2024-10-09Revert "wifi: cfg80211: unexport wireless_nlevent_flush()"Johannes Berg
Revert this, I neglected to take into account the fact that cfg80211 itself can be a module, but wext is always builtin. Fixes: aee809aaa2d1 ("wifi: cfg80211: unexport wireless_nlevent_flush()") Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2017-11-02License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman
Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

2017-01-13wext: uninline stream addition functionsJohannes Berg
With 78, 111 and 85 bytes respectively (on x86-64), the functions iwe_stream_add_event(), iwe_stream_add_point() and iwe_stream_add_value() really shouldn't be inlines. It appears that at least my compiler already decided the same, and created a single instance of each one of them for each file using it, but that's still a number of instances in the system overall, which this reduces.

2016-01-29cfg80211/wext: fix message orderingJohannes Berg
Since cfg80211 frequently takes actions from its netdev notifier call, wireless extensions messages could still be ordered badly since the wext netdev notifier, since wext is built into the kernel, runs before the cfg80211 netdev notifier. For example, the following can happen: 5: wlan1: <BROADCAST,MULTICAST> mtu 1500 qdisc mq state DOWN group default link/ether 02:00:00:00:01:00 brd ff:ff:ff:ff:ff:ff 5: wlan1: <BROADCAST,MULTICAST,UP> link/ether when setting the interface down causes the wext message. To also fix this, export the wireless_nlevent_flush() function and also call it from the cfg80211 notifier. Cc: stable@vger.kernel.org Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2006-03-23[PATCH] WE-20 for kernel 2.6.16Jean Tourrilhes
This is version 20 of the Wireless Extensions. This is the completion of the RtNetlink work I started early 2004, it enables the full Wireless Extension API over RtNetlink. Few comments on the patch : o totally driver transparent, no change in drivers needed. o iwevent were already RtNetlink based since they were created (around 2.5.7). This adds all the regular SET and GET requests over RtNetlink, using the exact same mechanism and data format as iwevents. o This is a Kconfig option, as currently most people have no need for it. Surprisingly, patch is actually small and well encapsulated. o Tested on SMP, attention as been paid to make it 64 bits clean. o Code do probably too many checks and could be further optimised, but better safe than sorry. o RtNetlink based version of the Wireless Tools available on my web page for people inclined to try out this stuff.

2005-09-06[PATCH] WE-19 for kernel 2.6.13Jean Tourrilhes
Hi Jeff, This is version 19 of the Wireless Extensions. It was supposed to be the fallback of the WPA API changes, but people seem quite happy about it (especially Jouni), so the patch is rather small. The patch has been fully tested with 2.6.13 and various wireless drivers, and is in its final version. Would you mind pushing that into Linus's kernel so that the driver and the apps can take advantage ot it ? It includes : o iwstat improvement (explicit dBm). This is the result of long discussions with Dan Williams, the authors of NetworkManager. Thanks to him for all the fruitful feedback. o remove pointer from event stream. I was not totally sure if this pointer was 32-64 bits clean, so I'd rather remove it and be at peace with it. o remove linux header from wireless.h. This has long been requested by people writting user space apps, now it's done, and it was not even painful. o final deprecation of spy_offset. You did not like it, it's now gone for good. o Start deprecating dev->get_wireless_stats -> debloat netdev o Add "check" version of event macros for ieee802.11 stack. Jiri Benc doesn't like the current macros, we aim to please ;-) All those changes, except the last one, have been bit-roting on my web pages for a while... Patches for most kernel drivers will follow. Patches for the Orinoco and the HostAP drivers have been sent to their respective maintainers. Have fun...

From: Jean Tourrilhes <jt@bougret.hpl.hp.com> This is the patch to migrate Wireless Extension from WE-16 to WE-17 for kernel 2.6.X. I would like you to queue that patch and submit it to Linus as soon as 2.6.8 is released (so it can be fully tested during 2.6.9). If you want, I can resend that as soon as 2.6.8 is released. The patch is basically unchanged compared to the version posted to the netdev list and my web page one month ago, I just re-diff to the latest kernel (2.6.8-rc2-bk12). The patch already included feedback from various driver maintainers, and nobody else complained, so I guess it's ready. The patch for some drivers inside the kernel will follow (airo.c, wavelan.c, wavelan_cs). Patch for various other drivers (orinoco, hostap, prism54) have been sent already to their maintainers (one month ago) and basically waiting for this patch. Changelog : * - Add flags to frequency -> auto/fixed * - Document (struct iw_quality *)->updated, add new flags (INVALID) * - Wireless Event capability in struct iw_range * - Add support for relative TxPower (yick !) * - Change the way we get to spy_data method for added safety and hostap * - Remove spy #ifdef, they are always on -> cleaner code * - Allow any size GET request if user specifies length > max * - Start migrating get_wireless_stats to struct iw_handler_def * Based on patch from Pavel Roskin <proski@gnu.org> : * - Fix kernel data leak to user space in private handler handling I also added on my page a version of Wireless Tools that use RtNetlink instead of ioctls. This is not as clean as I would like, but is fully functional (if you have WE-19). I know that you were interested, so feel free to send feedback on that...

2002-03-10[PATCH] New wireless driver API part 2Jean Tourrilhes
Quick summary : this patch build on the first part to offer two important new features : o Wireless Events o Wireless Cell Scanning Wireless Events are events generated by device, driver or the wireless subsystem. It allows for example a device to notify user space when it register to a new cell (roaming) or loose contact with the current Access Points. Currently, the other defined events include some configuration changes and packet drop due to excessive retries, more may come in the future. All those events are useful for MobileIP, V-Handoff and Ad-Hoc routing. Wireless Cell Scanning is a generic API to allow device/drive to report Wireless Cells discovered (including ESSID, frequency and QoS). This is similar to what is available in WindowsXP (except that it's compliant to Wireless Extensions). This patch has been submitted for review on this list a couple of time in January, has been on my web page since and used intensively by other people. It was rediffed to 2.5.6. Driver patches have been submitted to maintainers.
