Fixes the following use after free: ==646625==ERROR: AddressSanitizer: heap-use-after-free on address 0x61200017cab8 at pc 0x0000004f8f29 bp 0x7ffdf465ad30 sp 0x7ffdf465ad20 WRITE of size 8 at 0x61200017cab8 thread T0 #0 0x4f8f28 in wl_list_remove ../common/list.c:181 #1 0x43dd24 in handle_destroy ../sway/desktop/output.c:790 (`wl_list_remove(&output->damage_destroy.link);` here, 214e3030e1dce master branch) #2 0x7f0e573a1c93 in wlr_signal_emit_safe ../util/signal.c:29 #3 0x7f0e57390954 in wlr_output_destroy ../types/wlr_output.c:365 #4 0x7f0e5735e37f in backend_destroy ../backend/x11/backend.c:128 #5 0x7f0e57348147 in wlr_backend_destroy ../backend/backend.c:47 #6 0x7f0e57356f75 in multi_backend_destroy ../backend/multi/backend.c:54 #7 0x7f0e5735710e in handle_display_destroy ../backend/multi/backend.c:107 #8 0x7f0e573f23e4 in wl_display_destroy (/lib64/libwayland-server.so.0+0x93e4) #9 0x42f0b2 in server_fini ../sway/server.c:177 #10 0x42dd01 in main ../sway/main.c:414 #11 0x7f0e570f7041 in __libc_start_main (/lib64/libc.so.6+0x27041) #12 0x40e3bd in _start (/opt/wayland/bin/sway+0x40e3bd) 0x61200017cab8 is located 120 bytes inside of 320-byte region [0x61200017ca40,0x61200017cb80) freed by thread T0 here: #0 0x7f0e57aa9357 in __interceptor_free (/lib64/libasan.so.6+0xb0357) #1 0x7f0e5738b877 in wlr_output_damage_destroy ../types/wlr_output_damage.c:143 #2 0x7f0e5738b2b9 in output_handle_destroy ../types/wlr_output_damage.c:13 #3 0x7f0e573a1c93 in wlr_signal_emit_safe ../util/signal.c:29 #4 0x7f0e57390954 in wlr_output_destroy ../types/wlr_output.c:365 #5 0x7f0e5735e37f in backend_destroy ../backend/x11/backend.c:128 #6 0x7f0e57348147 in wlr_backend_destroy ../backend/backend.c:47 #7 0x7f0e57356f75 in multi_backend_destroy ../backend/multi/backend.c:54 #8 0x7f0e5735710e in handle_display_destroy ../backend/multi/backend.c:107 #9 0x7f0e573f23e4 in wl_display_destroy (/lib64/libwayland-server.so.0+0x93e4) previously allocated by thread T0 here: #0 0x7f0e57aa9887 in __interceptor_calloc (/lib64/libasan.so.6+0xb0887) #1 0x7f0e5738b532 in wlr_output_damage_create ../types/wlr_output_damage.c:91 #2 0x43e4a7 in handle_new_output ../sway/desktop/output.c:875 #3 0x7f0e573a1c93 in wlr_signal_emit_safe ../util/signal.c:29 #4 0x7f0e57357261 in new_output_reemit ../backend/multi/backend.c:143 #5 0x7f0e573a1c93 in wlr_signal_emit_safe ../util/signal.c:29 #6 0x7f0e5736030a in wlr_x11_output_create ../backend/x11/output.c:253 #7 0x7f0e5735e309 in backend_start ../backend/x11/backend.c:113 #8 0x7f0e573480fb in wlr_backend_start ../backend/backend.c:36 #9 0x7f0e57356e61 in multi_backend_start ../backend/multi/backend.c:31 #10 0x7f0e573480fb in wlr_backend_start ../backend/backend.c:36 #11 0x42f4ba in server_start ../sway/server.c:205 #12 0x42dbd7 in main ../sway/main.c:394 #13 0x7f0e570f7041 in __libc_start_main (/lib64/libc.so.6+0x27041) Fixes #5158 |
