Parsing and exposing nontransmitted APs is problematic when underlying HW doesn't support it. Do it only if driver indicated support. Allow HE restriction as well, since the HE spec defined the exact manner that Multiple BSSID set should behave. APs that not support the HE spec will have less predictable Multiple BSSID set support/behavior Signed-off-by:

Previously the transmitted BSS and the non-trasmitted BSS list were defined in struct cfg80211_internal_bss. Move them to struct cfg80211_bss since mac80211 needs this info. Signed-off-by:

When holding data of the non-transmitting BSS, we need to keep the transmitting BSS data on. Otherwise it will be released, and release the non-transmitting BSS with it. Signed-off-by:

Use the new for_each_element() helper here, we cannot use for_each_subelement() since we have a fixed 1 byte before the subelements start. While at it, also fix le16_to_cpup() to be get_unaligned_le16() since we don't know anything about alignment. Signed-off-by: -

This extends cfg80211 BSS table processing to be able to parse Multiple BSSID element from Beacon and Probe Response frames and to update the BSS profiles in internal database for non-transmitted BSSs. Signed-off-by:

This will allow iterating over multiple BSSs inside cfg80211_bss, in case of multiple BSSID. Signed-off-by:

Sara Sharon authored
In multiple BSSID, we have nested IEs inside the multiple BSSID IE, that override the external ones for that specific BSS. As preparation for supporting that, pass 2 BSSIDs to the parse function, the transmitter, and the selected BSSID, so it can know which IEs to choose. If the selected BSSID is NULL, the outer ones will be applied. Change ieee80211_bss_info_update to parse elements itself, instead of receiving them parsed, so we have the relevant bss entry in hand.

This makes for much simpler code, simply walk through all the elements and check that the last one found ends with the end of the data. This works because if any element is malformed the walk is aborted, we end up with a mismatch. Signed-off-by: -

We currently have a number of helpers to find elements that just return a u8 *, change those to return a struct element and add inlines to deal with the u8 * compatibility. Note that the match behaviour is changed to start the natch at the data, so conversion from _ie_match to _elem_match need to be done carefully. Signed-off-by: -
Johannes Berg authored
Instead of open-coding the element walk, use the new macro. Signed-off-by: -
Johannes Berg authored
Rather than always iterating elements from frames with pure u8 pointers, add a type "struct element" that encapsulates the id/datalen/data format of them. Then, add the element iteration macros * for_each_element * for_each_element_id * for_each_element_extid which take, as their first 'argument', such a structure and iterate through a given u8 array interpreting it as elements. While at it and since we'll need it, also add * for_each_subelement * for_each_subelement_id * for_each_subelement_extid which instead of taking data/length just take an outer element and use its data/datalen. Also add for_each_element_completed() to determine if any of the loops above completed, i.e. it was able to parse all of the elements successfully and no data remained. Use for_each_element_id() in cfg80211_find_ie_match() as the first user of this. Signed-off-by:

This makes the age information for cfg80211 scan results more accurate and fixes issues with wpa_supplicant dropping "old" scan results (e.g., "wlan0: Own scan request started a scan in 0.000456 seconds") that looked like would have been received before a scan started due to the inaccuracy of the default timing mechanism for calculating the BSS entry age. This makes hwsim test cases significantly more robust to run. Signed-off-by:

Sven Auhagen reports that if he changes a SFP+ module for a SFP module on the Macchiatobin Single Shot, the link does not come back up. For Sven, it is as easy as: - Insert a SFP+ module connected, and use ping6 to verify link is up. - Remove SFP+ module - Insert SFP 1000base-X module use ping6 to verify link is up: Link up event did not trigger and the link is down but that doesn't show the problem for me. Locally, this has been reproduced by: - Boot with no modules. - Insert SFP+ module, confirm link is up. - Replace module with 25000base-X module. Confirm link is up. - Set remote end down, link is reported as dropped at both ends. - Set remote end up, link is reported up at remote end, but not local end due to lack of link interrupt. Fix this by setting up both GMAC and XLG interrupts for port 0, but only unmasking the appropriate interrupt according to the current mode set in the mac_config() method. However, only do the mask/unmask dance when we are really changing the link mode to avoid missing any link interrupts. Tested-by:

The first patch corrects the binding to correctly reflect hardware that does not come with MDIO cores instantiated. The second patch adds fixed link support to the driver.

Make MDIO child optional and only instantiate the MDIO bus if the child is actually present. There are currently no (in-tree) users of this binding; all (out-of-tree) users use overlays that get shipped together with the FPGA images that contain the IP. This will significantly increase maintainabilty of future revisions of this IP. Reviewed-by:

All users of the fixed_phy_add() pass -1 as GPIO number to the fixed phy driver, and all users of fixed_phy_register() pass -1 as GPIO number as well, except for the device tree MDIO bus. Any new users should create a proper device and pass the GPIO as a descriptor associated with the device so delete the GPIO argument from the calls and drop the code looking requesting a GPIO in fixed_phy_add(). In fixed phy_register(), investigate the "fixed-link" node and pick the GPIO descriptor from "link-gpios" if this property exists. Move the corresponding code out of of_mdio.c as the fixed phy code anyways requires OF to be in use. Tested-by:

Sergei Shtylyov says: ==================== sh_eth: implement simple RX checksum offload Here's a set of 7 patches against DaveM's 'net-next.git' repo. I'm implemeting the simple RX checksum offload (like was done for the 'ravb' driver by Simon Horman); it has been only tested on the R8A7740 and R8A77980 SoCs, the other SoCs should just work (according to their manuals)... ==================== Signed-off-by: -

Add support for the RX checksum offload. This is enabled by default and may be disabled and re-enabled using 'ethtool': # ethtool -K eth0 rx off # ethtool -K eth0 rx on Some Ether MACs provide a simple checksumming scheme which appears to be completely compatible with CHECKSUM_COMPLETE: sum of all packet data after the L2 header is appended to packet data; this may be trivially read by the driver and used to update the skb accordingly. The same checksumming scheme is implemented in the EtherAVB MACs and now supported by the 'ravb' driver. In terms of performance, throughput is close to gigabit line rate with the RX checksum offload both enabled and disabled. The 'perf' output, however, appears to indicate that significantly less time is spent in do_csum() -- this is as expected.

Commit 62e04b7e ("sh_eth: rename 'sh_eth_cpu_data::hw_crc'") renamed the field to 'hw_checksum' for the Ether DMAC "intelligent checksum", however some Ether MACs implement a simpler checksumming scheme, so that name now seems misleading. Rename that field to 'csmr' as the "intelligent checksum" is always controlled by the CSMR register. Signed-off-by:

Replace magic numbers with proper constants. The original patch is from Andrew, I extended / adjusted certain parts: - Use decimal bit numbers. The datasheet uses hex bit numbers 0 ..
