[PATCH] RDMA/srp: Fix support for unpopulated and unbalanced NUMA nodes

by Yi Zhang

From: Nicolas Morey-Chaisemartin <nmoreychaisemartin(a)suse.com> This patch fixed one kernel NULL pointer issue with blktests srp/005 ---------- From: Nicolas Morey-Chaisemartin <nmoreychaisemartin(a)suse.com> commit 2b5715fc17386a6223490d5b8f08d031999b0c0b upstream. The current code computes a number of channels per SRP target and spreads them equally across all online NUMA nodes. Each channel is then assigned a CPU within this node. In the case of unbalanced, or even unpopulated nodes, some channels do not get a CPU associated and thus do not get connected. This causes the SRP connection to fail. This patch solves the issue by rewriting channel computation and allocation: - Drop channel to node/CPU association as it had no real effect on locality but added unnecessary complexity. - Tweak the number of channels allocated to reduce CPU contention when possible: - Up to one channel per CPU (instead of up to 4 by node) - At least 4 channels per node, unless ch_count module parameter is used.

Commit 78869f0f0552 ("arm64: Extract parts of el2_setup into a macro") reorganized el2 setup in such way that virtual cpu id registers set only in nVHE, yet they used (and need) to be set irrespective VHE support.

The root cause is, we have the following bad loop of creating tons of system chunks: 1. The only SYSTEM chunk is being scrubbed It's very common to have only one SYSTEM chunk. 2. New SYSTEM bg will be allocated As btrfs_inc_block_group_ro() will check if we have enough space after marking current bg RO. If not, then allocate a new chunk. 3. New SYSTEM bg is still empty, will be reclaimed During the reclaim, we will mark it RO again. 4. That newly allocated empty SYSTEM bg get scrubbed We go back to step 2, as the bg is already mark RO but still not cleaned up yet. If the cleaner kthread doesn't get executed fast enough (e.g. only one CPU), then we will get more and more empty SYSTEM chunks, using up all the space of btrfs_super_block::sys_chunk_array. [FIX] Since scrub/dev-replace doesn't always need to allocate new extent, especially chunk tree extent, so we don't really need to do chunk pre-allocation. To break above spiral, here we introduce a new parameter to btrfs_inc_block_group(), @do_chunk_alloc, which indicates whether we need extra chunk pre-allocation. For relocation, we pass @do_chunk_alloc=true, while for scrub, we pass @do_chunk_alloc=false. This should keep unnecessary empty chunks from popping up for scrub.

