Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull namespace updates from Eric Biederman:
"Life has been busy and I have not gotten half as much done this round
as I would have liked. I delayed it so that a minor conflict
resolution with the mips tree could spend a little time in linux-next
before I sent this pull request.
This includes two long delayed user namespace changes from Kirill
Tkhai. It also includes a very useful change from Serge Hallyn that
allows the security capability attribute to be used inside of user
namespaces. The practical effect of this is people can now untar
tarballs and install rpms in user namespaces. It had been suggested to
generalize this and encode some of the namespace information
information in the xattr name. Upon close inspection that makes the
things that should be hard easy and the things that should be easy
more expensive.
Then there is my bugfix/cleanup for signal injection that removes the
magic encoding of the siginfo union member from the kernel internal
si_code. The mips folks reported the case where I had used FPE_FIXME
me is impossible so I have remove FPE_FIXME from mips, while at the
same time including a return statement in that case to keep gcc from
complaining about unitialized variables.
I almost finished the work to get make copy_siginfo_to_user a trivial
copy to user. The code is available at:
git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git neuter-copy_siginfo_to_user-v3
But I did not have time/energy to get the code posted and reviewed
before the merge window opened.
I was able to see that the security excuse for just copying fields
that we know are initialized doesn't work in practice there are buggy
initializations that don't initialize the proper fields in siginfo. So
we still sometimes copy unitialized data to userspace"

* Media error handling support in the Block Translation Table (BTT)
driver is reworked to address sleeping-while-atomic locking and
memory-allocation-context conflicts.
* The dax_device lookup overhead for xfs and ext4 is moved out of the
iomap hot-path to a mount-time lookup.
* A new 'ecc_unit_size' sysfs attribute is added to advertise the
read-modify-write boundary property of a persistent memory range.
* Preparatory fix-ups for arm and powerpc pmem support are included
along with other miscellaneous fixes.

m68k: Add braces to __pmd(x) initializer to kill compiler warning
With gcc 4.1.2:
include/linux/swapops.h: In function ‘swp_entry_to_pmd’:
include/linux/swapops.h:294: warning: missing braces around initializer
include/linux/swapops.h:294: warning: (near initialization for ‘(anonymous).pmd’)
Due to a GCC zero initializer bug (#53119), the standard "(pmd_t){ 0 }"
initializer is not accepted by all GCC versions.
In addition, on m68k pmd_t is an array instead of a single value, so we
need "(pmd_t){ { 0 }, }" instead of "(pmd_t){ 0 }".

sparc64: Handle additional cases of no fault loads
Load instructions using ASI_PNF or other no-fault ASIs should not cause a SIGSEGV or SIGBUS. A garden variety unmapped address follows the TSB miss path, and when no valid mapping is found in the process page tables, the miss handler checks to see if the access was via a no-fault ASI. It then fixes up the target register with a zero, and skips the no-fault load instruction. But different paths are taken for data access exceptions and alignment traps, and these do not respect the no-fault ASI. We add checks in these paths for the no-fault ASI, and fix up the target register and TPC just like in the TSB miss case.

sparc64: speed up etrap/rtrap on NG2 and later processors
For many sun4v processor types, reading or writing a privileged register
has a latency of 40 to 70 cycles. Use a combination of the low-latency
allclean, otherw, normalw, and nop instructions in etrap and rtrap to
replace 2 rdpr and 5 wrpr instructions and improve etrap/rtrap
performance. allclean, otherw, and normalw are available on NG2 and
later processors.
The average ticks to execute the flush windows trap ("ta 0x3") with and
without this patch on select platforms:

IOMMU Updates for Linux v4.14
Slightly more changes than usual this time:
- KDump Kernel IOMMU take-over code for AMD IOMMU. The code now
tries to preserve the mappings of the kernel so that master
aborts for devices are avoided. Master aborts cause some
devices to fail in the kdump kernel, so this code makes the
dump more likely to succeed when AMD IOMMU is enabled.
- Common flush queue implementation for IOVA code users. The
code is still optional, but AMD and Intel IOMMU drivers had
their own implementation which is now unified.
- Finish support for iommu-groups. All drivers implement this
feature now so that IOMMU core code can rely on it.
- Finish support for 'struct iommu_device' in iommu drivers. All
drivers now use the interface.
- New functions in the IOMMU-API for explicit IO/TLB flushing.
This will help to reduce the number of IO/TLB flushes when
IOMMU drivers support this interface.
- Support for mt2712 in the Mediatek IOMMU driver
- New IOMMU driver for QCOM hardware
- System PM support for ARM-SMMU
- Shutdown method for ARM-SMMU-v3
- Some constification patches
- Various other small improvements and fixes

"I ended up splitting the main pull request for this series into two,
mainly because of clashes between NVMe fixes that went into 4.13 after
the for-4.14 branches were split off. This pull request is mostly
NVMe, but not exclusively. In detail, it contains:
- Two pull request for NVMe changes from Christoph. Nothing new on
the feature front, basically just fixes all over the map for the
core bits, transport, rdma, etc.
- Series from Bart, cleaning up various bits in the BFQ scheduler.
- Series of bcache fixes, which has been lingering for a release or
two. Coly sent this in, but patches from various people in this
area.
- Set of patches for BFQ from Paolo himself, updating both
documentation and fixing some corner cases in performance.
- Series from Omar, attempting to now get the 4k loop support
correct. Our confidence level is higher this time.
- Series from Shaohua for loop as well, improving O_DIRECT
performance and fixing a use-after-free"

That can deadlock if this is the last reference since nfs_page_group_destroy() calls nfs_page_group_sync_on_bit().

