Re: [9fans] Backgrounding a task
“window -m cmd” will run the command in the same namespace, forked, but in new window. “-m” is for “mount”, an alternative way of communication with the window system to /dev/wctl which is default.

[9fans] Fontsrv
A backport of fontsrv from p9p to Plan 9 is almost complete, based on an earlier port of freetype library found at mirtchovski.com. Besides TTFs, it happens to render most of the Type 1 fonts already there, enabling their use in devdraw programs. Coming soon. - Yaroslav

[9fans] u9fs(4) misuses Fcall.afid in its p9any authentication module
U9fs(4) misuses Fcall.afid in its p9any authentication module.
The afid field of Fcall structure is only valid with Tauth or Tattach.
Tread, Twrite, Tclunk should use rx-fid instead. It's been lucky so
far to get the job done because rx-afid survives from previous
Tauth/Tattach. The issue pops up when several authentications happen
concurrently.
Test case:
u9fs = 'host with u9fs on tcp!*!564'
9fs $u9fs; for(i in 1 2 3 4 5 6 7 8){ 9fs $u9fs }; wait
Should:
no errors
Should not:

BTW, this change was after http://9fans.net/archive/2011/10/157 which

Re-build of 9xenpccpuf, the PV Xen guest kernel built from sources at /n/sources/xen/xen3/9), with latest changes in sys/src/9/port/, sys/src/libc/ and others - resulted in non-functional kernel: it dies on boot with attached diagnostics. I haven't looked further yet. attachment: xen.png

Re: [9fans] mallocz in APE
Replacing _MALLOCZ back with mallocz within APE realm seems to me a better option to consider. I don't think this is better. APE generally tries very hard to be compliant to the spirit of ANSI (or POSIX with _POSIX_EXTENSION defined), this includes not poluting the namespace with plan9isms where possible. Having said this what about setmalloctag() getcallerpc(), etc etc. It is internal to the libraries and is not exposed to the APE apps, right?

Re: [9fans] Fsctotum per user instances?
Not exactly. Please refer to /sys/doc/auth.ps | http://plan9.bell-labs.com/sys/doc/auth.html for overview of the architecture. So the incoming authentication is handled by the cpu owner factotum? That means the authentication information is held by the cpu owner factotum and the user factotum just handles the users keys? And the user factotum is run after authentication.

[9fans] APE libsec

Re: [9fans] Mercurial and Plan 9
We have problems with threading support in the mentioned APE python port (e.g. hg serve): they complain about invalid file descriptors which may be due to non-reentrant implementation of APE interfaces. I didn't look any deeper though. 2013/1/5 Federico G. Benavento benave...@gmail.com: Hola Steven, thanks for getting mercurial support for Plan 9 upstream, I did the APE port of python (based on the native one) years ago because nothing worked with the native one, I wanted to get X running then it needed openssl or some socket api that wasn't implemented in the Plan 9 emulation of it (written in python as charles mentions), because native python didn't have sockets and things like non-blocking IO provided by APE's select. basically you're left out with the Language but without significant parts of the runtime when you use a native port. thanks again On Jan 4, 2013, at 8:10 PM, Steven Stallion sstall...@gmail.com wrote: Hi Jeff, Mercurial has been taken care of!

[9fans] bug in topng(1)
There's a bug in topng(1) which under certain circumstances may result in broken output image. When such an image then is fed to png(1) diagnostics like the following are produced: term% png /tmp/1.png png: unknown filtering scheme 49 (The filtering scheme number may differ.) This happens when at the beginning of an input line (z-x == 0) there are only room for exactly one pixel in output buffer (b+pixwids == e), at /sys/src/cmd/jpg/writepng.c:/^zread/+/while/. Since every scan line should start with a filter algorithm ID it consumes a byte in the buffer, leaving no room for the pixel. The pixels variable turns zero, no pixels are emitted, yet the alg byte slips out. During next run of zread() with empty buffer, the alg byte is emitted again, causing permanent skew of output bytes. The proposed fix is to modify the loop condition so the loop won't proceed if there are not enough room for at least one pixel plus a byte for the filter alg ID. Submitted /n/sources/patch/topng-extrabyte/. - yk

