We propose that the goal for a new design should be to free cloud tenants entirely from having to build and operate virtual networks. Building on this philosophy, we propose that instead of low-level building blocks (virtual links, routers, firewalls), cloud networking should be exposed to tenants in a declarative and endpoint-centric manner.","PeriodicalId":224944,"journal":{"name":"Proceedings of the Workshop on Hot Topics in Operating Systems","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130054575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ensuring consistency between them is a source of significant developer effort, yet still a source of significant bugs in mature applications. We present the Aurora single level store (SLS), an OS that simplifies persistence by automatically persisting all traditionally ephemeral application state. With recent storage hardware like NVMe SSDs and NVDIMMs, Aurora is able to continuously checkpoint entire applications with millisecond granularity. Aurora is the first full POSIX single level store to handle complex applications ranging from databases to web browsers. Moreover, by providing new ways to interact with and manipulate application state, it enables applications to provide features that would otherwise be prohibitively difficult to implement. We argue that this provides strong evidence that manipulation and persistence of application state naturally belong in an operating system.","PeriodicalId":224944,"journal":{"name":"Proceedings of the Workshop on Hot Topics in Operating Systems","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123195920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, metastable failures manifest themselves as black swan events; they are outliers because nothing in the past points to their possibility, have a severe impact, and are much easier to explain in hindsight than to predict. Although instances of metastable failures can look different at the surface, deeper analysis shows that they can be understood within the same framework. We introduce a framework for thinking about metastable failures, apply it to examples observed during years of operating distributed systems at scale, and survey ad-hoc techniques developed post-factum for making systems resilient to known metastable failures. A systematic approach for building systems that are robust against unknown meta-stable failures remains an open problem.","PeriodicalId":224944,"journal":{"name":"Proceedings of the Workshop on Hot Topics in Operating Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126795054","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ten years have passed. We now live in a post-x86 world where servers are no longer homogeneous.

Many data centers have launched large scales of customized ASICs (e.g., Google TPU [8], AWS Nitro [1]). At the same time, HBM and NVM are promised to change the landscape of memory and storage; various programmable networking devices like SmartNIC and programmable switches are making their ways into data centers. These exciting new hardware trends have driven systems researchers to innovate on software to fit new hardware technologies.

However, allowing applications to circumvent the kernel makes it impossible to use tools (e.g., tcpdump) or impose policies (e.g., QoS and filters) that need to interpose on traffic sent by different applications running on a host. This makes maintainability and manageability a challenge for kernel-bypass applications. In response, we propose Kernel On-Path Interposition (KOPI), in which traditional kernel data-plane functionality is retained but implemented in a fully programmable SmartNIC. We hypothesize that KOPI can support the same tools and policies as the kernel stack while retaining the performance benefits of kernel bypass.","PeriodicalId":224944,"journal":{"name":"Proceedings of the Workshop on Hot Topics in Operating Systems","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115036318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, data serialization obviates the benefits of zero-copy I/O, because it requires the CPU to read, transform, and write message data, resulting in additional memory copies between the real object instances and the contiguous socket buffer. Therefore, we argue for offloading serialization logic to the DMA path via specialized hardware. We propose an initial hardware design for such an accelerator, and give preliminary evidence of its feasibility and expected benefits.","PeriodicalId":224944,"journal":{"name":"Proceedings of the Workshop on Hot Topics in Operating Systems","volume":"118 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121453274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Modern OS kernels like Linux are based on traditional MMUs and have no clear abstractions to represent this complexity, mostly leaving IOMMU configuration to device drivers. This has led to a recent spate of serious bugs, and increasing concern over \"cross-SoC\" attacks on memory security. To address this, we propose a new kernel primitive, mmapx, based on a decoding net a rich and detailed representation of the memory addressing semantics of a complex SoC from the recent formal methods literature. mmapx provides a uniform facility for securely configuring all the address translation facilities in a system. mmapx leverages existing Unix facilities wherever possible: the file system for naming, discovery, and coarse-grained access control, and file descriptors for fine-grained authorization. We show how mmapx can eliminate bugs caused by device drivers programming IOMMUs directly, but also the detail captured by the underlying model has further benefits while incurring minimal overhead.","PeriodicalId":224944,"journal":{"name":"Proceedings of the Workshop on Hot Topics in Operating Systems","volume":"106 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115550996","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
