Subject: [1/2] drivers/net: Disable UFO through virtio
Origin: https://git.kernel.org/cgit/linux/kernel/git/davem/net.git/commit?id=3d0ad09412ffe00c9afa201d01effdb6023d09b4
IPv6 does not allow fragmentation by routers, so there is no
fragmentation ID in the fixed header. UFO for IPv6 requires the ID to
be passed separately, but there is no provision for this in the virtio
net protocol.
Until recently our software implementation of UFO/IPv6 generated a new
ID, but this was a bug. Now we will use ID=0 for any UFO/IPv6 packet
passed through a tap, which is even worse.
Unfortunately there is no distinction between UFO/IPv4 and v6
features, so disable UFO on taps and virtio_net completely until we
have a proper solution.
We cannot depend on VM managers respecting the tap feature flags, so
keep accepting UFO packets but log a warning the first time we do
this.

Subject: [2/2] drivers/net, ipv6: Select IPv6 fragment idents for virtio UFO
packets
Origin: https://git.kernel.org/cgit/linux/kernel/git/davem/net.git/commit?id=5188cd44c55db3e92cd9e77a40b5baa7ed4340f7
UFO is now disabled on all drivers that work with virtio net headers,
but userland may try to send UFO/IPv6 packets anyway. Instead of
sending with ID=0, we should select identifiers on their behalf (as we
used to).

Subject: [PATCH] of/fdt: memblock_reserve /memreserve/ regions in the case of
partial overlap
Origin: https://git.kernel.org/cgit/linux/kernel/git/glikely/linux.git/commit/?h=devicetree/merge&id=094cb98179f19b75acf9ff471daabf3948ce98e6
memblock_is_region_reserved() returns true in the case of a partial
overlap, meaning that the current code fails to reserve the
non-overlapping portion.
This call was introduced as part of d1552ce449eb "of/fdt: move
memreserve and dtb memory reservations into core" which went into
v3.16.
I observed this causing a Midway system with a buggy fdt (the header
declares itself to be larger than it really is) failing to boot
because the over-inflated size of the fdt was causing it to seem to
run into the swapper_pg_dir region, meaning the DT wasn't reserved.
The symptoms were failing to find an disks or network and failing to
boot.
However given the ambiguity of whether things like the initrd are
covered by /memreserve/ and similar I think it is best to also
register the region rather than just ignoring it.
Since memblock_reserve() handles overlaps just fine lets just warn and
carry on.

Subject: Revert "drivers/net: Disable UFO through virtio" in macvtap and tun
From: Ben Hutchings <ben@decadent.org.uk>
Date: Tue, 11 Nov 2014 17:12:58 +0000
This reverts commit 88e0e0e5aa722b193c8758c8b45d041de5316924 for
the tap drivers, but leaves UFO disabled in virtio_net.
libvirt at least assumes that tap features will never be dropped
in new kernel versions, and doing so prevents migration of VMs to
the never kernel version while they are running with virtio net
devices.

Subject: vfs: Don't exchange "short" filenames unconditionally.
Origin: https://git.kernel.org/linus/d2fa4a8476b911782f7e5167db18770222ac40c3
Only exchange source and destination filenames
if flags contain RENAME_EXCHANGE.
In case if executable file was running and replaced by
other file /proc/PID/exe should still show correct file name,
not the old name of the file by which it was replaced.
The scenario when this bug manifests itself was like this:
* ALT Linux uses rpm and start-stop-daemon;
* during a package upgrade rpm creates a temporary file
for an executable to rename it upon successful unpacking;
* start-stop-daemon is run subsequently and it obtains
the (nonexistant) temporary filename via /proc/PID/exe
thus failing to identify the running process.
Note that "long" filenames (> DNAiME_INLINE_LEN) are still
exchanged without RENAME_EXCHANGE and this behaviour exists
long enough (should be fixed too apparently).
So this patch is just an interim workaround that restores
behavior for "short" names as it was before changes
introduced by commit da1ce0670c14 ("vfs: add cross-rename").
See https://lkml.org/lkml/2014/9/7/6 for details.
AV: the comments about being more careful with ->d_name.hash
than with ->d_name.name are from back in 2.3.40s; they
became obsolete by 2.3.60s, when we started to unhash the
target instead of swapping hash chain positions followed
by d_delete() as we used to do when dcache was first
introduced.

Origin: https://git.kernel.org/linus/7c2105fbe9658d6cee18751568e29579bb58bfec
This fixes the following build failure when building with CONFIG_MODVERSIONS
enabled:

The $(obj)/aes-glue-%.o rule only creates $(obj)/.tmp_aes-glue-ce.o, it
should use if_changed_rule instead of if_changed_dep.

These functions can be executed on the int3 stack, so kprobes
are dangerous. Tracing is probably a bad idea, too.

Origin: https://git.kernel.org/linus/af726f21ed8af2cdaa4e93098dc211521218ae65
There's nothing special enough about the espfix64 double fault fixup to
justify writing it in assembly. Move it to C.
This also fixes a bug: if the double fault came from an IST stack, the
old asm code would return to a partially uninitialized stack frame.

Origin: https://git.kernel.org/linus/b645af2d5905c4e32399005b867987919cbfc3ae
It's possible for iretq to userspace to fail. This can happen because
of a bad CS, SS, or RIP.
Historically, we've handled it by fixing up an exception from iretq to
land at bad_iret, which pretends that the failed iret frame was really
the hardware part of #GP(0) from userspace. To make this work, there's
an extra fixup to fudge the gs base into a usable state.
This is suboptimal because it loses the original exception. It's also
buggy because there's no guarantee that we were on the kernel stack to
begin with. For example, if the failing iret happened on return from an
NMI, then we'll end up executing general_protection on the NMI stack.
This is bad for several reasons, the most immediate of which is that
general_protection, as a non-paranoid idtentry, will try to deliver
signals and/or schedule from the wrong stack.
This patch throws out bad_iret entirely. As a replacement, it augments
the existing swapgs fudge into a full-blown iret fixup, mostly written
in C. It's should be clearer and more correct.

Subject: x86_64, traps: Stop using IST for #SS
Origin: https://git.kernel.org/linus/6f442be2fb22be02cafa606f1769fa1e6f894441
On a 32-bit kernel, this has no effect, since there are no IST stacks.
On a 64-bit kernel, #SS can only happen in user code, on a failed iret
to user space, a canonical violation on access via RSP or RBP, or a
genuine stack segment violation in 32-bit kernel code. The first two
cases don't need IST, and the latter two cases are unlikely fatal bugs,
and promoting them to double faults would be fine.
This fixes a bug in which the espfix64 code mishandles a stack segment
violation.
This saves 4k of memory per CPU and a tiny bit of code.
