Bug 0000833: SOCK_* flags in getaddrinfo hints->ai_socktype Accepted as Marked
http://austingroupbugs.net/view.php?id=833

This item has been tagged for Issue 8.
The changes for this issue have been included in the updated fix for 0000411.

The additional changes to the Desired Action for 411 are (all line numbers relative to Issue 7):

Change P383 L12865:
The <sys/socket.h> header shall define the following symbolic
constants with distinct values:
to

The <sys/socket.h> header shall define the following socket
types (see [xref to XSH 2.10.6]) as symbolic constants with
distinct values:

At the current text in bug 411 under the heading "After line 12869 [XBD <sys/socket.h>]", change:

The header shall define the following symbolic constants with
values that are bitwise distinct from each other and from the
preceding SOCK_* constants:

to:

Implementations may provide additional socket types.

The header shall define the following socket flags, for use in
socket(), socketpair(), and accept4(). These flags shall be
symbolic constants with values that are bitwise distinct from
each other and from all SOCK_* constants representing socket
types:

After the current text in bug 411 added under the heading " After line 19395 [XSH accept DESCRIPTION], add the following:" add an additional paragraph:

Implementations may define additional flags.

After the current text in bug 411 under the heading "After line 62515 [XSH socket DESCRIPTION], add the following:

Implementations may define additional flags.

After the current text in bug 411 under the heading "After line 62586 [XSH socketpair DESCRIPTION], add the following:

Implementations may define additional flags.

Add to APPLICATION USAGE in freeaddrinfo() after P920, L30800:

The [I]ai_socktype[/I] field pointed to by hints is just the
socket type; not the socket type and flags that can be specified
when the socket is created.

At page 917, line 30691, change

as defined in socket()

to

as defined in [xref to 2.10.6]


Eric took an action to merge the changes into one document and attach it as
an ODT and a PDF to bug 411, as they are too long to go in a note.

it easier to se the full set of changes

http://austingroupbugs.net/view.php?id=411

I noticed that the attachment has an improvement to the changes for
posix_spawn_file_actions_adddup2() over what's in the original Desired
Action.

You are correct - I reworded that section as part of formatting things,
when I realized that the old wording was unclear on whether FD_CLOEXEC
remains set or must be cleared on fildes in the parent process (the
intent was that FD_CLOEXEC in the parent is never altered, but the child
can inherit the fd in spite of the parent's setting). I guess I could
have been more obvious about the change, rather than relying on the
review process, but I'm glad you caught it. As penance, I've added a
comment to the note explaining that action.

I like the new version, and I think we should change the Final Accepted
Text field to point to the attachment, to make the update official.

Sounds like something to discuss at the next meeting :)
