git://git.kernel.org/pub/scm/linux/kernel/git/gfs2/linux-gfs2
Pull gfs2 updates from Bob Peterson:
"We've got ten patches this time, half of which are related to a
plethora of nasty outcomes when inodes are transitioned from the
unlinked state to the free state. Small file systems are particularly
vulnerable to these problems, and it can manifest as mainly hangs, but
also file system corruption. The patches have been tested for
literally many weeks, with a very gruelling test, so I have a high
level of confidence.
- Andreas Gruenbacher wrote a series of five patches for various
lockups during the transition of inodes from unlinked to free.
The main patch is titled "Fix gfs2_lookup_by_inum lock inversion"
and the other four are support and cleanup patches related to that.
- Ben Marzinski contributed two patches with regard to a recreatable
problem when gfs2 tries to write a page to a file that is being
truncated, resulting in a BUG() in gfs2_remove_from_journal.
Note that Ben had to export vfs function __block_write_full_page to
get this to work properly. It's been posted a long time and he
talked to various VFS people about it, and nobody seemed to mind.
- I contributed 3 patches:
o The first one fixes a memory corruptor: a race in which one
process can overwrite the gl_object pointer set by another
process, causing kernel panic and other symptoms.
o The second patch fixes another race that resulted in a
false-positive BUG_ON. This occurred when resource group
reservations were freed by one process while another process
was trying to grab a new reservation in the same resource
group.
o The third patch fixes a problem with doing journal replay when
the journals are not all the same size"

When a latent (unknown to 'badblocks') error is encountered, it will
trigger a machine check exception. On a system with machine check
recovery, this will only SIGBUS the process(es) which had the bad page
mapped (as opposed to a kernel panic on platforms without machine
check recovery features). In the former case, we want to trigger a full
rescan of that nvdimm bus. This will allow any additional, new errors
to be captured in the block devices' badblocks lists, and offending
operations on them can be trapped early, avoiding machine checks.
This is done by registering a callback function with the
x86_mce_decoder_chain and calling the new ars_rescan functionality with
the address in the mce notificatiion.

Normally, an ARS (Address Range Scrub) only happens at
boot/initialization time. There can however arise situations where a
bus-wide rescan is needed - notably, in the case of discovering a latent
media error, we should do a full rescan to figure out what other sectors
are bad, and thus potentially avoid triggering an mce on them in the
future. Also provide a sysfs trigger to start a bus-wide scrub.

Seth Forshee reported a mount regression in nfs autmounts
with "fs: Add user namespace member to struct super_block".
It turns out that the assumption that current->cred is something
reasonable during mount while necessary to improve support of
unprivileged mounts is wrong in the automount path.
To fix the existing filesystems override current->cred with the
init_cred before calling d_automount and restore current->cred after
d_automount completes.
To support unprivileged mounts would require a more nuanced cred
selection, so fail on unprivileged mounts for the time being. As none
of the filesystems that currently set FS_USERNS_MOUNT implement
d_automount this check is only good for preventing future problems.

Valdis Kletnieks bisected a boot failure back to this recent commit:
360cb4d15567 ("x86/mm/cpa: In populate_pgd(), don't set the PGD entry until it's populated")
I broke the case where a PUD table got allocated -- populate_pud()
would wander off a pgd_none entry and get lost. I'm not sure how
this survived my testing.
Fix the original issue in a much simpler way. The problem
was that, if we allocated a PUD table, failed to populate it, and
freed it, another CPU could potentially keep using the PGD entry we
installed (either by copying it via vmalloc_fault or by speculatively
caching it). There's a straightforward fix: simply leave the
top-level entry in place if this happens. This can't waste any
significant amount of memory -- there are at most 256 entries like
this systemwide and, as a practical matter, if we hit this failure
path repeatedly, we're likely to reuse the same page anyway.
For context, this is a reversion with this hunk added in:
if (ret < 0) {
+ /*
+ * Leave the PUD page in place in case some other CPU or thread
+ * already found it, but remove any useless entries we just
+ * added to it.
+ */
- unmap_pgd_range(cpa->pgd, addr,
+ unmap_pud_range(pgd_entry, addr,
addr + (cpa->numpages << PAGE_SHIFT));
return ret;
}
This effectively open-codes what the now-deleted unmap_pgd_range()
function used to do except that unmap_pgd_range() used to try to
free the page as well.

A recent effort to add a new nvdimm bus provider attribute highlighted a
race between interrogating nvdimm_bus->nd_desc and nvdimm_bus tear down.
The typical way to handle these races is to take the device_lock() in
the attribute method and validate that the device is still active. In
order for a device to be 'active' it needs to be associated with a
driver. So, we create the small boilerplate for a driver and register
nvdimm_bus devices on the 'nvdimm_bus_type' bus.
A result of this change is that ndbusX devices now appear under
/sys/bus/nd/devices. In fact this makes /sys/class/nd somewhat
redundant, but removing that will need to take a long deprecation period
given its use by ndctl binaries in the field.
This change naturally pulls code from drivers/nvdimm/core.c to
drivers/nvdimm/bus.c, so it is a nice code organization clean-up as
well.
