Package: libc6
Version: 2.9-13
Severity: important

Howdy!

This morning, I upgraded libc6 et al from 2.9-13 to 2.9-15. Immediately,
one of my unit tests began failing with a -1 return from signalfd():

14|***** Error (Invalid argument) in Signalfd(): Couldn't generate signalfd 
from -1/526336

with libc2.9-13, signalfd() returns a new file descriptor as expected.

I'm passing SFD_CLOEXEC|SFD_NONBLOCK (0x2004000), but the same behavior
is seen with either SFD_CLOEXEC or SFD_NONBLOCK (these are the only two
signalfd() flags described in the man page, last updated 2009-01-13).
With no flags passed, 2.9-15 works and creates the new signalfd.
