Taehee Yoo says: ==================== amt: fix several bugs in amt_rcv() This series fixes bugs in amt_rcv(). First patch fixes pskb_may_pull() issue. Some functions missed to call pskb_may_pull() and uses wrong parameter of pskb_may_pull(). Second patch fixes possible null-ptr-deref in amt_rcv(). If there is no amt private data in sock, skb will be freed. And it increases stats. But in order to increase stats, amt private data is needed. So, uninitialised pointer will be used at that point. Third patch fixes wrong definition of type_str[] in amt.c ==================== Link: https://lore.kernel.org/r/20220602140108.18329-1-ap420073@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2022-06-06amt: fix wrong type string definitionTaehee Yoo

2022-06-06amt: fix possible null-ptr-deref in amt_rcv()Taehee Yoo
When amt interface receives amt message, it tries to obtain amt private data from sock. If there is no amt private data, it frees an skb immediately. After kfree_skb(), it increases the rx_dropped stats. But in order to use rx_dropped, amt private data is needed. So, it makes amt_rcv() to do not increase rx_dropped stats when it can not obtain amt private data.

2022-06-06drm/atomic: Force bridge self-refresh-exit on CRTC switchBrian Norris
It's possible to change which CRTC is in use for a given connector/encoder/bridge while we're in self-refresh without fully disabling the connector/encoder/bridge along the way. This can confuse the bridge encoder/bridge, because (a) it needs to track the SR state (trying to perform "active" operations while the panel is still in SR can be Bad(TM)); and (b) it tracks the SR state via the CRTC state (and after the switch, the previous SR state is lost). Thus, we need to either somehow carry the self-refresh state over to the new CRTC, or else force an encoder/bridge self-refresh transition during such a switch. I choose the latter, so we disable the encoder (and exit PSR) before attaching it to the new CRTC (where we can continue to assume a clean (non-self-refresh) state). This fixes PSR issues seen on Rockchip RK3399 systems with drivers/gpu/drm/bridge/analogix/analogix_dp_core.c. Change in v2: - Drop "->enable" condition; this could possibly be "->active" to reflect the intended hardware state, but it also is a little over-specific. We want to make a transition through "disabled" any time we're exiting PSR at the same time as a CRTC switch.

2022-06-06drm/bridge: analogix_dp: Support PSR-exit to disable transitionBrian Norris
Most eDP panel functions only work correctly when the panel is not in self-refresh. In particular, analogix_dp_bridge_disable() tends to hit AUX channel errors if the panel is in self-refresh. Given the above, it appears that so far, this driver assumes that we are never in self-refresh when it comes time to fully disable the bridge. Prior to commit 846c7dfc1193 ("drm/atomic: Try to preserve the crtc enabled state in drm_atomic_remove_fb, v2."), this tended to be true, because we would automatically disable the pipe when framebuffers were removed, and so we'd typically disable the bridge shortly after the last display activity. However, that is not guaranteed: an idle (self-refresh) display pipe may be disabled, e.g., when switching CRTCs. We need to exit PSR first. Stable notes: this is definitely a bugfix, and the bug has likely existed in some form for quite a while. It may predate the "PSR helpers" refactor, but the code looked very different before that, and it's probably not worth rewriting the fix.

2022-06-06net: phy: dp83867: retrigger SGMII AN when link changeTan Tee Min
There is a limitation in TI DP83867 PHY device where SGMII AN is only triggered once after the device is booted up. Even after the PHY TPI is down and up again, SGMII AN is not triggered and hence no new in-band message from PHY to MAC side SGMII. This could cause an issue during power up, when PHY is up prior to MAC. At this condition, once MAC side SGMII is up, MAC side SGMII wouldn`t receive new in-band message from TI PHY with correct link status, speed and duplex info. As suggested by TI, implemented a SW solution here to retrigger SGMII Auto-Neg whenever there is a link change. v2: Add Fixes tag in commit message.

2022-06-06ALSA: usb-audio: Set up (implicit) sync for Saffire 6Takashi Iwai
Focusrite Saffire 6 has fixed audioformat quirks with multiple endpoints assigned to a single altsetting. Unfortunately the generic parser couldn't detect the sync endpoint correctly as the implicit sync due to the missing EP attribute bits. In the former kernels, it used to work somehow casually, but it's been broken for a while after the large code change in 5.11. This patch cures the regression by the following: - Allow the static quirk table to provide the sync EP information; we just need to fill the fields and let the generic parser skipping parsing if sync_ep is already set. - Add the sync endpoint information to the entry for Saffire 6.

