These verify that a proper pointer type is used and in addition, seems
to get rid of some false static analyzer warnings.
Signed-hostap: Jouni Malinen <j@w1.fi>
Use an explicit pointer to the beginning of the buffer and a flag
to indicate whether that is to external data or not. This avoids
a branch whenever accessing the buffer and helps some static
analyzers to understand the wpabuf memory uses better.

This function can be used as a wrapper for os_realloc(ptr, nmemb * size)
when a reallocation is used for an array. The main benefit over
os_realloc() is in having an extra check to catch integer overflows in
multiplication. This is similar to the os_zalloc() to os_calloc() move.

The new ssid2 parameter can be used as an alternative mechanism for
configuring SSID for hostapd. It uses the same formats that
wpa_supplicant uses in the configuration file for strings.

Instead of masking out non-ASCII characters with underscores, espace the
SSID data using rules compatible with printf.
Signed-hostap: Jouni Malinen <j@w1.fi>
This can be used to build ASCII strings from binary data that is
more likely to use ASCII (i.e., text format is more natural
option than hexdump, but there is possibility of some non-ASCII
characters).

This new mechanism can be used to make wpa_supplicant using external
storage (e.g., key store in the operating system) for passwords,
passphrases, and PSKs. This commit is only adding the framework part
needed to support this, i.e., no actual configuration parameter can
yet use this new mechanism. In addition, only a simple test backend
is added to allow developer testing of the functionality.

Without this, we can get into a tight loop because the
code in general doesn't add eloop exception handlers,
so socket reporting the POLLERR would never be read.
With this change, any socket with POLLERR or POLLHUP
asserted will be handled by the read logic.

Add the option (-T) to wpa_supplicant to log all debug messages into the
kernel tracing, allowing to aggregate kernel debugging with
wpa_supplicant debugging and recording all with trace-cmd.
Since tracing has relatively low overhead and can be filtered
afterwards, record all messages regardless of log level. However, it
will honor the -K option and not record key material by default.

It looks like some USIM cards respond with 0x67 (Wrong length) instead
of 0x6c to 00 b2 01 04 ff. This was getting rejected in
scard_get_record_len(). ETSI TS 102 221 is not very clear on this
detail, but it looks fine to accept the 0x67 error value, too, to learn
the record length.

The base64 encoded data cannot included pad characters in the middle, so
we can stop the loop at the first sequence of pad characters. If the
sequence includes more than two pad characters, the encoding is invalid
and we can indicate failure.
Commit 19ec1f262e tried to fix some
cases for history prev selection, but it broke others. Fix this
properly by using a separate entry for the current edit line that
is not yet in history buffer.
os_*() wrappers should be used instead of functions from time.h.
Removing the header from includes.h enforces this. os_unix.c can
include this its uses are valid wrapper calls. wps_upnp.c uses
gmtime() for which there is no os_*() wrapper available yet, so
allow it to use time.h, too. Similarly, allow dump_state.c to
use time.h for ctime().
This file is a part of the radiotap parser that Andy Green agreed to
relicense under the BSD license (per email, 11 Aug 2007 07:42:05
+0100). The copyright/license statement was updated in radiotap.c,
but this radiotap_iter.h file was forgotten at that point.
In theory, these calls could fail, but it is not really likely to
happen in practice in the use case here. Anyway, check that they do
not return an error before accepting the length of the file.
CFLAGS += -DCONFIG_VALGRIND can now be used to enable support for
Valgrind client requests to help in removing some non-issues from
Valgrind reports. This is mainly aimed at allowing unknown ioctl
results to be marked as defined data.
If the os_time_t variable used for the expiration time (seconds)
overflows when the registered timeout value is being added,
assume that the event would happen after an infinite time, i.e.,
would not really happen in practice. This fixes issues with
long key timeouts getting converted to immediate expiration due
to the overflow.
This converts number of debugging messages to use wpa_msg() in order
to allow the interface name to be shown with the messages.
A new function, wpa_dbg(), is introduced to allow
CONFIG_NO_STDOUT_DEBUG=y builds to remove the debug strings. This is
otherwise identical with wpa_msg(), but it gets compiled out if stdout
debugging is disabled.
This makes log files much more readable if multiple interfaces
are being controlled by the same process. The interface name is
added to stdout/file/syslog entries, but not to the messages
sent to control interface monitors to avoid issues with parsing
in external programs.

