Upgrade kernel (rt) to version kernel-3.10.0-957.21.3.el7

Security Fix(es):
(CVE-2019-11477)-
An integer overflow flaw was found in the way
the Linux kernel's networking subsystem processed
TCP Selective Acknowledgment (SACK) segments.
While processing SACK segments,
the Linux kernel's socket buffer (SKB) data structure
becomes fragmented. Each fragment is about TCP
maximum segment size (MSS) bytes.
To efficiently process SACK blocks, the Linux kernel merges
multiple fragmented SKBs into one, potentially overflowing
the variable holding the number of segments.
A remote attacker could use this flaw to crash the Linux kernel
by sending a crafted sequence of SACK segments on a TCP
connection with small value of TCP MSS,
resulting in a denial of service (DoS).

(CVE-2019-11478)-
Kernel: tcp: excessive resource consumption while processing SACK blocks
allows remote denial of service.

(CVE-2019-11479)-
Kernel: tcp: excessive resource consumption for TCP connections with low MSS
allows remote denial of service.
