2020-12-07Bluetooth: btusb: Add workaround for remote-wakeup issues with Barrot ↵Hans de Goede
8041a02 fake CSR controllers With the recent btusb change to detect and deal with more fake CSR controllers, I decided to see if fake CSR controllers with Barrot 8041a02 chips would now work. After much experimentation I came to the conclusion that it works, if I have autosuspend enabled initially and then disable it after the device has suspended at least once. Yes this is very weird, but I've tried many things, like manually clearing the remote-wakeup feature. Doing a runtime-resume + runtime suspend is the only way to get the receiver to actually report received data (and/or pairing info) through its bulk rx endpoint. But the funkyness of the bulk-endpoint does not stop there, I mainly found out about this problem, because with autosuspend enabled (which usually ensures the suspend at least once condition is met), the receiver stops reporting received data through its bulk rx endpoint as soon as autosuspend kicks in. So I initially just disabled autosuspend, but then the receiver does not work at all. This was with a fake CSR receiver with a Barrot 8041a02 chip with a bcdDevice value of 0x8891, a lmp_subver of 0x1012, a hci_rev of 0x0810 and a hci_ver of BLUETOOTH_VER_4_0. Summarizing this specific fake CSR receiver has the following 2 issues: 1. The bulk rx endpoint will never report any data unless the device was suspended at least once. 2. They will not wakeup when autosuspended and receiving data on their bulk rx endpoint from e.g. a keyboard or mouse (IOW remote-wakeup support is broken for the bulk endpoint). Add a workaround for 1. which enables runtime-suspend, force-suspends the hci and then wakes-it up by disabling runtime-suspend again. Add a workaround for 2. which clears the hci's can_wake flag, this way the hci will still be autosuspended when it is not open.

2020-12-07Bluetooth: btusb: Fix detection of some fake CSR controllers with a ↵Hans de Goede
bcdDevice val of 0x0134 Commit cde1a8a99287 ("Bluetooth: btusb: Fix and detect most of the Chinese Bluetooth controllers") made the detection of fake controllers more generic fixing it for much of the newer fakes / clones. But this does not work for a fake CSR controller with a bcdDevice value of 0x0134, which was correctly identified as fake before this change. Add an extra check for this special case, checking for a combination of a bcdDevice value of 0x0134, together with a lmp_subver of 0x0c5c and a hci_ver of BLUETOOTH_VER_2_0. The chip inside this fake dongle is marked as with "clockwise cw6629d".

2020-12-07Bluetooth: Change MGMT security info CMD to be more genericDaniel Winkler
For advertising, we wish to know the LE tx power capabilities of the controller in userspace, so this patch edits the Security Info MGMT command to be more generic, such that other various controller capabilities can be included in the EIR data. This change also includes the LE min and max tx power into this newly-named command. The change was tested by manually verifying that the MGMT command returns the tx power range as expected in userspace.

2020-12-07Bluetooth: Use intervals and tx power from mgmt cmdsDaniel Winkler
This patch takes the min/max intervals and tx power optionally provided in mgmt interface, stores them in the advertisement struct, and uses them when configuring the hci requests. While tx power is not used if extended advertising is unavailable, software rotation will use the min and max advertising intervals specified by the client. This change is validated manually by ensuring the min/max intervals are propagated to the controller on both hatch (extended advertising) and kukui (no extended advertising) chromebooks, and that tx power is propagated correctly on hatch. These tests are performed with multiple advertisements simultaneously.

2020-12-07Bluetooth: Break add adv into two mgmt commandsDaniel Winkler
This patch adds support for the new advertising add interface, with the first command setting advertising parameters and the second to set advertising data. The set parameters command allows the caller to leave some fields "unset", with a params bitfield defining which params were purposefully set. Unset parameters will be given defaults when calling hci_add_adv_instance. The data passed to the param mgmt command is allowed to be flexible, so in the future if bluetoothd passes a larger structure with new params, the mgmt command will ignore the unknown members at the end. This change has been validated on both hatch (extended advertising) and kukui (no extended advertising) chromebooks running bluetoothd that support this new interface. I ran the following manual tests: - Set several (3) advertisements using modified test_advertisement.py - For each, validate correct data and parameters in btmon trace - Verified both for software rotation and extended adv Automatic test suite also run, testing many (25) scenarios of single and multi-advertising for data/parameter correctness.

