2022-09-21s390/dasd: add ioctl to perform a swap of the drivers copy pairStefan Haberland1-0/+53
The newly defined ioctl BIODASDCOPYPAIRSWAP takes a structure that specifies a copy pair that should be swapped. It will call the device discipline function to perform the swap operation. The structure looks as followed: struct dasd_copypair_swap_data_t { char primary[20]; char secondary[20]; __u8 reserved[64]; }; where primary is the old primary device that will be replaced by the secondary device. The old primary will become a secondary device afterwards.

2022-09-21s390/dasd: add copy pair swap capabilityStefan Haberland4-1/+117
In case of errors or misbehaviour of the primary device a controlled failover to one of the configured secondary devices needs to be performed. The swap processing stops I/O on the primary device, all requests are re-queued to the blocklayer queue, the entries in the copy relation are swapped and finally the link to the blockdevice is moved from primary to secondary dasd device. After this, the secondary becomes the new primary device and I/O is restarted on that device.

2022-09-21s390/dasd: add copy pair setupStefan Haberland4-17/+623
A copy relation that is configured on the storage server side needs to be enabled separately in the device driver. A sysfs interface is created that allows userspace tooling to control such setup. The following sysfs entries are added to store and read copy relation information: copy_pair - Add/Delete a copy pair relation to the DASD device driver - Query all previously added copy pair relations copy_role - Query the copy pair role of the device To add a copy pair to the DASD device driver it has to be specified through the sysfs attribute copy_pair. Only one secondary device can be specified at a time together with the primary device. Both, secondary and primary can be used equally to define the copy pair. The secondary devices have to be offline when adding the copy relation. The primary device needs to be specified first followed by the comma separated secondary device. Read from the copy_pair attribute to get the current setup and write "clear" to the attribute to delete any existing setup. Example: $ echo 0.0.9700,0.0.9740 > /sys/bus/ccw/devices/0.0.9700/copy_pair $ cat /sys/bus/ccw/devices/0.0.9700/copy_pair 0.0.9700,0.0.9740 During device online processing the required data will be read from the storage server and the information will be compared to the setup requested through the copy_pair attribute. The registration of the primary and secondary device will be handled accordingly. A blockdevice is only allocated for copy relation primary devices. To query the copy role of a device read from the copy_role sysfs attribute. Possible values are primary, secondary, and none. Example: $ cat /sys/bus/ccw/devices/0.0.9700/copy_role primary Signed-off-by: Stefan Haberland <sth@linux.ibm.com> Reviewed-by: Jan Hoeppner <hoeppner@linux.ibm.com> Link: https://lore.kernel.org/r/20220920192616.808070-4-sth@linux.ibm.com Signed-off-by: Jens Axboe <axboe@kernel.dk>

2022-09-19bcache: fix set_at_max_writeback_rate() for multiple attached devicesColy Li1-21/+52
Inside set_at_max_writeback_rate() the calculation in following if() check is wrong, if (atomic_inc_return(&c->idle_counter) < atomic_read(&c->attached_dev_nr) * 6) Because each attached backing device has its own writeback thread running and increasing c->idle_counter, the counter increates much faster than expected. The correct calculation should be, (counter / dev_nr) < dev_nr * 6 which equals to, counter < dev_nr * dev_nr * 6 This patch fixes the above mistake with correct calculation, and helper routine idle_counter_exceeded() is added to make code be more clear.

2022-09-19nvme-tcp: print actual source IP address through sysfs "address" attrMartin Belanger1-1/+20
TCP transport relies on the routing table to determine which source address and interface to use when making a connection. Currently, there is no way to tell from userspace where a connection was made. This patch exposes the actual source address using a new field named "src_addr=" in the "address" attribute. This is needed to diagnose and identify connectivity issues. With the source address we can infer the interface associated with each connection. This was tested with nvme-cli 2.0 to verify it does not have any adverse effect. The new "src_addr=" field will simply be displayed in the output of the "list-subsys" or "list -v" commands as shown here. $ nvme list-subsys nvme-subsys0 - NQN=nqn.2014-08.org.nvmexpress.discovery \ +- nvme0 tcp traddr=192.168.56.1,trsvcid=8009,src_addr=192.168.56.101 live Signed-off-by: Martin Belanger <martin.belanger@dell.com> Reviewed-by: Sagi Grimberg <sagi@grimberg.me> Reviewed-by: Chaitanya Kulkarni <kch@nvidia.com> Signed-off-by: Christoph Hellwig <hch@lst.de>
2022-09-19nvmet-tcp: don't map pages which can't come from HIGHMEMFabio M. De Francesco1-31/+13
kmap() is being deprecated in favor of kmap_local_page().[1] There are two main problems with kmap(): (1) It comes with an overhead as mapping space is restricted and protected by a global lock for synchronization and (2) it also requires global TLB invalidation when the kmap’s pool wraps and it might block when the mapping space is fully utilized until a slot becomes available. The pages which will be mapped are allocated in nvmet_tcp_map_data(), using the GFP_KERNEL flag. This assures that they cannot come from HIGHMEM. This imply that a straight page_address() can replace the kmap() of sg_page(sg) in nvmet_tcp_map_pdu_iovec(). As a side effect, we might also delete the field "nr_mapped" from struct "nvmet_tcp_cmd" because, after removing the kmap() calls, there would be no longer any need of it. In addition, there is no reason to use a kvec for the command receive data buffers iovec, use a bio_vec instead and let iov_iter handle the buffer mapping and data copy. Test with blktests on a QEMU/KVM x86_32 VM, 6GB RAM, booting a kernel with HIGHMEM64GB enabled.

2022-09-19nvme-pci: iod npages fits in s8Keith Busch1-13/+16
The largest allowed transfer is 4MB, which can use at most 1025 PRPs. Each PRP is 8 bytes, so the maximum number of 4k nvme pages needed for the iod_list is 3, which fits in an 's8' type. While modifying this field, change the name to "nr_allocations" to better represent that this is referring to the number of units allocated from a dma_pool. Also introduce a BUILD_BUG_ON to ensure we never accidently increase the largest transfer limit beyond 127 chained prp lists.

The other case where we have less queues than previously, the connection attempt will fail because the target doesn't support the old number of queues and we end up in a reconnect loop.

2022-08-21i2c: imx: Make sure to unregister adapter on remove()Uwe Kleine-König1-9/+11
If for whatever reasons pm_runtime_resume_and_get() fails and .remove() is exited early, the i2c adapter stays around and the irq still calls its handler, while the driver data and the register mapping go away. So if later the i2c adapter is accessed or the irq triggers this results in havoc accessing freed memory and unmapped registers. So unregister the software resources even if resume failed, and only skip the hardware access in that case.
