with the INTR_FILTER-enabled MI code. Basically this consists of
registering an interrupt controller (of which there can be multiple
and optionally different ones either per host-to-foo bridge or shared
amongst host-to-foo bridges in any one machine) along with an interrupt
vector as specific argument for all the interrupt vectors used by a
given host-to-foo bridge (roughly similar to registering interrupt
sources on amd64 and i386), providing functions to enable, clear and
disable the interrupts of the children beneath the bridge.
This also includes:
- No longer entering a critical section in tl0_intr() and tl1_intr()
for executing interrupt handlers but rather let the handlers enter
it themselves so in the case of intr_event_handle() we don't enter
a nested critical section.
- Adding infrastructure for binding delivery of interrupt vectors to
specific CPUs which later on can be interfaced with the code from
amd64/i386 for binding interrupts to specific CPUs.
- Getting rid of the wrapper hack introduced along the lines of the
API changes for INTR_FILTER which as a side-effect caused interrupts
associated with ithread handlers only to get the elevated priority
of those associated with filters ("fast handlers") (this removes the
hack also in the non-INTR_FILTER case).
- Disabling (by not clearing) an interrupt in the interrupt controller
until all associated handlers have been executed, which is crucial
for the typical locking strategy of NIC drivers in order to work
correctly in case of shared interrupts. This was a more or less
theoretical problem on sparc64 though, as shared interrupts are
rather uncommon there except for the on-board SCCs and UARTs.
Note that due to the behavior of at least of some of the interrupt
controllers used on sparc64 an enable+EOI instead of a disable+EOI
approach (as implied by the INTR_FILTER MI code and implemented on
other architectures) is used as the latter can cause lost interrupts
or in the worst case interrupt starvation.
o Correct a typo in sbus_alloc_resource() which caused (pass-through)
allocations to only work down to the grandchildren of the bus, which
wasn't a real problem so far as we don't support any devices which are
great-grandchildren or greater of a U2S bridge, yet.
o In fhc(4) use bus_{read,write}_4() instead of bus_space_{read,write}_4()
in order to get rid of sc_bh and sc_bt in the fhc_softc. Also get rid
of some other unneeded members in fhc_softc.

The first drop was Beta, this code is expected to be the release version.
Note that this driver code will build in either 6.2 or 7. If you
use the code in 6.2 you will not get TSO or MSI/X support but it will
function in a legacy mode.

used, rather than the one passed via 'req', which may not reflect a
rewrite. This call to useracc() is redundant to validation performed by
later copyin()/copyout() calls, so there isn't a security issue here,
but this could technically lead to excessive validation of addresses if
the length in newlen is shorter than req.newlen.

can easily block in bread(), and then there was nothing to prevent the
static buffer (nambuf_{ptr,len,last_id}) being clobbered by another
thread.
The effects of the bug seem to have been limited to failed lookups and
mangled names in readdir(), since Giant locking provides enough
serialization to prevent concurrent calls to the functions that access
the buffer. They were very obvious for multiple concurrent tree walks,
especially with a small cluster size.
The bug was introduced in msdosfs_conv.c 1.34 and associated changes,
and is in all releases starting with 5.2.
The fix is to allocate the buffer as a local variable and pass around
pointers to it like "_r" functions in libc do. Stack use from this
is large but not too large. This also fixes a memory leak on module
unload.

the callout_lock spin lock and the sleepqueue spin locks. In the fix,
callout_drain() has to drop the callout_lock so it can acquire the
sleepqueue lock. The state of the callout can change while the
callout_lock is held however (for example, it can be rescheduled via
callout_reset()). The previous code assumed that the only state change
that could happen is that the callout could finish executing. This change
alters callout_drain() to effectively restart and recheck everything
after it acquires the sleepqueue lock thus handling all the possible
states that the callout could be in after any changes while callout_lock
was dropped.