Previously, both NULL and ff:ff:ff:ff:ff:ff addr were used in various
places to indicate default/broadcast keys. Make this more consistent
and useful by defining NULL to mean default key (i.e., used both for
unicast and broadcast) and ff:ff:ff:ff:ff:ff to indicate broadcast
key (i.e., used only with broadcast).
This can be used by external programs (e.g., wlantest_cli) to inject
raw frames (hex dump of the frame header and body). The data can be
requested to be sent as-is or protected with the current key.
The previous commit broke completion in various places. The proper
way of handling the completion of full word is to verify whether
there are more than one possible match at that point.
Completion needs to be done even if the full word has been entered.
In addition, fix the space-after-full-word to properly allocate room
for the extra character when completion is used in the middle of the
string.
This adds new commands for wlantest_cli to request wlantest to
inject frames. This version can only send out Authentication
frames and unprotected SA Query Request frames, but there is
now place to add more frames and encryption with future commits.
This patch adds support for wired IEEE 802.1X client on the Solaris.

The arithmetic on void pointer exists in trace routine. On GNU C, it
works because void pointer size is 1, but not all compilers behave like
this. So this patch specifies the size of the pointer.
Some frequent debug prints are of limited use and make debug output
difficult to read. Make them use a new debug level so that -dd
provides more readable output (-ddd can now be used to enable
the excessive debug prints).
There are no subdirectories in any of these directories or plans
for adding ones. As such, there is no point in running the loop
that does not do anything and can cause problems with some shells.
This version of the MAC address parser allows number of different
string formats for the address (e.g., 00:11:22:33:44:55, 0011.2233.4455,
001122334455, 00-11-22-33-44-55). It returns the number of characters
used from the input string in case of success.
This patch allows wpa_supplicant to compile on Debian's kfreebsd

Better make sure the eloop_timeout data gets fully initialized. The
current code is filling in all the fields, but it is clearer to just
zero the buffer to make sure any new field added to the structure gets
initialized.
This WPA_TRACE=y additions allows components to register active references
to memory that has been provided to them as a pointer. If such an actively
referenced memory area is freed, tracer will report this as an error and
backtraces of both the invalid free and the location where this pointer
was marked referenced are shown.
Use an extra header to move the returned pointer to break os_free()
or free() of the returned value and verify that the correct magic
is present when freeing or resizing the wpabuf. Show backtrace on
invalid wpabuf use.
WPA_TRACE=y builds will now verify that memory allocation in done
consistently using os_{zalloc,malloc,realloc,strdup,free} (i.e., no
mixing of os_* functions and unwrapper functions). In addition, some
common memory allocation issues (double-free, memory leaks, etc.) are
detected automatically.
WPA_TRACE=y can now be used to enable internal backtrace support that
will provide more details about implementation errors, e.g., when some
resources are not released correctly. In addition, this will print out
a backtrace automatically if SIGSEGV is received.
This allows libeap.a and libeap.so to be built by merging in multiple

The following defines are not really needed in most places, so

This is like wpa_msg(), but the output is directed only to
ctrl_interface listeners. In other words, the output will not be
shown on stdout or in syslog.
Change scan result reporting to use wpa_msg_ctrl() for
CTRL-EVENT-SCAN-RESULTS message at info level and wpa_printf() at

gcc 4.4 ends up generating strict-aliasing warnings about some very common
networking socket uses that do not really result in a real problem and
cannot be easily avoided with union-based type-punning due to struct
definitions including another struct in system header files. To avoid having
to fully disable strict-aliasing warnings, provide a mechanism to hide the
typecast from aliasing for now. A cleaner solution will hopefully be found
in the future to handle these cases.
This is a patch for OpenBSD wired IEEE 802.1X. This is only for wired,

If base64_encode() were to be used with a huge data array, the
previous version could have resulted in overwriting the allocated
buffer due to an integer overflow as pointed out in
http://www.freebsd.org/cgi/query-pr.cgi?pr=137484. However, there
are no know use cases in hostapd or wpa_supplicant that would do that.
Anyway, the recommended change looks reasonable and provides additional
protection should the base64_encode() function be used for something
else in the future.
