+Subject: libkmod: Avoid calling syscall() with -1
+
+At least in qemu 1.4.1 for vexpress/arm-cortexa9, this resulted in an
+illegal instruction error. Solve that by returning an error when
+__NR_finit_module is -1.

This bug caused udev to fail to load any module, crashing with Illegal instruction. The patch was taken from upstream and should be integrated in the next version of kmod (version 14) Signed-off-by: Jérémy Rosen <jeremy.rosen@openwide.fr> --- This bug went undetected because it only triggers when modules are loaded via libkmod and buildroot will use busybox to implement modprobe. --- package/kmod/kmod-001-no-syscall--1.patch | 31 +++++++++++++++++++++++++++++ 1 file changed, 31 insertions(+) create mode 100644 package/kmod/kmod-001-no-syscall--1.patch
