2023-02-17arm64: perf: reject CHAIN events at creation timeMark Rutland1-0/+8
Currently it's possible for a user to open CHAIN events arbitrarily, which we previously tried to rule out in commit: ca2b497253ad01c8 ("arm64: perf: Reject stand-alone CHAIN events for PMUv3") Which allowed the events to be opened, but prevented them from being scheduled by by using an arm_pmu::filter_match hook to reject the relevant events. The CHAIN event filtering in the arm_pmu::filter_match hook was silently removed in commit: bd27568117664b8b ("perf: Rewrite core context handling") As a result, it's now possible for users to open CHAIN events, and for these to be installed arbitrarily. Fix this by rejecting CHAIN events at creation time. This avoids the creation of events which will never count, and doesn't require using the dynamic filtering. Attempting to open a CHAIN event (0x1e) will now be rejected: | # ./perf stat -e armv8_pmuv3/config=0x1e/ ls | perf | | Performance counter stats for 'ls': | | <not supported> armv8_pmuv3/config=0x1e/ | | 0.002197470 seconds time elapsed | | 0.000000000 seconds user | 0.002294000 seconds sys Other events (e.g. CPU_CYCLES / 0x11) will open as usual: | # ./perf stat -e armv8_pmuv3/config=0x11/ ls | perf | | Performance counter stats for 'ls': | | 2538761 armv8_pmuv3/config=0x11/ | | 0.002227330 seconds time elapsed | | 0.002369000 seconds user | 0.000000000 seconds sys Fixes: bd2756811766 ("perf: Rewrite core context handling") Signed-off-by: Mark Rutland <mark.rutland@arm.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Ravi Bangoria <ravi.bangoria@amd.com> Cc: Will Deacon <will@kernel.org> Link: https://lore.kernel.org/r/20230216141240.3833272-3-mark.rutland@arm.com Signed-off-by: Will Deacon <will@kernel.org>
2023-02-17arm_pmu: fix event CPU filteringMark Rutland3-15/+1
Janne reports that perf has been broken on Apple M1 as of commit: bd27568117664b8b ("perf: Rewrite core context handling") That commit replaced the pmu::filter_match() callback with pmu::filter(), whose return value has the opposite polarity, with true implying events should be ignored rather than scheduled. While an attempt was made to update the logic in armv8pmu_filter() and armpmu_filter() accordingly, the return value remains inverted in a couple of cases: * If the arm_pmu does not have an arm_pmu::filter() callback, armpmu_filter() will always return whether the CPU is supported rather than whether the CPU is not supported. As a result, the perf core will not schedule events on supported CPUs, resulting in a loss of events. Additionally, the perf core will attempt to schedule events on unsupported CPUs, but this will be rejected by armpmu_add(), which may result in a loss of events from other PMUs on those unsupported CPUs. * If the arm_pmu does have an arm_pmu::filter() callback, and armpmu_filter() is called on a CPU which is not supported by the arm_pmu, armpmu_filter() will return false rather than true. As a result, the perf core will attempt to schedule events on unsupported CPUs, but this will be rejected by armpmu_add(), which may result in a loss of events from other PMUs on those unsupported CPUs. This means a loss of events can be seen with any arm_pmu driver, but with the ARMv8 PMUv3 driver (which is the only arm_pmu driver with an arm_pmu::filter() callback) the event loss will be more limited and may go unnoticed, which is how this issue evaded testing so far. Fix the CPU filtering by performing this consistently in armpmu_filter(), and remove the redundant arm_pmu::filter() callback and armv8pmu_filter() implementation. Commit bd2756811766 also silently removed the CHAIN event filtering from armv8pmu_filter(), which will be addressed by a separate patch without using the filter callback.

2023-02-16brd: mark as nowait compatibleJens Axboe1-0/+1
By default, non-mq drivers do not support nowait. This causes io_uring to use a slower path as the driver cannot be trust not to block. brd can safely set the nowait flag, as worst case all it does is a NOIO allocation. For io_uring, this makes a substantial difference.

2023-02-16brd: check for REQ_NOWAIT and set correct page allocation maskJens Axboe1-20/+28
If REQ_NOWAIT is set, then do a non-blocking allocation if the operation is a write and we need to insert a new page. Currently REQ_NOWAIT cannot be set as the queue isn't marked as supporting nowait, this change is in preparation for allowing that. radix_tree_preload() warns on attempting to call it with an allocation mask that doesn't allow blocking. While that warning could arguably be removed, we need to handle radix insertion failures anyway as they are more likely if we cannot block to get memory. Remove legacy BUG_ON()'s and turn them into proper errors instead, one for the allocation failure and one for finding a page that doesn't match the correct index.

2023-02-16ASoC: SOF: Intel: hda-dai: fix possible stream_tag leakPierre-Louis Bossart1-4/+4
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.

2023-02-16block: sync mixed merged request's failfast with 1st bio'sMing Lei1-2/+33
We support mixed merge for requests/bios with different fastfail settings. When request fails, each time we only handle the portion with same failfast setting, then bios with failfast can be failed immediately, and bios without failfast can be retried. The idea is pretty good, but the current implementation has several defects: 1) initially RA bio doesn't set failfast, however bio merge code doesn't consider this point, and just check its failfast setting for deciding if mixed merge is required. Fix this issue by adding helper of bio_failfast(). 2) when merging bio to request front, if this request is mixed merged, we have to sync request's faifast setting with 1st bio's failfast. Fix it by calling blk_update_mixed_merge(). 3) when merging bio to request back, if this request is mixed merged, we have to mark the bio as failfast, because blk_update_request simply updates request failfast with 1st bio's failfast. Fix it by calling blk_update_mixed_merge(). Fixes one normal EXT4 READ IO failure issue, because it is observed that the normal READ IO is merged with RA IO, and the mixed merged request has different failfast setting with 1st bio's, so finally the normal READ IO doesn't get retried.

2023-02-16devlink: Fix netdev notifier chain corruptionIdo Schimmel3-14/+1
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.

2023-02-16igb: conditionalize I2C bit banging on external thermal sensor supportCorinna Vinschen1-10/+32
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 Johansen1-2/+1
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 Hellwig3-26/+26
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 Manana2-7/+12
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>

The function btrfs_bin_search() is just a wrapper around the function generic_bin_search(), which passes the same arguments plus a default low slot with a value of 0. This adds an unnecessary extra function call, since btrfs_bin_search() is not static. So improve on this by making btrfs_bin_search() an inline function that calls generic_bin_search(), renaming the later to btrfs_generic_bin_search() and exporting it.
