b62b29ea87 Do not block on ctrl_iface monitor events
It looks like some of the global control interface cases ended up
blocking in sendmsg() when trying to send an event. Since this can block
all wpa_supplicant processing for multiple seconds, this is very
undesirable. Avoid this by requesting sendmsg() to return an error
rather than waiting for the message to be sent.

c4bf83a723 P2P: No duplicate AP-STA-CONNECTED/DISCONNECTED as global event
These events are sent as a special case to both the group interface and
"parent interface" (i.e., the interface that was used for managing P2P
negotiation). The latter is not really correct event, so get rid of it
with the new global control interface design where there is no need to
support legacy upper layer implementations.

47bfe49c31 Add wpa_msg_global() for global events
This function can be used instead of wpa_msg() and wpa_msg_ctrl() to
indicate that an event is not specific to a network interface.

214e428b42 Allow global ctrl_iface monitors
The ATTACH/DETACH mechanism to request event messages from
wpa_supplicant can now be used through the global control interface,
too. This results in events from all interfaces being delivered through
a single monitor socket. "IFNAME=<ifname> " prefix is used on events
that are specific to an interface.

d2a9e2c76d Abstract and Android sockets for global ctrl_iface
The wpa_supplicant global control interface parameter can now be used to
explicitly specify an abstract UNIX domain socket (Linux specific
extension) with "@abstract:" prefix and an Android control socket with
"@android:" prefix.

d49ea68284 Android: Force group access to ctrl_iface directory
wpa_supplicant is started from /init.*.rc on Android and that seems
to be using umask 0077 which would leave the control interface
directory without group access. This breaks things since Wi-Fi
framework assumes that this directory can be accessed by other
applications in the wifi group. Fix this by adding group access even
if umask value would prevent this.

In most cases, this issue was not hit since the control interface
directory is normally created by that same init.*.rc file with suitable
mode and wpa_supplicant is killed in the way that does not allow it to
remove the file. However, if wpa_supplicant is allowed stop cleanly, it
will remove the directory and the next start could result with the Wi-Fi
framework not being able to use Wi-Fi (and GUI not showing Wi-Fi getting
enabled).

6700a277a9 Avoid dropping ctrl_iface on ENOBUFS error burst
These bursts can result in control interface monitors being detached
even if the external program is still working properly. Use much larger
error threshold for ENOBUFS to avoid this.

3fd2a226f9 wpa_supplicant: Fix ctrl_interface group permissions to allow read/execute
When using umask 0077, the control interface directory was left without
group read/execute permissions even if the configuration file explicitly
asked for the group to be allowed to access the control interface. Fix
this by adding read/execute permissions for group if a specific group is
defined in the configuration. [Bug 199]

19b9436c0e Fix UNIX domain socket address handling to be more portable
Removing just sun_family is not portable since some systems (e.g.,

portable. In addition, set sun_ken for FreeBSD.
