Jouni Malinen 63502c64e1 P2P: Fix P2P_CANCEL for p2p_in_invitation case
Commit f05cee9714 ('P2P: Clear
p2p_in_invitation on cancel') added a wpas_p2p_cancel() case to call
wpas_p2p_group_formation_failed() if wpa_s->p2p_in_invitation is set.
This is done in a loop going through wpa_s->next pointers. However, the
call here can result in removing the interface and freeing wpa_s. The
following attempt to read wpa_s->next is from freed memory and that can
result in process termination when using a separate P2P group interface
and issuing P2P_CANCEL on a group that was started through re-invocation
of a persistent group.

The recent commit 328f49acfe ('P2P:
Complete group formation on client data connection') "fixed" this by
accident since wpa_s->p2p_in_invitation gets cleared in the sequence
that could hit this issue and this results in P2P_CANCEL getting
rejected. However, the real bug here is in the loop that continues after
possible wpa_s instance deletion. Fix that by breaking out of the loop.

This package may include either wpa_supplicant, hostapd, or both. See
README file respective subdirectories (wpa_supplicant/README or
hostapd/README) for more details.

Source code files were moved around in v0.6.x releases and compared to
earlier releases, the programs are now built by first going to a
subdirectory (wpa_supplicant or hostapd) and creating build
configuration (.config) and running 'make' there (for Linux/BSD/cygwin
builds).
