fs/pipe.c: return error code rather than 0 in pipe_write()
pipe_write() would return 0 if it failed to merge the beginning of the

return an error code instead. Userspace programs could be confused by
write() returning 0 when called with a nonzero 'count'.

older bug.

fs/pipe.c: preserve alloc_file() error code
If sys_pipe() was unable to allocate a 'struct file', it always failed
with ENFILE, which means "The number of simultaneously open files in the
system would exceed a system-imposed limit." However, alloc_file()
actually returns an ERR_PTR value and might fail with other error codes.
Currently, in addition to ENFILE, it can fail with ENOMEM, potentially
when there are few open files in the system. Update sys_pipe() to
preserve this error code.
In a prior submission of a similar patch (1) some concern was raised
about introducing a new error code for sys_pipe(). However, for most
system calls, programs cannot assume that new error codes will never be
introduced. In addition, ENOMEM was, in fact, already a possible error
code for sys_pipe(), in the case where the file descriptor table could
not be expanded due to insufficient memory.

binfmt_elf: Don't clobber passed executable's file header
Do not clobber the buffer space passed from `search_binary_handler' and
originally preloaded by `prepare_binprm' with the executable's file
header by overwriting it with its interpreter's file header. Instead
keep the buffer space intact and directly use the data structure locally
allocated for the interpreter's file header, fixing a bug introduced in
2.1.14 with loadable module support (linux-mips.org commit
beb11695
[Import of Linux/MIPS 2.1.14], predating kernel.org repo's history).
Adjust the amount of data read from the interpreter's file accordingly.
This was not an issue before loadable module support, because back then
`load_elf_binary' was executed only once for a given ELF executable,
whether the function succeeded or failed.
With loadable module support supported and enabled, upon a failure of
`load_elf_binary' -- which may for example be caused by architecture
code rejecting an executable due to a missing hardware feature requested
in the file header -- a module load is attempted and then the function
reexecuted by `search_binary_handler'. With the executable's file
header replaced with its interpreter's file header the executable can
then be erroneously accepted in this subsequent attempt.

FS-Cache: Handle a write to the page immediately beyond the EOF marker
Handle a write being requested to the page immediately beyond the EOF
marker on a cache object. Currently this gets an assertion failure in
CacheFiles because the EOF marker is used there to encode information about
a partial page at the EOF - which could lead to an unknown blank spot in
the file if we extend the file over it.
The problem is actually in fscache where we check the index of the page
being written against store_limit. store_limit is set to the number of
pages that we're allowed to store by fscache_set_store_limit() - which
means it's one more than the index of the last page we're allowed to store.
The problem is that we permit writing to a page with an index _equal_ to
the store limit - when we should reject that case.
Whilst we're at it, change the triggered assertion in CacheFiles to just
return -ENOBUFS instead.
The assertion failure looks something like this:
CacheFiles: Assertion failed
1000 < 7b1 is false

However, when we run into an error during lookup_one_len() when still

drivers: of: of_reserved_mem: fixup the alignment with CMA setup
There is an alignment mismatch issue between the of_reserved_mem and
the CMA setup requirement. The of_reserved_mem will try to get the
alignment value from the DTS and pass it to __memblock_alloc_base to
do the memory block base allocation, but the alignment value specified
in the DTS may not satisfy the CAM setup requirement since CMA setup
required the alignment as the following in the code:
align = PAGE_SIZE << max(MAX_ORDER - 1, pageblock_order);
The sanity check in the function of rmem_cma_setup will fail if the
alignment does not setup correctly and thus CMA will fail to setup.
This patch is to fixup the alignment to meet the CMA setup required.

of: Print rather than WARN'ing when overlap check fails
__rmem_check_for_overlap() is called very early in boot, and on some
powerpc systems it's not safe to call WARN that early in boot.
If the overlap check fails the system will oops instead of printing a
warning. Furthermore because it's so early in boot the console is not up

used to communicate with the assistant embedded cores doing power
management, and we have yet to see how many of them will implement
this for their hardware vs abstracting in other ways (or not at all

Fix alloc_node_mem_map() to work on ia64 again
In commit
a1c34a3bf00a ("mm: Don't offset memmap for flatmem") Laura
fixed a problem for Srinivas relating to the bottom 2MB of RAM on an ARM
IFC6410 board.
One small wrinkle on ia64 is that it allocates the node_mem_map earlier
in arch code, so it skips the block of code where "offset" is
initialized.
Move initialization of start and offset before the check for the
node_mem_map so that they will always be available in the latter part of
the function.

