bio integrity handling is broken on a system with LVM layered atop a
DIF/DIX SCSI drive because device mapper clones the bio, modifies the
clone, and sends the clone to the lower layers for processing.
However, the clone bio has bi_vcnt == 0, which means that when the sd
driver calls bio_integrity_process to attach DIX data, the
for_each_segment_all() call (which uses bi_vcnt) returns immediately
and random garbage is sent to the disk on a disk write. The disk of
course returns an error.
Therefore, teach bio_integrity_process() to use bio_for_each_segment()
to iterate the bio_vecs, since the per-bio iterator tracks which
bio_vecs are associated with that particular bio. The integrity
handling code is effectively part of the "driver" (it's not the bio
owner), so it must use the correct iterator function.
v2: Fix a compiler warning about abandoned local variables. This
patch supersedes "block: bio_integrity_process uses wrong bio_vec
iterator". Patch applies against 3.18-rc6.

Apparently PCH fifo underruns are tricky, we have plenty reports that
we see the occasional underrun (especially at boot-up).
So for a change let's see what happens when we don't re-enable pch
fifo underrun reporting when the pipe is disabled. This means that the
kernel can't catch pch fifo underruns when they happen (except when
all pipes are on on the pch). But we'll still catch underruns when
disabling the pipe again. So not a terrible reduction in test
coverage.
Since the DRM_ERROR is new and hence a regression plan B would be to
revert it back to a debug output. Which would be a lot worse than this
hack for underrun test coverage in the wild. See the referenced
discussions for more.

git://anongit.freedesktop.org/git/nouveau/linux-2.6 into drm-fixes
Just a couple of fixes for the fallout from the fence rework.
* 'linux-3.18' of git://anongit.freedesktop.org/git/nouveau/linux-2.6:
drm/nouveau/gf116: remove copy1 engine
drm/nouveau: prevent stale fence->channel pointers, and protect with rcu
drm/nouveau/fifo/g84-: ack non-stall interrupt before handling it
|
|
Indications are that no GF116's actually have a copy engine there, but
actually have the decompression engine. This engine can be made to do
copies, but that should be done separately.
Unclear why this didn't turn up on all GF116's, but perhaps the
non-mobile ones came with enough VRAM to not trigger ttm migrations in
test scenarios.

* tag 'ext4_for_linus_urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4:
jbd2: fix regression where we fail to initialize checksum seed when loading
|
|
When we're enabling journal features, we cannot use the predicate
jbd2_journal_has_csum_v2or3() because we haven't yet set the sb
feature flag fields! Moreover, we just finished loading the shash
driver, so the test is unnecessary; calculate the seed always.
Without this patch, we fail to initialize the checksum seed the first
time we turn on journal_checksum, which means that all journal blocks
written during that first mount are corrupt. Transactions written
after the second mount will be fine, since the feature flag will be
set in the journal superblock. xfstests generic/{034,321,322} are the
regression tests.
(This is important for 3.18.)

Commit 0b0b0893d49b ("of/pci: Fix the conversion of IO ranges into IO
resources") changed how I/O resources are parsed from DT. Rather than
containing the physical address of the I/O region, the addresses will now
be in I/O address space.
On Tegra the union of all ranges is used to expose a top-level memory-
mapped resource for the PCI host bridge. This helps to make /proc/iomem
more readable.
Combining both of the above, the union would now include the I/O space
region. This causes a regression on Tegra20, where the physical base
address of the PCIe controller (and therefore of the union) is located at
physical address 0x80000000. Since I/O space starts at 0, the union will
now include all of system RAM which starts at 0x00000000.
This commit fixes this by keeping two copies of the I/O range: one that
represents the range in the CPU's physical address space, the other for the
range in the I/O address space. This allows the translation setup within
the driver to reuse the physical addresses. The code registering the I/O
region with the PCI core uses both ranges to establish the mapping.

Since the keyring facility can be viewed as a cache (at least in some
applications), the local expiration time on the key should probably be viewed
as a 'needs updating after this time' property rather than an absolute 'anyone
now wanting to use this object is out of luck' property.
Since request_key() is the main interface for the usage of keys, this should
update or replace an expired key rather than issuing EKEYEXPIRED if the local
expiration has been reached (ie. it should refresh the cache).
For absolute conditions where refreshing the cache probably doesn't help, the
key can be negatively instantiated using KEYCTL_REJECT_KEY with EKEYEXPIRED
given as the error to issue. This will still cause request_key() to return
EKEYEXPIRED as that was explicitly set.
In the future, if the key type has an update op available, we might want to
upcall with the expired key and allow the upcall to update it. We would pass
a different operation name (the first column in /etc/request-key.conf) to the
request-key program.
request_key() returning EKEYEXPIRED is causing an NFS problem which Chuck
Lever describes thusly:
After about 10 minutes, my NFSv4 functional tests fail because the
ownership of the test files goes to "-2". Looking at /proc/keys
shows that the id_resolv keys that map to my test user ID have
expired. The ownership problem persists until the expired keys are
purged from the keyring, and fresh keys are obtained.
I bisected the problem to 3.13 commit b2a4df200d57 ("KEYS: Expand
the capacity of a keyring"). This commit inadvertantly changes the
API contract of the internal function keyring_search_aux().
The root cause appears to be that b2a4df200d57 made "no state check"
the default behavior. "No state check" means the keyring search
iterator function skips checking the key's expiry timeout, and
returns expired keys. request_key_and_link() depends on getting
an -EAGAIN result code to know when to perform an upcall to refresh
an expired key.
This patch can be tested directly by:
keyctl request2 user debug:fred a @s
keyctl timeout %user:debug:fred 3
sleep 4
keyctl request2 user debug:fred a @s
Without the patch, the last command gives error EKEYEXPIRED, but with the
command it gives a new key.

