+

+ LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
+ ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
+ INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
+ REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
+ PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
+ THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
+ HEREUNDER.
+
+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator
+and subsequent owner(s) (each and all, an "owner") of an original work of
+authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for
+the purpose of contributing to a commons of creative, cultural and
+scientific works ("Commons") that the public can reliably and without fear
+of later claims of infringement build upon, modify, incorporate in other
+works, reuse and redistribute as freely as possible in any form whatsoever
+and for any purposes, including without limitation commercial purposes.
+These owners may contribute to the Commons to promote the ideal of a free
+culture and the further production of creative, cultural and scientific
+works, or to gain reputation or greater distribution for their Work in
+part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any
+expectation of additional consideration or compensation, the person
+associating CC0 with a Work (the "Affirmer"), to the extent that he or she
+is an owner of Copyright and Related Rights in the Work, voluntarily
+elects to apply CC0 to the Work and publicly distribute the Work under its
+terms, with knowledge of his or her Copyright and Related Rights in the
+Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+protected by copyright and related or neighboring rights ("Copyright and
+Related Rights"). Copyright and Related Rights include, but are not
+limited to, the following:
+
+ i. the right to reproduce, adapt, distribute, perform, display,
+ communicate, and translate a Work;
+ ii. moral rights retained by the original author(s) and/or performer(s);
+iii. publicity and privacy rights pertaining to a person's image or
+ likeness depicted in a Work;
+ iv. rights protecting against unfair competition in regards to a Work,
+ subject to the limitations in paragraph 4(a), below;
+ v. rights protecting the extraction, dissemination, use and reuse of data
+ in a Work;
+ vi. database rights (such as those arising under Directive 96/9/EC of the
+ European Parliament and of the Council of 11 March 1996 on the legal
+ protection of databases, and under any national implementation
+ thereof, including any amended or successor version of such
+ directive); and
+vii. other similar, equivalent or corresponding rights throughout the
+ world based on applicable law or treaty, and any national
+ implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention
+of, applicable law, Affirmer hereby overtly, fully, permanently,
+irrevocably and unconditionally waives, abandons, and surrenders all of
+Affirmer's Copyright and Related Rights and associated claims and causes
+of action, whether now known or unknown (including existing as well as
+future claims and causes of action), in the Work (i) in all territories
+worldwide, (ii) for the maximum duration provided by applicable law or
+treaty (including future time extensions), (iii) in any current or future
+medium and for any number of copies, and (iv) for any purpose whatsoever,
+including without limitation commercial, advertising or promotional
+purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
+member of the public at large and to the detriment of Affirmer's heirs and
+successors, fully intending that such Waiver shall not be subject to
+revocation, rescission, cancellation, termination, or any other legal or
+equitable action to disrupt the quiet enjoyment of the Work by the public
+as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason
+be judged legally invalid or ineffective under applicable law, then the
+Waiver shall be preserved to the maximum extent permitted taking into
+account Affirmer's express Statement of Purpose. In addition, to the
+extent the Waiver is so judged Affirmer hereby grants to each affected
+person a royalty-free, non transferable, non sublicensable, non exclusive,
+irrevocable and unconditional license to exercise Affirmer's Copyright and
+Related Rights in the Work (i) in all territories worldwide, (ii) for the
+maximum duration provided by applicable law or treaty (including future
+time extensions), (iii) in any current or future medium and for any number
+of copies, and (iv) for any purpose whatsoever, including without
+limitation commercial, advertising or promotional purposes (the
+"License"). The License shall be deemed effective as of the date CC0 was
+applied by Affirmer to the Work. Should any part of the License for any
+reason be judged legally invalid or ineffective under applicable law, such
+partial invalidity or ineffectiveness shall not invalidate the remainder
+of the License, and in such case Affirmer hereby affirms that he or she
+will not (i) exercise any of his or her remaining Copyright and Related
+Rights in the Work or (ii) assert any associated claims and causes of
+action with respect to the Work, in either case contrary to Affirmer's
+express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+
+ a. No trademark or patent rights held by Affirmer are waived, abandoned,
+ surrendered, licensed or otherwise affected by this document.
+ b. Affirmer offers the Work as-is and makes no representations or
+ warranties of any kind concerning the Work, express, implied,
+ statutory or otherwise, including without limitation warranties of
+ title, merchantability, fitness for a particular purpose, non
+ infringement, or the absence of latent or other defects, accuracy, or
+ the present or absence of errors, whether or not discoverable, all to
+ the greatest extent permissible under applicable law.
+ c. Affirmer disclaims responsibility for clearing rights of other persons
+ that may apply to the Work or any use thereof, including without
+ limitation any person's Copyright and Related Rights in the Work.
+ Further, Affirmer disclaims responsibility for obtaining any necessary
+ consents, permissions or other rights required for any use of the
+ Work.
+ d. Affirmer understands and acknowledges that Creative Commons is not a
+ party to this document and has no duty or obligation with respect to
+ this CC0 or use of the Work.

