c37de33463 ndb/dns: use decimal encoding for txt rr string escapes
rfc883 suggests to use decimal digits to escape txt rr strings,
and unix dig appears to use the same.
so change from octal to decimal.

5de1f3d9cf ndb/dns: handle txt rr strings as binary, remove nullrr ndb code
txt and caa rr strings might contain binary control characters
such as newlines and double quotes which mess up the output
in ndb(6) format.
so handle them as binary blobs internally and escape special
characters as \DDD where D is a octal digit when printing.

txtrr() will unescape them when reading into internal
binary representation.

remove the undocumented nullrr ndb attribute parsing code.

9d15403fda libc: fix overflow of domain component rune buffer for idn2utf()
If the source string has a run of more than 256 runes without
a "." dot, we'd overflow the runebuffer in idn2utf().

The utf2idn() routine had a check in the while loop, but that
is actually wrong too, as it would insert a dot and restart
the loop in the middle of a domain component. Just error
out if a domain component is too long.

db971a6189 kernel: fix stat bugs
In a few places, we where using a fixed buffer of sizeof(Dir)+100
size for stat. This is not correct and fails if the name returned
in stat is long.

This results in being unable to seek to the end of file with a
long filename.

The kernel should do the same thing as dirfstat() from libc;
handling the conversion and buffer allocation and returning a
freeable Dir* pointer.

For this, a new dirchanstat() function was added.

The fstat syscall was not rewriting the name to the last path
element; fix it.

In addition, gracefully handle the mountfix case, reallocating
the buffer to accomidate the required stat length plus
size of the new name so dirsetname() does not fail.

e0d2453f56 libsec: fix bugs in tls extension handling (thanks kemal)
this patch fixes bugs in tls extension handling:

1. if conn->serverName is an empty string, tlsClientExtensions
will generate a SNI with an empty hostname, which is forbidden
according to RFC 6066:

opaque HostName<1..2^16-1>;

check if conn->serverName has at least one char.

2. checkClientExtensions fail with clients that doesn't have
extensions, because it doesn't check if ext is nil. fix that
up.

3. rewrite checkClientExtensions. some parts of the code does
not check the length properly, and it could be simplified
heavily.

5a807265a8 libthread: fix debug prints, simplify
Do the debuglevel check before calling the print
function for _threaddebug, by making it a macro.
Do not waste cycles passing arguments.

Generalize the _threaddebug function into _threadprint()

also be used from _threadassert().

Fix missing arguments in one case, fix trailing
newlines in _threaddebug().

Make _threadgetproc()/_threadsetproc() a macro,
just dereferencing Proc**_threadprocp.

Simplify the mainjump, just call _threadsetproc()
directly without that mainp dance. Remove the
_schedinit() argument, it uses _threadgetproc() now.

03d870e028 kernel: return error from sysrfork instead of waiting and retrying
The old strategy of wait and retry doesnt seem to
work very well as it keeps all the forking parents
stuck waiting in the kernel worsening the situation.

The idea with this change is to have rfork() return
error quickly; and without whining; as most callers
would just react with a sysfatal() which might be
better for surviving this.

b51d7ca3ba devip: improve tcp error handling for ipoput
The ipoput4() and ipoput6() functions can raise an error(),
which means before calling sndrst() or limbo() (from tcpiput()),
we have to get rid of our blist by calling freeblist(bp).

Makse sure to set the Block pointer to nil after freeing in
ipiput() to avoid accidents.

Fix wrong panic string in sndsynack, and make any sending
functions like sndrst(), sndsynack() and tcpsendka()
return the value of ipoput*(), so we can distinguish
"no route" error.

Add a Enoroute[] string constant.

Both htontcp4() and htontcp6() can never return nil,
as they will allocate new or resize the existing block.
Remove the misleading error handling code that assumes
that it can fail.

Unlock proto on error in limborexmit() which can
be raised from sndsynack() -> ipoput*() -> error().

Make sndsynack() pass a Routehint pointer to ipoput*()
as it already did the route lookup, so we dont have todo
it twice.

Instead of having to do an arp hash table lookup for each
outgoing ip packet, forward the Routehint pointer to the
medium's bwrite() function and let it cache the arp entry
pointer.

This avoids route and arp hash table lookups for tcp, il
and connection oriented udp.

It also allows us to avoid multiple route and arp table
lookups for the retransmits once an arp/neighbour solicitation
response arrives.

55c3138c64 kernel: ensure that all accesses to Mhead.mount is done with Mhead.lock acquired
The Mhead structures have two sources of references to them:

- from Pgrp.mnthash hash-table
- from a channels Chan.umh pointer as returned by namec() for a union directory

Unless one holds the Mhead.lock RWLock, the Mhead.mount chain
can be mutated by eigther cmount(), cunmount() or closepgrp().

