* only byte read has been tested
Updated .ld file to work better with platform.io; however, I am still
missing some steps, so platformio will still fail.
* Interesting glitch in boards.txt after github merge. A new board in
master was missing new additions added by boards.txt.py in the PR.
Which the CI flags when it rebuilds boards.txt.

Several fixes and improvements to example MMU48K.
With the improved optimization in toolchain 10.1 The example divide by 0
exception was failing with a HWDT event instead of its exception handler.
The compiler saw the obscured divide by 0 and replaced it with a break point.

* Deprecate SPIFFS, move examples to LittleFS
SPIFFS has been a great filesystem, but it has significant problems in
many cases (and it's also pretty slow). Development seems to have
slowed/stopped on the upstream version, and we're not able to provide
support or fix the known issues with it as-is.
Deprecate SPIFFS variable.
Update all examples to use LittleFS instead of SPIFFS.
Also, minor cleanup on very old examples which has obsolete delays
waiting for the Serial port to come up, or which were stuck at 9600 baud
because of their ancient AVR heritage.

Use the proper api (::clear(), isEmpty()) instead of doing
comparisons/assignments of empty strings. Also fix mixture
of tabs and spaces in the source code.
* Add const char* content to ESP8266WebSerer::send()
Supercedes #3492
Allow sending raw binary data or strings directly without conversion to
a String to reduce memory overhead when possible.
From original @timw1971 PR #3492
Added public functions to allow content to be uploaded using const
char*. For some cases, this can remove the need for content to be copied
into a String, and thus can be considerably more space-efficient.
* Fix example formatting
* Make GIF example use static const array
* Make the example really need to use const char*
Make the generated GIF dynamic in the example and move the original to
PROGMEM (since that's where const arrays like this belong).
* 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
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
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.
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.
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.
