2018-04-24luci-base: ensure that file upload values have lengthJo-Philipp Wich
Ensure that the (table) length of a file upload value has nonzero length by initializing the first table index with the file name. This fixes tests in the form x = luci.http.formvalue(...) if x and #x > 0 then ... end Fixes #1763. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-22luci-base: decode plus signs in x-www-form-urlencoded POST dataJo-Philipp Wich
Depends on 5ef51b2ab ("lucihttp: update to latest HEAD"). Fixes #1755. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-19luci-base: properly handle repeated POST parametersJo-Philipp Wich
Restore the old luci.http behaviour of converting repeated POST params into single tables holding all values instead of letting each repeated parameter overwrite the value of the preceeding one. Fixes, among other things, the handling of CBI dynamic list values. Fixes #1752 Fixes 59dea0230 ("luci-base: switch to lucihttp based POST data processing") Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-19luci-base: implement session handling in luci.model.uciJo-Philipp Wich
Introduce luci.model.uci.set_session_id() and luci.model.uci.get_session_id() to set and get the effective session ID respectively. When a session ID is set, it is sent as `ubus_rpc_session` attribute to rpcd, causing it to use per-session change directories, isolating LuCI changes from the global system uci state. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-18libs: move http.protocol.{date,mime,conditionals} to luci-lib-httpprotoutilsJo-Philipp Wich
Also adjust the dependencies of components depending on these classes and flatten the namespace from luci.http.protocol.* to luci.http.* Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-18luci-base: fold luci.http.protocol into luci.httpJo-Philipp Wich
With only the decoder routines remaining in luci.http.protocol, it makes no sense to keep the low level protocol class around, so fold the remaining code into the central luci.http class. Also adjust the few direct users of luci.http.protocol accordingly. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-18luci-base: refactor luci.httpJo-Philipp Wich
- Rewrite getcookie() to use liblucihttp header value parsing - Rewrite setfilehandler() to use local variables and have cleaner code - Fix build_querystring() to actually *en*code the given params Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-18luci-base: drop luci.util.dtable()Jo-Philipp Wich
The dtable() function has no user in the entire LuCI repo, so drop it. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-18luci-base: switch to lucihttp based POST data processingJo-Philipp Wich
Use the liblucihttp provided multipart and x-www-urlencoded body parsers and drop the old Lua parsing code. The C based data parsers are way faster than their old Lua counterparts while producing less string garbage and more correct results. While refactoring the luci.http.protocol code, also drop unused functions and dead code, heavily reducing the module size. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-18luci-base: switch to lucihttp.urldecode() and lucihttp.urlencode()Jo-Philipp Wich
Drop the Lua implementation in luci.http.protocol and use the optimized C variants of liblucihttp instead. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-10luci-base: fix rendering of 404 HTML error templateJo-Philipp Wich
This 404 error template rendering has been broken for a long time due to bad function environment level in luci.template when invoking the rendering from the toplevel dispatcher context. Fix this issue by adding a local function indirection, essentially adding an additional stack frame. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-10luci-base: error404: do not access request env directlyJo-Philipp Wich
Instead of attempting to access the request environment directly (which does not work anyway using the CGI SGI), use the already sanitized dispatcher.context.request property to print out the not found url. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-10luci-base: don't propagate null bytes in path informationJo-Philipp Wich
It is possible to inject unescaped markup using a double encoded null byte via PATH_INFO on certain leaf nodes. Since there is no legitimate reason to handle null bytes in any part of the requested url, simply skip over such bytes when parsing the PATH_INFO value. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-09luci-base: consider empty parameters as well when testing POST requirementJo-Philipp Wich
The cbi class will react on an empty "cbi.submit" parameter as well so we must intercept GET requests using that too. Fixes 186e690c0 ("luci-base: dispatcher: reject non-POST requests with any cbi.submit value") Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-07timezone data: update to 2018dHannu Nyman
Update timezone data to 2018d http://mm.icann.org/pipermail/tz-announce/2018-March/000049.html In 2018, Palestine starts DST on March 24, not March 31. Adjust future predictions accordingly. Casey Station in Antarctica changed from +11 to +08 Signed-off-by: Hannu Nyman <hannu.nyman@iki.fi>
2018-04-07luci-base: fix luci.model.uci.get_first()Jo-Philipp Wich
Properly propagate the config parameter to the foreach iterator in order to fix get_first() lookups. Fixes #1734. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-07luci-base: escape path strings and field parameterJo-Philipp Wich
Prevent various XSS vectors by not interpolating field and path values verbatim into script and html contexts. Signed-off-by: Jo-Philipp Wich <jo@mein.io>

