[M] Change in libosmo-sccp[master]: SCCP: implement variable limit on Optional Data (CR,CC,CREF,RLSD)

by neels

Attention is currently required from: neels. Hello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libosmo-sccp/+/32361 to look at the new patch set (#2). Change subject: SCCP: implement variable limit on Optional Data (CR,CC,CREF,RLSD) ...................................................................... SCCP: implement variable limit on Optional Data (CR,CC,CREF,RLSD) When the Optional Data surpasses 130 bytes, it is not sent as part of SCCP CR, CC, CREF or RLSD messages, but gets sent separately in a Data Form 1. Make this 130 user configurable. This is specified to be 130 bytes exactly, but to interop with non-conforming peers, make this limit adjustable per cs7 instance, via osmo_sccp_vty_init(). Add and test new VTY config: cs7 instance N sccp max-optional-data (<0-999999>|standard) Related: ITU-T Q.713 4.2 to 4.5 Related: Ia68dad973ef18513b52f5accb5264c557c7295ea osmo-ttcn3-hacks Related: SYS#6423 Change-Id: If35697234796af8943691b2de62218e7dc93a08c --- M src/sccp_internal.h M src/sccp_scoc.c M src/sccp_user.c M src/sccp_vty.c M tests/vty/ss7_asp_test.vty 5 files changed, 112 insertions(+), 3 deletions(-) git pull ssh://gerrit.osmocom.org:29418/libosmo-sccp refs/changes/61/32361/2 -- To view, visit https://gerrit.osmocom.org/c/libosmo-sccp/+/32361 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: libosmo-sccp Gerrit-Branch: master Gerrit-Change-Id: If35697234796af8943691b2de62218e7dc93a08c Gerrit-Change-Number: 32361 Gerrit-PatchSet: 2 Gerrit-Owner: neels <nhofmeyr(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Attention: neels <nhofmeyr(a)sysmocom.de> Gerrit-MessageType: newpatchset
