But if building from git://sourceware.org/git/systemtap.git it does work with 18.04. Many thanks for the find, I find systemtap indispensable. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1795545 Title: Systemtap incompatible with ubuntu 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemtap/+bug/1795545/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

It tried it, here's that file with the patch:
version = 4
fh = & @nfsd4_compound_state($cstate)->current_fh
if (@defined($u)) {
count = $u->read->rd_length
offset = $u->read->rd_offset
vec = $rqstp->rq_vec
vlen = $u->read->rd_vlen
} else {
count = $read->rd_length
offset = $read->rd_offset
vec = $rqstp->rq_vec
vlen = $read->rd_vlen
}
uid = __rqstp_uid($rqstp)
gid = __rqstp_gid($rqstp)
I installed systemtap-4.0, ran ./configure --prefix=/share/apps/systemtap-4.0;
make; make install
Then ran it:
root@nas-12-1:/share/apps/systemtap-4.0# ./bin/stap
./share/systemtap/examples/network/nfsd-trace.stp

I'll try building the current git version and see if that helps.

Hi - This commit appears to fix this problem. https://sourceware.org/git/gitweb.cgi?p=systemtap.git;a=commitdiff;h=8bc64034509474bee3fb7996b2a9e74c8bc27281 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1795545 Title: Systemtap incompatible with ubuntu 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemtap/+bug/1795545/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1795545] [NEW] Systemtap incompatible with ubuntu 18.04
Public bug reported:
Under 16.04 I ran run:
$ stap nfsd-trace.stp
Mon Oct 1 19:48:05 2018 PDT 10.22.7.20:50434 nfsd.proc4.lookup grep
/export/1/blank/build.2018-08-22/bin/grep
Works great.
Under 18.04 I tried:
# stap nfsd-trace.stp
semantic error: while processing probe
module("nfsd").function("nfsd4_lookup@/build/linux-lZKWha/linux-4.15.0/fs/nfsd/nfs4proc.c:735").call
from: nfsd.proc4.lookup from: nfsd.proc.lookup from: nfsd.proc.entries from:
nfsd.proc.entries
The kernel being used:
Linux nas-7-0 4.15.0-22-generic #24-Ubuntu SMP Wed May 16 12:15:17 UTC 2018
x86_64 x86_64 x86_64 GNU/Linux
I thought I might need a newer systemtap, so I installed it from git on Sept
27th 2018. So the same run:
/share/apps/systemtap-2018-09-27# ./bin/stap
./share/systemtap/examples/network/nfsd-trace.stp
semantic error: while processing probe
module("nfsd").function("nfsd4_read@/build/linux-lZKWha/linux-4.15.0/fs/nfsd/nfs4proc.c:744").call
from: nfsd.proc4.read from: nfsd.proc.read from: nfsd.proc.entries from:
nfsd.proc.entries
Other scripts like iostats.stp work as expected.
So basically from what I can tell the neither the ubuntu provided
systemtap, nor the upstream systemtap works with the widely circulated
nfsd-trace.stp file. It's been available from redhat's documentation as
well as part of the upstream source under examples.
I expected the 18.04 result of "stap nfsd-trace.stp" to be much like the
16.04 result. Showing a log of NFS related I/O, path names, time
stamps, etc.
Other NFS related scripts like nfsd-recent.stp works.
