2023-03-07drm/i915: Get rid of the gm45 HPD live state nonsenseVille Syrjälä
The idea that ctg uses different HPD live state bits is total nonsense, at least on my machine (Dell Latitude E5400). The only reason DP-B even works on my ctg is that DP-D live state is stuck high, even though there is no physical DP-D port. So when the detect checks DP-B live state it sees the stuck live state of DP-D instead. If I hack the driver to not register DP-D at all, and thus we never enabe DP-D HPD, DP-B stops working as well. Just to put some conclusive evidence into this mess, here are the actual hotplug register values for each port: Everything disconnected: PORT_HOTPLUG_EN (0x00061110): 0x00000000 PORT_HOTPLUG_STAT (0x00061114): 0x00000000 PORT_HOTPLUG_EN (0x00061110): 0x08000000 PORT_HOTPLUG_STAT (0x00061114): 0x08000000 PORT_HOTPLUG_EN (0x00061110): 0x10000000 PORT_HOTPLUG_STAT (0x00061114): 0x00000000 PORT_HOTPLUG_EN (0x00061110): 0x20000000 PORT_HOTPLUG_STAT (0x00061114): 0x00000000 Only port B connected: PORT_HOTPLUG_EN (0x00061110): 0x00000000 PORT_HOTPLUG_STAT (0x00061114): 0x00000000 PORT_HOTPLUG_EN (0x00061110): 0x08000000 PORT_HOTPLUG_STAT (0x00061114): 0x08000000 PORT_HOTPLUG_EN (0x00061110): 0x10000000 PORT_HOTPLUG_STAT (0x00061114): 0x00000000 PORT_HOTPLUG_EN (0x00061110): 0x20000000 PORT_HOTPLUG_STAT (0x00061114): 0x20000000 Only port C connected: PORT_HOTPLUG_EN (0x00061110): 0x00000000 PORT_HOTPLUG_STAT (0x00061114): 0x00000000 PORT_HOTPLUG_EN (0x00061110): 0x08000000 PORT_HOTPLUG_STAT (0x00061114): 0x08000000 PORT_HOTPLUG_EN (0x00061110): 0x10000000 PORT_HOTPLUG_STAT (0x00061114): 0x10000000 PORT_HOTPLUG_EN (0x00061110): 0x20000000 PORT_HOTPLUG_STAT (0x00061114): 0x00000000 So the enable bit and live state bit always match 1:1.

2023-03-07platform/x86: dell-ddv: Fix temperature scalingArmin Wolf
After using the built-in UEFI hardware diagnostics to compare the measured battery temperature, i noticed that the temperature is actually expressed in tenth degree kelvin, similar to the SBS-Data standard. For example, a value of 2992 is displayed as 26 degrees celsius. Fix the scaling so that the correct values are being displayed. Tested on a Dell Inspiron 3505.

2023-03-07platform/x86: dell-ddv: Fix cache invalidation on resumeArmin Wolf
If one or both sensor buffers could not be initialized, either due to missing hardware support or due to some error during probing, the resume handler will encounter undefined behaviour when attempting to lock buffers then protected by an uninitialized or destroyed mutex. Fix this by introducing a "active" flag which is set during probe, and only invalidate buffers which where flaged as "active". Tested on a Dell Inspiron 3505.

2023-03-07netfilter: conntrack: adopt safer max chain lengthEric Dumazet
Customers using GKE 1.25 and 1.26 are facing conntrack issues root caused to commit c9c3b6811f74 ("netfilter: conntrack: make max chain length random"). Even if we assume Uniform Hashing, a bucket often reachs 8 chained items while the load factor of the hash table is smaller than 0.5 With a limit of 16, we reach load factors of 3. With a limit of 32, we reach load factors of 11. With a limit of 40, we reach load factors of 15. With a limit of 50, we reach load factors of 24. This patch changes MIN_CHAINLEN to 50, to minimize risks. Ideally, we could in the future add a cushion based on expected load factor (2 * nf_conntrack_max / nf_conntrack_buckets), because some setups might expect unusual values.

2023-03-06scsi: sd: Fix wrong zone_write_granularity value during revalidateShin'ichiro Kawasaki
When the sd driver revalidates host-managed SMR disks, it calls disk_set_zoned() which changes the zone_write_granularity attribute value to the logical block size regardless of the device type. After that, the sd driver overwrites the value in sd_zbc_read_zone() with the physical block size, since ZBC/ZAC requires this for host-managed disks. Between the calls to disk_set_zoned() and sd_zbc_read_zone(), there exists a window where the attribute shows the logical block size as the zone_write_granularity value, which is wrong for host-managed disks. The duration of the window is from 20ms to 200ms, depending on report zone command execution time. To avoid the wrong zone_write_granularity value between disk_set_zoned() and sd_zbc_read_zone(), modify the value not in sd_zbc_read_zone() but just after disk_set_zoned() call.

2023-03-06scsi: storvsc: Handle BlockSize change in Hyper-V VHD/VHDX fileMichael Kelley
Hyper-V uses a VHD or VHDX file on the host as the underlying storage for a virtual disk. The VHD/VHDX file format is a sparse format where real disk space on the host is assigned in chunks that the VHD/VHDX file format calls the BlockSize. This BlockSize is not to be confused with the 512-byte (or 4096-byte) sector size of the underlying storage device. The default block size for a new VHD/VHDX file is 32 Mbytes. When a guest VM touches any disk space within a 32 Mbyte chunk of the VHD/VHDX file, Hyper-V allocates 32 Mbytes of real disk space for that section of the VHD/VHDX. Similarly, if a discard operation is done that covers an entire 32 Mbyte chunk, Hyper-V will free the real disk space for that portion of the VHD/VHDX. This BlockSize is surfaced in Linux as the "discard_granularity" in /sys/block/sd<x>/queue, which makes sense. Hyper-V also has differencing disks that can overlay a VHD/VHDX file to capture changes to the VHD/VHDX while preserving the original VHD/VHDX. One example of this differencing functionality is for VM snapshots. When a snapshot is created, a differencing disk is created. If the snapshot is rolled back, Hyper-V can just delete the differencing disk, and the VM will see the original disk contents at the time the snapshot was taken. Differencing disks are used in other scenarios as well. The BlockSize for a differencing disk defaults to 2 Mbytes, not 32 Mbytes. The smaller default is used because changes to differencing disks are typically scattered all over, and Hyper-V doesn't want to allocate 32 Mbytes of real disk space for a stray write here or there. The smaller BlockSize provides more efficient use of real disk space. When a differencing disk is added to a VHD/VHDX, Hyper-V reports UNIT_ATTENTION with a sense code indicating "Operating parameters have changed", because the value of discard_granularity should be changed to 2 Mbytes. When the differencing disk is removed, discard_granularity should be changed back to 32 Mbytes. However, current code simply reports a message from scsi_report_sense() and the value of /sys/block/sd<x>/queue/discard_granularity is not updated. The message isn't very actionable by a sysadmin. Fix this by having the storvsc driver check for the sense code indicating that the underly VHD/VHDX block size has changed, and do a rescan of the device to pick up the new discard_granularity. With this change the entire transition to/from differencing disks is handled automatically and transparently, with no confusing messages being output.
