New Revision: 305086
URL: https://svnweb.freebsd.org/changeset/base/305086
Log:
Fix warnings in telnet about invalid constant conversions, e.g.:
contrib/telnet/telnet/commands.c:2914:13: error: implicit conversion
from 'int' to 'char' changes value from 137 to -119
[-Werror,-Wconstant-conversion]
*lsrp++ = IPOPT_SSRR;
~ ^~~~~~~~~~
/usr/include/netinet/ip.h:152:21: note: expanded from macro 'IPOPT_SSRR'
#define IPOPT_SSRR 137 /* strict source route */
^~~
contrib/telnet/telnet/commands.c:2916:13: error: implicit conversion
from 'int' to 'char' changes value from 131 to -125
[-Werror,-Wconstant-conversion]
*lsrp++ = IPOPT_LSRR;
~ ^~~~~~~~~~
/usr/include/netinet/ip.h:148:21: note: expanded from macro 'IPOPT_LSRR'
#define IPOPT_LSRR 131 /* loose source route */
^~~
Use unsigned char buffers instead.
