void ath5k_hw_set_bssid_mask(struct ath5k_hw *ah, const u8 *mask)
|
||||||
* ath5k_hw_set_bssid_mask - filter out bssids we listen
|
|
||||||
*
|
|
||||||
* @ah: the &struct ath5k_hw
|
|
||||||
* @mask: the bssid_mask, a u8 array of size ETH_ALEN
|
|
||||||
*
|
|
||||||
* BSSID masking is a method used by AR5212 and newer hardware to inform PCU
|
|
||||||
* which bits of the interface's MAC address should be looked at when trying
|
|
||||||
* to decide which packets to ACK. In station mode and AP mode with a single
|
|
||||||
* BSS every bit matters since we lock to only one BSS. In AP mode with
|
|
||||||
* multiple BSSes (virtual interfaces) not every bit matters because hw must
|
|
||||||
* accept frames for all BSSes and so we tweak some bits of our mac address
|
|
||||||
* in order to have multiple BSSes.
|
|
||||||
*
|
|
||||||
* NOTE: This is a simple filter and does *not* filter out all
|
|
||||||
* relevant frames. Some frames that are not for us might get ACKed from us
|
|
||||||
* by PCU because they just match the mask.
|
|
||||||
*
|
|
||||||
* When handling multiple BSSes you can get the BSSID mask by computing the
|
|
||||||
* set of ~ ( MAC XOR BSSID ) for all bssids we handle.
|
|
||||||
*
|
|
||||||
* When you do this you are essentially computing the common bits of all your
|
|
||||||
* BSSes. Later it is assumed the harware will "and" (&) the BSSID mask with
|
|
||||||
* the MAC address to obtain the relevant bits and compare the result with
|
|
||||||
* (frame's BSSID & mask) to see if they match.
|
|
||||||
*/
|
|
||||||
/*
|
|
||||||
* Simple example: on your card you have have two BSSes you have created with
|
|
||||||
* BSSID-01 and BSSID-02. Lets assume BSSID-01 will not use the MAC address.
|
|
||||||
* There is another BSSID-03 but you are not part of it. For simplicity's sake,
|
|
||||||
* assuming only 4 bits for a mac address and for BSSIDs you can then have:
|
|
||||||
*
|
|
||||||
* \
|
|
||||||
* MAC: 0001 |
|
|
||||||
* BSSID-01: 0100 | --> Belongs to us
|
|
||||||
* BSSID-02: 1001 |
|
|
||||||
* /
|
|
||||||
* -------------------
|
|
||||||
* BSSID-03: 0110 | --> External
|
|
||||||
* -------------------
|
|
||||||
*
|
|
||||||
* Our bssid_mask would then be:
|
|
||||||
*
|
|
||||||
* On loop iteration for BSSID-01:
|
|
||||||
* ~(0001 ^ 0100) -> ~(0101)
|
|
||||||
* -> 1010
|
|
||||||
* bssid_mask = 1010
|
|
||||||
*
|
|
||||||
* On loop iteration for BSSID-02:
|
|
||||||
* bssid_mask &= ~(0001 ^ 1001)
|
|
||||||
* bssid_mask = (1010) & ~(0001 ^ 1001)
|
|
||||||
* bssid_mask = (1010) & ~(1001)
|
|
||||||
* bssid_mask = (1010) & (0110)
|
|
||||||
* bssid_mask = 0010
|
|
||||||
*
|
|
||||||
* A bssid_mask of 0010 means "only pay attention to the second least
|
|
||||||
* significant bit". This is because its the only bit common
|
|
||||||
* amongst the MAC and all BSSIDs we support. To findout what the real
|
|
||||||
* common bit is we can simply "&" the bssid_mask now with any BSSID we have
|
|
||||||
* or our MAC address (we assume the hardware uses the MAC address).
|
|
||||||
*
|
|
||||||
* Now, suppose there's an incoming frame for BSSID-03:
|
|
||||||
*
|
|
||||||
* IFRAME-01: 0110
|
|
||||||
*
|
|
||||||
* An easy eye-inspeciton of this already should tell you that this frame
|
|
||||||
* will not pass our check. This is beacuse the bssid_mask tells the
|
|
||||||
* hardware to only look at the second least significant bit and the
|
|
||||||
* common bit amongst the MAC and BSSIDs is 0, this frame has the 2nd LSB
|
|
||||||
* as 1, which does not match 0.
|
|
||||||
*
|
|
||||||
* So with IFRAME-01 we *assume* the hardware will do:
|
|
||||||
*
|
|
||||||
* allow = (IFRAME-01 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
|
|
||||||
* --> allow = (0110 & 0010) == (0010 & 0001) ? 1 : 0;
|
|
||||||
* --> allow = (0010) == 0000 ? 1 : 0;
|
|
||||||
* --> allow = 0
|
|
||||||
*
|
|
||||||
* Lets now test a frame that should work:
|
|
||||||
*
|
|
||||||
* IFRAME-02: 0001 (we should allow)
|
|
||||||
*
|
|
||||||
* allow = (0001 & 1010) == 1010
|
|
||||||
*
|
|
||||||
* allow = (IFRAME-02 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
|
|
||||||
* --> allow = (0001 & 0010) == (0010 & 0001) ? 1 :0;
|
|
||||||
* --> allow = (0010) == (0010)
|
|
||||||
* --> allow = 1
|
|
||||||
*
|
|
||||||
* Other examples:
|
|
||||||
*
|
|
||||||
* IFRAME-03: 0100 --> allowed
|
|
||||||
* IFRAME-04: 1001 --> allowed
|
|
||||||
* IFRAME-05: 1101 --> allowed but its not for us!!!

