sparc32: fix struct ipc64_perm type definition

2020-02-14T21:30:58+00:00

[ Upstream commit 34ca70ef7d3a9fa7e89151597db5e37ae1d429b4 ]

As discussed in the strace issue tracker, it appears that the sparc32
sysvipc support has been broken for the past 11 years. It was however
working in compat mode, which is how it must have escaped most of the
regular testing.

The problem is that a cleanup patch inadvertently changed the uid/gid
fields in struct ipc64_perm from 32-bit types to 16-bit types in uapi
headers.

Both glibc and uclibc-ng still use the original types, so they should
work fine with compat mode, but not natively.  Change the definitions
to use __kernel_uid32_t and __kernel_gid32_t again.

net: Facility to report route quality of connected sockets

2016-02-26T03:01:22+00:00

This patch add the SO_CNX_ADVICE socket option (setsockopt only). The
purpose is to allow an application to give feedback to the kernel about
the quality of the network path for a connected socket. The value
argument indicates the type of quality report. For this initial patch
the only supported advice is a value of 1 which indicates "bad path,
please reroute"-- the action taken by the kernel is to call
dst_negative_advice which will attempt to choose a different ECMP route,
reset the TX hash for flow label and UDP source port in encapsulation,
etc.

This facility should be useful for connected UDP sockets where only the
application can provide any feedback about path quality. It could also
be useful for TCP applications that have additional knowledge about the
path outside of the normal TCP control loop.

soreuseport: setsockopt SO_ATTACH_REUSEPORT_[CE]BPF

2016-01-05T03:49:59+00:00

Expose socket options for setting a classic or extended BPF program
for use when selecting sockets in an SO_REUSEPORT group.  These options
can be used on the first socket to belong to a group before bind or
on any socket in the group after bind.

This change includes refactoring of the existing sk_filter code to
allow reuse of the existing BPF filter validation checks.

The GLIBC folks would like to eliminate socketcall support
