inconsitencies between kernel and filesystem idea of file size during
writes with IO_APPEND.
At mine, this resulted in a configure script producing config.status
with ": clr\n" lines stripped (not 100% reproductible, but always this
specific string. That is of little interest except for my own future
reference).
When a write is in progress, getattr/setattr get/set the maximum size
among kernel idea (grown by write) and filesystem idea (not yet grown).
Push -Wno-array-bounds down to the cases that depend on it.
Selectively disable warnings for 3rd party software or non-trivial
issues to be reviewed later to get clang -Werror to build most of the
tree.
rm dir/file while dir was never looked up since the mount. In that
situation, we get lookup with pcn_nameiop NAMEI_DELETE for dir before
we get it for file. But for dir we are just looking for PUFFS_VEXEC.
This is solved by honouring NAMEI_ISLASTCN, which is set for the last
element only
- do not send O_EXCL to FUSE as documentation forbids it.
- fix warning
perfused stays in foreground. The difference is a mistake and was not
intended.
There is still a bug ready to bite here, since SOCK_STREAM is not reliable.
We just hope that buffers are big enough to hold all packets, but if they
are overflown, we loose a packet and a file operation gets stuck.
We really nee SOCk_SEQPACKET here, but unfortunately it is very broken at
that time.
-clip number of rounds at 31 -- this is log2 of the real number,
and anything larger would break exponentation
-catch possible atoi() error where log2(rounds) is parsed in the
salt prefix
-zero crypto state on exit

inside the environment is not a good idea, we may overwrite it when
fetching other details of the sigjmp environment.
Instead move it to the very end again.
Do not bother to save volatile (caller saved) global registers.
Fixes PR port-sparc64/44918.
jmp_buf, add a compile time assert to catch this kind of divergence
in the C code.
Move the fixed "%npc = %pc + 4" computation to longjmp, this frees
the sigcontext sc_npc value. Use this space to save the savemask
for siglongjmp (we have run out of space behind the globals).
Fixes the tests/lib/libc/setjmp/t_threadjmp tests, and also hopefully
fixes PR port-sparc64/44902.
Verification is now done in the lookup method, as it is the way to
go. Of course there are corner cases, such as the sticky bit which
need special handling in the remove method.
- Set full fsidx in vftstat method
- Do not pass O_APPEND to the filesystem. FUSE always sends the
write offset, so setting O_APPEND is useless. If the filesystem
uses it in an open(2) system call, it will even cause file
corruptions, since offsets given to pwrite(2) will be ignored.
This fix allows glusterfs to host a NetBSD ./build.sh -o build
- Do not use the FUSE access method, use getattr and check for
permission on our own. The problem is that a FUSE filesystem will
typically use the Linux-specific setfsuid() to perform access
control. If that is missing, any chack is likely to occur on
behalf of the user running the filesystem (typically root), causing
access method to return wrong information.
- When possible, avoid performing a getattr method call and use
cached value in puffs_node instead. We still retreive the latest
value by calling getattr when performing append write operation,
to minimize the chances that another writer appended since the
last time we did.
- Update puffs_node cached file size in write method
- Remove unused argument to perfuse_destroy_pn()
requested in PR lib/41931 by Havard Eidnes (the PR refers to POSIX,
the OSF/1 manpage suggests that XOPEN should behave that way too)
being here, do the same to log10 and log2
space is large enough, to handle the edge case where len is
large (up to SSIZE_MAX may be valid on some machines) causing
pointers to wrap around and the fail condition to be missed.
- Update TCB for the initial thread in pthread__initthread, not
pthread__init to get it valid as soon as possible.
- Don't overwrite the pt_tls field in pthread__initthread.
- Don't deallocate pt_tls in pthread__scrubthread. This worked more by
chance than by design.
- Handle freeing the TLS area in pthread_create after removing the
thread instance from the dead queue.
If the argument provided to pidfile(3) contains a '/', then the value is
considered to be an absolute/relative path and the pid file is created
in the given location.
Otherwise, pidfile(3) behaves as before and treats the provided value as
a basename to construct a pid file in /var/run/<basename>.pid. This means
that to create a pid file named "foo.pid" in the current directory, one
must specify "./foo.pid".
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.

_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

(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.