/**
|
||||||
|
* ath_hw_set_bssid_mask - filter out bssids we listen
|
||||||
|
*
|
||||||
|
* @common: the ath_common struct for the device.
|
||||||
|
*
|
||||||
|
* BSSID masking is a method used by AR5212 and newer hardware to inform PCU
|
||||||
|
* which bits of the interface's MAC address should be looked at when trying
|
||||||
|
* to decide which packets to ACK. In station mode and AP mode with a single
|
||||||
|
* BSS every bit matters since we lock to only one BSS. In AP mode with
|
||||||
|
* multiple BSSes (virtual interfaces) not every bit matters because hw must
|
||||||
|
* accept frames for all BSSes and so we tweak some bits of our mac address
|
||||||
|
* in order to have multiple BSSes.
|
||||||
|
*
|
||||||
|
* NOTE: This is a simple filter and does *not* filter out all
|
||||||
|
* relevant frames. Some frames that are not for us might get ACKed from us
|
||||||
|
* by PCU because they just match the mask.
|
||||||
|
*
|
||||||
|
* When handling multiple BSSes you can get the BSSID mask by computing the
|
||||||
|
* set of ~ ( MAC XOR BSSID ) for all bssids we handle.
|
||||||
|
*
|
||||||
|
* When you do this you are essentially computing the common bits of all your
|
||||||
|
* BSSes. Later it is assumed the harware will "and" (&) the BSSID mask with
|
||||||
|
* the MAC address to obtain the relevant bits and compare the result with
|
||||||
|
* (frame's BSSID & mask) to see if they match.
|
||||||
|
*
|
||||||
|
* Simple example: on your card you have have two BSSes you have created with
|
||||||
|
* BSSID-01 and BSSID-02. Lets assume BSSID-01 will not use the MAC address.
|
||||||
|
* There is another BSSID-03 but you are not part of it. For simplicity's sake,
|
||||||
|
* assuming only 4 bits for a mac address and for BSSIDs you can then have:
|
||||||
|
*
|
||||||
|
* \
|
||||||
|
* MAC: 0001 |
|
||||||
|
* BSSID-01: 0100 | --> Belongs to us
|
||||||
|
* BSSID-02: 1001 |
|
||||||
|
* /
|
||||||
|
* -------------------
|
||||||
|
* BSSID-03: 0110 | --> External
|
||||||
|
* -------------------
|
||||||
|
*
|
||||||
|
* Our bssid_mask would then be:
|
||||||
|
*
|
||||||
|
* On loop iteration for BSSID-01:
|
||||||
|
* ~(0001 ^ 0100) -> ~(0101)
|
||||||
|
* -> 1010
|
||||||
|
* bssid_mask = 1010
|
||||||
|
*
|
||||||
|
* On loop iteration for BSSID-02:
|
||||||
|
* bssid_mask &= ~(0001 ^ 1001)
|
||||||
|
* bssid_mask = (1010) & ~(0001 ^ 1001)
|
||||||
|
* bssid_mask = (1010) & ~(1001)
|
||||||
|
* bssid_mask = (1010) & (0110)
|
||||||
|
* bssid_mask = 0010
|
||||||
|
*
|
||||||
|
* A bssid_mask of 0010 means "only pay attention to the second least
|
||||||
|
* significant bit". This is because its the only bit common
|
||||||
|
* amongst the MAC and all BSSIDs we support. To findout what the real
|
||||||
|
* common bit is we can simply "&" the bssid_mask now with any BSSID we have
|
||||||
|
* or our MAC address (we assume the hardware uses the MAC address).
|
||||||
|
*
|
||||||
|
* Now, suppose there's an incoming frame for BSSID-03:
|
||||||
|
*
|
||||||
|
* IFRAME-01: 0110
|
||||||
|
*
|
||||||
|
* An easy eye-inspeciton of this already should tell you that this frame
|
||||||
|
* will not pass our check. This is beacuse the bssid_mask tells the
|
||||||
|
* hardware to only look at the second least significant bit and the
|
||||||
|
* common bit amongst the MAC and BSSIDs is 0, this frame has the 2nd LSB
|
||||||
|
* as 1, which does not match 0.
|
||||||
|
*
|
||||||
|
* So with IFRAME-01 we *assume* the hardware will do:
|
||||||
|
*
|
||||||
|
* allow = (IFRAME-01 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
|
||||||
|
* --> allow = (0110 & 0010) == (0010 & 0001) ? 1 : 0;
|
||||||
|
* --> allow = (0010) == 0000 ? 1 : 0;
|
||||||
|
* --> allow = 0
|
||||||
|
*
|
||||||
|
* Lets now test a frame that should work:
|
||||||
|
*
|
||||||
|
* IFRAME-02: 0001 (we should allow)
|
||||||
|
*
|
||||||
|
* allow = (0001 & 1010) == 1010
|
||||||
|
*
|
||||||
|
* allow = (IFRAME-02 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
|
||||||
|
* --> allow = (0001 & 0010) == (0010 & 0001) ? 1 :0;
|
||||||
|
* --> allow = (0010) == (0010)
|
||||||
|
* --> allow = 1
|
||||||
|
*
|
||||||
|
* Other examples:
|
||||||
|
*
|
||||||
|
* IFRAME-03: 0100 --> allowed
|
||||||
|
* IFRAME-04: 1001 --> allowed
|
||||||
|
* IFRAME-05: 1101 --> allowed but its not for us!!!
