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
