userspace When calling the KVM_GET_DEBUGREGS ioctl, on some configurations, there might be some unitialized portions of the kvm_debugregs structure that could be copied to userspace. Prevent this as is done in the other kvm ioctls, by setting the whole structure to 0 before copying anything into it. Bonus is that this reduces the lines of code as the explicit flag setting and reserved space zeroing out can be removed.

2023-02-16ASoC: SOF: Intel: hda-dai: fix possible stream_tag leakPierre-Louis Bossart
The HDaudio stream allocation is done first, and in a second step the LOSIDV parameter is programmed for the multi-link used by a codec. This leads to a possible stream_tag leak, e.g. if a DisplayAudio link is not used. This would happen when a non-Intel graphics card is used and userspace unconditionally uses the Intel Display Audio PCMs without checking if they are connected to a receiver with jack controls. We should first check that there is a valid multi-link entry to configure before allocating a stream_tag. This change aligns the dma_assign and dma_cleanup phases.

2023-02-16devlink: Fix netdev notifier chain corruptionIdo Schimmel
Cited commit changed devlink to register its netdev notifier block on the global netdev notifier chain instead of on the per network namespace one. However, when changing the network namespace of the devlink instance, devlink still tries to unregister its notifier block from the chain of the old namespace and register it on the chain of the new namespace. This results in corruption of the notifier chains, as the same notifier block is registered on two different chains: The global one and the per network namespace one. In turn, this causes other problems such as the inability to dismantle namespaces due to netdev reference count issues. Fix by preventing devlink from moving its notifier block between namespaces. Reproducer: # echo "10 1" > /sys/bus/netdevsim/new_device # ip netns add test123 # devlink dev reload netdevsim/netdevsim10 netns test123 # ip netns del test123 [ 71.935619] unregister_netdevice: waiting for lo to become free.

2023-02-15igb: conditionalize I2C bit banging on external thermal sensor supportCorinna Vinschen
Commit a97f8783a937 ("igb: unbreak I2C bit-banging on i350") introduced code to change I2C settings to bit banging unconditionally. However, this patch introduced a regression: On an Intel S2600CWR Server Board with three NICs: - 1x dual-port copper Intel I350 Gigabit Network Connection [8086:1521] (rev 01) fw 1.63, 0x80000dda - 2x quad-port SFP+ with copper SFP Avago ABCU-5700RZ Intel I350 Gigabit Fiber Network Connection [8086:1522] (rev 01) fw 1.52.0 the SFP NICs no longer get link at all. Reverting commit a97f8783a937 or switching to the Intel out-of-tree driver both fix the problem. Per the igb out-of-tree driver, I2C bit banging on i350 depends on support for an external thermal sensor (ETS). However, commit a97f8783a937 added bit banging unconditionally. Additionally, the out-of-tree driver always calls init_thermal_sensor_thresh on probe, while our driver only calls init_thermal_sensor_thresh only in igb_reset(), and only if an ETS is present, ignoring the internal thermal sensor. The affected SFPs don't provide an ETS. Per Intel, the behaviour is a result of i350 firmware requirements. This patch fixes the problem by aligning the behaviour to the out-of-tree driver: - split igb_init_i2c() into two functions: - igb_init_i2c() only performs the basic I2C initialization. - igb_set_i2c_bb() makes sure that E1000_CTRL_I2C_ENA is set and enables bit-banging. - igb_probe() only calls igb_set_i2c_bb() if an ETS is present. - igb_probe() calls init_thermal_sensor_thresh() unconditionally. - igb_reset() aligns its behaviour to igb_probe(), i. e., call igb_set_i2c_bb() if an ETS is present and call init_thermal_sensor_thresh() unconditionally.

2023-02-15apparmor: Fix regression in compat permissions for getattrJohn Johansen
This fixes a regression in mediation of getattr when old policy built under an older ABI is loaded and mapped to internal permissions. The regression does not occur for all getattr permission requests, only appearing if state zero is the final state in the permission lookup. This is because despite the first state (index 0) being guaranteed to not have permissions in both newer and older permission formats, it may have to carry permissions that were not mediated as part of an older policy. These backward compat permissions are mapped here to avoid special casing the mediation code paths. Since the mapping code already takes into account backwards compat permission from older formats it can be applied to state 0 to fix the regression.

2023-02-15btrfs: don't rely on unchanging ->bi_bdev for zone append remapsChristoph Hellwig
btrfs_record_physical_zoned relies on a bio->bi_bdev samples in the bio_end_io handler to find the reverse map for remapping the zone append write, but stacked block device drivers can and usually do change bi_bdev when sending on the bio to a lower device. This can happen e.g. with the nvme-multipath driver when a NVMe SSD sets the shared namespace bit. But there is no real need for the bdev in btrfs_record_physical_zoned, as it is only passed to btrfs_rmap_block, which uses it to pick the mapping to report if there are multiple reverse mappings. As zone writes can only do simple non-mirror writes right now, and anything more complex will use the stripe tree there is no chance of the multiple mappings case actually happening. Instead open code the subset of btrfs_rmap_block in btrfs_record_physical_zoned, which also removes a memory allocation and remove the bdev field in the ordered extent.

