2015-12-10Bluetooth: btintel: Add manufacturing enter/exit helpersLoic Poulain3-94/+86
Older Intel controllers need to enter manufacturing mode to perform some vendor specific operations (patching, configuration...). Add enter/exit manufaturing methods and refactor existing manufacturing code. Exit can be configured to perform a reset. Reset can be performed either with patches activated or deactivated.

2015-12-10Bluetooth: Clean up current advertising instance trackingJohan Hedberg4-66/+32
We can simplify a lot of code by making sure hdev->cur_adv_instance is always up-to-date. This allows e.g. the removal of the get_current_adv_instance() helper function and the special HCI_ADV_CURRENT value. This patch also makes selecting instance 0x00 explicit in the various calls where advertising instances aren't enabled, e.g. when HCI_ADVERTISING is set or we've just finished enabling LE.

2015-12-10Bluetooth: Clean up advertising initialization in powered_update_hci()Johan Hedberg1-18/+12
The logic in powered_update_hci() to initialize the advertising data & state is a bit more complicated than it needs to be. It was previously not doing anything if HCI_LE_ENABLED wasn't set, but this was not obvious by quickly looking at the code. Now the conditions for the various actions are more explicit. Another simplification is due to the fact that __hci_req_schedule_adv_instance() takes care of setting hdev->cur_adv_instance so there's no need to set it before calling the function.

2015-12-10Bluetooth: Perform HCI update for power on synchronouslyJohan Hedberg5-134/+128
The request to update HCI during power on is always coming either from hdev->req_workqueue or through an ioctl, so it's safe to use hci_req_sync for it. This way we also eliminate potential races with incoming mgmt commands or other actions while powering on. Part of this refactoring is the splitting of mgmt_powered() into mgmt_power_on() and __mgmt_power_off() functions. The main reason is the different requirements as far as hdev locking is concerned, as highlighted with the __ prefix of the power off API. Since the power on in the case of clearing the AUTO_OFF flag cannot be done synchronously in the set_powered mgmt handler, the hci_power_on work callback is extended to cover this (which also simplifies the set_powered helper a lot).

2015-12-10Bluetooth: Move discoverable timeout behind hdev->req_workqueueJohan Hedberg4-53/+28

2015-12-10Bluetooth: Move discoverable changes to hdev->req_workqueueJohan Hedberg3-77/+79
The discoverable mode is intrinsically linked with the connectable mode e.g. through sharing the same HCI command (Write Scan Enable) for BR/EDR. It makes therefore sense to move it to hci_request.c and run the changes through the same hdev->req_workqueue.

2015-12-10Bluetooth: Run page scan updates through hdev->req_workqueueJohan Hedberg5-21/+35
Since Add/Remove Device perform the page scan updates independently from the HCI command completion we've introduced a potential race when multiple mgmt commands are queued. Doing the page scan updates through the req_workqueue ensures that the state changes are performed in a race-free manner. At the same time, to make the request helper more widely usable, extend it to also cover Inquiry Scan changes since those are behind the same HCI command. This is also reflected in the new name of the API as well as the work struct name. Signed-off-by: Johan Hedberg <johan.hedberg@intel.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
2015-12-09cgroup: fix sock_cgroup_data initialization on earlier compilersTejun Heo1-2/+2
sock_cgroup_data is a struct containing an anonymous union. sock_cgroup_set_prioidx() and sock_cgroup_set_classid() were initializing a field inside the anonymous union as follows. struct sock_ccgroup_data skcd_buf = { .val = VAL }; While this is fine on more recent compilers, gcc-4.4.7 triggers the following errors. include/linux/cgroup-defs.h: In function ‘sock_cgroup_set_prioidx’: include/linux/cgroup-defs.h:619: error: unknown field ‘val’ specified in initializer include/linux/cgroup-defs.h:619: warning: missing braces around initializer include/linux/cgroup-defs.h:619: warning: (near initialization for ‘skcd_buf.<anonymous>’) This is because .val belongs to the anonymous union nested inside the struct but the initializer is missing the nesting.

