2014-11-28cfg80211: leave invalid channels on regdomain changeArik Nemtsov1-0/+12
When the regulatory settings change, some channels might become invalid. Disconnect interfaces acting on these channels, after giving userspace code a grace period to leave them. This mode is currently opt-in, and not all interface operating modes are supported for regulatory-enforcement checks. A wiphy that wishes to use the new enforcement code must specify an appropriate regulatory flag, and all its supported interface modes must be supported by the checking code.

2014-11-28NFC: NCI: Handle Target mode activationJulien Lefrique3-5/+26
Changes: * Extract the Listen mode activation parameters from RF_INTF_ACTIVATED_NTF. * Store the General Bytes of ATR_REQ. * Signal that Target mode is activated in case of an activation in NFC-DEP. * Update the NCI state accordingly. * Use the various constants defined in nfc.h. * Fix the ATR_REQ and ATR_RES maximum size. As per NCI 1.0 and NCI 1.1, the Activation Parameters for both Poll and Listen mode contain all the bytes of ATR_REQ/ATR_RES starting and including Byte 3 as defined in [DIGITAL]. In [DIGITAL], the maximum size of ATR_REQ/ATR_RES is 64 bytes and they are numbered starting from Byte 1.

2014-11-28NFC: digital: Add NFC-DEP Initiator-side ATN SupportMark A. Greer1-0/+1
When an NFC-DEP Initiator times out when waiting for a DEP_RES from the Target, its supposed to send an ATN to the Target. The Target should respond to the ATN with a similar ATN PDU and the Initiator can then resend the last non-ATN PDU that it sent. No more than 'N(retry,atn)' are to be send where 2 <= 'N(retry,atn)' <= 5. If the Initiator had just sent a NACK PDU when the timeout occurred, it is to continue sending NACKs until 'N(retry,nack)' NACKs have been send. This is described in section 14.12.5.6 of the NFC-DEP Digital Protocol Spec. The digital layer's NFC-DEP code doesn't implement this so add that support. The value chosen for 'N(retry,atn)' is 2.

2014-11-28NFC: digital: Add NFC-DEP Target-side NACK SupportMark A. Greer1-0/+3
When an NFC-DEP Target receives a NACK PDU with a PNI equal to 1 less than the current PNI, it is supposed to re-send the last PDU. This is implied in section 14.12.5.4 of the NFC Digital Protocol Spec. The digital layer's NFC-DEP code doesn't implement Target-side NACK handing so add it. The last PDU that was sent is saved in the 'nfc_digital_dev' structure's 'saved_skb' member. The skb will have an additional reference taken to ensure that the skb isn't freed when the driver performs a kfree_skb() on the skb. The length of the skb/PDU is also saved so the length can be restored when re-sending the PDU in the skb (the driver will perform an skb_pull() so an skb_push() needs to be done to restore the skb's data pointer/length).

2014-11-28NFC: digital: Add NFC-DEP Initiator-side NACK SupportMark A. Greer1-0/+2
When an NFC-DEP Initiator receives a frame with an incorrect CRC or with a parity error, and the frame is at least 4 bytes long, its supposed to send a NACK to the Target. The Initiator can send up to 'N(retry,nack)' consecutive NACKs where 2 <= 'N(retry,nack)' <= 5. When the limit is exceeded, a PROTOCOL EXCEPTION is raised. Any other type of transmission error is to be ignored and the Initiator should continue waiting for a new frame. This is described in section 14.12.5.4 of the NFC Digital Protocol Spec. The digital layer's NFC-DEP code doesn't implement any of this so add it. This support diverges from the spec in two significant ways: a) NACKs will be sent for ANY error reported by the driver except a timeout. This is done because there is currently no way for the digital layer to distinguish a CRC or parity error from any other type of error reported by the driver. b) All other errors will cause a PROTOCOL EXCEPTION even frames with CRC errors that are less than 4 bytes. The value chosen for 'N(retry,nack)' is 2. Targets do not send NACK PDUs.

