In 9dbbfb0ab6680c6a85609041011484e6658e7d3c function tipc_sk_reinit
had additional logic added to loop in the event that function
rhashtable_walk_next() returned -EAGAIN. No worries.
However, if rhashtable_walk_start returns -EAGAIN, it does "continue",
and therefore skips the call to rhashtable_walk_stop(). That has
the effect of calling rcu_read_lock() without its paired call to
rcu_read_unlock(). Since rcu_read_lock() may be nested, the problem
may not be apparent for a while, especially since resize events may
be rare. But the comments to rhashtable_walk_start() state:
* ...Note that we take the RCU lock in all
* cases including when we return an error. So you must always call
* rhashtable_walk_stop to clean up.
This patch replaces the continue with a goto and label to ensure a
matching call to rhashtable_walk_stop().

gcc-8.0.0 (snapshot) points out that we copy a variable-length string
into a fixed length field using memcpy() with the destination length,
and that ends up copying whatever follows the string:
inlined from 'ql_core_dump' at drivers/net/ethernet/qlogic/qlge/qlge_dbg.c:1106:2:
drivers/net/ethernet/qlogic/qlge/qlge_dbg.c:708:2: error: 'memcpy' reading 15 bytes from a region of size 14 [-Werror=stringop-overflow=]
memcpy(seg_hdr->description, desc, (sizeof(seg_hdr->description)) - 1);
Changing it to use strncpy() will instead zero-pad the destination,
which seems to be the right thing to do here.
The bug is probably harmless, but it seems like a good idea to address
it in stable kernels as well, if only for the purpose of building with
gcc-8 without warnings.

The implementation of TIOCGPTPEER has two issues.
When /dev/ptmx (as opposed to /dev/pts/ptmx) is opened the wrong
vfsmount is passed to dentry_open. Which results in the kernel displaying
the wrong pathname for the peer.
The second is simply by caching the vfsmount and dentry of the peer it leaves
them open, in a way they were not previously Which because of the inreased
reference counts can cause unnecessary behaviour differences resulting in
regressions.
To fix these move the ioctl into tty_io.c at a generic level allowing
the ioctl to have access to the struct file on which the ioctl is
being called. This allows the path of the slave to be derived when
opening the slave through TIOCGPTPEER instead of requiring the path to
the slave be cached. Thus removing the need for caching the path.
A new function devpts_ptmx_path is factored out of devpts_acquire and
used to implement a function devpts_mntget. The new function devpts_mntget
takes a filp to perform the lookup on and fsi so that it can confirm
that the superblock that is found by devpts_ptmx_path is the proper superblock.
v2: Lots of fixes to make the code actually work
v3: Suggestions by Linus
- Removed the unnecessary initialization of filp in ptm_open_peer
- Simplified devpts_ptmx_path as gotos are no longer required
[ This is the fix for the issue that was reverted in commit
143c97cc6529, but this time without breaking 'pbuilder' due to
increased reference counts - Linus ]

Commit 0a987645672e ("um: Allow building and running on older
hosts") attempted to check for PTRACE_{GET,SET}REGSET under the premise
that these ptrace(2) parameters were directly linked with the presence
of the _xstate structure.
After Richard's commit 61e8d462457f ("um: Correctly check for
PTRACE_GETRESET/SETREGSET") which properly included linux/ptrace.h
instead of asm/ptrace.h, we could get into the original build failure
that I reported:
arch/x86/um/user-offsets.c: In function 'foo':
arch/x86/um/user-offsets.c:54: error: invalid application of 'sizeof' to
incomplete type 'struct _xstate'
On this particular host, we do have PTRACE_GETREGSET and
PTRACE_SETREGSET defined in linux/ptrace.h, but not the structure
_xstate that should be pulled from the following include chain: signal.h
-> bits/sigcontext.h.
Correctly fix this by checking for FP_XSTATE_MAGIC1 which is the correct
way to see if struct _xstate is available or not on the host.

Commit 44c58487d51a ("IB/core: Define 'ib' and 'roce' rdma_ah_attr types")
introduced the concept of type in ah_attr:
* During ib_register_device, each port is checked for its type which
is stored in ib_device's port_immutable array.
* During uverbs' modify_qp, the type is inferred using the port number
in ib_uverbs_qp_dest struct (address vector) by accessing the
relevant port_immutable array and the type is passed on to
providers.
IB spec (version 1.3) enforces a valid port value only in Reset to
Init. During Init to RTR, the address vector must be valid but port
number is not mentioned as a field in the address vector, so its
value is not validated, which leads to accesses to a non-allocated
memory when inferring the port type.
Save the real port number in ib_qp during modify to Init (when the
comp_mask indicates that the port number is valid) and use this value
to infer the port type.
Avoid copying the address vector fields if the matching bit is not set
in the attr_mask. Address vector can't be modified before the port, so
no valid flow is affected.

I guess the nested numbering in:
./input/joydev/index.rst
./media/uapi/cec/cec-funcs.rst
is just a C&P typo, so lets remove it.

Currently, on Sphinx up to version 1.4, pdf output uses a vertical
margin of 1 inch. For upper versions, it uses a margin of 0.5 inches.
That causes both page headers and footers to be very close to the margin
of the sheet. Not all printers support writing like that.
Also, there's no reason why the layout for newer versions would be
different than for previous ones.
So, standardize it, by always setting to 1 inch.

Right now, if the building system doesn't find Sphinx, it
bails out, without providing any instructions about what

Instead, run a script, providing some guidance about the
steps needed for Sphinx build to work.

====================
Netfilter fixes for net
The following patchset contains Netfilter fixes for your net tree,
they are:
1) Fix use after free of struct proc_dir_entry in ipt_CLUSTERIP, patch
from Sabrina Dubroca.
2) Fix spurious EINVAL errors from iptables over nft compatibility layer.
3) Reload pointer to ip header only if there is non-terminal verdict,
ie. XT_CONTINUE, otherwise invalid memory access may happen, patch
from Taehee Yoo.
4) Fix interaction between SYNPROXY and NAT, SYNPROXY adds sequence
adjustment already, however from nf_nat_setup() assumes there's not.
Patch from Xin Long.
5) Fix burst arithmetics in nft_limit as Joe Stringer mentioned during
NFWS in Faro. Patch from Andy Zhou.
