From there network drivers can esily use it without caring about

Only generate a new xid at the start of getting a new lease.

"RFC 2131 4.1 Constructing and sending DHCP messages" has this:

| Selecting a new 'xid' for each retransmission is an implementation
| decision.  A client may choose to reuse the same 'xid' or select a new
| 'xid' for each retransmitted message.

We used to change xid for each request / response cycle but this ran
into problems with slow dhcp servers where we would change the xid too
frequently and would ignore late coming replies from the server.

Andre S points out that table 5 in "4.4.1 Initialization and
allocation of network address" says for the xid field in "DHCPREQUEST"
messages:

| 'xid' from server DHCPOFFER message

This seems to suggest that we need to use the same xid for the whole
DHCPDISCOVER / DHCPOFFER / DHCPREQUEST / DHCPACK exchange of messages.

Nothing else in the RFC is saying this though.

But since there are DHCP servers out there that depend on this, we
only generate a new xid when entering the INIT, REBOOTING and RENEWING
state.

I do wonder if we should just go with a static value of 0x04, which
was chosen by a fair dice roll, so guaranteed to be random.

Use `sb_mtx' instead of `inp_mtx' in receive path for inet sockets.

In soreceve(), we only touch `so_rcv' socket buffer, which has it's own
`sb_mtx' mutex(9) for protection. So, we can avoid solock() in this
path - it's enough to hold `sb_mtx' in soreceive() and around
corresponding sbappend*(). But not right now :)

This time we use shared netlock for some inet sockets in the soreceive()
path. To protect `so_rcv' buffer we use `inp_mtx' mutex(9) and the
pru_lock() to acquire this mutex(9) in socket layer. But the `inp_mtx'
mutex belongs to the PCB. We initialize socket before PCB, tcp(4)
sockets could exist without PCB, so use `sb_mtx' mutex(9) to protect
sockbuf stuff.

This diff mechanically replaces `inp_mtx' by `sb_mtx' in the receive
path. Only for sockets which already use `inp_mtx'. All other sockets
left as is. They will be converted later.

Since the `sb_mtx' is optional, the new SB_MTXLOCK flag introduced. If
this flag is set on `sb_flags', the `sb_mtx' mutex(9) should be taken.
New sb_mtx_lock() and sb_mtx_unlock() was introduced to hide this check.
They are temporary and will be replaced by mtx_enter() when all this
area will be converted to `sb_mtx' mutex(9).

Also, the new sbmtxassertlocked() function introduced to throw
corresponding assertion for SB_MTXLOCK marked buffers. This time only
sbappendaddr() calls it. This function is also temporary and will be

8 months agodt(4): move interval/profile entry points to dedicated clockintr callback
cheloha [Fri, 9 Feb 2024 17:42:18 +0000 (17:42 +0000)]
dt(4): move interval/profile entry points to dedicated clockintr callback

To improve the utility of dt(4)'s interval and profile probes we need
to move the probe entry points from the fixed-frequency hardclock() to
a dedicated clock interrupt callback so that the probes can fire at
arbitrary frequencies.

- Remove entry points for interval/profile probes from hardclock().

- Merge dt_prov_profile_enter(), dt_prov_interval_enter(), and
  dt_prov_profile_fire() into one function, dt_clock().  This is
  the now-unified callback for interval/profile probes.  dt_clock()
  will consume multiple events during a single execution if it is
  delayed, but on platforms with high quality interrupt clocks this
  should be rare.

- Each struct dt_pcb gets its own clockintr handle, dp_clockintr.

- In struct dt_pcb, replace dp_maxtick/dp_nticks with dp_nsecs,
  the PCB's sampling period.  Aynchronous probes must initialize
  dp_nsecs to a non-zero value during dtpv_alloc().

- In struct dt_pcb, replace dp_cpuid with dp_cpu so that
  dt_ioctl_record_start() knows where to bind the PCB's
  dp_clockintr.

- dt_ioctl_record_start() binds, staggers, and starts all
  interval/profile PCBs on the given dt_softc.  Each dp_clockintr
  is given a reference to its enclosing PCB so that dt_clock()
  doesn't need to search for it.  The staggering sort-of simulates
  the current behavior under hardclock().

- dt_ioctl_record_stop() unbinds all interval/profile PCBs.  The
  CL_BARRIER ensures that dp_clockintr's PCB reference is not in
  use by dt_clock() so that the PCB may be safely freed upon
  return from dt_ioctl_record_stop().  Blocking while holding
  dt_lock is not ideal, but in practice blocking in this spot is
  rare and dt_clock() completes quickly on all but the oldest
  hardware.  An extremely unlucky thread could block for every
  interval/profile PCB on the softc, but this is implausible.

DT_FA_PROFILE values are up-to-date for amd64, i386, and macppc.
Somebody with the right hardware needs to check-and-maybe-fix the
values on octeon, powerpc64, and sparc64.

8 months agoclockintr: add clockintr_unbind()
cheloha [Fri, 9 Feb 2024 16:52:58 +0000 (16:52 +0000)]
clockintr: add clockintr_unbind()

The clockintr_unbind() function cancels any pending execution of the
given clock interrupt object's callback and severs the binding between
the object and its host CPU.  Upon return from clockintr_unbind(), the
clock interrupt object may be rebound with a call to clockintr_bind().

The optional CL_BARRIER flag tells clockintr_unbind() to block if the
clockintr's callback function is executing at the moment of the call.
This is useful when the clockintr's arg is a shared reference and the
caller needs to be certain the reference is inactive.

Now that clockintrs can be bound and unbound repeatedly, there is more
room for error.  To help catch programmer errors, clockintr_unbind()
sets cl_queue to NULL.  Calls to other API functions after a clockintr
is unbound will then fault on a NULL dereference.  clockintr_bind()
also KASSERTs that cl_queue is NULL to ensure the clockintr is not
already bound.  These checks are not perfect, but they do catch some
common errors.
