rds: Changing IP address internal representation to struct in6_addr

2018-07-24T04:17:44+00:00

This patch changes the internal representation of an IP address to use struct in6_addr. IPv4 address is stored as an IPv4 mapped address. All the functions which take an IP address as argument are also changed to use struct in6_addr. But RDS socket layer is not modified such that it still does not accept IPv6 address from an application. And RDS layer does not accept nor initiate IPv6 connections. v2: Fixed sparse warnings.

rds: clean up loopback rds_connections on netns deletion

2018-06-27T01:11:03+00:00

The RDS core module creates rds_connections based on callbacks from rds_loop_transport when sending/receiving packets to local addresses. These connections will need to be cleaned up when they are created from a netns that is not init_net, and that netns is deleted. Add the changes aligned with the changes from commit ebeeb1ad9b8a ("rds: tcp: use rds_destroy_pending() to synchronize netns/module teardown and rds connection/workq management") for rds_loop_transport Reported-and-tested-by: syzbot+4c20b3866171ce8441d2@syzkaller.appspotmail.com Acked-by: Santosh Shilimkar Signed-off-by: Sowmini Varadhan Signed-off-by: David S.

rds: avoid unenecessary cong_update in loop transport

2018-06-15T02:01:49+00:00

Loop transport which is self loopback, remote port congestion update isn't relevant. Infact the xmit path already ignores it. Receive path needs to do the same.

RDS: TCP: Hooks to set up a single connection path

2016-07-01T20:45:17+00:00

This patch adds ->conn_path_connect callbacks in the rds_transport that are used to set up a single connection path. Acked-by: Santosh Shilimkar Signed-off-by: Sowmini Varadhan Signed-off-by: David S. Miller

RDS: TCP: make receive path use the rds_conn_path

2016-07-01T20:45:17+00:00

The ->sk_user_data contains a pointer to the rds_conn_path for the socket. Use this consistently in the rds_tcp_data_ready callbacks to get the rds_conn_path for rds_recv_incoming. Acked-by: Santosh Shilimkar Signed-off-by: Sowmini Varadhan Signed-off-by: David S. Miller

RDS: Rework path specific indirections

2016-07-01T20:45:17+00:00

Refactor code to avoid separate indirections for single-path and multipath transports. All transports (both single and mp-capable) will get a pointer to the rds_conn_path, and can trivially derive the rds_connection from the ->cp_conn.

RDS: split out connection specific state from rds_connection to rds_conn_path

2016-06-15T06:50:41+00:00

In preparation for multipath RDS, split the rds_connection structure into a base structure, and a per-path struct rds_conn_path. The base structure tracks information and locks common to all paths. The workqs for send/recv/shutdown etc are tracked per rds_conn_path. Thus the workq callbacks now work with rds_conn_path. This commit allows for one rds_conn_path per rds_connection, and will be extended into multiple conn_paths in subsequent commits. Signed-off-by: Sowmini Varadhan Signed-off-by: David S. Miller

RDS: use gfp flags from caller in conn_alloc()

2012-03-22T23:29:58+00:00

We should be using the gfp flags the caller specified here, instead of GFP_KERNEL. I think this might be a bugfix, depending on the value of "sock->sk->sk_allocation" when we call rds_conn_create_outgoing() in rds_sendmsg(). Otherwise, it's just a cleanup.
