Vadim Yanitskiy vyanitskiy at sysmocom.deHi all, we seem to have problems with structure alignment in the new version of the PCUIF protocol: PCUIFv9: sizeof(struct gsm_pcu_if) -> 212; 212 % 4 == 0 PCUIFv10: sizeof(struct gsm_pcu_if) -> 1006; 1006 % 4 != 0 I think we would need to add/remove some padding. The question is whether we should make sure that all structures are aligned, or having the top level struct gsm_pcu_if aligned would be enough? Even in PCUIFv9 not all structures are properly aligned: sizeof(struct gsm_pcu_if_data_cnf_dt) -> 21; 21 % 4 -> 1, sizeof(struct gsm_pcu_if_rts_req) -> 13; 13 % 4 -> 1, sizeof(struct gsm_pcu_if_rach_ind) -> 15; 15 % 4 -> 3, sizeof(struct gsm_pcu_if_pag_req) -> 11; 11 % 4 -> 3, sizeof(struct gsm_pcu_if_susp_req) -> 11; 11 % 4 -> 3. I devise by 4 because the widest member is uint32_t in all cases. Kind regards, Vadim. -- - Vadim Yanitskiy <vyanitskiy at sysmocom.de> http://www.sysmocom.de/ ======================================================================= * sysmocom - systems for mobile communications GmbH * Alt-Moabit 93 * 10559 Berlin, Germany * Sitz / Registered office: Berlin, HRB 134158 B * Geschaeftsfuehrer / Managing Director: Harald Welte
