      unix: add IoctlGetInt and IoctlSetInt on Linux · a55a7608
      Matt Layher authored 
      This CL adds basic integer get/set functions which wrap a generic
ioctl call.  The API is similar the one introduced for solaris/amd64
in CL 14587, but the request parameter has been changed to a uint
instead of an int.  This makes requests with a number larger than the
maximum signed 32-bit integer work on linux/386.

For consistency, the solaris/amd64 API has also been updated to make
use of a uint instead of an int for the request number.

Fixes golang/go#20474

      unix: add support for Linux filesystem encryption · 8c0a5eac
      joerichey@google.com authored 
      This CL adds in the necessary types and constants to support Linux
filesystem encryption. This includes the structs for the keys and
polices as well as the constants for key size and encryption algorithms.

This code also reduces the scope of some of the regexes in mkerrors.sh.
This is to reduce the number of unrelated constants added in with this
change.

Note that due to a bug in the Linux uapi headers, not all of the
necessary constants and structures are declared in linux/fs.h despite
being part of the kernel ABI. This means that some constants and types
had to be manually added in.

The bug has been patched (https://patchwork.kernel.org/patch/9662723),
and the manual additions can be removed when the patch is merged into
the mainline kernel.

      unix: generate all Linux go files from source · ea9bcade
      Joe Richey authored 
      Right now the process for adding in new constants, errors, or syscalls
for Linux is a pain and unreliable. The scripts are designed to be run
on the target architecture and use the header files installed on the
user's system. This makes it hard to generate files for all the
architectures or to have consistency between users. See golang/go#15282.

This CL fixes this issue by making all of the files for the 11 supported
architectures directly from source checkouts of Linux, glibc, and bluez.
This is done using Docker, the gcc cross-compilers, and qemu emulation.
Previously discussed here:
    https://go-review.googlesource.com/c/37589/

A README.md file is also added to explain how all the parts of the build
system work.

In order to get the build working for all the architectures, I made
some changes to the other scripts called from mkall_linux.go:
  - Files only used for generating linux code, moved to linux/
  - linux/mksysnum.pl supports a specified CC compiler.
  - The generated C code in mkerrors.sh changed to avoid a warning
  - mkerrors.sh headers changed to fix powerpc64 bug in sys/ioctl.h
  - linux/types.go no longer needs to export Ptrace structs in lowercase

Build instructions:
  - Host system needs to be x86-64 Linux
  - Install Docker (https://docs.docker.com/engine/installation/)
  - ./mkall.sh (That's it!!!)

      unix: update syscall numbers to 4.10 kernel · 21f2569f
      Joe Richey authored 
      The syscall numbers for Linux were out of date, so with the release of
the 4.10 kernel, now seemed like a reasonable time to update them. Note
that this change is mostly additive except that it removes some invalid
syscalls for arm, and it removes all constants that refer to either the
syscall base or total number of syscalls. Previous versions had only
removed some of them.

The updated syscall numbers were pulled directly from a header build
of the 4.10 kernel. This required some minor adjustements to the sysnum
generating perl script and is why the comments at the tops of the
generated files look slightly different. I could include the script I
used to do this, but right now it cannot generate the zerrors and ztypes
files.
