Hi Viresh,
Thank you for creating new tests for LTP.
Unfortunately, this 1/7 patch has overlap with zlang@'s patch[1]. It
probably can not be merged if the patch[1] applies first. But the remaining
part is valuable to LTP, you can drop some of this and rebase your code to
make use of the header file again.
[1] http://lists.linux.it/pipermail/ltp/2020-February/015336.html
[CC zlang, pvorel] to have a look at this.

Regards,
Li Wang

patch.

Thanks for pointing that out Li. I will rebase over zlang's patch once it gets
merged.

I never thought about that earlier, good point. All other comments look fine as
well. Thanks.

Adding #include "lapi/fcntl.h" in case of ?AT_FDCWD? undeclared. It seems
we have to do this for all the tests involves ?AT_FDCWD?.

As this fsmount01.c is duplicated with zlang@'s patch, I suggest rewriting
an enhancement version maybe name fsmount02.c to cover more fsmount
attributes. Since it is named basic fsmount() test, it shouldn't only test
fsmount(fd, 0, 0), right?

I guess we probably need a way to verify the move_mount() does work. The
function ismount() in zlang@'s patch could be extracted into the library as
tst_ismount() for all of these tests.

my fsmount.h header includes <fcntl.h>, won't that be enough ?

I'm afraid it's not enough.
After having a closer look, the reason is that the AT_FDCWD is defined with
condition __USE_ATFILE, the __USE_ATFILE depends on _ATFILE_SOURCE
defined, and _ATFILE_SOURCE needs enable _GNU_SOURCE.
So another effective way is to add '#define _GNU_SOURCE' in front of your
test then that <fcntl.h> will be work for you.
# rpm -qa glibc-headers
glibc-headers-2.5-123
# cat /usr/include/fcntl.h |grep AT_FDCWD -B 2 -A 2
#ifdef __USE_ATFILE
# define AT_FDCWD -100 /* Special value used to indicate
the *at functions should
use the
current working directory.
*/

Unfortunately it won't be enough. LAPI files are here for adding missing
definitions in old distros, which is exactly the case for AT_FDCWD on old RHEL.
I also suggest following change to v7, see diff below (fsmount.h using
"lapi/fcntl.h", thus not needed in fsmount01.c).

+1. But I'd suggest to first merge tests which I sent as v7 [1] (with change
below) and then doing this.

OK, we can add #define _GNU_SOURCE to fsmount01.c, which actually needs it
+ keep <fcntl.h> there and load lapi/fsmount.h later (see below).
But generally this will be the approach for all uses of <fcntl.h> (and probably
some other headers) for old distros. IMHO this change is caused by:
c941736c92 Remove _BSD_SOURCE and _SVID_SOURCE. (glibc-2.20)
c688b41960 Add _DEFAULT_SOURCE feature test macro. (glibc-2.19)
So we can either add it to many places or detect this old glibc and compile with
-D_GNU_SOURCE (but this might break other things).
But that's another story.

So is this diff to v7 better?

To use "lapi/fcntl.h" in v7 is simpler I guess, sometimes we just need to
get compile pass on old distros but not perform it indeed. And that's the
purpose why we need lapi/*.

Sorry, that's a typo. I mean detect Glibc version is not a good idea:).

Agree. IMHO mostly we should use lapi than libc headers (+ put system headers
into lapi files), that'd keep old distros working.

If we do that we have to explicitely check for ENOSYS errno in each
test, quite possibly with a dummy call to the tested syscall in test
setup, because once these calls gets libc wrappers we will no longer
call the tst_syscall() that checks for it.

Hi Viresh,
Thanks for all these cases, that's really helpful.
Although you write cases for each new mount API, each xxxxx01.c case looks
nearly do same things.
That's why I only wrote one case for new-mount currently, due to basic mount
test already can through most of new APIs(except open_tree and fspick). I don't
know if we should write nearly same things in different directories.
Actually I prepared open_tree and fspick test cases(planned to name as newmount02
and newmount03. but the newmount01 has been changed to fsmount01 :), but didn't
sent out, due to I hope to the first case(which does basic changes) can be merged
at first.
All of your xxxxx02.c cases are great! I planned to test more different
parameters of fsconfig() later too. Your invalid parameters test are nice.
As you've sent these cases, I think these should be reviewed at first, avoid
we do same things:) I'll try to help to review V2 patchset too, if I can:-P
Thanks,
Zorro

Yes, I have the same feelings. Below are my 2 cents:
Probably because the APIs should be used to bind together, but it is best
to reflect the focus of each test case. e.g. fsmount01.c as basic test
needs to cover more parameters to verify that all the functionality is
really working. fsmount02.c more like a test target for all error
conditions.
FYI madvise test:

It'd be great if those tests can be merged together with Viresh's patch.

I agree, just that they are all slightly different, and perhaps they can be
improved to test different parameters for the success case as well.
I think all the *02.c files are quite different that way, and perhaps *01.c
tests should do the same.

Heh. I had no clue that anyone else is working on this stuff else I won't have
touched it at all (and saved some time) :)

Thanks for suggesting this way out, and I agree 100% with you.
FWIW, I am working on V2 which I should be able to send by tomorrow max (if
everything goes as planned). Lets see how it looks after that and I would love
to review any improvement patches you may have after these are merged (Please cc
me directly, I haven't opted for receiving emails from ltp list).

Not sure if I understood it very clearly and don't want to spam everyone with an
incorrect patchset still missing this point and so asking here :)
How exactly would the setup() routine look like? Something like this ?
syscall(#NR, ##__VA_ARGS__);

I suggest to use tst_syscall(...);.
A dummy call in setup() just helps check the ENOSYS errno, something like:
$ cat testcases/cve/cve-2016-7117.c |grep setup -A 10
static void setup(void)
{
...
tst_syscall(__NR_recvmmsg, 0, 0, 0, 0, 0);
}

Hi Viresh,
as somebody (probably Li) pointed out fsopen/fsopen01.c is similar to fsmount/fsmount01.c,
so please during rebase drop it. BTW for this dropped test I'd use different
approach (close fd in cleanup function and use tst_brk(TFAIL instead of
tst_res(TBROK and goto):
static void cleanup(void)
{
if (fd > 0)
SAFE_CLOSE(fd);
}
...
if (fd == -1)
tst_brk(TFAIL | TERRNO, "fsopen() failed");
Also you added autotools check for functions (e.g. fsopen) during commits, but I
move them to the first (together with lapi header).
Kind regards,
Petr

Lets review this comment after my V2 series is posted today. It may be better to
keep separate tests.

Yeah, I already saw that. Thanks for that, you did the right thing :)

Could anybody add it to fsmount/fsmount01.c instead?
If anybody don't mind, I'll rename fsopen02.c to fsopen01.c,
remove .min_kver = "5.2" and replace tst_brk with tst_res + return, and merge it:
