2017-12-12libusbgx: fix: Disallow creating function with empty instance nameKrzysztof Opasiak1-1/+1
USB function should have both type and instance name. Mistakenly it was possible to create function with empty instance name. This may lead to situations like FunctionFS device name identified by "" or some misleading debug messages from TCM like: tcm: Activating Additionaly trying to execute usbg_init() after creating such a function fails with -3 USBG_ERROR_INVALID_PARAM because it checks if instance name is not empty. To avoid this let's add a check in usbg_create_function() that instance name should have at least one character. Signed-off-by: Krzysztof Opasiak <k.opasiak@samsung.com>

2017-12-12libusbgx: Make usbg_rm_config() aware of OS descriptorsKrzysztof Opasiak1-2/+10
Since we added support for OS descriptors we allowed user to create a link in gadget's os_desc directory to choose one of available configurations. This link prevents config from being removed. This makes our rm funcitons stop working with the recursive option. To fix this, let's make them OS desc aware and remove this link before trying to remove configuration if recurse option is set.

2017-12-11libusbgx: Do not write null terminator when using usbg_write_string()Stefan Agner1-1/+1

2017-11-20libusbgx: fix: Check fclose() return codeKrzysztof Opasiak1-7/+11
According to man fclose: "The fclose() function may also fail and set errno for any of the errors specified for the routines close(2), write(2) or fflush(3)." So if libc decides to cache our write till closing fd we may miss the error if we ignore value returned from fclose(). This fixes issue #12 (github).

2017-03-03libusbgx: Fix meaning of HAS_LIBCONFIG and HAS_GADGET_SCHEMESKrzysztof Opasiak10-24/+32
We have two configure options related to libconfig: 1) --disable-gadget-schemes 2) --without-libconfig Option #1 means that libusbgx itself should be compiled without gadget schemes support. Option #2 means that everything what requires libconfig should be turned off. So option #2 is wider than #1 as libconfig us used also in our testing program. To fix this meaning let's use HAS_GADGET_SCHEMES inside library source code to determine if we should use libconfig or not and HAS_LIBCONFIG inside our tests source code.

2017-03-03libusbgx: Fix compilation without libconfigKrzysztof Opasiak7-216/+296
After refactorization we lost ability to build libusbgx without libconfig. Let's restore this. Basic concept is that the whole code related to libconfig usage should be under #ifdef or compiled only if libconfig support is enabled. To prevent future problems of that kind, let's create a header which is included when compiling without libconfig. Inside it we like: struct s { .import = usbg_get_config_node_int, .export = usbg_set_config_node_int, }; are still valid, but all tries to call this functions directly end up in compilation error. This helps us identify all pieces of code which should be placed under suitable #ifdef.

2017-03-03libusbgx: common: Use fread() instead of fgets()Krzysztof Opasiak3-40/+38