[PATCH v7 01/17] media: v4l2-ioctl: Fix check_ext_ctrls

by Ricardo Ribalda

Drivers that do not use the ctrl-framework use this function instead. Fix the following issues: - Do not check for multiple classes when getting the DEF_VAL. - Return -EINVAL for request_api calls - Default value cannot be changed, return EINVAL as soon as possible. - Return the right error_idx [If an error is found when validating the list of controls passed with VIDIOC_G_EXT_CTRLS, then error_idx shall be set to ctrls->count to indicate to userspace that no actual hardware was touched. It would have been much nicer of course if error_idx could point to the control index that failed the validation, but sadly that's not how the API was designed.] Fixes v4l2-compliance: Control ioctls (Input 0): warn: v4l2-test-controls.cpp(834): error_idx should be equal to count warn: v4l2-test-controls.cpp(855): error_idx should be equal to count fail: v4l2-test-controls.cpp(813): doioctl(node, VIDIOC_G_EXT_CTRLS, &ctrls) test VIDIOC_G/S/TRY_EXT_CTRLS: FAIL Buffer ioctls (Input 0): fail: v4l2-test-buffers.cpp(1994): ret != EINVAL && ret != EBADR && ret != ENOTTY test Requests: FAIL Cc: stable(a)vger.kernel.org Fixes: 6fa6f831f095 ("media: v4l2-ctrls: add core request support") Suggested-by: Hans Verkuil <hverkuil-cisco(a)xs4all.nl> Reviewed-by: Hans Verkuil <hverkuil-cisco(a)xs4all.nl> Signed-off-by: Ricardo Ribalda <ribalda(a)chromium.org> --- drivers/media/v4l2-core/v4l2-ioctl.c | 59 ++++++++++++++++++---------- 1 file changed, 38 insertions(+), 21 deletions(-) diff --git a/drivers/media/v4l2-core/v4l2-ioctl.c b/drivers/media/v4l2-core/v4l2-ioctl.c index 31d1342e61e8..ccd21b4d9c72 100644 --- a/drivers/media/v4l2-core/v4l2-ioctl.c +++ b/drivers/media/v4l2-core/v4l2-ioctl.c @@ -908,7 +908,7 @@ static void v4l_print_default(const void *arg, bool write_only) pr_cont("driver-specific ioctl\n"); } -static int check_ext_ctrls(struct v4l2_ext_controls *c, int allow_priv) +static bool check_ext_ctrls(struct v4l2_ext_controls *c, unsigned long ioctl) { __u32 i; @@ -917,23 +917,40 @@ static int check_ext_ctrls(struct v4l2_ext_controls *c, int allow_priv) for (i = 0; i < c->count; i++) c->controls[i].reserved2[0] = 0; - /* V4L2_CID_PRIVATE_BASE cannot be used as control class - when using extended controls. - Only when passed in through VIDIOC_G_CTRL and VIDIOC_S_CTRL - is it allowed for backwards compatibility. - */ - if (!allow_priv && c->which == V4L2_CID_PRIVATE_BASE) - return 0; - if (!c->which) - return 1; + switch (c->which) { + case V4L2_CID_PRIVATE_BASE: + /* + * V4L2_CID_PRIVATE_BASE cannot be used as control class + * when using extended controls. + * Only when passed in through VIDIOC_G_CTRL and VIDIOC_S_CTRL + * is it allowed for backwards compatibility. + */ + if (ioctl == VIDIOC_G_CTRL || ioctl == VIDIOC_S_CROP) + return false; + break; + case V4L2_CTRL_WHICH_DEF_VAL: + /* Default value cannot be changed */ + if (ioctl == VIDIOC_S_EXT_CTRLS || + ioctl == VIDIOC_TRY_EXT_CTRLS) { + c->error_idx = c->count; + return false; + } + return true; + case V4L2_CTRL_WHICH_CUR_VAL: + return true; + case V4L2_CTRL_WHICH_REQUEST_VAL: + c->error_idx = c->count; + return false; + } + /* Check that all controls are from the same control class. */ for (i = 0; i < c->count; i++) { if (V4L2_CTRL_ID2WHICH(c->controls[i].id) != c->which) { - c->error_idx = i; - return 0; + c->error_idx = ioctl == VIDIOC_TRY_EXT_CTRLS ? i : c->count; + return false; } } - return 1; + return true; } static int check_fmt(struct file *file, enum v4l2_buf_type type) @@ -2229,7 +2246,7 @@ static int v4l_g_ctrl(const struct v4l2_ioctl_ops *ops, ctrls.controls = &ctrl; ctrl.id = p->id; ctrl.value = p->value; - if (check_ext_ctrls(&ctrls, 1)) { + if (check_ext_ctrls(&ctrls, VIDIOC_G_CTRL)) { int ret = ops->vidioc_g_ext_ctrls(file, fh, &ctrls); if (ret == 0) @@ -2263,7 +2280,7 @@ static int v4l_s_ctrl(const struct v4l2_ioctl_ops *ops, ctrls.controls = &ctrl; ctrl.id = p->id; ctrl.value = p->value; - if (check_ext_ctrls(&ctrls, 1)) + if (check_ext_ctrls(&ctrls, VIDIOC_S_CTRL)) return ops->vidioc_s_ext_ctrls(file, fh, &ctrls); return -EINVAL; } @@ -2285,8 +2302,8 @@ static int v4l_g_ext_ctrls(const struct v4l2_ioctl_ops *ops, vfd, vfd->v4l2_dev->mdev, p); if (ops->vidioc_g_ext_ctrls == NULL) return -ENOTTY; - return check_ext_ctrls(p, 0) ? ops->vidioc_g_ext_ctrls(file, fh, p) : - -EINVAL; + return check_ext_ctrls(p, VIDIOC_G_EXT_CTRLS) ? + ops->vidioc_g_ext_ctrls(file, fh, p) : -EINVAL; } static int v4l_s_ext_ctrls(const struct v4l2_ioctl_ops *ops, @@ -2306,8 +2323,8 @@ static int v4l_s_ext_ctrls(const struct v4l2_ioctl_ops *ops, vfd, vfd->v4l2_dev->mdev, p); if (ops->vidioc_s_ext_ctrls == NULL) return -ENOTTY; - return check_ext_ctrls(p, 0) ? ops->vidioc_s_ext_ctrls(file, fh, p) : - -EINVAL; + return check_ext_ctrls(p, VIDIOC_S_EXT_CTRLS) ? + ops->vidioc_s_ext_ctrls(file, fh, p) : -EINVAL; } static int v4l_try_ext_ctrls(const struct v4l2_ioctl_ops *ops, @@ -2327,8 +2344,8 @@ static int v4l_try_ext_ctrls(const struct v4l2_ioctl_ops *ops, vfd, vfd->v4l2_dev->mdev, p); if (ops->vidioc_try_ext_ctrls == NULL) return -ENOTTY; - return check_ext_ctrls(p, 0) ? ops->vidioc_try_ext_ctrls(file, fh, p) : - -EINVAL; + return check_ext_ctrls(p, VIDIOC_TRY_EXT_CTRLS) ? + ops->vidioc_try_ext_ctrls(file, fh, p) : -EINVAL; } /* -- 2.31.0.rc2.261.g7f71774620-goog

