Hi, I was testing my Huawei E1552 with connman and noticed that ofono crashes if I use incorrect APN name. Under gdb it didn't crash but it busylooped instead and this was in the log: Jul 26 16:46:02 tukki ofonod[14367]: Modem:> AT+CGDCONT=1,"IP","foobar"\r Jul 26 16:46:02 tukki ofonod[14367]: Modem:< \r\nOK\r\n Jul 26 16:46:02 tukki ofonod[14367]: Modem:> AT+CGDATA="PPP",1\r Jul 26 16:46:02 tukki ofonod[14367]: Modem:< \r\nCONNECT\r\n Jul 26 16:46:03 tukki ofonod[14367]: Pcui:< \r\n^RSSI:22\r\n Jul 26 16:46:04 tukki ofonod[14367]: drivers/atmodem/gprs-context.c:ppp_disconnect() Jul 26 16:46:04 tukki ofonod[14367]: plugins/huawei.c:huawei_disconnect() Jul 26 16:46:04 tukki ofonod[14367]: src/gprs.c:gprs_context_remove() atom: 0x6c88a0 Jul 26 16:46:04 tukki ofonod[14367]: drivers/atmodem/gprs-context.c:at_gprs_context_remove() Jul 26 16:46:04 tukki ofonod[14367]: plugins/huawei.c:huawei_disconnect() Jul 26 16:46:04 tukki ofonod[14367]: src/gprs.c:gprs_context_remove() atom: 0x6c88a0 Jul 26 16:46:04 tukki ofonod[14367]: drivers/atmodem/gprs-context.c:at_gprs_context_remove() Jul 26 16:46:04 tukki ofonod[14367]: plugins/huawei.c:huawei_disconnect() Jul 26 16:46:04 tukki ofonod[14367]: src/gprs.c:gprs_context_remove() atom: 0x6c88a0 Jul 26 16:46:04 tukki ofonod[14367]: drivers/atmodem/gprs-context.c:at_gprs_context_remove() Jul 26 16:46:04 tukki ofonod[14367]: plugins/huawei.c:huawei_disconnect() Jul 26 16:46:04 tukki ofonod[14367]: src/gprs.c:gprs_context_remove() atom: 0x6c88a0 Jul 26 16:46:04 tukki ofonod[14367]: drivers/atmodem/gprs-context.c:at_gprs_context_remove() Jul 26 16:46:04 tukki ofonod[14367]: plugins/huawei.c:huawei_disconnect() Jul 26 16:46:04 tukki ofonod[14367]: src/gprs.c:gprs_context_remove() atom: 0x6c88a0 Jul 26 16:46:04 tukki ofonod[14367]: drivers/atmodem/gprs-context.c:at_gprs_context_remove() Jul 26 16:46:04 tukki ofonod[14367]: plugins/huawei.c:huawei_disconnect() Jul 26 16:46:04 tukki ofonod[14367]: src/gprs.c:gprs_context_remove() atom: 0x6c88a0 Jul 26 16:46:04 tukki ofonod[14367]: drivers/atmodem/gprs-context.c:at_gprs_context_remove() Jul 26 16:46:04 tukki ofonod[14367]: plugins/huawei.c:huawei_disconnect() Jul 26 16:46:04 tukki ofonod[14367]: src/gprs.c:gprs_context_remove() atom: 0x6c88a0 Jul 26 16:46:04 tukki ofonod[14367]: drivers/atmodem/gprs-context.c:at_gprs_context_remove() Jul 26 16:46:04 tukki ofonod[14367]: plugins/huawei.c:huawei_disconnect() Jul 26 16:46:04 tukki ofonod[14367]: src/gprs.c:gprs_context_remove() atom: 0x6c88a0 Jul 26 16:46:04 tukki ofonod[14367]: drivers/atmodem/gprs-context.c:at_gprs_context_remove() Jul 26 16:46:04 tukki ofonod[14367]: plugins/huawei.c:huawei_disconnect() Jul 26 16:46:04 tukki ofonod[14367]: src/gprs.c:gprs_context_remove() atom: 0x6c88a0 Jul 26 16:46:04 tukki ofonod[14367]: drivers/atmodem/gprs-context.c:at_gprs_context_remove() Jul 26 16:46:04 tukki ofonod[14367]: plugins/huawei.c:huawei_disconnect() Jul 26 16:46:04 tukki ofonod[14367]: src/gprs.c:gprs_context_remove() atom: 0x6c88a0 Jul 26 16:46:04 tukki ofonod[14367]: drivers/atmodem/gprs-context.c:at_gprs_context_remove() Jul 26 16:46:04 tukki ofonod[14367]: plugins/huawei.c:huawei_disconnect() Jul 26 16:46:04 tukki ofonod[14367]: src/gprs.c:gprs_context_remove() atom: 0x6c88a0 Jul 26 16:46:04 tukki ofonod[14367]: drivers/atmodem/gprs-context.c:at_gprs_context_remove() Jul 26 16:46:04 tukki ofonod[14367]: plugins/huawei.c:huawei_disconnect() Jul 26 16:46:04 tukki ofonod[14367]: src/gprs.c:gprs_context_remove() atom: 0x6c88a0 So huawei_disconnect() is recursively in an endless loop. Any ideas how to fix this properly? -- Kalle Valo
