      Warner Losh authored
      Complete the transition to README.md I started 3 years ago. Remove the
      now-redundant README file. It's currently just README.md w/o the light markup
      and adds no real value. This also allows us to use additional MarkDown
      markup as we see fit w/o worrying about keeping things in sync.

      nvme: use config_intrhook_drain to avoid removable card races · 8423f5d4
      Warner Losh authored
      nvme drives are configured early in boot. However, a number of the configuration
      steps takes which take a while, so we defer those to a config intrhook that runs
      before the root filesystem is mounted. At the same time, the PCI hot plug wakes
      up and tests the status of the card. It may decide that the card has gone away
      and deletes the child. As part of that process nvme_detach is called. If this
      call happens after the config_intrhook starts to run, but before it is finished,
      there's a race where we can tear down the device's soft state while the
      config_intrhook is still using it. Use the new config_intrhook_drain to
      disestablish the hook. Either it will be removed w/o running, or the routine
      will wait for it to finish. This closes the race and allows safe hotplug at any
      time, even very early in boot.

      config_intrhook: provide config_intrhook_drain · e5236836
      Warner Losh authored
      config_intrhook_drain will remove the hook from the list as
      config_intrhook_disestablish does if the hook hasn't been called.  If it has,
      config_intrhook_drain will wait for the hook to be disestablished in the normal
      course (or expedited, it's up to the driver to decide how and when
      to call config_intrhook_disestablish).
      This is intended for removable devices that use config_intrhook and might be
      attached early in boot, but that may be removed before the kernel can call the
      config_intrhook or before it ends. To prevent all races, the detach routine will
      need to call config_intrhook_train.

      vm_reserv: Fix list locking in vm_reserv_reclaim_contig() · 968079f2
      Mark Johnston authored
      The per-domain partpop queue is locked by the combination of the
      per-domain lock and individual reservation mutexes.
      vm_reserv_reclaim_contig() scans the queue looking for partially
      populated reservations that can be reclaimed in order to satisfy the
      caller's allocation.
      During the scan, we drop the per-domain lock.  At this point, the rvn
      pointer may be invalidated.  Take care to load rvn after re-acquiring
      the per-domain lock.
      While here, simplify the condition used to check whether a reservation
      was dequeued while the per-domain lock was dropped.

      PR:	253998
      Reported by:	rashey at superbox.pl
      MFC after:	3 days
      Loopback teardown order is `SI_SUB_INIT_IF`, which happens after `SI_SUB_PROTO_DOMAIN` (route table teardown).
      Thus, any route table operations are too late to schedule.
      As the intent of the vnet teardown procedures to minimise the amount of effort by doing global cleanups instead of per-interface ones, address this by adding a relatively light-weight routing table cleanup function, `rib_flush_routes()`.
      It removes all remaining routes from the routing table and schedules the deletion, which will happen later, when `rtables_destroy()` waits for the current epoch to finish.
      Test Plan:
      set_skip:set_skip_group_lo  ->  passed  [0.053s]
      tail -n 200 /var/log/messages | grep rtentry

      We don't need the result before next sleep time, so no reason to

      While there, remove extra PM ticks to microseconds conversion, making
      C2/C3 sleep times look 4 times smaller than really.  The conversion
      is already done by AcpiGetTimerDuration().  Now I see reported sleep
      times up to 0.5s, just as expected for planned 2 wakeups per second.

      The ENTRY() macro was modified by commit
      28d94520 to add an optional NOP instruction
      at the beginning of the function. It is of course an arm64 instruction, so
      unsuitable for the 32bits sigcode. So just use EENTRY() instead for
      aarch32_sigcode. This should fix receiving signals when running 32bits
      binaries on FreeBSD/arm64.

      ns8250: don't drop IER_TXRDY on bus_grab/ungrab · 7e7f7bee
      Mitchell Horne authored
      It has been observed that some systems are often unable to resume from
      ddb after entering with debug.kdb.enter=1. Checking the status further
      shows the terminal is blocked waiting in tty_drain(), but it never makes
      progress in clearing the output queue, because sc->sc_txbusy is high.
      I noticed that when entering polling mode for the debugger, IER_TXRDY is
      set in the failure case. Since this bit is never tracked by the softc,
      it will not be restored by ns8250_bus_ungrab(). This creates a race in
      which a TX interrupt can be lost, creating the hang described above.
      Ensuring that this bit is restored is enough to prevent this, and resume
      from ddb as expected.
      The solution is to track this bit in the sc->ier field, for the same
      lifetime that TX interrupts are enabled.

      Arch64: Clear VFP state on execve() · 953a7d7c
      Alex Richardson authored
      I noticed that many of the math-related tests were failing on AArch64.
      After a lot of debugging, I noticed that the floating point exception flags
      were not being reset when starting a new process. This change resets the
      VFP inside exec_setregs() to ensure no VFP register state is leaked from
      parent processes to children.
      This commit also moves the clearing of fpcr that was added in 65618fdd
      from fork() to execve() since that makes more sense: fork() can retain
      current register values, but execve() should result in a well-defined
      clean state.
