This seems to be a simple typo in the debugfs entry for the remote out-of-band data entries. Signed-off-by:

The variable for the out-of-band random number was badly named and with that confusing. Just rename it to local_rand so it is clear what value it represents. Signed-off-by:

It might be a bit counterintuitive to set a 'local' flag based on remote data. This patch adds a clarifying comment to the pairing req/rsp handlers when setting the LOCAL_OOB flag based on the PDU received from the remote side. Signed-off-by:

When we receive the remote public key, if we have remote OOB data there's no point in sending our public key to the remote if the OOB data doesn't match. This patch moves the test for this higher up in the smp_cmd_public_key() function. Signed-off-by:

Johan Hedberg authored
If we haven't received remote OOB data we cannot perform any special checks on the confirm value. This patch updates the check after having received the public key to only perform the verification if we have remote OOB data present. Signed-off-by:

If the SMP Pairing Request or Response PDU received from the remote device indicates that it has received our OOB data we should set the SMP_FLAG_LOCAL_OOB flag. Signed-off-by:

There are several decisions in the SMP logic that depend not only on whether we're doing SMP or not, but also whether local and/or remote OOB data is present. This patch splits the existing SMP_FLAG_OOB into two new flags to track local and remote OOB data respectively. Signed-off-by:

We need to store the local ra/rb value in order to verify the Check value received from the remote. This patch adds a new 'lr' for the local ra/rb value and makes sure it gets used when verifying the DHKey Check PDU received from the remote. Signed-off-by:

The OOB public and secret key pair is different from the non-OOB pairing procedure. SO when OOB method is in use, then use this key pair instead of generating a new one. Signed-off-by:

Then the local out-of-band data for LE SC pairing is requested via Read Local OOB Extended Data command, then fill in the values generated by the smp_generate_oob function. Every call of this command will overwrite previously generated values. Signed-off-by:

This patch adds a smp_generate_oob function that allows to create local out-of-band data that can be used for pairing and also provides the confirmation and random value. Signed-off-by:

The security manager device will require the use of AES-CMAC hash for out-of-band data generation. This patch makes sure it is correctly set up and available. Signed-off-by:

The LE Secure Connections Confirmation Value and LE Secure Connections Random Value contants are required for the out-of-band data and so just define them. Signed-off-by:

Every Bluetooth Low Energy controller requires a local crypto context to handle the resolvable private addresses. At the moment this is just a single crypto context, but for out-of-band data generation it will require an additional. To facility this, create a struct smp_dev that will hold all the extra information. This patch is just the refactoring in preparation for future changes. Signed-off-by:

Within the security manager, it makes sense to use kzfree instead of kfree for all data structures. This ensures that no key material leaks by accident. Signed-off-by:

The HCI_CONN_REMOTE_OOB connection flag is used to indicate if the pairing initiator has provided out-of-band data. However since that value is no longer used in any decision making, just remove it. It is actually unclear what purpose the OOB data present field from the HCI IO Capability Response event serves in the first place. If either side provided out-of-band data, then that data will be used for pairing. Signed-off-by:

When only the pairing initiator is providing out-of-band data, then the receiver side was ignoring the data. For some reason the code was checking if the initiator has received out-of-band data and only then also provide the required inidication that the acceptor actually has the needed data available. For BR/EDR out-of-band pairing it is enough if one side has received out-of-band data. There are no extra checks needed here to make this work smoothly. The only thing that is needed is to tell the controller if data is present (and if it is P-192 or P-256 or both) and then let the controller actually figure out the rest. This means the check for outgoing connection or if the initiator has indicated data are completely pointless and are in fact actually causing harm. The check in question is this one: if (conn->out || test_bit(HCI_CONN_REMOTE_OOB, &conn->flags)) { After just taking the conditional check out and always executing the code for determining the type of out-of-band data, the pairing works flawlessly and prodcudes authenticated link keys. The patch itself looks more complicated due to the reformatting of the indentation, but it essentially just a two-line change. Signed-off-by:

The flags for the management command table used manual encoding of bits in the form of (1 << n). It is however preferred to use BIT(n) macro instead. Signed-off-by:

Changes to the global configuration updates like settings, class of device, name etc. can be received by every user. They are allowed to read them in the first place so provide the updates via events as well. Otherwise untrusted users start polling for updates and that is not a desired behavior. Signed-off-by:

Until now the management interface was restricted to CAP_NET_ADMIN. With this change every user can open the management socket. However the list of commands is heavily restricted to getting basic information about the attached controllers. No access for configuration or other operation is provided. The events are also limited. This is done so that no keys can leak or untrusted users can mess with the Bluetooth configuration. Signed-off-by:

Some management commands are safe to be accessed from any user without special permissions. First step for allowing access to any of these commands from untrusted application is to mark them accordingly. Signed-off-by:

With the introduction of trusted socket flag for control and monitor channels, it is now possible to use a single function for sending packets to these sockets. And with that consolidate the handling. Signed-off-by:

Providing a global trusted flag for management control sockets provides an easy way for identifying sockets and imposing restriction on it. For now all management sockets are trusted since they require CAP_NET_ADMIN. Signed-off-by:

The hci_send_to_flagged_channel helper function can be used to send packets to all channels that have a certain HCI socket flag set. This is especially useful for managment events that are limited to sockets that have first enabled certain functionality. This allows for filtering of events without confusing existing users.

Marcel Holtmann authored
To filter out certain actions for certain HCI sockets introcuce a flags field that allows to configure specific settings on individual sockets. Since the hci_pinfo structure is private in hci_sock.c, provide helper functions for setting and clearing a given flag. Signed-off-by:

Commit cd28a1a9 ("net: dsa: fully divert PHY reads/writes if requested") introduced a check for particular PHYs that need to be accessed using the slave MII bus created by DSA, but this check was too inclusive. This would prevent fixed PHYs from being successfully registered because those should not go through the slave MII bus created by DSA. Make sure we check that the PHY is not a fixed PHY to prevent that from happening. Fixes: cd28a1a9 ("net: dsa: fully divert PHY reads/writes if requested") Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-03-13 This series contains updates to ixgbe and ixgbevf. Don adds additional support for X550 MAC types, which require additional steps around enabling and disabling Rx. Also cleans up variable type inconsistency. I provide a patch to allow relaxed ordering to be enabled on SPARC architectures. Also cleans up ixgbevf whitespace and code comments to align the driver with networking coding standard. Lastly cleaned up uses of memcpy() where ether_addr_copy() could have been used. Alex removes some dead code in the ixgbe cleanup patch. ==================== Signed-off-by:
