2022-06-29wifi: cfg80211: Allow P2P client interface to indicate port authorizationVinayak Yadawad
In case of 4way handshake offload, cfg80211_port_authorized enables driver to indicate successful 4way handshake to cfg80211 layer. Currently this path of port authorization is restricted to interface type NL80211_IFTYPE_STATION. This patch extends the use of port authorization API for P2P client as well.

2022-06-20cfg80211: Indicate MLO connection info in connect and roam callbacksVeerendranath Jakkam
The MLO links used for connection with an MLD AP are decided by the driver in case of SME offloaded to driver. Add support for the drivers to indicate the information of links used for MLO connection in connect and roam callbacks, update the connected links information in wdev from connect/roam result sent by driver. Also, send the connected links information to userspace. Add a netlink flag attribute to indicate that userspace supports handling of MLO connection. Drivers must not do MLO connection when this flag is not set. This is to maintain backwards compatibility with older supplicant versions which doesn't have support for MLO connection.

2022-06-20wifi: nl80211: expose link ID for associated BSSesJohannes Berg

2022-06-20wifi: cfg80211: add optional link add/remove callbacksJohannes Berg
Add some optional callbacks for link add/remove so that drivers can react here. Initially, I thought it would be sufficient to just create the link in start_ap etc., but it turns out that's not so simple, since there are quite a few callbacks that can be called: if they're erroneously without start_ap, things might crash. Thus it might be easier for drivers to allocate all the necessary data structures immediately, to not have to worry about it in each callback, since cfg80211 checks that the link ID is valid (has been added.)

We wanted to have this sorted by direction (to/from driver), but didn't maintain that well. Sort the file now. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-06-20wifi: nl80211: support MLO in auth/assocJohannes Berg
For authentication, we need the BSS, the link_id and the AP MLD address to create the link and station, (for now) the driver assigns a link address and sends the frame, the MLD address needs to be the address of the interface. For association, pass the list of BSSes that were selected for the MLO connection, along with extra per-STA profile elements, the AP MLD address and the link ID on which the association request should be sent. Note that for now we don't have a proper way to pass the link address(es) and so the driver/mac80211 will select one, but depending on how that selection works it means that assoc w/o auth data still being around (mac80211 implementation detail) the association won't necessarily work - so this will need to be extended in the future to sort out the link addressing.

2022-06-20wifi: cfg80211: mlme: get BSS entry outside cfg80211_mlme_assoc()Johannes Berg
Today it makes more sense to pass the necessary parameters to look up the BSS entry to cfg80211_mlme_assoc(), but with MLO we will need to look up multiple, and that gets awkward. Pull the lookup code into the callers so we can change it better. Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2022-06-20wifi: cfg80211: do some rework towards MLO link APIsJohannes Berg
In order to support multi-link operation with multiple links, start adding some APIs. The notable addition here is to have the link ID in a new nl80211 attribute, that will be used to differentiate the links in many nl80211 operations. So far, this patch adds the netlink NL80211_ATTR_MLO_LINK_ID attribute (as well as the NL80211_ATTR_MLO_LINKS attribute) and plugs it through the system in some places, checking the validity etc. along with other infrastructure needed for it. For now, I've decided to include only the over-the-air link ID in the API. I know we discussed that we eventually need to have to have other ways of identifying a link, but for local AP mode and auth/assoc commands as well as set_key etc. we'll use the OTA ID. Also included in this patch is some refactoring of the data structures in struct wireless_dev, splitting for the first time the data into type dependent pieces, to make reasoning about these things easier.

2022-05-04nl80211: rework internal_flags usageJohannes Berg
Since internal_flags is only 8 bits, we can only have one more internal flag. However, we can obviously never use all of possible the combinations, in fact, we only use 14 of them (including no flags). Since we want more flags for MLO (multi-link operation) in the future, refactor the code to use a flags selector, so wrap all of the .internal_flags assignments in a IFLAGS() macro which selects the combination according to the pre- defined list of combinations. When we need a new combination, we'll have to add it, but again we will never use all possible combinations.

2022-02-04cfg80211: fix race in netlink owner interface destructionJohannes Berg
My previous fix here to fix the deadlock left a race where the exact same deadlock (see the original commit referenced below) can still happen if cfg80211_destroy_ifaces() already runs while nl80211_netlink_notify() is still marking some interfaces as nl_owner_dead. The race happens because we have two loops here - first we dev_close() all the netdevs, and then we destroy them. If we also have two netdevs (first one need only be a wdev though) then we can find one during the first iteration, close it, and go to the second iteration -- but then find two, and try to destroy also the one we didn't close yet. Fix this by only iterating once.

2022-02-04cfg80211/mac80211: assume CHECKSUM_COMPLETE includes SNAPJohannes Berg
There's currently only one driver that reports CHECKSUM_COMPLETE, that is iwlwifi. The current hardware there calculates checksum after the SNAP header, but only RFC 1042 (and some other cases, but replicating the exact hardware logic for corner cases in the driver seemed awkward.) Newer generations of hardware will checksum _including_ the SNAP, which makes things easier. To handle that, simply always assume the checksum _includes_ the SNAP header, which this patch does, requiring to first add it for older iwlwifi hardware, and then remove it again later on conversion. Alternatively, we could have: 1) Always assumed the checksum starts _after_ the SNAP header; the problem with this is that we'd have to replace the exact "what is the SNAP" check in iwlwifi that cfg80211 has. 2) Made it configurable with some flag, but that seemed like too much complexity.

2022-01-08kbuild: do not quote string values in include/config/auto.confMasahiro Yamada
The previous commit fixed up all shell scripts to not include include/config/auto.conf. Now that include/config/auto.conf is only included by Makefiles, we can change it into a more Make-friendly form. Previously, Kconfig output string values enclosed with double-quotes (both in the .config and include/config/auto.conf): CONFIG_X="foo bar" Unlike shell, Make handles double-quotes (and single-quotes as well) verbatim. We must rip them off when used. There are some patterns: [1] $(patsubst "%",%,$(CONFIG_X)) [2] $(CONFIG_X:"%"=%) [3] $(subst ",,$(CONFIG_X)) [4] $(shell echo $(CONFIG_X)) These are not only ugly, but also fragile. [1] and [2] do not work if the value contains spaces, like CONFIG_X=" foo bar " [3] does not work correctly if the value contains double-quotes like CONFIG_X="foo\"bar" [4] seems to work better, but has a cost of forking a process. Anyway, quoted strings were always PITA for our Makefiles. This commit changes Kconfig to stop quoting in include/config/auto.conf. These are the string type symbols referenced in Makefiles or scripts: ACPI_CUSTOM_DSDT_FILE ARC_BUILTIN_DTB_NAME ARC_TUNE_MCPU BUILTIN_DTB_SOURCE CC_IMPLICIT_FALLTHROUGH CC_VERSION_TEXT CFG80211_EXTRA_REGDB_KEYDIR EXTRA_FIRMWARE EXTRA_FIRMWARE_DIR EXTRA_TARGETS H8300_BUILTIN_DTB INITRAMFS_SOURCE LOCALVERSION MODULE_SIG_HASH MODULE_SIG_KEY NDS32_BUILTIN_DTB NIOS2_DTB_SOURCE OPENRISC_BUILTIN_DTB SOC_CANAAN_K210_DTB_SOURCE SYSTEM_BLACKLIST_HASH_LIST SYSTEM_REVOCATION_KEYS SYSTEM_TRUSTED_KEYS TARGET_CPU UNUSED_KSYMS_WHITELIST XILINX_MICROBLAZE0_FAMILY XILINX_MICROBLAZE0_HW_VER XTENSA_VARIANT_NAME I checked them one by one, and fixed up the code where necessary.

2021-12-20cfg80211: Enable regulatory enforcement checks for drivers supporting mesh ifaceSriram R
Currently cfg80211 checks for invalid channels whenever there is a regulatory update and stops the active interfaces if it is operating on an unsupported channel in the new regulatory domain. This is done based on a regulatory flag REGULATORY_IGNORE_STALE_KICKOFF set during wiphy registration which disables this enforcement when unsupported interface modes are supported by driver. Add support to enable this enforcement when Mesh Point interface type is advertised by drivers.
