Patch Set 7: Code-Review+1

it would be nice to have the MNCC protocol version change in a separate patch, so that it is easy to read what parts relate to the bare protocol change, and what parts relate to functional change in osmo-msc

i generally dislike reverse logic booleans, the double negation can make reading logic a nightmare...

  disabled = (foo() != 0);

it's better to choose the boolean name as an affirmative, so that "true" does not mean "off".

so here i'd indeed go for "lcls_permitted"


https://gerrit.osmocom.org/c/osmo-msc/+/24236/7/include/osmocom/msc/mncc.h 
File include/osmocom/msc/mncc.h:

PS7, Line 164: 	struct osmo_gcr_parsed gcr;

this is a good place, besides the SDP always being in the end, this leaves previous version MNCC unchanged.

PS7, Line 511:       "no lcls-disable",
also here i would much perfer 'lcls-permitted' to avoid double negation