2022-06-06ALSA: usb-audio: Skip generic sync EP parse for secondary EPTakashi Iwai
When ep_idx is already non-zero, it means usually a capture stream that is set up explicity by a fixed-format quirk, and applying the check for generic (non-implicit-fb) sync EPs might hit incorrectly, resulting in a bogus sync endpoint for the capture stream. This patch adds a check for the ep_idx and skip if it's a secondary endpoint. It's a part of the fixes for regressions on Saffire 6.

To avoid the deferred probe timeout which takes place after reusing generic IOMMU device tree bindings (because the IOMMU device never becomes available) enable recently introduced stub IOMMU driver by selecting XEN_GRANT_DMA_IOMMU. Also introduce xen_is_grant_dma_device() to check whether xen-grant DMA ops need to be set for a passed device. Remove the hardcoded domid 0 in xen_grant_setup_dma_ops().

2022-06-06xen/grant-dma-iommu: Introduce stub IOMMU driverOleksandr Tyshchenko
In order to reuse generic IOMMU device tree bindings by Xen grant DMA-mapping layer we need to add this stub driver from a fw_devlink perspective (grant-dma-ops cannot be converted into the proper IOMMU driver). Otherwise, just reusing IOMMU bindings (without having a corresponding driver) leads to the deferred probe timeout afterwards, because the IOMMU device never becomes available. This stub driver does nothing except registering empty iommu_ops, the upper layer "of_iommu" will treat this as NO_IOMMU condition and won't return -EPROBE_DEFER. As this driver is quite different from the most hardware IOMMU implementations and only needed in Xen guests, place it in drivers/xen directory. The subsequent commit will make use of it.

2022-06-06dt-bindings: Add xen,grant-dma IOMMU description for xen-grant DMA opsOleksandr Tyshchenko
The main purpose of this binding is to communicate Xen specific information using generic IOMMU device tree bindings (which is a good fit here) rather than introducing a custom property. Introduce Xen specific IOMMU for the virtualized device (e.g. virtio) to be used by Xen grant DMA-mapping layer in the subsequent commit. The reference to Xen specific IOMMU node using "iommus" property indicates that Xen grant mappings need to be enabled for the device, and it specifies the ID of the domain where the corresponding backend resides. The domid (domain ID) is used as an argument to the Xen grant mapping APIs. This is needed for the option to restrict memory access using Xen grant mappings to work which primary goal is to enable using virtio devices in Xen guests.

As described in commit 02117b8ae9c0 ("f2fs: Set GF_NOFS in read_cache_page_gfp while doing f2fs_quota_read"), we must not enter filesystem reclaim while holding the dq_lock. Prevent this more generally by using memalloc_nofs_save() while holding the lock.

2022-06-06writeback: Fix inode->i_io_list not be protected by inode->i_lock errorJchao Sun
Commit b35250c0816c ("writeback: Protect inode->i_io_list with inode->i_lock") made inode->i_io_list not only protected by wb->list_lock but also inode->i_lock, but inode_io_list_move_locked() was missed. Add lock there and also update comment describing things protected by inode->i_lock. This also fixes a race where __mark_inode_dirty() could move inode under flush worker's hands and thus sync(2) could miss writing some inodes.

2022-06-06xen/grant-dma-ops: Add option to restrict memory access under XenJuergen Gross
Introduce Xen grant DMA-mapping layer which contains special DMA-mapping routines for providing grant references as DMA addresses to be used by frontends (e.g. virtio) in Xen guests. Add the needed functionality by providing a special set of DMA ops handling the needed grant operations for the I/O pages. The subsequent commit will introduce the use case for xen-grant DMA ops layer to enable using virtio devices in Xen guests in a safe manner.

2022-06-06xen/grants: support allocating consecutive grantsJuergen Gross
For support of virtio via grant mappings in rare cases larger mappings using consecutive grants are needed. Support those by adding a bitmap of free grants. As consecutive grants will be needed only in very rare cases (e.g. when configuring a virtio device with a multi-page ring), optimize for the normal case of non-consecutive allocations.
