[rsyslog] imfile buffer overflow master-candidate
I've found a buffer overflow in imfile in the master-candidate branch. To reproduce, make an imfile config that uses a relative path rather than absolute to a file: ``` module(load="imfile" PollingInterval="10") input( type="imfile" tag="crash" File="crashme" ) *.* /var/log/syslog ``` This results in: ``` 3146.392981790:main thread: deletestateonfiledelete: (unset) 3146.392987727:main thread: addmetadata: (unset) 3146.392993638:main thread: addceetag: (unset) 3146.392999527:main thread: statefile: (unset) *** buffer overflow detected ***: rsyslogd terminated === Backtrace: = /lib/x86_64-linux-gnu/libc.so.6(+0x7338f)[0x7f286982b38f] /lib/x86_64-linux-gnu/libc.so.6(__fortify_fail+0x5c)[0x7f28698c2c9c] /lib/x86_64-linux-gnu/libc.so.6(+0x109b60)[0x7f28698c1b60] /usr/local/lib/rsyslog/imfile.so(+0x22cd)[0x7f286919f2cd] /usr/local/lib/rsyslog/imfile.so(+0x254d)[0x7f286919f54d] rsyslogd(inputProcessCnf+0x99)[0x4147a9] rsyslogd(cnfDoObj+0x90)[0x414ba0] rsyslogd(yyparse+0xbae)[0x45435e] rsyslogd(load+0xc35)[0x414145] rsyslogd(initAll+0x5ef)[0x448e2f] rsyslogd(main+0x30)[0x40dfe0] /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf5)[0x7f28697d9ec5] rsyslogd[0x40e35a] ``` I don't have time to dig into it today but wanted to go ahead and report it. If I correctly use an absolute path to the file (I used a relative by mistake when testing and found this), things work as expected. If I get some time tomorrow to dig into it I will!

[rsyslog] Forwarding to multiple syslog servers and HA
Hi folks! I'm looking at setting up some systems, where rsyslog is reading logs from disk and forwarding them to two centralise servers at the same time. I have a question around a specific failure scenario: If one of the two central servers goes down, how does rsyslog behave? Does it keep sending to the other server? Is the tracking and queuing for each destination independent, or are logs sent serially to each destination and one server being down would block delivery to other remote destinations? I was thinking about using the omfwd module (so no RELP, until I can get the upstream syslog servers converted to rsyslog, too). Does that seem reasonable?

If you use UDP, you don't know if the log is getting to the destination or not. If you use TCP, and the network queues fill up, processing will stop until it clears (if you have a separate queue for that output, only processing on that queue will stop, if you share a queue with some other output, processing for that other output will stop as well. each queue has a worker thread that loops through all outputs for that queue, trying to deliver to them in turn. If one blocks that worker has the choice (configurable) to either block, or throw away the log for that output and continue to the next one. by default rsyslog has one main queue. you can configure additional queues for either actions or rulesets. It's strongly recommended that you use a current version and the new syntax when configuring queues. It makes it MUCH clearer what is happening.

If not, I'll grab 8.16. 7.4.7 is new enough to have the new syntax, but there are a LOT of fixes and new features by 8.16 (8.17 is due to be released tuesday). For end nodes that just need to send logs in to your central server, 7.4.7 is probably good enough (although if you trip over any bugs on it, just go to a current version). But on your log relays and central servers, or anywhere that you start doing more complex stuff, just go to the current version. When you ask questions here, we are always going to be thinking in terms of the most current version. Bugs get fixed in the most current version and only some get backported by the distro to the older versions.
