By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Lesser General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) <year> <name of author> + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License along + with this program; if not, write to the Free Software Foundation, Inc., + 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + <signature of Ty Coon>, 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs. If your program is a subroutine library, you may +consider it more useful to permit linking proprietary applications with the +library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License. diff --git a/package/iwinfo/src/Makefile b/package/iwinfo/src/Makefile new file mode 100644 index 000000000..572bef9f9 --- /dev/null +++ b/package/iwinfo/src/Makefile @@ -0,0 +1,44 @@ +IWINFO_BACKENDS = $(BACKENDS) +IWINFO_CFLAGS = $(CFLAGS) -std=gnu99 -fstrict-aliasing -Iinclude + +IWINFO_LIB = libiwinfo.so +IWINFO_LIB_LDFLAGS = $(LDFLAGS) -shared +IWINFO_LIB_OBJ = iwinfo_utils.o iwinfo_wext.o iwinfo_wext_scan.o iwinfo_lib.o + +IWINFO_LUA = iwinfo.so +IWINFO_LUA_LDFLAGS = $(LDFLAGS) -shared -L. -liwinfo -llua +IWINFO_LUA_OBJ = iwinfo_lua.o + +IWINFO_CLI = iwinfo +IWINFO_CLI_LDFLAGS = $(LDFLAGS) -L. -liwinfo +IWINFO_CLI_OBJ = iwinfo_cli.o + + +ifneq ($(filter wl,$(IWINFO_BACKENDS)),) + IWINFO_CFLAGS += -DUSE_WL + IWINFO_LIB_OBJ += iwinfo_wl.o +endif + +ifneq ($(filter madwifi,$(IWINFO_BACKENDS)),) + IWINFO_CFLAGS += -DUSE_MADWIFI + IWINFO_LIB_OBJ += iwinfo_madwifi.o +endif + +ifneq ($(filter nl80211,$(IWINFO_BACKENDS)),) + IWINFO_CFLAGS += -DUSE_NL80211 + IWINFO_CLI_LDFLAGS += -lnl-tiny + IWINFO_LIB_LDFLAGS += -lnl-tiny + IWINFO_LIB_OBJ += iwinfo_nl80211.o +endif + + +%.o: %.c + $(CC) $(IWINFO_CFLAGS) $(FPIC) -c -o $@ $< + +compile: clean $(IWINFO_LIB_OBJ) $(IWINFO_LUA_OBJ) $(IWINFO_CLI_OBJ) + $(CC) $(IWINFO_LIB_LDFLAGS) -o $(IWINFO_LIB) $(IWINFO_LIB_OBJ) + $(CC) $(IWINFO_LUA_LDFLAGS) -o $(IWINFO_LUA) $(IWINFO_LUA_OBJ) + $(CC) $(IWINFO_CLI_LDFLAGS) -o $(IWINFO_CLI) $(IWINFO_CLI_OBJ) + +clean: + rm -f *.o $(IWINFO_LIB) $(IWINFO_LUA) $(IWINFO_CLI) diff --git a/package/iwinfo/src/include/iwinfo.h b/package/iwinfo/src/include/iwinfo.h new file mode 100644 index 000000000..824b94536 --- /dev/null +++ b/package/iwinfo/src/include/iwinfo.h @@ -0,0 +1,143 @@ +#ifndef __IWINFO_H_ +#define __IWINFO_H_ + +#include <sys/types.h> +#include <sys/stat.h> +#include <sys/wait.h> +#include <unistd.h> +#include <stdio.h> +#include <stdlib.h> +#include <string.h> +#include <fcntl.h> +#include <glob.h> +#include <ctype.h> +#include <dirent.h> +#include <stdint.h> + +#include <sys/ioctl.h> +#include <net/if.h> +#include <errno.h> + + +#define IWINFO_BUFSIZE 24 * 1024 +#define IWINFO_ESSID_MAX_SIZE 32 + +#define IWINFO_80211_A (1 << 0) +#define IWINFO_80211_B (1 << 1) +#define IWINFO_80211_G (1 << 2) +#define IWINFO_80211_N (1 << 3) + +#define IWINFO_CIPHER_NONE (1 << 0) +#define IWINFO_CIPHER_WEP40 (1 << 1) +#define IWINFO_CIPHER_TKIP (1 << 2) +#define IWINFO_CIPHER_WRAP (1 << 3) +#define IWINFO_CIPHER_CCMP (1 << 4) +#define IWINFO_CIPHER_WEP104 (1 << 5) +#define IWINFO_CIPHER_AESOCB (1 << 6) +#define IWINFO_CIPHER_CKIP (1 << 7) + +#define IWINFO_KMGMT_NONE (1 << 0) +#define IWINFO_KMGMT_8021x (1 << 1) +#define IWINFO_KMGMT_PSK (1 << 2) + +#define IWINFO_AUTH_OPEN (1 << 0) +#define IWINFO_AUTH_SHARED (1 << 1) + +extern const char *IWINFO_CIPHER_NAMES[];

As an example + * if you are world roaming (regulatory domain set to world or if your + * driver is using a custom world roaming regulatory domain) and while + * doing a passive scan on the 5 GHz band you find an AP there (if not + * on a DFS channel) you will now be able to actively scan for that AP + * or use AP mode on your card on that same channel. Note that this will + * never be used for channels 1-11 on the 2 GHz band as they are always + * enabled world wide. This beacon hint is only sent if your device had + * either disabled active scanning or beaconing on a channel. We send to + * userspace the wiphy on which we removed a restriction from + * (%NL80211_ATTR_WIPHY) and the channel on which this occurred + * before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER) + * the beacon hint was processed. + * + * @NL80211_CMD_AUTHENTICATE: authentication request and notification. + * This command is used both as a command (request to authenticate) and + * as an event on the "mlme" multicast group indicating completion of the + * authentication process. + * When used as a command, %NL80211_ATTR_IFINDEX is used to identify the + * interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and + * BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify + * the SSID (mainly for association, but is included in authentication + * request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used + * to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE + * is used to specify the authentication type. %NL80211_ATTR_IE is used to + * define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs) + * to be added to the frame. + * When used as an event, this reports reception of an Authentication + * frame in station and IBSS modes when the local MLME processed the + * frame, i.e., it was for the local STA and was received in correct + * state. This is similar to MLME-AUTHENTICATE.confirm primitive in the + * MLME SAP interface (kernel providing MLME, userspace SME). The + * included %NL80211_ATTR_FRAME attribute contains the management frame + * (including both the header and frame body, but not FCS). This event is + * also used to indicate if the authentication attempt timed out. In that + * case the %NL80211_ATTR_FRAME attribute is replaced with a + * %NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which + * pending authentication timed out). + * @NL80211_CMD_ASSOCIATE: association request and notification; like + * NL80211_CMD_AUTHENTICATE but for Association and Reassociation + * (similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request, + * MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives). + * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like + * NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to + * MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication + * primitives). + * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like + * NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to + * MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives). + * + * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael + * MIC (part of TKIP) failure; sent on the "mlme" multicast group; the + * event includes %NL80211_ATTR_MAC to describe the source MAC address of + * the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key + * type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and + * %NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this + * event matches with MLME-MICHAELMICFAILURE.indication() primitive + * + * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a + * FREQ attribute (for the initial frequency if no peer can be found) + * and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those + * should be fixed rather than automatically determined. Can only be + * executed on a network interface that is UP, and fixed BSSID/FREQ + * may be rejected. Another optional parameter is the beacon interval, + * given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not + * given defaults to 100 TU (102.4ms). + * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is + * determined by the network interface. + * + * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute + * to identify the device, and the TESTDATA blob attribute to pass through + * to the driver. + * + * @NL80211_CMD_CONNECT: connection request and notification; this command + * requests to connect to a specified network but without separating + * auth and assoc steps. For this, you need to specify the SSID in a + * %NL80211_ATTR_SSID attribute, and can optionally specify the association + * IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_MAC, + * %NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT, + * %NL80211_ATTR_CONTROL_PORT_ETHERTYPE and + * %NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT. + * It is also sent as an event, with the BSSID and response IEs when the + * connection is established or failed to be established. This can be + * determined by the STATUS_CODE attribute. + * @NL80211_CMD_ROAM: request that the card roam (currently not implemented), + * sent as an event when the card/driver roamed by itself. + * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify + * userspace that a connection was dropped by the AP or due to other + * reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and + * %NL80211_ATTR_REASON_CODE attributes are used. + * + * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices + * associated with this wiphy must be down and will follow. + * + * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified + * channel for the specified amount of time. This can be used to do + * off-channel operations like transmit a Public Action frame and wait for + * a response while being associated to an AP on another channel. + * %NL80211_ATTR_IFINDEX is used to specify which interface (and thus + * radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the + * frequency for the operation and %NL80211_ATTR_WIPHY_CHANNEL_TYPE may be + * optionally used to specify additional channel parameters. + * %NL80211_ATTR_DURATION is used to specify the duration in milliseconds + * to remain on the channel.

This command + * requires an interface index, a frame type attribute (optional for + * backward compatibility reasons, if not given assumes action frames) + * and a match attribute containing the first few bytes of the frame + * that should match, e.g. a single byte for only a category match or + * four bytes for vendor frames including the OUI. The registration + * cannot be dropped, but is removed automatically when the netlink + * socket is closed. Multiple registrations can be made. + * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for + * backward compatibility + * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This + * command is used both as a request to transmit a management frame and + * as an event indicating reception of a frame that was not processed in + * kernel code, but is for us (i.e., which may need to be processed in a + * user space application). %NL80211_ATTR_FRAME is used to specify the + * frame contents (including header). %NL80211_ATTR_WIPHY_FREQ (and + * optionally %NL80211_ATTR_WIPHY_CHANNEL_TYPE) is used to indicate on + * which channel the frame is to be transmitted or was received. This + * channel has to be the current channel (remain-on-channel or the + * operational channel). When called, this operation returns a cookie + * (%NL80211_ATTR_COOKIE) that will be included with the TX status event + * pertaining to the TX request. + * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility. + * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame + * transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies + * the TX command and %NL80211_ATTR_FRAME includes the contents of the + * frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged + * the frame. + * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for + * backward compatibility. + * @NL80211_CMD_SET_CQM: Connection quality monitor configuration.
