[PATCH net-next v2 0/2] net/rds: Bug fix ports, part 2

[Allison Henderson <achender@kernel.org>]

Hi all,

This is the next batch of net/rds fixes ported from the Oracle UEK
kernel, following up on the first set now in net-next [1].  

This is v2 of patches 1 and 2 of "net/rds: Bug fix ports, part 2"
[2], which contained two initialization-hardening ports.  While
re-reviewing v1's patches 3 and 4 (the fastpath-lock teardown changes)
I found their locking needs more rework than a respin should carry, so
they are split out and will return as their own series together with
two companion fixes.  The two patches here are independent of them.

[PATCH net 1/2] net/rds: reinitialize to_be_dropped on rds_send_xmit() restart
  Port commit 7f52b9968d79 ("net/rds: rds_send_xmit should INIT_LIST_HEAD (&to_be_dropped) on restart")
  https://github.com/oracle/linux-uek/commit/7f52b9968d79 

[PATCH net 2/2] net/rds: initialize i_conn_path in rds_inc_init()
  Port commit 0ec6a520da4f ("rds: rds_inc_init() should initialize the inc->i_conn_path field")
  https://github.com/oracle/linux-uek/commit/0ec6a520da4f

Questions and comments appreciated!

Thanks,
Allison

v2:
  - Patch 1: the comment now names rds_send_remove_from_sock()
    instead of vaguely blaming "the callees", and the restart-time
    invariant is enforced with a WARN_ON_ONCE(): entries still on
    the list there would keep their message reference and their
    RDS_MSG_ON_SOCK accounting, so a silent re-init would orphan
    them.
  - Patch 2: for loopback the field held a live value written by
    rds_send_queue_rm(), not garbage; rds_loop_xmit() now uses
    rds_inc_path_init() so the re-initialization keeps it valid, and
    the commit message describes the two transports accurately.
