If we reset the virtio-blk device before the requests already dispatched to the virtio-blk driver from the block layer are finised, we will stuck in blk_cleanup_queue() and the remove will fail. blk_cleanup_queue() calls blk_drain_queue() to drain all requests queued before DEAD marking. However it will never success if the device is already stopped. We'll have q->in_flight[] > 0, so the drain will not finish. How to reproduce the race: 1. hot-plug a virtio-blk device 2. keep reading/writing the device in guest 3. hot-unplug while the device is busy serving I/O Test: ~1000 rounds of hot-plug/hot-unplug test passed with this patch. Changes in v3: - Drop blk_abort_queue and blk_abort_request - Use __blk_end_request_all to complete request dispatched to driver Changes in v2: - Drop req_in_flight - Use virtqueue_detach_unused_buf to get request dispatched to driver Signed-off-by: NAsias He <asias@redhat.com> Signed-off-by: NRusty Russell <rusty@rustcorp.com.au>

This patch fixes a bug in iscsit_allocate_iovecs() where iov_count was incorrectly calculated using min(1UL, data_length / PAGE_SIZE) instead of max(1UL, data_length / PAGE_SIZE), that ends up triggering an OOPs for large block I/O when the SGL <-> iovec mapping exceeds the bogus iov_count allocation size. This is a regression introduced during the iscsi-target conversion back to using core memory allocation here: commit bfb79eac Author: Andy Grover <agrover@redhat.com> Date: Tue Apr 3 15:51:29 2012 -0700 target/iscsi: Go back to core allocating data buffer for cmd Cc: Andy Grover <agrover@redhat.com> Signed-off-by: NNicholas Bellinger <nab@linux-iscsi.org>

Add the ZTE (Vodafone) K3765-Z to the whitelist. This requires the previous patch to make the whitelist with forced interface 4 generic or the device fails to initialise. After applying this patch and loading the Option driver without usb-modeswitch's bind all interfaces trick, a wwan0 net interface and /dev/cdc-wdm0 device file were created. Using Bjorn Mork's perl connection script a connection was made to a mobile network using QMI and the network interface's IPv4 address was configured OK.

Change the forced interface 4 whitelist to use the generic shared binder instead of the Gobi specific one. Certain ZTE devices (K3520-Z & K3765-Z) don't work with the Gobi version, but function quite happily with the generic. This has been tested with the following devices: K3520-Z K3565-Z K3765-Z K4505-Z It hasn't been tested with the ZTE MF820D, which is the only other device that uses this whitelist at present. Although Bjorn doesn't expect any problems, any testing with that device would be appreciated.

We need to use a different loop index for mlx4_counter_alloc() and for device_create_file() iterations: the mlx4_counter_alloc() loop index is used in the error flow to free counters. If the same loop index is used for device_create_file() and, say, the device_create_file() loop fails on the first iteration, the allocated counters will not be freed.

The current error flow code was releasing the IB connection object and calling iscsi_destroy_endpoint() directly without going through the reference counting mechanism introduced in commit 39ff05db ("IB/iser: Enhance disconnection logic for multi-pathing"). This resulted in a double free of the iscsi endpoint object, which causes a kernel NULL pointer dereference. Fix that by plugging into the IB conn reference counting correctly.

Enable IB ULPs to use a larger portion of the device EQs (which map to IRQs). The mlx4_ib driver follows the mlx4_core framework of the EQs to be divided among the device ports. In this scheme, for each IB port, the number of allocated EQs follows the number of cores, subject to other system constraints, such as number available MSI-X vectors.

由 Mike Snitzer 提交于
When the thin pool target clears the discard_passdown parameter internally, it incorrectly changes the table line reported to userspace. This breaks dumb string comparisons on these table lines in generic userspace device-mapper library code and leads to tables being reloaded repeatedly when nothing is actually meant to be changing. This patch corrects this by no longer changing the table line when discard passdown was disabled. We can still tell when discard passdown is overridden by looking for the message "Discard unsupported by data device (sdX): Disabling discard passdown." This automatic detection is also moved from the 'load' to the 'resume' so that it is re-evaluated should the properties of underlying devices change.
