Blanket blocking socketcall() caused regressions for all 32-bit applications trying to make sockets. In theory, glibc disables socketcall when running on kernel version >= 4.3. In practice, Debian/Fedora/Ubuntu all set glibc's "expected kernel version" to 3.2, so socketcall() is still used on most 32-bit glibc binaries shipped. https://salsa.debian.org/glibc-team/glibc/-/blob/sid/debian/sysdeps/linux.mk#L4 https://salsa.debian.org/glibc-team/glibc/-/blob/sid/debian/... https://src.fedoraproject.org/rpms/glibc/blob/rawhide/f/glibc.spec#_436 https://src.fedoraproject.org/rpms/glibc/blob/rawhide/f/glib...
