If anyone has any objections, please let me know. ------------------ From: Malaya Kumar Rout [ Upstream commit 0bebfaa39deadec21638f6fba553eae12627a26d ] In msg_alloc_iov(), when calloc() fails for an individual iov_base allocation, the error path frees all previously allocated iov_base entries but fails to free the iov array itself that was allocated with calloc() at the beginning of the function. This results in a memory leak of the iov array. Add free(iov) in the unwind_iov error path to ensure proper cleanup of all allocated memory.
