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.

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()

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

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.

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.

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.

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.

Thanks to Ori for input and a preliminary patch.

d9564c0642 git: separate author and committer
Git has the ability to track the person who
creates a commit separately from the person
who wrote the commit. For git9, we ignored
this feature.

However, as we start using git/import more,
it will be useful to figure out who imported
a commit, as well as who wrote it.

This change adds support for seeing this
information in git, as well as setting the
author and committer separately in git/import.

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]

However, clean and nuke also remove build files for 0 (spim) and q

build all the kernels, even those which are not supported.  For
example, I tried to build the power arch (qc, qa, ql) and without
surprise it failed (when building dtracy): ...

The patch below skips over non-supported architectures.  Is that

97c6a1dd52 snoopy: fix dns nil pointer crashes when formating dns packets (thanks sl)
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.

We used to use performance cycle counter for cycles(),

the cores are idle.

Most callers expect cycles() to return a high resolution

and enable the userspace generic timer virtual counter.

git/fetch: ensure we clean packfiles on failure

When pulling into a git repository that is group
writable as a non-owner, the pack file is left
in place because we do not have permission to
remove it.

We also leave it behind if we bail out early due
to an error, or due to only listing the changes.

This pushes down the creation of the file, and
cleans it up on error.

Also, while we're here, clean up index caching,
and ensure we close the fd in all cases.

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.

88060e7501 libsec: add X509reqtoRSApub() function and return subject alt names in X509to*pub() name buffer
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.

apparently, we need to provide the context specific tag

have subjectAltNames).

for this, we change mkcont() to take a Elist* instead,
which then can be nil when not used. also put the tag

57d95c7325 libsec: move zero check to curve25519_dh_finish()
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.

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.

c2297ce5c1 kernel: use 64-bit virtual entry point for expanded header, document behaviour in a.out(6)
For 64-bit architectures, the a.out header has the HDR_MAGIC flag set
in the magic and is expanded by 8 bytes containing the 64-bit virtual
address of the programs entry point. While Exec.entry contains physical
address for kernel images.

Our sysexec() would always use Exec.entry, even for 64-bit a.out binaries,
which worked because PADDR(entry) == entry for userspace pointers.

This change fixes it, having the kernel use the 64-bit entry point
and document the behaviour in the manpage.

682414ce0d vmx: fix 9p debug server and make it compatible to /proc
The 9p debug server was broken as it assumed the first
tree file added would have a qid of 0 (it has a qid
of 1 as the root directory is using 0 already).

Instead, just compare File* pointers and get rid of
the table (less code).

When passing 64-bit unsigned addresses as 64-bit signed
file offsets, we have to make sure to not pass negative
offsets (filtered out by kernel and lib9p)!
This is solved by clearing and sign bit in encoding and
63-bit sign extension on decoding.

Make the mem file writable (needed for acid).

The 9p debug server provided a single directory containing
mem and regs files. This patch renames the regs file
(which is in vmx specific text format) to "xregs" and
adds "regs" and "kregs" file which use the same format
as exported by the kernels /proc filesystem.

This allows one to bind the vmx directory over a proc
directory and attach acid to a running system like:

mount -b /srv/vmx /proc/1
acid -k -lkernel 1 /sys/src/9/pc64/9pc64

7048f1ca11 games/opl3: use correct sampling rate
games/dmid uses the same sample rate as the chip for music, but other
applications do not.  opl3 and its older version opl2 (not in 9front)
read an input stream of commands in basically IMF format, something
used in other id Software games and some others, which assumes a
given input sampling rate:  700 Hz for Wolfenstein 3D music, 560 Hz
for Commander Keen, 60 Hz for Ultima 6, etc.

The opl3 emulation on the other hand is not really intended to run at
a sampling rate different that the chip's 49.716 kHz sampling rate.
Previously, we assumed it runs at 44.1 kHz and just used the input
rate as a divisor to get the number of samples per delay tic.

From what I understand, the correct way to use it for accurate
emulation is to run the opl chip emulator at its intended sampling
frequency, then downsample to 44.1 kHz.  This means better output
but more code.  The alternative is to basically do the same as
before rev 8433, except with no buffering, but at accuracy/quality
loss.  This change implements the former and just forks pcmconv to
deal with resampling.

f6509078ed lib9p: expose Srv.forker handler and srvforker(), threadsrvforker() and threadsrv() functions
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.

e0cf0261d0 resample: improve performance (thanks José Miguel Sánchez García)
Resample is well known for taking a long time to resize an image. This
patch brings an important performance boost (in my test image, time
was reduced from ~2850ms to ~500ms). It does that by extracting FP
multiplication and division out of the innermost loop of
resamplex/resampley.

