After upgrade FreeBSD 10.3 from r307955 to r317936 DTrace is broken:
The output of
dtrace -n 'dtrace:::BEGIN { printf("Hello FreeBSD!\n"); }'
gives
dtrace: invalid probe specifier dtrace:::BEGIN { printf("Hello
FreeBSD!\n"); }: "/usr/lib/dtrace/ip.d", line 245: m_data is not a
member of struct mbuf
The file ip.d was replaced with commit of Revision 317375. Using the
previus version of the file /usr/lib/dtrace/ip.d lets DTrace work again.
Another problem with DTrace now are error messages in /var/log/messages
while running "dtrace -vl" like
<kern.crit> dsssrvt7 kernel: fbt_getargdesc(1296): Unknown function!
<kern.crit> dsssrvt7 last message repeated 45 times
This problem looks like the problem described in the old PR kern/160275.
I do not know how to fix this.