+### chacha20 - ChaCha20
+#### Yawning Angel (yawning at schwanenlied dot me)
+
+Yet another Go ChaCha20 implementation. Everything else I found was slow,
+didn't support all the variants I need to use, or relied on cgo to go fast.
+
+Features:
+
+ * 20 round, 256 bit key only. Everything else is pointless and stupid.
+ * IETF 96 bit nonce variant.
+ * XChaCha 24 byte nonce variant.
+ * SSE2 and AVX2 support on amd64 targets.
+ * Incremental encrypt/decrypt support, unlike golang.org/x/crypto/salsa20.

+
+ As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+ "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+ An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+ A "Combined Work" is a work produced by combining or linking an

+
+ The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+ The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.

+ 1. Exception to Section 3 of the GNU GPL.
+
+ You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+ 2. Conveying Modified Versions.
+
+ If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:

+ a) under this License, provided that you make a good faith effort to
+ ensure that, in the event an Application does not supply the
+ function or data, the facility still operates, and performs

+# ratelimit
+--
+ import "github.com/juju/ratelimit"
+
+The ratelimit package provides an efficient token bucket implementation. See
+http://en.wikipedia.org/wiki/Token_bucket.
+
+## Usage
+
+#### func Reader
+
+```go
+func Reader(r io.Reader, bucket *Bucket) io.Reader
+```
+Reader returns a reader that is rate limited by the given token bucket. Each
+token in the bucket represents one byte.
+
+#### func Writer
+
+```go
+func Writer(w io.Writer, bucket *Bucket) io.Writer
+```
+Writer returns a writer that is rate limited by the given token bucket. Each
+token in the bucket represents one byte.
+
+#### type Bucket
+
+```go
+type Bucket struct {
+}
+```
+
+Bucket represents a token bucket that fills at a predetermined rate. Methods on
+Bucket may be called concurrently.
+
+#### func NewBucket
+
+```go
+func NewBucket(fillInterval time.Duration, capacity int64) *Bucket
+```
+NewBucket returns a new token bucket that fills at the rate of one token every
+fillInterval, up to the given maximum capacity. Both arguments must be positive.
+The bucket is initially full.
+
+#### func NewBucketWithQuantum
+
+```go
+func NewBucketWithQuantum(fillInterval time.Duration, capacity, quantum int64) *Bucket
+```
+NewBucketWithQuantum is similar to NewBucket, but allows the specification of
+the quantum size - quantum tokens are added every fillInterval.
+
+#### func NewBucketWithRate
+
+```go
+func NewBucketWithRate(rate float64, capacity int64) *Bucket
+```
+NewBucketWithRate returns a token bucket that fills the bucket at the rate of
+rate tokens per second up to the given maximum capacity. Because of limited
+clock resolution, at high rates, the actual rate may be up to 1% different from
+the specified rate.
+
+#### func (*Bucket) Rate
+
+```go
+func (tb *Bucket) Rate() float64
+```
+Rate returns the fill rate of the bucket, in tokens per second.
+
+#### func (*Bucket) Take
+
+```go
+func (tb *Bucket) Take(count int64) time.Duration
+```
+Take takes count tokens from the bucket without blocking. It returns the time
+that the caller should wait until the tokens are actually available.
+
+Note that if the request is irrevocable - there is no way to return tokens to
+the bucket once this method commits us to taking them.
+
+#### func (*Bucket) TakeAvailable
+
+```go
+func (tb *Bucket) TakeAvailable(count int64) int64
+```
+TakeAvailable takes up to count immediately available tokens from the bucket. It
+returns the number of tokens removed, or zero if there are no available tokens.
+It does not block.
+
+#### func (*Bucket) TakeMaxDuration
+
+```go
+func (tb *Bucket) TakeMaxDuration(count int64, maxWait time.Duration) (time.Duration, bool)
+```
+TakeMaxDuration is like Take, except that it will only take tokens from the
+bucket if the wait time for the tokens is no greater than maxWait.
+
+If it would take longer than maxWait for the tokens to become available, it does
+nothing and reports false, otherwise it returns the time that the caller should
+wait until the tokens are actually available, and reports true.
+
+#### func (*Bucket) Wait
+
+```go
+func (tb *Bucket) Wait(count int64)
+```
+Wait takes count tokens from the bucket, waiting until they are available.
+
+#### func (*Bucket) WaitMaxDuration
+
+```go
+func (tb *Bucket) WaitMaxDuration(count int64, maxWait time.Duration) bool
+```
+WaitMaxDuration is like Wait except that it will only take tokens from the
+bucket if it needs to wait for no greater than maxWait. It reports whether any
+tokens have been removed from the bucket If no tokens have been removed, it
+returns immediately.

