Yaroslav Tykhiy 252b6fe8b2 Define the target for opt_compat.h only if KERNBUILDDIR
is not defined, so that the module will get the
compatibility options from the current kernel configuration
if built with the latter, not with the world.
[Some other modules seem in need of fixing WRT this, too.]

Add more compatibility options found in GENERIC to the default
opt_compat.h.  While not all of them are used in the procfs code,
we can't tell for sure if the system .h files don't need them either,
so let's stay on the safe side.

Maxim Sobolev 536fde3465 In re_shutdown() mark interface as down since otherwise we will panic if
interrupt comes in later on, which can happen in some uncommon cases.

Another possible fix is to call re_detach() instead of re_stop(), like
ve(4) does, but I am not sure if the latter is really RTTD, so that stick
with this one-liner for now.

This is actually a local DoS, as every user can use /dev/crypto if there

Gleb Smirnoff 1ae954096e In order to support CARP interfaces kernel was taught to handle more
than one interface in one subnet. However, some userland apps rely on
the believe that this configuration is impossible.

Add a sysctl switch net.inet.ip.same_prefix_carp_only. If the switch
is on, then kernel will refuse to add an additional interface to
already connected subnet unless the interface is CARP. Default
value is off.

Ian Dowse 4832a19173 Add a "comconsole_speed" loader variable that can be used to change
the serial console speed (i386 and amd64 only). If the previous
stage boot loader requested a serial console (RB_SERIAL or RB_MULTIPLE)
then the default speed is determined from the current serial port
speed. Otherwise it is set to 9600 or the value of BOOT_COMCONSOLE_SPEED
at compile time.

This makes it possible to set the serial port speed once in
/boot.config and the setting will propagate to boot2, loader and
the kernel serial console.
2005-08-18 01:39:43 +00:00
Ian Dowse a00a259113 Add the ability to specify the boot2 serial console speed in
/boot.config or on the "boot:" prompt line via a "-S<speed>" flag,
e.g. "-h -S19200". This adds about 50 bytes to the size of boot2
and required a few other small changes to limit the size impact.
This changes only affects boot2; there are further loader changes
to follow.

- Add locked variants of el_init and el_start.
- Don't initialize the mutex and lock it during el_probe().
- Do initialize the mutex during attach.  (el_probe() did destroy the mutex
  to cleanup, so this meant the driver was always using a destroyed mutex
  when it was running.)
- Setup the interrupt handler after ether_ifattach().
- Fix locking in el_detach() and el_ioctl().

Christian S.J. Peron 8677689134 Ensure that file flags such as schg, sappnd (and others) are honored
by md(4). Before this change, it was possible to by-pass these flags
by creating memory disks which used a file as a backing store and
writing to the device.

This was discussed by the security team, and although this is problematic,
it was decided that it was not critical as we never guarantee that root will
be restricted.

This change implements the following behavior changes:

-If the user specifies the readonly flag, unset write operations before
 opening the file. If the FWRITE mask is unset, the device will be
 created with the MD_READONLY mask set. (readonly)
-Add a check in g_md_access which checks to see if the MD_READONLY mask
 is set, if so return EROFS
-Do not gracefully downgrade access modes without telling the user. Instead
 make the user specify their intentions for the device (assuming the file is
 read only). This seems like the more correct way to handle things.

This is a RELENG_6 candidate.

Marius Strobl 1b279bfb52 - Change the code that determines whether to use a serial console and
which serial device to use in that case respectively to not rely on
  the OFW names of the input/output and stdin/stdout devices. Instead
  check whether input and output refers to the same device and is of
  type serial (uart(4) was already doing this) and for the fallback
  to a serial console in case a keyboard is the selected input device
  but unplugged do the same for stdin and stdout in case the input
  device is nonexistent (PS/2 and USB keyboards) or has a 'keyboard'
  property (RS232 keyboards). Additionally also check whether the OFW
  did a fallback to a serial console in the same way in case the
  output device is nonexistent. While at it save on some variables
  and for sys/boot/sparc64/loader/metadata.c move the code in question
  to a new function md_bootserial() so it can be kept in sync with
  uart_cpu_getdev_console() more easily.
  This fixes selecting a serial console and the appropriate device
  when using a device path for the 'input-device' and 'output-device'
  OFW environment variables instead of an alias for the serial device
  to use or when using a screen alias that additionally denotes a
  video mode (like e.g. 'screen:r1024x768x60') but no keyboard is
  plugged in (amongst others). It also makes the code select a serial
  console in case the OFW did the same due to a misconfiguration like
  both 'input-device' and 'output-device' set to 'keyboard' or to a
  nonexisting device (whether the OFW does a fallback to a serial
  console in case of a misconfiguration or one ends up with just no
  console at all highly depends on the OBP version however).
- Reduce the size of buffers that only ever need to hold the string
  'serial' accordingly. Double the size of buffers that may need to
  hold a device path as e.g. '/pci@8,700000/ebus@5/serial@1,400000:a'
  exceeds 32 chars.
- Remove the package handle of the '/options' node from the argument
  list of uart_cpu_getdev_dbgport() as it's unused there and future
  use is also unlikely.
