====================
rxrpc: Preparation for removal of use of skbs from AFS
Here's a set of patches that prepare the way for the removal of the use of
sk_buffs from fs/afs (they'll be entirely retained within net/rxrpc):
(1) Fix a potential NULL-pointer deref in rxrpc_abort_calls().
(2) Condense all the terminal call state machine states to a single one
plus supplementary info.
(3) Add a trace point for rxrpc call usage debugging.
(4) Cleanups and missing headers.
(5) Provide a way for AFS to ask about a call's peer address without
having an sk_buff to query.
(6) Use call->peer directly rather than going via call->conn (which might
be NULL).
(7) Pass struct socket * to various rxrpc kernel interface functions so
they can use that directly rather than getting it from the rxrpc_call
struct.

Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree,
they are:
1) Allow nf_tables reject expression from input, forward and output hooks,
since only there the routing information is available, otherwise we crash.
2) Fix unsafe list iteration when flushing timeout and accouting objects.
3) Fix refcount leak on timeout policy parsing failure.
4) Unlink timeout object for unconfirmed conntracks too
5) Missing validation of pkttype mangling from bridge family.
6) Fix refcount leak on ebtables on second lookup for the specific
bridge match extension, this patch from Sabrina Dubroca.
7) Remove unnecessary ip_hdr() in nf_tables_netdev family.

Three little fixes:
* revert a recent wext patch, which Ben Hutchings noticed was
wrong, and it turns out not to be necessary for any driver
* fix an infinite loop that can occur under certain conditions

The workqueue "dm_bufio_wq" queues a single work item &dm_bufio_work so
it doesn't require execution ordering. Hence, alloc_workqueue() has
been used to replace the deprecated create_singlethread_workqueue().
The WQ_MEM_RECLAIM flag has been set since DM requires forward progress
under memory pressure.
Since there are fixed number of work items, explicit concurrency
limit is unnecessary here.

If crypt_alloc_tfms() had to allocate multiple tfms and it failed before
the last allocation, then it would call crypt_free_tfms() and could free

When dm-crypt processes writes, it allocates a new bio in
crypt_alloc_buffer(). The bio is allocated from a bio set and it can
have at most BIO_MAX_PAGES vector entries, however the incoming bio can be
larger (e.g. if it was allocated by bcache). If the incoming bio is
larger, bio_alloc_bioset() fails and an error is returned.
To avoid the error, we test for a too large bio in the function
crypt_map() and use dm_accept_partial_bio() to split the bio.
dm_accept_partial_bio() trims the current bio to the desired size and
asks DM core to send another bio with the rest of the data.

Pull seccomp fix from Kees Cook:
"Fix fatal signal delivery after ptrace reordering"
* tag 'seccomp-v4.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
seccomp: Fix tracer exit notifications during fatal signals
|
|
This fixes a ptrace vs fatal pending signals bug as manifested in
seccomp now that seccomp was reordered to happen after ptrace. The
short version is that seccomp should not attempt to call do_exit()
while fatal signals are pending under a tracer. The existing code was
trying to be as defensively paranoid as possible, but it now ends up
confusing ptrace. Instead, the syscall can just be skipped (which solves
the original concern that the do_exit() was addressing) and normal signal
handling, tracer notification, and process death can happen.
Paraphrasing from the original bug report:
If a tracee task is in a PTRACE_EVENT_SECCOMP trap, or has been resumed
after such a trap but not yet been scheduled, and another task in the
thread-group calls exit_group(), then the tracee task exits without the
ptracer receiving a PTRACE_EVENT_EXIT notification. Test case here:
https://gist.github.com/khuey/3c43ac247c72cef8c956ca73281c9be7
The bug happens because when __seccomp_filter() detects
fatal_signal_pending(), it calls do_exit() without dequeuing the fatal
signal. When do_exit() sends the PTRACE_EVENT_EXIT notification and
that task is descheduled, __schedule() notices that there is a fatal
signal pending and changes its state from TASK_TRACED to TASK_RUNNING.
That prevents the ptracer's waitpid() from returning the ptrace event.
A more detailed analysis is here:
https://github.com/mozilla/rr/issues/1762#issuecomment-237396255.

bio_alloc() can allocate a bio with at most BIO_MAX_PAGES (256) vector
entries. However, the incoming bio may have more vector entries if it
was allocated by other means. For example, bcache submits bios with
more than BIO_MAX_PAGES entries. This results in bio_alloc() failure.
To avoid the failure, change the code so that it allocates bio with at
most BIO_MAX_PAGES entries. If the incoming bio has more entries,
bio_add_page() will fail and a new bio will be allocated - the code that
handles bio_add_page() failure already exists in the dm-log-writes
target.

fix a bug that the target hangs if bio_alloc() fails. The error path
does put_io_block(lc), so atomic_inc(&lc->io_blocks) must occur before
invoking the error path to avoid underflow of lc->io_blocks.

