2023-01-22drm/msm/dsi: implement opp table based check for dsi_mgr_bridge_mode_valid()Abhinav Kumar
Currently there is no protection against a user trying to set an unsupported mode on DSI. Implement a check based on the opp table whether the byte clock for the mode can be supported by validating whether an opp table entry exists. For devices which have not added opp table support yet, skip this check otherwise it will break bootup on those devices. changes in v3: - make the comment shorter - handle all errors except ENODEV Closes: https://gitlab.freedesktop.org/drm/msm/-/issues/15 Reported-by: Rob Clark <robdclark@gmail.com> Signed-off-by: Abhinav Kumar <quic_abhinavk@quicinc.com> Reviewed-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Patchwork: https://patchwork.freedesktop.org/patch/518008/ Link: https://lore.kernel.org/r/20230112001600.12791-2-quic_abhinavk@quicinc.com Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>

2023-01-22KVM: x86/vmx: Do not skip segment attributes if unusable bit is setHendrik Borghorst
When serializing and deserializing kvm_sregs, attributes of the segment descriptors are stored by user space. For unusable segments, vmx_segment_access_rights skips all attributes and sets them to 0. This means we zero out the DPL (Descriptor Privilege Level) for unusable entries. Unusable segments are - contrary to their name - usable in 64bit mode and are used by guests to for example create a linear map through the NULL selector. VMENTER checks if SS.DPL is correct depending on the CS segment type. For types 9 (Execute Only) and 11 (Execute Read), CS.DPL must be equal to SS.DPL [1]. We have seen real world guests setting CS to a usable segment with DPL=3 and SS to an unusable segment with DPL=3. Once we go through an sregs get/set cycle, SS.DPL turns to 0. This causes the virtual machine to crash reproducibly. This commit changes the attribute logic to always preserve attributes for unusable segments. According to [2] SS.DPL is always saved on VM exits, regardless of the unusable bit so user space applications should have saved the information on serialization correctly. [3] specifies that besides SS.DPL the rest of the attributes of the descriptors are undefined after VM entry if unusable bit is set. So, there should be no harm in setting them all to the previous state.

2023-01-22Revert "gfs2: stop using generic_writepages in gfs2_ail1_start_one"Andreas Gruenbacher
Commit b2b0a5e97855 switched from generic_writepages() to filemap_fdatawrite_wbc() in gfs2_ail1_start_one() on the path to replacing ->writepage() with ->writepages() and eventually eliminating the former. Function gfs2_ail1_start_one() is called from gfs2_log_flush(), our main function for flushing the filesystem log. Unfortunately, at least as implemented today, ->writepage() and ->writepages() are entirely different operations for journaled data inodes: while the former creates and submits transactions covering the data to be written, the latter flushes dirty buffers out to disk. With gfs2_ail1_start_one() now calling ->writepages(), we end up creating filesystem transactions while we are in the course of a log flush, which immediately deadlocks on the sdp->sd_log_flush_lock semaphore. Work around that by going back to how things used to work before commit b2b0a5e97855 for now; figuring out a superior solution will take time we don't have available right now. However ... Since the removal of generic_writepages() is imminent, open-code it here. We're already inside a blk_start_plug() ... blk_finish_plug() section here, so skip that part of the original generic_writepages(). This reverts commit b2b0a5e978552e348f85ad9c7568b630a5ede659.

2023-01-21ext4: deal with legacy signed xattr name hash valuesLinus Torvalds
We potentially have old hashes of the xattr names generated on systems with signed 'char' types. Now that everybody uses '-funsigned-char', those hashes will no longer match. This only happens if you use xattrs names that have the high bit set, which probably doesn't happen in practice, but the xfstest generic/454 shows it. Instead of adding a new "signed xattr hash filesystem" bit and having to deal with all the possible combinations, just calculate the hash both ways if the first one fails, and always generate new hashes with the proper unsigned char version.

2023-01-21KVM: arm64: GICv4.1: Fix race with doorbell on VPE activation/deactivationMarc Zyngier
To save the vgic LPI pending state with GICv4.1, the VPEs must all be unmapped from the ITSs so that the sGIC caches can be flushed. The opposite is done once the state is saved. This is all done by using the activate/deactivate irqdomain callbacks directly from the vgic code. Crutially, this is done without holding the irqdesc lock for the interrupts that represent the VPE. And these callbacks are changing the state of the irqdesc. What could possibly go wrong? If a doorbell fires while we are messing with the irqdesc state, it will acquire the lock and change the interrupt state concurrently. Since we don't hole the lock, curruption occurs in on the interrupt state. Oh well. While acquiring the lock would fix this (and this was Shanker's initial approach), this is still a layering violation we could do without. A better approach is actually to free the VPE interrupt, do what we have to do, and re-request it. It is more work, but this usually happens only once in the lifetime of the VM and we don't really care about this sort of overhead.