Readers, skipping acquiering the lock where:

mountfix(): responsible for rewriting directory entries for
union directory reads; was walking the Mhead.mount chain to
detect if the passed channel itself appears in the mount list.

cmount(): had a check and copy when "new" chan was a union itself
and if the MCREATE flag is set and would copy the mount table.
All this needs to be done with Mhead read-locked while copying
the mount entries.

devproc(): in the handler for reading /proc/n/ns file.

namec(): while checking if the Chan->umh should be initialized.

In addition to this, cmount() is changed to do the mountfree()
of the original mount chain when MREPL is done after releasing
the locks.

Also, some cosmetic changes...

d43d79bda4 devip: implement ipv4 arp timeout with icmp host unreachable notification
The IPv4 ARP cache used to indefinitely buffer packets in the Arpent hold list.
This is bad in case of a router, because it opens a 1 second
(retransmit time) window to leak all the to be forwarded packets.

This change makes the ipv4 arp code path similar to the IPv6 neighbour
solicitation path, using the retransmit process to time out old entries
(after 3 arp retransmits => 3 seconds).

A new function arpcontinue() has been added that unifies the point when
we schedule the (ipv6 sol retransmit) / (ipv4 arp timeout) and reduce
the hold queue to the last packet and unlock the cache.

As a bonus, we also now send a icmp host unreachable notification
for the dropped packets.

move the checkstate() call inside tlsrecwrite() to reuse the

c7dcc82b0b git/query: fix spurious merge requests
Due to the way LCA is defined, a using a strict LCA
on a graph like this:

 <--a--b--c--d--e--f--g
     \               /
       +-----h-------

can lead to spurious requests to merge. This happens
because 'lca(b, g)' would return 'a', since it can be
reached in one step from 'b', and 2 steps from 'g', while
reaching 'b' from 'a' would be a longer path.

As a result, we need to implement an lca variant that
returns the starting node if one is reachable from the
other, even if it's already found the technically correct
least common ancestor.

This replaces our LCA algorithm with one based on the
painting we do while finding a twixt, making it give
the resutls we want.

e279699344 plumber: remove $plumbsrv, add optional srvname, usage check
Plumber both posts a service to /srv and sets a $plumbsrv environment
variable.  Our libplumb no longer uses $plumbsrv and nothing else
does.  It's a silly hack;  rc doesn't update /env immediately, and
scripts, which for instance set up subrios, cannot rely on it to
clean up the plumber at the end.

Instead, add the option to specify a srvname, actually check for some
common errors and print a usage string.

Git has the ability to track the person who

However, as we start using git/import more,

information in git, as well as setting the

1a444750d6 ssh: use RSA/SHA-256 instead of RSA/SHA-1 as the public key algorithm
openssh now disables RSA/SHA-1 by default, so using RSA/SHA-1 will
eventually cause us problems:

https://undeadly.org/cgi?action=article;sid=20210830113413

in addition, github will disable RSA/SHA-1 for recently added RSA keys:

https://github.blog/2021-09-01-improving-git-protocol-security-github/

this patch modifies ssh.c to use RSA/SHA-256 (aka rsa-sha2-256)
instead of RSA/SHA-1 (aka ssh-rsa) as the public key algorithm.

NOTE: public rsa keys and thumbprints are ***NOT AFFECTED***
by this patch.

while we're here, remove the workaround for github.com. it seems
that github has fixed their implementation, and does not look into
macalgs when we're using an aead cipher.

abe0534492 git/{diff,import}: make it easier to handle manually-asembled patch emails
Often, people (including myself) will write emails that
can almost be applied with git/import.  This changes
git/diff and git/import so that things will generally
work even when assembling diffs by hand:

1.	git/import becomes slightly more lax:

		^diff ...
		^--- ...

	will both be detected as the start of a patch.

2.  git/diff produces the same format of diff
	as git/export, starting with paths:

		--- a/path/to/file
		+++	b/path/to/file

	which means that the 'ape/patch -p1' used
	within git/import will just work.

So with this, if you send an email to the mailing list,
write up a committable description, and append the
output of git/diff to the end of the email, git/import
should just work.

[this patch was send through the mailing list using the
above procedure, and will be committed with git/import
to verify that it works as advertised]

snoopy shares ndb/dns's dns parser code, but has its own
copy of rralloc() function, which is responsible to allocating
auxiolary data structures on an RR depending on the type.

ndb/dns gained some support for some new types, but snoopy's
copy of rralloc() was not updated, resulting the auxiolary
structures to be nil, and the shared parsing routines crashes
when trying to dereference them.

this just syncs the copies, we might consider moving rralloc()
into its own file so it can be completely shared.

cfebf83947 git: better handling of absolute paths, regex metachars
Git currently gets a bit confused if you try to
manipulate files by absolute path.  There were also a
number of places where user-controlled file paths ended
up getting passed to regex interpretation, which could
confuse things.

