From f17b06901049e54dbfa8b01c278cdc2e3ae5d62d Mon Sep 17 00:00:00 2001 From: Martin Simmons Date: Wed, 5 Nov 2014 14:47:39 +0000 Subject: [PATCH] gdbstub: Add a missing case of signal number translation in gdbstub While using qemu with gdb "target remote" to debug an application that uses fork and exec, the qemu process receives SIGSTOP every time the forked process terminates (sending SIGCHLD). This is caused by a missing call to gdb_signal_to_target in gdbstub.c, which is fixed by this patch: Signed-off-by: Martin Simmons Reviewed-by: Peter Maydell Signed-off-by: Michael Tokarev --- gdbstub.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/gdbstub.c b/gdbstub.c index d1b5afd..0faca56 100644 --- a/gdbstub.c +++ b/gdbstub.c @@ -823,7 +823,10 @@ static int gdb_handle_packet(GDBState *s, const char *line_buf) action = *p++; signal = 0; if (action == 'C' || action == 'S') { - signal = strtoul(p, (char **)&p, 16); + signal = gdb_signal_to_target(strtoul(p, (char **)&p, 16)); + if (signal == -1) { + signal = 0; + } } else if (action != 'c' && action != 's') { res = 0; break; -- 2.7.4
