[PATCH OLK-6.6] media: imx-jpeg: Ensure power suppliers be suspended before detach them
by Li Huafei 30 Dec '24

30 Dec '24

From: Ming Qian <ming.qian(a)nxp.com> stable inclusion from stable-v6.6.64 commit b7a830bbc25da0f641e3ef2bac3b1766b2777a8b category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEANC CVE: CVE-2024-56575 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit fd0af4cd35da0eb550ef682b71cda70a4e36f6b9 upstream. The power suppliers are always requested to suspend asynchronously, dev_pm_domain_detach() requires the caller to ensure proper synchronization of this function with power management callbacks. otherwise the detach may led to kernel panic, like below: [ 1457.107934] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000040 [ 1457.116777] Mem abort info: [ 1457.119589] ESR = 0x0000000096000004 [ 1457.123358] EC = 0x25: DABT (current EL), IL = 32 bits [ 1457.128692] SET = 0, FnV = 0 [ 1457.131764] EA = 0, S1PTW = 0 [ 1457.134920] FSC = 0x04: level 0 translation fault [ 1457.139812] Data abort info: [ 1457.142707] ISV = 0, ISS = 0x00000004, ISS2 = 0x00000000 [ 1457.148196] CM = 0, WnR = 0, TnD = 0, TagAccess = 0 [ 1457.153256] GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0 [ 1457.158563] user pgtable: 4k pages, 48-bit VAs, pgdp=00000001138b6000 [ 1457.165000] [0000000000000040] pgd=0000000000000000, p4d=0000000000000000 [ 1457.171792] Internal error: Oops: 0000000096000004 [#1] PREEMPT SMP [ 1457.178045] Modules linked in: v4l2_jpeg wave6_vpu_ctrl(-) [last unloaded: mxc_jpeg_encdec] [ 1457.186383] CPU: 0 PID: 51938 Comm: kworker/0:3 Not tainted 6.6.36-gd23d64eea511 #66 [ 1457.194112] Hardware name: NXP i.MX95 19X19 board (DT) [ 1457.199236] Workqueue: pm pm_runtime_work [ 1457.203247] pstate: 60400009 (nZCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 1457.210188] pc : genpd_runtime_suspend+0x20/0x290 [ 1457.214886] lr : __rpm_callback+0x48/0x1d8 [ 1457.218968] sp : ffff80008250bc50 [ 1457.222270] x29: ffff80008250bc50 x28: 0000000000000000 x27: 0000000000000000 [ 1457.229394] x26: 0000000000000000 x25: 0000000000000008 x24: 00000000000f4240 [ 1457.236518] x23: 0000000000000000 x22: ffff00008590f0e4 x21: 0000000000000008 [ 1457.243642] x20: ffff80008099c434 x19: ffff00008590f000 x18: ffffffffffffffff [ 1457.250766] x17: 5300326563697665 x16: 645f676e696c6f6f x15: 63343a6d726f6674 [ 1457.257890] x14: 0000000000000004 x13: 00000000000003a4 x12: 0000000000000002 [ 1457.265014] x11: 0000000000000000 x10: 0000000000000a60 x9 : ffff80008250bbb0 [ 1457.272138] x8 : ffff000092937200 x7 : ffff0003fdf6af80 x6 : 0000000000000000 [ 1457.279262] x5 : 00000000410fd050 x4 : 0000000000200000 x3 : 0000000000000000 [ 1457.286386] x2 : 0000000000000000 x1 : 0000000000000000 x0 : ffff00008590f000 [ 1457.293510] Call trace: [ 1457.295946] genpd_runtime_suspend+0x20/0x290 [ 1457.300296] __rpm_callback+0x48/0x1d8 [ 1457.304038] rpm_callback+0x6c/0x78 [ 1457.307515] rpm_suspend+0x10c/0x570 [ 1457.311077] pm_runtime_work+0xc4/0xc8 [ 1457.314813] process_one_work+0x138/0x248 [ 1457.318816] worker_thread+0x320/0x438 [ 1457.322552] kthread+0x110/0x114 [ 1457.325767] ret_from_fork+0x10/0x20 Fixes: 2db16c6ed72c ("media: imx-jpeg: Add V4L2 driver for i.MX8 JPEG Encoder/Decoder") Cc: <stable(a)vger.kernel.org> Signed-off-by: Ming Qian <ming.qian(a)nxp.com> Reviewed-by: TaoJiang <tao.jiang_2(a)nxp.com> Signed-off-by: Hans Verkuil <hverkuil-cisco(a)xs4all.nl> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Signed-off-by: Li Huafei <lihuafei1(a)huawei.com> --- drivers/media/platform/nxp/imx-jpeg/mxc-jpeg.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/media/platform/nxp/imx-jpeg/mxc-jpeg.c b/drivers/media/platform/nxp/imx-jpeg/mxc-jpeg.c index 2007152cd7a4..f6fcee52d138 100644 --- a/drivers/media/platform/nxp/imx-jpeg/mxc-jpeg.c +++ b/drivers/media/platform/nxp/imx-jpeg/mxc-jpeg.c @@ -2674,6 +2674,8 @@ static void mxc_jpeg_detach_pm_domains(struct mxc_jpeg_dev *jpeg) int i; for (i = 0; i < jpeg->num_domains; i++) { + if (jpeg->pd_dev[i] && !pm_runtime_suspended(jpeg->pd_dev[i])) + pm_runtime_force_suspend(jpeg->pd_dev[i]); if (jpeg->pd_link[i] && !IS_ERR(jpeg->pd_link[i])) device_link_del(jpeg->pd_link[i]); if (jpeg->pd_dev[i] && !IS_ERR(jpeg->pd_dev[i])) -- 2.25.1
