58b2759551 trace: Only permit explicit prefix matching for functions
The matching code currently only tests whether the prefix of a function
matches. Make this more strict by ensuring that the function name is not
longer.

However, as this breaks some tests (due to inlining), add the ability to
do an explicit prefix match by appending a '*' to the function name. Use
this to change the eap_eke_prf match to eap_eke_prf_* in order to match
one of the actual implementations.

49344db095 trace: Use strncmp() to match function names
The functions specified by the user might be longer than the function in
the backtrace, potentially overflowing the memcmp(). In practice, it
should not be a relevant out-of-memory read. However, we can use
strncmp() instead.

Note that, as before, this is only a prefix match. If a function name is
longer in the backtrace it will still match.

Hostapd uses 'crc32' name for IEEE802.11 CRC-32 routine. This name is
too generic. Buildroot autobuilder detected build configuration that
failed to build due to the naming conflict: static linking with openssl
using zlib-ng as a zlib provider, e.g. see:
- http://autobuild.buildroot.net/results/9901df820d3afa4cde78e8ad6d62cb8ce7e69fdb/
- http://autobuild.buildroot.net/results/ac19975f0bf77f4a8ca574c374092ba81cd5a332/

faf9c04cb5 Remove a host of unnecessary OPENSSL_IS_BORINGSSL ifdefs
The <openssl/buf.h> include is relevant in both OpenSSL and BoringSSL
because the file uses BUF_MEM (include what you use). OpenSSL just
happened to include it via another file. OpenSSL also spells it
<openssl/buffer.h>, not matching the type, so use the compatible
spelling.

Additionally all the CHECKED_CAST and manual STACK_OF(T) definitions
call into BoringSSL internals. The correct, public APIs are simply to
just use the same code as OpenSSL and call the DEFINE_STACK_OF macros.

10502ad59f radiotap: Fix compiler issues with packed structures
Replace the Radiotap parser platform.h file with use of helper functions
from utils/common.h to avoid compiler issues with the updated design and
getting pointers to members of packet structs.

Silence the warning about _next_bitmap assignment. This pointer is
dereferenced only with operations that are safe for unaligned access, so
the compiler warning is not helpful here.

__packed might not be defined in this context, so use STRUCT_PACKED from
utils/common.h.

e680a51e94 ext_password: Implement new file-based backend
It was not easily possible to separate configuration of an interface and
credentials when using the configuration file instead of the control
interface or D-Bus interface for setting up the network profiles. This
makes it hard to distribute configuration across a set of nodes which
use wpa_supplicant without also having to store credentials in the same
file. While this can be solved via scripting, having a native way to
achieve this would be preferable.

Turns out there already is a framework to have external password
storages. It only had a single "test" backend though, which is kind of
an in-memory store which gets initialized with all passwords up front
and is mainly for testing purposes. This isn't really suitable for the
above use case: the backend cannot be initialized as part of the central
configuration given that it needs the credentials, and we want to avoid
scripting.

This commit thus extends the infrastructure to implement a new backend,
which instead uses a simple configuration file containing key-value
pairs. The file follows the format which wpa_supplicant.conf(5) uses:
empty lines and comments are ignored, while passwords can be specified
with simple `password-name=password-value` assignments.

With this new backend, splitting up credentials and configuration
becomes trivial:

    # /etc/wpa_supplicant/wpa_supplicant.conf
    ext_password_backend=file:/etc/wpa_supplicant/psk.conf

    network={
        ssid="foobar"
        psk=ext:foobar
    }

    # /etc/wpa_supplicant/psk.conf
    foobar=ecdabff9c80632ec6fcffc4a8875e95d45cf93376d3b99da6881298853dc686b

Alternative approaches would be to support including other configuration
files in the main configuration, such that common configuration and
network declarations including credentials are split up into separate
files. But the implementation would probably have been more complex
compared to reusing the already-existing framework for external password
backends.

e9f449ba59 wpa_supplicant: Move wpa_config_get_line() into utils
The function wpa_config_get_line() is used by the wpa_supplicant config
file parser to retrieve the next non-comment non-blank line. We'll need
the same kind of functionality to implement the file-based external
password backend, so as a preparatory step this commit extracts the
function into its own standalone file in the utils package.

No functional changes are expected from this commit.

bba926350a Fix gcc-10 build with -Werror=array-bounds and dl_list_for_each()
The earlier workaround for UBSAN issues in commit 3b6b3ae581 ("Modify
dl_list_for_each() to not use unaligned access with WPA_TRACE") ended up
using a construction in which the type cast to the containing structure
was compared instead of the struct dl_list pointers. While that worked
around the UBSAN issue, it resulted in a comparison that gcc-10
interprets as being out of bounds for struct dl_list (which it obviously
is since this is to find the start of the containing structure).

Revert that workaround and instead, mark the struct dl_list used within
struct os_alloc_trace to have matching 16 octet alignment as the
containing structure. This is also restoring consistent design for
dl_list_for_each*().

87098d3324 build: Put archive files into build/ folder too
This is something I hadn't previously done, but there are
cases where it's needed, e.g., building 'wlantest' and then
one of the tests/fuzzing/*/ projects, they use a different
configuration (fuzzing vs. not fuzzing).

Perhaps more importantly, this gets rid of the last thing
that was dumped into the source directories, apart from
the binaries themselves.

Note that due to the use of thin archives, this required

722138cd25 build: Put object files into build/ folder

files into the build/ folder at the root, and put each

This then allows us to build hostapd and wpa_supplicant

For the tests keep the objects in place for now (and to
do that, add the build rule) so that we don't have to
rewrite all of that with $(call BUILDOBJS,...) which is
just noise there.
