1.7.0-67: syslog() not working properly - possible bug in writev() ?

[Christian Franke]

syslog() produces bogus lines in /var/log/messages.

Testcase (with syslog-ng):

$ echo -e 'one\ntwo\nthree' | logger -t test

$ tail /var/log/messages
...
Dec  2 10:12:31 localhost kernel:
Dec  2 10:12:31 localhost test: one
Dec  2 10:12:31 localhost kernel:
Dec  2 10:12:31 localhost test: two
Dec  2 10:12:31 localhost kernel:
Dec  2 10:12:31 localhost test: three

I presume that the root of the problem is that the

  writev(fd, { {"<PRI style="margin:0px;">", . }, { "MSG", . } }, 2)

used within syslog() sends "<PRI style="margin:0px;">" and "MSG" in two
separate datagrams to /dev/log.
