Switch from wolfssl to mbedtls as default

OpenWrt switched the default cryptographic library from wolfssl to mbedtls. This library is used for HTTPS/TLS in the Webserver providing LuCI and for the cryptographic operations in hostapd. mbedtls provides security updates in their LTS branch without changing the application binary interface (ABI) of the library. wolfssl provides a stable ABI only for a very limited subset of functions. mbedtls allows us to update only mbedtls without the need to recompile and upgrade all users of mbedtls.

Core components update

Core components have the following versions in 23.05.0-rc2:

  • Updated toolchain:
    • musl libc 1.2.4
    • glibc 2.37
    • gcc 12.3.0
    • binutils 2.40
  • Updated Linux kernel
    • 5.15.118 for all targets
  • Network:
    • hostapd master snapshot from March 2023
    • dnsmasq 2.89
    • dropbear 2022.82
  • cfg80211/mac80211 from kernel 6.1.24
  • System userland:
    • busybox 1.36.1

Installed on my WRT32X with lots of packages added.

Excellent SQM on my 300/20Mbit cable with +0/+0 results, USB3 drive and Samba 4.18 hitting 120 MB/s maxing out gigabit LAN, simple-adblock on etc. The bridge offload hack removal seems to be working from my testing too. This is a great build for me so far, thanks devs.


Are the following service releases update mt76 drivers, usually? If not I would hope we get the latest driver in the release.

try build for my ax6 show issue
what that i miss?

That exact error (customizing installed packages) also happened early on with rc1. In that instance, it took about 4 days after the official announcement for package customization to start working. That was a day after I tagged @aparcar (who manages the configuration of in a forum comment about it. I don't know if my post had anything to do with it getting fixed or if it was just a coincidence of timing.


I guess the support of some 8/64 devices which were dropped in rc1 will not be restored? In that case i'm very disappointed in you.

It would be much easier, if you'd give examples about devices that were present in -rc1 and now are no longer in -rc2.

Still no solution for lantiq xrx200 gswip issues ? Does single port device or using single port for modem operations is considered safe?

finally i build own the firmware,
hope no issue.

Netgear WAX202: the WDS client setup is still non-functional on 5 GHz. The client associates, but no traffic flows between the client and br-lan. No such problem on 2.4 GHz.


EDIT: Is the 6 Mbit/s TX rate a coincidence?

The same information from 22.03.5:

Runs perfect on my RT3200 access points. On my Banana R3:

I assume this is as expected?

Would have been nice to see the below pull request accepted… Fingers crossed for RC3… Until then, custom build :sweat_smile:


Running fine on Redmi AX6S with Raspberry Pi 4 server. Thank you

Installed on my two Netgear R7800. Speed improved from RC1 (200/200) to RC2 (330/170). Still worse than 22.03.5 (450/450) (all speeds in Mb/s)


Is that with Ethernet or WiFi?

Upgraded WRT1900ACS and WAC104 from rc1. No issues so far! Seems to be the best build for my WRT1900ACS since the 21 series.


wifi. I have 500/500 fiber to my home. I also forgot to mention that the R7800's are configured as dumb accesspoints. The nat'ing + routing is handled by a PC (Intel NUC7i5BNH) running Ubuntu 23.04.

As OpenWrt grows, support for smaller devices becomes unfeasible. Once a device is dropped, it's quite unlike to be supported later.


The thing is not in putting effort into active support of the old devices, but in not putting effort to drop existing support and just keeping automatic builds for them while they work just fine.
