Hello Richard, thank you, really helpful. Regarding the cdp module, we could provide some access to a test setup. A colleague will contact you about that.

On platforms with OpenSSL 1.1.1 — shared memory contention is much harder to trigger — but this setting is recommended when other modules that use TLS are loaded" =============================== Deployment note (for the wiki?) Here is an SRE/deployment note — not sure of a good place to put this (maybe the wiki) "To validate the config for OpenSSL 3/1.1.1 memory contention potential run the main kamailio process under gdb (don't follow child forks: "set follow-fork-mode parent" — the default setting anyway) # ** EITHER ** # deb-based: install dbgsym for libssl3 / libssl1.1 # RPM-based: install debuginfo for openssl, openssl-libs # ** OR ** # configure gdb to use debuginfod for debug symbols # STEP 1 # stop at main(), this step is required because the next breakpoint requires knowledge # of thread#1 gdb> break main gdb> run # STEP 2 # this breakpoint detects if OpenSSL 3 initializes the thread-local err_thread_local # in process#0.thread#1 — this causes shared memory contention gdb> breakpoint CRYPTO_THREAD_set_local thread 1 if $_caller_is("ossl_err_get_state_int", 32) gdb> commands backtrace 32 continue end ##For OpenSSL 1.1.1 gdb> breakpoint CRYPTO_THREAD_set_local thread 1 if $_caller_is("ERR_get_state", 32) gdb> commands backtrace 32 continue end # continue execution of Kamailio gdb> continue If this breakpoint is triggered then the configuration has potential for shared memory contention. Do file an issue at GH with your configuration and the gdb output. " Dev note: I have completed an "audit" of all in-tree modules that load libssl — libcurl, libmariadb, libcrypto, libpq etc. The only one not touched is DIAMETER cdp.so with TLS. If anyone uses this and can provide me with temporary access that would be great.

I haven't seen much activity around issues in the new features/modules. If time allows to build the pages for what-is-new and how-to-upgrade (which I think it should be rather minimal), then I think it should be no other major task. Overall it will be almost two weeks since the 5.8 branch was created.