There are three usercopy warnings which are currently being silenced for
gcc 4.6 and newer:
1) "copy_from_user() buffer size is too small" compile warning/error
This is a static warning which happens when object size and copy size
are both const, and copy size > object size. I didn't see any false
positives for this one. So the function warning attribute seems to
be working fine here.
Note this scenario is always a bug and so I think it should be
changed to *always* be an error, regardless of
CONFIG_DEBUG_STRICT_USER_COPY_CHECKS.
2) "copy_from_user() buffer size is not provably correct" compile warning
This is another static warning which happens when I enable
__compiletime_object_size() for new compilers (and
CONFIG_DEBUG_STRICT_USER_COPY_CHECKS). It happens when object size
is const, but copy size is *not*. In this case there's no way to
compare the two at build time, so it gives the warning. (Note the
warning is a byproduct of the fact that gcc has no way of knowing
whether the overflow function will be called, so the call isn't dead
code and the warning attribute is activated.)
So this warning seems to only indicate "this is an unusual pattern,
maybe you should check it out" rather than "this is a bug".
I get 102(!) of these warnings with allyesconfig and the
__compiletime_object_size() gcc check removed. I don't know if there
are any real bugs hiding in there, but from looking at a small
sample, I didn't see any. According to Kees, it does sometimes find
real bugs. But the false positive rate seems high.
3) "Buffer overflow detected" runtime warning
This is a runtime warning where object size is const, and copy size >
object size.
All three warnings (both static and runtime) were completely disabled
for gcc 4.6 with the following commit:
2fb0815c9ee6 ("gcc4: disable __compiletime_object_size for GCC 4.6+")
That commit mistakenly assumed that the false positives were caused by a
gcc bug in __compiletime_object_size(). But in fact,
__compiletime_object_size() seems to be working fine. The false
positives were instead triggered by #2 above. (Though I don't have an
explanation for why the warnings supposedly only started showing up in
gcc 4.6.)
So remove warning #2 to get rid of all the false positives, and re-enable
warnings #1 and #3 by reverting the above commit.
Furthermore, since #1 is a real bug which is detected at compile time,
upgrade it to always be an error.
Having done all that, CONFIG_DEBUG_STRICT_USER_COPY_CHECKS is no longer
needed.

and reduction of read locking section, all the reported locking
latency issues, including the android one, are resolved.

In the future the kernel service won't get sk_buffs to look inside.
Further, this allows us to hide any canonicalisation inside AF_RXRPC for

Also propagate this through to afs_find_server() and issue a warning if we

i.MX6SX has bypass PMIC ready function, as this function
is normally NOT enabled on the board design, so we need
to bypass the PMIC ready pin check during DSM mode resume
flow, otherwise, the internal DSM resume logic will be
waiting for this signal to be ready forever and cause
resume fail.

If device family is 8000 then iwl_pcie_load_cpu_sections()
won't be called at all (iwl_pcie_load_cpu_sections_8000() is
called in that case) so this piece of code never gets called.

Turns out we should access TFH relative addresses.
Also, the FH_UCODE_LOAD_STATUS was replaced by
UREG_UCODE_LOAD_STATUS.

Up till now we accessed SCD configuration only for initial
configuration and for enabling command queue.
For a000 generation the command queue is open by default
and firmware configures the rest. No driver SCD accesses
are expected. Make sure this is the case.

Every active TXQ is assigned to a TID given through the
SCD_CONFIG_CMD, and acts as an identifier in the FW. However,
there may be cases this ownership needs to be changed.
For example, in the following scenario:
1. TID x is owner of a queue
2. Due to a shortage of queues, TID y and z share with x
3. TID x becomes inactive and needs to be removed from the
shared queue.
In this scenario, if another queue is freed and traffic on x
continues, we can't allocate it a new queue as long as it is
the owner of the first queue.
Support moving ownership of a TXQ to a different TID (same
STA) without stopping the queue.

Due to the addition of another option in the SCD_CONFIG_CMD's
%enable field, change the assignment of this field to use
defines rather than hard-code the value itself.

When working in DQA mode, if a queue is shared and a HW restart
occurs, there might be a possible race condition between
stations on the queues, and an existing queue might be left
with no queues.
To solve this, make sure in DQA mode to re-assign the same
queues as before the HW restart.

When sending the SCD_QUEUE_CONFIG command, the queue is
associated to a specific TID. If later there is a need to
use this TID on a different queue instead, it first needs to
be unassociated from the first queue.
Keep track for every queue what TID is associated with it.

When a shared queue becomes unshared, aggregations should be
re-enabled if they've existed before. Make sure that they do
this, if required.
