* General news
Feedback on the 9945 Project Editor report and the Austin Group OR
report for ISO was discussed.It was agreed that Andrew will omit
the detailed wording on the anticipated major revision date and
submit. The two reports are available in the document register
as Austin/664 (OR Report) and Austin/665 (PE Report).
Progress of the IEEE PASC approval of the draft text of a Project
Authorization Request and the accompanying PMC evaluation criteria
for TC2 has stalled, while some procedural issues related to SEC
membership are resolved.

+Bug 0000658: Undefined/unspecified behavior clauses in description of
open have race conditions OPEN
http://austingroupbugs.net/view.php?id=658

action to update the proposal to resolve the overlaps appropriately.
+Bug 0000615: pthread_setcancelstate should be async-signal-safe OPEN
http://austingroupbugs.net/view.php?id=615
We now have reports on AIX and Apple. Jim to report back on whether

OPEN
http://austingroupbugs.net/view.php?id=672
Geoff has a new proposed resolution in note 1618. Decided to solicit input
from FS developers. Eric to go to Linux, David to AIX and Jim to Solaris.
Jim has completed his action (see bugnote 1691).
Andrew should chase HP and Apple for input.

http://austingroupbugs.net/view.php?id=663

Bug #850: Standardize MAP_ANON Accepted as Marked
http://austingroupbugs.net/view.php?id=850
This item is tagged for Issue 8
On page 37 after line 1195 (XBD 3.15 definition of Angle Brackets),
add a new section (and renumber subsequent entries as appropriate):
3.16 Anonymous Memory Object
An object that represents memory not associated with any
other memory objects.
On page 68 after line 1972 (XBD 3.22 definition of Memory Object), add:
An anonymous memory object (see Section 3.16 on page 37).
On page 372 after line 12515 (XBD <sys/mman.h> description), add:
MAP_ANON
Synonym for MAP_ANONYMOUS. MAP_ANON shall have the same
value as MAP_ANONYMOUS.
MAP_ANONYMOUS
Map anonymous memory.
On page 1322 after line 43724 (XSH mmap() description), add:
Anonymous memory objects.
On page 1322 line 43730 (XSH mmap() description) change:
The mmap() function shall establish a mapping between the address
space of the process at an address pa for len bytes to the
memory object represented by the file descriptor fildes at
offset off for len bytes.
to:
The mmap() function shall establish a mapping between the address
space of the process at an address pa for len bytes to the
memory object represented by the file descriptor fildes at
offset off for len bytes, or to an anonymous memory object of
len bytes.
On page 1323 after line 43773 (XSH mmap() description, table about
MAP_* symbolic constants), add two new rows:
MAP_ANON | Synonym for MAP_ANONYMOUS.
MAP_ANONYMOUS | Map anonymous memory.
On page 1324 after line 43823 (XSH mmap() description), add a new paragraph:
If MAP_ANONYMOUS (or its synonym MAP_ANON) is specified, fildes
is -1, and off is 0, then mmap() shall ignore fildes and instead
establish a mapping to a new anonymous memory object of size
len. The effect of specifying MAP_ANONYMOUS (or MAP_ANON) with
other values of fildes or off is unspecified. Anonymous memory
objects shall be initialized to all bits zero.
On page 1325 lines 43881-43882 change:
[ENXIO]
MAP_FIXED was specified in flags and the combination of
addr, len, and off is invalid for the object specified by
fildes.
to:
[ENXIO]
MAP_FIXED was specified in flags and the combination of
addr, len, and off is invalid for the specified object.
Add before page 1326 line 43887:
In addition, if MAP_ANONYMOUS (or MAP_ANON) is not set in flags,
the mmap() function shall fail if:
and then move the EACCES, EBADF, ENODEV and EOVERFLOW errors, and
the first ENXIO error (line 43880), to after this new text.
On page 1328 after line 43989 (XSH mmap() rationale), add a new paragraph:
Some historical implementations only supported MAP_ANON, some
only supported MAP_ANONYMOUS, and some supported both spellings.
This standard includes both spellings partly for application
compatibility and partly because neither spelling was clearly
more popular than the other at the time this feature was
considered for standardization.
On page 1365 lines 45154-45155 (XSH msync() description) change:
[SHM|TYM]The effect of msync() on a shared memory object or a
typed memory object is unspecified.[/]
to:
The effect of msync() on an anonymous memory object, [SHM]shared
memory object[/], or [TYM]typed memory object[/] is unspecified.
Bug #851: pthread_atfork orphans handlers in unloaded shared libraries OPEN
http://www.austingroupbugs.net/view.php?id=851
Discussion started on this item, and will resume next time.
