R. Silva <gustavo@embeddedor.com> # Date: Tue Feb 11 10:00:37 2020 -0600 # # treewide: Replace zero-length arrays with flexible array member # # The current codebase makes use of the zero-length array language # extension to the C90 standard, but the preferred mechanism to declare # variable-length types such as these ones is a flexible array member[1][2], # introduced in C99: # # struct foo { # int stuff; # struct boo array[]; # }; # # By making use of the mechanism above, we will get a compiler warning # in case the flexible array does not occur last in the structure, which # will help us prevent some kind of undefined behavior bugs from being # unadvertenly introduced[3] to the codebase from now on. # # All these instances of code were found with the help of the following # Coccinelle script: # # @@ # identifier S, member, array; # type T1, T2; # @@ # # struct S { # ... # T1 member; # T2 array[ # - 0 # ]; # }; # # [1] https://gcc.gnu.org/onlinedocs/gcc/Zero-Length.html # [2] https://github.com/KSPP/linux/issues/21 # [3] commit 76497732932f ("cxgb3/l2t: Fix undefined behaviour") # # Signed-off-by: Gustavo A.
