Running Ubuntu 16.04 with kernel from http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.9-rc4/ and linux-firmware package version 1.161 on a laptop with an Intel 8260 wireless card. Running `ifconfig wlan0 up` results in a firmware crash. Not sure if it is relevant, but I ran `ip link set dev wlan0 address DE:AD:BE:EF:00:05` before running ifconfig. Stock kernel (4.8.0-22) with stock linux-firmware (1.157.4 containing iwlwifi-8000C-16.ucode) works fine.

No change if I run `ifconfig wlan0 up` without running `ip link set dev wlan0 address ...` first. Stock kernel (4.8.0-22) with linux-firmware 1.161 (containing iwlwifi-8000C-22.ucode) also crashes. Removing the -22 firmware and using -21 (21.302800.0) works fine.

Just for the record, the reporter of bug 187741 (duplicate) saw the same problem happen with 4.8.7.
Created internal bug for tracking.

Matteo, this is a completely differently thing. This error is a firmware bug on an old device for which we don't provide firmware support.
@Emmanuel: I noticed it was on a different bug. I've opened a new bug report specific for my problem: https://bugzilla.kernel.org/show_bug.cgi?id=189651
Paul, could you retest this with our Core release as described in our wiki[1]? Please take Core24 and the new firmware we released in our copy of linux-firmware.git[2]? This is our latest official release and it is on its way to the mainline. [1] https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi/core_release [2] http://git.kernel.org/cgit/linux/kernel/git/iwlwifi/linux-firmware.git/tree/iwlwifi-8000C-27.ucode
I'm having trouble compiling Core24 against 4.10-rc3. First, I got: /home/user/backport-iwlwifi/backport-include/linux/kconfig.h:25:28: error: implicit declaration of function ‘config_enabled’ [-Werror=implicit-function-declaration] #define IS_BUILTIN(option) config_enabled(option) This is apparently due to https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/include/linux/kconfig.h?id=c0a0aba8e478229b2f0956918542152fbad3f794 To fix, I edited backport-include/linux/kconfig.h and replaced: #define IS_BUILTIN(option) config_enabled(option) with: #define IS_BUILTIN(option) __is_defined(option) Now I get several more errors: /home/user/backport-iwlwifi/net/mac80211/status.c:705:38: error: request for member ‘tv64’ in something not a structure or union ts[IEEE80211_TX_LAT_ENTER] = skb_arv.tv64 >> 32; ^ /home/psd/backport-iwlwifi/net/mac80211/status.c:706:15: error: request for member ‘tv64’ in something not a structure or union tmp = skb_arv.tv64 & 0xFFFFFFFF; ^ /home/psd/backport-iwlwifi/net/wireless/nl80211.c:44:8: error: ‘GENL_ID_GENERATE’ undeclared here (not in a function) .id = GENL_ID_GENERATE, /* don't bother with a hardcoded ID */ ^~~~~~~~~~~~~~~~ /home/psd/backport-iwlwifi/net/wireless/nl80211.c:15340:8: error: implicit declaration of function ‘genl_register_family_with_ops_group’ [-Werror=implicit-function-declaration] err = genl_register_family_with_ops_groups(&nl80211_fam, nl80211_ops, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /home/psd/backport-iwlwifi/drivers/net/wireless/intel/iwlwifi/pcie/tx.c:1995:24: error: request for member ‘tv64’ in something not a structure or union s64 ts_1 = skb->tstamp.tv64 >> 32; ^ /home/psd/backport-iwlwifi/drivers/net/wireless/intel/iwlwifi/pcie/tx.c:1998:13: error: request for member ‘tv64’ in something not a structure or union skb->tstamp.tv64 += diff << 16; ^ /home/psd/backport-iwlwifi/drivers/net/wireless/intel/iwlwifi/trans_slave/shared.c:800:32: error: request for member ‘tv64’ in something not a structure or union ts_1 = data_entry->skb->tstamp.tv64 >> 32; ^ /home/psd/backport-iwlwifi/drivers/net/wireless/intel/iwlwifi/trans_slave/shared.c:802:25: error: request for member ‘tv64’ in something not a structure or union data_entry->skb->tstamp.tv64 += diff << 16; ^ I don't have enough time at the moment to work through all of these ... but will look at it again when I have more time.
Created attachment 252731 [details] Fix backport-iwlwifi Core24 on 4.9 Paul, I ran into the same build problems. Thanks to the change set you linked, I came up with this patch. Not sure if the version check is correct, but it works* for me building against kernel 4.9.1. * and by works, it builds successfully, but not necessarily correctly. However the modules do load successfully on reboot.
Created attachment 252741 [details] backport-iwlwifi Core24 on 4.9.1 dmesg Luca, unfortunately I'm still running into failures with 27.455470.0 and release/LinuxCore24:5768:2a86abaf on kernel 4.9.1. If there is more information you need, or different configs I should try, please let me know.
@Matthew Are you using the WLAN device that came with the LENOVO system you have, or you replaced it? Also just as a wild guess, can you try this: diff --git a/drivers/net/wireless/intel/iwlwifi/iwl-drv.c b/drivers/net/wireless/intel/iwlwifi/iwl-drv.c index 8a1825e..617b773 100644 --- a/drivers/net/wireless/intel/iwlwifi/iwl-drv.c +++ b/drivers/net/wireless/intel/iwlwifi/iwl-drv.c @@ -1273,6 +1273,7 @@ fw_dbg_conf: if (tlv_len != sizeof(u32)) goto invalid_tlv_len; paging_mem_size = le32_to_cpup((__le32 *)tlv_data); + break; IWL_DEBUG_FW(drv, "Paging: paging enabled (size = %u bytes)\n", --- (this is a horrid W/A, just trying to see what's going wrong here) thanks.
Created attachment 252881 [details] backport-iwlwifi Core24 on 4.9.1 dmesg with IWL_UCODE_TLV_PAGING break @Emmanuel Yes, it is the original "Intel 8260AC+BT 2x2 vPro" configured at the factory. However I do not know if it has been modified in any way (i.e. firmware updates) due to Windows driver or BIOS/EFI updates. Adding the break changed a handful of the hex codes, but since it's called out in the title: 0x00000309 | ADVANCED_SYSASSERT changed to 0x00100232 | ADVANCED_SYSASSERT and FW error in SYNC CMD FW_PAGING_BLOCK_CMD changed to FW error in SYNC CMD SCAN_CFG_CMD (also just noticed that the old umac data hex codes were 0xDEADBEEF - very cute!)
Ok - so that's a total fiasco. Thanks for trying. It is a vPRO machine.. Hm... Is it provisioned with Intel Active Management Technology?
The .tv64 errors are due to https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2456e855354415bfaeb7badaa14e11b3e02c8466 ... changing tstamp.tv64 to just tstamp fixes those. The genl_* errors are due to https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a07ea4d9941af5a0c6f0be2a71b51ac9c083c5e5 and https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=489111e5c25b93be80340c3113d71903d7c8213 ... this one isn't as straightforward to fix as the other compilation issues. My machine is a Dell 7510 without AMT. I'm using the original Intel 8260 device that came with the machine.
can you paste the output of: sudo hexdump /sys/kernel/debug/ieee80211/phy0/iwlwifi/iwlmvm/nvm_sw Thanks.

