2023-06-02crypto: ccp - Validate that platform access mailbox registers are declaredMario Limonciello
Some platforms might support platform access doorbell but not mailbox. Add an extra guard to ensure this doesn't cause accesses to wrong ranges if a consumer calls psp_send_platform_access_msg().

The "level" field in the status register contains the number of random bytes that are available in the FIFO. Use GENMASK to extract this field.

2023-05-12hwrng: virtio - Fix race on data_avail and actual dataHerbert Xu
The virtio rng device kicks off a new entropy request whenever the data available reaches zero. When a new request occurs at the end of a read operation, that is, when the result of that request is only needed by the next reader, then there is a race between the writing of the new data and the next reader. This is because there is no synchronisation whatsoever between the writer and the reader. Fix this by writing data_avail with smp_store_release and reading it with smp_load_acquire when we first enter read. The subsequent reads are safe because they're either protected by the first load acquire, or by the completion mechanism. Also remove the redundant zeroing of data_idx in random_recv_done (data_idx must already be zero at this point) and data_avail in request_entropy (ditto).

2023-05-12crypto: octeontx2 - hardware configuration for inline IPsecSrujana Challa
On OcteonTX2/OctoenTX3 variants of silicon, Admin function (AF) handles resource allocation and configuration for PFs and their VFs. PFs request the AF directly, via mailboxes. Unlike PFs, VFs cannot send a mailbox request directly. A VF sends mailbox messages to its parent PF, with which it shares a mailbox region. The PF then forwards these messages to the AF. This patch adds code to configure inline-IPsec HW resources for CPT VFs as CPT VFs cannot send a mailbox request directly to AF.

2023-05-05net: fec: correct the counting of XDP sent framesShenwei Wang
In the current xdp_xmit implementation, if any single frame fails to transmit due to insufficient buffer descriptors, the function nevertheless reports success in sending all frames. This results in erroneously indicating that frames were transmitted when in fact they were dropped. This patch fixes the issue by ensureing the return value properly indicates the actual number of frames successfully transmitted, rather than potentially reporting success for all frames when some could not transmit.

2023-05-05net: dsa: mt7530: fix network connectivity with multiple CPU portsArınç ÜNAL
On mt753x_cpu_port_enable() there's code that enables flooding for the CPU port only. Since mt753x_cpu_port_enable() runs twice when both CPU ports are enabled, port 6 becomes the only port to forward the frames to. But port 5 is the active port, so no frames received from the user ports will be forwarded to port 5 which breaks network connectivity. Every bit of the BC_FFP, UNM_FFP, and UNU_FFP bits represents a port. Fix this issue by setting the bit that corresponds to the CPU port without overwriting the other bits. Clear the bits beforehand only for the MT7531 switch. According to the documents MT7621 Giga Switch Programming Guide v0.3 and MT7531 Reference Manual for Development Board v1.0, after reset, the BC_FFP, UNM_FFP, and UNU_FFP bits are set to 1 for MT7531, 0 for MT7530. The commit 5e5502e012b8 ("net: dsa: mt7530: fix roaming from DSA user ports") silently changed the method to set the bits on the MT7530_MFC. Instead of clearing the relevant bits before mt7530_cpu_port_enable() which runs under a for loop, the commit started doing it on mt7530_cpu_port_enable(). Back then, this didn't really matter as only a single CPU port could be used since the CPU port number was hardcoded. The driver was later changed with commit 1f9a6abecf53 ("net: dsa: mt7530: get cpu-port via dp->cpu_dp instead of constant") to retrieve the CPU port via dp->cpu_dp. With that, this silent change became an issue for when using multiple CPU ports.

2023-05-05net: dsa: mt7530: fix corrupt frames using trgmii on 40 MHz XTAL MT7621Arınç ÜNAL
The multi-chip module MT7530 switch with a 40 MHz oscillator on the MT7621AT, MT7621DAT, and MT7621ST SoCs forwards corrupt frames using trgmii. This is caused by the assumption that MT7621 SoCs have got 150 MHz PLL, hence using the ncpo1 value, 0x0780. My testing shows this value works on Unielec U7621-06, Bartel's testing shows it won't work on Hi-Link HLK-MT7621A and Netgear WAC104. All devices tested have got 40 MHz oscillators. Using the value for 125 MHz PLL, 0x0640, works on all boards at hand. The definitions for 125 MHz PLL exist on the Banana Pi BPI-R2 BSP source code whilst 150 MHz PLL don't. Forwarding frames using trgmii on the MCM MT7530 switch with a 25 MHz oscillator on the said MT7621 SoCs works fine because the ncpo1 value defined for it is for 125 MHz PLL. Change the 150 MHz PLL comment to 125 MHz PLL, and use the 125 MHz PLL ncpo1 values for both oscillator frequencies.

2023-05-04thermal: intel: powerclamp: Fix NULL pointer access issueSrinivas Pandruvada
If cur_state for the powerclamp cooling device is set to the default minimum state of 0, without setting first to cur_state > 0, this results in NULL pointer access. This NULL pointer access happens in the powercap core idle-inject function idle_inject_set_duration() as there is no NULL check for idle_inject_device pointer. This pointer must be allocated by calling idle_inject_register() or idle_inject_register_full(). In the function powerclamp_set_cur_state(), idle_inject_device pointer is allocated only when the cur_state > 0. But setting 0 without changing to any other state, idle_inject_set_duration() will be called with a NULL idle_inject_device pointer. To address this, just return from powerclamp_set_cur_state() if the current cooling device state is the same as the last one. Since the power-up default cooling device state is 0, changing the state to 0 again here will return without calling idle_inject_set_duration().
