[baseimage]: Improve password hashing for default user account (#1748)
* [slave.mk]: Fix displaying username and password in build summary
We display contents of DEFAULT_USERNAME and DEFAULT_PASSWORD, while
image can be build with USERNAME and/or PASSWORD given on make(1)
command line. For example:
$ make USERNAME=adm PASSWORD=mypass target/sonic-broadcom.bin
Fix by displaying USERNAME and PASSWORD variables in build summary.

* [baseimage]: Improve default user account handling
There are couple of issues with current implementation of default
user account management in baseimage:
1) It uses DES to encrypt accounts password. Furthermore this
effectively limits password length to 8 symbols, even if more
provided with PASSWORD or DEFAULT_PASSWORD from rules/config.
2) Salt value for password is same on all builds even with different
password increasing attack surface.
3) During the build process password passed as command line parameter
either as plain text (if given to make(1) as "make PASSWORD=...")
or DES encrypted (if given to build_debian.sh) can be seen by
non-build users using /proc/<pid>/cmdline file that has group and
world readable permissions.
Both 1) and 2) come from:
perl -e 'print crypt("$(PASSWORD)", "salt"),"\n"')"
that by defalt uses DES if salt does not have format $<id>$<salt>$,
where <id> is hashing function id. See crypt(3) for more details on
valid <id> values.
To address issues above we propose following changes:
1) Do not create password by hands (e.g. using perl snippet above):
put this job to chpasswd(8) which is aware about system wide
password hashing policy specified in /etc/login.defs with
ENCRYPT_METHOD (by default it is SHA512 for Debian 8).
2) Now chpasswd(8) will take care about proper salt value.
3) This has two steps:
3.1) For compatibility reasons accept USERNAME and PASSWORD as
make(1) parameters, but warn user that this is unsafe.
3.2) Use process environment to pass USERNAME and PASSWORD variables
from Makefile to build_debian.sh as more secure alternative to
passing via command line parameters: /proc/<pid>/environ
readable only by user running process or privileged users like
root.

## Create password for the default user

[baseimage]: Improve password hashing for default user account (#1748)
* [slave.mk]: Fix displaying username and password in build summary
We display contents of DEFAULT_USERNAME and DEFAULT_PASSWORD, while
image can be build with USERNAME and/or PASSWORD given on make(1)
command line. For example:
$ make USERNAME=adm PASSWORD=mypass target/sonic-broadcom.bin
Fix by displaying USERNAME and PASSWORD variables in build summary.
Signed-off-by: Sergey Popovich <sergey.popovich@ordnance.co>
* [baseimage]: Improve default user account handling
There are couple of issues with current implementation of default
user account management in baseimage:
1) It uses DES to encrypt accounts password. Furthermore this
effectively limits password length to 8 symbols, even if more
provided with PASSWORD or DEFAULT_PASSWORD from rules/config.
2) Salt value for password is same on all builds even with different
password increasing attack surface.
3) During the build process password passed as command line parameter
either as plain text (if given to make(1) as "make PASSWORD=...")
or DES encrypted (if given to build_debian.sh) can be seen by
non-build users using /proc/<pid>/cmdline file that has group and
world readable permissions.
Both 1) and 2) come from:
perl -e 'print crypt("$(PASSWORD)", "salt"),"\n"')"
that by defalt uses DES if salt does not have format $<id>$<salt>$,
where <id> is hashing function id. See crypt(3) for more details on
valid <id> values.
To address issues above we propose following changes:
1) Do not create password by hands (e.g. using perl snippet above):
put this job to chpasswd(8) which is aware about system wide
password hashing policy specified in /etc/login.defs with
ENCRYPT_METHOD (by default it is SHA512 for Debian 8).
2) Now chpasswd(8) will take care about proper salt value.
3) This has two steps:
3.1) For compatibility reasons accept USERNAME and PASSWORD as
make(1) parameters, but warn user that this is unsafe.
3.2) Use process environment to pass USERNAME and PASSWORD variables
from Makefile to build_debian.sh as more secure alternative to
passing via command line parameters: /proc/<pid>/environ
readable only by user running process or privileged users like
root.
Before change:
--------------
hash1
-----
# u='admin'
# p="$(LANG=C perl -e 'print crypt("YourPaSs", "salt"),"\n"')"
^^^^^^^^
8 symbols
# echo "$u:$p" | chpasswd -e
# getent shadow admin
admin:sazQDkwgZPfSk:17680:0:99999:7:::
^^^^^^^^^^^^^
Note the hash (DES encrypted password)
hash2
-----
# u='admin'
# p="$(LANG=C perl -e 'print crypt("YourPaSsWoRd", "salt"),"\n"')"
^^^^^^^^^^^^
12 symbols
# echo "$u:$p" | chpasswd -e
# getent shadow admin
admin:sazQDkwgZPfSk:17680:0:99999:7:::
^^^^^^^^^^^^^
Hash is the same as for "YourPaSs"
After change:
-------------
hash1
-----
# echo "admin:YourPaSs" | chpasswd
# getent shadow admin
admin:$6$1Nho1jHC$T8YwK58FYToXMFuetQta7/XouAAN2q1IzWC3bdIg86woAs6WuTg\
^^^^^^^^
Note salt here
ksLO3oyQInax/wNVq.N4de6dyWZDsCAvsZ1:17681:0:99999:7:::
hash2
-----
# echo "admin:YourPaSs" | chpasswd
# getent shadow admin
admin:$6$yKU5g7BO$kdT02Z1wHXhr1VCniKkZbLaMPZXK0WSSVGhSLGrNhsrsVxCJ.D9\
^^^^^^^^
Here salt completely different from case above
plFpd8ksGNpw/Vb92hvgYyCL2i5cfI8QEY/:17681:0:99999:7:::
Since salt is different hashes for same password different too.
hash1
-----
# LANG=C perl -e 'print crypt("YourPaSs", "\$6\$salt\$"),"\n"'
^^^^^
We want SHA512 hash
$6$salt$qkwPvXqUeGpexO1vatnIQFAreOTXs6rnDX.OI.Sz2rcy51JrO8dFc9aGv82bB\
yd2ELrIMJ.FQLNjgSD0nNha7/
hash2
-----
# LANG=C perl -e 'print crypt("YourPaSsWoRd", "\$6\$salt\$"),"\n"'
$6$salt$1JVndGzyy/dj7PaXo6hNcttlQoZe23ob8GWYWxVGEiGOlh6sofbaIvwl6Ho7N\
kYDI8zwRumRwga/A29nHm4mZ1
Now with same "salt" and $<id>$, and same 8 symbol prefix in password, but
different password length we have different hashes.

