store errno on the private process stack so its always per process
and not just per memory space. errno itself becomes a macro
dereferencing int *_errnoloc; which is initialized from main9.s
pointing to the private stack location.
various fixes in programs that just imported errno variable with
"extern int errno;" instead of including <errno.h>.
in ape close(), do the real filedescriptor _CLOSE() *after* we cleared
the _fdinfo[] slot because once closed, we dont own the slot anymore and
another process doing open() can trash the slot. make sure open() retuns
fd < OPEN_MAX.
double check in _startbuf() holding mux->lock if the fd is already buffered
preveting running double copyprocs on a fd.
dont zero the mux->rwant/ewant bitmaps at the end of select() as we do not
hold the mix->lock.
in _closebuf() kill copyproc while holding the mux->lock to make sure the
copyproc isnt holding it at the time it is killed. run kill() multiple times
to make sure the proc is gone.
python uses processes sharing memory. it requires at least fopen() to
be called by multiple threads at once so we introduce _IO_newfile()
which allocates the FILE structure slot under a lock.
diskparts fails on thinkpad x200 sdcard reader if we dont
give the unit some time to startup. the device took about
100ms to become ready so status poll loop with a long
timeout would be overkill.
1. Go group spotted that a slightly-obscured pointer move was done by AMOVL not AMOVQ.
2. Inspecting the code further, I noticed that other pointer types were set to TLONG not TIND,
causing similar truncation of pointers to 32 bits.
add PASS_MAX to limits.h for ape, and make getpass respect it. also increase the size of
the maximum passwords (we use long ones at work). Needed for native port of SVN (in progress).
the kernel would go into endless loop when stating "stats" and "ifstats"
files and the network interface having no connections, or otherwise return
wrong stat info.
the channel= plan9.ini parameter isnt needed anymore as we now
hop the channels to scan for beacons. the status is also indicated
with the link led :-)
handle all these flags on packet transmission like RTS for big
packets and sending data packets to the AP instead of broadcasting
everything.
properly setup bss hardware node table and filtering. now promisc
mode is only used when requested.
handle deauth message from ap.
increase node table to 32 entries.
Fix the behavior of exportfs -r.
Check the return of chdir(srv) to prevent exporting accidentally
the current working directory when the directory specified
with option -r doesn't exist.
Also fix at the same time the missing trailing \n in error
messages printed just before exits().
we gave wrong content-length in range requests. r->stop - r->start
is wrong because r->stop is the byte offset of the *last* byte, not
the *next* byte after the last.
Another band-aid fix to the usb mouse driver, to cope with a mouse which has
an interrupt endpoint number 3 but no number 1 or 2, and a report descriptor
more than 128 bytes long.
use the Srv.end callback for freeing the srv and closing the
file descriptor of a connection. this makes sure we wont free
the srv while there are still outstanding requests that would
access the srv when doing the respond() call.
we used to do getbuf() with nodata flag so it only worked when
we where lucky and got the same in memory block back. this
is uncritical once you have reamed the filesystem, its just
that sometimes ream would fail with "ream successfull, then
hjfs: fsinit: file ./hjfs not found".
in multithreaded programs, we have to wait until all outstanding
requests have been responded before closing down the srv.
dont make write errors sysfatal(), only print them. in case if
listensrv() is used we dont want to exit the process in respond()
called by some worker thread.
make sure Tversion is only handled when there are no outstanding
requests and make sure message size is sane.
on almost all machines, we get tons of these prints for pci busses that
are not physically there but are described in the ACPI namespace. the
reason that we enumerate these is because we do not enumerate _INI and _STA
methods to check if they are present. we just match the information with
the PCI devices we enumerated with our generic pci code. this works fine and
doesnt require aml code to poke arround in pci config space.
some controls are inverted. we reflect this by specifying
negative range in the volume table now and let genaudiovolread()
and genaudiovolwrite() do the conversion.
