with window -m, properly remove the old wsys from /dev before
binding new window to it, so the original window wont leak
into the new namespace.
do not pass -pid when $wsys does not refer to a local running rio.
cleanup environment before running sub-process.
set window label consistentently no matter if -m is used or not.

add new functions pageaddr() that returns a string describing
the page to be loaded. it is in the form of:
/path/to/file!pagename!subpage!....
one can jump to such a page by calling trywalk(name, addr)
where name and addr get concatinated with ! to form a page
address and then the currently loaded pages are walked up
to the nearest page which is then returned. (or nil when
not found). the remaining address will be set in the global
pagewalk variable.
once pages get loaded (asynchronously), pagewalk1() gets
called again on addpage() and continues the walking up to the
last page.
new program flag -j <addr> was added to jump to a page on
startup.
page address (without filename) can also be supplied in
plumb message with the "addr" attribute.

rio looks backwards in the line for the beginning of a filename
that needs to be completed with ^F. this change makes the
characters: =, ^, ( and { stoppers, so filename completion
will work in all these cases:
foobar=/foo/ba^F; for(i in (fo^F ba^F)){/bin/baz^F
this means completion will not work for prefixes having these
special characters in them.
thanks to burnzez for bringing it up.

the alloc and realloc tag words do not start at the beginning of
a block created by mallocalign(). instead, the block is padded
with ALIGN_MAGIC.

dont spam the console with qfull warnings. this makes things worse.
handle loopback packets as stated in the comment. we call etheriq()
with fromwire=1 for loopback packets so etheriq() can pass the packet
on (without copying) or free it. dont inhibit interrupts while calling
etheriq(). etheriq() can safely be called from process and interrupt
context. it is unclear what this was supposed to fix and testing didnt
seem to have any odd effects.

stack buffer limit
(11:02:29 PM) me: why is buf in /sys/src/9/port/devssl.c:/^sslwrite only 128 bytes?
(11:02:58 PM) me: it makes it so you can't use a 128 bytes secret as negotiated by infauth in a secretin or secretout ctl message
(11:03:30 PM) me: which in turn means you can't use such a secret with pushssl(2)
(11:06:15 PM) me: inferno's sslwrite is limited to 32 bytes, but its ssl library writes to the secret files instead of to the ctl file
(11:08:50 PM) mischief: what should it be instead of 128 bytes
(11:08:58 PM) me: larger
(11:09:16 PM) mischief: how about 129 bytes?
(11:09:59 PM) me: also broken in 9front, by the way
(11:15:14 PM) me: i guess it should be replaced with parsecmd

get rid of the service buffer limit. keep service buffers
on a global freelist protected by lock.
dont fatal when we hit the process limit. instead, just
abort the rpc with an error.
handle rendezvous() interrupts.

when a replicated source image with a clipr with clipr.min > Pt(0, 0),
drawclip() would properly translate the src->clipr on the dstr
but then clamp the source rectangle back on src->r.
while traversing down multiple layers, this would cause the translation to
be applied multiple times to the dst rectangle giving the wrong image result.
this change adds a new drawclipnorepl() function that avoids the clamping
of source and mask rectangles to src->r and mask->r. this is then used in
libmemlayer.
the final memimagedraw() call will call drawclip() which will do the final
claming.
a testcase is provided:
#include <u.h>
#include <libc.h>
#include <draw.h>
Image *blue;
Image *red;
void
main(int, char *argv[])
{
Image *i;
if(initdraw(nil, nil, argv[0]) < 0)
sysfatal("initdraw: %r");
i = allocimage(display, screen->r, screen->chan, 1, DWhite);
red = allocimage(display, Rect(0,0,1,1), screen->chan, 1, DRed);
blue = allocimage(display, Rect(0,0,1,1), screen->chan, 1, DPaleblue);
replclipr(red, 1, Rect(10, 10, 110, 110));
replclipr(blue, 1, Rect(11, 11, 111, 111));
/* draw on non-layer, works correctly */
draw(i, i->r, red, nil, ZP);
draw(i, i->r, blue, nil, ZP);
draw(screen, screen->r, i, nil, i->r.min);
flushimage(display, 1);
/* draw on (screen) layer is too far to the right */
draw(screen, screen->r, red, nil, ZP);
draw(screen, screen->r, blue, nil, ZP);
flushimage(display, 1);
for(;;){
sleep(1000);
}
}

the nt blob ends with 4 zero bytes, this is not the same as
the EOL av-pair terminator!
this makes ntlmv2 work with windows xp with LmCompatibityLevel = 3

extending factotums and the auth servers mschap implementation
to handle variable length NT response for NTLMv2.
fix some minor bugs.
only tested with cifs so far.

procs
replaced the p->pid != 0 check with up->parentpid != 0 so
p->pid == up->parentpid is never true for p->pid == 0.
avoid allocating the wait records when up->parentpid == 0.
|
|
theres a race when we wait for a process children and that
process exits before we sleep().
|
|
when a process got forked with RFNOWAIT, its p->parent will still
point to the parent process, but its p->parentpid == 0.
this causes the "parent still alive" check in pexit to get confused
as it only checked p->pid == up->parentpid. this condition is *TRUE*
in the case of RFNOWAIT when the parent process is actually dead
(p->pid == 0) so we attached the wait structure to the dead parent
leaking the memory.

we dont have to
we do not need to wait for fork/execed program to finish when
not collecting waitmsg. this reduces the number of rio
processes hanging arround for each window shell just waiting
for it to terminate and then dumping the waitmsg.

patch/u9fs-afid)
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:
mount failed: authentication failed

we might get a unreachable nameserver ip from a parent
nameserver. if the remaining set of nameservers does not
loop, we should try to resolve them.
so skip the loopcheck for nameservers already tried.

validurl() is just used to check if the string is a full
absolute url with a protocol scheme. we do not have to
match the host part *exactly*, only if there is *something*
in the hostpart.
|
|
the wire
we'd like to keep Url.host in unicode for factotum key
lookup. only when we send the url in a request, we have
to convert it to ascii.
