Based on a patch for udev in
|
||
|
|
nixpkgs(upstart)/pkgs/os-specific/linux/udev/pre-accept4-kernel.patch
|
||
|
|
|
||
|
|
It was taken from:
|
||
|
|
https://github.com/archlinuxarm/PKGBUILDs/blob/master/core/udev-oxnas/pre-accept4-kernel.patch
|
||
|
|
|
||
|
|
Basically, ARM implemented accept4() only in 2.6.36. Nixpkgs now uses
|
||
|
|
linux headers from 2.6.35. And the particular nixpkgs glibc version had a bug,
|
||
|
|
not checking about 2.6.36 for accept4 on arm.
