Commits pushed to bluez/bluez master during this period:
adapter: Add btd_adapter_send_cmd_event_sync – Bastien Nocera (Red Hat)client: Add mgmt.exp-iso command – Luiz Augusto von Dentz (Intel)bass: Fix crash if setup is freed before bass_bcode_req response – Luiz Augusto von Dentz (Intel)doc/btmon: Add reading output section – Luiz Augusto von Dentz (Intel)Maintainer-driven work across the full stack. On the kernel side, focused on L2CAP protocol correctness, fixing key size checks, ECRED connection request/response handling, and MTU validation. On the BlueZ userspace side, work targeted LE Audio / ISO support (new mgmt.exp-iso command), BASS broadcast stability (crash fix), btmon documentation, and adapter command synchronization improvements. Intel remains the primary driver of both kernel subsystem maintenance and BlueZ upstream development.
Major effort on build system modernization, submitting v8 of a 15-patch meson build system series – the largest single contribution this week. This covers meson wraps, systemd dependency separation, conditional builds, concurrent test execution, and HTML documentation generation/deployment. Additionally contributed portability fixes (big-endian compilation, byte-swapping macros) and reported the 5.86 build failure.
Active across multiple fronts. New hardware enablement with QCC2072 chipset support (v2-v3) and QCA driver refactoring by chipset names. Driver reliability with hci_qca shutdown/power-off naming cleanup and BT power-off on rmmod fix. GATT caching improvements with DB_OUT_OF_SYNC error handling. Also contributed a cross-subsystem patch for deferred probe timeout configuration.
Focused on BTP (Bluetooth Test Protocol) tooling, adding GATT Device Name support to btpclient. Also organized the BlueZ Face-to-Face Meetup in Nice, France for May 2026, driving community engagement.
Working on LE Audio conformance, fixing the CIS host feature condition check in the kernel (v1 and v2 after review feedback from Greg KH).
Addressed broadcast audio stability with a use-after-free fix in BAP broadcast sink cleanup.
Submitted new USB device IDs for MT7922 (0e8d/223c) and MT7925 (0e8d/8c38), expanding hardware support for MediaTek Bluetooth chipsets.
Contributed a socket layer fix, purging error queues in Bluetooth socket destructors to prevent resource leaks.
Engaged in SIG qualification testing, raising issues with TSPC_L2CAP_4_3 settings and asking about GATT server test procedures (GAI/BV-01-C and BV-02-C).
Submitted a Broadcom hardware enablement patch adding BCM4343A2 UART Bluetooth support.
Participated as a reviewer, providing feedback on Qualcomm’s QCC2072 enablement patches.
A security-focused week with two independent vulnerability disclosures: a use-after-free in l2cap_sock_alloc_skb_cb reported by Safa Karakuş, and an SDP OOB heap read via signed/unsigned confusion (CVSS 8.1H, no pairing required).
A landmark week marked by the BlueZ Face-to-Face Meetup announcement (Nice, France, May 30-31) and Bastien Nocera's massive meson build system v9 series (15 patches, 16 messages) proposing a complete build system migration plus HTML documentation generation.
A week dominated by Naga Bhavani Akella's extraordinary Channel Sounding iteration — posting v3 through v10 (8 revisions, 32 messages) of the BlueZ Channel Sounding implementation, making her the most prolific contributor by a wide margin.