This reverts commit
34c2d9fb0498c066afbe610b15e18995fd8be792.
There are 2 reasons for this revert:
1) The commit in question doesn't do what it says it does. The
description reads: "Allow bridge forward delay to be configured
when Spanning Tree is enabled." This was already the case before
the commit was made. What the commit actually do was disallow
invalid values or 'forward_delay' when STP was turned off.
2) The above change was actually a change in the user observed
behavior and broke things like libvirt and other network configs
that set 'forward_delay' to 0 without enabling STP. The value
of 0 is actually used when STP is turned off to immediately mark
the bridge as forwarding.

bpf_trace: Make dependent on PERF_EVENTS

This can happen when UPROBE_EVENT is enabled but KPROBE_EVENT
is disabled. I'm not sure if that is a configuration we care
about, otherwise we could prevent this case from occuring by
adding Kconfig dependencies.
Looking at this further, it's really that UPROBE_EVENT enables PERF_EVENTS.
By just having BPF_EVENTS depend on PERF_EVENTS, then all is fine.

nfsd: fix race with open / open upgrade stateids
We observed multiple open stateids on the server for files that
seemingly should have been closed.
nfsd4_process_open2() tests for the existence of a preexisting
stateid. If one is not found, the locks are dropped and a new
one is created. The problem is that init_open_stateid(), which
is also responsible for hashing the newly initialized stateid,
doesn't check to see if another open has raced in and created
a matching stateid. This fix is to enable init_open_stateid() to
return the matching stateid and have nfsd4_process_open2()
swap to that stateid and switch to the open upgrade path.
In testing this patch, coverage to the newly created
path indicates that the race was indeed happening.

nfsd: eliminate sending duplicate and repeated delegations
We've observed the nfsd server in a state where there are
multiple delegations on the same nfs4_file for the same client.
The nfs client does attempt to DELEGRETURN these when they are presented to
it - but apparently under some (unknown) circumstances the client does not
manage to return all of them. This leads to the eventual
attempt to CB_RECALL more than one delegation with the same nfs
filehandle to the same client. The first recall will succeed, but the
next recall will fail with NFS4ERR_BADHANDLE. This leads to the server
having delegations on cl_revoked that the client has no way to FREE
or DELEGRETURN, with resulting inability to recover. The state manager
on the server will continually assert SEQ4_STATUS_RECALLABLE_STATE_REVOKED,
and the state manager on the client will be looping unable to satisfy
the server.
List discussion also reports a race between OPEN and DELEGRETURN that
will be avoided by only sending the delegation once to the
client. This is also logically in accordance with RFC5561 9.1.1 and 10.2.
So, let's:
1.) Not hand out duplicate delegations.
2.) Only send them to the client once.
RFC 5561:
9.1.1:
"Delegations and layouts, on the other hand, are not associated with a
specific owner but are associated with the client as a whole
(identified by a client ID)."
10.2:
"...the stateid for a delegation is associated with a client ID and may be
used on behalf of all the open-owners for the given client. A
delegation is made to the client as a whole and not to any specific
process or thread of control within it."

Pull parisc updates from Helge Deller:
"We have two patches in here:
- The parisc uapi headers have been screwed up since quite some time.
This patch fixes some bugs (e.g. endianess not respected in
compat_semid64_ds) and cleans them up (e.g. uid_t was used instead
of __kernel_uid_t) so that they can be used by userspace again.
This patch has been reviewed by Arnd Bergmann and is scheduled for
stable kernel series.
- Drop the hpux_stat64 struct from stat.h, we do not support HP-UX
binaries since kernel 4.0"
