State: closed
Merged: No

Let guest programs use SIGRTMIN + 1 by swapping with SIGRTMAX - 1. Since QEMU links against glibc, it reserves the signal for itself and returns EINVAL (as noted in the commit message). This means various applications that use SIGRTMIN + 1 cannot run on QEMU, including G-WAN web server and Open TFTP.
