70d173bfa4 git/fetch: be more robust
currently, git/fetch prints the refs
to update before it fully fetches the
pack files; this can lead to updates
to the refs before we're 100% certain
that the objects are present.

This change prints the updates after
the packfile has been successfully
indexed.

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.

sbrk(0) returns the current end address of the BSS segment,
not the base. This might have been confused with the behaviour
of segbrk(), which when given a zero address returns the base.

2204634275 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.

thanks to Anthony Martin for spotting the bug.

ad37339a1c vmx: reset virtio queue state on device reset
when a virtio device gets reset, we have to also reset the device
shadow indices: availableidx and usedidx. for extra safetly,
we also reset the buffer descriptor table addresses.

this is accomplished by adding a vioqreset(VIOQueue*) function
that brings the queue to its initial reset state.

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.

b68b3a6e19 vt, ssh: don't send interrupts on window resize
When resizing windows, vt would signal ssh by updating

by forwarding both the winch and an interrupt.

This change adds a WINCH generation counter so that
ssh can differentiate between resizes and interrupts.
If an interrupt comes in, and the WINCH generation
changes, then the interrupt is taken as signalling a
WINCH.

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.

775a4bea43 libsec: various changes to tls
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.

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).

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.

unlike other tools like iconv(1), a crop(1) without arguments or with
ones resulting in a no-op, like `-t 0 0', errors out.  other options
like `-i 0' do not error.  this breaks assumptions and results in
tedious intermediary steps or hacks like:

	foo | {crop -t $1 $2 >[2]/null || cat} > baz.bit

instead, just ignore the check.  subsequent code doesn't make

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).

afa5800b5b acme: fix suicide *and* resource leak in ecmd.c (thanks igor)
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:

<snip>
cpu% broke
echo kill>/proc/333310/ctl # acme
cpu% acid 333310
/proc/333310/text:amd64 plan 9 executable
/sys/lib/acid/port

xfidwrite(x=0x461230)+0x28a /sys/src/cmd/acme/xfid.c:479
        w=0x0
        qid=0x5
        fc=0x461390
        t=0x1
        nr=0x100000031
        r=0x45aa10
        eval=0x3100000000
        a=0x405621
        nb=0x500000001
        err=0x419310
        q0=0x100000000
        tq0=0x80
        tq1=0x8000000000
        buf=0x41e8d800000000
xfidctl(arg=0x461230)+0x35 /sys/src/cmd/acme/xfid.c:52
        x=0x461230
launcheramd64(arg=0x461230,f=0x22357e)+0x10 /sys/src/libthread/amd64.c:11
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.

9de5aac7a2 5c, 6c, 7c, 8c, kc, qc, vc: use explicit gmove(... , nn) in cgen() for result of OAS*, OPREINC, OPOSTINC
The expression value of the assignment operation was
returned implicitely by relying on regalloc() on the
right hand side "nod" borrowing the register from nn.

But this only works if nn is a register.

In case of 6c, it can also be a ONAME from a .safe
rathole returned by regsalloc().

This change adds explicit gmove() calls to assign the
expression value. Note that gmove() checks if source
and destination are the same register so it wont emit
redundant move operations in the common case.

The same is applied also to OPREINC and OPOSTINC operations.

b5783b1e39 rio: make window focus changes deterministic, cleanup wind.c
Switching window focus used to be non deterministic
as the current window in focus (Window *input) was set
concurrently while processing window messages such as
Resized and Topped.

This implements a new approach where wcurrent() and
wuncurrent() are responsible for the synchronization
and switch of the input.

It is implemented by sending a Repaint message to the
old input window first, neccesarily waiting until that
window releases the focus and then input is updated
and then a Topped or Reshaped message is send to the
new input window.

Note, that when the whole screen is resized that no
input changes need to happening anymore.

27ad886c95 ip/tftpd: add -n namespace-file flag (thanks sam-d)
tftpd currently unconditionally sets its namespace via /lib/namespace
(newns("none", nil)), which stymied my attempts to pxe boot the
openbsd installer without creating a real /etc dir on 9front, which
would've been gross.

I tried working around this with -h (and -r for good measure), but
again hit issues because the namespace is rebuilt from scratch -- any
binds of /386, /amd64, /cfg/pxe, etc. into the tftp-specific directory
disappeared from tftpd's namespace and rendered my *9front* boxes
unable to boot. I could maintain copies of the needed files in the
tftp-specific directory, but that'd be kind of a drag.

