Hi,
I did some testing with the LTP Regression Test Suite
(http://ltp.sourceforge.net) inside a VE the last days. When I enable all
capabilites except "setpcap" I get one warning and three failures. When I
run the tests native (in VE0) I get no errors. I tested it with several
Kernels including the latest 2.6.18 and 2.6.20 from the git repository, all
with the same results.
I run the syscall test suite of ltp-20070430 as root with the command:
./runltp -p -q -f syscalls -l `date +"%Y-%m-%d_%H-%M-%S"`
Failed tests: syslog12, ustat01, ustat02
Output:
syslog12
syslog system call: read and/or clear kernel message ring
buffer; set console_loglevel
syslog12 5 FAIL : syslog() returned unexpected
results for
console level less than 0 ; returned 0
(expected -1), errno 0 (expected 22)
syslog12 6 FAIL : syslog() returned unexpected
results for console level
greater than 8 ; returned 0 (expected -1),
errno 0 (expected 22)
ustat0[1-2]
ustat system call: get filesystem statistics
ustat01 1 FAIL : ustat(2) failed and setthe errno to
13
: Permission denied
ustat02 1 PASS : ustat(2) expected failure; Got
errno - EINVAL :
Invalid parameter
ustat02 2 FAIL : ustat(2) failed to produce expected
error; 14, errno:
EFAULT and got 13
As you can see the syslog12 and ustat02 tests fail because they return
other error values than expected. The ustat01 test fails because of
unsufficient permissions.
Is there someone out who wants to confirm or to comment why these System
Call Tests fail?
Mit freundlichen Grüßen / Best Regards

I've reporoduces ustat unexpected EACCES problem and filed report
at http://bugzilla.openvz.org/show_bug.cgi?id=584

1) Fail with ustat() is a openvz bug and it will be fixed in the near future.
2) Fail with syslog() is a normal behavior, but it can be modified specially
for LTP.

But how I mentioned before, the syslog12 test does not fail on my native
machine. So what do you mean exactly by "normal behaviour"?

I meant that if program in VE calls syscall(type, buf, len); with type==8
(set log level) then kernel doesn't permit to do it with no error return.
