uapi glibc compat: fix compile errors when glibc net/if.h included before linux/if.h

2016-05-19T01:35:07Z

[ Upstream commit 4a91cb61bb995e5571098188092e296192309c77 ] glibc's net/if.h contains copies of definitions from linux/if.h and these conflict and cause build failures if both files are included by application source code. Changes in uapi headers, which fixed header file dependencies to include linux/if.h when it was needed, e.g. commit 1ffad83d, made the net/if.h and linux/if.h incompatibilities visible as build failures for userspace applications like iproute2 and xtables-addons. This patch fixes compile errors when glibc net/if.h is included before linux/if.h: ./linux/if.h:99:21: error: redeclaration of enumerator ‘IFF_NOARP’ ./linux/if.h:98:23: error: redeclaration of enumerator ‘IFF_RUNNING’ ./linux/if.h:97:26: error: redeclaration of enumerator ‘IFF_NOTRAILERS’ ./linux/if.h:96:27: error: redeclaration of enumerator ‘IFF_POINTOPOINT’ ./linux/if.h:95:24: error: redeclaration of enumerator ‘IFF_LOOPBACK’ ./linux/if.h:94:21: error: redeclaration of enumerator ‘IFF_DEBUG’ ./linux/if.h:93:25: error: redeclaration of enumerator ‘IFF_BROADCAST’ ./linux/if.h:92:19: error: redeclaration of enumerator ‘IFF_UP’ ./linux/if.h:252:8: error: redefinition of ‘struct ifconf’ ./linux/if.h:203:8: error: redefinition of ‘struct ifreq’ ./linux/if.h:169:8: error: redefinition of ‘struct ifmap’ ./linux/if.h:107:23: error: redeclaration of enumerator ‘IFF_DYNAMIC’ ./linux/if.h:106:25: error: redeclaration of enumerator ‘IFF_AUTOMEDIA’ ./linux/if.h:105:23: error: redeclaration of enumerator ‘IFF_PORTSEL’ ./linux/if.h:104:25: error: redeclaration of enumerator ‘IFF_MULTICAST’ ./linux/if.h:103:21: error: redeclaration of enumerator ‘IFF_SLAVE’ ./linux/if.h:102:22: error: redeclaration of enumerator ‘IFF_MASTER’ ./linux/if.h:101:24: error: redeclaration of enumerator ‘IFF_ALLMULTI’ ./linux/if.h:100:23: error: redeclaration of enumerator ‘IFF_PROMISC’ The cases where linux/if.h is included before net/if.h need a similar fix in the glibc side, or the order of include files can be changed userspace code as a workaround.

v4l2-dv-timings.h: fix polarity for 4k formats

2016-05-04T21:49:08Z

commit 3020ca711871fdaf0c15c8bab677a6bc302e28fe upstream. The VSync polarity was negative instead of positive for the 4k CEA formats. I probably copy-and-pasted these from the DMT 4k format, which does have a negative VSync polarity.

[media] media-device: map new functions into old types for legacy API

2016-03-10T18:10:59Z

The legacy media controller userspace API exposes entity types that carry both type and function information. The new API replaces the type with a function. It preserves backward compatibility by defining legacy functions for the existing types and using them in drivers. This works fine, as long as newer entity functions won't be added. Unfortunately, some tools, like media-ctl with --print-dot argument rely on the now legacy MEDIA_ENT_T_V4L2_SUBDEV and MEDIA_ENT_T_DEVNODE numeric ranges to identify what entities will be shown. Also, if the entity doesn't match those ranges, it will ignore the major/minor information on devnodes, and won't be getting the devnode name via udev or sysfs. As we're now adding devices outside the old range, the legacy ioctl needs to map the new entity functions into a type at the old range, or otherwise we'll have a regression. Detected on all released media-ctl versions (e. g. versions <= 1.10). Fix this by deriving the type from the function to emulate the legacy API if the function isn't in the legacy functions range.

[media] media: Sanitise the reserved fields of the G_TOPOLOGY IOCTL arguments

2016-03-03T21:10:53Z

The argument structs are used in arrays for G_TOPOLOGY IOCTL. The arguments themselves do not need to be aligned to a power of two, but aligning them up to the largest basic type alignment (u64) on common ABIs is a good thing to do. The patch changes the size of the reserved fields to 5 or 6 u32's and aligns the size of the struct to 8 bytes so we do no longer depend on the compiler to perform the alignment. While at it, add __attribute__ ((packed)) to these structs as well. Signed-off-by: Sakari Ailus Signed-off-by: Mauro Carvalho Chehab

bpf: fix csum setting for bpf_set_tunnel_key

2016-02-24T21:23:47Z

The fix in 35e2d1152b22 ("tunnels: Allow IPv6 UDP checksums to be correctly controlled.") changed behavior for bpf_set_tunnel_key() when in use with IPv6 and thus uncovered a bug that TUNNEL_CSUM needed to be set but wasn't. As a result, the stack dropped ingress vxlan IPv6 packets, that have been sent via eBPF through collect meta data mode due to checksum now being zero. Since after LCO, we enable IPv4 checksum by default, so make that analogous and only provide a flag BPF_F_ZERO_CSUM_TX for the user to turn it off in IPv4 case.
