Hi,

I think since this commit:
--------
commit 7c721d31e4b7a0bdf6f803b8e7c38996bf60b59f
Author: Bernhard Reutner-Fischer <[email protected]>
Date:   Sun Jan 29 17:48:54 2012 +0100

    tmpnam, tempnam are obsolete in SUSV4

---------

the test case is broken. mkstemp opens the temporary file, mktemp
does not.

Strace shows following issue:
socket(PF_FILE, SOCK_STREAM, 0)         = 3
getpid()                                = 12607
open("/tmp/tst-cancel4-socket-1-9PTGfr", O_RDWR|O_CREAT|O_EXCL, 0600) = 4
close(4)                                = 0
bind(3, {sa_family=AF_FILE, path="/tmp/tst-cancel4-socket-1-9PTGfr"}, 35) = -1 EADDRINUSE
(Address already in use)
open("/tmp/tst-cancel4-socket-1-cHm3px", O_RDWR|O_CREAT|O_EXCL, 0600) = 4
close(4)                                = 0
bind(3, {sa_family=AF_FILE, path="/tmp/tst-cancel4-socket-1-cHm3px"}, 35) = -1 EADDRINUSE
(Address already in use)

mkstemp() creates the file, and bind() returns EADDRINUSE, if the 
file already exists.

Return to mktemp usage as glibc does for this testcase?

best regards