[PATCH v4 0/1] s390/vfio-ap: fix circular lockdep when starting

by Tony Krowiak

*Commit f21916ec4826 ("s390/vfio-ap: clean up vfio_ap resources when KVM pointer invalidated") introduced a change that results in a circular lockdep when a Secure Execution guest that is configured with crypto devices is started. The problem resulted due to the fact that the patch moved the setting of the guest's AP masks within the protection of the matrix_dev->lock when the vfio_ap driver is notified that the KVM pointer has been set. Since it is not critical that setting/clearing of the guest's AP masks be done under the matrix_dev->lock when the driver is notified, the masks will not be updated under the matrix_dev->lock. The lock is necessary for the setting/unsetting of the KVM pointer, however, so that will remain in place. The dependency chain for the circular lockdep resolved by this patch is (in reverse order): 2: vfio_ap_mdev_group_notifier: kvm->lock matrix_dev->lock 1: handle_pqap: matrix_dev->lock kvm_vcpu_ioctl: vcpu->mutex 0: kvm_s390_cpus_to_pv: vcpu->mutex kvm_vm_ioctl: kvm->lock Please note: ----------- * If checkpatch is run against this patch series, you may get a "WARNING: Unknown commit id 'f21916ec4826', maybe rebased or not pulled?" message. The commit 'f21916ec4826', however, is definitely in the master branch on top of which this patch series was built, so I'm not sure why this message is being output by checkpatch. * All acks granted from previous review of this patch have been removed due to the fact that this patch introduces non-trivial changes (see change log below). Change log v3=> v4: ------------------ * In vfio_ap_mdev_set_kvm() function, moved the setting of matrix_mdev->kvm_busy just prior to unlocking matrix_dev->lock. * Reset queues regardless of regardless of the value of matrix_mdev->kvm in response to the VFIO_DEVICE_RESET ioctl. Change log v2=> v3: ------------------ * Added two fields - 'bool kvm_busy' and 'wait_queue_head_t wait_for_kvm' to struct ap_matrix_mdev. The former indicates that the KVM pointer is in the process of being updated and the second allows a function that needs access to the KVM pointer to wait until it is no longer being updated. Resolves problem of synchronization between the functions that change the KVM pointer value and the functions that required access to it. Change log v1=> v2: ------------------ * No longer holding the matrix_dev->lock prior to setting/clearing the masks supplying the AP configuration to a KVM guest. * Make all updates to the data in the matrix mdev that is used to manage AP resources used by the KVM guest in the vfio_ap_mdev_set_kvm() function instead of the group notifier callback. * Check for the matrix mdev's KVM pointer in the vfio_ap_mdev_unset_kvm() function instead of the vfio_ap_mdev_release() function.

[PATCH net] netsec: restore phy power state after controller reset

by Mian Yousaf Kaukab

Since commit 8e850f25b581 ("net: socionext: Stop PHY before resetting netsec") netsec_netdev_init() power downs phy before resetting the controller. However, the state is not restored once the reset is complete. As a result it is not possible to bring up network on a platform with Broadcom BCM5482 phy. Fix the issue by restoring phy power state after controller reset is complete.
