Nilesh Javali <njavali@marvell.com> says: This series collects bug fixes, hardening, and small cleanups for the qla2xxx driver that are independent of the QLA29xx adapter enablement. Most were uncovered by static analysis and fuzzing of the driver's interrupt, mailbox, NVMe, and BSG paths; 30 of the 33 patches carry a Fixes: tag and are marked for stable. The series is organised as follows: Queue pairs, MSI-X, and interrupt setup/teardown Clamp MSI-X derived queue counts to avoid truncation, fix a use-after-free of qpair work on queue teardown, and quiesce the response IRQ before freeing the request queue. Firmware dump, FCE trace, and flash/version paths Improve firmware dump data capture, serialize the flash version read in the reset handler, clarify the MPI optrom address/length units, fix FCE trace enable parsing in debugfs, and fix a use-after-free of the FCE trace during a firmware dump. Probe and mailbox paths Fix the cs84xx use-after-free on host teardown, don't query firmware state while the chip is down, zero the mailbox struct in qla2x00_get_firmware_state(), and null out freed pointers in the qla2x00_mem_alloc() error path. Response/status IOCB path Use memset_io() to clear the QLAFX00 request ring slot, fix response queue over-consumption in __qla_consume_iocb(), fix a soft lockup in the polling continuation IOCB signature, bound rsp_info_len to avoid an out-of-bounds sense-data read, avoid a req_q_map double-read in qla2x00_error_entry(), and reject non-SCSI SRBs on the status IOCB fast path. NPIV and report-ID acquisition Clamp max_npiv_vports to the VP_CTRL bitmap capacity, avoid a double completion on async IOCB timeout, and correct vport handling in report ID acquisition (skip a vport under deletion, drop the vport reference under lock, and hold vport_slock for the host map update). NVMe LS and abort handling Fix an abort reference leak on repeated abort, skip the NVMe LS reject IOCB when firmware is not started, unlink the unsolicited context before freeing on the LS reject error path, and serialize the unsolicited context list with a per-fcport lock. BSG passthrough hardening Use a coherent DMA buffer for D_Port diagnostics, zero-init bsg stack buffers and the SFP DMA buffer to avoid information leaks, validate the BSG request_len before reading vendor_cmd[], and bound i2c->length in the I2C bsg handlers. The final patch bumps the driver version to 12.00.00.2607b2. The series applies on top of the qla2xxx QLA29xx series (v6, 56 patches) on Linux 7.2-rc1.
