[docker_image_ctl.j2] Share UTS namespace with host OS (#4169)
Instead of updating hostname manualy on Config DB hostname change,
simply share containers UTS namespace with host OS.
Ideally, instead of setting `--uts=host` for every container in SONiC,
this setting can be set per container if feature requires.
One behaviour change is introduced in this commit, when `--privileged`
or `--cap-add=CAP_SYS_ADMIN` and `--uts=host` are combined, container
has privilege to change host OS and every other container hostname.
Such privilege should be fixed by limiting containers capabilities.

[hostcfgd] avoid in place editing config file contents (#3904)
In place editing (sed -i) seems having some issues with filesystem
interaction. It could leave 0 size file or corrupted file behind.

It would be safer to sed the file contents into a new file and switch
new file with the old file.

Fix to ensure that tacacs servers are ordered (reverse) by priority in pam.d's config. (#3322)
Present: Servers are listed in the same order as in redis-db
Fix: Save the sort o/p, hence use sorted list to write into pam.d's conf.
     As well convert priority to integer for use by sort.

6d7ecc426c [hostcfgd] -- Fix the default for failthrough as false.
This implies that by default, if TACACS is configured properly and it reported auth_err, then don't try fail through to traditional unix authentication through /etc/passwd.

If this failthrough is intended, make it explicit through "sudo config aaa authentication failthrough enable"

Removed an unused variable "aaa.fallback"

Tested manually. Note the presence of 'auth_err=die' in all cases except when failthrough is explicitly enabled.

fa7c46611e [hostcfgd]: Promote logs for update-notifications-from-DB from DEBUG to INFO (#2576)
* Add a log message for each notification of add/del TACACS server.

Signed-off-by: Renuka Manavalan <remanava@microsoft.com>

* Moved another syslog message from DEBUG to INFO to be able to see those notifications.

All these changes are to help with a one-time-seen-bug, that hostcfgd did not act upon changes to redis for TACACS servers. We could not repro the bug.
