2020-05-21ice: report netlist version in .info_getJacob Keller
The flash memory for the ice hardware contains a block of information used for link management called the Netlist module. As this essentially represents another section of firmware, add its version information to the output of the driver's .info_get handler. This includes both a version and the first few bytes of a hash of the module contents. fw.netlist -> the version information extracted from the netlist module fw.netlist.build-> first 4 bytes of the hash of the contents, similar to fw.mgmt.build Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

Oleksij Rempel says: ==================== provide KAPI for SQI This patches are extending ethtool netlink interface to export Signal Quality Index (SQI). SQI provided by 100Base-T1 PHYs and can be used for cable diagnostic. Compared to a typical cable tests, this value can be only used after link is established. changes v3: - rename __ethtool_get_sqi* to linkstate_get_sqi*. And move this functions to the net/ethtool/linkstate.c - protect linkstate_get_sqi* with locking changes v2: - use u32 instead of u8 for SQI - add SQI_MAX field and callbacks - some style fixes in the rst. - do not convert index to shifted index. ==================== Signed-off-by: David S.

Currently, psample can only send the packet bits after decapsulation. The tunnel information is lost. Add the tunnel support. If the sampled packet has no tunnel info, the behavior is the same as before. If it has, add a nested metadata field named PSAMPLE_ATTR_TUNNEL and include the tunnel subfields if applicable.

Native ->setsockopt() handling of these options (MCAST_..._SOURCE_GROUP and MCAST_{,UN}BLOCK_SOURCE) consists of copyin + call of a helper that does the actual work.

Parallel to what the native setsockopt() does, except that unlike the native setsockopt() we do not use memdup_user() - we want the sockaddr_storage fields properly aligned, so we allocate 4 bytes more and copy compat_group_filter at the offset 4, which yields the proper alignments.

now we can do MCAST_MSFILTER in compat ->getsockopt() without playing silly buggers with copying things back and forth. We can form a native struct group_filter (sans the variable-length tail) on stack, pass that + pointer to the tail of original request to the helper doing the bulk of the work, then do the rest of copyout - same as the native getsockopt() does.

2020-05-20ip*_mc_gsfget(): lift copyout of struct group_filter into callersAl Viro
pass the userland pointer to the array in its tail, so that part gets copied out by our functions; copyout of everything else is done in the callers.

We want to get rid of compat_mc_[sg]etsockopt() and to have that stuff handled without compat_alloc_user_space(), extra copying through userland, etc. To do that we'll need ipv4 and ipv6 instances of ->compat_[sg]etsockopt() to manipulate the 32bit variants of mcast requests, so we need to move the definitions of those out of net/compat.c and into a public header.

2020-05-19igc: Refactor ethertype filtering codeAndre Guedes
The whole ethertype filtering code is implemented in igc_ethtool.c and mixes logic from ethtool and core parts. This patch refactors it so core logic is moved to igc_main.c, aligning the ethertype filtering code organization with the rest of the filtering code from the driver (MAC address and VLAN priority). Besides moving code to igc_main.c, this patch also does some minor improvements to the code. Below are some highlights. In case all filters are already in use and the user tries to add another filter, we return -ENOSPC instead of -EINVAL so a more meaningful error code is provided. This also aligns with the behavior implemented in MAC address filtering code. With this code refactoring, 'etype_bitmap' array in struct igc_adapter and 'etype_reg_index' in struct igc_nfc_filter are not needed anymore and are removed. Log messages are added to help debugging the ethertype filtering code.

2020-05-19Merge branch 'ndo_tunnel_ioctl'David S. Miller
Christoph Hellwig says: ==================== add a new ->ndo_tunnel_ctl method to avoid a few set_fs calls v2 both the ipv4 and ipv6 code have an ioctl each that can be used to create a tunnel using code that doesn't live in the core kernel or ipv6 module. Currently they call ioctls on the tunnel devices to create these, for which the code needs to override the address limit, which is a "feature" I plan to get rid of. Instead this patchset adds a new ->ndo_tunnel_ctl that can be used for the tunnel configuration using struct ip_tunnel_parm. The method is either invoked from a helper that does the uaccess and can be wired up as ndo_do_ioctl method, or directly from the magic IPV4/6 ioctls that create tunnels with kernel space arguments.
