2021-12-03serial: 8250_bcm7271: UART errors after resuming from S2Al Cooper
There is a small window in time during resume where the hardware flow control signal RTS can be asserted (which allows a sender to resume sending data to the UART) but the baud rate has not yet been restored. This will cause corrupted data and FRAMING, OVERRUN and BREAK errors. This is happening because the MCTRL register is shadowed in uart_port struct and is later used during resume to set the MCTRL register during both serial8250_do_startup() and uart_resume_port(). Unfortunately, serial8250_do_startup() happens before the UART baud rate is restored. The fix is to clear the shadowed mctrl value at the end of suspend and restore it at the end of resume.

2021-12-03usb: cdnsp: Fix a NULL pointer dereference in cdnsp_endpoint_init()Zhou Qingyang
In cdnsp_endpoint_init(), cdnsp_ring_alloc() is assigned to pep->ring and there is a dereference of it in cdnsp_endpoint_init(), which could lead to a NULL pointer dereference on failure of cdnsp_ring_alloc(). Fix this bug by adding a check of pep->ring. This bug was found by a static analyzer. The analysis employs differential checking to identify inconsistent security operations (e.g., checks or kfrees) between two code paths and confirms that the inconsistent operations are not recovered in the current function or the callers, so they constitute bugs. Note that, as a bug found by static analysis, it can be a false positive or hard to trigger. Multiple researchers have cross-reviewed the bug. Builds with CONFIG_USB_CDNSP_GADGET=y show no new warnings, and our static analyzer no longer warns about this code.

2021-12-03usb: typec: tcpm: Wait in SNK_DEBOUNCED until disconnectBadhri Jagan Sridharan
Stub from the spec: "4.5.2.2.4.2 Exiting from AttachWait.SNK State A Sink shall transition to Unattached.SNK when the state of both the CC1 and CC2 pins is SNK.Open for at least tPDDebounce. A DRP shall transition to Unattached.SRC when the state of both the CC1 and CC2 pins is SNK.Open for at least tPDDebounce." This change makes TCPM to wait in SNK_DEBOUNCED state until CC1 and CC2 pins is SNK.Open for at least tPDDebounce. Previously, TCPM resets the port if vbus is not present in PD_T_PS_SOURCE_ON. This causes TCPM to loop continuously when connected to a faulty power source that does not present vbus. Waiting in SNK_DEBOUNCED also ensures that TCPM is adherant to "4.5.2.2.4.2 Exiting from AttachWait.SNK State" requirements.

2021-12-03xhci: Fix commad ring abort, write all 64 bits to CRCR register.Mathias Nyman
Turns out some xHC controllers require all 64 bits in the CRCR register to be written to execute a command abort. The lower 32 bits containing the command abort bit is written first. In case the command ring stops before we write the upper 32 bits then hardware may use these upper bits to set the commnd ring dequeue pointer. Solve this by making sure the upper 32 bits contain a valid command ring dequeue pointer. The original patch that only wrote the first 32 to stop the ring went to stable, so this fix should go there as well.

2021-12-02ethernet: aquantia: Try MAC address from device treeTianhao Chai
Apple M1 Mac minis (2020) with 10GE NICs do not have MAC address in the card, but instead need to obtain MAC addresses from the device tree. In this case the hardware will report an invalid MAC. Currently atlantic driver does not query the DT for MAC address and will randomly assign a MAC if the NIC doesn't have a permanent MAC burnt in. This patch causes the driver to perfer a valid MAC address from OF (if present) over HW self-reported MAC and only fall back to a random MAC address when neither of them is valid.

2021-12-01octeontx2-af: Fix a memleak bug in rvu_mbox_init()Zhou Qingyang
In rvu_mbox_init(), mbox_regions is not freed or passed out under the switch-default region, which could lead to a memory leak. Fix this bug by changing 'return err' to 'goto free_regions'. This bug was found by a static analyzer. The analysis employs differential checking to identify inconsistent security operations (e.g., checks or kfrees) between two code paths and confirms that the inconsistent operations are not recovered in the current function or the callers, so they constitute bugs. Note that, as a bug found by static analysis, it can be a false positive or hard to trigger. Multiple researchers have cross-reviewed the bug. Builds with CONFIG_OCTEONTX2_AF=y show no new warnings, and our static analyzer no longer warns about this code.

IPCB/IP6CB need to be initialized when processing outbound v4 or v6 pkts in the codepath of vrf device xmit function so that leftover garbage doesn't cause futher code that uses the CB to incorrectly process the pkt.

2021-12-01powercap/drivers/dtpm: Disable DTPM at boot timeDaniel Lezcano
The DTPM framework misses a mechanism to set it up. That is currently under review but will come after the next cycle. As the distro are enabling all the kernel options, the DTPM framework is enabled on platforms where the energy model is not implemented, thus making the framework inconsistent and disrupting the CPU frequency scaling service. Remove the initialization at boot time as a hot fix.