The following patch adds a -n flag to allow the specification of a
namespace file in place of /lib/namespace; similar to ip/ftpd.

I thought about setting up a /lib/namespace.tftp to act as a default
rather than continuing to use /lib/namespace by default (which
security-wise is about the same as allowing 9p mounts by user none,
which I also have disabled), but I had trouble coming up with a sane
default. Maybe someone more experienced would like to try that out.

e77fa31516 libaml: fix IndexField and BankField implementations (thanks Michael Forney)
IndexField is supposed to increment the index value when an
access is done with a bigger size than the data field.
The index value is always a byte offset.

Now that we always calculate the offset for each field unit
access for IndexField, rename the indexv to bank (the bank
value), as it is only used for that. Also, do not compare
it with nil, as it is a integer constant which can be
encoded as nil to mean zero.

For BankField, the banking field was written using store(),
which does nothing when the destination is a Field*.
Use rwfield() to fix it in the new rwfieldunit().

Resolve all the Name*'s when IndexField, BankField and
Field are created. Now, Field.reg points to eigther
Buffer object, Region or Field (data Field of an IndexField).

PS: initial bug report by Michael Forney follows below:

In /dev/kmesg on my T14, I saw a message

	amlmapio: [0xffffff18-0x100000018] overlaps usable memory
	amlmapio: mapping \_SB.FRTP failed

Here is the relevant snippet from my DSDT:

    Scope (_SB)
    {
        ...

        OperationRegion (ECMC, SystemIO, 0x72, 0x02)
        Field (ECMC, AnyAcc, NoLock, Preserve)
        {
            ECMI,   8,
            ECMD,   8
        }

        IndexField (ECMI, ECMD, ByteAcc, NoLock, Preserve)
        {
            Offset (0x08),
            FRTB,   32
        }

        OperationRegion (FRTP, SystemMemory, FRTB, 0x0100)
        Field (FRTP, AnyAcc, NoLock, Preserve)
        {
		...
        }
    }

With some debugging output:

	amlmapio(\_SB.ECMC): Io       72 - 74
	rwreg(\_SB.ECMC): Io       [72+0]/1 <- 8
	rwreg(\_SB.ECMC): Io       [72+1]/1 -> 18
	amlmapio(\_SB.FRTP): Mem      ffffff18 - 100000018
	amlmapio: [0xffffff18-0x100000018) overlaps usable memory
	amlmapio: mapping \_SB.FRTP failed

It seems that libaml does not handle IndexField correctly and just did
a single read from ECMD after setting ECMI to 8, causing the FRTP
region to be evaluated as 0xffffff18-0x100000018. Instead, it should
be reading 4 bytes [18 c0 22 cc], evaluating it as

I wrote a patch (attached) to fix this, and it seems to work. Though,
it's not clear to me when things should be dereferenced. Previously,
the data field was dereferenced at evalfield, but the region and index
field were not until rwfield. After the patch, the index field is
also dereferenced in evalfield.

For BankField, the index *is* dereferenced in evalfield. I'm pretty
sure that this means that BankField does not work currently, since
store() just returns nil for 'f' objects. The bank selector will
never get set.

Anyway, I don't know if this solves any real problems; it's just
something I noticed and thought I'd try to fix.

245264e371 upas/marshal: handle nonexistent save folder correctly (thanks sirjofri)
When the save folder did not exist, and we could not create
it, we would handle up to one Biobuf worth of message, and
then fail, due to a failed tee. The sequence of events leading
up to this was:

	openfolder() -> error
	tee(0, fd, -1) -> wait for read
	write(0, data) ->
		write(fd, data) -> ok
		write(-1, data) -> error, tee terminates
	write(0, attachment) -> error

This change prevents us from writing to a closed fd, and
therefore from erroring out when sending.

We also warn the user.

Subject: Re: [9front] transient dns errors cause smtp failure
Reply-To: 9front@9front.org

I think I found a reason for DNS failing on known good domains.

/sys/src/cmd/ndb/dns.h:156,157
	/* tune; was 60*1000; keep it short */
	Maxreqtm=	8*1000,	/* max. ms to process a request */

So, 8 seconds is how much the resolver will bother with a request it
has been handed, before dropping it on the floor with little
explanation.

