I wrote patches as well for arm32 and risc-v. But still patches are needed on xtensa, powerpc, arc, and mips. So that's 7 platforms where things aren't quite right. This sort of points to larger issues that might need a larger solution. Instead, this commit just defers setting the static branch until later in the boot process. random_init() is called after jump_label_init() has been called, and so is always a safe place from which to adjust the static branch.

Rather than accounting in bytes and multiplying (shifting), we can just account in bits and avoid the shift. The main motivation for this is there are other patches in flux that expand this code a bit, and avoiding the duplication of "* 8" everywhere makes things a bit clearer.

2022-06-10usb: gadget: u_ether: fix regression in setting fixed MAC addressMarian Postevca
In systemd systems setting a fixed MAC address through the "dev_addr" module argument fails systematically. When checking the MAC address after the interface is created it always has the same but different MAC address to the one supplied as argument. This is partially caused by systemd which by default will set an internally generated permanent MAC address for interfaces that are marked as having a randomly generated address. Commit 890d5b40908bfd1a ("usb: gadget: u_ether: fix race in setting MAC address in setup phase") didn't take into account the fact that the interface must be marked as having a set MAC address when it's set as module argument. Fixed by marking the interface with NET_ADDR_SET when the "dev_addr" module argument is supplied.

Commit 582ab24e096f ("usb: dwc3: pci: Set "linux,phy_charger_detect" property on some Bay Trail boards") added a new swnode similar to the existing ones for boards where the PHY handles charger detection. Unfortunately, the "linux,sysdev_is_parent" property got lost in the merge conflict resolution of commit ca9400ef7f67 ("Merge 5.17-rc6 into usb-next"). Now dwc3_pci_intel_phy_charger_detect_properties is the only swnode in dwc3-pci that is missing "linux,sysdev_is_parent". It does not seem to cause any obvious functional issues, but it's certainly unintended so restore the line to make the properties consistent again.

2022-06-10usb: dwc3: gadget: Fix IN endpoint max packet size allocationWesley Cheng
The current logic to assign the max packet limit for IN endpoints attempts to take the default HW value and apply the optimal endpoint settings based on it. However, if the default value reports a TxFIFO size large enough for only one max packet, it will divide the value and assign a smaller ep max packet limit. For example, if the default TxFIFO size fits 1024B, current logic will assign 1024/3 = 341B to ep max packet size. If function drivers attempt to request for an endpoint with a wMaxPacketSize of 1024B (SS BULK max packet size) then it will fail, as the gadget is unable to find an endpoint which can fit the requested size. Functionally, if the TxFIFO has enough space to fit one max packet, it will be sufficient, at least when initializing the endpoints.

2022-06-10staging: olpc_dcon: mark driver as brokenJavier Martinez Canillas
The commit eecb3e4e5d9d ("staging: olpc_dcon: add OLPC display controller (DCON) support") added this driver in 2010, and has been in staging since then. It was marked as broken at some point because it didn't even build but that got removed once the build issues were addressed. But it seems that the work to move this driver out of staging has stalled, the last non-trivial change to fix one of the items mentioned in its todo file was commit e40219d5e4b2 ("staging: olpc_dcon: allow simultaneous XO-1 and XO-1.5 support") in 2019. And even if work to destage the driver is resumed, the fbdev subsystem has been deprecated for a long time and instead it should be ported to DRM. Now this driver is preventing to land a kernel wide change, that makes the num_registered_fb symbol to be private to the fbmem.c file. So let's just mark the driver as broken. Someone can then work on making it not depend on the num_registered_fb symbol, allowing to drop the broken dependency again.

2022-06-09nfp: avoid unnecessary check warnings in nfp_app_get_vf_configFei Qin
nfp_net_sriov_check is added in nfp_app_get_vf_config which intends to ensure ivi->vlan_proto and ivi->max_tx_rate/min_tx_rate can be read from VF config table only when firmware supports corresponding capability. However, "nfp_app_get_vf_config" can be called by commands like "ip a", "ip link set $DEV up" and "ip link set $DEV vf $NUM vlan $param" (with VF). When using commands above, many warnings "ndo_set_vf_<cap_x> not supported" would appear if firmware doesn't support VF rate limit and 802.1ad VLAN assingment. If more VFs are created, things could get worse. Thus, this patch add an extra bool parameter for nfp_net_sriov_check to enable/disable the cap check warning report. Unnecessary warnings in nfp_app_get_vf_config can be avoided. Valid warnings in kinds of vf setting function can be reserved.

