* Strip X-Forwarded auth headers from whitelisted paths
For any paths that match skip-auth-regex, strip normal
X-Forwarded headers that would be sent based on pass-user-headers
or pass-access-token settings. This prevents malicious injecting
of authentication headers through the skip-auth-regex paths in
cases where the regex might be misconfigured and too open.
Control this behavior with --skip-auth-strip-headers flag. This
flag is set to TRUE by default (this is secure by default, but
potentially breaks some legacy configurations).
Only x-Forwarded headers stripped, left the Authorization header
untouched.
* Strip authorization header if it would be set
* Improve TestStripAuthHeaders test table
* Improve --skip-auth-strip-headers flag documentation
* Encode sessions with MsgPack + LZ4
Assumes ciphers are now mandatory per #414. Cookie & Redis sessions
can fallback to V5 style JSON in error cases. TODO: session_state.go
unit tests & new unit tests for Legacy fallback scenarios.
* Only compress encoded sessions with Cookie Store
* Cleanup msgpack + lz4 error handling
* Change NewBase64Cipher to take in an existing Cipher
* Add msgpack & lz4 session state tests
* Add required options for oauthproxy tests
More aggressively assert.NoError on all
validation.Validate(opts) calls to enforce legal
options in all our tests.
Add additional NoError checks wherever error return
values were ignored.
* Remove support for uncompressed session state fields
* Improve error verbosity & add session state tests
* Ensure all marshalled sessions are valid
Invalid CFB decryptions can result in garbage data
that 1/100 times might cause message pack unmarshal
to not fail and instead return an empty session.
This adds more rigor to make sure legacy sessions
cause appropriate errors.
* Add tests for legacy V5 session decoding
Refactor common legacy JSON test cases to a
legacy helpers area under session store tests.
* Make ValidateSession a struct method & add CHANGELOG entry
* Improve SessionState error & comments verbosity
* Move legacy session test helpers to sessions pkg
Placing these helpers under the sessions pkg removed
all the circular import uses in housing it under the
session store area.
* Improve SignatureAuthenticator test helper formatting
* Make redis.legacyV5DecodeSession internal
* Make LegacyV5TestCase test table public for linter
* Implements --ip-whitelist option
* Included IPWhitelist option to allow one-or-more selected CIDR ranges
to bypass OAuth2 authentication.
* Adds IPWhitelist, a fast lookup table for multiple CIDR ranges.
* Renamed IPWhitelist ipCIDRSet
* Fixed unessesary pointer usage in ipCIDRSet
* Update CHANGELOG.md
* Update CHANGELOG.md
* Updated to not use err.Error() in printf statements
* Imrpoved language for --ip-whitelist descriptions.
* Improve IP whitelist options error messages
* Clarify options single-host normalization
* Wrote a book about ipCIDRSet
* Added comment to IsWhitelistedIP in oauthproxy.go
* Rewrite oauthproxy test case as table driven
* oops
* Support whitelisting by low-level remote address
* Added more test-cases, improved descriptions
* Move ip_cidr_set.go to pkg/ip/net_set.go
* Add more whitelist test use cases.
* Oops
* Use subtests for TestIPWhitelist
* Add minimal tests for ip.NetSet
* Use switch statment
* Renamed ip-whitelist to whitelist-ip
* Update documentation with a warning.
* Update pkg/apis/options/options.go
* Update CHANGELOG.md

* Add req.host to targetURL when redirecting to https
The req.URL.Host might not be present when redirecting to https if the
given req.URL is something like "/". In such scenario, the req.Host is
still present and valid.
This commit adds the original req.Host to the targetURL before returning
the 308 status, to avoid having a `Location: https:///` in the response.
* Bring back empty line
* Wrap the setting of targetURL.Host in a condition
* Add a comment to the test explaining why the redirectURL includes example.com
* Add changelog entry
A blank user agent is considered == to an empty string. When no -ping-user-agent option is specified, this is considered to be an empty string.
This reveals two problems:
- When no ping-user-agent is specified, main.go sets up a health check user agent of ""
- When no user agent is specified, the empty string is still checked against the health check user agents.
Now the health check middleware ignores blank user agents and paths in order to sanitise it's input to avoid this issue.
Additional tests have been added to verify these situations.
This also removes the check for the decoded from the valid secret size
check. The code was unreachable because encryption.SecretBytes will only
return the decoded secret if it was the right length after decoding.
Moves the logic for redirecting to HTTPs to a middleware package and adds tests for this logic.
Also makes the functionality more useful, previously it always redirected to the HTTPS address of the proxy, which may not have been intended, now it will redirect based on if a port is provided in the URL (assume public facing 80 to 443 or 4180 to 8443 for example)

When using the configured provider JWT Verifier, it makes
sense to use the provider `CreateSessionStateFromBearerToken`
method. For any extra JWT Issuers, they should use a generic
default verifier.
This helper method is only applicable for Base64 wrapped
encryption since it operated on string -> string primarily.
It wouldn't be used for pure CFB/GCM ciphers. After a messagePack
session refactor, this method would further only be used for
legacy session compatibility - making its placement in cipher.go
not ideal.
