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.
to solve the usb device enumeration race on boot, usbd creates /env/usbbusy
on startup and once all devices have been enumerated and readers have consumed
all the events, we remove the file so nusbrc/bootrc can continue. this makes
sure all the usb devices that where plugged in on boot are made available.
when opening a /env file ORCLOSE, and the process exits, envgrp() would
return nil can crash in envremove() because procexit will have set up->egrp
to nil before calling closefgrp().
the solution is to capture the environment on open, keeping a reference in
Chan.aux, so it doesnt matter on what process the close happens and a
env chan will always refer to its original environment group.
instead of checking addr+len >= addr, check len >= -addr so
that addr == 0 is never valid for len > 0 even if we decide
to have memory at the zero page so theres never any chance
user can pass in "nil" pointers.
put up some signs where we fall thru the switch cases in
fixfault()
sha256 is only defined for TLS1.2, however, technically, theres
no reason not to use it in TLS1.0/TLS1.1. the choice is up to
tlshand and pushtls, not the kernel.
listensrv() used to override Srv.end() with its own handler
to free the malloc'd Srv structure and close the fd. this
makes it impossible to register your own cleanup handler.
instead, we introduce the private Srv.free() handler that
is used by listensrv to register its cleanup code. Srv.free()
is called once all the srv procs have been exited and all
requests on that srv have been responded to while Srv.end()
is called once all the procs exited the srv loop regardless
of the requests still being in flight.
code assumed the accessdir() call would always mark the block dirty, but
this is not the case when noatime flag is enabled. this was reported by
michael in bug:
"open/with_noatime_option_cwfs_doesnt_preserve_changes_in_file_permissionowner"

introduce wificfg() function to convert ether->opt[] strings
to wifictl messages, which needs quoting for the value. so
etherX=type=iwl essid='something with spaces' works.
