Takashi Sakamoto c6b51091ca firewire: cdev: fix back-transition for iso_resource_auto client resource ... The todo member of iso_resource_auto structure represents the state of the client resource and normally transitions in the following order: ISO_RES_AUTO_ALLOC -> ISO_RES_AUTO_REALLOC -> ISO_RES_AUTO_DEALLOC However, concurrent access from the work item and the file descriptor release function can cause the state to transition backwards from ISO_RES_AUTO_DEALLOC to ISO_RES_AUTO_REALLOC. Prevent the back-transition by checking the current state before updating it in the work item. Fixes: fcabbf40fa ("firewire: core: move allocation/reallocation paths into specific branch after isoc resource management in cdev") Link: https://lore.kernel.org/r/20260922132639.191593-1-o-takashi@sakamocchi.jp Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp>		2026-09-23 09:20:17 +09:00
