2023-09-23Remove check for RETSIGTYPE in autoconf stuffRincewindsHat1-1/+1
autoupdate tells me, that since C89 I can safely assume RETSIGTYPE is void. Therefore to simplify things I removed the corresponding configure.ac line and replaced all mentions of RETSIGTYPE with void.

* lib/utils_base.c * plugins/check_curl.c * plugins-root/check_dhcp.c Removed a line which theoretically can not do anything, but there was comment which indicated something else. Still trying this though.

Also added handling of name_prev in np_add_parameter and np_delete_parameter. This make calling the np_delete_parameter function easier, because it requires the previous element as second argument.

2021-11-17check_snmp: fix performance thresholds when using multiple oidsSven Nierlein2-1/+2
when using check_snmp with multiple oids it simply printed the unparsed content from -w/-c into the thresholds for each oid. So each oid contained the hole -w from all oids. ./check_snmp ... -o iso.3.6.1.2.1.25.1.3.0,iso.3.6.1.2.1.25.1.5.0 -w '1,2' -c '3,4' before: SNMP ... | HOST-RESOURCES-MIB::hrSystemInitialLoadDevice.0=393216;1,2;3,4 HOST-RESOURCES-MIB::hrSystemNumUsers.0=24;1,2;3,4 after: SNMP ... | HOST-RESOURCES-MIB::hrSystemInitialLoadDevice.0=393216;1;3 HOST-RESOURCES-MIB::hrSystemNumUsers.0=24;2;4 This also applies to fixed thresholds since check_snmp translates negative infinities from: '~:-1' to '@-1:~'

2019-02-15check_by_ssh: fix child process leak on timeoutsSven Nierlein4-25/+54
When check_by_ssh runs into a timeout it simply exits keeping all child processes running. Simply adopting the kill loop from runcmd_timeout_alarm_handler() fixes this. Signed-off-by: Sven Nierlein <sven@nierlein.de>

2014-10-06Revert "Make use of xasprintf instead of asprintf"Holger Weiss1-3/+3
This reverts commit a143739ed286cf9ae003792dbb1ce26ce43f3312. Our current setup doesn't allow lib/*.c files to call functions defined in plugins/utils.[ch].

--- Closes #1278
2014-07-30lib/utils_base.c: if asprintf fails, string is undefinedRicardo Maraschini1-5/+10
if asprintf fails, string content becomes invalid. we need to check if it ran OK by checking the returned value. in case of fail, asprintf returns -1, otherwise the number of writen bytes is returned. also, on ubuntu 13.10 i've receiving a lot of warnings: "warning: ignoring return value of ‘asprintf’" this patches fixes some of them Signed-off-by: Ricardo Maraschini <ricardo.maraschini@gmail.com> --- Closes #1227
2014-07-06check_icmp/check_dhcp: disable check, if we are rootJan Wagner2-16/+0
As it is possible to use capabilities(7) on linux or solaris privileges for example, it is not necessary in all cases to have those binaries making use of setuid.

2014-06-21Add UID to state retention file pathHolger Weiss2-3/+9
Add the UID of the invoking user to the state retention file path. This helps solving permission issues when different users run the same plugin.
2014-06-18lib/parse_ini.c: Print proper read error messageHolger Weiss1-1/+2
Print a useful error message if opening the configuration file fails.
2014-06-18lib/parse_ini.c: Drop privileges for reading fileHolger Weiss1-0/+10
Read the configuration file with privileges temporarily dropped if the code is used by a setuid plugin.
2014-06-18lib/parse_ini.c: Add newline to die() callsHolger Weiss1-2/+2
Our die() function doesn't append a newline character to the message.
2014-06-18lib/parse_ini.c: Cosmetic changeHolger Weiss1-4/+1
Replace an "if" with the ternary operator.
2014-06-18lib/parse_ini.c: Search for INI file in subdirsHolger Weiss1-0/+2
Add two path names to the list of default INI file locations, as some users/distributions prefer to put configuration files into subdirectories.
2014-06-18lib/parse_ini.c: Add comment on NAGIOS_CONFIG_PATHHolger Weiss1-15/+17
We might want to spit out a warning when NAGIOS_CONFIG_PATH is used. While at it, move the function that handles this environment variable to the bottom.

2014-06-18lib/parse_ini.[ch]: Change code formattingHolger Weiss2-156/+192
Change the indentation and formatting of the code in lib/parse_ini.c. This breaks patches against that file and makes it harder to track its history, but it (hopefully) improves readability a lot.
2014-06-18lib/parse_ini.c: Don't cast malloc(3) resultHolger Weiss1-2/+2
There's no need to cast malloc(3)'s return value.
2014-06-18lib/parse_ini.c: Remove outdated comment and codeHolger Weiss1-15/+10
The lib/parse_ini.c:np_get_defaults() function now dies if no configuration file is found.
2014-06-18lib/parse_ini.c: Read $MP_CONFIG_FILEHolger Weiss1-1/+2
Read $MP_CONFIG_FILE if that variable is set in the environment.
2014-06-18lib/parse_ini.c: Read "monitoring-plugins.ini"Holger Weiss1-0/+4
Read "monitoring-plugins.ini" if that file exists, but fall back to reading "plugins.ini" or "nagios-plugins.ini" for backward compatibility.
2014-06-18lib/parse_ini.[ch]: Simplify codeHolger Weiss2-110/+49
Rewrite the code that looks up the INI configuration file path (used by the Extra-Opts feature) in order to improve readability. The behaviour should not have changed.
