This reverts commit 64602ad5b2.
Reverting this commit because the root cause of the issue was due to
a Broadcom SDK bug which caused VLAN-tagged packets to be tagged twice.
When packets were double-tagged, only one tag was getting stripped before
the packet was trapped to the CPU. However, the second tag was left behind,
which would cause the DHCP relay agent to ignore the packet. The bug has
since been fixed, so now all VLAN-tagged packets should properly have their
tag removed before being trapped to the CPU. Therefore the DHCP relay
agent should never encounter a VLAN-tagged packet.
* [DHCP relay]: Fix bug which could cause incorrect interface name association
* Add patches to series file and apply using stgit
* Update .gitignore in order to ignore downloaded and generated files
* Reorganize src/ subdirectories alphabetically in .gitignore
- Found a bug in v4.3.1-6 in which dhcrelay would not start if
passed an interface name with a length of 15 characters due
to truncated copy of interface name in common/lpf.c.
Bug was fixed in v4.3.2.
- v4.3.3-6 is the newest version we can build for Debian Jessie, as all
newer versions require newer versions of debhelper and
libbind-export-dev dependencies than are available for Jessie.
* [DHCP Relay]: Support new <DhcpRelays> minigraph tag; support multiple VLANs
* Don't start dhcrelay in quiet mode so as to get startup output in syslog
* Update sonic-cfggen tests to support new '<DhcpRelays>' tag
* <DhcpRelays> tag is only present for VLANs which require a DHCP relay agent -- only parse if present
* Don't attempt to configure a DHCP relay agent for VLANs without specified DHCP servers
* Modify to work with Taoyu's minigraph/DB changes (#942)
* Reduce number of DHCP servers in sonic-cfggen unit tests from 4 to 2
* Remove isc-dhcp-relay sample output file from sonic-cfggen test, as we no longer generate that file
* Update Option 82 isc-dhcp-relay patch to load all interface name-alias maps into memory once at start instead of calling sonic-cfggen on each packet we relay
* Remove executable permission from Jinja2 template
* Set max hop count to 1 so that DHCP relay will only relay packets with a hop count of zero
* Replace tabs with spaces
* Modify overlooked sonic-cfggen call, use Config DB instead of minigraph
* Also ensure > 1 VLAN requires a DHCP relay agent before outputting to template
* Generate port name-alias map file using sonic-cfggen and parse that in lieu of parsing port_config.ini directly
* No longer drop packets with hop count > 0; Instead, drop packets which already contain agent info
* [config]: Add SONIC_CONFIG_MAKE_JOBS
This config option allows user to specify -j value that will be passed
to each package build.