The results differ slightly from the current implementation: in my
test: ~0.3% of the bytes had a ±2 difference in their value, which I
attribute to rounding errors. I'm personally not concerned with that
deviation, given the performance gains. However, I recommend testing
it just to be sure I didn't overlook anything.

295acd7e0d kernel: get rid of physical page bank array and use conf.mem[] instead
We can take advantage of the fact that xinit() allocates
kernel memory from conf.mem[] banks always at the beginning
of a bank, so the separate palloc.mem[] array can be eleminated
as we can calculate the amount of non-kernel memory like:

upages = cm->npage - (PGROUND(cm->klimit - cm->kbase)/BY2PG)

for the number of reserved kernel pages,
we provide the new function: ulong nkpages(Confmem*)

This eleminates the error case of running out of slots in
the array and avoids wasting memory in ports that have simple
memory configurations (compared to pc/pc64).

To reproduce the suicide try running the following in acme:

• 'Edit B <ls lib'

by select and middle clicking in a window that is in your $home.

There is a very high chance acme will commit suicide like this:

0xfefefefefefefefe ?file?:0
</snap>

The suicide issue is caused by the following chain of events:

• /sys/src/cmd/acme/ecmd.c:/^edittext is called at
/sys/src/cmd/acme/xfid.c:479 passing nil as its first parameter:

<snip>
...
        case QWeditout:
                r = fullrunewrite(x, &nr);
                if(w)
                        err = edittext(w, w->wrselrange.q1, r, nr);
                else
                        err = edittext(nil, 0, r, nr);
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
...
</snap>

...and /sys/src/cmd/acme/ecmd.c:/^edittext dereferences the
first parameter that is *nil* at the first statement:

<snip>
char*
edittext(Window *w, int q, Rune *r, int nr)
{
        File *f;

        f = w->body.file;
^^^^^^^^^^^^^^^^^^^^^
This will crash if 'w' is *nil*

        switch(editing){
...
</snap>

Moving the the derefernce of 'w' into the case where it is
needed (see above patch) fixes the suicude.

The memory leak is fixed in /sys/src/cmd/acme/ecmd.c:/^filelist.  The
current implementation of filelist(...) breaks its contract with its
caller, thereby leading to a memory leak in /sys/src/cmd/acme/ecmd.c:/^B_cmd
and /sys/src/cmd/acme/ecmd.c:/^D_cmd.

The contract /sys/src/cmd/acme/ecmd.c:/^filelist seems to have with
its callers is that in case of success it fills up a 'collection' that
callers can then clear with a call to clearcollection(...).

The fix above honours this contract and thereby removes the leak.

After you apply the patch the following two tests should succeed:

• Execute by select and middle click in a Tag:
        'Edit B lib/profile'

• Execute by select and middle click in a Tag:
        'Edit B <ls lib'

The former lead to a resource leak that is now fixed.

The latter lead to a suicide that is now fixed by moving the statement
that dereferences the parameter to the location where it is needed,
which is not the path used in the case of 'Edit B <ls'.

Cheers,
Igor

a2ebe5c79a devfs: fix locking and ignore undocumented "fsdev:\n" configuration signature
The confstr was shared between readers so seprintconf() could
write concurrently to that buffer which is not safe.

This replaces the shared static confstr[Maxconf] buffer with a
pointer that is initially nil and a buffer that is alloced on
demand.

The new confstr pointer (and buffer) is now only updated while
wlock()ed from the new setconfstr() function.

This is now done by mconfig() / mdelctl() just before releasing
the wlock.

Now, rdconf() will check if confstr has been initialized, and
test for it again while wlock()ed; making sure the configuration
is read only once.

Also, rdconf() used to check for a undocumented "fsdev:\n" string
at the beginning of config data tho that was never documented.

This changes mconfig() to ignore that particular signature so
the example from the manpage will work as documented.

4a83ce37c6 libsunrpc: work around arm64 compiler bug in sunStringUnpack()
The sunStringUnpack() routine was miscompiled by 7c, as
pointer arithmetic is done in 64 bit but the constant -1
offset got expended to a unsigned 32 bit integer.
