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.

Added a ver= field to the filter to distinguish the ip version.
By default, a filter is parsed as ipv6, and after parsing
proto, src and dst fields are converted to ipv4. When no
ver= field is specified, a ip version filter is implicitely
added and both protocols are parsed.
This change also gets rid of the fast compare types as the
filed might not be aligned correctly in the packet.
This also fixes the ifc= filter, as we have to check any
local address.
The new command marks the target window as a scratch window -- a window
whose state cannot be "dirtied" by changes made to its body, therefore
avoiding warnings about unsaved changes when deleting the window or
exiting acme.
Existing examples of scratch windows are error, directory, and guide
windows, whose scratchness is set internally.
With the new command users and programs alike can create their own
scratch windows. This is put to use in acme's own win(1).
This makes the flagfmt parser more robust and accepting
a looser input language — namely by allowing whitespace
around specifier fields and ignoring any empty fields.
Long flagfmts can thus be pleasingly displayed:
flagfmt='
a, b, c, C:cache,
m:mtpt mountpoint,
s:srvn srvname'
Fix inconsistencies between programs and their usage
messages, correct instances where information seems
to be missing or lost. This includes missing arguments,
making usage consistent with manuals, and so on.
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.
with the -s flag, we should read 9P messages from
standard *INPUT* (fd 0) and write responses to
standard *OUTPUT* (fd 1).
before these servers where reading from fd 1,
assuming they where both the same files.
it is unclear how Srv.nopipe flag should work inside
postmountserv(). if a server wants to serve on stdio
descriptors, he can just call srv() after initializing
Srv.infd and Srv.outfd.
The Srv.leavefdsopen hack can be removed now that acme
win has been fixed.
the console command runs a command or the system shell under
a new instance of kbdfs, optionally providing a serial console
when $console environment variable is set.
this is a reimplementation of infernos os(1) command, which
allows running commands in the underhying host operating
system when inferno runs in hosted mode (emu). but unlike
inferno, we want to use it to run commands on the client
side of a inferno or drawterm session from the plan9 cpu
server, so it defaults to /mnt/term/cmd for the mountpoint.

I needed to convert the RSA private key that was laying around in
secstore into a format understood by UNIX® tools like SSH.
With asn12rsa(8) we can go from the ASN.1/DER to Plan 9 format, but not
back - so I wrote the libsec function asn1encodeRSApriv(2) and used it in
rsa2asn1(8) by adding the -a flag which causes the full private key to be
encoded and output.
C99 comments have been the default in compilers for something like 20 years
now. This means we don't need to remember to turn it on when porting software,
and gets rid of cryptic errors about unterminated character constants when
someone writes something like:
// Didn't need to...
We still accept the flag to avoid breaking mkfiles, but we do nothing with it.
This also removes the documentation, since the option does nothing now.
we want to accept V4 subnets in CIDR notation consistently which
means we need to interpret the mask in context of the IP address.
so parseipmask() now has an additional v4 flag argument which
offsets the prefixlength by 96 so a /24 will be interpreted
as a /120.
parseipandmask() is the new function which handles this automatically
depending on the ip address type.
v4parsecidr() is now obsolete.
"I sometimes find myself on either slow or data-capped network links where downloading images isn't ideal. Attached is a simple patch to mothra that changes the 'k' command to not only remove already-downloaded images from a page, but also toggle a state such that mothra won't attempt to download images on future visited sites until 'k' is toggled again. This also adds a '-k' flag to mothra which enables the flag at startup." --Jeremy O'Brien<neutral@fastmail.com> on 9fans
- fix overwriting channel 10 with channel 9
- fix using channel volume instead of last volume when setting note
(fixes d_doom and others)
- remove useless state
this driver makes regions of physical memory accessible as a disk.
to use it, ramdiskinit() has to be called before confinit(), so
that conf.mem[] banks can be reserved. currently, only pc and pc64
kernel use it, but otherwise the implementation is portable.
ramdisks are not zeroed when allocated, so that the contents are
preserved across warm reboots.
to not waste memory, physical segments do not allocate Page structures
or populate the segment pte's anymore. theres also a new SG_CHACHED
attribute.
the string encoding functions touch secret key material
in a bunch of places (devtls, devcap), so make sure we do
not leak information by cache timing side channels, making
the encoding and decoding routines constant time.
we also expose the alphabets through encXchr()/decXchr()
functions so caller can find the end of a encoded string
before calling decode function (for libmp).
the base32 encoding was broken in several ways. inputs
lengths of len%5 == [2,3,4] had output truncated and
it was using non-standard alphabet. documenting the alphabet
change in the manpage.
Instead of only using a hash over the whole certificate for
white/black-listing, now we can also use a hash over the
Subject Public Key Info (SPKI) field of the certificate which
contians the public key algorithm and the public key itself.
This allows certificates to be renewed independendtly of the
public key.
X509dump() now prints the public key thumbprint in addition
to the certificate thumbprint.
tlsclient will print the certificate when run with -D flag.
okCertificate() will print the public key thumbprint in its
error string when no match has been found.
yes, it peeks into IP packets to handle fragmentation when sending
onto tunnel ports and does mss clamping. but it can carry arbitrary
ethernet packets just fine (between ethernets).
instead of hardcoding the tunnel interface MTU to 1280,
we calculate the tunnel MTU from the outside MTU, which
can now be specified with the -m mtu option. The deault
outside MTU is 1500 - 8 (PPPoE).
Add assembler versions for aes_encrypt/aes_decrypt and the key
setup using AES-NI instruction set. This makes aes_encrypt and
aes_decrypt into function pointers which get initialized by
the first call to setupAESstate().
Note that the expanded round key words are *NOT* stored in big
endian order as with the portable implementation. For that reason
the AESstate.ekey and AESstate.dkey fields have been changed to
void* forcing an error when someone is accessing the roundkey
words. One offender was aesXCBmac, which doesnt appear to be
used and the code looks horrible so it has been deleted.
The AES-NI implementation is for amd64 only as it requires the
kernel to save/restore the FPU state across syscalls and
pagefaults.
there isnt much of a point in keep maintaining separate
kernel configurations for terminal and cpu kernels as
the role can be switched with service=cpu boot parameter.
to make stuff cosistent, we will just have one "pc" kernel
and one "pc64" kernel configuration now.
raiz → the reason that the manpage example works not because
it's a correct timezone file format, but because readtimezone()
(in libc) fails and defaults to GMT.
initThumbprints() now takes an application tag argument
so x509 and ssh can coexist.
the thumbprint entries can now hold both sha1 and sha256
hashes. okThumbprint() now takes a len argument for the
hash length used.
the new function okCertificate() hashes the certificate
with both and checks for any matches.
on failure, okCertificate() returns 0 and sets error string.
we also check for include loops now in thumbfiles, limiting
the number of includes to 8.
Once the Barnes-Hut tree is constructed, the gravitational
force calculations can be done in parallel by dividing the
bodies up between a number of procs.
