  "message": "linux-user: Tolerate CONFIG_LSM_MMAP_MIN_ADDR\n\nRunning qemu-i386 on a system running with SELinux in enforcing mode\n(more precisely: s390x trixie container on Fedora 40) fails with:\n\n    qemu-i386: tests/tcg/i386-linux-user/sigreturn-sigmask: Unable to find a guest_base to satisfy all guest address mapping requirements\n      00000000-ffffffff\n\nThe reason is that main() determines mmap_min_addr from\n/proc/sys/vm/mmap_min_addr, but SELinux additionally defines\nCONFIG_LSM_MMAP_MIN_ADDR, which is normally larger: 32K or 64K, but,\nin general, can be anything. There is no portable way to query its\nvalue: /boot/config, /proc/config and /proc/config.gz are distro- and\nenvironment-specific.\n\nOnce the identity map fails, the magnitude of guest_base does not\nmatter, so fix by starting the search from 1M or 1G.\n\nCc: qemu-stable@nongnu.org\nResolves: https://gitlab.com/qemu-project/qemu/-/issues/2598\nSuggested-by: Richard Henderson \u003crichard.henderson@linaro.org\u003e\nSigned-off-by: Ilya Leoshkevich \u003ciii@linux.ibm.com\u003e\nMessage-ID: \u003c20241023002558.34589-1-iii@linux.ibm.com\u003e\nSigned-off-by: Richard Henderson \u003crichard.henderson@linaro.org\u003e\n",
