HAVE NEED WANT For 12.0

FreeBSD 12.0 Release action items Dependency tree

This year we didn't do a traditional Have / Need / Want, but instead listed things we're getting in to 12.0, code freeze in 2 months.

FreeBSD 12.0 Release Planning Session at BSDCan 2018 rgrimes on point to compile this into re@ actions.

What are the things to get done for 12.0 in the time allotted. [owner – driving force]

  • OpenSSL 1.1 in the base [gordon, Bernard Spil?]
    • Maybe make it a private library? A company starting with Y has had years of pain doing this… every library that uses openssl needs to be private library
    • PAM SNOWBALLS QUICKLY THERE CAN BE ONLY ONE! (Cue Queen 🎸)
  • Root CA in base? [allanjude] [Bundle the package!]
  • Move everything to ports - solved. (Does that include ports?)
  • Break bad APIs (gets(), getwd()) (keep compat symbols) [emaste]
  • Break the ABI xinpcb, etc add padding, etc [brooks, jtl]
  • Merge GELI UEFI (installer changes for this too) [imp,nathanw,allanjude, Eric McCorkle]
  • Dump bug (uninitialized variable) [imp,kirk]
  • Do we need to add a PR thing for regression / tagging PRs?
  • GCC 4.2.1 not in 12? Knife fight after this meeting to decide 50/50 [jhb]
  • PkgBase – core codebase pieces in place for 12.0 release [brd]
  • Devmatch loose ends [imp]
  • UEFI boot loader loose ends [imp]
  • Module loading penalty reduction [imp]
  • LUA loader on by default (need to hash out coexistence or not) [imp]
  • Fat MINIMAL for GENERIC? Maybe? [imp]
  • TCP stack as a module [jtl]
  • Tightening up permission on some pages in kernel memory (amd64 only) [jtl]
  • Ifconfig fooX -alias (bug) PR needed (maybe two) [dteske]
  • Build optimizations (WITH_SYSTEM_LLD, META_MODE) [bdrewery]
  • GONE IN 13 STAMPING PARTY [brooks,imp]
  • Deprecate lack of deprecation guidelines [imp]
  • EFI vt code for arm64 [manu]
  • Maybe have One Clang to Build them All (and in the process link them) during make universe [bdrewery]
  • Early microcode loading on x86 (in kernel: early boot and on resume) [markj]
  • Verified loader binary verification (opt-in) (loader loading kernel) [sjg]
  • Ficl update for boot loader [sjg,imp]
  • Speculative fixes for speculative execution (specifically ARM for latest round of issues) [speculative owner: emaste] (arm, AMD amd64)
  • List of supported boards for non-x86 (RPi0, RPi3+) [manu]
  • Cull armv6/armv7 boards [manu]
  • Generic armv7 release image + tool to add uboot to generic image. [manu]
  • 12.0 booting 2x faster to login (compared to 11.2) [cperciva]
    • Why is the boot loader taking so long [cperciva,imp]
  • Verified exec phabricator (kernel loading userland) [stevek]
  • Pkgbase include manifest for verified-exec signing (nice to have) [gordon as SO, sjg]
  • ASLR [kib]
  • NVDIMM [kib]
  • Interface for non-cached memory with userland control [not jhb]
  • Find a way to make amd64 and arm64 less confusingly similar (panic: bad peter) (DONE) 👍

FreeBSD 13

  • Firmware update tools
  • ZFS crypto
  • FreeBSD 13 known good laptops
  • Updating the Developers Handbook
  • Testing integrating into the tree (use also for qemu-user and RE)
  • CAPSICUM [jonathan] (Project Capsicum)
  • Shared expectations for things
  • DRM (arm64, all the other issues)
    • MALI images / tools
  • Native buildkernel with modules ports [jhb]
  • Integrate Peter Holm’s stress2 into the tree
  • Fix unionfs or kill it (basket of panics)
    • Investigate “Baskets of Panic” as conference schwag
    • Do any candidates for core NOT have binders full of panics?
  • NVMe rehash
  • Schedule
  • iSCSI offload
  • Multiqueue for CAM/storage (kthreads via ZFS)
  • GELI hits this too with n(cores) * n(providers) threads
  • Dexter crash dump and how to debug. network
  • Taskqueue scalability
  • Continue to prevent Peter from talking
  • Dtrace improvements (sctp providers need work)
  • ZFS RAIDZ Expansion (slides - Matt Ahrens)
  • OpenRC investigation into replacing rc.d (proposals coming – FCP and Phab)
  • Known Good Laptops on Wiki Page needs love: Laptops
    • Unique identifiers? (SMBIOS / DMI info?)
    • Look to Linux for naming problems (Why? We’ve got plenty of our own…)
    • CostcoStick (USB boot device; plug in, boot, script gathers data about hardware (then starts mining bitcoin))
  • Intel drm (socialize pkg kmod)
  • Trackpads
  • Bhyve (what to do now that Peter has moved to Apple)
    • 32-bit / 64-bit ARM
    • 3 years of GSoC code bitrotting
  • Trust Framework
  • Power9
  • RISC V
  • Power Management
  • Remove sbrk() (Emacs works finally; https://debbugs.gnu.org/cgi/bugreport.cgi?bug=24892)
  • X32 ABI
    • Compat layer for amd64
    • MIPS n32 kernel kill it with fire then pour gas on it and light it again, or to quote the great jkh: Bang! Bang! Bang! Click! Reload!! Bang! Bang!
  • 64-bit time_t i386 (x32?)
  • Merge CHERI support from cambridge
  • One crypto framework that doesn’t totally suck
  • Loader APIs for trusted (currently use slow but minimal change)
  • Remaining bits for secure boot for the using ‘buy in a store’ use case
  • TPM
  • Ipf deprecation , ipfilter, pf, ipfw (case study for deprecation policy, freebsd cluster uses pf and relies on it)
  • Unionfs isn’t totally useless
  • RPi SDIO stack (MMCCAM fleshing out – basics are in place) (kibab,imp)
  • Linux equivalent to inotify (kqueue functionally the same, but doesn’t scale as well as inotify)
  • Filesystem events
  • Coreboot experiments (Isn’t coreboot “just” an implementation of UEFI? So wouldn’t things “just work”?)
  • Food eating
  • W^X
