2022-08-26Merge tag 'arm64-fixes' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux Pull arm64 fixes from Will Deacon: "A bumper crop of arm64 fixes for -rc3. The largest change is fixing our parsing of the 'rodata=full' command line option, which kstrtobool() started treating as 'rodata=false'. The fix actually makes the parsing of that option much less fragile and updates the documentation at the same time. We still have a boot issue pending when KASLR is disabled at compile time, but there's a fresh fix on the list which I'll send next week if it holds up to testing. Summary: - Fix workaround for Cortex-A76 erratum #1286807 - Add workaround for AMU erratum #2457168 on Cortex-A510 - Drop reference to removed CONFIG_ARCH_RANDOM #define - Fix parsing of the "rodata=full" cmdline option - Fix a bunch of issues in the SME register state switching and sigframe code - Fix incorrect extraction of the CTR_EL0.CWG register field - Fix ACPI cache topology probing when the PPTT is not present - Trivial comment and whitespace fixes" * tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux: arm64/sme: Don't flush SVE register state when handling SME traps arm64/sme: Don't flush SVE register state when allocating SME storage arm64/signal: Flush FPSIMD register state when disabling streaming mode arm64/signal: Raise limit on stack frames arm64/cache: Fix cache_type_cwg() for register generation arm64/sysreg: Guard SYS_FIELD_ macros for asm arm64/sysreg: Directly include bitfield.h arm64: cacheinfo: Fix incorrect assignment of signed error value to unsigned fw_level arm64: errata: add detection for AMEVCNTR01 incrementing incorrectly arm64: fix rodata=full arm64: Fix comment typo docs/arm64: elf_hwcaps: unify newlines in HWCAP lists arm64: adjust KASLR relocation after ARCH_RANDOM removal arm64: Fix match_list for erratum 1286807 on Arm Cortex-A76

2022-08-26wait_on_bit: add an acquire memory barrierMikulas Patocka
There are several places in the kernel where wait_on_bit is not followed by a memory barrier (for example, in drivers/md/dm-bufio.c:new_read). On architectures with weak memory ordering, it may happen that memory accesses that follow wait_on_bit are reordered before wait_on_bit and they may return invalid data. Fix this class of bugs by introducing a new function "test_bit_acquire" that works like test_bit, but has acquire memory ordering semantics.

When the xrx200_hw_receive() function returns -ENOMEM, the NAPI poll function immediately returns an error. This is incorrect for two reasons: * the function terminates without enabling interrupts or scheduling NAPI, * the error code (-ENOMEM) is returned instead of the number of received packets. After the first memory allocation failure occurs, packet reception is locked due to disabled interrupts from DMA..

2022-08-25net: stmmac: work around sporadic tx issue on link-upHeiner Kallweit
This is a follow-up to the discussion in [0]. It seems to me that at least the IP version used on Amlogic SoC's sometimes has a problem if register MAC_CTRL_REG is written whilst the chip is still processing a previous write. But that's just a guess. Adding a delay between two writes to this register helps, but we can also simply omit the offending second write. This patch uses the second approach and is based on a suggestion from Qi Duan. Benefit of this approach is that we can save few register writes, also on not affected chip versions.

In looping on FW update tests we occasionally see the FW_ACTIVATE_STATUS command fail while it is in its EAGAIN loop waiting for the FW activate step to finsh inside the FW. The firmware is complaining that the done bit is set when a new dev_cmd is going to be processed. Doing a clean on the cmd registers and doorbell before exiting the wait-for-done and cleaning the done bit before the sleep prevents this from occurring.

2022-08-25ionic: clear broken state on generation changeShannon Nelson
There is a case found in heavy testing where a link flap happens just before a firmware Recovery event and the driver gets stuck in the BROKEN state. This comes from the driver getting interrupted by a FW generation change when coming back up from the link flap, and the call to ionic_start_queues() in ionic_link_status_check() fails. This can be addressed by having the fw_up code clear the BROKEN bit if seen, rather than waiting for a user to manually force the interface down and then back up.

2022-08-25rxrpc: Fix locking in rxrpc's sendmsgDavid Howells
Fix three bugs in the rxrpc's sendmsg implementation: (1) rxrpc_new_client_call() should release the socket lock when returning an error from rxrpc_get_call_slot(). (2) rxrpc_wait_for_tx_window_intr() will return without the call mutex held in the event that we're interrupted by a signal whilst waiting for tx space on the socket or relocking the call mutex afterwards. Fix this by: (a) moving the unlock/lock of the call mutex up to rxrpc_send_data() such that the lock is not held around all of rxrpc_wait_for_tx_window*() and (b) indicating to higher callers whether we're return with the lock dropped. Note that this means recvmsg() will not block on this call whilst we're waiting. (3) After dropping and regaining the call mutex, rxrpc_send_data() needs to go and recheck the state of the tx_pending buffer and the tx_total_len check in case we raced with another sendmsg() on the same call. Thinking on this some more, it might make sense to have different locks for sendmsg() and recvmsg(). There's probably no need to make recvmsg() wait for sendmsg(). It does mean that recvmsg() can return MSG_EOR indicating that a call is dead before a sendmsg() to that call returns - but that can currently happen anyway. Without fix (2), something like the following can be induced: WARNING: bad unlock balance detected! 5.16.0-rc6-syzkaller #0 Not tainted ------------------------------------- syz-executor011/3597 is trying to release lock (&call->user_mutex) at: [<ffffffff885163a3>] rxrpc_do_sendmsg+0xc13/0x1350 net/rxrpc/sendmsg.c:748 but there are no more locks to release! other info that might help us debug this: no locks held by syz-executor011/3597. ...

2022-08-25LoongArch: Add subword xchg/cmpxchg emulationHuacai Chen
LoongArch only support 32-bit/64-bit xchg/cmpxchg in native. But percpu operation, qspinlock and some drivers need 8-bit/16-bit xchg/cmpxchg. We add subword xchg/cmpxchg emulation in this patch because the emulation has better performance than the generic implementation (on NUMA system), and it can fix some build errors meanwhile [1]. LoongArch's guarantee for forward progress (avoid many ll/sc happening at the same time and no one succeeds): We have the "exclusive access (with timeout) of ll" feature to avoid simultaneous ll (which also blocks other memory load/store on the same address), and the "random delay of sc" feature to avoid simultaneous sc. It is a mandatory requirement for multi-core LoongArch processors to implement such features, only except those single-core and dual-core processors (they also don't support multi-chip interconnection). Feature bits are introduced in CPUCFG3, bit 3 and bit 4 [2].

2022-08-24ixgbe: stop resetting SYSTIME in ixgbe_ptp_start_cyclecounterJacob Keller
The ixgbe_ptp_start_cyclecounter is intended to be called whenever the cyclecounter parameters need to be changed. Since commit a9763f3cb54c ("ixgbe: Update PTP to support X550EM_x devices"), this function has cleared the SYSTIME registers and reset the TSAUXC DISABLE_SYSTIME bit. While these need to be cleared during ixgbe_ptp_reset, it is wrong to clear them during ixgbe_ptp_start_cyclecounter. This function may be called during both reset and link status change. When link changes, the SYSTIME counter is still operating normally, but the cyclecounter should be updated to account for the possibly changed parameters. Clearing SYSTIME when link changes causes the timecounter to jump because the cycle counter now reads zero. Extract the SYSTIME initialization out to a new function and call this during ixgbe_ptp_reset. This prevents the timecounter adjustment and avoids an unnecessary reset of the current time. This also restores the original SYSTIME clearing that occurred during ixgbe_ptp_reset before the commit above.