2023-02-15btrfs: do unsigned integer division in the extent buffer binary search loopFilipe Manana
In the search loop of the binary search function, we are doing a division by 2 of the sum of the high and low slots. Because the slots are integers, the generated assembly code for it is the following on x86_64: 0x00000000000141f1 <+145>: mov %eax,%ebx 0x00000000000141f3 <+147>: shr $0x1f,%ebx 0x00000000000141f6 <+150>: add %eax,%ebx 0x00000000000141f8 <+152>: sar %ebx It's a few more instructions than a simple right shift, because signed integer division needs to round towards zero. However we know that slots can never be negative (btrfs_header_nritems() returns an u32), so we can instead use unsigned types for the low and high slots and therefore use unsigned integer division, which results in a single instruction on x86_64: 0x00000000000141f0 <+144>: shr %ebx So use unsigned types for the slots and therefore unsigned division. This is part of a small patchset comprised of the following two patches: btrfs: eliminate extra call when doing binary search on extent buffer btrfs: do unsigned integer division in the extent buffer binary search loop The following fs_mark test was run on a non-debug kernel (Debian's default kernel config) before and after applying the patchset: $ cat test.sh #!/bin/bash DEV=/dev/sdi MNT=/mnt/sdi MOUNT_OPTIONS="-o ssd" MKFS_OPTIONS="-O no-holes -R free-space-tree" FILES=100000 THREADS=$(nproc --all) FILE_SIZE=0 umount $DEV &> /dev/null mkfs.btrfs -f $MKFS_OPTIONS $DEV mount $MOUNT_OPTIONS $DEV $MNT OPTS="-S 0 -L 6 -n $FILES -s $FILE_SIZE -t $THREADS -k" for ((i = 1; i <= $THREADS; i++)); do OPTS="$OPTS -d $MNT/d$i" done fs_mark $OPTS umount $MNT Results before applying patchset: FSUse% Count Size Files/sec App Overhead 2 1200000 0 174472.0 11549868 4 2400000 0 253503.0 11694618 4 3600000 0 257833.1 11611508 6 4800000 0 247089.5 11665983 6 6000000 0 211296.1 12121244 10 7200000 0 187330.6 12548565 Results after applying patchset: FSUse% Count Size Files/sec App Overhead 2 1200000 0 207556.0 11393252 4 2400000 0 266751.1 11347909 4 3600000 0 274397.5 11270058 6 4800000 0 259608.4 11442250 6 6000000 0 238895.8 11635921 8 7200000 0 211942.2 11873825 Reviewed-by: Josef Bacik <josef@toxicpanda.com> Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: David Sterba <dsterba@suse.com> Signed-off-by: David Sterba <dsterba@suse.com>

2023-02-15btrfs: replace clearing extent buffer dirty bit with btrfs_clean_blockJosef Bacik
Now that we're passing in the trans into btrfs_clean_tree_block, we can easily roll in the handling of the !trans case and replace all occurrences of if (test_and_clear_bit(EXTENT_BUFFER_DIRTY, &eb->bflags)) clear_extent_buffer_dirty(eb); with btrfs_tree_lock(eb); btrfs_clean_tree_block(eb); btrfs_tree_unlock(eb); We need the lock because if we are actually dirty we need to make sure we aren't racing with anything that's starting writeout currently.

2023-02-15btrfs: add trans argument to btrfs_clean_tree_blockJosef Bacik
We check the header generation in the extent buffer against the current running transaction id to see if it's safe to clear DIRTY on this buffer. Generally speaking if we're clearing the buffer dirty we're holding the transaction open, but in the case of cleaning up an aborted transaction we don't, so we have extra checks in that path to check the transid. To allow for a future cleanup go ahead and pass in the trans handle so we don't have to rely on ->running_transaction being set.

2023-02-15btrfs: split zone append bios in btrfs_submit_bioChristoph Hellwig
The current btrfs zoned device support is a little cumbersome in the data I/O path as it requires the callers to not issue I/O larger than the supported ZONE_APPEND size of the underlying device. This leads to a lot of extra accounting. Instead change btrfs_submit_bio so that it can take write bios of arbitrary size and form from the upper layers, and just split them internally to the ZONE_APPEND queue limits. Then remove all the upper layer warts catering to limited write sized on zoned devices, including the extra refcount in the compressed_bio.