Paul, sorry, I haven't got to make our backports work with v4.9+ yet. As you know, the mainline is a moving target and we need to keep adjusting the backports project to keep things compiling and working properly. Thanks for the NVM dump. We will have someone check whether these values are all fine.
I believe my laptop does have AMT, or at least there are BIOS options that I leave disabled. Also, are you interested in the nvm_sw hex dump on a working configuration, a broken configuration, or both?
both is always better :)
My nvm_sw dumps were the same in both a good (4.9.5 and firmware 21.302800.0) and bad state (4.9.5 with Core24 and firmware 27.455470.0). 0000000 0e56 0000 0000 0014 7ffe 0000 0001 0100 0000010 0000 3642 3132 3832 3431 5736 485a 3039 0000020 3231 3033 3430 0000 74bb 4882 04b9 0000 0000030 0909 0306 0006 00c9 0a12 0500 0000 1922 0000040

Switching off power_save did not stop the wireless disconnecting at fairly frequent intervals. (the default seems to be on). # iw dev wlp1s0 get power_save Power save: on
@Mike Cloaked this is a different issue.
OK I will open a new report
We fixed our backport tree. Can someone give it a try? Please use the master branch and not the Core24 branch. Thank you.
Anyone? :)
Sorry for tacking so long. It has been a crazy week. Tested iwlwifi-stack-public:master:5997:1458d072 with firmware version 27.455470.0 Linux 4.9.11 + backport is still broken Linux 4.10.1 + backport is working If interested, I can dump all of the previously requested debugging information for 4.9.
if you use backport, the base kernel shouldn't make any difference. Please paste the output of: ethtool -i <interface name> in both cases?
Created attachment 255079 [details] Debugging info for 4.9.13 and 4.10.1 4.9.13 + backport * dmesg * ethtool * nvm_sw 4.10.1 + backport * dmesg * ethtool * nvm_sw missing due to CONFIG_DEBUG_FS build error
This is ... surprising. You are using the same driver / firmware combo on both kernels, and you get different results?! Timings maybe? I am afraid I won't be able to do much here... Is there anyone else on this bug who could run tests? thank you.
Building the master branch against 4.10.1, I still get tv64 errors: /home/psd/backport-iwlwifi/net/mac80211/status.c:712:38: error: request for member ‘tv64’ in something not a structure or union ts[IEEE80211_TX_LAT_ENTER] = skb_arv.tv64 >> 32; /home/psd/backport-iwlwifi/drivers/net/wireless/intel/iwlwifi/pcie/tx.c:1934:24: error: request for member ‘tv64’ in something not a structure or union s64 ts_1 = skb->tstamp.tv64 >> 32; I changed tstamp.tv64 to just tstamp to get past those, and after that it compiled fine.
Ok - thanks. So let me know how it goes with the firmware assert. Thanks!
Created attachment 255087 [details] Dmesg and other info using 4.10.1 with iwlwifi master No firmware assert ... However, the driver doesn't actually work...
Do you use wicd?
No, I just use wpa_supplicant and /etc/network/interfaces in Ubuntu. When using the master branch driver, wpa_supplicant fails to start: Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: Successfully initialized wpa_supplicant Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: ioctl[SIOCSIWMODE]: Operation not supported Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: ioctl[SIOCGIWRANGE]: Operation not supported Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: ioctl[SIOCGIWMODE]: Operation not supported Mar 5 13:33:32 Mooninite kernel: IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: ioctl[SIOCSIWAP]: Operation not supported Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: ioctl[SIOCSIWESSID]: Operation not supported Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: ioctl[SIOCSIWENCODEEXT]: Operation not supported Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: ioctl[SIOCSIWENCODE]: Operation not supported Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: ioctl[SIOCSIWENCODEEXT]: Operation not supported Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: ioctl[SIOCSIWENCODE]: Operation not supported Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: ioctl[SIOCSIWENCODEEXT]: Operation not supported Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: ioctl[SIOCSIWENCODE]: Operation not supported Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: ioctl[SIOCSIWENCODEEXT]: Operation not supported Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: ioctl[SIOCSIWENCODE]: Operation not supported Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: ioctl[SIOCSIWENCODEEXT]: Operation not supported Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: ioctl[SIOCSIWENCODE]: Operation not supported Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: ioctl[SIOCSIWENCODEEXT]: Operation not supported Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: ioctl[SIOCSIWENCODE]: Operation not supported Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: dbus: wpa_dbus_get_object_properties: failed to get object properties: (none) none Mar 5 13:33:32 Mooninite wpa_supplicant[1517]: dbus: Failed to construct signal Mar 5 13:33:32 Mooninite wpa_supplicant[1532]: ioctl[SIOCSIWSCAN]: Operation not supported Mar 5 13:33:32 Mooninite wpa_supplicant[1532]: wlan0: CTRL-EVENT-SCAN-FAILED ret=-1 retry=1 Disabling wpa_supplicant and all related configuration in /etc/network/interfaces, then manually attempting to bring up the interface results in the output shown in my last attachment.
So please use the nl80211 driver of the supplicant and not wext. Thanks.
Sorry, I was totally unaware of nl80211... nl80211 didn't work with the wpasupplicant in Ubuntu: https://bugs.launchpad.net/ubuntu/+source/wpa/+bug/1670494 However, after patching wpasupplicant, nl80211 works fine for me in kernel 4.9.13, 4.10.0, and 4.10.1. Thanks!
Ok, but what about the original bug?
Original bug is gone ... Using master branch of backport-iwlwifi with firmware 8000C-27 and nl80211 works fine for me on kernel 4.9.13, 4.10.0, and 4.10.1 ... I get no firmware crash on any of those kernels.
Glad to hear.
