fs: dlm: check on existing node address

2020-11-10T18:14:20+00:00

This patch checks if we add twice the same address to a per node address
array. This should never be the case and we report -EEXIST to the user
space.

fs: dlm: fix check for multi-homed hosts

2020-11-10T18:14:20+00:00

This patch will use the runtime array size dlm_local_count variable
to check the actual size of the dlm_local_addr array. There exists
currently a cleanup bug, because the tcp_listen_for_all() functionality
might check on a dangled pointer.

fs: dlm: listen socket out of connection hash

2020-11-10T18:14:20+00:00

This patch introduces a own connection structure for the listen socket
handling instead of handling the listen socket as normal connection
structure in the connection hash. We can remove some nodeid equals zero
validation checks, because this nodeid should not exists anymore inside
the node hash. This patch also removes the sock mutex in
accept_from_sock() function because this function can't occur in another
parallel context if it's scheduled on only one workqueue.

fs: dlm: move connect callback in node creation

2020-11-10T18:14:20+00:00

This patch moves the assignment for the connect callback to the node
creation instead of assign some dummy functionality. The assignment
which connect functionality will be used will be detected according to
the configfs setting.

fs: dlm: add helper for init connection

2020-11-10T18:14:20+00:00

This patch will move the connection structure initialization into an
own function. This avoids cases to update the othercon initialization.

fs: dlm: handle non blocked connect event

2020-11-10T18:14:20+00:00

The manpage of connect shows that in non blocked mode a writeability
indicates successful connection event. This patch is handling this event
inside the writeability callback. In case of SCTP we use blocking
connect functionality which indicates a successful connect when the
function returns with a successful return value.

2020-11-10T18:14:20+00:00

close occurs.
