2019-10-28RDMA/cm: Use specific keyword to check defineLeon Romanovsky1-1/+1
There is a specific define keyword to check if define exists or not, let's use it instead of open-coded variant.

2019-03-25RDMA: Use __packed annotation instead of __attribute__ ((packed))Erez Alfasi1-11/+11
"__attribute__" set of macros has been standardized, have became more potentially portable and consistent code back in v2.6.21 by commit 82ddcb040 ("[PATCH] extend the set of "__attribute__" shortcut macros"). Moreover, nowadays checkpatch.pl warns about using __attribute__((packed)) instead of __packed. This patch converts all the "__attribute__ ((packed))" annotations to "__packed" within the RDMA subsystem.

2018-07-09IB/cm: Remove unused and erroneous msg sequence encodingHåkon Bugge1-7/+0
In cm_form_tid(), a two bit message sequence number is OR'ed into bit 31-30 of the lower TID value. After commit f06d26537559 ("IB/cm: Randomize starting comm ID"), the local_id is XOR'ed with a 32-bit random value. Hence, bit 31-30 in the lower TID now has an arbitrarily value and it makes no sense to OR in the message sequence number. Adding to that, the evolution in use of IDR routines in cm_alloc_id() has always had the possibility of returning a value with bit 30 set. In addition, said bits are never checked. Hence, remove the encoding and the corresponding enum. Signed-off-by: Håkon Bugge <haakon.bugge@oracle.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
2015-05-05IB/core: Fix unaligned accessesDavid Ahern1-2/+2
Addresses the following kernel logs seen during boot of sparc systems: Kernel unaligned access at TPC[103bce50] cm_find_listen+0x34/0xf8 [ib_cm] Kernel unaligned access at TPC[103bce50] cm_find_listen+0x34/0xf8 [ib_cm] Kernel unaligned access at TPC[103bce50] cm_find_listen+0x34/0xf8 [ib_cm] Kernel unaligned access at TPC[103bce50] cm_find_listen+0x34/0xf8 [ib_cm] Kernel unaligned access at TPC[103bce50] cm_find_listen+0x34/0xf8 [ib_cm] Signed-off-by: David Ahern <david.ahern@oracle.com> Signed-off-by: Doug Ledford <dledford@redhat.com>
2012-07-08IB/core: Move CM_xxx_ATTR_ID macros from cm_msgs.h to ib_cm.hJack Morgenstein1-12/+0
These macros will be reused by the mlx4 SRIOV-IB CM paravirtualization code, and there is no reason to have them declared both in the IB core in the mlx4 IB driver.

2011-10-13IB/cm: Update XRC support based on XRC annex errataSean Hefty1-1/+18
The XRC annex was updated to have XRC behave more like RD. Specifically, the XRC TGT QPN moves from the local QPN to local EECN field. Lookup of SRQN is done using the REQ/REP protocol. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <roland@purestorage.com>
2011-10-13IB/cm: Update protocol to support XRCSean Hefty1-1/+12
Update the REQ and REP messages to support XRC connection setup according to the XRC Annex. Several existing fields must be set to 0 or 1 when connecting XRC QPs, and a reserved field is changed to an extended transport type.

2009-01-17IB: Remove __constant_{endian} usesHarvey Harrison1-11/+11
The base versions handle constant folding just fine, use them directly. The replacements are OK in the include/ files as they are not exported to userspace so we don't need the __ prefixed versions. This patch does not affect code generation at all. Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
2007-07-10IB/cm: cm_msgs.h should include ib_cm.hSean Hefty1-0/+1

2005-10-20[IB] cm: Add missing break in switchRoland Dreier1-0/+1
Add missing "break" in switch statement. Without the break, the CM ended up always falling through and setting every connection request to use RC transport, which meant that UC connections didn't work. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2005-08-26[PATCH] IB: move include files to include/rdmaRoland Dreier1-1/+1
Move the InfiniBand headers from drivers/infiniband/include to include/rdma. This allows InfiniBand-using code to live elsewhere, and lets us remove the ugly EXTRA_CFLAGS include path from the InfiniBand Makefiles. Signed-off-by: Roland Dreier <rolandd@cisco.com>
