IB/srpt: Set srq_type to IB_SRQT_BASIC

2012-04-22T22:38:59+00:00

commit 6f3603367b8f7c34598fdfc1058622e0e1951e98 upstream.

Since commit 96104eda0169 ("RDMA/core: Add SRQ type field"), kernel
users of SRQs need to specify srq_type = IB_SRQT_BASIC in struct
ib_srq_init_attr, or else most low-level drivers will fail in
when srpt_add_one() calls ib_create_srq() and gets -ENOSYS.

(mlx4_ib works OK nearly all of the time, because it just needs
srq_type != IB_SRQT_XRC.  And apparently nearly everyone using
ib_srpt is using mlx4 hardware)

ib_srpt: Fix srpt_handle_cmd send_ioctx->ioctx_kref leak on exception

2012-04-02T17:31:55+00:00

commit 187e70a554e0f0717a65998bc9199945cbbd4692 upstream.

This patch addresses a bug in srpt_handle_cmd() failure handling where
send_ioctx->kref is being leaked with the local extra reference after init,
causing the expected kref_put() in srpt_handle_send_comp() to not be the final
call to invoke srpt_put_send_ioctx_kref() -> transport_generic_free_cmd() and
perform se_cmd descriptor memory release.

It also fixes a SCF_SCSI_RESERVATION_CONFLICT handling bug where this code
is incorrectly falling through to transport_handle_cdb_direct() after
invoking srpt_queue_status() to send SAM_STAT_RESERVATION_CONFLICT status.

Note this patch is for >= v3.3 mainline code, and current lio-core.git
code has already been converted to target_submit_cmd() + se_cmd->cmd_kref usage,
and internal ioctx->kref usage has been removed.  I'm including this patch
now into target-pending/for-next with a CC' for v3.3 stable.

IB/iser: Post initial receive buffers before sending the final login request

2012-04-02T17:31:53+00:00

commit 89e984e2c2cd14f77ccb26c47726ac7f13b70ae8 upstream.

An iser target may send iscsi NO-OP PDUs as soon as it marks the iSER
iSCSI session as fully operative.  This means that there is window
where there are no posted receive buffers on the initiator side, so
it's possible for the iSER RC connection to break because of RNR NAK /
retry errors.  To fix this, rely on the flags bits in the login
request to have FFP (0x3) in the lower nibble as a marker for the
final login request, and post an initial chunk of receive buffers
before sending that login request instead of after getting the login
response.

Quoth David:

1) GRO MAC header comparisons were ethernet specific, breaking other
   link types.  This required a multi-faceted fix to cure the originally
   noted case (Infiniband), because IPoIB was lying about it's actual
   hard header length.  Thanks to Eric Dumazet, Roland Dreier, and
   others.

2) Fix build failure when INET_UDP_DIAG is built in and ipv6 is modular.
   From Anisse Astier.

3) Off by ones and other bug fixes in netprio_cgroup from Neil Horman.

4) ipv4 TCP reset generation needs to respect any network interface
   binding from the socket, otherwise route lookups might give a
   different result than all the other segments received.  From Shawn
   Lu.

5) Fix unintended regression in ipv4 proxy ARP responses, from Thomas
   Graf.

6) Fix SKB under-allocation bug in sh_eth, from Yoshihiro Shimoda.

7) Revert skge PCI mapping changes that are causing crashes for some
   folks, from Stephen Hemminger.

8) IPV4 route lookups fill in the wildcarded fields of the given flow
   lookup key passed in, which is fine most of the time as this is
   exactly what the caller's want.  However there are a few cases that
   want to retain the original flow key values afterwards, so handle
   those cases properly.  Fix from Julian Anastasov.

9) IGB/IXGBE VF lookup bug fixes from Greg Rose.

10) Properly null terminate filename passed to ethtool flash device
    method, from Ben Hutchings.

11) S3 resume fix in via-velocity from David Lv.

12) Fix double SKB free during xmit failure in CAIF, from Dmitry
    Tarnyagin.

IPoIB: Stop lying about hard_header_len and use skb->cb to stash LL addresses

2012-02-08T23:26:54+00:00

Commit a0417fa3a18a ("net: Make qdisc_skb_cb upper size bound
explicit.") made it possible for a netdev driver to use skb->cb
between its header_ops.create method and its .ndo_start_xmit
method.  Use this in ipoib_hard_header() to stash away the LL address
(GID + QPN), instead of the "ipoib_pseudoheader" hack.  This allows
IPoIB to stop lying about its hard_header_len, which will let us fix
the L2 check for GRO.
