* lua: avoid truncation of large numeric valuesAlin Nastac2020-03-151-1/+4
| | | | | | | | | | If the Lua number exceeds the maximum value representable by an unsigned 32bit integer, store it in an unsigned 64bit integer field instead. Signed-off-by: Alin Nastac <alin.nastac@gmail.com> [align code style, reword commit message] Signed-off-by: Jo-Philipp Wich <jo@mein.io>

* lua: workaround false positive dereference of null pointerPetr Štetiar2019-12-161-9/+10
| | | | | | | | | | | | | | | | | scan-build from clang-9 has reported following: ubus.c:837:16: warning: Access to field 'rnotify' results in a dereference of a null pointer (loaded from variable 'sub') sub->rnotify = luaL_ref(L, -2); Which is false positive as the lua_error() does a long jump and therefore never returns and this long jump probably confuses the static analyzer. So this patch workarounds this false positive by helping static analyzer by using common Lua idiom which is to return lua_error()'s return value.

* ubus/lua: pass notification name to callbackDirk Feytons2018-01-172-4/+6
| | | | | | | | | | | The callback function registered to be invoked when subscribing to a notification was only passed the notification data (if any) but not the name of the notification. This name is now passed as second argument to remain backwards compatible. The example subscriber.lua has also be updated. Signed-off-by: Dirk Feytons <dirk.feytons@gmail.com>

* ubus: Fix imbalance in lua stack push/pop of values.Karl Vogel2014-02-231-1/+5
| | | | | | | | | | | The lua getglobal and rawgeti both push a value onto the lua stack, but they weren't being removed by the ubus_method_handler function, thus corrupting the lua stack. In case the specified method wasn't a function, the stack was also corrupted as the method name remained on the stack. Signed-off-by: Karl Vogel <karl.vogel@gmail.com>
* lua: allow methods with no argumentsLuka Perkov2014-01-281-4/+12
| | | | | | | | | | | In C it is possible to have methods without arguments (UBUS_METHOD_NOARG). Enable support for the same calls in Lua too. This commit also fixes segfault which can be caused by passing non-table type where table is expected. The lua_gettablelen() function is called after we have made sure we are dealing with a table in the first place. Signed-off-by: Luka Perkov <luka@openwrt.org>
