Commit 105bdf9e introduced a regression in L2CAP streaming mode due to rearranged initialization code that is shared between ERTM and streaming mode. This change makes sure the transmit queue is initialized in both modes. Signed-off-by:

Commit 94122bbe introduced a problem where tx_send_head was not set to point to the first skb in the ERTM transmit queue, which stalled data transmission. This change sets that pointer when transmission is not already in progress. Reported-by:

The mgmt_ev_device_connected signal must be sent before any event indications happen for sockets associated with the connection. Otherwise e.g. device authorization for the sockets will fail with ENOTCONN as user space things that there is no baseband link. This patch fixes the issue by ensuring that the device_connected event if sent (if it hasn't been so already) as soon as the first ACL data packet arrives from the remote device. Signed-off-by:

It fixes L2CAP socket based security level elevation during a connection. The HID profile needs this (for keyboards) and it is the only way to achieve the security level elevation when using the management interface to talk to the kernel (hence the management enabling patch being the one that exposes this issue). It enables the userspace a security level change when the socket is already connected and create a way to notify the socket the result of the request. At the moment of the request the socket is made non writable, if the request fails the connections closes, otherwise the socket is made writable again, POLL_OUT is emmited. Signed-off-by:

In commit b0302aba, the rtlwifi family of drivers was converted to use asynchronous firmware loading. Unfortumately, the implementation was racy, and the ieee80211 routines could be started before rtl_init_core() was called to setup the data. This patch fixes the bug noted in https://bugzilla.kernel.org/show_bug.cgi?id=43187. Reported-by:

Use more common code for ERTM and streaming mode segmentation and transmission, and begin using skb control block data for delaying extended or enhanced header generation until just before the packet is transmitted. This code is also better suited for resegmentation, which is needed when L2CAP links are reconfigured after an AMP channel move. Signed-off-by:

L2CAP sockets contain a pointer to l2cap_chan that needs to be reference counted in order to prevent a possible dangling pointer when the channel is freed. There were a few other cases where an l2cap_chan pointer on the stack was dereferenced after a call to l2cap_chan_del. Those pointers are also now reference counted. Signed-off-by:

Instead of using modular division, the offset can be calculated using only addition and subtraction. The previous calculation did not work as intended and was more difficult to understand, involving unsigned integer underflow and a check for a negative value where one was not possible.

Currently debugfs commands "hscfgcmd" and "gpiogap" are provided for host sleep configuration. But if user doesn't configure host sleep parameters using these commands, host sleep activation is failed during suspend (support for suspend and resume handlers is added in next patch). Default host sleep configuration is done during driver initialisation in this patch. Signed-off-by:

In order to establish a LE connection we need the address type information. User-space already pass this information to kernel through struct sockaddr_l2. This patch adds the dst_type parameter to l2cap_chan_connect so we are able to pass the address type info from user-space down to hci_conn layer. Signed-off-by:

This patch adds the address type info to struct sockaddr_l2 so user-space can inform the remote device address type required to establish LE connections.

As most LE devices leave advertising mode when they enter the connected state, we may want to "pass" that connection to other users. The first user will be the pairing procedure, the connection is established without an associated socket, after the pairing is complete, userspace may want to discover via GATT what services the newly bonded device has. If userspace establishes the connection while the timeout still hasn't expired, the connection will be re-used. Signed-off-by:

The cid or psm and the source address might not be enough to uniquely identify a global channel, especially when the source address is our own. For instance, when trying to communicate with two LE devices in master mode, data received from the both devices is sent to the same socket. Fix this by taking the destination address into account when choosing the socket. Signed-off-by:

We currently initialize locks, lists, works, etc. in hci_register_dev() (hci_alloc_dev() was added later) which is bogus because an hdev is in an invalid state if it is not registered. This patch moves all memory initialization to hci_alloc_dev(). Device registering and registration of sub-modules is still left in hci_register_dev() as it belongs there. The benefit is (despite cleaning up the code-base) we can now always be sure that an hdev is a valid object and can be locked and worked on even though it may not be registered. This patch also reorders the initialization to be easier to understand. First the memory is initialized, then all generic structures and as last step the sub-init functions are called. This guarantees that all dependencies are initialized in the right order and makes it also easier to find a specific line. We previously initialized it in the same order as the "struct hci_dev" is declared which seems pretty random. Signed-off-by:
