mixture of a union and a double in an expression (imagine that!)
I see other similar uses, and how they pass through for other ports
is beyond me, but I have not touched them in this round.

parse quota plists; as well as a getfsquota() function to retrieve quotas
for a single id from a single filesystem (whatever filesystem this is:
a local quota-enabled fs or NFS). This is build on functions getufsquota()
(for local filesystems with UFS-like quotas) and getnfsquota();
which are also available to userland programs.
move functions from quota2_subr.c to libquota or libprop as appropriate,
and ajust in-tree quota tools.
move some declarations from kernel headers to either sys/quota.h or
quota/quota.h as appropriate. ufs/ufs/quota.h still installed because
it's needed by other installed ufs headers.
ufs/ufs/quota1.h still installed as a quick&dirty way to get a code
using the old quotactl() to compile (just include ufs/ufs/quota1.h instead of
ufs/ufs/quota.h - old code won't compile without this change and this is
on purpose).
Discussed on tech-kern@ and tech-net@ (long thread, but not much about
libquota itself ...)
SYNOPSIS to the description of the functions.
* Use .Ss for non-standard subtitles.
* Fix two identical subtitles.
* Add missing .It's, fix few .Ft's.
* Use a little more markup.
* Improve offsets.
initialisation order is correct in this case as _lwp_setprivate has been
called already by ld.elf_so for dynamic programs or _libc_init for
statically linked ones.
count. Remove now unused GETVECWORDn macro.
This is needed to make it work on alpha which use non-standard 64bit
values for the symbol hash table section, unlike all other archs.
- no need for all the weak symbols
- define a new _VIS_END flag for UNVIS_END so that there are no collisions
between and vis and unvis flags.
- add bound versions of the vis and unvis functions that take the length of
the destination buffer. Unlike the OpenBSD ones they return -1 or NULL if
the buffer is not large enough, instead of silently truncating.
init. Otherwise powerpc dlsym() DTWT and returns NULL.
(now i have no idea why dlsym() it works from rcinit(), but i'll
opt to not care)
Hah, only took 15min to debug that crap this time around. I'm
quickly approaching zero-time with it.
_rtld_tls_allocate and _rtld_tls_free. libpthread uses this functions to
setup the thread private area of all new threads. ld.elf_so is
responsible for setting up the private area for the initial thread.
Similar functions are called from _libc_init for static binaries, using
dl_iterate_phdr to access the ELF Program Header.
Add test cases to exercise the different TLS storage models. Test cases
are compiled and installed on all platforms, but are skipped on
platforms not marked for TLS support.
This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.
It is inspired by the TLS support in FreeBSD by Doug Rabson and the
clean ups of the DragonFly port of the original FreeBSD modifications.
Fixes floating point exceptions in _longjmp() during /etc/rc and
now NWS-3470D boots up to multi user with -current userland binaries.
Also fill BDslots in error path properly.
now possible to use unmodified userspace binaries (rpcbind, mountd,
nfsd) to start a rump nfs service and mount file systems from it.

rumpfs on / type rumpfs (local)
10.1.1.1:/export on /mnt type nfs
_not_ get removed if the call goes to the rump namespace.
So, now it's possible to use e.g. tcpdump (and most other utilities
which hardcore a /dev pathname) on a rump kernel:
golem> setenv RUMPHIJACK blanket=/dev/bpf
golem> tcpdump -n -i virt0
tcpdump: WARNING: SIOCGIFADDR: virt0: Device not configured
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on virt0, link-type EN10MB (Ethernet), capture size 96 bytes

21:55:39.095596 IP 204.152.190.12 > 192.168.2.101: ICMP echo reply, id 47811, seq 0, length 64
(if you additionally set socket=all in RUMPHIJACK, tcpdump doesn't
whine about the "not configured" interface)
slightly better in the multithreaded exec case in terms of partial
frames sent. Plus, it's theoretically a little cheaper.
There's still a gray area with partial transfer from sendmsg(),
but I'm not sure I care enough about some academic scenario to
start fixing it (it basically needs an OOB exec signaller).
the exec handshake to return.
In addition to being The Right Thing To Do, fixes some nasty
conditions for CLOEXEC fd's (or at least does so in theory, I
couldn't create any problems although I tried).
subdirectories.
Also, bsd.lib.mk requires a defined LIB, otherwise it will generate
unwanted commands during clean. It even failed on netbsd-4 where
'rm -f' needs at least one parameter which is missing due to recent
corrections in make/vars.c.
Rename __libc_init to _libc_init and call it explicitly from CSU code.
This enforces the constructor run order for newly linked programs.
Keep it as constructor with run-once semantic for binary compatibility.
Implement dl_iterate_phdr for statically linked programs.

best for now because there are too many programs that don't check the return
value of it. Of course cursor motion commands from $TERMCAP have 0 chance
of working now, since their % escapes are not translated to terminfo. In
the window case %+ expects one param from the stack in the termcap case
and two in the terminfo so we barf. We need proper captoinfo handling for
the % escapes, like the one in ncurses. Hi Roy :-)
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.
See http://mail-index.netbsd.org/tech-kern/2011/02/19/msg010025.html
for details.
(to do long double), we need to not only handle the hardware exception
mask and cummulated flags, but also update/query the softfloat variables.
Since this may go away sometime (to make us psABI compliant), ifdef it
properly.
