Q_GETNEXTQUOTA was introduced since linux 4.6, this operation is the
same as Q_GETQUOTA, but it returns quota information for the next ID
greater than or equal to id that has a quota set.

@Jan, @Cyril: Do we want to generally avoid loading <linux/types.h> if not really needed?
__u64 can be uint64_t etc (as it's also visible in struct dqblk in <sys/quota.h>
in various libc headers).
We used this approach for /usr/include/linux/bpf.h and for fanotify fixes for
musl (testcases/kernel/syscalls/fanotify/fanotify.h).
So unless you're against this approach here I'll change it before merge
(and add this info to next version of library API writing guidelines patch
https://patchwork.ozlabs.org/patch/1166786/).

Not

I'll change it during merge (nit, the code is what matters, not formatting, of course).

This is not needed (getnextquota_nsup is static and it's called just once, I'll
remove it before merge).

Does EINVAL really mans not supported? Shouldn't be just for ENOSYS

Looking at kernel sources - this does not look as not supported, but rather a
failure (we might want to add some test for EINVAL):
if (!qid_has_mapping(sb->s_user_ns, qid))
return -EINVAL;
kernel fs/quota/quota.c
/*
* Return quota for next active quota >= this id, if any exists,
* otherwise return -ENOENT via ->get_nextdqblk
*/
static int quota_getnextquota(struct super_block *sb, int type, qid_t id,
void __user *addr)
{
struct kqid qid;
struct qc_dqblk fdq;
struct if_nextdqblk idq;
int ret;
if (!sb->s_qcop->get_nextdqblk)
return -ENOSYS;
qid = make_kqid(current_user_ns(), type, id);
if (!qid_has_mapping(sb->s_user_ns, qid))
return -EINVAL;
ret = sb->s_qcop->get_nextdqblk(sb, &qid, &fdq);
if (ret)
return ret;
/* struct if_nextdqblk is a superset of struct if_dqblk */
copy_to_if_dqblk((struct if_dqblk *)&idq, &fdq);
idq.dqb_id = from_kqid(current_user_ns(), qid);
if (copy_to_user(addr, &idq, sizeof(idq)))
return -EFAULT;
return 0;
}

+ general question: do we want always test against kernel headers or libc
headers? Libc is often outdated, so mostly it'd be our fallback to be tested.
Ideally both kernel and libc header should be tested, but that's not easily
achievable.
Kind regards,
Petr

IMHO, We often test libc and it usually includes kernel headers ie.
<sys/quota.h> <sys/prctl.h>. I perfet to check one except that glibc and
kernel they have themselves implementation . If the struct or variable
is not defined, we can define it in ltp lapi headers. Then we can avoid
build error and increase coverage(because kernel may implement it).

Yep. I'm ok with using libc headers (increased coverage), but we need good
checks anyway for other libc (at least for musl; bionic also like glibc uses
internally kernel headers, uclibc-ng usually embeds kernel header parts and
strives to be glibc compatible anyway).

Hi Petr
Yes. I check <sys/quota.h> and <sys/prctl.h> on musl libc[1] and they don't include linux header files.
So I think checking both kernel and libc headers on other libc(musl,bionic) is meaningful.
ps: If our travis-ci has a target with musl, I think it will be better. I don't know whether possible.

I have no objection about using uint64_t becuase Q_GETNEXTQUOTA man-pages also uses it.
I used struct if_nextdqblk as same as <linux/quota.h> defined. But I don't know why we can't use
<linux/type.h> in lapi/quotactl.h and I also use it in lapi/seccomp.h. IMHO, they affected nothing.
Or, they have some redefined errors or not having this headers files in special linux distribution.

Hi Petr
look do_quotactl function in fs/quota/quota.c.
static int do_quotactl(struct super_block *sb, int type, int cmd, qid_t id,
?????????????????????? void __user *addr, const struct path *path)
{
??? switch (cmd) {
??????? case Q_QUOTAON:
??????????????? return quota_quotaon(sb, type, id, path);
??????? case Q_QUOTAOFF:
??????????????? return quota_quotaoff(sb, type);
??????? case Q_GETFMT:
??????????????? return quota_getfmt(sb, type, addr);
??????? case Q_GETINFO:
??? ??? ......
??? ???? default:
??????????????? return -EINVAL;
??????? }
}
So if it doesn't have Q_GETNEXTQUOTA cmd, it should report EINVAL(we use correct argument and correct environment, so there is no failure).