2014-11-28NFC: digital: Add NFC-DEP Send Chaining SupportMark A. Greer1-0/+3
When the NFC-DEP code is given a packet to send that is larger than the peer's maximum payload, its supposed to set the 'MI' bit in the 'I' PDU's Protocol Frame Byte (PFB). Setting this bit indicates that NFC-DEP chaining is to occur. When NFC-DEP chaining is progress, sender 'I' PDUs are acknowledged with 'ACK' PDUs until the last 'I' PDU in the chain (which has the 'MI' bit cleared) is responded to with a normal 'I' PDU. This can occur while in Initiator mode or in Target mode. Sender NFC-DEP chaining is currently not implemented in the digital layer so add that support. Unfortunately, since sending a frame may require writing the CRC to the end of the data, the relevant data part of the original skb must be copied for each intermediate frame.

2014-11-28NFC: digital: Implement NFC-DEP max payload lengthsMark A. Greer1-0/+3
The maximum payload for NFC-DEP exchanges (i.e., the number of bytes between SoD and EoD) is negotiated using the ATR_REQ, ATR_RES, and PSL_REQ commands. The valid maximum lengths are 64, 128, 192, and 254 bytes. Currently, NFC-DEP code assumes that both sides are always using 254 byte maximums and ignores attempts by the peer to change it. Instead, implement the negotiation code, enforce the local maximum when receiving data from the peer, and don't send payloads that exceed the remote's maximum. The default local maximum is 254 bytes.

2014-11-28NFC: digital: Add Target-mode NFC-DEP DID SupportMark A. Greer1-0/+1
When in Target mode, the Initiator specifies whether subsequent DEP_REQ and DEP_RES frames will include a DID byte by the value passed in the ATR_REQ. If the DID value in the ATR_REQ is '0' then no DID byte will be included. If the DID value is between '1' and '14' then a DID byte containing the same value must be included in subsequent DEP_REQ and DEP_RES frames. Any other DID value is invalid. This is specified in sections 14.8.1.2 and 14.8.2.2 of the NFC Digital Protocol Spec. Checking the DID value (if it should be there at all), is not currently supported by the digital layer's NFC-DEP code. Add this support by remembering the DID value in the ATR_REQ, checking the DID value of received DEP_REQ frames (if it should be there at all), and including the remembered DID value in DEP_RES frames when appropriate.

2014-11-26net-timestamp: make tcp_recvmsg call ipv6_recv_error for AF_INET6 socksWillem de Bruijn1-0/+2
TCP timestamping introduced MSG_ERRQUEUE handling for TCP sockets. If the socket is of family AF_INET6, call ipv6_recv_error instead of ip_recv_error. This change is more complex than a single branch due to the loadable ipv6 module. It reuses a pre-existing indirect function call from ping. The ping code is safe to call, because it is part of the core ipv6 module and always present when AF_INET6 sockets are active.

2014-11-25crypto: algif - add and use sock_kzfree_s() instead of memzero_explicit()Daniel Borkmann1-0/+1
Commit e1bd95bf7c25 ("crypto: algif - zeroize IV buffer") and 2a6af25befd0 ("crypto: algif - zeroize message digest buffer") added memzero_explicit() calls on buffers that are later on passed back to sock_kfree_s(). This is a discussed follow-up that, instead, extends the sock API and adds sock_kzfree_s(), which internally uses kzfree() instead of kfree() for passing the buffers back to slab. Having sock_kzfree_s() allows to keep the changes more minimal by just having a drop-in replacement instead of adding memzero_explicit() calls everywhere before sock_kfree_s(). In kzfree(), the compiler is not allowed to optimize the memset() away and thus there's no need for memzero_explicit(). Both, sock_kfree_s() and sock_kzfree_s() are wrappers for __sock_kfree_s() and call into kfree() resp. kzfree(); here, __sock_kfree_s() needs to be explicitly inlined as we want the compiler to optimize the call and condition away and thus it produces e.g. on x86_64 the _same_ assembler output for sock_kfree_s() before and after, and thus also allows for avoiding code duplication.

2014-11-18Bluetooth: Use shorter "rand" name for "randomizer"Johan Hedberg3-19/+19
The common short form of "randomizer" is "rand" in many places (including the Bluetooth specification). The shorter version also makes for easier to read code with less forced line breaks. This patch renames all occurences of "randomizer" to "rand" in the Bluetooth subsystem code.
