- What I did
Configure sshd to close all SSH connetions after 15 minutes of inactivity.
- How I did it
Set ClientAliveInterval to 900 (900 seconds = 15 minutes) and ClientAliveCountMax to 0
in /etc/ssh/sshd_config using augtool in build_debian.sh. In the process, I refactored the existing augtool command for sshd_config so as to add comments and empty lines to file for readability.
- How to verify it
Log into device via management port. Wait 15 minutes without sending a keystroke -- you should be automatically logged out.
* Added debug symbols to many debug dockers.
* For debug images *only*:
1) Archive source files into debug image
2) Archived source is copied into /src
3) Created an empty dir /debug
4) Mount both /src as ro & /debug as rw into every docker
5) Login banner will give some details on /src & /debug
6) Devs can copy core file into /debug and view it from inside a container.
7) Dev may create all gdb logs and other data directly into /debug.
* Dropped redundant REDIS_TOOLS per review comments.
* Added debug symbols to frr package and hence FRR based BGP docker.
* 1) Moved dbg_files.sh to scripts/
2) Src directories to archive are now collected from individual Makefiles.
3) Added few more debug symbols
4) Added few more debug dockers.
Here after no more changes except per review comments.
To debug:
Install required version of debug image in Switch or VM.
Copy core file into /debug of host
Get into Docker
gdb /usr/bin/<daemon> -c /debug/<your core file>
set directory /src/... <-- inside gdb to get the source
For non-in-depth debugging:
Download corresponding debug Docker image (docker-...-dbg.gz) to your VM
Load the image
Run image with entrypoint as 'bash' with dir containing core mapped in.
Run gdb on the core.
* [submodule] update sonic-linux-kernel
* update linux kernel version
* Fix many version strings
* update mellanox components (built with new kernel)
* [mlnx] add make files for SDK WJH libs
* Update arista driver submodule (#8)
Make the debian packaging point to a newer kernel version.
- What I did
Currently when the system is under memory pressure, the OOM killer kicks in and kills a rogue process. Killing a rogue process can cause the device to be un-healthy leading to blackholing of the traffic.
To avoid this, configure the OOM to do a kernel panic which will cause the device to reboot and come back up healthy.
- How I did it
Added the sysctl variable panic_on_oom and set the value to 2.
Setting it to 2 will ensure OOM killer to always do a kernel panic.
- Add ebtables package, and install some filter rules:
1. ebtables -A FORWARD -d BGA -j DROP
2. ebtables -A FORWARD -p ARP -j DROP
Basically, we let the ARP packets in the VLAN being forwarded by the ASIC,
kernel gets a copy of these ARP packets and the forwarding from Kenerl gets
dropped. So there is always only one copy of ARP/response in the VLAN.

When rebooting without the platform_reboot plugin, systemd takes a few
minutes to properly shutdown. It's blocking on some docker cleanup
operation.
As described by https://github.com/docker/for-linux/issues/421 there
is a race between docker.service and containerd.service.
docker needs containerd to properly stop the containers.

* 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
some platform drivers install blacklist.conf in /etc/modprobe.d.
Those configuration should be proprogated into initramfs to avoid
loading those blacklisted driver.
* [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>$,
where <id> is hashing function id. See crypt(3) for more details on
valid <id> values.
To address issues above we propose following changes:
1) Do not create password by hands (e.g. using perl snippet above):
put this job to chpasswd(8) which is aware about system wide
password hashing policy specified in /etc/login.defs with
ENCRYPT_METHOD (by default it is SHA512 for Debian 8).
2) Now chpasswd(8) will take care about proper salt value.
3) This has two steps:
3.1) For compatibility reasons accept USERNAME and PASSWORD as
make(1) parameters, but warn user that this is unsafe.
3.2) Use process environment to pass USERNAME and PASSWORD variables
from Makefile to build_debian.sh as more secure alternative to
passing via command line parameters: /proc/<pid>/environ
readable only by user running process or privileged users like
root.
Before change:
--------------
hash1
-----
# u='admin'
# p="$(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/

Now with same "salt" and $<id>$, and same 8 symbol prefix in password, but
different password length we have different hashes.

* [core dump] pass unix time to coredump-compress script
Currently we only have program name (e.g. bgpd) and PID in the core file

Passing the unix time to coredump-compress so it could also add time to
the core file name.

* [quagga] enable core dump for bgpd and zebra
bgpd and zebra downgrade their privilege shortly after started. For that
sysctrl kernel.suid_dumpable needs to be set to 2, so that they can dump
core.
Note that fs.suid_dumpable SHOULD NOT be set to 1. Which will bypass all
system security.

The reason is that /etc/network/interfaces file is in base image. After booting,
docker-swss is not ready and thus the empty VLAN interfaces cannot be created
when the brctl is pointing to the binary inside the swss docker.

This change disables DAD (IPv6's Duplicate Address Detection). DAD
protects against IP address conflicts. The way it works is that after
an address is added to an interface, the operating system uses the
Neighbor Discovery Protocol to check if any other host on the network
has the same address. If it finds a neighbor with the same address,
the address is removed from the interface.
The problem here is that the time waiting for DAD to be done is fairly
long and because that we set the host interface operating status to be
down at first, the port cannot exchange the Neighbor Discovery Protocol
and DAD will time out. The host interface is only brought up after we
have received the port admin status up notification from the kernel,
which happens only after the DAD is done or times out. This makes the
whole host interfaces bringing up procedure very slow.
This the DAD is disabled. When it is disabled, addresses are immediately
usable. Without DAD, we need to make sure that the IPv6 addresses don't
have conflicts. For now, we have two IPv6 addresses. One is assigned
manually, which prevents conflicts at first. Another one is the IPv6
link-local address. It is derived from the MAC address and thus all the
link-local addresses are the same on one box. Because link-local addresses
are not used, it will not trigger issues even if they are the same.
