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.

2020-05-31checkpatch/coding-style: deprecate 80-column warningJoe Perches1-9/+14
Yes, staying withing 80 columns is certainly still _preferred_. But it's not the hard limit that the checkpatch warnings imply, and other concerns can most certainly dominate. Increase the default limit to 100 characters. Not because 100 characters is some hard limit either, but that's certainly a "what are you doing" kind of value and less likely to be about the occasional slightly longer lines. Miscellanea: - to avoid unnecessary whitespace changes in files, checkpatch will no longer emit a warning about line length when scanning files unless --strict is also used - Add a bit to coding-style about alignment to open parenthesis Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2020-05-30ramoops: Add "max-reason" optional field to ramoops DT nodePavel Tatashin1-2/+11
Currently, it is only possible to get kmsg dumps for panic and oops, or just panic, via "no-dump-oops". With "max-reason" it is possible to dump messages for other kmsg_dump events, for example emerg and shutdown.

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.

2020-05-29spi: Convert DW SPI binding to DT schemaSerge Semin3-73/+133
Modern device tree bindings are supposed to be created as YAML-files in accordance with dt-schema. This commit replaces two DW SPI legacy bare text bindings with YAML file. As before the bindings file states that the corresponding dts node is supposed to be compatible either with generic DW APB SSI controller or with Microsemi/Amazon/Renesas/Intel vendors-specific controllers, to have registers, interrupts and clocks properties. Though in case of Microsemi version of the controller there must be two registers resources specified. Properties like clock-names, reg-io-width, cs-gpio, num-cs, DMA and slave device sub-nodes are optional.

2020-05-28hwmon: Add Baikal-T1 PVT sensor driverSerge Semin2-0/+118
Baikal-T1 SoC provides an embedded process, voltage and temperature sensor to monitor an internal SoC environment (chip temperature, supply voltage and process monitor) and on time detect critical situations, which may cause the system instability and even damages. The IP-block is based on the Analog Bits PVT sensor, but is equipped with a dedicated control wrapper, which provides a MMIO registers-based access to the sensor core functionality (APB3-bus based) and exposes an additional functions like thresholds/data ready interrupts, its status and masks, measurements timeout. All of these is used to create a hwmon driver being added to the kernel by this commit. The driver implements support for the hardware monitoring capabilities of Baikal-T1 process, voltage and temperature sensors. PVT IP-core consists of one temperature and four voltage sensors, each of which is implemented as a dedicated hwmon channel config. The driver can optionally provide the hwmon alarms for each sensor the PVT controller supports. The alarms functionality is made compile-time configurable due to the hardware interface implementation peculiarity, which is connected with an ability to convert data from only one sensor at a time. Additional limitation is that the controller performs the thresholds checking synchronously with the data conversion procedure. Due to these limitations in order to have the hwmon alarms automatically detected the driver code must switch from one sensor to another, read converted data and manually check the threshold status bits. Depending on the measurements timeout settings this design may cause additional burden on the system performance. By default if the alarms kernel config is disabled the data conversion is performed by the driver on demand when read operation is requested via corresponding _input-file.

2020-05-21kernel/printk: add kmsg SEEK_CUR handlingBruno Meneguele1-0/+5
Userspace libraries, e.g. glibc's dprintf(), perform a SEEK_CUR operation over any file descriptor requested to make sure the current position isn't pointing to junk due to previous manipulation of that same fd. And whenever that fd doesn't have support for such operation, the userspace code expects -ESPIPE to be returned. However, when the fd in question references the /dev/kmsg interface, the current kernel code state returns -EINVAL instead, causing an unexpected behavior in userspace: in the case of glibc, when -ESPIPE is returned it gets ignored and the call completes successfully, while returning -EINVAL forces dprintf to fail without performing any action over that fd: if (_IO_SEEKOFF (fp, (off64_t)0, _IO_seek_cur, _IOS_INPUT|_IOS_OUTPUT) == _IO_pos_BAD && errno != ESPIPE) return NULL; With this patch we make sure to return the correct value when SEEK_CUR is requested over kmsg and also add some kernel doc information to formalize this behavior.

