docs: fix simple typo, conspicuosly -> conspicuously

2021-04-10T11:43:12Z

There is a small typo in plugins-root/check_icmp.c. Should read `conspicuously` rather than `conspicuosly`.

Use size_t instead of int when calling sysctl(3).

Otherwise, it writes sizeof(size_t) bytes to &oldlen, smashing the stack.

check_icmp: Do not overwrite -4,-6 on lookup

2018-12-10T14:39:13Z

In case we needed to do a lookup, we previously overwrote the address_family to IPv6, even if we supplied -4 as a cmd line argument. This commit should ensure the cmd line argument is always followed. Signed-off-by: Jacob Hansen

check_icmp: emit error if multiple protocol version

2018-12-10T14:39:13Z

As we do not support checking both IPv4 and IPv6 hosts in one execution we emit an error if multiple protocol versions are defined in the cmd line args. Signed-off-by: Jacob Hansen

check_icmp: move opts string into a variable

2018-12-10T14:39:13Z

This commit moves the opts string into a variable as it is now used twice. Signed-off-by: Jacob Hansen

check_icmp: Correctly set address_family on lookup

2018-12-07T09:51:21Z

If a hostname is supplied instead of an IP address, the automatic address family detection would fail to correctly set the IP protocol version (it would always be IPv6). We now supply AF_UNSPEC to getaddrinfo, which should then return the correct address family in the result. Signed-off-by: Jacob Hansen

check_icmp: removed outcommented code

check_icmp: process protocol version args first

2018-12-07T09:51:21Z

Detection of protocol version is in the previous patch implemented in the add_target() function, which is called when adding the -H command line argument. That means that if a protocal version argument (-4, -6) is added after the -H then the protocol version might be incorrectly set. This patch ensures that we first process the protocol version arguments, and then we process the rest of the arguments. Signed-off-by: Jacob Hansen

check_icmp: Automatically detect IP protocol

2018-12-07T09:51:21Z

This patch automatically detects whether the protocol version is IPv4 or IPv6 All credits to: https://github.com/ghciv6 Signed-off-by: Jacob Hansen