It seems quite possible that this is too short a timeout on a machine
during a spam queue run, which predictably stresses the compute and
network resources.

In turn, negative response caching might explain why a particular
unlucky domain would basically stop receiveing any mail for a while.

I'm dying to know if bumping this limit would clear up the queue of
such DNS errors.

29fbba7b6d [9front] upas/vf: exclude mime boundary from temporary attachment files
validateattachment has no business with the mime boundary; it is not
part of the attachment itself.

Also, it causes the boundary to be dropped in the message output from
upas/vf, effectively dropping the following attachment (though the
content is still present after the last boundary of the wrapped first
attachment part).

Consider the following sequence of events:
1. upas/vf is run on a message containing two attachments.
2. The first attachment does not have a known extension, so is saved
   to a temporary file *including* the following mime boundary.
3. This file is opened as p->tmpbuf, which is used for subsequent
   reads until switching back to stdin.
4. The attachment fails validateattachment, so upas/vf wraps it in a
   multipart with a warning message.
5. problemchild() calls passbody(p, 0), which copies from p->tmpbuf
   until it hits the outer boundary line, which it excludes, seeks
   back one line, then returns the outer multipart.
6. problemchild() then writes its own boundary, and then copies one
   line from *stdin* to stdout, expecting the outer boundary.
   However, this boundary was already read from stdin in 2, so it ends
   up reading the first line of the subsequent part instead.

To fix this, pass 0 to passbody() in save() to exclude it from the
attachment file and make it available in stdin when expected.

e502abe001 games/gb: various HDMA fixes
H-blank DMA should only transfer 16 bytes per h-blank, rather than
waiting for the first h-blank and then transferring the whole size.

HDMAC should read 0xff when the transfer is finished, and 0 in the
high bit when the transfer is ongoing. Also, if 0 is written in the
high bit, the current transfer should be aborted.

Introduce two flags, DMAREADY and DMAHBLANK rather than special
constants 1 and -1. If dma is non-zero, there is an ongoing DMA. If
DMAREADY is set, the next chunk is ready to transfer.

Reference: https://gbdev.io/pandocs/#ff55-hdma5-cgb-mode-only-new-dma-length-mode-start

Tested with pokemon crystal.

What was happening is that when the game was loading N background tiles
into vram (each 16 bytes, so one per h-blank), it did something like
this:
- start an hdma transfer for N+1 tiles
- after the Nth tile is transferred, it would read HDMA5, clear the
high bit, then write it back to abort the transfer.

games/gb would instead transfer all N+1 tiles at once, overwriting one
extra tile with whatever was 1 past the end of the source array, and
then would interpret the cancel request as the start of a new transfer
of 16 bytes, which would copy an additional tile past the end. The end
result is that every transfer would end up copying N+2 tiles instead
of just N, overwriting certain tiles with whatever was after the end
of the source data.

keep a nice simple 1:1 mapping (with pci dma addresses

This change adds the RFNOWAIT call to all the processes
we don't need to wait for, so that the places that do
need wait will always get the correct child.

1047b53efc ape/libap: fix _startbuf, check rfork return (thanks pixelherodev)
When _startbuf is invoked, it would crash on the second invocation
if creating a mux segment failed. This is because the first attempt
would assign the return value -1 to the global mux variable, and
the second attempt would notice that the global mux was not nil,
and would attempt to use it.

This change only assigns to the global variable if the allocation
of the segment was a success.

While we're here, we should also check the return of the rfork call.

cb7ba0e640 dd: error with invalid size suffixes, add 'm'
When invoking with dd with an invalid size suffix, we
silently accept the suffix. This can lead to confusion,
because lines like:

	dd -bs 1K
	dd -bs 1m

will silently copy in 1-byte increments. This has caught
people by surprise. While we're at it, megabytes are
convenient, so let's have them too.

8c9cbbb142 passwd: make legacy mode explicit
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.

29f60cace1 kernel: avoid palloc lock during mmurelease()
Previously, mmurelease() was always called with
palloc spinlock held.

This is unneccesary for some mmurelease()
implementations as they wont release pages
to the palloc pool.

This change removes pagechainhead() and
pagechaindone() and replaces them with just
freepages() call, which aquires the palloc
lock internally as needed.

freepages() avoids holding the palloc lock
while walking the linked list of pages,
avoding some lock contention.
