Instead of calling ieee80211_recalc_txpower on monitor interfaces directly, call it using the virtual monitor interface, if one exists. In case of a single monitor interface given, reject setting TX power, if no virtual monitor interface exists. That being checked, don't warn in ieee80211_bss_info_change_notify, after setting TX power on a monitor interface. Fixes warning: ------------[ cut here ]------------ WARNING: CPU: 0 PID: 2193 at net/mac80211/driver-ops.h:167 ieee80211_bss_info_change_notify+0x111/0x190 Modules linked in: uvcvideo videobuf2_vmalloc videobuf2_memops videobuf2_v4l2 videobuf2_core rndis_host cdc_ether usbnet mii tp_smapi(O) thinkpad_ec(O) ohci_hcd vboxpci(O) vboxnetadp(O) vboxnetflt(O) v boxdrv(O) x86_pkg_temp_thermal kvm_intel kvm irqbypass iwldvm iwlwifi ehci_pci ehci_hcd tpm_tis tpm_tis_core tpm CPU: 0 PID: 2193 Comm: iw Tainted: G O 4.12.12-gentoo #2 task: ffff880186fd5cc0 task.stack: ffffc90001b54000 RIP: 0010:ieee80211_bss_info_change_notify+0x111/0x190 RSP: 0018:ffffc90001b57a10 EFLAGS: 00010246 RAX: 0000000000000006 RBX: ffff8801052ce840 RCX: 0000000000000064 RDX: 00000000fffffffc RSI: 0000000000040000 RDI: ffff8801052ce840 RBP: ffffc90001b57a38 R08: 0000000000000062 R09: 0000000000000000 R10: ffff8802144b5000 R11: ffff880049dc4614 R12: 0000000000040000 R13: 0000000000000064 R14: ffff8802105f0760 R15: ffffc90001b57b48 FS: 00007f92644b4580(0000) GS:ffff88021e200000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 00007f9263c109f0 CR3: 00000001df850000 CR4: 00000000000406f0 Call Trace: ieee80211_recalc_txpower+0x33/0x40 ieee80211_set_tx_power+0x40/0x180 nl80211_set_wiphy+0x32e/0x950 Reported-by: Peter Große <pegro@friiks.de> Signed-off-by: Peter Große <pegro@friiks.de> Signed-off-by: Johannes Berg <johannes.berg@intel.com> |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
