Created attachment 1250316 [details] Testing r92su - Wi-Fi USB driver - r8712u disabled in favour of merged replacement r92su driver Ref. https://github.com/chunkeey/rtl8192su/blob/master/r92su/Kconfig https://git.kernel.org/cgit/linux/kernel/git/gregkh/staging.git/commit/drivers/staging/rtl8712/TODO?id=586add48d https://bugzilla.gnome.org/show_bug.cgi?id=777523 https://bugzilla.redhat.com/show_bug.cgi?id=1421383 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=835822 https://blogs.gnome.org/thaller/2016/08/26/mac-address-spoofing-in-networkmanager-1-4-0 Patched on top of f24 branch - commit aeecde930 https://src.fedoraproject.org/cgit/rpms/kernel.git/commit/?h=f24&id=aeecde930 Fellows, feel free to comment on how best to solve the issue. For cases of problematic MAC change, a workaround is created in the NetworkManager. "device: add spec "driver:" to match devices" https://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=b869d9cc0dda I've tested with the device driven by r8712u.ko and it works OK. [device-scan-rand-mac-addr] match-device=driver:r8712u wifi.scan-rand-mac-address=no Thanks Thomas! *********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 25 kernel bugs. Fedora 25 has now been rebased to 4.10.9-200.fc25. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 26, and are still experiencing this issue, please change the version to Fedora 26. If you experience different issues, please open a new bug report for those. *********** MASS BUG UPDATE ************** This bug is being closed with INSUFFICIENT_DATA as there has not been a response in 2 weeks. If you are still experiencing this issue, please reopen and attach the relevant data from the latest kernel you are running and any data that might have been requested previously. |
Description of problem: The r8712u driver now fails to establish a link Version-Release number of selected component (if applicable): kernel-modules-4.8.6-300.fc25.x86_64 How reproducible: 100% Steps to Reproduce: 1. Insert dongle 2. monitor dmesg -w 3. Observe failure to link Actual results: Link fails Expected results: Link succeeds Additional info: The r8712u driver from the staging area has stopped working in Fedora 25. It works just fine in Fedora 24 and it seems to be substantially unchanged. This driver supports (among others) my emergency USB DLink DWA130 adapter that I use when the laptop's builtin super-duper wireless (Qualcomm Atheros QCA9377 802.11ac) is "too advanced" to connect to some old wireless router. When the dongle is plugged in, this output is written to dmesg -w: [82189.094547] usb 1-4: new high-speed USB device number 7 using xhci_hcd [82189.265676] usb 1-4: New USB device found, idVendor=07d1, idProduct=3300 [82189.265686] usb 1-4: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [82189.265692] usb 1-4: Product: 11n Adapter [82189.265697] usb 1-4: Manufacturer: Manufacturer Realtek [82189.265702] usb 1-4: SerialNumber: 00e04c000001 [82189.269827] r8712u: register rtl8712_netdev_ops to netdev_ops [82189.269839] usb 1-4: r8712u: USB_SPEED_HIGH with 4 endpoints [82189.271387] usb 1-4: r8712u: Boot from EFUSE: Autoload OK [82189.635092] usb 1-4: r8712u: CustomerID = 0x0006 [82189.635100] usb 1-4: r8712u: MAC Address from efuse = 28:10:7b:c2:09:ae [82189.635105] usb 1-4: r8712u: Loading firmware from "rtlwifi/rtl8712u.bin" [82189.686494] IPv6: ADDRCONF(NETDEV_UP): wlan1: link is not ready [82190.390956] r8712u 1-4:1.0 wlan1: 1 RCR=0x153f00e [82190.391691] r8712u 1-4:1.0 wlan1: 2 RCR=0x553f00e [82191.603127] IPv6: ADDRCONF(NETDEV_UP): wlan1: link is not ready [82193.122927] IPv6: ADDRCONF(NETDEV_UP): wlan1: link is not ready [82193.182252] IPv6: ADDRCONF(NETDEV_UP): wlan1: link is not ready [82194.707205] IPv6: ADDRCONF(NETDEV_UP): wlan1: link is not ready [82196.235123] IPv6: ADDRCONF(NETDEV_UP): wlan1: link is not ready ... The IPv6 error messages recur endlessly and the link remains not ready. The interface never is made available to NetworkManager, so the connection cannot proceed. Guidance from poma <pomidorabelisima> showed that an alternate driver for this device is available: https://wireless.wiki.kernel.org/en/users/drivers/rtl819x which says that rtl8192su is intended to replace r8712u. Also, in https://git.kernel.org/cgit/linux/kernel/git/gregkh/staging.git/commit/drivers/staging/rtl8712/TODO?id=586add48d Greg Kroah-Hartman states that "People should not waste time and energy working on this staging driver. And there is a replacement using the kernel wireless stack at: https://github.com/chunkeey/rtl8192su " I have downloaded and installed this software git clone https://github.com/chunkeey/rtl8192su.git followed by manual building and installing and found that the r92su driver therein works perfectly with my USB dongle. Therefore, I request that the r92su drive be added without delay to Fedora 25, and the non-functional r8712u driver be removed.
