CVE-2025-68745
Description
In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Clear cmds after chip reset
Commit aefed3e5548f ('scsi: qla2xxx: target: Fix offline port handling
and host reset handling') caused two problems:
1. Commands sent to FW, after chip reset got stuck and never freed as FW
is not going to respond to them anymore.
2. BUG_ON(cmd->sg_mapped) in qlt_free_cmd(). Commit 26f9ce53817a
('scsi: qla2xxx: Fix missed DMA unmap for aborted commands')
attempted to fix this, but introduced another bug under different
circumstances when two different CPUs were racing to call
qlt_unmap_sg() at the same time: BUG_ON(!valid_dma_direction(dir)) in
dma_unmap_sg_attrs().
So revert 'scsi: qla2xxx: Fix missed DMA unmap for aborted commands' and
partially revert 'scsi: qla2xxx: target: Fix offline port handling and
host reset handling' at __qla2x00_abort_all_cmds.