+// in short, bounded-constant time (Bucket.Wait benchmarks at 175ns on
+// my laptop).

+// Time is measured in equal measured ticks, a given interval
+// (fillInterval) apart. On each tick a number of tokens (quantum) are
+// added to the bucket.

+// When any of the methods are called the bucket updates the number of

+# Building `sys/unix`
+
+The sys/unix package provides access to the raw system call interface of the
+underlying operating system. See: https://godoc.org/golang.org/x/sys/unix
+
+Porting Go to a new architecture/OS combination or adding syscalls, types, or
+constants to an existing architecture/OS pair requires some manual effort;
+however, there are tools that automate much of the process.
+
+## Build Systems
+
+There are currently two ways we generate the necessary files. We are currently
+migrating the build system to use containers so the builds are reproducible.
+This is being done on an OS-by-OS basis. Please update this documentation as
+components of the build system change.
+
+### Old Build System (currently for `GOOS != "Linux" || GOARCH == "sparc64"`)
+
+The old build system generates the Go files based on the C header files
+present on your system. This means that files
+for a given GOOS/GOARCH pair must be generated on a system with that OS and
+architecture. This also means that the generated code can differ from system
+to system, based on differences in the header files.
+
+To avoid this, if you are using the old build system, only generate the Go
+files on an installation with unmodified header files. It is also important to
+keep track of which version of the OS the files were generated from (ex.
+Darwin 14 vs Darwin 15). This makes it easier to track the progress of changes
+and have each OS upgrade correspond to a single change.
+
+To build the files for your current OS and architecture, make sure GOOS and
+GOARCH are set correctly and run `mkall.sh`. This will generate the files for
+your specific system. Running `mkall.sh -n` shows the commands that will be run.
+
+Requirements: bash, perl, go
+
+### New Build System (currently for `GOOS == "Linux" && GOARCH != "sparc64"`)
+
+The new build system uses a Docker container to generate the go files directly
+from source checkouts of the kernel and various system libraries. This means
+that on any platform that supports Docker, all the files using the new build
+system can be generated at once, and generated files will not change based on
+what the person running the scripts has installed on their computer.
+
+The OS specific files for the new build system are located in the `${GOOS}`
+directory, and the build is coordinated by the `${GOOS}/mkall.go` program. When
+the kernel or system library updates, modify the Dockerfile at
+`${GOOS}/Dockerfile` to checkout the new release of the source.
+
+To build all the files under the new build system, you must be on an amd64/Linux
+system and have your GOOS and GOARCH set accordingly. Running `mkall.sh` will
+then generate all of the files for all of the GOOS/GOARCH pairs in the new build
+system. Running `mkall.sh -n` shows the commands that will be run.
+
+Requirements: bash, perl, go, docker
+
+## Component files
+
+This section describes the various files used in the code generation process.
+It also contains instructions on how to modify these files to add a new
+architecture/OS or to add additional syscalls, types, or constants. Note that
+if you are using the new build system, the scripts cannot be called normally.
+They must be called from within the docker container.
+
+### asm files
+
+The hand-written assembly file at `asm_${GOOS}_${GOARCH}.s` implements system
+call dispatch. There are three entry points:
+```
+ func Syscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
+ func Syscall6(trap, a1, a2, a3, a4, a5, a6 uintptr) (r1, r2, err uintptr)
+ func RawSyscall(trap, a1, a2, a3 uintptr) (r1, r2, err uintptr)
+```
+The first and second are the standard ones; they differ only in how many
+arguments can be passed to the kernel. The third is for low-level use by the
+ForkExec wrapper. Unlike the first two, it does not call into the scheduler to
+let it know that a system call is running.
+
+When porting Go to an new architecture/OS, this file must be implemented for
+each GOOS/GOARCH pair.
+
+### mksysnum
+
+Mksysnum is a script located at `${GOOS}/mksysnum.pl` (or `mksysnum_${GOOS}.pl`
