[Linux-stable-mirror] [git:media_tree/master] media: v4l2-compat-ioctl32.c: make ctrl_is_pointer work for subdevs

by Mauro Carvalho Chehab

This is an automatic generated email to let you know that the following patch were queued: Subject: media: v4l2-compat-ioctl32.c: make ctrl_is_pointer work for subdevs Author: Hans Verkuil <hansverk(a)cisco.com> Date: Tue Jan 30 10:18:32 2018 -0500 If the device is of type VFL_TYPE_SUBDEV then vdev->ioctl_ops is NULL so the 'if (!ops->vidioc_query_ext_ctrl)' check would crash. Add a test for !ops to the condition. All sub-devices that have controls will use the control framework, so they do not have an equivalent to ops->vidioc_query_ext_ctrl.

[Linux-stable-mirror] [PATCH] ibmvfc: fix misdefined reserved field in ibmvfc_fcp_rsp_info

by Tyrel Datwyler

The fcp_rsp_info structure as defined in the FC spec has an initial 3 bytes reserved field. The ibmvfc driver mistakenly defined this field as 4 bytes resulting in the rsp_code field being defined in what should be the start of the second reserved field and thus always being reported as zero by the driver. Ideally, we should wire ibmvfc up with libfc for the sake of code deduplication, and ease of maintaining standardized structures in a single place. However, for now simply fixup the definition in ibmvfc for backporting to distros on older kernels. Wiring up with libfc will be done in a followup patch.

[Linux-stable-mirror] [PATCH v3 2/5] crypto: caam: Fix endless loop when RNG is already initialized

by Bryan O'Donoghue

commit 1005bccd7a4a ("crypto: caam - enable instantiation of all RNG4 state handles") introduces a control when incrementing ent_delay which contains the following comment above it: /* * If either SH were instantiated by somebody else * (e.g. u-boot) then it is assumed that the entropy * parameters are properly set and thus the function * setting these (kick_trng(...)) is skipped. * Also, if a handle was instantiated, do not change * the TRNG parameters. */ This is a problem observed when sec_init() has been run in u-boot and and TrustZone is enabled. We can fix this by instantiating all rng state handles in u-boot but, on the Kernel side we should ensure that this non-terminating path is dealt with.

This commit has changed the way how the memory for memmaps is initialized and moves it from the allocation time to the initialization time. This works properly for the early memmap init path. It doesn't work for the memory hotplug though because we need to mark page as reserved when the sparsemem section is created and later initialize it completely during onlining. memmap_init_zone is called in the early stage of onlining. With the current code it calls __init_single_page and as such it clears up the whole stage and therefore online_pages_range skips those pages. Fix this by skipping mm_zero_struct_page in __init_single_page for memory hotplug path. This is quite uggly but unifying both early init and memory hotplug init paths is a large project. Make sure we plug the regression at least.

[Linux-stable-mirror] [PATCHv2 12/13] v4l2-compat-ioctl32.c: don't copy back the result for certain errors

[Linux-stable-mirror] [PATCHv2 09/13] v4l2-compat-ioctl32.c: fix ctrl_is_pointer

by Hans Verkuil

From: Hans Verkuil <hans.verkuil(a)cisco.com> ctrl_is_pointer just hardcoded two known string controls, but that caused problems when using e.g. custom controls that use a pointer for the payload. Reimplement this function: it now finds the v4l2_ctrl (if the driver uses the control framework) or it calls vidioc_query_ext_ctrl (if the driver implements that directly). In both cases it can now check if the control is a pointer control or not.
