2023-06-21tty_audit: invert the condition in tty_audit_log()Jiri Slaby
If we cannot obtain an audit buffer in tty_audit_log(), simply return from the function. Apart this is mostly preferred in the kernel, it allows to merge the split audit string while still keeping it readable.

2023-06-21Revert "8250: add support for ASIX devices with a FIFO bug"Jiaqing Zhao
This reverts commit eb26dfe8aa7eeb5a5aa0b7574550125f8aa4c3b3. Commit eb26dfe8aa7e ("8250: add support for ASIX devices with a FIFO bug") merged on Jul 13, 2012 adds a quirk for PCI_VENDOR_ID_ASIX (0x9710). But that ID is the same as PCI_VENDOR_ID_NETMOS defined in 1f8b061050c7 ("[PATCH] Netmos parallel/serial/combo support") merged on Mar 28, 2005. In pci_serial_quirks array, the NetMos entry always takes precedence over the ASIX entry even since it was initially merged, code in that commit is always unreachable. In my tests, adding the FIFO workaround to pci_netmos_init() makes no difference, and the vendor driver also does not have such workaround. Given that the code was never used for over a decade, it's safe to revert it. Also, the real PCI_VENDOR_ID_ASIX should be 0x125b, which is used on their newer AX99100 PCIe serial controllers released on 2016. The FIFO workaround should not be intended for these newer controllers, and it was never implemented in vendor driver.

2023-06-21serial: atmel: don't enable IRQs prematurelyDan Carpenter
The atmel_complete_tx_dma() function disables IRQs at the start of the function by calling spin_lock_irqsave(&port->lock, flags); There is no need to disable them a second time using the spin_lock_irq() function and, in fact, doing so is a bug because it will enable IRQs prematurely when we call spin_unlock_irq(). Just use spin_lock/unlock() instead without disabling or enabling IRQs.

2023-06-21HID: hidraw: fix data race on device refcountLudvig Michaelsson
The hidraw_open() function increments the hidraw device reference counter. The counter has no dedicated synchronization mechanism, resulting in a potential data race when concurrently opening a device. The race is a regression introduced by commit 8590222e4b02 ("HID: hidraw: Replace hidraw device table mutex with a rwsem"). While minors_rwsem is intended to protect the hidraw_table itself, by instead acquiring the lock for writing, the reference counter is also protected. This is symmetrical to hidraw_release().

2023-06-21net: micrel: Change to receive timestamp in the frame for lan8841Horatiu Vultur
Currently for each timestamp frame, the SW needs to go and read the received timestamp over the MDIO bus. But the HW has the capability to store the received nanoseconds part and the least significant two bits of the seconds in the reserved field of the PTP header. In this way we could save few MDIO transactions (actually a little more transactions because the access to the PTP registers are indirect) for each received frame. Instead of reading the rest of seconds part of the timestamp of the frame using MDIO transactions schedule PTP worker thread to read the seconds part every 500ms and then for each of the received frames use this information. Because if for example running with 512 frames per second, there is no point to read 512 times the second part. Doing all these changes will give a great CPU usage performance. Running ptp4l with logSyncInterval of -9 will give a ~60% CPU improvement.

2023-06-21clk: ralink: add clock and reset driver for MTMIPS SoCsSergio Paracuellos
Until now, clock related code for old ralink SoCs was based in fixed clocks using 'clk_register_fixed_rate' and 'clkdev_create' directly doing in code and not using device tree at all for their definition. Including this driver is an effort to be able to define proper clocks using device tree and also cleaning all the clock and reset related code from 'arch/mips/ralink' dir. This clock and reset driver covers all the ralink SoCs but MT7621 which is the newest and provides gating and some differences that make it different from its predecesors. It has its own driver since some time ago. The ralink SoCs we are taking about are RT2880, RT3050, RT3052, RT3350, RT3352, RT3883, RT5350, MT7620, MT7628 and MT7688. Mostly the code in this new driver has been extracted from 'arch/mips/ralink' and cleanly put using kernel clock driver APIs. The clock plans for this SoCs only talks about relation between CPU frequency and BUS frequency. This relation is different depending on the particular SoC. CPU clock is derived from XTAL frequencies. Depending on the SoC we have the following frequencies: * RT2880 SoC: - XTAL: 40 MHz. - CPU: 250, 266, 280 or 300 MHz. - BUS: CPU / 2 MHz. * RT3050, RT3052, RT3350: - XTAL: 40 MHz. - CPU: 320 or 384 MHz. - BUS: CPU / 3 MHz. * RT3352: - XTAL: 40 MHz. - CPU: 384 or 400 MHz. - BUS: CPU / 3 MHz. - PERIPH: 40 MHz. * RT3383: - XTAL: 40 MHz. - CPU: 250, 384, 480 or 500 MHz. - BUS: Depends on RAM Type and CPU: + RAM DDR2: 125. ELSE 83 MHz. + RAM DDR2: 128. ELSE 96 MHz. + RAM DDR2: 160. ELSE 120 MHz. + RAM DDR2: 166. ELSE 125 MHz. * RT5350: - XTAL: 40 MHz. - CPU: 300, 320 or 360 MHz. - BUS: CPU / 3, CPU / 4, CPU / 3 MHz. - PERIPH: 40 MHz. * MT7628 and MT7688: - XTAL: 20 MHz or 40 MHz. - CPU: 575 or 580 MHz. - BUS: CPU / 3. - PCMI2S: 480 MHz. - PERIPH: 40 MHz. * MT7620: - XTAL: 20 MHz or 40 MHz. - PLL: XTAL, 480, 600 MHz. - CPU: depends on PLL and some mult and dividers. - BUS: depends on PLL and some mult and dividers. - PERIPH: 40 or XTAL MHz. MT7620 is a bit more complex deriving CPU clock from a PLL and an bunch of register reads and predividers. To derive CPU and BUS frequencies in the MT7620 SoC 'mt7620_calc_rate()' helper is used. In the case XTAL can have different frequencies and we need a different clock frequency for peripherals 'periph' clock in introduced. The rest of the peripherals present in the SoC just follow their parent frequencies. With this information the clk driver will provide all the clock and reset functionality from a set of hardcoded clocks allowing to define a nice device tree without fixed clocks.

As part of the new security API in the FW, all security keys are to be removed before station removal. Until now IGTK rekey wasn't supported in the D3 resume flow, and thus the driver might not know the right key to remove. If an IGTK was rekeyed during D3 the old IGTK is removed and the new key is updated. If not, the old key's IPN is updated.

2023-06-21wifi: iwlwifi: mvm: check only affected linksJohannes Berg
When hostapd starts up, it may start up with only one link while the other is still scanning for overlapping BSSes. A station might start to connect at this point, but we run into this warning instead. Since there's no need to check for _all_ links, restrict the check to just the affected links that the STA will be using.

2023-06-21wifi: iwlwifi: mvm: avoid baid size integer overflowJohannes Berg
Roee reported various hard-to-debug crashes with pings in EHT aggregation scenarios. Enabling KASAN showed that we access the BAID allocation out of bounds, and looking at the code a bit shows that since the reorder buffer entry (struct iwl_mvm_reorder_buf_entry) is 128 bytes if debug such as lockdep is enabled, then staring from an agg size 512 we overflow the size calculation, and allocate a much smaller structure than we should, causing slab corruption once we initialize this. Fix this by simply using u32 instead of u16.
