Now + server is restarted + server opens user-1000.journal and writes entries to it... +BAM! duplicate seqnums for the same seqnum_id. + +Now, we usually don't see that happen, because system.journal +is closed last, and opened first. Since usually at least one +message is written during boot and lands in the system.journal, +the seqnum is initialized from it, and is set to a number higher +than than anything found in user journals. Nevertheless, if +system.journal is corrupted and is rotated, it can happen that +an entry is written to the user journal with a seqnum that is +a duplicate with an entry found in the corrupted system.journal~. +When browsing the journal, journalctl can fall into a loop +where it tries to follow the seqnums, and tries to go the +next location by seqnum, and is transported back in time to +to the older duplicate seqnum. There is not way to find +out the maximum seqnum used in a multiple files, without +actually looking at all of them. But we don't want to do +that because it would be slow, and actually it isn't really +possible, because a file might e.g. be temporarily unaccessible. + +Fix the problem by using different seqnum series for user +journals. Using the same seqnum series for rotated journals +is still fine, because we know that nothing will write +to the rotated journal anymore. + +Likely related: +https://bugs.freedesktop.org/show_bug.cgi?id=64566 +https://bugs.freedesktop.org/show_bug.cgi?id=59856 +https://bugs.freedesktop.org/show_bug.cgi?id=64296 +https://bugs.archlinux.org/task/35581 +https://bugzilla.novell.com/show_bug.cgi?id=817778 + +Possibly related: +https://bugs.freedesktop.org/show_bug.cgi?id=64293 + +Conflicts: + src/journal/journald-server.c +--- + src/journal/journald-server.c | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +diff --git a/src/journal/journald-server.c b/src/journal/journald-server.c +index cc52b8a..cde63c8 100644 +--- a/src/journal/journald-server.c ++++ b/src/journal/journald-server.c +@@ -280,7 +280,7 @@ static JournalFile* find_journal(Server *s, uid_t uid) { + journal_file_close(f);
