[PATCH] libosmocore[master]: osmo-auc-gen: Print hex values without intermittent spaces
by Harald Welte 01 Jun '16

01 Jun '16

Review at https://gerrit.osmocom.org/164 osmo-auc-gen: Print hex values without intermittent spaces When generating some authentication vectors using the osmo-auc-gen utility, it used to print values like this: AUTN: f7 55 bc 47 de d0 00 00 f9 ed 4b 3f 6c 2a 97 6f which is quite difficult to copy+paste on the terminal. Now it generates the following format: Change-Id: I2805615e0c2087ca632e0658b37a9e06929620b6 AUTN: f755bc47ded00000f9ed4b3f6c2a976f --- M utils/osmo-auc-gen.c 1 file changed, 7 insertions(+), 7 deletions(-) git pull ssh://gerrit.osmocom.org:29418/libosmocore refs/changes/64/164/1 diff --git a/utils/osmo-auc-gen.c b/utils/osmo-auc-gen.c index b026e28..3b3e557 100644 --- a/utils/osmo-auc-gen.c +++ b/utils/osmo-auc-gen.c @@ -48,18 +48,18 @@ static void dump_auth_vec(struct osmo_auth_vector *vec) { - printf("RAND:\t%s\n", osmo_hexdump(vec->rand, sizeof(vec->rand))); + printf("RAND:\t%s\n", osmo_hexdump_nospc(vec->rand, sizeof(vec->rand))); if (vec->auth_types & OSMO_AUTH_TYPE_UMTS) { - printf("AUTN:\t%s\n", osmo_hexdump(vec->autn, sizeof(vec->autn))); - printf("IK:\t%s\n", osmo_hexdump(vec->ik, sizeof(vec->ik))); - printf("CK:\t%s\n", osmo_hexdump(vec->ck, sizeof(vec->ck))); - printf("RES:\t%s\n", osmo_hexdump(vec->res, vec->res_len)); + printf("AUTN:\t%s\n", osmo_hexdump_nospc(vec->autn, sizeof(vec->autn))); + printf("IK:\t%s\n", osmo_hexdump_nospc(vec->ik, sizeof(vec->ik))); + printf("CK:\t%s\n", osmo_hexdump_nospc(vec->ck, sizeof(vec->ck))); + printf("RES:\t%s\n", osmo_hexdump_nospc(vec->res, vec->res_len)); } if (vec->auth_types & OSMO_AUTH_TYPE_GSM) { - printf("SRES:\t%s\n", osmo_hexdump(vec->sres, sizeof(vec->sres))); - printf("Kc:\t%s\n", osmo_hexdump(vec->kc, sizeof(vec->kc))); + printf("SRES:\t%s\n", osmo_hexdump_nospc(vec->sres, sizeof(vec->sres))); + printf("Kc:\t%s\n", osmo_hexdump_nospc(vec->kc, sizeof(vec->kc))); } } -- To view, visit https://gerrit.osmocom.org/164 To unsubscribe, visit https://gerrit.osmocom.org/settings Gerrit-MessageType: newchange Gerrit-Change-Id: I2805615e0c2087ca632e0658b37a9e06929620b6 Gerrit-PatchSet: 1 Gerrit-Project: libosmocore Gerrit-Branch: master Gerrit-Owner: Harald Welte <laforge(a)gnumonks.org>

Gerrit and Jenkins: merge conflict vs. +1 Verified

Then how on earth can Jenkins add a +1 for a successful build to it?? Something about these gerrit merge conflicts is completely wrong. I'd appreciate if we could clarify this. Any ideas on how to find out? ~Neels
