the Linux kernel, the following vulnerability has been resolved:\n\nsoc: fsl: qbman: fix race condition in qman_destroy_fq\n\nWhen QMAN_FQ_FLAG_DYNAMIC_FQID is set, there's a race condition between\nfq_table[fq->idx] state and freeing/allocating from the pool and\nWARN_ON(fq_table[fq->idx]) in qman_create_fq() gets triggered.\n\nIndeed, we can have:\n         Thread A                             Thread B\n    qman_destroy_fq()                    qman_create_fq()\n      qman_release_fqid()\n        qman_shutdown_fq()\n        gen_pool_free()\n           -- At this point, the fqid is

fq_table[fq->idx] = fq;\n     fq_table[fq->idx] = NULL;\n\nAnd adding some logs between qman_release_fqid() and\nfq_table[fq->idx] = NULL makes the WARN_ON() trigger a lot more.\n\nTo prevent that,