[9fans] APE rename: wstat for 'none'
Is there a specific reason of forbidding wstat for 'none' in fossil (/sys/src/cmd/fossil/9p.c:130,133)? This causes APE rename() to fail almost always (/sys/src/ape/lib/ap/plan9/rename.c:43) Perhaps rename() should be fixed to match mv (/sys/src/cmd/mv.c:/^mv1) to go around this? -- - Yaroslav
Re: [9fans] APE rename: wstat for 'none'
why is this related to ape? if you are none, then you are limited as to what you can do on the file server. you may just have an auth problem. APE implements rename() in terms of wstat or copying. It's just doesn't try to work around failing wstat (that's perhaps a good thing) while mv does. There are no auth problem since I deliberatly run the python web app as none, not willing to give it eve's powers.

Re: [9fans] APE rename: wstat for 'none'
no, i didn't. ratrace doesn't run if you're none. try 'ratrace -c auth/none cmd ...' while not being none and ignore everything preceding Exec cmd. as i understand it, your claim is that mv works as none but ape/rename does not and this is because ape/rename uses wstat. both use wstat or copying; what's different is how they choose what to use. mv falls back to copying if wstat fails; ape/rename does not.
Re: [9fans] APE rename: wstat for 'none'
oh, i thought you were comparing system/library calls, not library function vs program. i don't understand that comparison. it so happens that mv is a program with own idea how to do renames, and there are no other obvious subject to compare with.

Primarily DVI, but also observed with VGA.

Re: [9fans] rc: fn name @{block}
you've misunderstood the current grammar. you have defined 2 functions
name and '@' as {block}. the binding, illustrated with parens is
fn (name @) {block}
the production in the grammer is
FN words brace
but since once production for words is words - keyword, a keyword
is a valid function name.
Then, how would you explain this:
term% fn x @{x=y}
term% whatis x
fn x {x=y}
term% fn 'x @'{x=y}
term% whatis 'x @'
fn 'x @' {x=y}
Re: [9fans] rc: fn name @{block}
term% fn x @{x=y}
term% whatis x
fn x {x=y}
creates to functions x and '@' definition {x=y}.
The question is why it discards @ here?
Re: [9fans] nfactotum: mschap fix
surely you need to use the user attribute. if you don't please send

The user attribute is available at the end of CR protocol, upon 'attr'
rpc request.
The attached chap.c compiles cleanly here.

Erik's point is that rc isn't discarding it. You have a list. It sets x
equal to that function, then sets @ equal to that same function.

fn x {x=y}

Re: [9fans] Regarding 9p based protocols message framing
Perhaps initially: over an IP network, 9P used to run over IL. still does, including on the system i'm sending this from. What advantages does it have over TCP? Does it worths the effort of tailoring it back in, esp. for a fossil/venti site? -- - Yaroslav
Re: [9fans] Regarding 9p based protocols message framing
Why was I puzzled: because as a non Plan9 user / developer, I usually think of the underlaying transport technology (be it sockets or 9p) as a stream of bytes without explicit framing. As I understand, 9P itself is designed to operate on top of a message-oriented transport; however, it has everything required to run over a stream, esp. message length at beginning of every message. Framing is done by the library: the read9pmsg routine performs as many reads as necessary to return a complete 9P message to the caller.