2018-04-06luci-base: emit a warning if cbi() delegates a SimpleForm instanceJo-Philipp Wich
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-06luci-base: implement luci.model.uci.get_state()Jo-Philipp Wich
Introduce a get_state() function which can be used to access legacy uci state variables. This is usually not needed anymore but some packages (mainly mwan3) still rely on this. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-05luci-base: introduce luci.dispatcher.lookup()Jo-Philipp Wich
The lookup function takes multiple, possibly malformed path fragments, splits them on slashes, constructs a temporary path and looks up the result in the dispatch tree. If a matching node has been found, the function will return both the node reference and the canonical url to it. If no corresponding node is found, the function returns nil.

Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-05luci-base: introduce luci.util.shellquote()Jo-Philipp Wich
Introduce a new function luci.util.shellquote() which encloses the given string argument in single quotes and escapes any embedded single quote characters. This function is intended to be used when interpolating untrusted input into shell commands. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-05luci-base: fix possible shell injection in luci.tools.status.switch_status()Jo-Philipp Wich
Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-05luci-base: dispatcher: reject non-POST requests with any cbi.submit valueJo-Philipp Wich
Due to the fact that luci.model.cbi reacts on any "cbi.submit" value while the dispatcher only required POST for cbi.submit == 1, the CSRF token protection could be bypassed. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-04luci-base: use FULL_REQUEST_URI on login form templatesJo-Philipp Wich
Switch from using the REQUEST_URI CGI variable directly to the canonicalized FULL_REQUEST_URI property. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-04luci-base: add FULL_REQUEST_URI template propertyJo-Philipp Wich
Introduce a new template property FULL_REQUEST_URI which returns the full canonicalized request URL built from SCRIPT_NAME, PATH_INFO and QUERY_STRING. This new property is safer to use compared to using the raw REQUEST_URI CGI environment variable directly as this value is essentially untrusted user input which may contain embedded escaped slashes, double forward slashes and other oddities allowing XSS exploitation or request redirection. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-04luci-base: add a strict flag to the hostname validatorJo-Philipp Wich
Some applications, e.g. dnsmasq, do not allow hostnames starting with an underscore, therefor extend the existing hostname datatype validator with a `strict` which disallows a leading underscore. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
2018-04-04luci-base: switch to ubus uci operationsJo-Philipp Wich
Switch luci.model.uci to use ubus uci calls instead of driving libuci-lua directly. This prepares support for more advanced features such as per-session change isolation and configuration rollback on errors. Signed-off-by: Jo-Philipp Wich <jo@mein.io>

2018-03-11luci-base: fix parsing of ethers(5)Jo-Philipp Wich
The /etc/ethers file may contain any number of white space characters between the mac address and the IP/hostname field, so extend the pattern to allow for that. Man ethers(5) also states that the IP field may be a symbolic hostname, so test whether the name is an IP address or hostname before adding it to the hints structure. Fixes #1674.

2018-03-02luci-base: properly handle undefined IPv6 local-address informationJo-Philipp Wich
If IPv6 prefix assignment is disabled, the "local-address" structure might exist, but be empty which causes the adress formatting in the network model class to bail out. Verify the completeness of the "local-address" structure before using it in order to avoid runtime errors. Fixes #1657. Signed-off-by: Jo-Philipp Wich <jo@mein.io>

2018-02-16luci-base: do not assume a fixed host address in delegated prefix (#1484)Jo-Philipp Wich
OpenWrt/LEDE introduced the "local-address" field a while back to expose the effective local host address of the delegated prefix, so use that information instead of assuming `[prefix]:1`. Fixes #1484. Signed-off-by: Jo-Philipp Wich <jo@mein.io>