Based on Jan's comment [1], maybe he meant it specifically for __kernel_fsid_t in
fanotify.h, not as a general approach. __kernel_fsid_t is more complicated than
uint64_t. That's why I'm asking whether there is a general approach we want to
take.

Hi Petr
I see. Now, I think we should avoid to use <linux/types.h>?? because on musl? libc doesn't have it.
Also ,If we use uint64_t, they still failed on 2.6.32-754.el6.x86_64 with undefined . Or, we should use TST_ABI to define uint64_t them
on myself.
Thanks

IMHO <linux/types.h> are always installed from kernel, not from libc
(packaged result of make headers_install run from kernel sources).

Hm, that what I said: using kernel headers is imho easier that using libc
headers (fewer problems with compatibility).
Anyway, I don't want to block this patchset.
We can always merge it as it is and sort/fix this problem later.
Kind regards,
Petr

Oh, you are right. For this case, using <linux/types.h> is right that we don't have situation such as fanotify .

Yes. kernel header is more eaiser that libc. Thanks.

Yes, we generally try to avoid including kernel headers. Our style-guide says
"Don't use +linux/+ headers if at all possible". uapi on older distros
was more prone to cause LTP build errors.

Thank you for pointing out docs, I completely forgot on this page.
BTW it needs some update (examples use old API, linux_syscall_numbers.h).
Also not sure if everything else still applies (4. Call APIs that don't require
freeing up resources on failure first, 2. Sort headers).
> > Also ,If we use uint64_t, they still failed on 2.6.32-754.el6.x86_64 with undefined . Or, we should use TST_ABI to define uint64_t them
Jan, are you aware of this problem?
Xu, I'm not sure if you're talking about uint64_t problematic in <linux/types.h>
(as you mention kernel) or problem in glibc <sys/types.h> / <stdint.h> / <inttypes.h>?
We have lots of code which is using some of these 3 libc headers, does it fail
on 2.6.32?
Does anybody compile for 2.6.32?
I know we want to keep support for 2.6.x (we had some discussion in the past).
Than it'd be good to have travis build for kernel 2.6.x.
Back to patchset. I suggest to merge it as it is and I'll prepare patches, which
use <sys/types.h> in our tests.
Kind regards,
Petr

I'm not, it should be defined in stdint.h.

I think RH still does compile latest for regression tests. RHEL6 will be in
sustaining for couple more years.

Thanks for info. Sorry I forgot, we have CentOS 6.10 in travis, that should be
enough for testing build in old toolchain.

Q_XGETQSTATV returns XFS filesystem-specific quota information in the fs_quota_statv
pointed to by addr. The qs_version field of the structure should be filled with the
version of the structure supported by the caller (for now, only FS_QSTAT_VERSION1
is supported).
Also, cover group quota like quotactl01.c.
Move common code to quota02.h, so we can use it for comming quotactl05.c to test project
quota on xfs filesystem.

This is a variant about quotactl01.c and used to test project quota.
I split it into a new case instead of adding it in quotaclt01.c because
two points:
1)Before linux 4.10, ext4 doesn't support project quota.
2)On old kernel, kernel doesn't permit mount both prjquota and grpquota together.

This is a variant about quotactl02.c and used to test project quota.
I split it into a new case instead of adding it in quotaclt02.c because
kernel doesn't permit mount both group and project quota before
commit d892d5864f02 ("xfs: Start using pquotaino from the superblock.").

Hi Xu,
> I cleanup the quotactl code and add project quota test for quotactl.
> Thanks to Jan Kara with support about quota.
Whole patchset merged, following with changes for and quotactl.h seccomp.h to
use libc headers.
Thanks for your work!
Kind regards,
Petr
