Can I have the ... green pointy hat, please?
- buildworld and buildkernel are built into MAKEOBJDIRPREFIX
- installworld and installkernel are performed on NANO_OBJ.
No change of functionality if MAKEOBJDIRPREFIX is not set. If it is sea,t
clean_world deletes NANO_OBJ instead of NANO_WORLDDIR. By starting nanobsd.sh
with the -b option the existing world can be reused to build a new world
reducing time and disk space considerably.
While there:
- Fix two cases where (in comments) MAKEOBJDIRPREFIX should have been
NANO_DISKIMGDIR.
- Simplify an 'if (not wrong); then true; else action; fi' into
'if wrong; then action; fi'. 'if ! false; then echo hello; fi' produces hello.
Note: Make sure you use NANO_OBJ were you use MAKEOBJDIRPREFIX now in your
nanobsd.conf files if you want to split out.
number.
It is possible to ask nanobsd.sh to create a 'data' partition,
separate from the system or configuration partitions, and
furthermore, by specifying a negative value for its size
to request that it use all space unused by those partitions
for its own size.
Because the two lines of code that calculate how much space
is available for this data partition are written in perl-like
syntax, the awk code that does the processing performs the
calculation incorrectly.
[note - this was already fixed by r174936]
Furthermore, a comparison later down fails to newfs the
partition when the size is negative.

This patch against RELENG_6 adds two more entries to
src/tools/tools/nanobsd/FlashDevice.sub - one for a 256MB
Hitachi CF card and one for a 256MB Silicon Systems CF card.
Both entries have been verified to work with a Soekris net4801.

any open file descriptors >= 'lowfd'. It is largely identical to the same
function on other operating systems such as Solaris, DFly, NetBSD, and
OpenBSD. One difference from other *BSD is that this closefrom() does not
fail with any errors. In practice, while the manpages for NetBSD and
OpenBSD claim that they return EINTR, they ignore internal errors from
close() and never return EINTR. DFly does return EINTR, but for the common
use case (closing fd's prior to execve()), the caller really wants all
fd's closed and returning EINTR just forces callers to call closefrom() in
a loop until it stops failing.
Note that this implementation of closefrom(2) does not make any effort to
resolve userland races with open(2) in other threads. As such, it is not
multithread safe.

I found out that the input format of the Boemler list was different
than what the code expected: The last two fields were interpreted
as one. Checking the csv version of the list it showed that there
was sometimes a chipset number in the column before the card

This is a rewrite to use the CSV format of the Boemler list. The
output is differently formatted: Instead of the "chip description",
it is now "description (chip)"

because it means getdelim() returns -1 for both error and EOF, and
never returns 0. However, this is what the original GNU implementation
does, and POSIX inherited the bug.

Not only did these two drivers depend on IFF_NEEDSGIANT, they were
broken 7 months ago during the MPSAFE TTY import. if_ppp(4) has been
replaced by ppp(8). There is no replacement for if_sl(4).
If we see regressions in for example the ports tree, we should just use
__FreeBSD_version 800045 to check whether if_ppp(4) and if_sl(4) are
present. Version 800045 is used to denote the import of MPSAFE TTY.

This tool creates large numbers of TCP connections, each of which will
transmit a fixed amount of data, between client and server hosts. tcpp can
use multiple workers (typically up to the number of hardware cores), and can
use multiple source IPs in order to use an expanded port/IP 4-tuple space to
avoid problems from reusing 4-tuples too quickly. Aggregate bandwidth use
will be reported after a client run.
While by no means a perfect tool, it has proven quite useful in generating
and optimizing TCP stack lock contention by easily generating high-intensity
workloads. It also proves surprisingly good at finding device driver bugs.

The function pow() in libmp(3) clashes with pow(3) in libm. We could
rename this single function, but we can just take the same approach as
the Solaris folks did, which is to prefix all function names with mp_.
libmp(3) isn't really popular nowadays. I suspect not a single
application in ports depends on it. There's still a chance, so I've
increased the SHLIB_MAJOR and __FreeBSD_version.

It is only really necessary for open(2)'s third argument, which is optional and
obtained through stdarg(3). open(2)'s third argument is 32bit and we pass 64
bits. On little endian it works, because we take lower 32 bits, but on big
endian platforms we take upper 32 bits, so we end up with 0.

allocated in a fork(2)-inheritable way at the beginning or end of an
accept(2) system call. This test creates a test thread and blocks it
in accept(2), then forks a child process which tests to see if the
next available file descriptor is defined or not (EBADF vs EINVAL for
ftruncate(2)).
This detects a regression introduced during the network stack locking
work, in which a very narrow race during which fork(2) from one
thread during accept(2) in a second thread lead to an extra inherited
file descriptor turned into a very wide race ensuring that a
descriptor was leaked into the child even though it hadn't been
returned.