+for the old system). This script takes in a list of header files containing the
+syscall number declarations and parses them to produce the corresponding list of
+Go numeric constants. See `zsysnum_${GOOS}_${GOARCH}.go` for the generated
+constants.
+
+Adding new syscall numbers is mostly done by running the build on a sufficiently
+new installation of the target OS (or updating the source checkouts for the
+new build system). However, depending on the OS, you make need to update the
+parsing in mksysnum.
+
+### mksyscall.pl
+
+The `syscall.go`, `syscall_${GOOS}.go`, `syscall_${GOOS}_${GOARCH}.go` are
+hand-written Go files which implement system calls (for unix, the specific OS,
+or the specific OS/Architecture pair respectively) that need special handling
+and list `//sys` comments giving prototypes for ones that can be generated.
+
+The mksyscall.pl script takes the `//sys` and `//sysnb` comments and converts
+them into syscalls. This requires the name of the prototype in the comment to
+match a syscall number in the `zsysnum_${GOOS}_${GOARCH}.go` file. The function
+prototype can be exported (capitalized) or not.
+
+Adding a new syscall often just requires adding a new `//sys` function prototype
+with the desired arguments and a capitalized name so it is exported. However, if
+you want the interface to the syscall to be different, often one will make an
+unexported `//sys` prototype, an then write a custom wrapper in
+`syscall_${GOOS}.go`.
+
+### types files
+
+For each OS, there is a hand-written Go file at `${GOOS}/types.go` (or
+`types_${GOOS}.go` on the old system). This file includes standard C headers and
+creates Go type aliases to the corresponding C types. The file is then fed
+through godef to get the Go compatible definitions. Finally, the generated code
+is fed though mkpost.go to format the code correctly and remove any hidden or
+private identifiers. This cleaned-up code is written to
+`ztypes_${GOOS}_${GOARCH}.go`.
+
+The hardest part about preparing this file is figuring out which headers to
+include and which symbols need to be `#define`d to get the actual data
+structures that pass through to the kernel system calls. Some C libraries
+preset alternate versions for binary compatibility and translate them on the
+way in and out of system calls, but there is almost always a `#define` that can
+get the real ones.
+See `types_darwin.go` and `linux/types.go` for examples.
+
+To add a new type, add in the necessary include statement at the top of the
+file (if it is not already there) and add in a type alias line. Note that if
+your type is significantly different on different architectures, you may need
+some `#if/#elif` macros in your include statements.
+
+### mkerrors.sh
+
+This script is used to generate the system's various constants. This doesn't
+just include the error numbers and error strings, but also the signal numbers
+an a wide variety of miscellaneous constants. The constants come from the list
+of include files in the `includes_${uname}` variable. A regex then picks out
+the desired `#define` statements, and generates the corresponding Go constants.
+The error numbers and strings are generated from `#include `, and the
+signal numbers and strings are generated from `#include `. All of
+these constants are written to `zerrors_${GOOS}_${GOARCH}.go` via a C program,
+`_errors.c`, which prints out all the constants.
+
+To add a constant, add the header that includes it to the appropriate variable.
+Then, edit the regex (if necessary) to match the desired constant. Avoid making
+the regex too broad to avoid matching unintended constants.
+
+
+## Generated files
+
+### `zerror_${GOOS}_${GOARCH}.go`
+
+A file containing all of the system's generated error numbers, error strings,
+signal numbers, and constants. Generated by `mkerrors.sh` (see above).
+
+### `zsyscall_${GOOS}_${GOARCH}.go`
+
+A file containing all the generated syscalls for a specific GOOS and GOARCH.
+Generated by `mksyscall.pl` (see above).
+
+### `zsysnum_${GOOS}_${GOARCH}.go`
+
+A list of numeric constants for all the syscall number of the specific GOOS
+and GOARCH. Generated by mksysnum (see above).
+
+### `ztypes_${GOOS}_${GOARCH}.go`
+
+A file containing Go types for passing into (or returning from) syscalls.
+Generated by godefs and the types file (see above).

