The firmware-dump consumers qla27xx_fwdt_entry_t264() and\nqla25xx_copy_fce() read ha->fce (NULL check followed by a copy of the\nbuffer) under hardware_lock and never take fce_mutex. A debugfs FCE\ndisable could therefore free the DMA buffer between a dump's NULL check\nand its copy, resulting in a use-after-free.\n\nUnpublish ha->fce under hardware_lock, then release the lock and free\nthe DMA buffer (dma_free_coherent() may sleep). A concurrent dump either\ncompletes its check and copy with the buffer still valid, or observes\nha->fce == NULL and skips it."
