Fixes#2567
Allow the web server to send plain C strings instead of requring they be
encapsulated inside a String class object. Saves memory vs. having to
convert C strings to Strings (i.e. duplication of data), overloads on
the efficient sendContent_P(char*) methods.
* Convert ESP8266WebServer* into templatized model
Supercedes #4912
Refactor the three versions of ESP8266WebServer and *WebServerSecure to a
single templated class. Use "using" to enable old, non-templated names to b
used (so no user changes required to compile or run).
Fixes#4908 and clean up the code base a lot.
Basic tests run (the ones in the example code).
No code changes are required in userland except for setting the SSL
certificates which now use a cleaner "getServer()" accessor and lets the
app use the native BearSSL calls on the WiFiClientSecure object.
@devyte should be proud, it removes virtuals and even has template specialization...
* Fix HTTPUpdate templates and examples
* Fix HTTPUpdateServer library build
Need to remove dot-a linkage since there are no .cpp files in the
directory anymore due to templates.
* Provide backward-compat names for updt template
Allow existing code to use the same well known names for
HTTPUpdateSecure.
* Remove ClientType from all templates, auto-infer
Remove the ClientType template parameter from all objects. Simplifies
the code and makes it more foolproof.
Add a "using" in each server to define the type of connection returned
by all servers, which is then used in the above templates automatically.
* Can safely include FS.h now that SD/SPIFFS unified
* Move the templates/objects to their own namespaces
* Fix merge issues with untemplated methods
* Address review comments
* Fix mock test, remove warnings inside test dir
Make the simple mock test CI job pass and clean up
any spurious warnings in the test directory.
There still are warnings in the libraries and core, but they
should be addressed in a separate PR.
-Expose HTTP Digest authentication with H1 hash as the argument
-Preserved HTTP authentication with username/password arguments
-Added a public static function for generating the H1 hash
-Created an example of how to use this called HttpHashCredAuth.ino

* esp8266:coreVersionNumeric(): add a define and comment-example to check on its usability
Content length provides context into the size of the upload, it's not
the exact form body size it's off by the request header info, but it was
already parsed by the library and provides little to no additional
overhead to pass on for use in request handlers.
Currently post args are only available at the end of upload but they are already listed - this PR just expose them with minimal changes
It also set a define for post args array size originaly set to 32

BearSSLX509List, BearSSLSession, BearSSLPublicKey, and BearSSLPrivateKey
were all in the global namespace and not in the BearSSL:: one, due to an
oversight when they were originally created. Move them to the proper
namespace with the following mapping:
BearSSLX509List => BearSSL::X509List
BearSSLSession => BearSSL::Session
BearSSLPublicKey => BearSSL::PublicKey
BearSSLPrivateKey => BearSSL::PrivateKey

