This function is meant for comparing passwords or hash values where
difference in execution time could provide external observer information
about the location of the difference in the memory buffers. The return
value does not behave like os_memcmp(), i.e., os_memcmp_const() cannot
be used to sort items into a defined order. Unlike os_memcmp(),
execution time of os_memcmp_const() does not depend on the contents of
the compared memory buffers, but only on the total compared length.

Relative time shouldn't be calculated based on gettimeofday
because that clock can jump (e.g., when the time is adjusted
by the system administrator.)
On systems where that is available, use CLOCK_BOOTTIME (on
fairly recent Linux systems, this clock takes into account
the time spend suspended) or CLOCK_MONOTONIC (on Linux and
some POSIX systems, this clock is just freely running with
no adjustments.)

ANDROID_SETGROUPS_OVERRIDE macro can now be used to override setgroups()
values based on build configuration.

trace.h may end up including system header files that define offsetof,
so include the compatibility definition from list.h only after this.

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().
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.
This patch adds support for wired IEEE 802.1X client on the Solaris.
I have tested with these:
OS : OpenSolaris 2009.06
EAP : EAP-MD5
Switch : Cisco Catalyst 2950
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.
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.
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.
This is a patch for OpenBSD wired IEEE 802.1X. This is only for wired,
not wireless, because OpenBSD uses wpa_supplicant only on wired now.
