rds: ib: update WR sizes when bringing up connection

2019-11-16T20:59:08+00:00

Currently WR sizes are updated from rds_ib_sysctl_max_send_wr and
rds_ib_sysctl_max_recv_wr when a connection is shut down. As a result,
a connection being down while rds_ib_sysctl_max_send_wr or
rds_ib_sysctl_max_recv_wr are updated, will not update the sizes when
it comes back up.

Move resizing of WRs to rds_ib_setup_qp so that connections will be setup
with the most current WR sizes.

net/rds: Fix error handling in rds_ib_add_one()

2019-10-02T16:16:57+00:00

rds_ibdev:ipaddr_list and rds_ibdev:conn_list are initialized
after allocation some resources such as protection domain.
If allocation of such resources fail, then these uninitialized
variables are accessed in rds_ib_dev_free() in failure path. This
can potentially crash the system. The code has been updated to
initialize these variables very early in the function.

net/rds: Check laddr_check before calling it

2019-09-27T10:10:55+00:00

In rds_bind(), laddr_check is called without checking if it is NULL or
not.  And rs_transport should be reset if rds_add_bound() fails.

net/rds: Fix 'ib_evt_handler_call' element in 'rds_ib_stat_names'

2019-09-15T18:56:19+00:00

All entries in 'rds_ib_stat_names' are stringified versions
of the corresponding "struct rds_ib_statistics" element
without the "s_"-prefix.

Fix entry 'ib_evt_handler_call' to do the same.

net/rds: An rds_sock is added too early to the hash table

2019-09-11T14:05:40+00:00

In rds_bind(), an rds_sock is added to the RDS bind hash table before
rs_transport is set.  This means that the socket can be found by the
receive code path when rs_transport is NULL.  And the receive code
path de-references rs_transport for congestion update check.  This can
cause a panic.  An rds_sock should not be added to the bind hash table
before all the needed fields are set.

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.
