There's a build race condition with other packages which sometimes results in:
Package libnetsnmp is missing dependencies for the following libraries:
libpci.so.3
Using an external toolchain, it was discovered that net-snmp would
link with the Perl library (-lperl) from the host rather than from the
target.
Since we do not provide Perl as a dependency to net-snmp, the solution
is to disable support for it.
Fixes issue #8217.

Disable PCRE process searching to avoid linking against libprce, which
would cause the build to fail due to a missing dependency. With the
--without-pcre switch, build fails due to an undefined reference, so do
it via CONFIGURE_VARS instead.

This enables the table `inetNetToMediaTable` from `ip-mib`, which implements
the `ipNetToPhysicalTable`. The former one is already enabled with the current
configuraiton, but it has been deprecatd by the IP version-neutral
`ipNetToMediaTable`, which also supports IPv6 entries [1]. It also disables all
other submodules from this MIB to keep the footprint small.

Commit ae5ee6ba6c added support for inbound
firewall rule support but some corner cases were not covered.
In case net-snmp is started and the network interface is already up
the procd firewall rule is created but not applied by fw3 as
service_started calling procd_set_config_changed firewall was missing.
When stopping net-snmp clean up the net-snmp inbound firewall rules in
iptables by calling procd_set_config_changed firewall in stop_service
which will trigger fw3 to remove the inbound firewall rules.

It seems that UCI can't handle duplicate section names in a single
config file, even if they use different types. After the previous
commit, running `uci export` results in the following error:
uci: Parse error (section of different type overwrites prior section with same name) at line 17, byte 23
Append a 6 to the com2sec6 section names to solve this.

A lot of autoconf-based scripts expect --with-foo-dir=$(STAGING_DIR)/usr
and break if they can't find bin/foo-config as a child of that path.
Putting things in $(STAGING_DIR)/host/bin seems to be suboptimal; I
could change the install path but there's no saying what that would
break.

Add UCI section general which holds the uci parameter network defining on
which interface(s) the snmp agent is reachable for inbound snmp requests
in case the firewall zone does not allow INPUT traffic by default.
For the different zones to which the different interfaces belong firewall
procd input rules are created making the snmp agent reachable on udp port

According to the snmpd.conf man page, the engineID of an snmp agent
should be consistent through time. However, it seems that the engineID
changes every reboot. Add options to configure how the engineID is
generated. The default setting generates it based on the MAC address of
the eth0 interface.

Instead of causing nondeterministing conditional compilation depending on
whether libnl-core happens to be present or not, fixup the net-snmp package
to link against libnl-tiny which is present by default on the majority of
systems.
In order to successfully build against libnl-tiny, a number of things had
to be fixed in both the upstream configure and the outer Makefile:
- Add a patch which fixes the upstream configure macros to properly handle
cases where the cache variables for nl_connect() and netlink.h tests are
predefined. Without this patch, all subsequent link tests in configure
will fail, causing the build system to assume functions like opendir() or
readdir() to be missing, leading to build failures later on due to
conflicting redefinitions of structures and function prototypes
- In the same patch, stop probing the host systems /usr/include/libnl-3 if
ac_cv_header_netlink_netlink_h is given. This brings the proprietary
configure bits in line with the behaviour expected from autoconfig in a
cross compile setting
- Explicitely request nl support by passing the --with-nl flag to configure
- Pass the required cache variables to skip the broken tests for
nl_connect() and netlink.h
- Amend TARGET_CPPFLAGS to let net-snmp's build system discover nl-tiny's
netlink/netlink.h and netlink/socket.h
- Enable the autoreconf fixup to regenerate the broken shipped configure
from patched macros
- Adjust the depends to unconditionally require libnl-tiny

When applying wireless configuration changes, the ifindex of the
wireless interface(s) change. While snmpd picks up the new interfaces
with the correct index, it does not remove the old ones:
IF-MIB::ifName.23 = STRING: wlan0
IF-MIB::ifName.24 = STRING: wlan1
IF-MIB::ifName.25 = STRING: wlan0
IF-MIB::ifName.26 = STRING: wlan1
This causes problems for monitoring tools that use ifName (or ifDesc) as
interface reference. Add a trigger that reloads snmpd on interface
up/down events so that it will no longer have the old interfaces.
Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>
When an ifindex for an interface changes, some monitoring tools can no
longer find the interface and send alerts. Monitor all network
interfaces via the procd netdev parameter, so that
/etc/init.d/snmpd reload will restart snmpd if any ifindex changed.
