category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I95B1O
CVE: CVE-2023-52515

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=26788a5b48d9d5cd3283d777d238631c8cd7495a



--------------------------------

[ Upstream commit e193b795 ]

After scmd_eh_abort_handler() has called the SCSI LLD eh_abort_handler
callback, it performs one of the following actions:
* Call scsi_queue_insert().
* Call scsi_finish_command().
* Call scsi_eh_scmd_add().
Hence, SCSI abort handlers must not call scsi_done(). Otherwise all
the above actions would trigger a use-after-free. Hence remove the
scsi_done() call from srp_abort(). Keep the srp_free_req() call
before returning SUCCESS because we may not see the command again if
SUCCESS is returned.
