Bug#617973: libc6-dev: wrong SOCK_CLOEXEC on hppa causes udev startup to fail and boot fails

[Meelis Roos <mroos@linux.ee>]

Package: libc6-dev
Version: 2.11.2-10
Severity: important


While debugging #617967 (udev fails to start on hppa and breaks boot) it came out that
SOCK_CLOEXEC is defined wrong on hppa. Namely, asm-generic has O_CLOEXEC 020000000 and
SOCK_CLOEXEC is defined to that value. In addition, SOCK_CLOEXEC is unconditionally
redefined in bits/socket.h enum to 020000000 independent on the value of O_CLOEXEC.
This works fine while O_CLOEXEC is 020000000 like on most architectures. But on
hppa, O_CLOEXEC is defined to be 010000000 but SOCK_CLOEXEC does not change.

This makes udev's socket(PF_NETLINK, SOCK_DGAM|SOCK_CLOEXEC, ...) use invalid flag for
SOCK_CLOEXEC and socket call fails with EINVAL, breaking udev startup and machine bootup.