This change mainly does 2 things:

	- Adds a 'drop' function which drops
	  a non-regex prefix from a string, and uses
	  that to manipulate paths, simplifies 'subst',
	  and removes 'subst -g', which was only used
	  with fixed regexes; sed does this job fine.
	- When getting a path from a user, we
	  make it absolute and then strip out the head

Along the way it cleans up a couple of stupids:

	- 'for(f in $list) if(! ~ $#f 0) use $f:
	  $f can't be a nil list because of
	  list flattening.
	- removes a useless substitution here:

	 	all=`$nl{{git/query -c $1 $2; git/query -c $2 $3} | sed 's/^..//' | \
			gsubst '^('$ourbr'|'$basebr'|'$theirbr')/*' | sort | uniq}

	  where git/query -c doesn't produce
	  paths prefixed with the query.

c38fcb5dc3 arm64: use generic timer virtual counter for cycles()
We used to use performance cycle counter for cycles(),
but it is kind of useless in userspace as each core
has its own counter and hence not comparable between
cores. Also, the cycle counter stops counting when
the cores are idle.

Most callers expect cycles() to return a high resolution
timestamp instead, so do the best we can do here
and enable the userspace generic timer virtual counter.

f58d99aa7a virtio: add non-legacy virtio 1.0 drivers for disk and ethernet
The new interface uses pci capability structures to locate the
registers in a rather fine granular way making it more complicated
as they can be located anywhere in any pci bar at any offset.

As far as i can see, qemu (6.0.50) never uses i/o bars in
non-legacy mode, so only mmio is implemented for now.

The previous virtio drivers implemented the legacy interface only
which uses i/o ports for all register accesses. This is still
the preferred method (and also qemu default) as it is easier to
emulate and most likely faster.

However, some vps providers like vultr force the legacy interface
to disabled with qemu -device option "disable-legacy=on" resulting
on a system without a disk and ethernet.

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.

As checking for all zero has to be done in a timing-safe
way to avoid a side channel, it is best todo this here
instead of letting the caller deal with it.

This adds a return type of int to curve25519_dh_finish()
where returning 0 means we got a all zero shared key.

RFC7748 states:

The check for the all-zero value results from the fact
that the X25519 function produces that value if it
operates on an input corresponding to a point with small
order, where the order divides the cofactor of the curve.

1. add the curve x25519 to tls, both client and server.
it's more faster, immune to timing attacks by design,
does not require verifying if the public key is valid,
etc etc. server-side has to check if the client supports
the curve, so a new function has been introduced to parse
the client's extensions.

2. reject weak dhe primes that can be easily cracked with
the number field sieve algorithm. this avoids attacks like
logjam.

3. stop putting unix time to the first 4 bytes of client/
server random. it can allow fingerprinting, tls 1.3 doesn't
recommend it any more and there was a draft to deprecate
this behaviour earlier.[1]

4. simply prf code, remove useless cipher enums.

Note how the days (i.e. ' M Tu  W Th  F Sa Su') for Feb and Mar
do not align with the day numbers.

This is because an extra space is left *before* adding the terminating
'\0' via the pointer `dayw`.

With the patch applied the calendar aligns nicely for the year view:

  term% cal -s1 2021
                                  2021

1da1ac52d2 git/branch: resolve implicit branch switch before using it
When switching a branch implicitly -- ie, creating a local
branch off of a remote branch -- we would get the list of
changed files before we would resolve the implicit branch
switch, leading to an empty list of changes.

1210b12f28 troff: fix mangled fonts and character files
All of these files appear to have been imported from sources in a
case-insensitive manner and consequently lost their original content.

- Hx, Hb, and Hi fonts should be narrow versions of Helvetica

- c[1-3] fonts should be condensed versions of Century Old Style

- the lH character should be a filled left hand symbol

- the rh character should be a stroked right hand symbol

- the rc character should be the right ceiling symbol

I've verified that these are the only files that collide with others
when ignoring case (aside from rc/bin/[Kk]ill but those are correct).

7c3ff53574 git/import: handle mails with line wrapping and mime
git/import expected a patch, however upas/fs serves
either a raw file without any of the mime decoding
and line joining, or a directory, with the headers
and body split out.

This makes it a pain to apply some mails.

So, here we teach git to import upas dirs natively,
making it easy to handle all patches that come in
as emails.
