The usnic_verbs kernel module was clearly marked with the following in its code: MODULE_LICENSE("Dual BSD/GPL"); However, we accidentally left a few clauses of the BSD text out of the license header in all the source files. This commit fixes that: all the files are properly dual BSD/GPL-licensed. Contributors that might have been confused by this have been contacted to get their permission and are Cc:ed here.

When performing sendonly joins, we queue the packets that trigger the join until the join completes. This may take on the order of hundreds of milliseconds. It is easy to have many more than three packets come in during that time. Expand the maximum queue depth in order to try and prevent dropped packets during the time it takes to join the multicast group. Signed-off-by: NDoug Ledford <dledford@redhat.com>

Since IPoIB should, as much as possible, emulate how multicast sends work on Ethernet for regular TCP/IP apps, there should be no requirement to subscribe to a multicast group before your sends are properly sent. However, due to the difference in how multicast is handled on InfiniBand, we must join the appropriate multicast group before we can send to it. Previously we tried not to trigger the auto-create feature of the subnet manager when doing this because we didn't have tracking of these sendonly groups and the auto-creation might never get undone. The previous patch added timing to these sendonly joins and allows us to leave them after a reasonable idle expiration time. So supply all of the information needed to auto-create group.

Since mlx5 driver cannot rely on registration using the reserved lkey (global_dma_lkey) it used to allocate a private physical address lkey for each allocated pd.

Commit 96249d70 ("IB/core: Guarantee that a local_dma_lkey is available") allows ULPs that make use of the local dma key to keep working as before by allocating a DMA MR with local permissions and converted these consumers to use the MR associated with the PD rather then device->local_dma_lkey. ConnectIB has some known issues with memory registration using the local_dma_lkey (SEND, RDMA, RECV seems to work ok). Thus don't expose support for it (remove device->local_dma_lkey setting), and take advantage of the above commit such that no regression is introduced to working systems. The local_dma_lkey support will be restored in CX4 depending on FW capability query. Signed-off-by: NSagi Grimberg <sagig@mellanox.com> Signed-off-by: NDoug Ledford <dledford@redhat.com>

Some of the device files are required to be user accessible for PSM while most should remain accessible only by root. Add a parameter to hfi1_cdev_init which controls if the user should have access to this device which places it in a different class with the appropriate devnode callback. In addition set the devnode call back for the existing class to be a bit more explicit for those permissions.

The commit [b6789320: leds:lp55xx: fix firmware loading error] tries to address the firmware file handling with user helper, but it sets a wrong Kconfig CONFIG_FW_LOADER_USER_HELPER_FALLBACK. Since the wrong option was enabled, the system got a regression -- it suffers from the unexpected long delays for non-present firmware files. This patch corrects the Kconfig dependency to the right one, CONFIG_FW_LOADER_USER_HELPER. This doesn't change the fallback behavior but only enables UMH when needed.

If a mux clock is initialised (by hardware or firmware) with an invalid parent, its ->get_parent() can return an out of range index. For example, the generic mux clock attempts to return -EINVAL, which due to the u8 return type ends up a rather large number. Using this index with the parent_names[] array results in an invalid pointer and (usually) a crash in the following strcmp(). This patch adds a check for the parent index being in range, ignoring clocks reporting invalid values.

The translation of flags is as follows: IRQF_VALID -> !IRQ_NOREQUEST IRQF_PROBE -> !IRQ_NOPROBE IRQF_NOAUTOEN -> IRQ_NOAUTOEN For IRQs managed by an irqdomain, the irqdomain core code handles clearing and setting IRQ_NOREQUEST already, so there is no need to do this in .map() functions and we can simply remove the set_irq_flags calls.
