2023-01-30check_http: Fix memory reallocation error in chunk decoding logicLorenz Kästle1-4/+3
This patch should fix an error with the way memory reallocation was used, which resulted in "realloc(): invalid next size". It is not completely clear to me as to what caused this problem, but apparently one can not depend handing a pointer to "realloc(3)" and expect that it still works afterwards, but one should/must use the one returned by the function. Also this patch replaces a variable which was used to remember the position in the array by just computing that from the current values.

2023-01-20fix check_snmp regex matchesSven Nierlein1-2/+21
the multiplier function always tried to extract a number, even if the result is a string because of using a mib. before: ``` ./check_snmp -H hostname -P2c -c public -o IF-MIB::ifAdminStatus.11466 -vvv -r 0 /usr/bin/snmpget -Le -t 10 -r 5 -m ALL -v 2c [context] [authpriv] 10.0.13.11:161 IF-MIB::ifAdminStatus.11466 IF-MIB::ifAdminStatus.11466 = INTEGER: up(1) Processing oid 1 (line 1) oidname: IF-MIB::ifAdminStatus.11466 response: = INTEGER: up(1) SNMP OK - 0 | IF-MIB::ifAdminStatus.11466=0;; ``` the regexp 0 matches, even if the actual result is "up(1)". after this patch: ``` ./check_snmp -H hostname -P2c -c public -o IF-MIB::ifAdminStatus.11466 -vvv -r 0 /usr/bin/snmpget -Le -t 10 -r 5 -m ALL -v 2c [context] [authpriv] 10.0.13.11:161 IF-MIB::ifAdminStatus.11466 IF-MIB::ifAdminStatus.11466 = INTEGER: up(1) Processing oid 1 (line 1) oidname: IF-MIB::ifAdminStatus.11466 response: = INTEGER: up(1) SNMP CRITICAL - *up(1)* | ```

2022-12-22check_curl: fix checking large bodys (#1823)Sven Nierlein1-2/+5
check_curl fails on large pages: HTTP CRITICAL - Invalid HTTP response received from host on port 5080: cURL returned 23 - Failure writing output to destination for example trying to run check_curl on the test from #1822 I guess the idea is to double the buffer size each time it is to small. But the code exponentially grows the buffer size which works well 2-3 times, but then fails.
2022-12-22make check_http faster with larger filesDanijel Tasov1-2/+7
The current implementation becomes exponentially slower with growing response size.

2022-11-04Removing is_pg_dbname alltogether,using postgres API. (Closes: #1660) (#1803)waja1-44/+4
The problem is that check_pgsql validates the Database name and has different assumptions that postgres itself. I fail to see a reason to validate the database name here. Postgres'es API should do this - So i would suggest a fix like this by removing is_pg_dbname alltogether. Co-authored-by: Florian Lohoff <f@zz.de>

//test.server.com/folder Referenced redirect of the format //www.server.com/folder would result in check_http trying to contact http://hostname:80//www.server.com/folder instead of http://www.server.com/folder. Referenced redirect of this format is listed in rfc3986 ( https://tools.ietf.org/html/rfc3986 ). It should work as expected now.
