We need a way to parse a rsa certificate request and return the public
key and subject names. The new function X509reqtoRSApub() works the
same way as X509toRSApub() but on a certificate request.
We also need to support certificates that are valid for multiple domain
names (as tlshand does not support certificate selection). For this
reason, a comma separated list is returned as the certificate subject,
making it symmetric to X509rsareq() handling.
A little helper is provided with this change (auth/x5092pub) that takes
a certificate (or a certificate request when -r flag is provided) and
outputs the RSA public key in plan 9 format appended with the subject
attribute.
There are a number of alphabets in common use for base32
and base64 encoding, such as url-safe encodings.
This adds support for passing a function to encode into
arbitary alphabets.
Now that we have these new functions,
we can also make them return an error
instead of calling sysfatal() like
postmountsrv().
Remove the confusing Srv.srvfd, as it
is only temporarily used and return
it from postsrv() instead.
To use srvrease()/srvaquire() we need to have a way to spawn
new processes to handle the service loop. This functionality
was provided by the internal _forker() function which was
eigther rfork or libthread based implementation depending on
if postmountsrv() or threadpostmountsrv() where called.
For servers who want to use srv() directly, _forker would not
be initialized so srvrelease() could not be used.
To untangle this, we get rid of the global _forker handler
and put the handler in the Srv structure. Which will get
initialized (when nil) to eigther srvforker() or threadsrvforker()
depending on if the thread or non-thread entry points where used.
For symmetry, we provde new threadsrv() and threadpostsrv()
functions which handle the default initialization of Srv.forker.
This also allows a user to provide his own forker function,
maybe to conserve stack space.
To avoid dead code, we put each of these function in their
own object file. Note, this also allows a user to define its
own srvforker() symbol.
* Add the %ll length modifier,
* Convert nil to "<nil>" under %s (not in APE),
* Cast void* to uintptr under %p,
* Use "0x" hex prefix under %p,
* Fix manual page mentions of %P to %p,
* Fix empty result for fp conversions,
* Fix zero padding of left-aligned fp conversions,
* Remove deprecated #pragma ref uses.
Most of these were introduced in APE prior to 9front.
I've omitted the %z conversion specifier since Plan 9 code
rarely uses the usize type. This may need to be added later
for the benefit of native ports of alien code.
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 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.
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.
Ignoring '?' when formatting date strings allows
the format strings to be reused for parsing. This
is convenient, since we don't need to duplicate
the format strings.
There were a number of ideas that were tried out as the tmdate
api evolved. As a result, there were some references in the
manpage to things that are no more.
Fix them.
Ctime is defined as printing a 3-character timezone
name. The timezone name is ambiguous. For example,
EST refers to both Australian and American eastern
time. On top of that, we don't want to make the
tzabbrev table exhaustive. So, we put in this hack:
Before we consult the well known table of timezones,
we check if the local time matches the timezone name.
On top of that, tm2sec
If you want unambiguous timezone parsing, use numeric
timezone offsets (Z, ZZ formats).
We almost always want to skip leading whitespace in time
formats, so make tmparse just do it. This fixes upas mbox
parsing, which leaves a leading whitespace at the start of
the date.
The current date and time APIs on Plan 9 are not good. They're
inflexible, non-threadsafe, and don't expose timezone information.
This commit adds new time APIs that allow parsing arbitrary
dates, work from multiple threads, and can handle timezones
effectively.
this breaks the sample from the seconds manpage, and overall
produces funky results. this needs alot more testing.
term% seconds '23 may 2011'
seconds: tmparse: invalid date 23 may 2011 near 'may 2011'
term% seconds '2019-01-01 00:00:00'

Redo date handling in libc almost entirely. This allows
handling dates and times from outside your timezones,
fixes timezone loading in multithreaded applications,
and allows parsing and formatting using custom format
strings.
As a test of the APIs, we replace the formatting code in
seconds(1), shrinking it massively.
The last commit missed a few removals, and made it
unnecessarily hard to do an update.

with the latest changes to shr(3), we can use ORCLOSE on
the control file to get the mount in the share automatically
removed when the server exits or something goes wrong during
postsharesrv().
do not expose postfd() and sharefd() functions. they where
undocumented and leak the control file descriptors.
