…GRESS` Fix discrepancy in reference management between calls to `bt_l2cap_chan_ops.recv` when the application returns `-EINPROGRESS`. There are two call sites, `l2cap_chan_le_recv_sdu` and `l2cap_chan_le_recv`, that were inconsistent. `l2cap_chan_le_recv_sdu` moves the reference, and this patch updates `l2cap_chan_le_recv` to do the same. This behavior is also now documented. This bug has existed since the introduction of this feature in 3151d26.

…00_00_00_00_` This is shorthand for random static addresses. It's similar to `bt_addr_le_from_str`, but is a macro that results in an object literal, making it more versatile and less verbose. This macro only gives access to the first 255 random static addresses, but this ought to be enough addresses for testing.

The test implementation is based on a copy of the HFC multilink test. The test verifies that the stack respects the reference counting of SDU buffers when the L2CAP -EINPROGRESS feature is used. Signed-off-by: Aleksander Wasaznik <[email protected]> (cherry picked from commit 47325f8)
…uide docs for 4.1 This introduces the release notes and migration guide for 4.1.0 earlier than we typically do, so that people have a placeholder to start adding content as they line up pull requests for 4.1. The two documents are currently orphan and not visible from the main documentation as this would confuse users of 4.0. Signed-off-by: Benjamin Cabé <[email protected]> (cherry picked from commit d342f9e)
Because the number of ACL RX buffers must be at least the number of maximum connections plus one, increasing `CONFIG_BT_MAX_CONN` could inadvertently lead to a build failure if the number of ACL RX buffers is not also increased. This dependency may not be obvious to users. To address this issue, this commit deprecates the `CONFIG_BT_BUF_RX_COUNT` Kconfig symbol and computes the value in `buf.h` using the new `BT_BUF_RX_COUNT` define. Note that the default value and the minimum range value have been changed to 0 to "disable" the option. Additionally, to allow users to increase the number of ACL RX buffers, this commit introduces the new `CONFIG_BT_BUF_RX_COUNT_EXTRA` Kconfig symbol. The value of this symbol will be added to the computed value of `BT_BUF_RX_COUNT`. The configurations of tests and samples have been updated to reflect these changes.

…pool The Bluetooth data buffer API currently lacks a mechanism to notify when a buffer is freed in the RX pool. This limitation forces HCI drivers to adopt inefficient workarounds to manage buffer allocation. HCI drivers face two suboptimal options: - Blocking calls: Use bt_buf_get_rx with K_FOREVER, which blocks the execution context until a buffer becomes available. - Polling: Repeatedly call bt_buf_get_rx with K_NO_WAIT, which increases CPU load and reduces efficiency. This commit introduces a callback mechanism that is triggered each time a buffer is freed in the RX pool. With this feature, HCI drivers can: - Call bt_buf_get_rx with K_NO_WAIT. - Wait for the callback notification if a NULL buffer is returned, avoiding unnecessary polling. The new callback improves efficiency by enabling event-driven behavior for buffer management, reducing CPU overhead while maintaining responsiveness.

This commit adds a unit test that checks the freed buffer callback of the bluetooth data buffer API. Signed-off-by: Pavel Vasilyev <[email protected]> (cherry picked from commit 0d06691)
