2022-02-04mac80211: vht: use HE macros for parsing HE capabilitiesMordechay Goodstein
IEEE80211_VHT_MCS_NOT_SUPPORTED and IEEE80211_HE_MCS_NOT_SUPPORTED have the same value so no real bug, but for code integrity use the HE macros for parsing HE capabilities.

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.

2022-02-04mac80211: consider RX NSS in UHB connectionMordechay Goodstein

2022-01-28brcmfmac: use ISO3166 country code and 0 rev as fallback on some devicesHans de Goede
This is a second attempt at honering the country code send out by access points. This was first added in commit b0b524f079a2 ("brcmfmac: use ISO3166 country code and 0 rev as fallback"). Subsequently this was reverted in commit 151a7c12c4fc ("Revert "brcmfmac: use ISO3166 country code and 0 rev as fallback""), because it was causing issues with AP mode on some brcmfmac models (specifically on BCM4359/9). Many devices ship with a nvram ccode value of X2/XT/XU/XV/ALL which are all special world-wide compatibility ccode-s. Most of these world-wide ccode-s allow passive scan mode only for 2.4GHz channels 12-14, only enabling them when an AP is seen on them. But at least on brcmfmac43455 devices this is not working correctly, these do not see accesspoints on channels 12-14 unless the ccode is changes to a country where these channels are allowed. Translating received country codes to an ISO3166 country code and 0 rev ccreq fixes devices using a brcmfmac43455 with a X2/XT/XU/XV/ALL ccode not seeing accesspoints on channels 12-14. To avoid this causing issues on other brcmfmac models again, the fallback is limited to only brcmfmac4345* chips this time.

2022-01-28rtw89: rename vif_maintain to role_maintainPing-Ke Shih
The H2C_FUNC_MAC_FWROLE_MAINTAIN also maintains the roles of all connected stations; not just the role of VIF. So, I correct the name, but don't change the logic at all.

2022-01-28rtw89: extend firmware commands on states of sta_assoc and sta_disconnectPing-Ke Shih
The h2c_join firmware command is used to indicate a station is connected, and the assoc_cmac_tbl firmware command is used to set CMAC table corresponding to a mac_id. Both commands must work in both station and AP modes. Use the mac_id of rtw89_sta naturally and intuitively.

Update beacon content if TIM bitmap maintained by mac80211 is changed. Since .set_tim must be atomic but driver uses mutex lock, we add a work.

2022-01-28rtw89: correct use of BA CAMPing-Ke Shih
BA CAM is used to ACK peer's packets, so it must be established when IEEE80211_AMPDU_RX_START, and free it by IEEE80211_AMPDU_RX_STOP. The hardware can support two static BA CAM entries, so I implement a bitmap and a struct to record which entry is used and its corresponding tid. Also, the hardware can learn and create dynamic BA CAM entries automatically if received packets don't match static BA CAM. That means it can still work if we don't use H2C to set static BA CAM. An exception is tid=0 should be always allocated in static BA CAM, so an existing static BA CAM will be replaced if it is full and peer is going to establish a BA with tid=0. The new firmware use new format of this H2C, so I upgrade it as well.

2022-01-28rtw89: encapsulate RX handlers to single functionPing-Ke Shih

2022-01-28rtw89: extract modules by chipsetZong-Zhe Yang
We are planning to support more chipsets, e.g. 8852C. Before that, we consider architecutre to handle multiple kinds of chipsets. Obviosuly, based on original design, rtw89_core module will have large size even if there is only one chipset under running. It is because all chipset related things are put in rtw89_core now. To reduce such overhead, we extract modules of rtw89 and adjust dependencies between modules. The following assumes that 8852AE, 8852AU, and 8852CE are all supported, we describe the difference before and after extraction. [Before extraction] ------------- |------------------------------------ | rtw89_usb | V ------------- --------------------------------------- ------------- | rtw89_core (including 8852A, 8852C) | <--- | rtw89_pci | --------------------------------------- ------------- The data of 8852A and 8852C are built in rtw89_core. And rtw89_pci is the entry of 8852AE and 8852CE. And rtw89_usb is the entry of 8852AU. [After extraction] ------------- ---------------- |----------- | rtw89_usb | <-------- | rtw89_8852au | | ------------- ---------------- V --------------- | -------------- | | <--------------- | rtw89_core | <--- | rtw89_8852a | -------------- | | <--------------- ^ ^ --------------- | | | ------------- ---------------- | | | | <-------- | rtw89_8852ae | | |----------- | rtw89_pci | ---------------- | | | <----------------- | ------------- | | --------------- ---------------- |--------------- | rtw89_8852c | <------ | rtw89_8852ce | --------------- ---------------- The data of 8852A/8852C is extracted to rtw89_8852a/rtw89_8852c. And rtw89_pci/rtw89_usb handles only common flow of pci/usb bus. Finally, 8852AE, 8852AU, and 8852CE have individual entry modules, i.e. rtw89_8852ae, rtw89_8852au, and rtw89_8852ce correspondingly.
