* net: ipmr: add mfc newroute/delroute netlink supportNikolay Aleksandrov2015-11-301-0/+129
| | | | | | | | | | | | | | | | | | | This patch adds support to add and remove MFC entries. It uses the same attributes like the already present dump support in order to be consistent. There's one new entry - RTA_PREFSRC, it's used to denote an MFC_PROXY entry (see MRT_ADD_MFC vs MRT_ADD_MFC_PROXY). The already existing infrastructure is used to create and delete the entries, the netlink message gets converted internally to a struct mfcctl which is used with ipmr_mfc_add/delete. The other used attributes are: RTA_IIF - used for mfcc_parent (when adding it's required to be valid) RTA_SRC - used for mfcc_origin RTA_DST - used for mfcc_mcastgrp RTA_TABLE - the MRT table id RTA_MULTIPATH - the "oifs" ttl array Signed-off-by: Nikolay Aleksandrov <nikolay@cumulusnetworks.com> Signed-off-by: David S.

| | | | | | | | | | MFC_NOTIFY was introduced in kernel 2.1.68 but afaik it hasn't been used and I couldn't find any users currently so just remove it.

| | | | | | | | | | | It looks like many files are including mroute.h unnecessarily, so remove the include. Most importantly remove it from ipv6.

| * Bluetooth: Fix powering on with privacy and advertisingAndrzej Kaczmarek2015-11-231-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to enable advertising with privacy enabled, SMP has to be registered in order to generate new RPA. During power on, it will be registered at the very end which is the reason why advertising is not enabled and it's not possible to enable it anymore due to mismatch between hci_dev settings and actual controller state. This fixes this problem by moving SMP registration earlier, just after controller is powered (which is ok, because LE SMP will be already able to decide on identity address to be used), but before advertising is enabled.

| * Bluetooth: Simplify request cleanup codeJohan Hedberg2015-11-192-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | The hci_req_sync_cancel() is just as much related to the request cleanup as hci_request_cancel_all() is. Just move the former into the latter and do the cleanup from a single place in hci_dev_do_close(). The important thing is to avoid deadlocks by holding the req_sync lock: previously hci_request_cancel_all was done right after releasing the lock and with this patch it's right before taking it.

| | | | | | | | | | | | | | | | | | | | | | The hci_connect_le_scan() is (as the name implies) a master/central role API, so it makes no sense in passing a role parameter to it. At the same time this patch also fixes the direct advertising support for LE L2CAP sockets where we now call the more appropriate hci_le_connect() API if slave/peripheral role is desired.

| * Bluetooth: Move Stop Discovery to req_workqueueJohan Hedberg2015-11-193-67/+70
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since discovery also deals with LE scanning it makes sense to move it behind the same req_workqueue as other LE scanning changes. This also simplifies the logic since we do many of the actions in a synchronous manner. Part of this refactoring is moving hci_req_stop_discovery() to hci_request.c. At the same time the function receives support for properly handling the STOPPING state since that's the state we'll be in when stopping through the req_workqueue.

| | | | | | | | | | | | | | | | | | | | In some circumstances it may be useful to abort the request through checks done in the request callback.

| | | | | | | | | | | | | | | | | | | | As preparation for moving the discovery HCI commands behind req_workqueue, add a helper and do the validity checks of the given discovery type before proceeding further.

| * Bluetooth: Use req_workqueue for explicit connect requestsJohan Hedberg2015-11-192-36/+18

| * Bluetooth: Add HCI status return parameter to hci_req_sync()Johan Hedberg2015-11-193-18/+24
| | | | | | | | | | | | | | | | | | | | | | In some cases it may be important to get the exact HCI status rather than the converted HCI-to-errno value. Add an optional return parameter to the hci_req_sync() API to allow for this. Since there are no good HCI translation candidates for cancelation and timeout, use the "unknown" status code for those cases.

| * Bluetooth: Add stubs for synchronous HCI request functionalityJohan Hedberg2015-11-193-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | Prepare hci_request.c to have code for doing synchronous HCI requests, such as LE scanning or advertising changes. The necessary work callbacks will be set up in hci_request_setup() and cleaned up in hci_request_cancel_all(). The former is used when an HCI device get registered, and the latter each time it is powered off (or unregistered).

| | | | | | | | | | | | | | | | | | hci_request.c is a more natural place for the synchronous request handling.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To enable controller specific logging, the userspace daemon has to have the ability to log per controller. To facilitate this support, provide a dedicated logging channel. Messages in this channel will be included in the monitor queue and with that also forwarded to monitoring tools along with the actual hardware traces. All messages from the logging channel are timestamped and with that allow an easy correlation between userspace messages and hardware events. This will increase the ability to debug problems faster.
