1acd87a81f First half of tty code rework: unifdef -D__FreeBSD_Version=600000
The changes in the next commit would make the code totally unreadable
if the #ifdef'ing were maintained.

It might make a lot of sense to split if_cx.c in a netgraph related
and in a tty related file but I will not attempt that without hardware.

b8c7ee4701 Fix a botched rev. 1.221 commit. Also, a number of people have
pointed out that /usr/local/etc/rc.d/000.pkgtools.sh installed
with the portupgrade does an equivalent thing, so I personally
would like to see the change reverted, but let David handle it.

a2f4d2f5b0 Limit DMA address space to 1GB since the trident audio cards can't
handle DMA addresses located above 1GB. The LBA(loop begin address)
register which holds DMA base address is 32bits register. But the
MSB 2bits are used for other purposes. This effectivly limits the
DMA address space up to 1GB.

eba1cb6e3e Audio drivers failed to detect failure condition and attempted to
assign DMA address to the wrong address. It can cause system lockup
or other mysterious errors. Since most sound cards requires low DMA
address(BUS_SPACE_MAXADDR_24BIT) sndbuf_alloc() would fail when the
audio driver is loaded after long running of operations.

d363b98e1f Permit fcntl(F_SETFL) to work on a ugen(4) device by not returning failure
for FIOASYNC.
2004-10-13 04:13:05 +00:00
Brian Feldman
601486239c Back out rev.1.91 which implemented bulk read transfers in ugen(4) as
asynchronous.  I realize that this means the custom application will
not work as written, but it is not okay to break most users of ugen(4).

The major problem is that a bulk read transfer is not an interrupt
saying that X bytes are available -- it is a request to be able to
receive up to X bytes, with T timeout, and S short-transfer-okayness.

The timeout is a software mechanism that ugen(4) provides and cannot
be implemented using asynchronous reads -- the timeout must start at
the time a read is done.

The status of up to how many bytes can be received in this transfer
and whether a short transfer returns data or error is also encoded
at least in ohci(4)'s requests to the controller.  Trying to detect
the "maximum width" results in using a single buffer of far too
small when an application requests a large read.

Even if you combat this by replacing all buffers again with the
maximal sized read buffer (1kb) that ugen(4) would allow you to
use before, you don't get the right semantics -- you have to
throw data away or make all the timeouts invalid or make the
short-transfer settings invalid.

There is no way to do this right without extending the ugen(4) API
much further -- it breaks the USB camera interfaces used because
they need a chain of many maximal-width transfers, for example, and
it makes cross-platform support for all the BSDs gratuitously hard.

Instead of trying to do select(2) on a bulk read pipe -- which has
neither the information on desired transfer length nor ability to
implement timeout -- an application can simply use a kernel thread
and pipe to turn that endpoint into something poll-able.

It is unfortunate that bulk endpoints cannot provide the same semantics
that interrupt and isochronous endpoints can, but it is possible to just
use ioctl(USB_GET_ENDPOINT_DESC) to find out when different semantics
must be used without preventing the normal users of the ugen(4) device
from working.

01c5ea585c Get rid of device nodes interface. It is useless and confusing.
The original idea was to use it for firmware upgrading and similar
operations. In real life almost all Bluetooth USB devices do not
need firmware download. If device does require firmware download
then ugen(4) (or specialized driver like ubtbcmfw(8)) should be
used instead.

2ff0e645d1 Refine the turnstile and sleep queue interfaces just a bit:
- Add a new _lock() call to each API that locks the associated chain lock
  for a lock_object pointer or wait channel.  The _lookup() functions now
  require that the chain lock be locked via _lock() when they are called.
- Change sleepq_add(), turnstile_wait() and turnstile_claim() to lookup
  the associated queue structure internally via _lookup() rather than
  accepting a pointer from the caller.  For turnstiles, this means that
  the actual lookup of the turnstile in the hash table is only done when
  the thread actually blocks rather than being done on each loop iteration
  in _mtx_lock_sleep().  For sleep queues, this means that sleepq_lookup()
  is no longer used outside of the sleep queue code except to implement an
  assertion in cv_destroy().
- Change sleepq_broadcast() and sleepq_signal() to require that the chain
  lock is already required.  For condition variables, this lets the
  cv_broadcast() and cv_signal() functions lock the sleep queue chain lock
  while testing the waiters count.  This means that the waiters count
  internal to condition variables is no longer protected by the interlock
  mutex and cv_broadcast() and cv_signal() now no longer require that the
  interlock be held when they are called.  This lets consumers of condition
  variables drop the lock before waking other threads which can result in
  fewer context switches.

6c67b8b695 When the access control on creating raw sockets was modified so that
processes in jail could create raw sockets, additional access control
checks were added to raw IP sockets to limit the ways in which those
sockets could be used.  Specifically, only the socket option IP_HDRINCL
was permitted in rip_ctloutput().  Other socket options were protected
by a call to suser().  This change was required to prevent processes
in a Jail from modifying system properties such as multicast routing
and firewall rule sets.

However, it also introduced a regression: processes that create a raw
socket with root privilege, but then downgraded credential (i.e., a
daemon giving up root, or a setuid process switching back to the real
uid) could no longer issue other unprivileged generic IP socket option
operations, such as IP_TOS, IP_TTL, and the multicast group membership
options, which prevented multicast routing daemons (and some other
tools) from operating correctly.

This change pushes the access control decision down to the granularity
of individual socket options, rather than all socket options, on raw
IP sockets.  When rip_ctloutput() doesn't implement an option, it will
now pass the request directly to in_control() without an access
control check.  This should restore the functionality of the generic
IP socket options for raw sockets in the above-described scenarios,
which may be confirmed with the ipsockopt regression test.

RELENG_5 candidate.
