2 years agounittest: gcc-11 errors for clib_strcpy, clib_strstr, clib_strcat, and clib_strncat 30/34330/5
Steven Luong [Wed, 3 Nov 2021 22:33:21 +0000 (15:33 -0700)]
unittest: gcc-11 errors for clib_strcpy, clib_strstr, clib_strcat, and clib_strncat

There are 3 versions of the string functions. For example, for strcpy,
they are
1. strcpy(dst, src) -- the legacy unsafe version
2. strcpy_s(dst, dmax, src) -- C11 safeC version which has an addition argument
named dmax.
3. clib_strcpy(dst,src) -- clib version to enable legacy code that uses strcpy
to make use of strcpy_s without adding the additional argument, dmax, which is
required by the C11 safeC version.

The implementation for the clib version is to artificially provide dmax to
strcpy_s. In this case, it uses 4096 which assumes that if the legacy code
works without blowing up, it is likely to work with the clib version without
problem.

gcc-11 is getting smarter by checking if dmax is within the object's boundary.
When the object is declared as static array, it will flag a warning/error
if dmax is out of bound for the object since the real size of dst can be
determined at compile time.

There is no way to find the real size of dst if the object is dynamically
allocated at compile time. For this reason, we simply can't provide support
for the clib version of the function anymore. If any code is using the clib
version, the choice is to migrate to the safeC version.

tcp: fix: TCP timewait port reuse rfc compliance

This patch provides a fix for early-kill of timewait sockets that is based on
rfc's 1122, 6191.

The following commits provided a solution for port re-use. However, they
are not fully compliant with rfc 1122 4.2.2.13 ( Closing a connection )
and rfc 6191 (Reducing the TIME-WAIT State Using TCP Timestamps)

commit b092b77cf238ba ("tcp: Enable TCP timewait port use") introduced
a significant improvement by enabling TCP timewait port re-use.

commit ee1cb469b2dd ("tcp: fix port reuse with multiple listeners") fixed
usage of the wrong value for connection_index when searching for a
listener, by storing the state in tcp.flags.

Implementation details:
When a SYN is received during time-wait state, the code
checks whether all the requirements for accepting the SYN packet are
met. If they aren't, the SYN can't be accepted and the packet is dropped,
otherwise, connection is deleted and a new connection with same port
is opened.
