Changed content

cam-cdrom.so, cam-disk.so, cam-optical.so

We've documented the retries, timeout, and verbose options.

The maximum number of threads that you can specify with the -t option has increased from 4 to 100.

devn-*

We've added some information about hardware checksumming.

We've documented the pauseignore and pausesuppress options and updated the default values for the receive and transmit options.

devn-speedo.so

We've added the probe_phy option, which you can use to enable or disable the probing of the PHY device.

df

This utility rounds its figures into 512- or 1024-byte blocks (depending on the options), and it always rounds down. If the filesystem doesn't use a block size that's a multiple of 512 bytes, some rounding errors will occur.

dinit

We recommend that you use dinit to initialize a QNX 4 filesystem, and dloader to make it bootable. The dinit bootloader options are for backwards compatibility reasons, but aren't generally used anymore.

dumper

There's a new -z option that makes dumper compress the core files.

enum-devices

The start, requires, and driver clauses now support a /wait option that makes the enumerator pause until the command associated with the clause terminates.
The macro for starting core networking is now IOPKT_CMD.

flashctl

There's now a section that describes the information that's displayed if you specify the -i option.

fs-cd.so

We've added these options:

case — control how ISO-9660 filenames should be displayed. The case option can now have a value of asis.
exe — set execute permission (on all non-RRIP regular files).
nohsf — disable High Sierra format.

fs-dos.so

The following options have changed:

case — new
codepage — these names are also used for the volume label
compat — supports a value of os2
fat — new

fs-etfs-ram

An ETFS filesystem is no longer mounted by default; you can use the -m option or mount -tetfs /dev/etfs2 my_mountpoint.

fs-qnx4.so

We've added the following options:

bitmap — when to pre-read .bitmap files.
grown — allow persistent over-grown files (sticky O_APPEND allocation).

Note: We've deprecated the rmvbmap option; it's equivalent to bitmap=always.

ftp, ftpd

We now use the NetBSD 4.0 version of these programs, although ftpd also supports the -n option that was added after version 4.0.

gzip

You can now use gzip to compress or expand files in a RAM filesystem (/dev/shmem), but you need to specify the -f option.

ifconfig

Updated to work with io-pkt*.

io-blk.so

The alloc option now specifies an allocation mode instead of an amount of memory to allocate.
The default values of the following options have changed:
- bufsz — now 512:8K
- fdinfo — now always
- thread — now 12:2:5
The optional level argument to the verbose option indicates which categories of events to log.
We've added the marking option.

ksh

You can now use the Tab key to complete the names of files and commands.

mkifs

We've added the cpu modifier to the description of script files.
The /usr/lib/ldqnx.so.2 symbolic link should now point to /proc/boot/libc.so.3, and you should include libc.so.2 in the list of binaries before libc.so.
The documentation now describes the -s option and the +|-page_align attribute.
We've updated the default linker specification.

mount

We've documented the -a option.

mq

The /dev/mq directory doesn't appear until you actually create a queue.

mqueue

The /dev/mqueue directory doesn't appear until you actually create a queue.

nicinfo

This utility has been updated to work with io-pkt*.

The documentation now describes the -c, -g, and -s options.

pidin

We've added more details about the information that the fds shorthand gives.

ping

This utility has been updated to work with io-pkt*.

If a name server isn't responding, there's a timeout of 1.5 minutes per name server.

pppd

For information about this daemon (including exit codes), see the NetBSD documentation. We've documented the options that are specific to Neutrino.

procnto*

If you're using an SMP version of procnto, you can use the appropriate startup-* command's -P option to specify the maximum number of CPUs to activate.
There's a new procnto-v6 version of the kernel that supports ARMv6 processors.
There are new procnto-900 and procnto-900-smp versions of the kernel that support PowerPC 900 series processors.
New options:
- -en and -eo — control the value of EALREADY, which is changing so that it will be POSIX-compliant. For more information, see "Changes to EALREADY" in the entry for errno in the Neutrino C Library Reference.
- -mP — turn on full allocation of high memory for all processes. This is mostly useful only for testing.
- -m~P — make sure that all anonymous allocation occurs below the 4 GB mark (the default).
- -m[~]v — enable or disable variable page sizes. They're enabled by default.
- -m[~]x — enable or disable the PROT_EXEC flag for system-allocated threads. It's enabled by default.
- -T — specify the number of seconds to wait for a close() to succeed in the event of process termination.
- -u — specify the umask to use when creating the entries in /proc/pid/as.

qcc

The -M option to qcc isn't changing to -Map as we warned in earlier releases; qcc continues to use -M for generating a mapfile.

qconfig

This utility doesn't list the installed packages in any particular order.

qde

We no longer ship the Neutrino-hosted IDE, so qde now runs only on Linux and Windows development hosts.

random

This utility creates /dev/urandom as well as /dev/random.

rtsold

This daemon now has an -a option that lets you autoprobe the outgoing interface.

ruptime, rwho, rwhod

The data files that these programs use are now in /var/rwho instead of /usr/spool/rwho, to conform to the Filesystem Hierarchy Standard.

rwhod

This daemon now has -i and -u options for setting the broadcast interval and the user to run as.

setkey

Updated to work with io-pkt*.

slay

If you change the runmask for a process, the processor for blocked threads doesn't change until the threads become unblocked (or never if the threads remain blocked).

slogger

There's a new -c option that you can use to open the log file with O_SYNC to forcibly commit the logged events to the disk.

sysctl

The available variables depend on what you're running on your machine; we've described the ones that you're most likely to be interested in.

tftpd

We now use the NetBSD 3.0 version of this daemon, so the options have changed.

tinit

We've added the -f and -t options.
We've described the way that tinit parses its configuration file.

which

We've added the -s option, which makes the utility search for shared objects in the directories identified by the LD_LIBRARY_PATH environment variable and the _CS_LIBPATH configuration string.