According to the GCC man page, __section__ attributes should only be used
for global variables. However, the PROGMEM and ICACHE_RODATA macros use
this variable decorator even for local variables. Most of the time it works,
but when a static or inlined function tries to use a PROGMEM/PSTR/etc.
variable the compiler can throw an error like:
error: XXX causes a section type conflict with YYY
Change the PROGMEM macro to emit a section name that is unique (a combo
of the file, line, and counter variables to ensure uniqueness). The
standard linker script will place them properly in .IROM without
any changes.
Fixes#5036 and others.
BearSSL (https://www.bearssl.org) is a TLS(SSL) library written by
Thomas Pornin that is optimized for lower-memory embedded systems
like the ESP8266. It supports a wide variety of modern ciphers and
is unique in that it doesn't perform any memory allocations during
operation (which is the unfortunate bane of the current axTLS).
BearSSL is also absolutely focused on security and by default performs
all its security checks on x.509 certificates during the connection
phase (but if you want to be insecure and dangerous, that's possible
too).
While it does support unidirectional SSL buffers, like axTLS,
as implemented the ESP8266 wrappers only support bidirectional
buffers. These bidirectional buffers avoid deadlocks in protocols
which don't have well separated receive and transmit periods.
This patch adds several classes which allow connecting to TLS servers
using this library in almost the same way as axTLS:
BearSSL::WiFiClientSecure - WiFiClient that supports TLS
BearSSL::WiFiServerSecure - WiFiServer supporting TLS and client certs
It also introduces objects for PEM/DER encoded keys and certificates:
BearSSLX509List - x.509 Certificate (list) for general use
BearSSLPrivateKey - RSA or EC private key
BearSSLPublicKey - RSA or EC public key (i.e. from a public website)
Finally, it adds a Certificate Authority store object which lets
BearSSL access a set of trusted CA certificates on SPIFFS to allow it
to verify the identity of any remote site on the Internet, without
requiring RAM except for the single matching certificate.
CertStoreSPIFFSBearSSL - Certificate store utility
Client certificates are supported for the BearSSL::WiFiClientSecure, and
what's more the BearSSL::WiFiServerSecure can also *require* remote clients
to have a trusted certificate signed by a specific CA (or yourself with
self-signing CAs).
Maximum Fragment Length Negotiation probing and usage are supported, but
be aware that most sites on the Internet don't support it yet. When
available, you can reduce the memory footprint of the SSL client or server
dramatically (i.e. down to 2-8KB vs. the ~22KB required for a full 16K
receive fragment and 512b send fragment). You can also manually set a
smaller fragment size and guarantee at your protocol level all data will
fit within it.
Examples are included to show the usage of these new features.
axTLS has been moved to its own namespace, "axtls". A default "using"
clause allows existing apps to run using axTLS without any changes.
The BearSSL::WiFi{client,server}Secure implements the axTLS
client/server API which lets many end user applications take advantage
of BearSSL with few or no changes.
The BearSSL static library used presently is stored at
https://github.com/earlephilhower/bearssl-esp8266 and can be built
using the standard ESP8266 toolchain.
* Fix WebServerSecure streamFile()
ESP8266WebServerSecure's streamFile was using the base class' method
which did not use SSL encrypt before transmitting, leading to failure.
Add a new template method and required support for
WiFiClientSecure::write(Stream&) (using a local temp buffer since the
SSL libs do not grok Arduino Streams at all).
Fixes#4544
* Match ClientContext buffer and yield() behavior
ClientContext sends out 256 bytes at a time and gives a yield after
each chunk to ensure the WDT doesn't fire. Mimic that behavior in
WiFiClientSecure::write(Stream&).
Use platform.local.txt to add -Werror to GCC for the build of all
code. Any warnings on a submitted patch will cause an error.
Several examples and libraries had warnings/errors (missing returns
on functions, types, etc.). Clean those up with this commit as well.
In issue #4350, @mongozmaki found that the web server was accessing a
deleted variable in the destructor. Implement his suggested change
and move the close() before any freeing. Could also have simply
NULL'd out the _currentHeaders member after freeing as well.
Fixes issue #4350
* add begin(port) to esp8266webserver, move some strings to flash, some refactoring
* Moved more strings to flash, unified some strings
* move mimetable strings into a standalone file
* more string moves to flash, remove duplicates, refactor of template method, minor styling
* Reverted moving small string to flash (no heap advantage, reduces bin size)
The server needs to load an X509 and RSA key, but instead of using
the existing loadObject() calls implemented its own. Remove them and
use the standard ones instead.
The DEBUG_OUTPUT macro was undefined in the SSL Web server. Add it
in do that when you compile with DEBUG=HTTP_SERVER it actually compiles.
Adds SSL server mode for WiFiServerSecure, for plain SSL connections,
ESP8266WebServerSecure, for HTTPS web serving, and SecureHTTPSUpdater for
encrypted OTA updates.
Example code is provided for all new options, as well as a BASH script for
generating their own, self-signed certificates.
Both ESP8266WebServerSecure and SecureHTTPSUpdater are important for secure
password-based authentication. HTTP Basic Authentication, the only supported
model presently, sends the username and password in *cleartext* and therefore
should *never* be used in any un-SSL encrypted channel unless you don't mind
sharing your login and password with anyone else on the internet. Even if the
ESP8266 is not safety critical, this cleartext broadcast could expose you should
you reuse this password elsewhere on your network or the internet.
* Make HTTP server test data easier to examine
* Add HTTP server parameter tests containing & and =
* Fix URL parameter decoding in web server
The parameters string needs to be first split on & and =, and URL
decoding on parts done after that. Otherwise URL encoded & and = within
parameter names and values cause incorrect splitting.
* Added constant time strings comparison to avoid possible time-based attacks
* Fixed data types
* Fixed indentation
* Moved string comnparison in constant time to String class; modified function body to assure constant time comparison despite compiler optimizations
* Removed wrong code
* Fixed error and prevented compiler optimization to delete u1 local variable
* Avoid timing attacks on string comparison
* Minor
* changed counter names, removed else
* Add Digest Auth
* Check for Opaque and Nonce
* Remove Serial Debug and fix Indentation
* Added example sketch with documentation,Fixed indentation and Defaults
* Digest Authentication minor changes + new padded 32 digit random function
* update license to public domain
* renaming functions
The extension -> MIME type routine uses lots of constant strings which end
up in the RODATA segment of RAM. Refactor the comparison to use a table of
strings stored in PMMEM instead, freeing ~370 bytes for the heap.
