2020-07-14brcmfmac: allow credit borrowing for all access categoriesRaveendran Somu1-24/+37
Current credit borrowing allows only the access category BE to borrow the credits. This change is to fix the credit borrowing logic, to make borrowing available for all access categories and also to borrow only from the lower categories. This fixes WFA 802.11n certs 5.2.27 failures.

The firmware state machines are not fully suitable for concurrent station interface support, it may hit unexpected error if we have 2 different SSIDs and the roaming scenarios concurrently. To avoid the bad user-experience if this is not fully validated, we dis-allow user to create two concurrent station interfaces.

2020-07-14brcmfmac: keep SDIO watchdog running when console_interval is non-zeroWright Feng1-1/+5
brcmfmac host driver makes SDIO bus sleep and stops SDIO watchdog if no pending event or data. As a result, host driver does not poll firmware console buffer before buffer overflow, which leads to missing firmware logs. We should not stop SDIO watchdog if console_interval is non-zero in debug build.

2020-05-29b43_legacy: Fix connection problem with WPA3Larry Finger1-0/+1
Since the driver was first introduced into the kernel, it has only handled the ciphers associated with WEP, WPA, and WPA2. It fails with WPA3 even though mac80211 can handle those additional ciphers in software, b43legacy did not report that it could handle them. By setting MFP_CAPABLE using ieee80211_set_hw(), the problem is fixed. With this change, b43legacy will handle the ciphers it knows in hardware, and let mac80211 handle the others in software. It is not necessary to use the module parameter NOHWCRYPT to turn hardware encryption off. Although this change essentially eliminates that module parameter, I am choosing to keep it for cases where the hardware is broken, and software encryption is required for all ciphers.

In doing this, make brcmf_debugfs_add_entry() return void as no one was even paying attention to the return value.

2020-05-04brcmfmac: remove arp_hostip_clear from brcmf_netdev_stopWright Feng1-3/+0
The firmware does not respond ARP request and causes ping failure with following steps: 1. Bring up interface ifconfig wlan0 up or start wpa_supplicant 2. Set the IP address ifconfig wlan0 192.168.100.10 3. Bring down interface or ifconfig wlan0 down or kill wpa_supplicant 4. Bring up interface again and set the same IP address 5. Connect to AP(192.168.100.1) and ping to AP will be failed. FMAC clears arp_hostip when bringing down the interface, but not set it back if setting the same IP address. We are able to see the IP address in interface info(inconfig wlan0) but the ping still cannot work because the firmware ARP offload does not respond the ARP request. Because of that, we remove "arp_hostip_clear" from function "brcmf_netdev_stop" Signed-off-by: Wright Feng <wright.feng@cypress.com> Signed-off-by: Chi-Hsien Lin <chi-hsien.lin@cypress.com> Reviewed-by: Franky Lin <franky.lin@broadcom.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/1587970803-77700-3-git-send-email-chi-hsien.lin@cypress.com

2020-04-24cfg80211: change internal management frame registration APIJohannes Berg1-12/+7
Almost all drivers below cfg80211 get the API wrong (except for cfg80211) and are unable to cope with multiple registrations for the same frame type, which is valid due to the match filter. This seems to indicate the API is wrong, and we should maintain the full information in cfg80211 instead of the drivers. Change the API to no longer inform the driver about individual registrations and unregistrations, but rather every time about the entire state of the entire wiphy and single wdev, whenever it may have changed. This also simplifies the code in cfg80211 as it no longer has to track exactly what was unregistered and can free things immediately.

2020-04-14b43legacy: Fix case where channel status is corruptedLarry Finger1-0/+1
This patch fixes commit 75388acd0cd8 ("add mac80211-based driver for legacy BCM43xx devices") In https://bugzilla.kernel.org/show_bug.cgi?id=207093, a defect in b43legacy is reported. Upon testing, thus problem exists on PPC and X86 platforms, is present in the oldest kernel tested (3.2), and has been present in the driver since it was first added to the kernel. The problem is a corrupted channel status received from the device. Both the internal card in a PowerBook G4 and the PCMCIA version (Broadcom BCM4306 with PCI ID 14e4:4320) have the problem. Only Rev, 2 (revision 4 of the 802.11 core) of the chip has been tested. No other devices using b43legacy are available for testing. Various sources of the problem were considered. Buffer overrun and other sources of corruption within the driver were rejected because the faulty channel status is always the same, not a random value. It was concluded that the faulty data is coming from the device, probably due to a firmware bug. As that source is not available, the driver must take appropriate action to recover. At present, the driver reports the error, and them continues to process the bad packet. This is believed that to be a mistake, and the correct action is to drop the correpted packet.
