R. Silva <gustavo@embeddedor.com> # Date: Fri Feb 21 09:32:33 2020 -0600 # # firmware: google: vpd: Replace zero-length array 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 # inadvertently introduced[3] to the codebase from now on. # # Also, notice that, dynamic memory allocations won't be affected by # this change: # # "Flexible array members have incomplete type, and so the sizeof operator # may not be applied. As a quirk of the original implementation of # zero-length arrays, sizeof evaluates to zero."[1] # # This issue was found with the help of Coccinelle. # # [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.
