Hard Release Blockers

• NONE, 10.0 has been released.

We consider the magnitude of DRM/KMS bugs (see below) as bad, but this is as good as it will realistically get for a 10.0 release.

Current status and timeline

• The netbsd-10 branch is open for pullups, there is no timeline for the 10.1 release yet.

Showstopper bugs and PRs

• Any issues found by syzbot may potentially crash the kernel and should be investigated and fixed.
• PR #55466: rump_server processes busy looping can stall a machine (regression since -9)
• PR #56329: nvme(4) takes long time to umount analyzed: the number of dirty vnodes has been bumped, no real performance regression
• autoconfig API changes need to be backed out or made type-safe see this backout request
• PR #56653: kernel crash in ipv6 fragment reassembly
• PR #56713: kqueue/kevent does not work with null mounts
• PR #55707: xcalls storm or pgdaemon high CPU consumption

Test Regressions since netbsd-9

Some of this issues are older (so "regression" is slightly wrong), but it was necessary to disable tests to not break whole test setups. This are likely effects caused by bugs in the tests or RUMP, so not considered show stoppers.

• PR #49141: lib/librumpclient/t_exec/threxec test randomly fails
• PR #50350: rump/rumpkern/t_sp/stress_{long,short} fail
• PR #55304: lib/librumpclient/t_exec/threxec, rump/rumpkern/t_sp/reconnect now fail
• PR #55356: stress_killer test case now fails on real hardware
• PR #55338: rump threxec test broken
• PR #55632: tests/net/ipsec/t_ipsec_misc: timeout tests fail randomly

Ongoing projects and unmerged branches

• Wifi renewal on hg - will not make it into mainline before the branch, but is planned to be merged into -current soon.
• Updating drmkms to Linux 5.6 - has been merged to HEAD
• Removing PF - will not happen before the branch
  • pf was deprecated in 9 so it could be removed in 10.
  • what is left to do to improve npf?
    • ftp-proxy(8) does not support npf but does support ipf and pf
    • altq(4)
    • shared rulesets ("ipf groups")?
    • address subset selection?
    • update NetBSD Guide from ipf and document migrations
    • note that most of the above are ipf things, not pf things.
    • ...
• Waiting for Randot
  • The old entropy estimator from NetBSD 9 will be revived.
  • we need to decide on how randomness would work before branch.
  • getentropy is missing from NetBSD but will be in POSIX.
  • suggested installer changes
  • rndctl(8) includes misleading features that no longer work with the current entropy behavior (disable/enable estimation, etc). it should maybe also print the number of collected samples in -l.
• File system corruption due to UFS2 extended attributes
  • NetBSD 10 will be the first official release with full extended attribute support in FFS, additional docs needed (wiki) and extensions of the install docs (pointing at wiki)
