2022-06-30serial: 8250: fix return error code in serial8250_request_std_resource()Yi Yang
If port->mapbase = NULL in serial8250_request_std_resource() , it need return a error code instead of 0. If uart_set_info() fail to request new regions by serial8250_request_std_resource() but the return value of serial8250_request_std_resource() is 0, The system incorrectly considers that the resource application is successful and does not attempt to restore the old setting. A null pointer reference is triggered when the port resource is later invoked.

2022-06-30serial: stm32: Clear prev values before setting RTS delaysIlpo Järvinen
The code lacks clearing of previous DEAT/DEDT values. Thus, changing values on the fly results in garbage delays tending towards the maximum value as more and more bits are ORed together.

sfp_probe() allocates a memory chunk from sfp with sfp_alloc(). When devm_add_action() fails, sfp is not freed, which leads to a memory leak. We should use devm_add_action_or_reset() instead of devm_add_action().

2022-06-30mlxsw: spectrum_router: Fix rollback in tunnel next hop initPetr Machata
In mlxsw_sp_nexthop6_init(), a next hop is always added to the router linked list, and mlxsw_sp_nexthop_type_init() is invoked afterwards. When that function results in an error, the next hop will not have been removed from the linked list. As the error is propagated upwards and the caller frees the next hop object, the linked list ends up holding an invalid object. A similar issue comes up with mlxsw_sp_nexthop4_init(), where rollback block does exist, however does not include the linked list removal. Both IPv6 and IPv4 next hops have a similar issue with next-hop counter rollbacks. As these were introduced in the same patchset as the next hop linked list, include the cleanup in this patch.

2022-06-30net: usb: ax88179_178a: Fix packet receivingJose Alonso
This patch corrects packet receiving in ax88179_rx_fixup. - problem observed: ifconfig shows allways a lot of 'RX Errors' while packets are received normally. This occurs because ax88179_rx_fixup does not recognise properly the usb urb received. The packets are normally processed and at the end, the code exits with 'return 0', generating RX Errors. (pkt_cnt==-2 and ptk_hdr over field rx_hdr trying to identify another packet there) This is a usb urb received by "tcpdump -i usbmon2 -X" on a little-endian CPU: 0x0000: eeee f8e3 3b19 87a0 94de 80e3 daac 0800 ^ packet 1 start (pkt_len = 0x05ec) ^^^^ IP alignment pseudo header ^ ethernet packet start last byte ethernet packet v padding (8-bytes aligned) vvvv vvvv 0x05e0: c92d d444 1420 8a69 83dd 272f e82b 9811 0x05f0: eeee f8e3 3b19 87a0 94de 80e3 daac 0800 ... ^ packet 2 0x0be0: eeee f8e3 3b19 87a0 94de 80e3 daac 0800 ... 0x1130: 9d41 9171 8a38 0ec5 eeee f8e3 3b19 87a0 ... 0x1720: 8cfc 15ff 5e4c e85c eeee f8e3 3b19 87a0 ... 0x1d10: ecfa 2a3a 19ab c78c eeee f8e3 3b19 87a0 ... 0x2070: eeee f8e3 3b19 87a0 94de 80e3 daac 0800 ... ^ packet 7 0x2120: 7c88 4ca5 5c57 7dcc 0d34 7577 f778 7e0a 0x2130: f032 e093 7489 0740 3008 ec05 0000 0080 ====1==== ====2==== hdr_off ^ pkt_len = 0x05ec ^^^^ AX_RXHDR_*=0x00830 ^^^^ ^ pkt_len = 0 ^^^^ AX_RXHDR_DROP_ERR=0x80000000 ^^^^ ^ 0x2140: 3008 ec05 0000 0080 3008 5805 0000 0080 0x2150: 3008 ec05 0000 0080 3008 ec05 0000 0080 0x2160: 3008 5803 0000 0080 3008 c800 0000 0080 ===11==== ===12==== ===13==== ===14==== 0x2170: 0000 0000 0e00 3821 ^^^^ ^^^^ rx_hdr ^^^^ pkt_cnt=14 ^^^^ hdr_off=0x2138 ^^^^ ^^^^ padding The dump shows that pkt_cnt is the number of entrys in the per-packet metadata. It is "2 * packet count". Each packet have two entrys. The first have a valid value (pkt_len and AX_RXHDR_*) and the second have a dummy-header 0x80000000 (pkt_len=0 with AX_RXHDR_DROP_ERR). Why exists dummy-header for each packet?!? My guess is that this was done probably to align the entry for each packet to 64-bits and maintain compatibility with old firmware. There is also a padding (0x00000000) before the rx_hdr to align the end of rx_hdr to 64-bit. Note that packets have a alignment of 64-bits (8-bytes). This patch assumes that the dummy-header and the last padding are optional. So it preserves semantics and recognises the same valid packets as the current code.

