0991f6a38f bpftool: Only set obj->skeleton on complete success 
After `bpftool gen skeleton`, the ${bpf_app}.skel.h will provide that
${bpf_app_name}__open helper to load bpf. If there is some error
like ENOMEM, the ${bpf_app_name}__open will rollback(free) the allocated
object, including `bpf_object_skeleton`.

Since the ${bpf_app_name}__create_skeleton set the obj->skeleton first
and not rollback it when error, it will cause double-free in
${bpf_app_name}__destory at ${bpf_app_name}__open. Therefore, we should
set the obj->skeleton before return 0;

a32ea51a3f libbpf: Fix possible NULL pointer dereference when destroying skeleton 
When I checked the code in skeleton header file generated with my own
bpf prog, I found there may be possible NULL pointer dereference when
destroying skeleton. Then I checked the in-tree bpf progs, finding that is
a common issue. Let's take the generated samples/bpf/xdp_redirect_cpu.skel.h
for example. Below is the generated code in
xdp_redirect_cpu__create_skeleton():

	xdp_redirect_cpu__create_skeleton
		struct bpf_object_skeleton *s;
		s = (struct bpf_object_skeleton *)calloc(1, sizeof(*s));
		if (!s)
			goto error;
		...
	error:
		bpf_object__destroy_skeleton(s);
		return  -ENOMEM;

After goto error, the NULL 's' will be deferenced in
bpf_object__destroy_skeleton().

We can simply fix this issue by just adding a NULL check in
bpf_object__destroy_skeleton().

622a5b582c bpftool: Fix error check when calling hashmap__new() 
hashmap__new() encodes errors with ERR_PTR(), hence it's not valid to
check the returned pointer against NULL and IS_ERR() has to be used
instead.

libbpf_get_error() can't be used in this case as hashmap__new() is not
part of the public libbpf API and it'll continue using ERR_PTR() after
libbpf 1.0.

fba60b171a libbpf: Use IS_ERR_OR_NULL() in hashmap__free() 
hashmap__new() uses ERR_PTR() to return an error so it's better to
use IS_ERR_OR_NULL() in order to check the pointer before calling
free(). This will prevent freeing an invalid pointer if somebody calls
hashmap__free() with the result of a failed hashmap__new() call.

63045bfd3c netfilter: nf_tables: don't use 'data_size' uninitialized 
Commit 2c865a8a28 ("netfilter: nf_tables: add rule blob layout") never
initialized the new 'data_size' variable.

I'm not sure how it ever worked, but it might have worked almost by
accident - gcc seems to occasionally miss these kinds of 'variable used
uninitialized' situations, but I've seen it do so because it ended up
zero-initializing them due to some other simplification.

But clang is very unhappy about it all, and correctly reports

    net/netfilter/nf_tables_api.c:8278:4: error: variable 'data_size' is uninitialized when used here [-Werror,-Wuninitialized]
                            data_size += sizeof(*prule) + rule->dlen;
                            ^~~~~~~~~
    net/netfilter/nf_tables_api.c:8263:30: note: initialize the variable 'data_size' to silence this warning
            unsigned int size, data_size;
                                        ^
                                         = 0
    1 error generated.

and this fix just initializes 'data_size' to zero before the loop.

    to decrease cross-CPU allocator work and improve latency.
 
  - Add netdevice refcount tracking to locate sources of netdevice
    and net namespace refcount leaks.
 
  - Make Tx watchdog less intrusive - avoid pausing Tx and restarting
    all queues from a single CPU removing latency spikes.
 
  - Various small optimizations throughout the stack from Eric Dumazet.
 
  - Make netdev->dev_addr[] constant, force modifications to go via
    appropriate helpers to allow us to keep addresses in ordered data
    structures.
 
  - Replace unix_table_lock with per-hash locks, improving performance
    of bind() calls.
 
  - Extend skb drop tracepoint with a drop reason.
 
  - Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.
 
 BPF
 ---
 
  - New helpers:

  - Support BPF relocations (CO-RE) in the kernel loader.
 
  - Further the support for BTF_TYPE_TAG annotations.
 
  - Allow access to local storage in sleepable helpers.
 
  - Convert verifier argument types to a composable form with different
    attributes which can be shared across types (ro, maybe-null).

    - support fastclose option (quick shutdown of the full MPTCP
      connection, similar to TCP RST in regular TCP)
 
  - MCTP (Management Component Transport) over serial, as defined by
    DMTF spec DSP0253 - "MCTP Serial Transport Binding".
 
 Driver API
 ----------
 
  - Support timestamping on bond interfaces in active/passive mode.
 
  - Introduce generic phylink link mode validation for drivers which
    don't have any quirks and where MAC capability bits fully express
    what's supported. Allow PCS layer to participate in the validation.
    Convert a number of drivers.
 
  - Add support to set/get size of buffers on the Rx rings and size of
    the tx copybreak buffer via ethtool.
 
  - Support offloading TC actions as first-class citizens rather than
    only as attributes of filters, improve sharing and device resource
    utilization.

      - improvements in the data scheduler (assigning data to subflows)
      - support fastclose option (quick shutdown of the full MPTCP
        connection, similar to TCP RST in regular TCP)

   - MCTP (Management Component Transport) over serial, as defined by
     DMTF spec DSP0253 - "MCTP Serial Transport Binding".

  Driver API
  ----------

   - Support timestamping on bond interfaces in active/passive mode.