But admittedly that 'do_bond' usage is fairly complicated, and involves passing it around as an argument to helper functions, so it's somewhat understandable that gcc doesn't see how that all works. This function could be rewritten to make the use of that tracker variable more obviously safe, but for now I'm just adding the forced initialization of it.

2022-06-09iavf: Fix issue with MAC address of VF shown as zeroMichal Wilczynski
After reinitialization of iavf, ice driver gets VIRTCHNL_OP_ADD_ETH_ADDR message with incorrectly set type of MAC address. Hardware address should have is_primary flag set as true. This way ice driver knows what it has to set as a MAC address. Check if the address is primary in iavf_add_filter function and set flag accordingly. To test set all-zero MAC on a VF. This triggers iavf re-initialization and VIRTCHNL_OP_ADD_ETH_ADDR message gets sent to PF. For example: ip link set dev ens785 vf 0 mac 00:00:00:00:00:00 This triggers re-initialization of iavf.

If there was not enough time between those commands the second i40e_vsi_close starts before previous i40e_vsi_close was done which leads to crash.

2022-06-09Revert "mtd: rawnand: add support for Toshiba TC58NVG0S3HTA00 NAND flash"Christian Lamparter
This reverts commit 3380557fc7e28d9bce7607e16d98f123d36da4ca. It turned out this "4-byte" ID might have been an honest mistake. Regrettably, the chip Andreas has might be a counterfeit or is damaged in some other way and shouldn't have ended up in a router. Andreas reported his chip is returning just four bytes: "98 f1 80 15 00 00 00 00". However, according to Kioxia/Toshiba's datasheet, there should have been at least another byte that would have contained the correct OOB size that Andreas needed. Miquel and Andreas are both favoring reverting the patch over further, possibly hacky modifications: "[Reverting] is the safest option here. Apart from this device, we do not know how many devices have these damaged/counterfeit chips. If it is just a couple and only on Fritzboxes, as suggested in the Github issue the patch could be carried through OpenWrt[...]" Thanks to several users on the openwrt forum and github issue, who stayed along for the ride: - Peter-vdL for reporting the issue and testing patches. - neg2led and Hannu Nyman who did all the datasheet digging and debugging.

2022-06-08net: dsa: realtek: rtl8365mb: fix GMII caps for ports with internal PHYAlvin Šipraga
Since commit a18e6521a7d9 ("net: phylink: handle NA interface mode in phylink_fwnode_phy_connect()"), phylib defaults to GMII when no phy-mode or phy-connection-type property is specified in a DSA port node of the device tree. The same commit caused a regression in rtl8365mb whereby phylink would fail to connect, because the driver did not advertise support for GMII for ports with internal PHY. It should be noted that the aforementioned regression is not because the blamed commit was incorrect: on the contrary, the blamed commit is correcting the previous behaviour whereby unspecified phy-mode would cause the internal interface mode to be PHY_INTERFACE_MODE_NA. The rtl8365mb driver only worked by accident before because it _did_ advertise support for PHY_INTERFACE_MODE_NA, despite NA being reserved for internal use by phylink. With one mistake fixed, the other was exposed. Commit a5dba0f207e5 ("net: dsa: rtl8365mb: add GMII as user port mode") then introduced implicit support for GMII mode on ports with internal PHY to allow a PHY connection for device trees where the phy-mode is not explicitly set to "internal". At this point everything was working OK again. Subsequently, commit 6ff6064605e9 ("net: dsa: realtek: convert to phylink_generic_validate()") broke this behaviour again by discarding the usage of rtl8365mb_phy_mode_supported() - where this GMII support was indicated - while switching to the new .phylink_get_caps API. With the new API, rtl8365mb_phy_mode_supported() is no longer needed. Remove it altogether and add back the GMII capability - this time to rtl8365mb_phylink_get_caps() - so that the above default behaviour works for ports with internal PHY again.
