_GNU_SOURCE to be defined for systems that need it (like glibc ones.)
be sure to find the right config.h for host programs.
these fixes combined make builds on debian 7 complete for me.
Many of the global configuration parameters are written as strings
without filtering and if there is an embedded newline character in the
value, unexpected configuration file data might be written.
This fixes an issue where wpa_supplicant could have updated the
configuration file global parameter with arbitrary data from the control
interface or D-Bus interface. While those interfaces are supposed to be
accessible only for trusted users/applications, it may be possible that
an untrusted user has access to a management software component that
does not validate the value of a parameter before passing it to
wpa_supplicant.
This could allow such an untrusted user to inject almost arbitrary data
into the configuration file. Such configuration file could result in
wpa_supplicant trying to load a library (e.g., opensc_engine_path,
pkcs11_engine_path, pkcs11_module_path, load_dynamic_eap) from user
controlled location when starting again. This would allow code from that
library to be executed under the wpa_supplicant process privileges.
Most of the cred block parameters are written as strings without
filtering and if there is an embedded newline character in the value,
unexpected configuration file data might be written.
This fixes an issue where wpa_supplicant could have updated the
configuration file cred parameter with arbitrary data from the control
interface or D-Bus interface. While those interfaces are supposed to be
accessible only for trusted users/applications, it may be possible that
an untrusted user has access to a management software component that
does not validate the credential value before passing it to
wpa_supplicant.
This could allow such an untrusted user to inject almost arbitrary data
into the configuration file. Such configuration file could result in
wpa_supplicant trying to load a library (e.g., opensc_engine_path,
pkcs11_engine_path, pkcs11_module_path, load_dynamic_eap) from user
controlled location when starting again. This would allow code from that
library to be executed under the wpa_supplicant process privileges.
Spurious newlines output while writing the config file can corrupt the
wpa_supplicant configuration. Avoid writing these for the network block
parameters. This is a generic filter that cover cases that may not have
been explicitly addressed with a more specific commit to avoid control
characters in the psk parameter.
WPA/WPA2-Personal passphrase is not allowed to include control
characters. Reject a passphrase configuration attempt if that passphrase
includes an invalid passphrase.
This fixes an issue where wpa_supplicant could have updated the
configuration file psk parameter with arbitrary data from the control
interface or D-Bus interface. While those interfaces are supposed to be
accessible only for trusted users/applications, it may be possible that
an untrusted user has access to a management software component that
does not validate the passphrase value before passing it to
wpa_supplicant.
This could allow such an untrusted user to inject up to 63 characters of
almost arbitrary data into the configuration file. Such configuration
file could result in wpa_supplicant trying to load a library (e.g.,
opensc_engine_path, pkcs11_engine_path, pkcs11_module_path,
load_dynamic_eap) from user controlled location when starting again.
This would allow code from that library to be executed under the
wpa_supplicant process privileges.
WPA/WPA2-Personal passphrase is not allowed to include control
characters. Reject a Credential received from a WPS Registrar both as
STA (Credential) and AP (AP Settings) if the credential is for WPAPSK or
WPA2PSK authentication type and includes an invalid passphrase.
This fixes an issue where hostapd or wpa_supplicant could have updated
the configuration file PSK/passphrase parameter with arbitrary data from
an external device (Registrar) that may not be fully trusted. Should
such data include a newline character, the resulting configuration file
could become invalid and fail to be parsed.

in that we use lp_lwpid as an input to say which lwp to operate on.
freebsd passes the lwpid as the pid, which works fine there
since freebsd has globally unique LWP IDs which are also distinct
from process IDs. the libproc interface that uses this ptrace() call
is only supposed to return info for the process's representative LWP,
so just initialize pl_lwpid to 1 before using it.
for the object and symbol rather than the freebsd names.
remove the lookups of the preinit and dlactivity hooks
(which do not currently exist separately in rtld on netbsd) for now
since this rtld_db implementation does not report those events anyway.