Does fossil need to be repopulated, an O(n) operation, or does it act merely as a cache that gets cold? (an O(1) operation). Fossil is a write cache for venti - the blocks in the archival snapshots are moved to Venti. Read requests are proxied for venti. Recovery means initializing the filesystem using the given vac scrore, with no implied data transfer - blocks are copied-on-write. -- - Yaroslav

[9fans] p9any auth in u9fs: uid value in ticked is ignored
There is a security problem with p9auth in u9fs: it uses uname from
Tauth/Tattach as user's identity - ignoring the user id which has been
authenticated to the auth server. As uname is always set to up-user
in devmnt, this means that:
a) a user cann't have a different name on the u9fs machine; and, more
serious,
b) a user can easily masquerade as another user to u9fs by simply
booting his terminal under that user while using own credentials for
optaining the ticket.
A proposed fix has been submitted as /n/sources/patch/u9fs-p9sk1:
/n/dump/2011/1010/sys/src/cmd/unix/u9fs/authp9any.c:369,375 -
/sys/src/cmd/unix/u9fs/authp9any.c:369,378
fprint(2, p9anyattach: afid %d state %d\n, rx-afid,
sp-state);
if (sp-state == Established strcmp(rx-uname, sp-uname) == 0
strcmp(rx-aname, sp-aname) == 0)
+ {
+ rx-uname = sp-t.suid;
return nil;
+ }
return authentication failed;
}
Whether to use t.suid or t.cuid as the target uid remains an open
question: authsrv(6) says t.suid represents target uid; the real use,
howerver, is not that clear: cwfs for 9p2k uses t.suid; while fossil,
exportfs, cpu -R and cwfs for old9p check against t.cuid. Comments in
/sys/include/authsrv.h:58,76 appear somewhat opaque until authsrv(6)
and p9sk1 client/server code in factotum are carefully studied.

Re: [9fans] p9any auth in u9fs: uid value in ticked is ignored
devmnt always uses up-user for Tauth/Tattach no matter what an auth protocol would yield (/sys/src/9/port/devmnt.c:281). Stock 9P servers tolerate this and check Tattach.uname to match Tauth.uname but use t.cuid or t.suid as the true user identity (unless no auth required). Anyway, simply trusting Tattach.uname is too naïve - at least for p9any. It's true that the server must take account of the result of authentication, but although that might not mean identity, the results of authentication should be consistent with the name presented as uname in Tauth/Tattach. In the context of p9auth I think that means that the cuid of AuthInfo should match.
Re: [9fans] p9any auth in u9fs: uid value in ticked is ignored
Uname in Tauth/Tattach indeed seem to be irrelevant for p9any but as it is external to 9P this may be a provision for other possible auth schemes where the uname may be the only place to provide an indentity being authenticated...

I am pretty sure this has worked for several years but now it is broken: Has mac-owner's key been expired in your auth keyfs? Are you all happy to sprinkle bootes key onto unix machines (hard to believe)? negative: the credentials you put in /etc/u9fs.key represent the service, not a client. A client may be any valid user registered in the AS. U9fs uses its key to decrypt tickets issued by the AS to clients.

which rather requires ideal circumstances for correct behaviour.
partial installs are easy to recover from. i just used it friday to sort
out a file system that had a contrib package listed as installed, but it
hadn't been.
It *would* be easy if contrib(1) properly indicated the install status
of a package. As it is right now, contrib/install marks a package as
installed and THEN goes about installing it. If anything fails, the
install will still be marked as having been successful. A subsequent
contrib/install for the same package will snubly claim that the package
has already been installed and refuse to run. You have to supply the
'-f' switch to make the install complete. However, doing this requires
(1) knowing that the install broke, and (2) that all the packages
dependencies have been met (because -f also overrides dependency
checking). contrib(1) doesn't provide any way to check if a package is
up to date, like replica/changes. Having a contrib(1) wrapper for
replica/changes (say, 'contrib/changes') would be very handy. (And
simple to write.)
As for prematurely marking packages as successfully installed...
This:
cat $cfg !
...
exec /bin/contrib/pull $name
should probably be replaced with something like:
cat $cfg.part !
...
/bin/contrib/pull $name
if(~ -$status -) mv $cfg.part $cfg
if not {
echo install failed [1=2]
rm $cfg.part
