2021-12-06scsi: qedi: Fix cmd_cleanup_cmpl counter mismatch issueManish Rangankar
When issued LUN reset under heavy I/O we hit the qedi WARN_ON because of a mismatch in firmware I/O cmd cleanup request count and I/O cmd cleanup response count received. The mismatch is because of a race caused by the postfix increment of cmd_cleanup_cmpl.

2021-12-06perf test: Fix 'Simple expression parser' test on arch without CPU die ↵Thomas Richter
topology info Some platforms do not have CPU die support, for example s390. Commit Cc: Ian Rogers <irogers@google.com> Fixes: fdf1e29b6118c18f ("perf expr: Add metric literals for topology.") fails on s390: # perf test -Fv 7 ... # FAILED tests/expr.c:173 #num_dies >= #num_packages ---- end ---- Simple expression parser: FAILED! # Investigating this issue leads to these functions: build_cpu_topology() +--> has_die_topology(void) { struct utsname uts; if (uname(&uts) < 0) return false; if (strncmp(uts.machine, "x86_64", 6)) return false; .... } which always returns false on s390. The caller build_cpu_topology() checks has_die_topology() return value. On false the the struct cpu_topology::die_cpu_list is not contructed and has zero entries. This leads to the failing comparison: #num_dies >= #num_packages. s390 of course has a positive number of packages. Fix this and check if the function build_cpu_topology() did build up a die_cpus_list. The number of entries in this list should be larger than 0. If the number of list element is zero, the die_cpus_list has not been created and the check in function test__expr(): TEST_ASSERT_VAL("#num_dies >= #num_packages", \ num_dies >= num_packages) always fails.

2021-12-06tools build: Remove needless libpython-version feature check that breaks ↵Arnaldo Carvalho de Melo

The space allowed for new attributes can be too small if existing header information is large. That can happen, for example, if there are very many CPUs, due to having an event ID per CPU per event being stored in the header information. Fix by adding the existing header.data_offset. Also increase the extra space allowed to 8KiB and align to a 4KiB boundary for neatness.

2021-12-06ethtool: do not perform operations on net devices being unregisteredAntoine Tenart
There is a short period between a net device starts to be unregistered and when it is actually gone. In that time frame ethtool operations could still be performed, which might end up in unwanted or undefined behaviours[1]. Do not allow ethtool operations after a net device starts its unregistration. This patch targets the netlink part as the ioctl one isn't affected: the reference to the net device is taken and the operation is executed within an rtnl lock section and the net device won't be found after unregister.

This happened because the DJM 750 MK2 was added last to the Pioneer DJM device table index and defined as 0x4 but was added to snd_djm_devices[] just after the DJM 750 (MK1) entry instead of last, after the DJM 900 NXS2. This escaped review. To prevent that from ever happening again, Takashi Iwai suggested to use C99 array designators in snd_djm_devices[] instead of simply reordering the entries.

2021-12-06nvme: report write pointer for a full zone as zone start + zone lenNiklas Cassel
The write pointer in NVMe ZNS is invalid for a zone in zone state full. The same also holds true for ZAC/ZBC. The current behavior for NVMe is to simply propagate the wp reported by the drive, even for full zones. Since the wp is invalid for a full zone, the wp reported by the drive may be any value. The way that the sd_zbc driver handles a full zone is to always report the wp as zone start + zone len, regardless of what the drive reported. null_blk also follows this convention. Do the same for NVMe, so that a BLKREPORTZONE ioctl reports the write pointer for a full zone in a consistent way, regardless of the interface of the underlying zoned block device. blkzone report before patch: start: 0x000040000, len 0x040000, cap 0x03e000, wptr 0xfffffffffffbfff8 reset:0 non-seq:0, zcond:14(fu) [type: 2(SEQ_WRITE_REQUIRED)] blkzone report after patch: start: 0x000040000, len 0x040000, cap 0x03e000, wptr 0x040000 reset:0 non-seq:0, zcond:14(fu) [type: 2(SEQ_WRITE_REQUIRED)] Signed-off-by: Niklas Cassel <niklas.cassel@wdc.com> Reviewed-by: Keith Busch <kbusch@kernel.org> Reviewed-by: Damien Le Moal <damien.lemoal@opensource.wdc.com> Reviewed-by: Johannes Thumshirn <johannes.thumshirn@wdc.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
2021-12-06nvme: disable namespace access for unsupported metadataKeith Busch
The only fabrics target that supports metadata handling through the separate integrity buffer is RDMA. It is currently usable only if the size is 8B per block and formatted for protection information. If an rdma target were to export a namespace with a different format (ex: 4k+64B), the driver will not be able to submit valid read/write commands for that namespace. Suppress setting the metadata feature in the namespace so that the gendisk capacity will be set to 0. This will prevent read/write access through the block stack, but will continue to allow ioctl passthrough commands.