[baseimage]: install ndisc6 package (#3344)
ndisc6 gathers a few diagnostic tools for IPv6 networks including:
- ndisc6, which performs ICMPv6 Neighbor Discovery in userland,
- rdisc6, which performs ICMPv6 Router Discovery in userland,
- rltraceroute6, a UDP/ICMP IPv6 implementation of traceroute,
- tcptraceroute6, a TCP/IPv6-based traceroute implementation,
- tcpspray6, a TCP/IP Discard/Echo bandwidth meter,
- addrinfo, easy script interface for hostname and address resolution,
- dnssort, DNS sorting script.

Fix potential blackholing/looping traffic when link-local was used and refresh ipv6 neighbor to avoid CPU hit (#1904)
* Fix potential blackholing/looping traffic and refresh ipv6 neighbor to avoid CPU hit
In case ipv6 global addresses were configured on L3 interfaces and used for peering,
and routing protocol was using link-local addresses on the same interfaces as prefered nexthops,
the link-local addresses could be aged out after a while due to no activities towards the link-local
addresses themselves. And when we receive new routes with the link-local nexthops, SONiC won't insert
them to the HW, and thus cause looping or blackholing traffic.
Global ipv6 addresses on L3 interfaces between switches are refreshed by BGP keeplive and other messages.
On server facing side, traffic may hit fowarding plane only, and no refresh for the ipv6 neighbor entries regularly.
This could age-out the linux kernel ipv6 neighbor entries, and HW neighbor table entries could be removed,
and thus traffic going to those neighbors would hit CPU, and cause traffic drop and temperary CPU high load.
Also, if link-local addresses were not learned, we may not get them at all later.
It is intended to fix all above issues.
Changes:
Add ndisc6 package in swss docker and use it for ipv6 ndp ping to update the neighbors' state on Vlan interfaces
Change the default ipv6 neighbor reachable timer to 30mins
Add periodical ipv6 multicast ping to ff02::11 to get/refresh link-local neighbor info.
* Fix review comments:
Add PORTCHANNEL_INTERFACE interface for ipv6 multicast ping
format issue
* Combine regular L3 interface and portchannel interface for looping
* Add ndisc6 package to vs docker
