I have managed to create a sample of all that code, although I find the #define list_entry_const somewhat difficult to deconstruct. However, with a valid name in the file_info entry it works fine. I can only assume that somewhere in the actual code that you are running there is some corruption of your data, or a pointer is not set up correctly.
I also could not find the TRACE macro in Windows.
I am really puzzled by how difficult it seem to be to explain how the value of that .directory was initialized. Where its value came from. How it was created.
Obviously, whatever created the value did not follow the C convention of terminating it with a nul - most likely because it doesn't have a C origin. Fair enough. But why is it so difficult to show how the .directory value was obtained?
As it now stands, it is like complaining "This variable should have av value between 0 and 100, but it is above 100. Why???" If you can't figure that out yourself, you must reveal how you calculate it, you cannot simply tell us how you use it, after it has gotten that out-of-range value-
Your directory string is another out-of-range value. How you use it, after it got this illegal value is of no interest. The important thing is how it got that value, not how you later use it. Like if you ask "Why does my value exceed 100?" Noone can tell unless you tell how you got or calculated that value. String values are no different: If they have an illegal value, such as not being nul-terminated in contexts where that is expected, the problem is in the source, not in the use of the value.
If it is as difficult as it seems to trace the source, identify where that directory sting came from, then you should not expect others to be able to help you. "I have an illegal value, but I can't tell where it came from - why is it not legal?" - noone can give you a reasonable answer to that.
So come on, tell us how the .directory value was obtained/created! Until you do that, you cannot expect any useful help from other forum members
is not ok, of course. INIT_LIST_HEAD, list_for_each and list_entry_const are Linux functions. logdir functions I could not reproduced in a test app or write here because has many dependencies ... and to be everything more complicated, all this code is written in a recursive function .... is quite difficult to reproduced this situation in a test app ... I am trying to explore logdir function to see what I find there ...
