pstore/zone is updated to handle non-block devices, where an erase must be done before a write. Without this, there is no way to remove records stored to an MTD.

2020-05-30pstore/ram: Introduce max_reason and convert dump_oopsKees Cook1-4/+10
Now that pstore_register() can correctly pass max_reason to the kmesg dump facility, introduce a new "max_reason" module parameter and "max-reason" Device Tree field. The "dump_oops" module parameter and "dump-oops" Device Tree field are now considered deprecated, but are now automatically converted to their corresponding max_reason values when present, though the new max_reason setting has precedence. For struct ramoops_platform_data, the "dump_oops" member is entirely replaced by a new "max_reason" member, with the only existing user updated in place. Additionally remove the "reason" filter logic from ramoops_pstore_write(), as that is not specifically needed anymore, though technically this is a change in behavior for any ramoops users also setting the printk.always_kmsg_dump boot param, which will cause ramoops to behave as if max_reason was set to KMSG_DUMP_MAX.

2020-05-28cgroup: add cpu.stat file to root cgroupBoris Burkov1-4/+2
Currently, the root cgroup does not have a cpu.stat file. Add one which is consistent with /proc/stat to capture global cpu statistics that might not fall under cgroup accounting. We haven't done this in the past because the data are already presented in /proc/stat and we didn't want to add overhead from collecting root cgroup stats when cgroups are configured, but no cgroups have been created. By keeping the data consistent with /proc/stat, I think we avoid the first problem, while improving the usability of cgroups stats. We avoid the second problem by computing the contents of cpu.stat from existing data collected for /proc/stat anyway.

2020-05-22x86/tsc: Add tsc_early_khz command line parameterKrzysztof Piecuch1-0/+6
Changing base clock frequency directly impacts TSC Hz but not CPUID.16h value. An overclocked CPU supporting CPUID.16h and with partial CPUID.15h support will set TSC KHZ according to "best guess" given by CPUID.16h relying on tsc_refine_calibration_work to give better numbers later. tsc_refine_calibration_work will refuse to do its work when the outcome is off the early TSC KHZ value by more than 1% which is certain to happen on an overclocked system. Fix this by adding a tsc_early_khz command line parameter that makes the kernel skip early TSC calibration and use the given value instead. This allows the user to provide the expected TSC frequency that is closer to reality than the one reported by the hardware, enabling tsc_refine_calibration_work to do meaningful error checking.

2020-05-21dm zoned: metadata version 2Hannes Reinecke1-7/+27
Implement handling for metadata version 2. The new metadata adds a label and UUID for the device mapper device, and additional UUID for the underlying block devices. It also allows for an additional regular drive to be used for emulating random access zones. The emulated zones will be placed logically in front of the zones from the zoned block device, causing the superblocks and metadata to be stored on that device. The first zone of the original zoned device will be used to hold another, tertiary copy of the metadata; this copy carries a generation number of 0 and is never updated; it's just used for identification.

The goal is to be able to inherit the initial devconf parameters from the current netns, ie the netns where this new netns has been created. This is useful in a containers environment where /proc/sys is read only. For example, if a pod is created with specifics devconf parameters and has the capability to create netns, the user expects to get the same parameters than his 'init_net', which is not the real init_net in this case.
