-Subject: [PATCH] qemu-nbd: Ignore SIGPIPE
-
-qemu proper has done so for 13 years
-(8a7ddc38a60648257dc0645ab4a05b33d6040063), qemu-img and qemu-io have
-done so for four years (526eda14a68d5b3596be715505289b541288ef2a).
-Ignoring this signal is especially important in qemu-nbd because
-otherwise a client can easily take down the qemu-nbd server by dropping
-the connection when the server wants to send something, for example:
-
-$ qemu-nbd -x foo -f raw -t null-co:// &
-[1] 12726
-$ qemu-io -c quit nbd://localhost/bar
-can't open device nbd://localhost/bar: No export with name 'bar' available
-[1] + 12726 broken pipe qemu-nbd -x foo -f raw -t null-co://
-
-In this case, the client sends an NBD_OPT_ABORT and closes the
-connection (because it is not required to wait for a reply), but the
-server replies with an NBD_REP_ACK (because it is required to reply).
