Sagar Bijwe 665b0b4b3b wpa_supplicant: Fix compilation errors when USE_MBEDTLS is disabled.
This is a regression from earlier commit related to TLSV12 which used
sha functions that are currently declared static.
Solution: Follow upstream code structure and resolve the errors.

Sagar Bijwe 0f1710d878 wpa_supplicant: Fix SAE test-case failure on mbedtls version udpate
Problem:
mbedtls_ctr_drbg_context was initialized in crypto_ec_point_mul. This
was okay in releases before 2.16.4 as entropy_len used to get set to
MBEDTLS_CTR_DRBG_ENTROPY_LEN in function mbedtls_ctr_drbg_seed. The
function is now changed to set the length to
MBEDTLS_CTR_DRBG_ENTROPY_LEN if previous length is 0 and hence the bug.

Solution:
Initialize mbedtls_ctr_drbg_context in crypto_ec_point_mul.

Sagar Bijwe aceb141d2b wpa_supplicant: Adding SAE modules with testcase
This change ports SAE(Simultaneous Authentication of Equals)
feature from wpa_supplicant and makes it work with mbedtls
crypto APIs. Currently only group 19 is supported. A sample
SAE handshake is included in the testcase. Other minor
changes for DH groups are also included.

Sagar Bijwe bd5d086475 wifi: Add PMK caching feature for station WPA2-enterprise
1) Added PMK caching module from wpa_supplicant.
2) Modified wpa_sm to
    a) Add entry to PMK cache when first time associated to an AP.
    b) Maintain entry across the associations.
    c) Clear current PMKSA when deauth happens.
    d) Search for an entry when re-associating to the same AP and
       set it as current PMKSA
    e) Wait for msg 1/4 from AP instead of starting EAP authentication.
    f) Check PMKID in msg 1 with current PMKSA/cache.
    g) Use the cached PMK to complete 4-way handshake.
3) Remove config_bss callback as it was redundant and used to cause
   problems for PMK caching flow.

Sagar Bijwe b1f657fc65 wifi: Avoid recalculating PMK when esp_wifi_set_config is not called
Scenarios where this fix is applicable.
1) Every time the system is powered-on/restarted without calling
   esp_wifi_set_config.
2) esp_wifi_init()/connect()/stop()/deinit() is called multiple
   times without esp_wifi_set_config.

Sagar Bijwe d32128440d nvs_flash: Detect key partition as uninitialised even if encrypted by bootloader
Currently, only erase operation performed by the application leads
to detection of NVS key partition as uninitialised. This change
adds additional checks for detecting partition as uninitialised,
when device boots first time right after encryption by bootloader.

Sagar Bijwe 05220d9cda CMake: Make IDF_PATH available to Kconfiglib when not explicitly set.
When IDF_PATH is not set by the user, cmake infers the same through
other means and sets it as an environment variable. However, some
sub-invocation of cmake may not see this variable as it is not set
in the parent. This change adds a custom command for exporting IDF_PATH
just before invoking ldgen so that IDF_PATH can be used in Kconfig
without any errors.

Sagar Bijwe fc37dc1944 nvs_flash: Fix compilation of host testcases when g++-8.x is used.
When std::bind is used, it requires inclusion of <functional> header.
This was not mandatory with earlier versions of g++ (4.x), may be because they
had experimental support for c++11.

Sagar Bijwe 911f96ad21 nvs_flash: Fix nvs_set_blob hang when partition is near to FULL
Marking a page full does not skip it from page selection process and the
same page might get returned if there is no other page with more unused
entries. Added a check for the same while storing blobs.

Sagar Bijwe 1df85e0039 nvs_flash: Version compatibility check for nvs storage
This change adds a check for compatibility between the nvs version
found on nvs flash and the one assumed by running code during nvs
initialization. Any mismatch is reported to the user using new error
code ESP_ERR_NVS_NEW_VERSION_FOUND.

Sagar Bijwe 5a27a63541 nvs-flash: Support for blobs larger than half of SPI Flash sector size
This change removes the earlier limitation of 1984 bytes for storing data-blobs.
Blobs larger than the sector size are split and stored on multiple sectors.
For this purpose, two new datatypes (multi-page index and multi-page data) are
added for entries stored in the sectors. The underlying read, write, erase and find
operations are modified to support these large blobs. The change is transparent
to users of the library and no special APIs need to be used to store these large
blobs.

Sagar Bijwe fd7b794e81 FATFS support without wear levelling
This change allows readonly FATFS to be mounted without wear levelling
support. This will provide the customers a simple way to mount FATFS images
generated on host and flashed onto the chip during factory provisioning.
Since NVS encryption is not supported yet and NVS entry size is limited,
the change will provide an easy alternative for securing the provisioning data
by just marking FATFS parition as encrypted.

Sagar Bijwe 7ae1df1c5e nvs: Fix recovery from power-off while page is being freed
Currently when page is being freed, items are individually moved from
FREEING page to ACTIVE page and erased. If power-off happens during the
process, the remaining entries are moved to ACTIVE page during recovery.
The problem with this approach is there may not be enough space on
ACTIVE page for all items if an item was partially written before
power-off and erased during recovery. This change moves all the items
from FREEING to ACTIVE page and then erased the FREEING page, If
power-off happens during the process, then ACTIVE page is erased and the
process is restarted.

Sagar Bijwe 21584827b3 dhcp/dhcpserver Fix max station limit check in dhcp server
Currently when MAX_STATION limit in DHCP config is set to N, dhcp server
issues only N-1 IP addresses. This is problematic from customer
perspective if both SoftAP MAX_STATION and DHCP MAX_STATION limit is set
to same value. With this change DHCP server can issue N addresses that
is inline with the set limit.

Sagar Bijwe 9a3c4b7134 nvs: Fix recovery after power-off during erase operation
Current code for recovery after power-off do not clean-up partially
erased items for FULL pages. If the erasure was part of modification
operation, this gets luckily cleaned-up because of duplicate detection
logic. For erase-only operation, the problem still exists. This patch
adds the recovery for FULL pages also.

Sagar Bijwe 7e79471ece nvs: Fix page selection algo to consider free entry counts as well
Current page selection algorithm selects a page for compaction based on just erased counts
and gives up when it does not find any page with erased count greater than 0. This is
problematic since the current allocation procedure skips the active page if there is not
enough room for the item in that page leaving free chunks on the pages. This change modifies
the algorithm to consider both erased as well as free counts on the candidate pages.
