2012-07-10net/rxrpc/ar-peer.c: remove invalid reference to list iterator variableJulia Lawall1-1/+1
If list_for_each_entry, etc complete a traversal of the list, the iterator variable ends up pointing to an address at an offset from the list head, and not a meaningful structure. Thus this value should not be used after the end of the iterator. This seems to be a copy-paste bug from a previous debugging message, and so the meaningless value is just deleted. This problem was found using Coccinelle (http://coccinelle.lip6.fr/). Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: David S. Miller <davem@davemloft.net>

dev->priomap is allocated by extend_netdev_table() called from update_netdev_tables(). And this is only called if write_priomap() is called.

They both can potentially be NULL. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-07-10NFC: Add ISO 14443 type B protocolSamuel Ortiz3-4/+8
Some devices (e.g. Sony's PaSoRi) can not do type B polling, so we have to make a distinction between ISO14443 type A and B poll modes. Cc: Eric Lapuyade <eric.lapuyade@intel.com> Cc: Ilan Elias <ilane@ti.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2012-07-10NFC: Remove warning from nfc_llcp_local_putSamuel Ortiz1-2/+0
The socket local pointer can be NULL when a socket is created but never bound or connected. Reported-by: Sasha Levin <levinsasha928@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-07-10NFC: Handle LLCP Disconnected Mode framesSamuel Ortiz1-0/+44
When receiving such frame, the sockets waiting for a connection to finish should be woken up. Connecting to an unbound LLCP service will trigger a DM as a response. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-07-10NFC: LLCP late bindingSamuel Ortiz2-77/+166
With the LLCP 16 local SAPs we can potentially quickly run out of source SAPs for non well known services. With the so called late binding we will reserve an SAP only when we actually get a client connection for a local service. The SAP will be released once the last client is gone, leaving it available to other services. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-07-10NFC: Forbid SSAP binding to a not well known LLCP serviceSamuel Ortiz1-17/+5
With not Well Known Services there is no guarantees as to which SSAP the server will be listening on, so there is no reason to support binding to a specific source SAP. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-07-10NFC: Forbid LLCP service name reusingSamuel Ortiz1-1/+3
This patch fixes a typo and return the correct error when trying to bind 2 sockets to the same service name. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-07-10NFC: Release LLCP SAP when the owner is releasedSamuel Ortiz3-14/+11
The LLCP SAP should only be freed when the socket owning it is released. As long as the socket is alive, the SAP should be reserved in order to e.g. send the right wks array when bringing the MAC up. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-07-10NFC: Close listening LLCP sockets when the device is goneSamuel Ortiz1-3/+8
When the MAC link goes down, we should only keep the bound sockets alive. They will be closed by sock_release or when the underlying NFC device is moving away. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-07-10NFC: Build LLCP general bytes upon requestSamuel Ortiz1-15/+17
Drivers will need them before starting a poll or when being activated as targets. Mostly WKS can have changed between device registration and then so we need to re-build the whole array. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

Set the right target index and use a better socket declaration routine. Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2012-07-10NFC: Allow HCI driver to pre-open pipes to some gatesEric Lapuyade3-21/+15
Some NFC chips will statically create and open pipes for both standard and proprietary gates. The driver can now pass this information to HCI such that HCI will not attempt to create and open them, but will instead directly use the passed pipe ids.

2012-07-10NFC: nfc_targets_found() should accept zero target foundEric Lapuyade1-6/+13
The semantics for a zero target found event is that the polling operation could not complete. Signed-off-by: Eric Lapuyade <eric.lapuyade@intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-07-10NFC: Core must test the device polling state inside the device lockEric Lapuyade1-2/+7
There can ever be only one call to nfc_targets_found() after polling has been engaged. This could be from a target discovered event from the driver, or from an error handler to notify poll will never complete.

2012-07-10NFC: Implement HCI driver or internal error managementEric Lapuyade1-4/+11
If there is an ongoing HCI command executing, it will be completed, thereby pushing the error up to the core. Otherwise, HCI will directly notify the core with the error. Signed-off-by: Eric Lapuyade <eric.lapuyade@intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-07-10NFC: Factorize HCI cmd completionEric Lapuyade1-11/+16
HCI cmd can be completed either from an HCI response or from an internal driver or HCI error. This requires to factorize the completion code outside of the device lock. Signed-off-by: Eric Lapuyade <eric.lapuyade@intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-07-10NFC: Driver failure APIEric Lapuyade1-0/+10
This API should be used by drivers, HCI, SHDLC or NCI stacks to report an unrecoverable error. Signed-off-by: Eric Lapuyade <eric.lapuyade@intel.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2012-07-10NFC: Changed HCI cmd execution completion result to std linux errnoEric Lapuyade3-22/+23
An HCI command can complete either from an HCI response (with an HCI result) or as a consequence of any other system error during processing. The completion therefore needs to take a standard errno code. The HCI response will convert its result to a standard errno before calling the completion.

2012-07-09mac80211: destroy assoc_data correctly if assoc failsEliad Peller1-4/+2
If association failed due to internal error (e.g. no supported rates IE), we call ieee80211_destroy_assoc_data() with assoc=true, while we actually reject the association. This results in the BSSID not being zeroed out. After passing assoc=false, we no longer have to call sta_info_destroy_addr() explicitly. While on it, move the "associated" message after the assoc_success check.
