tcp: resets are misrouted
After commit
e2446eaa ("tcp_v4_send_reset: binding oif to iif in no
sock case").. tcp resets are always lost, when routing is asymmetric.
Yes, backing out that patch will result in misrouting of resets for
dead connections which used interface binding when were alive, but we
actually cannot do anything here. What's died that's died and correct
handling normal unbound connections is obviously a priority.
Comment to comment:
> This has few benefits:
> 1. tcp_v6_send_reset already did that.
It was done to route resets for IPv6 link local addresses. It was a
mistake to do so for global addresses. The patch fixes this as well.
Actually, the problem appears to be even more serious than guaranteed
loss of resets. As reported by Sergey Soloviev <sol@eqv.ru>, those
misrouted resets create a lot of arp traffic and huge amount of
unresolved arp entires putting down to knees NAT firewalls which use
asymmetric routing.

returns, that's because it has just done successful kernel_execve()

initially in my tree due to oversight.
The feature is for kdump kernels to speed up the /proc/vmcore reading.
There is a ram_is_pfn helper function that the different platforms can
register for. We are now doing that.
The bug-fixes cover some embarrassing struct pv_cpu_ops variables
being set to NULL on Xen (but not baremetal). We had a similar issue
in the past with {write|read}_msr_safe and this fills the three
missing ones. The other bug-fix is to make the console output (hvc)
be capable of dealing with misbehaving backends and not fall flat on
its face. Lastly, a quirk for older XenBus implementations that came
with an ancient v3.4 hypervisor (so RHEL5 based) - reading of certain
non-existent attributes just hangs the guest during bootup - so we
take precaution of not doing that on such older installations.
Feature:
- Register a pfn_is_ram helper to speed up reading of /proc/vmcore.
Bug-fixes:
- Three pvops call for Xen were undefined causing BUG_ONs.
- Add a quirk so that the shutdown watches (used by kdump) are not
used with older Xen (3.4).
- Fix ungraceful state transition for the HVC console."

The commit

"xen/pv-on-hvm kexec: shutdown watches from old kernel" assumes that the
XenBus backend can deal with reading of values from:
"control/platform-feature-xs_reset_watches":
... a patch for xenstored is required so that it
accepts the XS_RESET_WATCHES request from a client (see changeset
23839:
42a45baf037d in xen-unstable.hg). Without the patch for xenstored
the registration of watches will fail and some features of a PVonHVM
guest are not available. The guest is still able to boot, but repeated
kexec boots will fail."
Sadly this is not true when using a Xen 3.4 hypervisor and booting a PVHVM
guest. We end up hanging at:
err = xenbus_scanf(XBT_NIL, "control",
"platform-feature-xs_reset_watches", "%d", &supported);
This can easily be seen with guests hanging at xenbus_init:

It is possible to miss data when using the kdb pager. The kdb pager

correctly and the pager will print more lines that fit on the screen.
Obviously that is less than useful when using a VGA console where you

output ASCII that might move the cursor position, but it is a

First, it's incorrect to call putname() after __getname_gfp() since the
bare __getname_gfp() call skips the auditing code, while putname()
doesn't.
mount_block_root allocates a PATH_MAX buffer via __getname_gfp, and then
calls get_fs_names to fill the buffer. That function can call
get_filesystem_list which assumes that that buffer is a full page in
size. On arches where PAGE_SIZE != 4k, then this could potentially
overrun.
In practice, it's hard to imagine the list of filesystem names even
approaching 4k, but it's best to be safe. Just allocate a page for this

audit: remove unnecessary NULL ptr checks from do_path_lookup
As best I can tell, whenever retval == 0, nd->path.dentry and nd->inode
are also non-NULL. Eliminate those checks and the superfluous

Pull second set of media updates from Mauro Carvalho Chehab:
"Despite its size, most of the stuff here is trivial. This series
contains:
- s5p-mfc: additions at the driver and at the core to support H.264
hardware codec;
- Some improvements at s5p and davinci embedded drivers;
- Some V4L2 compliance fixes applied on a few drivers;
- Several random trivial patches, including several fixes and a few
new board support additions;
Notes:
1) Some Exynos media patches were dependent on some -arm fixes that
got merged on changeset 782cd9e. That's why this pull request is
based that changeset.
2) As promised, I reviewed the pending VB2 DMABUF series.
While setting a test environment, it was noticed that the upstream
support for Samsung Exynos 4 boards (smdk310 and Origen) are
broken upstream, likely due to regressions: both defconfigs are
wrong and regulator settings for both boards are broken. That,
allied with some bug at the dummy regulator driver, causes OOPSes
during boot time.
Long story short: even fixing the above, the proposed patches
OOPSed when running the DMABUF test. Not sure yet if the OOPSes
are due to some other undetected regressions, or due to some bug
on the patches.
Due to the above, DMABUF patches for vb2 got NACKed for 3.7."

Merge tag 'pinctrl-for-3.7-late' of git://git./linux/kernel/git/linusw/linux-pinctrl
Pull second set of pinctrl patches from Linus Walleij:
"Here is a late pinctrl pull request with stuff that wasn't quite
tested at the first pull request.
The main reason to not hold off is that the modifications to
irq_domain_add_simple() as reviewed by Rob Herring introduce new
infrastructure for irqdomains that will be useful for the next cycle:
instead of sprinkling irq descriptor allocation all over the kernel
wherever a "legacy" domain is registered, which is necessary for any
platform using sparse IRQs, and many irq chips are say GPIO
controllers which may be used with several systems, some with sparse
IRQs some not, we push this into the irq_domain_add_simple() so we can
atleast do mistakes in one place.
The irq_domain_add_simple() is currently unused in the kernel, so I
need to provide a user. The Nomadik stuff that goes with are changes
to the driver I use day-to-day to make use of this facility (and a
dependency), so see it as a way to eat my own dogfood: if this blows
up the egg hits my face.
A second round of pinctrl patches for v3.7:
- Complement the Nomadik pinctrl driver with alternate Cx functions
so it handles all oddities.
- A patch to the IRQdomain to reform the simple irqdomain to handle
IRQ descriptor allocation dynamically.
- Use the above feature in the Nomadik pin controller."

vfs: bogus warnings in fs/namei.c
The follow_link() function always initializes its *p argument,
or returns an error, but when building with 'gcc -s', the compiler
gets confused by the __always_inline attribute to the function
and can no longer detect where the cookie was initialized.
The solution is to always initialize the pointer from follow_link,
even in the error path. When building with -O2, this has zero impact
on generated code and adds a single instruction in the error path
for a -Os build on ARM.

This is not very likely to happen though, because p9_write_work()
being called with an empty unsent_req_list is not frequent.
But this also means that taking the lock earlier will not be costly.