2020-12-07Bluetooth: Fix attempting to set RPA timeout when unsupportedEdward Vear
During controller initialization, an LE Set RPA Timeout command is sent to the controller if supported. However, the value checked to determine if the command is supported is incorrect. Page 1921 of the Bluetooth Core Spec v5.2 shows that bit 2 of octet 35 of the Supported_Commands field corresponds to the LE Set RPA Timeout command, but currently bit 6 of octet 35 is checked. This patch checks the correct value instead. This issue led to the error seen in the following btmon output during initialization of an adapter (rtl8761b) and prevented initialization from completing. < HCI Command: LE Set Resolvable Private Address Timeout (0x08|0x002e) plen 2 Timeout: 900 seconds > HCI Event: Command Complete (0x0e) plen 4 LE Set Resolvable Private Address Timeout (0x08|0x002e) ncmd 2 Status: Unsupported Remote Feature / Unsupported LMP Feature (0x1a) = Close Index: 00:E0:4C:6B:E5:03 The error did not appear when running with this patch.

2020-12-07s390/qeth: make qeth_qdio_handle_aob() more robustJulian Wiedmann
When qeth_qdio_handle_aob() frees dangling allocations in the notified TX buffer, there are rare tear-down cases where qeth_drain_output_queue() would later call qeth_clear_output_buffer() for the same buffer - and thus end up walking the buffer a second time to check for dangling kmem_cache allocations. Luckily current code previously scrubs such a buffer, so qeth_clear_output_buffer() would find buf->buffer->element[i].addr as NULL and not do anything. But this is fragile, and we can easily improve it by consistently clearing the ->is_header flag after freeing the allocation.

Reuse the QETH_QDIO_BUF_EMPTY state to indicate that a TX buffer has been completed with a QAOB notification, and may be cleaned up by qeth_cleanup_handled_pending(). Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-12-07s390/qeth: don't replace a fully completed async TX bufferJulian Wiedmann
For TX buffers that require an additional async notification via QAOB, the TX completion code can now manage all the necessary processing if the notification has already occurred (or is occurring concurrently). In such cases we can avoid replacing the metadata that is associated with the buffer's slot on the ring, and just keep using the current one. As qeth_clear_output_buffer() will also handle any kmem cache-allocated memory that was mapped into the TX buffer, qeth_qdio_handle_aob() doesn't need to worry about it. While at it, also remove the unneeded forward declaration for qeth_init_qdio_out_buf(). Signed-off-by: Julian Wiedmann <jwi@linux.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2020-12-07s390/qeth: use dev->groups for common sysfs attributesJulian Wiedmann
All qeth devices have a minimum set of sysfs attributes, and non-OSN devices share a group of additional attributes. Depending on whether the device is forced to use a specific discipline, the device_type then specifies further attributes. Shift the common attributes into dev->groups, so that the device_type only contains the discipline-specific attributes. This avoids exposing the common attributes to the disciplines, and nicely cleans up our sysfs code. While replacing the qeth_l*_*_device_attributes() helpers, switch from sysfs_*_groups() to the more generic device_*_groups().

2020-12-07s390/ccwgroup: use bus->dev_groups for bus-based sysfs attributesJulian Wiedmann
Bus drivers have their own way of describing the sysfs attributes that all devices on a bus should provide. Switch ccwgroup_attr_groups over to use bus->dev_groups, and thus free up dev->groups for usage by the ccwgroup device drivers. While adjusting the attribute naming, use ATTRIBUTE_GROUPS() to get rid of some boilerplate code.

2020-12-06mlxsw: spectrum_router: Reduce mlxsw_sp_ipip_fib_entry_op_gre4()Jiri Pirko
Turned out that mlxsw_sp_ipip_fib_entry_op_gre4() does not need to figure out the IP address and virtual router id. Those are exactly the same as in the fib_entry it is called for. So just use that and reduce mlxsw_sp_ipip_fib_entry_op_gre4() function to only call mlxsw_sp_ipip_fib_entry_op_gre4_rtdp() make the ipip decap op code similar to nve.

2020-12-06mlxsw: core: Trace EMAD eventsIdo Schimmel
Currently, mlxsw triggers the 'devlink:devlink_hwmsg' tracepoint whenever a request is sent to the device and whenever a response is received from it. However, the tracepoint is not triggered when an event (e.g., port up / down) is received from the device. Also trace EMAD events in order to log a more complete picture of all the exchanged hardware messages. Signed-off-by: Ido Schimmel <idosch@nvidia.com> Signed-off-by: David S.
