https://bugzilla.kernel.org/show_bug.cgi?id=104601 Bug ID: 104601 Summary: Description of getname-related syscalls wrong Product: Documentation Version: unspecified Hardware: All OS: Linux Status: NEW Severity: high Priority: P1 Component: man-pages Assignee: documentation_man-pages@xxxxxxxxxxxxxxxxxxxx Reporter: mattator@xxxxxxxxx Regression: No For instance, if I look at the getsockname man page on ubuntu 15.04: === getsockname() returns the current address to which the socket sockfd is bound, in the buffer pointed to by addr. The addrlen argument should be initialized to indicate the amount of space (in bytes) pointed to by addr. On return it contains the actual size of the socket address. The returned address is truncated if the buffer provided is too small; in this case, addrlen will return a value greater than was supplied to the call. === I've looked at some getname function for different protocols in the 4.3 and 3.14 kernels and the addrlen parameter was never considered as an input or the returned sockaddr* truncated. This was the cause of a stack smashing in a userspace application I use and possibly many others so I ranked it high.
