2015-06-05iscsi_ibft: filter null v4-mapped v6 addressesChris Leech1-15/+21
I've had reports of UEFI platforms failing iSCSI boot in various configurations, that ended up being caused by network initialization scripts getting tripped up by unexpected null addresses (0.0.0.0) being reported for gateways, dhcp servers, and dns servers. The tianocore EDK2 iSCSI driver generates an iBFT table that always uses IPv4-mapped IPv6 addresses for the NIC structure fields. This results in values that are "not present or not specified" being reported as ::ffff:0.0.0.0 rather than all zeros as specified. The iscsi_ibft module filters unspecified fields from the iBFT from sysfs, preventing userspace from using invalid values and making it easy to check for the presence of a value. This currently fails in regard to these mapped null addresses. In order to remain consistent with how the iBFT information is exposed, we should accommodate the behavior of the tianocore iSCSI driver as it's already in the wild in a large number of servers. Tested under qemu using an OVMF build of tianocore EDK2.

2015-06-06drm: fix writing to /sys/class/drm/*/statusRussell King1-1/+1
Writing to a file is supposed to return the number of bytes written. Returning zero unfortunately causes bash to constantly spin trying to write to the sysfs file, to such an extent that even ^c and ^z have no effect. The only way out of that is to kill the shell and log back in. This isn't nice behaviour. Fix it by returning the number of characters written to sysfs files.

2015-06-04Input: alps - do not reduce trackpoint speed by halfHans de Goede1-3/+2
On some v7 devices (e.g. Lenovo-E550) the deltas reported are typically only in the 0-1 range dividing this by 2 results in a range of 0-0. And even for v7 devices where this does not lead to making the trackstick entirely unusable, it makes it twice as slow as before we added v7 support and were using the ps/2 mouse emulation of the dual point setup. If some kind of generic slowdown is actually necessary for some devices, then that belongs in userspace, not in the kernel.

For that another function (dma_zalloc_coherent) should be used. But all other x86 DMA-API implementation I checked zero out the memory, so that some drivers rely on it and break when it is not.

In d74b9027a4da ("PCI: Consider additional PF's IOV BAR alignment in sizing and assigning"), we store additional alignment in realloc_head and take this into consideration for assignment. In __assign_resources_sorted(), we changed dev_res->res->start, then used resource_start() (which depends on res->start), so the recomputed res->end was completely bogus. Even if we'd had the correct size, the end would have been off by one. Preserve the resource size when we adjust its alignment.

2015-06-01xen: netback: read hotplug script once at start of day.Ian Campbell1-14/+19
When we come to tear things down in netback_remove() and generate the uevent it is possible that the xenstore directory has already been removed (details below). In such cases netback_uevent() won't be able to read the hotplug script and will write a xenstore error node. A recent change to the hypervisor exposed this race such that we now sometimes lose it (where apparently we didn't ever before). Instead read the hotplug script configuration during setup and use it for the lifetime of the backend device. The apparently more obvious fix of moving the transition to state=Closed in netback_remove() to after the uevent does not work because it is possible that we are already in state=Closed (in reaction to the guest having disconnected as it shutdown). Being already in Closed means the toolstack is at liberty to start tearing down the xenstore directories. In principal it might be possible to arrange to unregister the device sooner (e.g on transition to Closing) such that xenstore would still be there but this state machine is fragile and prone to anger... A modern Xen system only relies on the hotplug uevent for driver domains, when the backend is in the same domain as the toolstack it will run the necessary setup/teardown directly in the correct sequence wrt xenstore changes.

Apparently we can have requests even if though the active list is empty, so do the request retirement regardless of whether there's anything on the active list.

2015-05-30bna: fix firmware loading on big-endian machinesIvan Vecera1-0/+7
Firmware required by bna is stored in appropriate files as sequence of LE32 integers. After loading by request_firmware() they need to be byte-swapped on big-endian arches. Without this conversion the NIC is unusable on big-endian machines. Cc: Rasesh Mody <rasesh.mody@qlogic.com> Signed-off-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: David S.

2015-05-30iser-target: Fix error path in isert_create_pi_ctx()Roland Dreier1-3/+3
We don't assign pi_ctx to desc->pi_ctx until we're certain to succeed in the function. That means the cleanup path should use the local pi_ctx variable, not desc->pi_ctx.

2015-05-30target: Use a PASSTHROUGH flag instead of transport_typesAndy Grover10-18/+15
It seems like we only care if a transport is passthrough or not. Convert transport_type to a flags field and replace TRANSPORT_PLUGIN_* with a flag, TRANSPORT_FLAG_PASSTHROUGH.

2015-05-30target: Move passthrough CDB parsing into a common functionAndy Grover3-94/+76
Aside from whether they handle BIDI ops or not, parsing of the CDB by kernel and user SCSI passthrough modules should be identical. Move this into a new passthrough_parse_cdb() and call it from tcm-pscsi and tcm-user.

2015-05-30target/user: Only support full command pass-throughAndy Grover1-50/+74
After much discussion, give up on only passing a subset of SCSI commands to userspace and pass them all. Based on what pscsi is doing, make sure to set SCF_SCSI_DATA_CDB for I/O ops, and define attributes identical to pscsi. Make hw_block_size configurable via dev param. Remove mention of command filtering from tcmu-design.txt.

See https://bugzilla.redhat.com/show_bug.cgi?id=1025672 We need to put() the reference to the scsi host that we got in pscsi_configure_device(). In VIRTUAL_HOST mode it is associated with the dev_virt, not the hba_virt.

2015-05-30target: Fix se_tpg_tfo->tf_subsys regression + remove tf_subsystemChristoph Hellwig6-61/+31
There is just one configfs subsystem in the target code, so we might as well add two helpers to reference / unreference it from the core code instead of passing pointers to it around. This fixes a regression introduced for v4.1-rc1 with commit 9ac8928e6, where configfs_depend_item() callers using se_tpg_tfo->tf_subsys would fail, because the assignment from the original target_core_subsystem[] is no longer happening at target_register_template() time.
