Red Hat Bugzilla – Bug 84211
Uknown/undecoded system calls in strace output
Last modified: 2007-11-30 17:06:52 EST
Description of problem: The strace utility doesn't know about all the system
calls that can be executed on an IA64/IPF box with Advanced Server. This
occurs both in the original release (2.4.18-e.12) and the latest errata kernel
Version-Release number of selected component (if applicable):
# rpm -q strace kernel-smp
How reproducible: 100% (always)
Steps to Reproduce:
1. Install 2.1AS for IPF
2. Upgrade to latest errata packages
3. run "strace top -n 1" | grep -i "^sys"
Actual results: attached, shows undecoded/unknown system calls.
Expected results: All system calls known.

These bugs are fixed in the Rawhide strace rpm, which you can rebuild
from the srpm on AS2.1 without difficulty (rpmbuild --rebuild).
Changing state to MODIFIED. Also, do you know if this will be posted as an
errata to AS2.1/AW2.1 for IA64 anytime soon?
You can't change the bug state, but I did so in case it makes you happy.
There is an outstanding issue relating to strace -f on ia64 that I hope will be
resolved very soon. That is the only thing holding up me making both an strace
source release and an erratum version. So the process towards having an erratum
will start quite soon, though I can't tell you anything definitive about when it
will be formally released to AS customers.
Changing product to Red Hat Enterprise Linux Beta
Verified fix in taroon alpha3 for ia64.
FWIW, strace still shows SYS_1210 and SYS_1214 in AS2.1 update 2. Will there
ever be an errata/update for AS2.1 ??
This is _fixed_ in taroon, but was closed in bugzilla for the AS2.1 stuff.
This is STILL b0rken in 2.1 -- please add the fix to 2.1 update 3.
There are two Bugzillas for this IPF issue:
*90007 currently against 2.1 (this bug) and closed for TAROON
*84211 currently against Taroon though reopened against 2.1
Therefore, changing Products/Versions to reflect current dispositions
*90007 against Taroon as fixes in Alpha3
*84211 against 2.1 with target of QU3 (HP considers blocker); severity set to
HP-IPF considers MUSTFIX for Update3. Need Tim.CHris approval to add blocker bug.
An errata has been issued which should help the problem described in this bug report.
This report is therefore being closed with a resolution of ERRATA. For more information

this bug report if the solution does not work for you.
