Xiaolei Wang 3ee979709e remoteproc: core: Release rproc->clean_table after rproc_attach() fails ... commit bcd241230f upstream. When rproc->state = RPROC_DETACHED is attached to remote processor through rproc_attach(), if rproc_handle_resources() returns failure, then the clean table should be released, otherwise the following memory leak will occur. unreferenced object 0xffff000086a99800 (size 1024): comm "kworker/u12:3", pid 59, jiffies 4294893670 (age 121.140s) hex dump (first 32 bytes): 00 00 00 00 00 80 00 00 00 00 00 00 00 00 10 00 ............ 00 00 00 00 00 00 08 00 00 00 00 00 00 00 00 00 ............ backtrace: [<000000008bbe4ca8>] slab_post_alloc_hook+0x98/0x3fc [<000000003b8a272b>] __kmem_cache_alloc_node+0x13c/0x230 [<000000007a507c51>] __kmalloc_node_track_caller+0x5c/0x260 [<0000000037818dae>] kmemdup+0x34/0x60 [<00000000610f7f57>] rproc_boot+0x35c/0x56c [<0000000065f8871a>] rproc_add+0x124/0x17c [<00000000497416ee>] imx_rproc_probe+0x4ec/0x5d4 [<000000003bcaa37d>] platform_probe+0x68/0xd8 [<00000000771577f9>] really_probe+0x110/0x27c [<00000000531fea59>] __driver_probe_device+0x78/0x12c [<0000000080036a04>] driver_probe_device+0x3c/0x118 [<000000007e0bddcb>] __device_attach_driver+0xb8/0xf8 [<000000000cf1fa33>] bus_for_each_drv+0x84/0xe4 [<000000001a53b53e>] __device_attach+0xfc/0x18c [<00000000d1a2a32c>] device_initial_probe+0x14/0x20 [<00000000d8f8b7ae>] bus_probe_device+0xb0/0xb4 unreferenced object 0xffff0000864c9690 (size 16): Fixes: 9dc9507f18 ("remoteproc: Properly deal with the resource table when detaching") Signed-off-by: Xiaolei Wang <xiaolei.wang@windriver.com> Reviewed-by: Peng Fan <peng.fan@nxp.com> Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/20250430092043.1819308-3-xiaolei.wang@windriver.com Signed-off-by: Mathieu Poirier <mathieu.poirier@linaro.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2025-06-27 11:08:50 +01:00
