5e040b3a2b libthread: generate correct acid files
/sys/src/cmd/mksyslib uses `{basename $stem .$objtype}^.c to get the
source file name for *.acid files.  /sys/lib/acid/thread expects
sched.$objtype.acid.  This lets /sys/src/libthread/mkfile generate
that file.

4c981d440d [9front] walk: properly format permissions
This patch adds dirmodefmt from fcall.h to pretty-print file
permissions, similarly to ls -l. I didn't notice any performance
degradation.

I hope no-one relied on the old behaviour.

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
/sys/lib/acid/amd64
acid: lstk()
edittext(nr=0x31,q=0x0,r=0x45aa10)+0x8 /sys/src/cmd/acme/ecmd.c:135
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.

9162533526 Mail: separate deletion from relinking messages
Mutating lists that are being iterated is needlessly error

Separating deletion into a redraw/relink and zap phase

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.

85e4383835 [9front] riostart: make text window focused by default
This change makes the text window be focused on startup when using
default riostart (e.g: when using the release ISO). This little change
makes you able to immediately reach the rc shell without clicking the
window, which at the very least is more convenient, and if you have
problems to use your mouse but want to install the system, you also
can (I had to stop profile from running at boot to patch it in my VPS
KVM console because the mouse wasn't working properly. Could install
and setup it to connect through drawterm).

do not free the pcidev on card removal, as the drivers

instead, we provide a pcidevfree() function that just unlinks

(May be due removing overheads in 16->24 conversions?)

But on rpi4 r and b channels are swapped.  So, i changed BGR24 to

692919521c vmx: reduce cpu load by eliminating nop-loop
Sacrifice some of the sub-millisecond timer precision in favor of less
cpu load when the timer is about to be kicked a bit early.  Result is
visible *especially* when the guest idling.

Timer proc *still* has to send to the channel (in order to kick PIT
and RTC logic), which takes time, and compensates a bit for possibly
early runs.

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.
