2022-02-04dt-bindings: remoteproc: ti: Add mailbox provider nodes to exampleRob Herring2-0/+16
In order to make the 'mboxes' property in the TI remoteproc examples parseable, mailbox provider nodes are needed. Normally, the examples have a __fixup__ node which can be used for determining each phandle+arg entry. However, for this binding the arg cells contain a phandle, and the __fixups__ information can't be used.

2022-02-04dt-bindings: ingenic,i2c: Rework interrupts in exampleRob Herring1-3/+1

2022-02-04dt-bindings: Improve phandle-array schemasRob Herring67-119/+318
The 'phandle-array' type is a bit ambiguous. It can be either just an array of phandles or an array of phandles plus args. Many schemas for phandle-array properties aren't clear in the schema which case applies though the description usually describes it. The array of phandles case boils down to needing: items: maxItems: 1 The phandle plus args cases should typically take this form: items: - items: - description: A phandle - description: 1st arg cell - description: 2nd arg cell With this change, some examples need updating so that the bracketing of property values matches the schema.

2022-02-04cfg80211: fix race in netlink owner interface destructionJohannes Berg1-13/+4
My previous fix here to fix the deadlock left a race where the exact same deadlock (see the original commit referenced below) can still happen if cfg80211_destroy_ifaces() already runs while nl80211_netlink_notify() is still marking some interfaces as nl_owner_dead. The race happens because we have two loops here - first we dev_close() all the netdevs, and then we destroy them. If we also have two netdevs (first one need only be a wdev though) then we can find one during the first iteration, close it, and go to the second iteration -- but then find two, and try to destroy also the one we didn't close yet. Fix this by only iterating once.

2022-02-04eeprom: ee1004: limit i2c reads to I2C_SMBUS_BLOCK_MAXJonas Malaco1-0/+3
Commit effa453168a7 ("i2c: i801: Don't silently correct invalid transfer size") revealed that ee1004_eeprom_read() did not properly limit how many bytes to read at once. In particular, i2c_smbus_read_i2c_block_data_or_emulated() takes the length to read as an u8. If count == 256 after taking into account the offset and page boundary, the cast to u8 overflows. And this is common when user space tries to read the entire EEPROM at once. To fix it, limit each read to I2C_SMBUS_BLOCK_MAX (32) bytes, already the maximum length i2c_smbus_read_i2c_block_data_or_emulated() allows.

2022-02-04cfg80211/mac80211: assume CHECKSUM_COMPLETE includes SNAPJohannes Berg3-3/+10
There's currently only one driver that reports CHECKSUM_COMPLETE, that is iwlwifi. The current hardware there calculates checksum after the SNAP header, but only RFC 1042 (and some other cases, but replicating the exact hardware logic for corner cases in the driver seemed awkward.) Newer generations of hardware will checksum _including_ the SNAP, which makes things easier. To handle that, simply always assume the checksum _includes_ the SNAP header, which this patch does, requiring to first add it for older iwlwifi hardware, and then remove it again later on conversion. Alternatively, we could have: 1) Always assumed the checksum starts _after_ the SNAP header; the problem with this is that we'd have to replace the exact "what is the SNAP" check in iwlwifi that cfg80211 has. 2) Made it configurable with some flag, but that seemed like too much complexity.

2022-02-04serial: core: Fix the definition name in the comment of UPF_* flagsAndy Shevchenko1-1/+1
From day 1 the UPF_LAST_USER wasn't defined, a specific number of the last bit for userspace. Instead the code always relies on ASYNCB_LAST_USER. Fix comment accordingly.

2022-02-04block: initialize the target bio in __bio_clone_fastChristoph Hellwig3-37/+40

2022-02-04dm: use bio_clone_fast in alloc_io/alloc_tioChristoph Hellwig1-9/+3
Replace open coded bio_clone_fast implementations with the actual helper. Note that the bio allocated as part of the dm_io structure in alloc_io will only actually be used later in alloc_tio, making this earlier cloning of the information safe.

2022-02-04block: clone crypto and integrity data in __bio_clone_fastChristoph Hellwig7-45/+22
__bio_clone_fast should also clone integrity and crypto data, as a clone without those is incomplete. Right now the only caller that can actually support crypto and integrity data (dm) does it manually for the one callchain that supports these, but we better do it properly in the core. Note that all callers except for the above mentioned one also don't need to handle failure at all, given that the integrity and crypto clones are based on mempool allocations that won't fail for sleeping allocations.
