* nvmem: sc27xx: Convert nvmem offset to block indexFreeman Liu2019-01-311-4/+8
| | | | | | | | | | | | The Spreadtrum SC27XX efuse data are organized by blocks and each block contains 2 bytes data. Moreover the nvmem core always pass the offset in byte to the controller, so we should change the offset in byte to the correct block index and block offset to read the data.

* uio/uio_pci_generic: Disable bus-mastering on releaseVenkatesh Srinivas2019-01-311-0/+17
| | | | | | | | | | | | | | | | | | Userspace code using uio_pci_generic may enable bus-mastering by directly manipulating a PCI device's command register. If a userspace program enables bus-mastering but exits/crashes uncleanly, bus- mastering will still be enabled and stale DMA addresses may be programmed and live in the device. Disable bus-mastering unconditionally on last close of a UIO PCI fd to avoid this. If the device did not have bus-mastering enabled, pci_clear_master() is a no-op.

In that case, our allocation is not guaranteed to be zero-based anymore, and we have to make sure we allocate it on a boundary that is compatible with the PCI Multi-MSI constraints. Fix this by allocating the full region upfront instead of iterating over the number of MSIs. MSI-X are always allocated one by one, so this shouldn't change anything on that front.

Thus, a non-zero return should be treated as a -EFAULT error (as is done elsewhere in the kernel). However, mlx4_init_user_cqes() error handling simply returns the number of bytes not copied (instead of -EFAULT). Note, though, that this is a harmless bug: procedure mlx4_alloc_cq() (which is the only caller of mlx4_init_user_cqes()) treats any non-zero return as an error, but that returned error value is processed internally, and not passed further up the call stack.

Duplicate partitions occur because of the A/B backup scheme used by newer sfc NICs. Prior to this patch they cause sysfs_warn_dup errors because they have the same name, causing us not to expose any MTDs at all.

In order to allow this checksum to be received by the host descriptor data needs to be enlarged by 2 bytes to accommodate the checksum. In the case of MTU-sized packets without a VLAN tag the checksum were already accommodated by virtue of the space reserved for the VLAN tag. However, a packet of MTU-size with a VLAN tag consumed all packet data space provided by a descriptor leaving no space for the trailing checksum. This was not detected by the driver which incorrectly used the last two bytes of packet data as the checksum and truncate the packet by two bytes. This resulted all such packets being dropped. A work around is to disable RX checksum offload # ethtool -K eth0 rx off This patch resolves this problem by increasing the size available for packet data in RX descriptors by two bytes. Tested on R-Car E3 (r8a77990) ES1.0 based Ebisu-4D board v2 * Use sizeof(__sum16) directly rather than adding a driver-local #define for the size of the checksum provided by the hw (2 bytes).

They then either have a MODULE_LICENSE() of GPLv2 only, or an SPDX tag of GPLv2 only. Since the license text is much easier to understand than either the SPDX tag or the MODULE_LICENSE, use it as the definitive source of the licence, and fixup the others when there are contradictions.
