2020-04-03Fix Coverity Defect CID-349684 (#8586)thiagoftsm
This PR brought a test before to call the function `health_add_params` to avoid memory leak.
2020-04-03Fix Coverity defects (#8579)Andrew Moss
Fix Coverity CID355287 and CID355289: technically it is a false-positive but it is easier to put a pattern in the code that they can recognise as a sanitizer. The compiler will remove it during optimization. Fix CID353973: the security condition is unlikely to occur but we can avoid it completely. Fix resource leak from CID 355286 and CID 355288. Fixing new resource leak introduced by a previous commit (CID355449)

2020-03-31Improve the behavior of claiming (#8516)Andrew Moss
The default cloud url has been updated to app.netdata.cloud ready for the release. The claiming process now checks the current user executing claiming and refuses to perform the claim for the wrong user. If the current UID is 0 then claiming proceeds but the file ownership is adjusted to be the correct netdata user. The default expected user is `netdata` unless the script can identify the user from the current configuration. After the claiming script is executed the CLI is used to reload the claiming state.

Reduce error to info. Fixes #7644 where only uv threads were not renamed
2019-12-20Set standard name to non-libnetdata threads (libuv, pthread) (#7584)Adrien Mahieux
* [libnetdata/threads] Add uv_thread_set_name This is inspired from thread_set_name() but for libuv threads. Both are based on pthread, but for uv we need to call it with the uv_thread_t pointer, instead of being the thread that calls the function for itself. * [exporting] Set libuv threadname to "EXPORTING-index" * [database/engine] Set libuv thread name to "DBENGINE" * [daemon/command] Set libuv thread name to "DAEMON-COMMAND" * [collectors/proc] Set pthread name to "PLUGIN[cpuidle]" * Use new 'thread_set_name_np' name

2019-11-14Updating the Travis pipeline (issue 7189) (#7312)Andrew Moss
Added a linting pass. This is non-blocking but will output a measure of how much each .c and .h file deviates from our current .clang format. Changed the standard build to include all of the warning that we are using in dev. Added the dependencies for dbengine and confirmed that the standard build enables dbengine. Fixed the original warnings.

2019-10-24Fixing DNS-lookup performance issue on FreeBSD. (#7132)Andrew Moss
Our default configuration includes: allow connections from = localhost * allow management from = localhost The problem occurs when a connection is received that passes the `allow connections` pattern match, but fails the ACL check for `allow management`. During the failure processing path the DNS lookup is triggered to allow the FQDN to be checked against the pattern. On a FreeBSD system this lookup fails more slowly than linux and causes a visible performance problem during stress-testing. The fix adds a heuristic to analyse the patterns and determine if it is possible to match a DNS name, or only match a numeric IP address (either IPv4 or IPv6), or only match a constant value. This heuristic is used to disable the DNS checks when they cannot produce anything that may match the pattern. Each heuristic is evaluated once, when the configuration is loaded, not per-connection to the agent. Because the heuristic is not exact it can be overridden using the new config options for each of the ACL connection filters to set it to "yes", "no" or "heuristic". The default for everything *except* the netdata.conf ACL is "heuristic". Because of the numeric-patterns in the netdata.conf ACL the default is set to "no".
2019-10-21Netdata not returning correct value for unknow variables (#6984)thiagoftsm
* health_nan: fix result The expression evaluate was keeping the value zero when there was a wrong variable, but according our documentation the correct result would be NAN, this commit fixes this * health_nan: mapping * health_nan: Set variable After few tests, I am setting the NAN value to the variable in the correct place
2019-10-17feat(reaper): Add process reaper support (#7059)Steven Hartland
##### Summary Add a child process reaper to the main netdata app if running as init (pid = 1). This prevents zombie processes when a child is re-parented to netdata when its running in a container. Also: * Few style cleanups to match surrounding code. Fixes: #6033 ##### Component Name netdata binary ##### Additional Information This re-purposes old commented out code in `popen.c`, which already implemented part of the required process tracking. Without this on a standard netdata docker install we saw at least one zombie `timeout` process straight after the container was started.
2019-10-15Clang warnings (#7090)thiagoftsm

