Passwd used to produce a very confusing error
about DES not being enabled whenever the password
was mistyped. This happened because we attempted
to guess what authentication method to use, and
preseneted the error from the wrong one on failure.
This puts the legacy mode behind a flag, so that
we don't even try the old method unless it's
explicitly requested.

add missing tmdate() call around %τ format.

This patch exposes the bezierpts function,
providing a way to get the points on a path,
similar how bezsplinepts gives them for b
splines.

The Qid struct is pervasive when writing 9p servers,
but is not described in the manpages. This adds a
definition to the 9pfid manpage.

Tilting allows using left/right rotated or invetrted display orientation.
This can be changed at runtime such as: echo tilt right > /dev/vgactl
This removes the old panning and vga overlays as they are only implemented
with some ancient vga controllers.

The idea is to avoid the magic files that contain
per process information in devcons when possible.
It will make it easier to deprecate them in the future.

Provide a central function to change the user id
of the calling process.
This is mostly used by programs to become the none
user, followed by a call to newns().
|
|
The devcons driver is really the wrong place to
serve per process information.
|
|
The process group id is essentially a unique id
of the namespace but it was never well documented
nor is it used by any program.

hget supports adding custom headers with -r;
it makes sense for hpost to do the same, both
because custom headers are more likely necessary
with POSTs, and for consistency.

The initial protocol handling in exportfs for
cpu and import services is a huge mess.
Saparate the code out into its own program with
its own oexportfs(4) manpage.

opening /fd, /srv and /shr
The OCEXEC flag used to be maintained per channel,
making it shared between all the file desciptors.
This has a unexpected side effects with regard to
channel passing drivers such as devdup (/fd),
devsrv (/srv) and devshr (/shr).
For example, opening a /srv file with OCEXEC
makes it impossible to be remounted by exportfs
as it internally does a exec() to mount and
re-export it. There is no way to reset the flag.
This change makes the OCEXEC flag per file descriptor,
so a open with the OCEXEC flag only affects the fd
group of the calling process, and not the channel
itself.
On rfork(RFFDG), the per file descriptor flags get
copied.
On dup(), the per file descriptor flags are reset.
The second modification is that /fd, /srv and /shr
should reject the ORCLOSE flag, as the files that
are returned have already been opend.

The -v flag now does not create a new rio window,
while -w flag does (restores the old behaviour).
This allows vmx to run under vncs and is in general
mode aligned to other emulators and programs.

Initially the code tried to guess the date format. This
turned out to be a bit too magical, so the feature was
removed, but the manpage still documented the nonfeature.

the efi loader now looks for plan9.ini and the kernel in the ESP
first, before looking elsewhere.

The pop3 options were prefixed with a '-'; the
imap4d options were not. Proofreading, foolks.

Upas/marshal -F was broken with the '-8' command, and silly
without it: It used aliases passed on the command line, so
the destination address was ignored with -8 was passed.
In addition, it would create a new mailbox for any aliases
being sent to, instead of putting them all in one location.
The new -S option is similar to -F, but specifies where the
message should go.

This allows us to attach additional context
to the biobuf so can read from some sort of
data structure without a global variable.

The documentation for mp(2) claimed we'd return nil on error, when
we actually sysfatal. This corrects the documentation to match our
actual behavior.
