the ini buffer was not reset when we got eof in the message
body read causing a endless loop. instead of defining our
own read9pmsg() function, just handle the first read specially
when we consumed the first 4 bytes for the "impo" protocol
escape check.
this code was if(0) for a long time due to wrong parentesis,
fixed parentesis cause print spam on some machines making them
unusage (kenji okomoto). removing the check alltogether.
theres a bootstrap problem:
when /bin/init is run, it processes /lib/namespace where we might want to
mount or bind resources to /n or /mnt. but mntgen was run later in
cpurc/termrc so these mounts would be ignored.
we already have mntgen in bootfs, so we can provide these mountpoints early.
i keep the termrc/cpurc mntgens where they are, but ignore the error
prints. this way old kernels will continue to work.
When a window is moved or reshaped, that implicitely tops
the window and makes it current. The conseqence of this
is that we always have to redraw the window as if it where
a current window in any case. This was handled for Reshaped
windows, but not when the window was just moved. We now
handle both cases the exact same way, getting rid of the
Moved wctl message.
make kbdproc() and mouseproc() share fd table with the main proc
and not explicitely close the file descriptors. so /dev/mouse gets
closed *after* /dev/draw/new to avoid the white window refresh issue.
apparently, this causes some quadcore ramnode vm to hang on boot,
even tho all cores successfully started up and are operational.
i suspect some side effect from timersinit()... this would also
mean *notsc= would break it (syncclock() would continue)...
its unclear.
i'm reverting this for now until the problem is better understood.
when testing in qemu, launching each ap became slower and slower
because all the ap's where spinning in syncclock() waiting for
cpu0 to update its mach0->tscticks, which happens only much later
after all cpu's have been started up.
now we wait for each cpu to do its timer callibration and
manually update our tscticks while we wait and each cpu will
not spin but halt while waiting for active.thunderbirdsarego.
this reduces the system load and noise for timer callibration
and makes the mp startup linear with regard to the number of
cores.
the shared command language assumed 512 byte sectors, which is
not the case for fdisk as it uses cylinders for the block unit.
so we introduce an extra argument in the Edit structure and
parseexpr() function so byte sizes are properly converted to
the block unit when the K,M,G and T postfixes are used.
the pcap files produced by snoopy had the wrong timestamps because it expected:
/* magic=0xa1b2c3d4 */
ulong ts_sec; /* seconds*/
ulong ts_usec; /* microseconds */
but we wrote:
uvlong ts; /* nanoseconds */
now, we write:
/* magic=0xa1b23c4d */
ulong ts_sec; /* seconds */
ulong ts_nsec; /* nanoseconds */

instead of testing for special field primes each time in mpmod(),
make it explicit with a mpfiled() function that tests a modulus N
to be of some special form that can be reduced more efficiently with
some precalculation, and replaces N with a Mfield* when it can. the
Mfield*'s are recognized by mpmod() as they have the MPfield flag
set and provide a function pointer that executes the fast reduction.
as the generated parser intermixes lines from .y source
and the parser text, the line source/lineno for yyparse()
shows up wrong in the debugger. to make stack traces a
bit less crazy, put a #line 1 "/sys/lib/yaccpar" before
copying in the parser text.
introduce cpushutdown() function that does the common
operation of initiating shutdown, returning once all
cpu's got the message and are about to shutdown. this
avoids duplicated code which isnt really machine specific.
automatic reboot on panic only when *debug= is not set
and the machine is a cpu server or has no display,
otherwise just hang.
chacha20 comes in two variants: ietf rfc7539, using 96 bit iv and 32 bit counter
and draft-agl-tls-chacha20poly1305 using 64 bit iv and a 64 bit counter. so
setupChachastate() now takes a ivlen argument which sets the mode.
add ccpoly_encrypt()/ccpoly_decrypt() routines.
to implement timing safe ccpoly_decrypt(), a constant time memcmp was needed, so
adding tsmemcmp() to libsec.
when the "resize" wctl was used on a hidden window, the window
was put back on the screen, however, it was not removed from
the hidden[] array so trying to hide the window again failed
because whide() assumed it was already hidden.
the fix is to not unhide the window, but preserve the hidden
state, so windows can programmatically be reshaped and moved,
but will remain hidden unless explicitely unhidden.
