      Bluetooth: hci_h5: Add OBDA0623 ACPI HID · e524f252
      由 Hans de Goede 提交于 
      Add OBDA0623 ACPI HID to the acpi_device_id table. This HID is used
for the RTL8723BS Bluetooth part on the Acer Switch 10E SW3-016.

      Bluetooth: revert: hci_h5: close serdev device and free hu in h5_close · 5c3b5796
      由 Hans de Goede 提交于 
      There have been multiple revisions of the patch fix the h5->rx_skb
leak. Accidentally the first revision (which is buggy) and v5 have
both been merged:

v1 commit 70f259a3 ("Bluetooth: hci_h5: close serdev device and free
hu in h5_close");
v5 commit 855af2d7 ("Bluetooth: hci_h5: fix memory leak in h5_close")

The correct v5 makes changes slightly higher up in the h5_close()
function, which allowed both versions to get merged without conflict.

The changes from v1 unconditionally frees the h5 data struct, this
is wrong because in the serdev enumeration case the memory is
allocated in h5_serdev_probe() like this:

        h5 = devm_kzalloc(dev, sizeof(*h5), GFP_KERNEL);

So its lifetime is tied to the lifetime of the driver being bound
to the serdev and it is automatically freed when the driver gets
unbound. In the serdev case the same h5 struct is re-used over
h5_close() and h5_open() calls and thus MUST not be free-ed in
h5_close().

The serdev_device_close() added to h5_close() is incorrect in the
same way, serdev_device_close() is called on driver unbound too and
also MUST no be called from h5_close().

This reverts the changes made by merging v1 of the patch, so that
just the changes of the correct v5 remain.

      Bluetooth: hci_h5: fix memory leak in h5_close · 855af2d7
      由 Anant Thazhemadam 提交于 
      When h5_close() is called, h5 is directly freed when !hu->serdev.
However, h5->rx_skb is not freed, which causes a memory leak.

Freeing h5->rx_skb and setting it to NULL, fixes this memory leak.

      由 Kai-Heng Feng 提交于 
      Some platforms keep USB power even when they are powered off and in S5,
this makes Realtek 8821C keep its firmware even after a cold boot, and
make 8821C never load new firmware.

So use vendor specific HCI command to ask 8821C drop its firmware after
system shutdown.

Newer firmware doesn't have this issue so we only use this trick for old
8821C firmware version.

      Bluetooth: Resume advertising after LE connection · 2943d8ed
      由 Daniel Winkler 提交于 
      When an LE connection request is made, advertising is disabled and never
resumed. When a client has an active advertisement, this is disruptive.
This change adds resume logic for client-configured (non-directed)
advertisements after the connection attempt.

The patch was tested by registering an advertisement, initiating an LE
connection from a remote peer, and verifying that the advertisement is
re-activated after the connection is established. This is performed on
Hatch and Kukui Chromebooks.

      Bluetooth: Fix slab-out-of-bounds read in hci_le_direct_adv_report_evt() · f7e0e8b2

      `num_reports` is not being properly checked. A malformed event packet with
a large `num_reports` number makes hci_le_direct_adv_report_evt() read out
of bounds. Fix it.

      Bluetooth: hci_h5: close serdev device and free hu in h5_close · 70f259a3
      由 Anant Thazhemadam 提交于 
      When h5_close() gets called, the memory allocated for the hu gets
freed only if hu->serdev doesn't exist. This leads to a memory leak.
So when h5_close() is requested, close the serdev device instance and
free the memory allocated to the hu entirely instead.

      Bluetooth: Fix null pointer dereference in hci_event_packet() · 6dfccd13
      由 Anmol Karn 提交于 
      AMP_MGR is getting derefernced in hci_phy_link_complete_evt(), when called
from hci_event_packet() and there is a possibility, that hcon->amp_mgr may
not be found when accessing after initialization of hcon.

- net/bluetooth/hci_event.c:4945
The bug seems to get triggered in this line:

bredr_hcon = hcon->amp_mgr->l2cap_conn->hcon;

Fix it by adding a NULL check for the hcon->amp_mgr before checking the ev-status.
