Call graph of vfs_get_tree():
vfs_fsconfig_locked() # neither kernmount, nor submount
do_new_mount() # neither kernmount, nor submount
fc_mount()
afs_mntpt_do_automount() # submount
mount_one_hugetlbfs() # kernmount

init_mount_tree()
btrfs_mount()
nfs_do_root_mount()
The first two need the check (unconditionally).
init_mount_tree() is setting rootfs up; any capability
checks make zero sense for that one. And btrfs_mount()/
nfs_do_root_mount() have the checks already done in their
callers.
IOW, we can shift mount_capable() handling into
the two callers - one in the normal case of mount(2),
another - in fsconfig(2) handling of FSCONFIG_CMD_CREATE.
I.e. the syscalls that set a new filesystem up.

sget_fc() is called only from ->get_tree() instances and
the only instance not calling it is legacy_get_tree(),
which calls mount_capable() directly.
In all sget_fc() callers the checks could be moved to the
very beginning of ->get_tree() - ->user_ns is not changed
in between. So lifting the checks to the only caller of
->get_tree() is OK.
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
now both callers of mount_capable() have access to fs_context;
the only difference is that for sget_fc() we have the possibility
of fc->global being true, while for legacy_get_tree() it's guaranteed
to be impossible. Unify to more generic variant...
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
guaranteed to be equal to current_user_ns() here - it has not
been changed since alloc_fs_context() (nothing in legacy
methods changes it) and since we don't have SB_SUBMOUNT,
that must've been FS_CONTEXT_FOR_MOUNT. And in that case
we have fc->user_ns set to fc->cred->user_ns, i.e.
current_cred()->user_ns, i.e. current_user_ns()
Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
1) all call chains leading to sget_userns() pass through ->mount()
instances.
2) none of ->mount() instances is ever called directly - the only
call site is legacy_get_tree()
3) all remaining ->mount() instances end up calling sget_userns()
IOW, we might as well do the capability checks just before calling
->mount(). As for the arguments passed to mount_capable(),
in case of call chains to sget_userns() going through sget(),
we either don't call mount_capable() at all, or pass current_user_ns()
to it. The call chains going through mount_pseudo_xattr() don't
call mount_capable() at all (SB_KERNMOUNT in flags on those).
That could've been split into smaller steps (lifting the checks
into sget(), then callers of sget(), then all the way to the
entries of every ->mount() out there, then to the sole caller),
but that would be too much churn for little benefit...

there are 3 remaining callers of sget_userns() - sget(), mount_ns()
and mount_pseudo_xattr(). Extra check in sget() is conditional
upon mount being neither KERNMOUNT nor SUBMOUNT, the identical one
in mount_ns() - upon being not KERNMOUNT; mount_pseudo_xattr()
has no such checks at all.
However, mount_ns() is never used with SUBMOUNT and mount_pseudo_xattr()
is used only for KERNMOUNT, so both would be fine with the same logics
as currently done in sget(), allowing to consolidate the entire thing
in sget_userns() itself.
That's not where these checks will end up in the long run, though -
the whole reason why they'd been done so deep in the bowels of
mount(2) was that there had been no way for a filesystem to specify
which userns to look at until it has entered ->mount().
Now there is a place where filesystem could override the defaults -
->init_fs_context(). Which allows to pull the checks out into
the callers of vfs_get_tree(). That'll take quite a bit of
massage, but that mess is possible to tease apart.

Once upon a time we used to set ->d_name of e.g. pipefs root
so that d_path() on pipes would work. These days it's
completely pointless - dentries of pipes are not even connected
to pipefs root. However, mount_pseudo() had set the root
dentry name (passed as the second argument) and callers
kept inventing names to pass to it. Including those that
didn't *have* any non-root dentries to start with...
All of that had been pointless for about 8 years now; it's

As Ju Hyung reported:
"
I was semi-forced today to use the new kernel and test f2fs.
My Ubuntu initramfs got a bit wonky and I had to boot into live CD and
fix some stuffs. The live CD was using 4.15 kernel, and just mounting
the f2fs partition there corrupted f2fs and my 4.19(with 5.1-rc1-4.19
f2fs-stable merged) refused to mount with "SIT is corrupted node"
message.
I used the latest f2fs-tools sent by Chao including "fsck.f2fs: fix to
repair cp_loads blocks at correct position"
It spit out 140M worth of output, but at least I didn't have to run it
twice. Everything returned "Ok" in the 2nd run.
The new log is at
http://arter97.com/f2fs/final
After fixing the image, I used my 4.19 kernel with 5.2-rc1-4.19
f2fs-stable merged and it mounted.
But, I got this:
[ 1.047791] F2FS-fs (nvme0n1p3): layout of large_nat_bitmap is
deprecated, run fsck to repair, chksum_offset: 4092

[ 1.162418] F2FS-fs (nvme0n1p3): Mounted with checkpoint version = 761c7e00
But after doing a reboot, the message is gone:
[ 1.098423] F2FS-fs (nvme0n1p3): Found nat_bits in checkpoint

[ 1.178365] F2FS-fs (nvme0n1p3): Mounted with checkpoint version = 761c7eda
I'm not exactly sure why the kernel detected that I'm still using the
old layout on the first boot. Maybe fsck didn't fix it properly, or
the check from the kernel is improper.
"
Although we have rebuild the old deprecated checkpoint with new layout
during repair, we only repair last checkpoint park, the other old one is
remained.
Once the image was mounted, we will 1) sanity check layout and 2) decide
which checkpoint park to use according to cp_ver. So that we will print
reported message unnecessarily at step 1), to avoid it, we simply move
layout check into f2fs_sanity_check_ckpt() after step 2).

"Here is a series of patches that add SPDX tags to different kernel

- SPDX entries are added to a bunch of files that we missed a year
ago that do not have any license information at all.
These were either missed because the tool saw the MODULE_LICENSE()
tag, or some EXPORT_SYMBOL tags, and got confused and thought the
file had a real license, or the files have been added since the
last big sweep, or they were Makefile/Kconfig files, which we
didn't touch last time.
- Add GPL-2.0-only or GPL-2.0-or-later tags to files where our scan
tools can determine the license text in the file itself. Where this
happens, the license text is removed, in order to cut down on the
700+ different ways we have in the kernel today, in a quest to get

list, and while they were created by automatic tools, they were
hand-verified by a bunch of different people, all whom names are on
the patches are reviewers.
The reason for these "large" patches is if we were to continue to
progress at the current rate of change in the kernel, adding license
tags to individual files in different subsystems, we would be finished
in about 10 years at the earliest.
There will be more series of these types of patches coming over the
next few weeks as the tools and reviewers crunch through the more
"odd" variants of how to say "GPLv2" that developers have come up with
over the years, combined with other fun oddities (GPL + a BSD
disclaimer?) that are being unearthed, with the goal for the whole
kernel to be cleaned up.
These diffstats are not small, 3840 files are touched, over 10k lines
removed in just 24 patches"