* coverity_20190924: Fix 215633 In the switch the library stops case this pointer is NULL, so there is not necessity to processed with tests * coverity_20190924: Fix 338067 The current code tries to copy the same size of the variable, another possible solution would be to use a function to sanitize the code, I will try this first * coverity_20190924: Fix 348638 Considering that we are testing the variable value one line above The division will always happen * coverity_20190924: Fix 348640 For this specific case we do not have the possibility to have memory leak, valgrind confirms this, but I am adding a new variable here to the stack to discard the warning

2019-09-18Allow hostnames in Access Control Lists (#6796)Andrew Moss
##### Summary The Access Control List (ACL) configuration parameters can now use hostnames with simple patterns. Incoming connections are resolved using reverse DNS to obtain the hostname. Where a hostname is resolved, forward DNS resolution is performed to check the IP address is really associated with the hostname. If the checks pass then the patterns supplied are checked. Any patterns supplied for numeric ip addresses are also checked. ##### Component Name daemon ##### Additional Information Fixes #6438 * Reverse lookup on ip to get hostname * Forward lookup on hostname to get IP addresses. * Validation that the incomming ip is associated with the host. If these checks fail the hostname is discarded so it cannot match against the access-list patterns. If these checks validate the ip successfully then the resolved hostname is pattern-matched as described in the previous commit.
2019-09-04[libnetdata/thread] Set thread name from tag (#6745)Adrien Mahieux
* [libnetdata/thread] Set thread name from tag When calling netdata_thread_create, you can provide a tag to identify the thread in the error message This patch uses this tag to rename the thread if supported by the pthread distribution to allow better identification of the thread. This have helped identify the bug #6741 Sample output: ps -L -o tid,pid,comm,args -p $(pgrep netdata) TID PID COMMAND COMMAND 5123 5123 netdata ./netdata -D 5133 5123 PLUGIN[proc] ./netdata -D 5134 5123 netdata ./netdata -D 5135 5123 PLUGIN[cgroups] ./netdata -D 5136 5123 netdata ./netdata -D 5137 5123 STATSD ./netdata -D 5138 5123 BACKENDS ./netdata -D 5139 5123 netdata ./netdata -D 5140 5123 PLUGINSD ./netdata -D 5141 5123 netdata ./netdata -D 5142 5123 HEALTH ./netdata -D 5143 5123 netdata ./netdata -D 5145 5123 netdata ./netdata -D 5146 5123 PLUGINSD ./netdata -D 5147 5123 PLUGINSD[apps] ./netdata -D 5148 5123 netdata ./netdata -D 5150 5123 netdata ./netdata -D 5151 5123 STATSD ./netdata -D * [libnetdata/thread] Improve set thread title Added error check and fixed limit of 15 chars for thread name. ``` ps -L -o tid,pid,comm,args -p $(pgrep netdata) TID PID COMMAND COMMAND 14521 14521 netdata ./netdata -D 14531 14521 PLUGIN[proc] ./netdata -D 14532 14521 PLUGIN[diskspac ./netdata -D 14533 14521 PLUGIN[cgroups] ./netdata -D 14534 14521 PLUGIN[idlejitt ./netdata -D 14535 14521 STATSD ./netdata -D 14536 14521 BACKENDS ./netdata -D 14537 14521 WEB_SERVER[stat ./netdata -D 14538 14521 PLUGINSD ./netdata -D 14539 14521 HEALTH ./netdata -D 14540 14521 WEB_SERVER[stat ./netdata -D 14541 14521 WEB_SERVER[stat ./netdata -D 14542 14521 WEB_SERVER[stat ./netdata -D 14543 14521 WEB_SERVER[stat ./netdata -D 14544 14521 WEB_SERVER[stat ./netdata -D 14546 14521 STATSD_COLLECTO ./netdata -D 14547 14521 PLUGINSD[python ./netdata -D 14548 14521 PLUGINSD[apps] ./netdata -D ``` * [libnetdata/thread] Moved code to dedicated func * [libnetdata/thread] Wrong return value for thread_set_name * [libnetdata/thread] Remove lval for FreeBSD as defined void * [libnetdata/thread] Change allocation method to stack