Simplify KEYRING_SEARCH_{NO,DO}_STATE_CHECK flags to be two variations of the
same flag. They are effectively mutually exclusive and one or the other
should be provided, but not both.
Keyring cycle detection and key possession determination are the only things
that set NO_STATE_CHECK, except that neither flag really does anything there
because neither purpose makes use of the keyring_search_iterator() function,
but rather provides their own.
For cycle detection we definitely want to check inside of expired keyrings,
just so that we don't create a cycle we can't get rid of. Revoked keyrings
are cleared at revocation time and can't then be reused, so shouldn't be a
problem either way.
For possession determination, we *might* want to validate each keyring before
searching it: do you possess a key that's hidden behind an expired or just
plain inaccessible keyring? Currently, the answer is yes. Note that you
cannot, however, possess a key behind a revoked keyring because they are
cleared on revocation.
keyring_search() sets DO_STATE_CHECK, which is correct.
request_key_and_link() currently doesn't specify whether to check the key
state or not - but it should set DO_STATE_CHECK.
key_get_instantiation_authkey() also currently doesn't specify whether to
check the key state or not - but it probably should also set DO_STATE_CHECK.

When a key description argument is imported into the kernel from userspace, as
happens in add_key(), request_key(), KEYCTL_JOIN_SESSION_KEYRING,
KEYCTL_SEARCH, the description is copied into a buffer up to PAGE_SIZE in size.
PAGE_SIZE, however, is a variable quantity, depending on the arch. Fix this at
4096 instead (ie. 4095 plus a NUL termination) and define a constant
(KEY_MAX_DESC_SIZE) to this end.
When reading the description back with KEYCTL_DESCRIBE, a PAGE_SIZE internal
buffer is allocated into which the information and description will be
rendered. This means that the description will get truncated if an extremely
long description it has to be crammed into the buffer with the stringified
information. There is no particular need to copy the description into the
buffer, so just copy it directly to userspace in a separate operation.

First, there was this: https://bugzilla.kernel.org/show_bug.cgi?id=88001
The problem there was that microcode patches are not being reapplied
after suspend-to-ram. It was important to reapply them, though, because
of for example Haswell's TSX erratum which disabled TSX instructions
with a microcode patch.
A simple fix was fb86b97300d9 ("x86, microcode: Update BSPs microcode
on resume") but, as it is often the case, simple fixes are too
simple. This one causes 32-bit resume to fail:
https://bugzilla.kernel.org/show_bug.cgi?id=88391
Properly fixing this would require more involved changes for which it
is too late now, right before the merge window. Thus, limit this to
64-bit only temporarily.

Commit 0b8db271f159 ("ACPI / video: check _DOD list when creating

list to decide if we should create backlight device for it, that causes
problem for one Dell Latitude E6410, where none of the video output
devices are properly bound due to the way how we did the comparing
between its _ADR and the _DOD's values. Solve this problem by comparing
the lower 12 bits of both the device's _ADR and the _DOD's values instead
of relying on bind result.

There is a potential race when probing the TLB in TLBL/M/S exception
handlers for a matching entry. Between the time we hit a TLBL/S/M
exception and the time we get to execute the TLBP instruction, the
HTW may have replaced the TLB entry we are interested in hence the TLB
probe may fail. However, in the existing handlers, we never checked the
status of the TLBP (ie check the result in the C0/Index register). We
fix this by adding such a check when the core implements the HTW. If
we couldn't find a matching entry, we return back and try again.

We cannot restart cacheflush safely if a process provides user-defined
signal handler and signal is pending. In this case -EINTR is returned
and it is expected that process re-invokes syscall. However, there are
a few problems with that:
* looks like nobody bothers checking return value from cacheflush
* but if it did, we don't provide the restart address for that, so the
process has to use the same range again
* ...and again, what might lead to looping forever
So, remove cacheflush restarting code and terminate cache flushing
as early as fatal signal is pending.