2020-05-19fscrypt: add support for IV_INO_LBLK_32 policiesEric Biggers1-4/+29
The eMMC inline crypto standard will only specify 32 DUN bits (a.k.a. IV bits), unlike UFS's 64. IV_INO_LBLK_64 is therefore not applicable, but an encryption format which uses one key per policy and permits the moving of encrypted file contents (as f2fs's garbage collector requires) is still desirable. To support such hardware, add a new encryption format IV_INO_LBLK_32 that makes the best use of the 32 bits: the IV is set to 'SipHash-2-4(inode_number) + file_logical_block_number mod 2^32', where the SipHash key is derived from the fscrypt master key. We hash only the inode number and not also the block number, because we need to maintain contiguity of DUNs to merge bios. Unlike with IV_INO_LBLK_64, with this format IV reuse is possible; this is unavoidable given the size of the DUN. This means this format should only be used where the requirements of the first paragraph apply. However, the hash spreads out the IVs in the whole usable range, and the use of a keyed hash makes it difficult for an attacker to determine which files use which IVs. Besides the above differences, this flag works like IV_INO_LBLK_64 in that on ext4 it is only allowed if the stable_inodes feature has been enabled to prevent inode numbers and the filesystem UUID from changing.

2020-05-19fscrypt: support test_dummy_encryption=v2Eric Biggers1-1/+5
v1 encryption policies are deprecated in favor of v2, and some new features (e.g. encryption+casefolding) are only being added for v2. Therefore, the "test_dummy_encryption" mount option (which is used for encryption I/O testing with xfstests) needs to support v2 policies. To do this, extend its syntax to be "test_dummy_encryption=v1" or "test_dummy_encryption=v2". The existing "test_dummy_encryption" (no argument) also continues to be accepted, to specify the default setting -- currently v1, but the next patch changes it to v2. To cleanly support both v1 and v2 while also making it easy to support specifying other encryption settings in the future (say, accepting "$contents_mode:$filenames_mode:v2"), make ext4 and f2fs maintain a pointer to the dummy fscrypt_context rather than using mount flags. To avoid concurrency issues, don't allow test_dummy_encryption to be set or changed during a remount. (The former restriction is new, but xfstests doesn't run into it, so no one should notice.) Tested with 'gce-xfstests -c {ext4,f2fs}/encrypt -g auto'. On ext4, there are two regressions, both of which are test bugs: ext4/023 and ext4/028 fail because they set an xattr and expect it to be stored inline, but the increase in size of the fscrypt_context from 24 to 40 bytes causes this xattr to be spilled into an external block.

2020-05-15bpf: Restrict bpf_trace_printk()'s %s usage and add %pks, %pus specifierDaniel Borkmann1-0/+14
Usage of plain %s conversion specifier in bpf_trace_printk() suffers from the very same issue as bpf_probe_read{,str}() helpers, that is, it is broken on archs with overlapping address ranges. While the helpers have been addressed through work in 6ae08ae3dea2 ("bpf: Add probe_read_{user, kernel} and probe_read_{user, kernel}_str helpers"), we need an option for bpf_trace_printk() as well to fix it. Similarly as with the helpers, force users to make an explicit choice by adding %pks and %pus specifier to bpf_trace_printk() which will then pick the corresponding strncpy_from_unsafe*() variant to perform the access under KERNEL_DS or USER_DS. The %pk* (kernel specifier) and %pu* (user specifier) can later also be extended for other objects aside strings that are probed and printed under tracing, and reused out of other facilities like bpf_seq_printf() or BTF based type printing. Existing behavior of %s for current users is still kept working for archs where it is not broken and therefore gated through CONFIG_ARCH_HAS_NON_OVERLAPPING_ADDRESS_SPACE. For archs not having this property we fall-back to pick probing under KERNEL_DS as a sensible default.