+# (like syscall_darwin.go) and generates system call bodies.
+# The prototypes are marked by lines beginning with "//sys"
+# and read like func declarations if //sys is replaced by func, but:
+# * The parameter lists must give a name for each argument.
+# This includes return parameters.
+# * The parameter lists must give a type for each argument:
+# the (x, y, z int) shorthand is not allowed.
+# * If the return parameter is an error number, it must be named errno.
+
+# A line beginning with //sysnb is like //sys, except that the
+# goroutine will not be suspended during the execution of the system
+# call. This must only be used for system calls which can never
+# block, as otherwise the system call could cause all goroutines to
+# hang.

+// SockaddrALG implements the Sockaddr interface for AF_ALG type sockets.
+// SockaddrALG enables userspace access to the Linux kernel's cryptography
+// subsystem. The Type and Name fields specify which type of hash or cipher
+// should be used with a given socket.
+//
+// To create a file descriptor that provides access to a hash or cipher, both
+// Bind and Accept must be used. Once the setup process is complete, input
+// data can be written to the socket, processed by the kernel, and then read
+// back as hash output or ciphertext.
+//
+// Here is an example of using an AF_ALG socket with SHA1 hashing.
+// The initial socket setup process is as follows:
+//
+// // Open a socket to perform SHA1 hashing.
+// fd, _ := unix.Socket(unix.AF_ALG, unix.SOCK_SEQPACKET, 0)
+// addr := &unix.SockaddrALG{Type: "hash", Name: "sha1"}
+// unix.Bind(fd, addr)
+// // Note: unix.Accept does not work at this time; must invoke accept()
+// // manually using unix.Syscall.
+// hashfd, _, _ := unix.Syscall(unix.SYS_ACCEPT, uintptr(fd), 0, 0)
+//
+// Once a file descriptor has been returned from Accept, it may be used to
+// perform SHA1 hashing. The descriptor is not safe for concurrent use, but
+// may be re-used repeatedly with subsequent Write and Read operations.
+//
+// When hashing a small byte slice or string, a single Write and Read may
+// be used:
+//
+// // Assume hashfd is already configured using the setup process.
+// hash := os.NewFile(hashfd, "sha1")
+// // Hash an input string and read the results. Each Write discards
+// // previous hash state. Read always reads the current state.
+// b := make([]byte, 20)
+// for i := 0; i < 2; i++ {
+// io.WriteString(hash, "Hello, world.")
+// hash.Read(b)
+// fmt.Println(hex.EncodeToString(b))
+// }
+// // Output:
+// // 2ae01472317d1935a84797ec1983ae243fc6aa28
+// // 2ae01472317d1935a84797ec1983ae243fc6aa28
+//
+// For hashing larger byte slices, or byte streams such as those read from
+// a file or socket, use Sendto with MSG_MORE to instruct the kernel to update
+// the hash digest instead of creating a new one for a given chunk and finalizing it.
+//
+// // Assume hashfd and addr are already configured using the setup process.
+// hash := os.NewFile(hashfd, "sha1")
+// // Hash the contents of a file.
+// f, _ := os.Open("/tmp/linux-4.10-rc7.tar.xz")
+// b := make([]byte, 4096)

+// n, err := f.Read(b)
