* ibcore: Fix an array index checkSlava Shwartsman2018-12-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | The array ib_mad_mgmt_class_table.method_table has MAX_MGMT_CLASS (80) elements. Hence compare the array index with that value instead of with IB_MGMT_MAX_METHODS (128). This patch avoids that Coverity reports the following: Overrunning array class->method_table of 80 8-byte elements at element index 127 (byte offset 1016) using index convert_mgmt_class(mad_hdr->mgmt_class) (which evaluates to 127).

* Introduce and use sgid_index in CM requests in ibcore.Hans Petter Selasky2018-09-095-10/+57
| | | | | | | | | | | | | | | | | | | | | | For RoCE, when CM requests are received for RC and UD connections, netdevice of the incoming request is unavailable. Because of that CM requests are always forwarded to init_net namespace. Now that we have the GID index available, introduce SGID index in incoming CM requests and refer to the netdevice of it. While at it fix some incorrect uses of init_net and make sure the rdma_create_id() function stores the VNET it is passed.

* ibcore: Fix endless loop in searching for matching VLAN deviceSlava Shwartsman2018-09-061-2/+2
| | | | | | | | | | | | | | | | In r337943 ifnet's if_pcp was set to the PCP value in use instead of IFNET_PCP_NONE. Current ibcore code assumes that if_pcp is IFNET_PCP_NONE with VLAN interfaces so it can identify prio-tagged traffic.

* Check AF family prior resolving address and introduce safer rdma_addr_size() ↵Hans Petter Selasky2018-07-173-13/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | variants in ibcore. Garbage supplied by user will cause to UCMA module provide zero memory size for memcpy(), because it wasn't checked, it will produce unpredictable results in rdma_resolve_addr(). There are several places in the ucma ABI where userspace can pass in a sockaddr but set the address family to AF_IB. When that happens, rdma_addr_size() will return a size bigger than sizeof struct sockaddr_in6, and the ucma kernel code might end up copying past the end of a buffer not sized for a struct sockaddr_ib. Fix this by introducing new variants int rdma_addr_size_in6(struct sockaddr_in6 *addr); int rdma_addr_size_kss(struct __kernel_sockaddr_storage *addr); that are type-safe for the types used in the ucma ABI and return 0 if the size computed is bigger than the size of the type passed in. We can use these new variants to check what size userspace has passed in before copying any addresses.

| | | | | | | | | | | | | | | | | | | | Prior to access UCMA commands, the context should be initialized and connected to CM_ID with ucma_create_id().

* Add support for prio-tagged traffic for RDMA in ibcore.Hans Petter Selasky2018-07-173-7/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | When receiving a PCP change all GID entries are reloaded. This ensures the relevant GID entries use prio tagging, by setting VLAN present and VLAN ID to zero. The priority for prio tagged traffic is set using the regular rdma_set_service_type() function. Fake the real network device to have a VLAN ID of zero when prio tagging is enabled. This is logic is hidden inside the rdma_vlan_dev_vlan_id() function which must always be used to retrieve the VLAN ID throughout all of ibcore and the infiniband network drivers. The VLAN presence information then propagates through all of ibcore and so incoming connections will have the VLAN bit set. The incoming VLAN ID is then checked against the return value of rdma_vlan_dev_vlan_id(). MFC after: 1 week Sponsored by: Mellanox Technologies Notes: svn path=/head/; revision=336372

* For multicast functions in ibcore, verify that LIDs are multicast LIDs.Hans Petter Selasky2018-07-171-2/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | The Infiniband spec defines "A multicast address is defined by a MGID and a MLID" (section 10.5). Add check to verify that the MLID value is in the correct address range. RoCE Annex (A16.9.10/11) declares that during attach (detach) QP to a multicast group, if the QP is associated with a RoCE port, the multicast group MLID is unused and is ignored. During attach or detach multicast, when the QP is associated with a port, it is enough to check the port's link layer and validate the LID only if it is Infiniband. Otherwise, avoid validating the multicast LID.

When the multicast detach is called, the list is searched, and regardless of the search outcome, the driver detach is called. If an MGID/MLID pair is not on the list, driver detach should not be called, and an error should be returned. Calling the driver without removing an MGID/MLID pair from the list can leave the core and driver out of sync.

* Add lock to multicast handlers in ibcore.Hans Petter Selasky2018-07-172-2/+9
| | | | | | | | | | | | | | | | | | | | | | | When two handlers used the same object in the old schema, we blocked the process in the kernel. The new schema just returns -EBUSY. This could lead to different behaviour in applications between the old schema and the new schema. In most cases, using such handlers concurrently could lead to crashing the process. For example, if thread A destroys a QP and thread B modifies it, we could have the destruction happens before the modification. In this case, we are accessing freed memory which could lead to crashing the process. This is true for most cases. However, attaching and detaching a multicast address from QP concurrently is safe. Therefore, we preserve the original behaviour by adding a lock there.

* Only update source address when resolving is successful in ibcore.Hans Petter Selasky2018-07-171-11/+20
| | | | | | | | | | | | | | | | | | | When resolving an IP address in ibcore, only update the source address upon normal completion. The ibcore address resolve function does not care about the scope ID value of the IPv6 link-local addresses and expects this information has already been extracted into the bound_dev_if field. Because the same IPv6 link-local address can exist on multiple interfaces the ibcore address resolver gets confused and returns ENETUNREACH. Instead of updating both source address and bound_dev_if just keep the address set to any address until resolving completes. For the sake of code symmetry a similar change has been applied to the IPv4 address resolve path. MFC after: 1 week Sponsored by: Mellanox Technologies Notes: svn path=/head/; revision=336364

When the host receiving 64 streams of netperf -H $DUT -t UDP_STREAM -- -m 1, I see, using nstat -I mce0 1 before the patch: InMpps OMpps InGbs OGbs err TCP Est %CPU syscalls csw irq GBfree 4.98 0.00 4.42 0.00 4235592 33 83.80 4720653 2149771 1235 247.32 4.73 0.00 4.20 0.00 4025260 33 82.99 4724900 2139833 1204 247.32 4.72 0.00 4.20 0.00 4035252 33 82.14 4719162 2132023 1264 247.32 4.71 0.00 4.21 0.00 4073206 33 83.68 4744973 2123317 1347 247.32 4.72 0.00 4.21 0.00 4061118 33 80.82 4713615 2188091 1490 247.32 4.72 0.00 4.21 0.00 4051675 33 85.29 4727399 2109011 1205 247.32 4.73 0.00 4.21 0.00 4039056 33 84.65 4724735 2102603 1053 247.32 After the patch InMpps OMpps InGbs OGbs err TCP Est %CPU syscalls csw irq GBfree 5.43 0.00 4.20 0.00 3313143 33 84.96 5434214 1900162 2656 245.51 5.43 0.00 4.20 0.00 3308527 33 85.24 5439695 1809382 2521 245.51 5.42 0.00 4.19 0.00 3316778 33 87.54 5416028 1805835 2256 245.51 5.42 0.00 4.19 0.00 3317673 33 90.44 5426044 1763056 2332 245.51 5.42 0.00 4.19 0.00 3314839 33 88.11 5435732 1792218 2499 245.52 5.44 0.00 4.19 0.00 3293228 33 91.84 5426301 1668597 2121 245.52 Similarly, netperf reports 230Mb/s before the patch, and 270Mb/s after the patch Reviewed by: gallatin Sponsored by: Limelight Networks Differential Revision: https://reviews.freebsd.org/D15366 Notes: svn path=/head/; revision=333813
