commit d8106bbb5348591968722e14fe4ee4b81e7902aa

Fix issue found by Coverity
This isn't something that can actually be triggered. The port parameter is
always NULL, so just drop the parameter and the call to strcat().
Error: STRING_OVERFLOW (CWE-120):
keyutils-1.5.10/key.dns_resolver.c:388: fixed_size_dest: You might overrun the 55-character fixed-size string "buf" by copying "port" without checking the length.
keyutils-1.5.10/key.dns_resolver.c:388: parameter_as_source: Note: This defect has an elevated risk because the source argument is a parameter of the current function.

commit 75e7568dc516db698093b33ea273e1b4a30b70be
Author: David Howells <dhowells@redhat.com>
Date: Tue, 14 Apr 2020 16:07:26 +0100
dns: Apply a default TTL to records obtained from getaddrinfo()
Address records obtained from getaddrinfo() don't come with any TTL
information, even if they're obtained from the DNS, with the result that
key.dns_resolver upcall program doesn't set an expiry time on dns_resolver
records unless they include a component obtained directly from the DNS,
such as an SRV or AFSDB record.
Fix this to apply a default TTL of 10mins in the event that we haven't got
one. This can be configured in /etc/keyutils/key.dns_resolver.conf by
adding the line:
default_ttl = <number-of-seconds>
to the file.

.SH DESCRIPTION
This program is invoked by request\-key on behalf of the kernel when kernel
services (such as NFS, CIFS and AFS) want to perform a hostname lookup and the
kernel does not have the key cached. It is not ordinarily intended to be
called directly.
.P
-It can be called in debugging mode to test its functionality by passing a
-\fB\-D\fR flag on the command line. For this to work, the key description and
-the callout information must be supplied. Verbosity can be increased by
-supplying one or more \fB\-v\fR flags.
+There program has internal parameters that can be changed with a configuration
+file (see key.dns_resolver.conf(5) for more information). The default
+configuration file is in /etc, but this can be overridden with the \fB-c\fR
+flag.
+.P
+The program can be called in debugging mode to test its functionality by
+passing a \fB\-D\fR or \fB\--debug\fR flag on the command line. For this to
+work, the key description and the callout information must be supplied.
+Verbosity can be increased by supplying one or more \fB\-v\fR flags.
+.P
+The program may also be called with \fB--dump-config\fR to show the values that
+configurable parameters will have after parsing the config file.

All errors will be logged to the syslog.

+.TH KEY.DNS_RESOLVER.CONF 5 "18 May 2020" Linux "Linux Key Management Utilities"
+.SH NAME
+key.dns_resolver.conf \- Kernel DNS resolver config
+.SH DESCRIPTION
+This file is used by the key.dns_resolver(5) program to set parameters.
+Unless otherwise overridden with the \fB\-c\fR flag, the program reads:
+.IP
+/etc/key.dns_resolver.conf
+.P
+Configuration options are given in \fBkey[=value]\fR form, where \fBvalue\fR is
+optional. If present, the value may be surrounded by a pair of single ('') or
+double quotes ("") which will be stripped off. The special characters in the
+value may be escaped with a backslash to turn them into ordinary characters.
+.P
+Lines beginning with a '#' are considered comments and ignored. A '#' symbol
+anywhere after the '=' makes the rest of the line into a comment unless the '#'
+is inside a quoted section or is escaped.
+.P
+Leading and trailing spaces and spaces around the '=' symbol will be stripped
+off.
+.P
+Available options include:
+.TP
+.B default_ttl=<number>
+The number of seconds to set as the expiration on a cached record. This will
+be overridden if the program manages to retrieve TTL information along with
+the addresses (if, for example, it accesses the DNS directly). The default is
+5 seconds. The value must be in the range 1 to INT_MAX.
+.P
+The file can also include comments beginning with a '#' character unless
+otherwise suppressed by being inside a quoted value or being escaped with a
+backslash.
