2022-02-10net: mac802154: Set durations automaticallyMiquel Raynal1-0/+2
As depicted in the IEEE 802.15.4 specification, modulation/bands are tight to a number of page/channels so we can for most of them derive the durations automatically. The two locations that must call this new helper to set the variou symbol durations are: - when manually requesting a channel change though the netlink interface - at PHY creation, once the device driver has set the default page/channel If an information is missing, the symbol duration is not touched, a debug message is eventually printed. This keeps the compatibility with the unconverted drivers for which it was too complicated for me to find their precise information. If they initially provided a symbol duration, it would be kept. If they don't, the symbol duration value is left untouched. Once the symbol duration derived, the lifs and sifs durations are updated as well.

2022-02-10net: mac802154: Convert the symbol duration into nanosecondsMiquel Raynal1-2/+2
Tdsym is often given in the spec as pretty small numbers in microseconds and hence was reflected in the code as symbol_duration and was stored as a u8. Actually, for UWB PHYs, the symbol duration is given in nanoseconds and are as precise as picoseconds. In order to handle better these PHYs, change the type of symbol_duration to u32 and store this value in nanoseconds. All the users of this variable are updated in a mechanical way.

2022-02-10spi: mxic: Add support for pipelined ECC operationsMiquel Raynal2-1/+16
Some SPI-NAND chips do not have a proper on-die ECC engine providing error correction/detection. This is particularly an issue on embedded devices with limited resources because all the computations must happen in software, unless an external hardware engine is provided. These external engines are new and can be of two categories: external or pipelined. Macronix is providing both, the former being already supported. The second, however, is very SoC implementation dependent and must be instantiated by the SPI host controller directly. An entire subsystem has been contributed to support these engines which makes the insertion into another subsystem such as SPI quite straightforward without the need for a lot of specific functions.

2022-02-10mtd: spinand: Create direct mapping descriptors for ECC operationsMiquel Raynal1-0/+2
In order for pipelined ECC engines to be able to enable/disable the ECC engine only when needed and avoid races when future parallel-operations will be supported, we need to provide the information about the use of the ECC engine in the direct mapping hooks. As direct mapping configurations are meant to be static, it is best to create two new mappings: one for regular 'raw' accesses and one for accesses involving correction. It is up to the driver to use or not the new ECC enable boolean contained in the spi-mem operation. As dirmaps are not free (they consume a few pages of MMIO address space) and because these extra entries are only meant to be used by pipelined engines, let's limit their use to this specific type of engine and save a bit of memory with all the other setups.

2022-02-09bpf: Make remote_port field in struct bpf_sk_lookup 16-bit wideJakub Sitnicki1-1/+2
remote_port is another case of a BPF context field documented as a 32-bit value in network byte order for which the BPF context access converter generates a load of a zero-padded 16-bit integer in network byte order. First such case was dst_port in bpf_sock which got addressed in commit 4421a582718a ("bpf: Make dst_port field in struct bpf_sock 16-bit wide"). Loading 4-bytes from the remote_port offset and converting the value with bpf_ntohl() leads to surprising results, as the expected value is shifted by 16 bits. Reduce the confusion by splitting the field in two - a 16-bit field holding a big-endian integer, and a 16-bit zero-padding anonymous field that follows it.

2022-02-09net: fix a memleak when uncloning an skb dst and its metadataAntoine Tenart1-1/+0
When uncloning an skb dst and its associated metadata, a new dst+metadata is allocated and later replaces the old one in the skb. This is helpful to have a non-shared dst+metadata attached to a specific skb. The issue is the uncloned dst+metadata is initialized with a refcount of 1, which is increased to 2 before attaching it to the skb. When tun_dst_unclone returns, the dst+metadata is only referenced from a single place (the skb) while its refcount is 2. Its refcount will never drop to 0 (when the skb is consumed), leading to a memory leak. Fix this by removing the call to dst_hold in tun_dst_unclone, as the dst+metadata refcount is already 1.

When uncloning an skb dst and its associated metadata a new dst+metadata is allocated and the tunnel information from the old metadata is copied over there. The issue is the tunnel metadata has references to cached dst, which are copied along the way. When a dst+metadata refcount drops to 0 the metadata is freed including the cached dst entries. As they are also referenced in the initial dst+metadata, this ends up in UaFs. In practice the above did not happen because of another issue, the dst+metadata was never freed because its refcount never dropped to 0 (this will be fixed in a subsequent patch). Fix this by initializing the dst cache after copying the tunnel information from the old metadata to also unshare the dst cache.

2022-02-09peci: Add device detectionIwona Winiarska1-0/+2
Since PECI devices are discoverable, we can dynamically detect devices that are actually available in the system. This change complements the earlier implementation by rescanning PECI bus to detect available devices. For this purpose, it also introduces the minimal API for PECI requests.

2022-02-09peci: Add core infrastructureIwona Winiarska1-0/+99
Intel processors provide access for various services designed to support processor and DRAM thermal management, platform manageability and processor interface tuning and diagnostics. Those services are available via the Platform Environment Control Interface (PECI) that provides a communication channel between the processor and the Baseboard Management Controller (BMC) or other platform management device. This change introduces PECI subsystem by adding the initial core module and API for controller drivers.

2022-02-08fscrypt: add functions for direct I/O supportEric Biggers1-0/+18
Encrypted files traditionally haven't supported DIO, due to the need to encrypt/decrypt the data. However, when the encryption is implemented using inline encryption (blk-crypto) instead of the traditional filesystem-layer encryption, it is straightforward to support DIO. In preparation for supporting this, add the following functions: - fscrypt_dio_supported() checks whether a DIO request is supported as far as encryption is concerned. Encrypted files will only support DIO when inline encryption is used and the I/O request is properly aligned; this function checks these preconditions. - fscrypt_limit_io_blocks() limits the length of a bio to avoid crossing a place in the file that a bio with an encryption context cannot cross due to a DUN discontiguity. This function is needed by filesystems that use the iomap DIO implementation (which operates directly on logical ranges, so it won't use fscrypt_mergeable_bio()) and that support FSCRYPT_POLICY_FLAG_IV_INO_LBLK_32.

The ARM PMU driver calls kvm_host_pmu_init() after probing to tell KVM that a hardware PMU is available for guest emulation. Heterogeneous systems can have more than one PMU present, and the callback gets called multiple times, once for each of them. Keep track of all the PMUs available to KVM, as they're going to be needed later.

Commit 0793a61d4df8 ("performance counters: core code") added the perf subsystem (then called Performance Counters) to Linux, creating the struct perf_cpu_context. The comment for the struct referred to it as a "struct perf_counter_cpu_context". Commit cdd6c482c9ff ("perf: Do the big rename: Performance Counters -> Performance Events") changed the comment to refer to a "struct perf_event_cpu_context", which was still the wrong name for the struct.
