Hey everyone,
/* v9 */
Rebased onto current master.
Hopefully we can merge this soon so we can have regular testing asap and
the rebasing is getting a bit tedious too. ;)

This adds the testsuite for idmapped mounts. It has been expanded quite
a bit too since the last version:
- Add a testcase to verify that detached mounts in the new mount api
work correctly.
- Add a full testsuite for idmapped mounts.
- Add two quota tests verifying xfs behavior.
Sorry that it took so long to resend this testsuite but I had to chase
and fix a bug in the new mount API (completely independent of idmapped
mounts) before I could add quota tests because they would otherwise run
danger to render the host mount namespace unuseable due to that bug
(cf. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d3110f256d126b44d34c1f662310cd295877c447)
All tests here pass for me on a kernel with idmapped mounts. The xfs
specific quota tests should go on top of the fixes that Darrick is
currently carrying for 5.12 and which he sent out a little while ago.
Thanks!
Christian

Regression test to verify that creating a series of detached mounts,
attaching them to the filesystem, and unmounting them does not trigger an
integer overflow in ns->mounts causing the kernel to block any new mounts in
count_mounts() and returning ENOSPC because it falsely assumes that the
maximum number of mounts in the mount namespace has been reached, i.e. it
thinks it can't fit the new mounts into the mount namespace anymore.
The test is written in a way that it will leave the host's mount
namespace intact so we are sure to never make the host's mount namespace
unuseable!

Test that xfs quota behave correctly on idmapped mounts.
Mount a scratch device with user and group quota support enabled. Create
directories "unmapped" and "idmapped". Create files in the unampped
mount and verify quota behavior. Create files through the idmapped mount
and verify identical behavior.

+ Specify an idmap for the <target> mount in the format\n\

+ uid:20000:100000:1000 -> map uid 20000 to uid 100000, uid 20001 to uid 100001 [...] in <target>\n\

+ Specify a path to a user namespace whose idmap is to be used.\n\n\

Not directly new in your patch, but I wish we'd have a central header
for missing UAPI bits in xfstests instead of spreading it over
various files.
Otherwise looks good:

FWIW if you (or anyone else) /does/ create a src/linux_calls.h or
similar for things like this, I will totally start adding things to it
instead of scattering them everywhere. :)

I do usually have in my C projects two .h files (without corresponding
.c files):
1. syscall_numbers.h
https://github.com/lxc/lxc/blob/master/src/lxc/syscall_numbers.h
Where syscall_numbers defines the missing syscall numbers. For new
syscalls in the style exhibited in this patch and for legacy syscalls
it's a bit more nasty (i.e. syscalls before we unified numbering [apart
from alpha]):
#ifndef __NR_memfd_create
#if defined __i386__
#define __NR_memfd_create 356
#elif defined __x86_64__
#define __NR_memfd_create 319
#elif defined __arm__
#define __NR_memfd_create 385
#elif defined __aarch64__
#define __NR_memfd_create 279
#elif defined __s390__
#define __NR_memfd_create 350
#elif defined __powerpc__
#define __NR_memfd_create 360
#elif defined __riscv
#define __NR_memfd_create 279
#elif defined __sparc__
#define __NR_memfd_create 348
#elif defined __blackfin__
#define __NR_memfd_create 390
#elif defined __ia64__
#define __NR_memfd_create 1340
#elif defined _MIPS_SIM
#if _MIPS_SIM == _MIPS_SIM_ABI32
#define __NR_memfd_create 4354
#endif
#if _MIPS_SIM == _MIPS_SIM_NABI32
#define __NR_memfd_create 6318
#endif
#if _MIPS_SIM == _MIPS_SIM_ABI64
#define __NR_memfd_create 5314
#endif
#else
#define -1
#warning "__NR_memfd_create not defined for your architecture"
#endif
#endif
2. syscall_wrappers.h
https://github.com/lxc/lxc/blob/master/src/lxc/syscall_wrappers.h
Where syscall_wrappers.h defines minimal wrappers for missing
syscalls and their corresponding types.
#ifndef HAVE_SYS_SIGNALFD_H
struct signalfd_siginfo {
uint32_t ssi_signo;
int32_t ssi_errno;
int32_t ssi_code;
uint32_t ssi_pid;
uint32_t ssi_uid;
int32_t ssi_fd;
uint32_t ssi_tid;
uint32_t ssi_band;
uint32_t ssi_overrun;
uint32_t ssi_trapno;
int32_t ssi_status;
int32_t ssi_int;
uint64_t ssi_ptr;
uint64_t ssi_utime;
uint64_t ssi_stime;
uint64_t ssi_addr;
uint8_t __pad[48];
};
static inline int signalfd(int fd, const sigset_t *mask, int flags)
{
int retval;
retval = syscall(__NR_signalfd4, fd, mask, _NSIG / 8, flags);
#ifdef __NR_signalfd
if (errno == ENOSYS && flags == 0)
retval = syscall(__NR_signalfd, fd, mask, _NSIG / 8);
#endif
return retval;
}
#endif
Something like this might also work for xfstests.

Yeah, not 5 minutes later someone emailed me a bug report that fstests
doesn't build on Ubuntu 16.04 due to its kernel headers not knowing
about fsxattr, so I guess I'll have a patch out adding this exact header
file later today.

Or, as my own notes reminded me, put all that stuff in a header file,
and include it from src/global.h if the system libraries didn't pull it
in.

Sorry for the late review.. You don't have to rebase on every release if
updating the test seq number is the only thing changed. Seq number
conflicts all the time, usually I can fix it on commit.
Patch 2 is missing from the list, maybe it's too big to post, could you
please provide a git repo so I can pull from there?
Some minor comments go to specific patch.
Thanks,
Eryu

Seems this is mostly copied from _filter_quota_report(), just remove the
$id and $bsize check in the beginning, is it possible to re-use
_filter_quota_report?

And above two functions are copied from xfs/050 and xfs/299, could you
please re-factor them into a common helper so they could be shared by
tests?

Seems this could be made into a generic _scratch_mount_idmapped()
helper.

And turn this into _scratch_umount_idmapped()

s/umount/$UMOUNT_PROG/. And it'd be good to add some comments to desribe
why lazy umount is needed.

Remove the leading "_" for local functions.

_Sigh_, this seems like another vger issue. The individual Ccs/Tos
should've all gotten the patch but it's missing from the list. This is a
pattern I've seen quite a few times recently with vger. There's nothing
to do apart from complain about it to the vger maintainer. :)

For sure. It's available in three locations:
https://git.kernel.org/pub/scm/linux/kernel/git/brauner/xfstests-dev.git/log/?h=idmapped_mounts_v2
https://gitlab.com/brauner/xfstests/-/tree/idmapped_mounts_v2
https://github.com/brauner/xfstests/tree/idmapped_mounts_v2
(Are you fixing the things you pointed out in the individual patches
yourself or should I resend a new version?)
Thanks!
Christian

Fixed.
(Yeah, though it doesn't really matter as the error would lead to the
mount namespace being unuseable and you'd see this pretty glaringly not
just in terms of behavior but also in terms of the output in 631.out.)

Yeah, I think even without that check I can just directly use
_filter_quota_report. Not sure why I didn't use it right away. Probably
an oversight on my part that it was available as a generic helper.
Thanks for the pointer.

I've added this as a simpler helper in its current form with the ability
to map a single id for now. We can later add a more complex helper if we
need to but handling variable number of arguments isn't really pleasant
so I'd defer this part until we need it.

We don't need the lazy umount. I just use this as my default umount
strategy.