2015-12-08sock, cgroup: add sock->sk_cgroupTejun Heo6-9/+191
In cgroup v1, dealing with cgroup membership was difficult because the number of membership associations was unbound. As a result, cgroup v1 grew several controllers whose primary purpose is either tagging membership or pull in configuration knobs from other subsystems so that cgroup membership test can be avoided. net_cls and net_prio controllers are examples of the latter. They allow configuring network-specific attributes from cgroup side so that network subsystem can avoid testing cgroup membership; unfortunately, these are not only cumbersome but also problematic. Both net_cls and net_prio aren't properly hierarchical. Both inherit configuration from the parent on creation but there's no interaction afterwards. An ancestor doesn't restrict the behavior in its subtree in anyway and configuration changes aren't propagated downwards. Especially when combined with cgroup delegation, this is problematic because delegatees can mess up whatever network configuration implemented at the system level. net_prio would allow the delegatees to set whatever priority value regardless of CAP_NET_ADMIN and net_cls the same for classid. While it is possible to solve these issues from controller side by implementing hierarchical allowable ranges in both controllers, it would involve quite a bit of complexity in the controllers and further obfuscate network configuration as it becomes even more difficult to tell what's actually being configured looking from the network side. While not much can be done for v1 at this point, as membership handling is sane on cgroup v2, it'd be better to make cgroup matching behave like other network matches and classifiers than introducing further complications. In preparation, this patch updates sock->sk_cgrp_data handling so that it points to the v2 cgroup that sock was created in until either net_prio or net_cls is used. Once either of the two is used, sock->sk_cgrp_data reverts to its previous role of carrying prioidx and classid. This is to avoid adding yet another cgroup related field to struct sock. As the mode switching can happen at most once per boot, the switching mechanism is aimed at lowering hot path overhead. It may leak a finite, likely small, number of cgroup refs and report spurious prioidx or classid on switching; however, dynamic updates of prioidx and classid have always been racy and lossy - socks between creation and fd installation are never updated, config changes don't update existing sockets at all, and prioidx may index with dead and recycled cgroup IDs. Non-critical inaccuracies from small race windows won't make any noticeable difference. This patch doesn't make use of the pointer yet. The following patch will implement netfilter match for cgroup2 membership. v2: Use sock_cgroup_data to avoid inflating struct sock w/ another cgroup specific field. v3: Add comments explaining why sock_data_prioidx() and sock_data_classid() use different fallback values.

2015-12-08net: wrap sock->sk_cgrp_prioidx and ->sk_classid inside a structTejun Heo12-38/+76
Introduce sock->sk_cgrp_data which is a struct sock_cgroup_data. ->sk_cgroup_prioidx and ->sk_classid are moved into it. The struct and its accessors are defined in cgroup-defs.h. This is to prepare for overloading the fields with a cgroup pointer. This patch mostly performs equivalent conversions but the followings are noteworthy. * Equality test before updating classid is removed from sock_update_classid(). This shouldn't make any noticeable difference and a similar test will be implemented on the helper side later. * sock_update_netprioidx() now takes struct sock_cgroup_data and can be moved to netprio_cgroup.h without causing include dependency loop. Moved. * The dummy version of sock_update_netprioidx() converted to a static inline function while at it. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-12-08netprio_cgroup: limit the maximum css->id to USHRT_MAXTejun Heo2-5/+14
netprio builds per-netdev contiguous priomap array which is indexed by css->id. The array is allocated using kzalloc() effectively limiting the maximum ID supported to some thousand range. This patch caps the maximum supported css->id to USHRT_MAX which should be way above what is actually useable. This allows reducing sock->sk_cgrp_prioidx to u16 from u32. The freed up part will be used to overload the cgroup related fields. sock->sk_cgrp_prioidx's position is swapped with sk_mark so that the two cgroup related fields are adjacent.
