utopic_tgt_1.0.43-0ubuntu5.debdiff ** Description changed:
[Impact] Trusty: * Today's libibverbs is missing important code for arm64 moonshot project. * Today's libmlx4 is missing important code for arm64 moonshot project. - Flow steering control for Openstack enablement on IPoIB - Offload support flags (for performance) * Today's tgt is suffering from the lack of iSER support (LP: #1445038). * qpid-cpp depends on ruby1.8 and should depend on ruby1.9 (LP: #1367255). Other Cases to justify such SRU: - LP: #1401575 (dup: #1445038) - iSER not working in Trusty - LP: #1445038 - TGT does not support ISER discovery - LP: #1443648 - iSER logouts cause kernel panic in 3.13 - LP: #1401141 - ISC DHCP server does not work with InfiniBand - LP: #1367255 - qpid-cpp depends on ruby1.8 and should depend on ruby1.9 Collateral Impact: - srptools - rdmacm-utils - perftest - librdmawrap2 - libopenmpi1.6 - libnes1 - libmthca1 - libmlx5-1 - libipathverbs1 - libibcm1 - libcxgb3-1 - ibverbs-utils - glusterfs-common - fio - libtotem-pg5 - librdmacm1 * libibverbs was re-factored and all rdepends should follow the ABI. * ALL SRUs should be done AT ONCE together because of ABI dependency. Utopic: - * libibverbs had offload capability added. - * libmlx4 had offload capability added. + * libibverbs had offload capability added. + * libmlx4 had offload capability added. * No ABI dependency. + + * Today's tgt is suffering from the lack of iSER support (LP: #1445038). Vivid: * [ Test Case ] * libibverbs and libmlx4 are being tested by Mellanox (who better ?) * tgt test case can be seen in LP: #1445038 * There is no support for flow steering for IB (needed) using libibverbs. * iSER is broken in Trusty (tgt and kernel - kernel addressed on other bug). Collateral Test Case: * Will test IB and iSER functionality with a PPA devoted to all these fixes. [Regression Potential] * Only for InfiniBand users who might rely on libibverbs and its rdepends. * Today's libibverbs, libmlx4, isc-dhcp and tgt (iser) have issues with IB. [Other Info] * Trusty will be fully IB compatible and fixed per Mellanox request. * Please do consider this as SRU and yes it will be big but needed. * Any doubt please contact: Rafael Tinoco <rafael.tin...@canonical.com> ORIGINAL BUG DESCRIPTION: Mellanox is requesting Canonical and Ubuntu Community for some patches to be backported from upstream to libibverbs and libmlx4 in order to have their HW proper supported in Trusty, Utopic and Vivid. There are in charge of testing those packages and providing proper verification.