2022-06-29net: bonding: fix use-after-free after 802.3ad slave unbindYevhen Orlov
commit 0622cab0341c ("bonding: fix 802.3ad aggregator reselection"), resolve case, when there is several aggregation groups in the same bond. bond_3ad_unbind_slave will invalidate (clear) aggregator when __agg_active_ports return zero. So, ad_clear_agg can be executed even, when num_of_ports!=0. Than bond_3ad_unbind_slave can be executed again for, previously cleared aggregator. NOTE: at this time bond_3ad_unbind_slave will not update slave ports list, because lag_ports==NULL. So, here we got slave ports, pointing to freed aggregator memory. Fix with checking actual number of ports in group (as was before commit 0622cab0341c ("bonding: fix 802.3ad aggregator reselection") ), before ad_clear_agg().

2022-06-29net: phy: Don't trigger state machine while in suspendLukas Wunner
Upon system sleep, mdio_bus_phy_suspend() stops the phy_state_machine(), but subsequent interrupts may retrigger it: They may have been left enabled to facilitate wakeup and are not quiesced until the ->suspend_noirq() phase. Unwanted interrupts may hence occur between mdio_bus_phy_suspend() and dpm_suspend_noirq(), as well as between dpm_resume_noirq() and mdio_bus_phy_resume(). Retriggering the phy_state_machine() through an interrupt is not only undesirable for the reason given in mdio_bus_phy_suspend() (freezing it midway with phydev->lock held), but also because the PHY may be inaccessible after it's suspended: Accesses to USB-attached PHYs are blocked once usb_suspend_both() clears the can_submit flag and PHYs on PCI network cards may become inaccessible upon suspend as well. Amend phy_interrupt() to avoid triggering the state machine if the PHY is suspended. Signal wakeup instead if the attached net_device or its parent has been configured as a wakeup source. (Those conditions are identical to mdio_bus_phy_may_suspend().) Postpone handling of the interrupt until the PHY has resumed. Before stopping the phy_state_machine() in mdio_bus_phy_suspend(), wait for a concurrent phy_interrupt() to run to completion. That is necessary because phy_interrupt() may have checked the PHY's suspend status before the system sleep transition commenced and it may thus retrigger the state machine after it was stopped. Likewise, after re-enabling interrupt handling in mdio_bus_phy_resume(), wait for a concurrent phy_interrupt() to complete to ensure that interrupts which it postponed are properly rerun. The issue was exposed by commit 1ce8b37241ed ("usbnet: smsc95xx: Forward PHY interrupts to PHY driver to avoid polling"), but has existed since forever.

2022-06-30PM / devfreq: Rework freq_table to be local to devfreq structChristian Marangi
On a devfreq PROBE_DEFER, the freq_table in the driver profile struct, is never reset and may be leaved in an undefined state. This comes from the fact that we store the freq_table in the driver profile struct that is commonly defined as static and not reset on PROBE_DEFER. We currently skip the reinit of the freq_table if we found it's already defined since a driver may declare his own freq_table. This logic is flawed in the case devfreq core generate a freq_table, set it in the profile struct and then PROBE_DEFER, freeing the freq_table. In this case devfreq will found a NOT NULL freq_table that has been freed, skip the freq_table generation and probe the driver based on the wrong table. To fix this and correctly handle PROBE_DEFER, use a local freq_table and max_state in the devfreq struct and never modify the freq_table present in the profile struct if it does provide it.

2022-06-29i2c: piix4: Fix a memory leak in the EFCH MMIO supportJean Delvare
The recently added support for EFCH MMIO regions introduced a memory leak in that code path. The leak is caused by the fact that release_resource() merely removes the resource from the tree but does not free its memory. We need to call release_mem_region() instead, which does free the memory. As a nice side effect, this brings back some symmetry between the legacy and MMIO paths.

2022-06-29usb: dwc3: gadget: Fix event pending checkThinh Nguyen
The DWC3_EVENT_PENDING flag is used to protect against invalid call to top-half interrupt handler, which can occur when there's a delay in software detection of the interrupt line deassertion. However, the clearing of this flag was done prior to unmasking the interrupt line, creating opportunity where the top-half handler can come. This breaks the serialization and creates a race between the top-half and bottom-half handler, resulting in losing synchronization between the controller and the driver when processing events. To fix this, make sure the clearing of the DWC3_EVENT_PENDING is done at the end of the bottom-half handler.

2022-06-29fbdev: Disable sysfb device registration when removing conflicting FBsJavier Martinez Canillas
The platform devices registered by sysfb match with firmware-based DRM or fbdev drivers, that are used to have early graphics using a framebuffer provided by the system firmware. DRM or fbdev drivers later are probed and remove conflicting framebuffers, leading to these platform devices for generic drivers to be unregistered. But the current solution has a race, since the sysfb_init() function could be called after a DRM or fbdev driver is probed and request to unregister the devices for drivers with conflicting framebuffes. To prevent this, disable any future sysfb platform device registration by calling sysfb_disable(), if a driver requests to remove the conflicting framebuffers.
