[Bug 1698388] Re: Assertion failure in journal-remote-parse.c

[Dan Streetman]

I at least verified the update doesn't appear to cause any obvious
regression:

start server:

ubuntu at lp1698388-x:~$ dpkg -l |grep systemd-journal-remote
ii  systemd-journal-remote           229-4ubuntu21.29                           amd64        tools for sending and receiving remote journal logs
ubuntu at lp1698388-x:~$ mkdir /tmp/journal-test
ubuntu at lp1698388-x:~$ /lib/systemd/systemd-journal-remote -o /tmp/journal-test --listen-http=127.0.0.1:7000 

then in separate terminal:

ubuntu at lp1698388-x:~$ /lib/systemd/systemd-journal-upload -u
http://127.0.0.1:7000

then check if uploaded:

ubuntu at lp1698388-x:~$ ls -l /tmp/journal-test/
total 8196
-rw-r----- 1 ubuntu ubuntu 8388608 Sep 10 17:03 remote-127.0.0.1.journal
ubuntu at lp1698388-x:~$ journalctl --file /tmp/journal-test/remote-127.0.0.1.journal | wc -l
1842

Title:
  Assertion failure in journal-remote-parse.c

Status in systemd package in Ubuntu:
  Fix Released
Status in systemd source package in Xenial:
  Fix Committed

Bug description:
  [impact]

  assertion failure in systemd-journal-remote

  [test case]

  only happens under specific circumstances, which is unclear exactly
  how to reproduce it

  [regression potential]

  any regression would likely result in the failure/crash of systemd-
  journal-remote program while processing data from a remote source.

  [scope]

  this is needed only for x.

  this is fixed by commit 9ba37525d0ef3d144a50ed5fd4710573e92b7ec1 which
  is included upstream starting in v230, so this is already included in
  b and later.

  [original description]

  I am observing the following assertion failure in systemd-journal-
  remote:

  Assertion 'source->filled <= source->size' failed at ../src/journal-
  remote/journal-remote-parse.c:95, function get_line(). Aborting.

  Systemd version:

  systemd 229
  +PAM +AUDIT +SELINUX +IMA +APPARMOR +SMACK +SYSVINIT +UTMP +LIBCRYPTSETUP +GCRYPT +GNUTLS +ACL +XZ -LZ4 +SECCOMP +BLKID +ELFUTILS +KMOD -IDN

  Ubuntu release:

  Description:	Ubuntu 16.04.1 LTS
  Release:	16.04

  Package version:

  systemd:
    Installed: 229-4ubuntu13
    Candidate: 229-4ubuntu17

  It looks like this issue has been fixed upstream in v230, specifically
  in commit 9ba37525d0ef3d144a50ed5fd4710573e92b7ec1. Could this
  particular commit be backported?
