[WIRELESS] cfg80211: New wireless config infrastructure. This patch creates the core cfg80211 code along with some sysfs bits. This is a stripped down version to allow mac80211 to function, but doesn't include any configuration yet except for creating and removing virtual interfaces. This patch includes the nl80211 header file but it only contains the interface types which the cfg80211 interface for creating virtual interfaces relies on.

cfg80211: add rfkill support To be easier on drivers and users, have cfg80211 register an rfkill structure that drivers can access. When soft-killed, simply take down all interfaces; when hard-killed the driver needs to notify us and we will take down the interfaces after the fact. While rfkilled, interfaces cannot be set UP.

cfg80211: support loading regulatory database as firmware file As the current regulatory database is only about 4k big, and already difficult to extend, we decided that overall it would be better to get rid of the complications with CRDA and load the database into the kernel directly, but in a new format that is extensible. The new file format can be extended since it carries a length field on all the structs that need to be extensible. In order to be able to request firmware when the module initializes, move cfg80211 from subsys_initcall() to the later fs_initcall(); the firmware loader is at the same level but linked earlier, so it can be called from there. Otherwise, when both the firmware loader and cfg80211 are built-in, the request will crash the kernel. We also need to be before device_initcall() so that cfg80211 is available for devices when they initialize. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

cfg80211: introduce nl80211 testmode command This introduces a new NL80211_CMD_TESTMODE for testing and calibration use with nl80211. There's no multiplexing like like iwpriv had, and the command is not available by default, it needs to be explicitly enabled in Kconfig and shouldn't be enabled in most kernels. The command requires a wiphy index or interface index to identify the device to operate on, and the new TESTDATA attribute. There also is API for sending replies to the command, and testmode multicast messages (on a testmode multicast group). I've also updated mac80211 to be able to pass through the command to the driver, since it itself doesn't implement the testmode command. Additionally, to give people an idea of how to use the command, I've added a little code to hwsim that makes use of the new command to set the powersave mode, this is currently done via debugfs and should remain there, and the testmode command only serves as an example of how to use this best -- with nested netlink attributes in the TESTDATA attribute. A hwsim testmode tool can be found at http://git.sipsolutions.net/hwsim.git/. This tool is BSD licensed so people can easily use it as a basis for their own internal fabrication and validation tools.

cfg80211: make spurious warnings less likely, configurable Bob reported that he got warnings in IBSS mode about the ssid_len being zero on a joined event, but only when kmemcheck was enabled. This appears to be due to a race condition between drivers and userspace, when the driver reports joined but the user in the meantime decided to leave the IBSS again, the warning would trigger. This was made more likely by kmemcheck delaying the code that does the check and sends the event. So first, make the warning trigger closer to the driver, which means it's not locked, but since only the warning depends on it that's ok. And secondly, users will not want to have spurious warnings at all, so make those that are known to be racy in such a way configurable.

cfg80211: add CONFIG_CFG80211_CERTIFICATION_ONUS This adds CONFIG_CFG80211_CERTIFICATION_ONUS which is to be used for features / code which require a bit of work on the system integrator's part to ensure that the system will still pass 802.11 regulatory certification. This option is also usable for researchers and experimenters looking to add code in the kernel without impacting compliant code. We'd use CONFIG_EXPERT alone but it seems that most standard Linux distributions are enabling CONFIG_EXPERT already. This allows us to define 802.11 specific kernel features under a flag that is intended by design to be disabled by standard Linux distributions, and only enabled by system integrators or distributions that have done work to ensure regulatory certification on the system with the enabled features.

cfg80211: Enable GO operation on additional channels Allow GO operation on a channel marked with IEEE80211_CHAN_GO_CONCURRENT iff there is an active station interface that is associated to an AP operating on the same channel in the 2 GHz band or the same UNII band (in the 5 GHz band). This relaxation is not allowed if the channel is marked with IEEE80211_CHAN_RADAR. Note that this is a permissive approach to the FCC definitions, that require a clear assessment that the device operating the AP is an authorized master, i.e., with radar detection and DFS capabilities. It is assumed that such restrictions are enforced by user space. Furthermore, it is assumed, that if the conditions that allowed for the operation of the GO on such a channel change, i.e., the station interface disconnected from the AP, it is the responsibility of user space to evacuate the GO from the channel.

cfg80211-wext: export symbols only when needed When a fully converted cfg80211 driver needs cfg80211-wext for userspace API purposes, the symbols need not be exported. When other drivers (orinoco/hermes or ipw2200) are enabled, they do need the symbols exported as they use them directly. Make those drivers select a new CFG80211_WEXT_EXPORT Kconfig symbol (instead of just CFG80211_WEXT) and export the functions only if requested - this saves about 1/2k due to the size of EXPORT_SYMBOL() itself.

cfg80211: add missing dependency to CFG80211 suboptions New options introduced by the patch this fixes are still enabled even if CFG80211 is disabled. .config: # CONFIG_CFG80211 is not set CONFIG_CFG80211_REQUIRE_SIGNED_REGDB=y CONFIG_CFG80211_USE_KERNEL_REGDB_KEYS=y # CONFIG_LIB80211 is not set When CFG80211_REQUIRE_SIGNED_REGDB is enabled, it selects SYSTEM_DATA_VERIFICATION which selects SYSTEM_TRUSTED_KEYRING that need extract-cert tool. extract-cert needs some openssl headers to be installed on the build machine. Instead of adding missing "depends on CFG80211", it's easier to use a 'if' block around all options related to CFG80211, so do that.

lib80211: absorb crypto bits from net/ieee80211 These bits are shared already between ipw2x00 and hostap, and could probably be shared both more cleanly and with other drivers. This commit simply relocates the code to lib80211 and adjusts the drivers appropriately. Signed-off-by: John W. Linville <linville@tuxdriver.com>

net/lib80211: move WEP handling to ARC4 library code The crypto API abstraction is not very useful for invoking ciphers directly, especially in the case of arc4, which only has a generic implementation in C. So let's invoke the library code directly. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
