Title
scsi: Revert "scsi: qla2xxx: Perform lockless command completion in abort path"
Summary
In the Linux kernel, the following vulnerability has been resolved:
scsi: Revert "scsi: qla2xxx: Perform lockless command completion in abort path"
This reverts commit 0367076b0817d5c75dfb83001ce7ce5c64d803a9.
The commit being reverted added code to __qla2x00_abort_all_cmds() to
call sp->done() without holding a spinlock. But unlike the older code
below it, this new code failed to check sp->cmd_type and just assumed
TYPE_SRB, which results in a jump to an invalid pointer in target-mode
with TYPE_TGT_CMD:

Then commit 4475afa2646d ("scsi: qla2xxx: Complete command early within
lock") added the spinlock back, because not having the lock caused a
race and a crash. But qla2x00_abort_srb() in the switch below already
checks for qla2x00_chip_is_down() and handles it the same way, so the
code above the switch is now redundant and still buggy in target-mode.
Remove it.

"value": "AV:A - An attacker must send FCP traffic from the same Fibre Channel or FCoE fabric as the configured qla2xxx target, making this an adjacent logical-network attack.\nAC:L - An initiator can keep TYPE_TGT_CMD CTIOs outstanding while inducing reset handling through exchange-starvation or repeated ABTS/FCP traffic, so the attacker controls the necessary command and reset conditions.\nPR:N - Dynamic demo-mode node ACL generation is enabled by default, and even a login-only session can submit an unmapped-LUN command that queues a CHECK CONDITION CTIO without target credentials.\nUI:N - After the target is configured and active, malicious fabric traffic alone reaches the vulnerable abort path without victim action.\nS:U - The vulnerable qla2xxx driver and the affected kernel resources share the same security authority; kernel compromise does not itself cross a CVSS scope boundary.\nC:H - The TYPE_TGT_CMD-to-SRB confusion makes sp-\u003edone alias se_cmd.priv; with a pSCSI backend this can target request memory containing attacker-controlled CDB data, making kernel control-flow hijacking and arbitrary memory disclosure defensible.\nI:H - The attacker-influenced indirect call through backend-private command memory can potentially provide kernel code execution and arbitrary modification, rather than being limited to the observed NULL call.\nA:H - The demonstrated result is an invalid supervisor instruction fetch and kernel oops, and repeatable fabric traffic can crash or continually reset the storage target."
