This is a bug in QtWebEngine.
The file
src/3rdparty/chromium/net/third_party/nss/patches/chacha20poly1305.patch
contains the following:
+/* This is a bodge to allow this code to be compiled against older NSS
+ * headers. */
+#ifndef CKM_NSS_CHACHA20_POLY1305
+#define CKM_NSS_CHACHA20_POLY1305 (CKM_NSS + 26)
Unfortunately, CKM_NSS + 26 got used for something else in nss 3.21:
#define CKM_NSS_TLS_EXTENDED_MASTER_KEY_DERIVE_DH (CKM_NSS + 26)
In nss 3.23, we now have:
#define CKM_NSS_CHACHA20_POLY1305 (CKM_NSS + 28)
This means QtWebEngine isn't using the right value.
To fix this, QtWebEngine needs to be patched to use the proper value of CKM_NSS
+ 28 in the following files:
src/3rdparty/chromium/net/socket/ssl_client_socket_nss.cc
src/3rdparty/chromium/net/third_party/nss/patches/chacha20poly1305.patch
src/3rdparty/chromium/net/third_party/nss/ssl/ssl3con.c
src/3rdparty/chromium/third_party/nss/patches/nss-chacha20-poly1305.patch
src/3rdparty/chromium/third_party/nss/nss/lib/util/pkcs11n.h
Once that is done and QtWebEngine is rebuilt, I believe it will be compatible
with nss 3.21 and 3.23.
I am closing this bug since the product using QtWebEngine is not in
Ubuntu and there is no further action to be done.
