src/usr.bin/ftp [netbsd-10]: cmdtab.c extern.h fetch.c ftp.1 main.c
ssl.c util.c version.h
Log Message:
Pull up following revision(s) (requested by lukem in ticket #170):
usr.bin/ftp/ssl.c: revision 1.13
usr.bin/ftp/fetch.c: revision 1.236
usr.bin/ftp/util.c: revision 1.166
usr.bin/ftp/main.c: revision 1.129
usr.bin/ftp/extern.h: revision 1.83
usr.bin/ftp/ftp.1: revision 1.148
usr.bin/ftp/cmdtab.c: revision 1.53
usr.bin/ftp/version.h: revision 1.96
Add option sslnoverify to control validation of SSL certificates.
Add netrc processing to fetch-mode (URL on command line) to enable options and
autologin
via netrc.
Fix SSL cleanup in some error paths.
Certificate validation is now enabled by default. Set FTPSSLNOVERIFY=1 in
environment
or configure a corresponding init macro via netrc to not validate certs
(required if
you haven't installed a required CA certificate for OpenSSL).
Discussed with lukem@ on icb.
