...or at least have a px5g-wolfssl variant as well (that shouldn't be
too hard to do)
I've followed closely on how wolfSSL support was added to hostap.git
and even though wolfSSL's API is largely identical to OpenSSL's API, it
still took a large number of commits and almost two years (!) until
things are now working with wolfSSL as well as they do with OpenSSL.
Of course it'd be great to have wpad-mbedtls but I'm afraid it's far
from being doable for the 2020 relrease.
My original motivation to port the wolfSSL variants of hostapd was to
get 802.11s with SAE working on 4/32 devices which also run a routing
protocol (batman-adv) at the same time and still be able to generate
firmware for those devices using the released ImageBuilder.
For 19.07.4 this will finally be reality.
Regarding the 2020 release:
While I agree that release sysupgrade/factory images should have a
similar featureset (and hence should all come with wpad-basic-wolfssl,
libustream-wolfssl and tbd px5g-wolfssl installed), it'd be nice to
still offer ImageBuilder functional to generate images for 4/32 devices
without having to build everything from source.
Hence it makes sense exclude device images which are anyway not going
to be offered for download (ie. 4/32 devices) from this change and keep
them with wpad-mini. In the end it doesn't matter too much as anyone
using the IB for those devices is anyway likely to modify the default
package selection in order to make things fit into 4MB.
