net: pass a sockptr_t into ->setsockopt

2020-07-24T22:41:54+00:00

Rework the remaining setsockopt code to pass a sockptr_t instead of a
plain user pointer.  This removes the last remaining set_fs(KERNEL_DS)
outside of architecture specific code.

Convert usage of IN_MULTICAST to ipv4_is_multicast

2019-09-05T07:38:32+00:00

IN_MULTICAST's primary intent is as a uapi macro.

Elsewhere in the kernel we use ipv4_is_multicast consistently.

This patch unifies linux's multicast checks to use that function
rather than this macro.

net/rds: Add RDS6_INFO_SOCKETS and RDS6_INFO_RECV_MESSAGES options

2019-08-15T18:40:03+00:00

Add support of the socket options RDS6_INFO_SOCKETS and
RDS6_INFO_RECV_MESSAGES which update the RDS_INFO_SOCKETS and
RDS_INFO_RECV_MESSAGES options respectively.  The old options work
for IPv4 sockets only.

net/rds: Check address length before reading address family

2019-04-12T17:25:03+00:00

syzbot is reporting uninitialized value at rds_connect() [1] and
rds_bind() [2]. This is because syzbot is passing ulen == 0 whereas
these functions expect that it is safe to access sockaddr->family field
in order to determine minimal address length for validation.

rds: add transport specific tos_map hook

2019-02-04T22:59:13+00:00

RDMA transport maps user tos to underline virtual lanes(VL)
for IB or DSCP values. RDMA CM transport abstract thats for
RDS. TCP transport makes use of default priority 0 and maps
all user tos values to it.

rds: add type of service(tos) infrastructure

2019-02-04T22:59:12+00:00

RDS Service type (TOS) is user-defined and needs to be configured
via RDS IOCTL interface. It must be set before initiating any
traffic and once set the TOS can not be changed. All out-going
traffic from the socket will be associated with its TOS.

socket: Add SO_TIMESTAMP[NS]_NEW

2019-02-03T19:17:31+00:00

Add SO_TIMESTAMP_NEW and SO_TIMESTAMPNS_NEW variants of
socket timestamp options.
These are the y2038 safe versions of the SO_TIMESTAMP_OLD
and SO_TIMESTAMPNS_OLD for all architectures.

Note that the format of scm_timestamping.ts[0] is not changed
in this patch.

sockopt: Rename SO_TIMESTAMP* to SO_TIMESTAMP*_OLD

2019-02-03T19:17:30+00:00

SO_TIMESTAMP, SO_TIMESTAMPNS and SO_TIMESTAMPING options, the
way they are currently defined, are not y2038 safe.
Subsequent patches in the series add new y2038 safe versions
of these options which provide 64 bit timestamps on all
architectures uniformly.
Hence, rename existing options with OLD tag suffixes.

Also note that kernel will not use the untagged SO_TIMESTAMP*
and SCM_TIMESTAMP* options internally anymore.
