## USAGE:
[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.

[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.

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
