From a3bea49c6960a468ee28b6d8dd0664c1ebcbcd02 Mon Sep 17 00:00:00 2001 Message-Id: From: Peter Krempa Date: Tue, 4 Feb 2020 15:07:46 +0100 Subject: [PATCH] qemu: monitor: Improve error message when QEMU reply is too large MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Don't use ERANGE as it doesn't make much sense in the error message. Also point out that the reply from qemu was too large which is not obvious from the original error: error: No complete monitor response found in 10485760 bytes: Numerical result out of range The new message will read: error: internal error: QEMU monitor reply exceeds buffer size (10485760 bytes) Signed-off-by: Peter Krempa Reviewed-by: Jiri Denemark (cherry picked from commit 29d43bf96a3e5886f1b32c78bbb16d1507bd0d9e) https://bugzilla.redhat.com/show_bug.cgi?id=1524278 Message-Id: <0e03a38f096e556cb82eecdb72e7dd5f86eec752.1580824112.git.pkrempa@redhat.com> Reviewed-by: Ján Tomko --- src/qemu/qemu_monitor.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/src/qemu/qemu_monitor.c b/src/qemu/qemu_monitor.c index 4f547bf5ec..0e67851690 100644 --- a/src/qemu/qemu_monitor.c +++ b/src/qemu/qemu_monitor.c @@ -485,9 +485,9 @@ qemuMonitorIORead(qemuMonitorPtr mon) if (avail < 1024) { if (mon->bufferLength >= QEMU_MONITOR_MAX_RESPONSE) { - virReportSystemError(ERANGE, - _("No complete monitor response found in %d bytes"), - QEMU_MONITOR_MAX_RESPONSE); + virReportError(VIR_ERR_INTERNAL_ERROR, + _("QEMU monitor reply exceeds buffer size (%d bytes)"), + QEMU_MONITOR_MAX_RESPONSE); return -1; } if (VIR_REALLOC_N(mon->buffer, -- 2.25.0