ARM: 8691/1: Export save_stack_trace_tsk()
The kernel watchdog is a great debugging tool for finding tasks that consume a disproportionate amount of CPU time in contiguous chunks. One can imagine building a similar watchdog for arbitrary driver threads using save_stack_trace_tsk() and print_stack_trace(). However, this is not viable for dynamically loaded driver modules on ARM platforms because save_stack_trace_tsk() is not exported for those architectures. Export save_stack_trace_tsk() for the ARM architecture to align with x86 and support various debugging use cases such as arbitrary driver thread watchdog timers.

Merge branch 'xdp-bpf-fixes'
John Fastabend says: ==================== net: Fixes for XDP/BPF The following fixes, UAPI updates, and small improvement, i. XDP needs to be called inside RCU with preempt disabled. ii. Not strictly a bug fix but we have an attach command in the sockmap UAPI already to avoid having a single kernel released with only the attach and not the detach I'm pushing this into net branch. Its early in the RC cycle so I think this is OK (not ideal but better than supporting a UAPI with a missing detach forever). iii. Final patch replace cpu_relax with cond_resched in devmap. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

bpf: add support for sockmap detach programs
The bpf map sockmap supports adding programs via attach commands. This patch adds the detach command to keep the API symmetric and allow users to remove previously added programs. Otherwise the user would have to delete the map and re-add it to get in this state. This also adds a series of additional tests to capture detach operation and also attaching/detaching invalid prog types. API note: socks will run (or not run) programs depending on the state of the map at the time the sock is added. We do not for example walk the map and remove programs from previously attached socks.

net: rcu lock and preempt disable missing around generic xdp
do_xdp_generic must be called inside rcu critical section with preempt disabled to ensure BPF programs are valid and per-cpu variables used for redirect operations are consistent. This patch ensures this is true and fixes the splat below. The netif_receive_skb_internal() code path is now broken into two rcu critical sections. I decided it was better to limit the preempt_enable/disable block to just the xdp static key portion and the fallout is more rcu_read_lock/unlock calls. Seems like the best option to me.

bpf: don't select potentially stale ri->map from buggy xdp progs
We can potentially run into a couple of issues with the XDP
bpf_redirect_map() helper. The ri->map in the per CPU storage
can become stale in several ways, mostly due to misuse, where
we can then trigger a use after free on the map:
i) prog A is calling bpf_redirect_map(), returning XDP_REDIRECT
and running on a driver not supporting XDP_REDIRECT yet. The
ri->map on that CPU becomes stale when the XDP program is unloaded
on the driver, and a prog B loaded on a different driver which
supports XDP_REDIRECT return code. prog B would have to omit
calling to bpf_redirect_map() and just return XDP_REDIRECT, which
would then access the freed map in xdp_do_redirect() since not
cleared for that CPU.
ii) prog A is calling bpf_redirect_map(), returning a code other
than XDP_REDIRECT. prog A is then detached, which triggers release
of the map. prog B is attached which, similarly as in i), would
just return XDP_REDIRECT without having called bpf_redirect_map()
and thus be accessing the freed map in xdp_do_redirect() since
not cleared for that CPU.
iii) prog A is attached to generic XDP, calling the bpf_redirect_map()
helper and returning XDP_REDIRECT. xdp_do_generic_redirect() is
currently not handling ri->map (will be fixed by Jesper), so it's
not being reset. Later loading a e.g. native prog B which would,
say, call bpf_xdp_redirect() and then returns XDP_REDIRECT would
find in xdp_do_redirect() that a map was set and uses that causing
use after free on map access.
Fix thus needs to avoid accessing stale ri->map pointers, naive
way would be to call a BPF function from drivers that just resets
it to NULL for all XDP return codes but XDP_REDIRECT and including
XDP_REDIRECT for drivers not supporting it yet (and let ri->map
being handled in xdp_do_generic_redirect()). There is a less
intrusive way w/o letting drivers call a reset for each BPF run.
The verifier knows we're calling into bpf_xdp_redirect_map()
helper, so it can do a small insn rewrite transparent to the prog
itself in the sense that it fills R4 with a pointer to the own
bpf_prog. We have that pointer at verification time anyway and
R4 is allowed to be used as per calling convention we scratch
R0 to R5 anyway, so they become inaccessible and program cannot
read them prior to a write. Then, the helper would store the prog
pointer in the current CPUs struct redirect_info. Later in
xdp_do_*_redirect() we check whether the redirect_info's prog
pointer is the same as passed xdp_prog pointer, and if that's
the case then all good, since the prog holds a ref on the map
anyway, so it is always valid at that point in time and must
have a reference count of at least 1. If in the unlikely case
they are not equal, it means we got a stale pointer, so we clear
and bail out right there. Also do reset map and the owning prog
in bpf_xdp_redirect(), so that bpf_xdp_redirect_map() and
bpf_xdp_redirect() won't get mixed up, only the last call should
take precedence. A tc bpf_redirect() doesn't use map anywhere
yet, so no need to clear it there since never accessed in that
layer.
Note that in case the prog is released, and thus the map as
well we're still under RCU read critical section at that time
and have preemption disabled as well. Once we commit with the
__dev_map_insert_ctx() from xdp_do_redirect_map() and set the
map to ri->map_to_flush, we still wait for a xdp_do_flush_map()
to finish in devmap dismantle time once flush_needed bit is set,
so that is fine.
