Pau Espin Pedrol gerrit-no-reply at lists.osmocom.orgHello Harald Welte, Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/10443 to look at the new patch set (#2). Change subject: sscp_scrc: Fix memleak of xua_msg when handing it to scrc_rx_mtp_xfer_ind_xua ...................................................................... sscp_scrc: Fix memleak of xua_msg when handing it to scrc_rx_mtp_xfer_ind_xua Fixes following error provided by LeakSanitizer: Indirect leak of 1496 byte(s) in 11 object(s) allocated from: #0 0x7f1eb3332d99 in __interceptor_malloc /build/gcc/src/gcc/libsanitizer/asan/asan_malloc_linux.cc:86 #1 0x7f1eae617b61 in _talloc_zero (/usr/lib/libtalloc.so.2+0x5b61) #2 0x7f1eb063e365 in xua_msg_alloc /home/pespin/dev/sysmocom/git/libosmo-sccp/src/xua_msg.c:49 #3 0x7f1eb0650ee3 in osmo_sccp_to_xua /home/pespin/dev/sysmocom/git/libosmo-sccp/src/sccp2sua.c:1298 #4 0x7f1eb0668d6a in mtp_user_prim_cb /home/pespin/dev/sysmocom/git/libosmo-sccp/src/sccp_user.c:173 #5 0x7f1eb068ba86 in deliver_to_mtp_user /home/pespin/dev/sysmocom/git/libosmo-sccp/src/osmo_ss7_hmrt.c:94 #6 0x7f1eb068bf00 in hmdt_message_for_distribution /home/pespin/dev/sysmocom/git/libosmo-sccp/src/osmo_ss7_hmrt.c:133 #7 0x7f1eb068d345 in m3ua_hmdc_rx_from_l2 /home/pespin/dev/sysmocom/git/libosmo-sccp/src/osmo_ss7_hmrt.c:275 #8 0x7f1eb063c08f in m3ua_rx_xfer /home/pespin/dev/sysmocom/git/libosmo-sccp/src/m3ua.c:586 #9 0x7f1eb063cea6 in m3ua_rx_msg /home/pespin/dev/sysmocom/git/libosmo-sccp/src/m3ua.c:739 #10 0x7f1eb0687188 in xua_cli_read_cb /home/pespin/dev/sysmocom/git/libosmo-sccp/src/osmo_ss7.c:1590 #11 0x7f1eaff77db4 in osmo_stream_cli_read /home/pespin/dev/sysmocom/git/libosmo-netif/src/stream.c:192 #12 0x7f1eaff79091 in osmo_stream_cli_fd_cb /home/pespin/dev/sysmocom/git/libosmo-netif/src/stream.c:276 #13 0x7f1eaf259795 in osmo_fd_disp_fds /home/pespin/dev/sysmocom/git/libosmocore/src/select.c:217 #14 0x7f1eaf259abb in osmo_select_main /home/pespin/dev/sysmocom/git/libosmocore/src/select.c:257 #15 0x55666c1bebd3 in main /home/pespin/dev/sysmocom/git/osmo-msc/src/osmo-msc/msc_main.c:697 #16 0x7f1ead1c306a in __libc_start_main (/usr/lib/libc.so.6+0x2306a) #17 0x55666c1bc649 in _start (/home/pespin/dev/sysmocom/build/new/out/bin/osmo-msc+0x185649) The code path is the following, starting from mpt_user_prim_cb: mtp_user_prim_cb osmo_sccp_to_xua xua_msg_alloc scrc_rx_mtp_xfer_ind_xua sccp_scoc_rx_from_scrc scrc_node_6 scrc_node_4 scrc_translate_node_9 So the xua_msg is created in mtp_user_prim_cb through osmo_sccp_to_xua and then handed over to scrc_rx_mtp_xfer_ind_xua which transfers the xua_msg and thus should take ownserhip of it, and consecuently freeing it once it's done using it.