   - Introduce generic phylink link mode validation for drivers which
     don't have any quirks and where MAC capability bits fully express
     what's supported. Allow PCS layer to participate in the validation.
     Convert a number of drivers.

   - Add support to set/get size of buffers on the Rx rings and size of
     the tx copybreak buffer via ethtool.

   - Support offloading TC actions as first-class citizens rather than
     only as attributes of filters, improve sharing and device resource
     utilization.

   - WiFi (mac80211/cfg80211):
      - support forwarding offload (ndo_fill_forward_path)
      - support for background radar detection hardware
      - SA Query Procedures offload on the AP side

Pull slab updates from Vlastimil Babka:

 - Separate struct slab from struct page - an offshot of the page folio
   work.

   Struct page fields used by slab allocators are moved from struct page
   to a new struct slab, that uses the same physical storage. Similar to
   struct folio, it always is a head page. This brings better type
   safety, separation of large kmalloc allocations from true slabs, and
   cleanup of related objcg code.

 - A SLAB_MERGE_DEFAULT config optimization.

d93aebbd76 Merge branch 'random-5.17-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random 
Pull random number generator updates from Jason Donenfeld:
 "These a bit more numerous than usual for the RNG, due to folks
  resubmitting patches that had been pending prior and generally renewed
  interest.

  There are a few categories of patches in here:

   1) Dominik Brodowski and I traded a series back and forth for a some
      weeks that fixed numerous issues related to seeds being provided
      at extremely early boot by the firmware, before other parts of the
      kernel or of the RNG have been initialized, both fixing some
      crashes and addressing correctness around early boot randomness.
      One of these is marked for stable.

   2) I replaced the RNG's usage of SHA-1 with BLAKE2s in the entropy
      extractor, and made the construction a bit safer and more
      standard. This was sort of a long overdue low hanging fruit, as we
      were supposed to have phased out SHA-1 usage quite some time ago
      (even if all we needed here was non-invertibility). Along the way
      it also made extraction 131% faster. This required a bit of
      Kconfig and symbol plumbing to make things work well with the
      crypto libraries, which is one of the reasons why I'm sending you
      this pull early in the cycle.

   3) I got rid of a truly superfluous call to RDRAND in the hot path,
      which resulted in a whopping 370% increase in performance.

   4) Sebastian Andrzej Siewior sent some patches regarding PREEMPT_RT,
      the full series of which wasn't ready yet, but the first two
      preparatory cleanups were good on their own. One of them touches
      files in kernel/irq/, which is the other reason why I'm sending
      you this pull early in the cycle.

   5) Other assorted correctness fixes from Eric Biggers, Jann Horn,
      Mark Brown, Dominik Brodowski, and myself"

   - First part of a series to move the AMD address translation code
     from arch/x86/ to amd64_edac as that is its only user anyway

   - Some MCE error injection improvements to the AMD side

   - Reorganization of the #MC handler code and the facilities it calls
     to make it noinstr-safe

   - Add support for new AMD MCA bank types and non-uniform banks layout

   - The usual set of cleanups and fixes"

Pull x86 SGX updates from Borislav Petkov:

 - Add support for handling hw errors in SGX pages: poisoning,
   recovering from poison memory and error injection into SGX pages

 - A bunch of changes to the SGX selftests to simplify and allow of SGX
   features testing without the need of a whole SGX software stack

 - Add a sysfs attribute which is supposed to show the amount of SGX
   memory in a NUMA node, similar to what /proc/meminfo is to normal
   memory

 - The usual bunch of fixes and cleanups too

9b9e211360 arm64 updates for 5.17: 
- KCSAN enabled for arm64.
 
 - Additional kselftests to exercise the syscall ABI w.r.t. SVE/FPSIMD.
 
 - Some more SVE clean-ups and refactoring in preparation for SME support
   (scalable matrix extensions).
 
 - BTI clean-ups (SYM_FUNC macros etc.)
 
 - arm64 atomics clean-up and codegen improvements.
 
 - HWCAPs for FEAT_AFP (alternate floating point behaviour) and
   FEAT_RPRESS (increased precision of reciprocal estimate and reciprocal
   square root estimate).
 
 - Use SHA3 instructions to speed-up XOR.
 
 - arm64 unwind code refactoring/unification.
 
 - Avoid DC (data cache maintenance) instructions when DCZID_EL0.DZP == 1
   (potentially set by a hypervisor; user-space already does this).
 
 - Perf updates for arm64: support for CI-700, HiSilicon PCIe PMU,
   Marvell CN10K LLC-TAD PMU, miscellaneous clean-ups.
 
 - Other fixes and clean-ups; highlights: fix the handling of erratum
   1418040, correct the calculation of the nomap region boundaries,
   introduce io_stop_wc() mapped to the new DGH instruction (data
   gathering hint).

bb4ed26e7e SoC: Add support for StarFive JH7100 RISC-V SoC 
This adds support for the StarFive JH7100, including the necessary
 device drivers and DT files for the BeagleV Starlight prototype
 board, with additional boards to be added later. This SoC promises
 to be the first usable low-cost platform for RISC-V.
 
 I've taken this through the SoC tree in the anticipation of adding
 a few other Arm based SoCs as well, but those did not pass the
 review in time, so it's only this one.

aca48b2dd1 ARM: SoC devicetree changes for v5.17 
As usual, this is the bulk of the updates for the SoC tree, adding
 more devices to existing files, addressing issues from ever improving
 automated checking, and fixing minor issues.
 
 The most interesting bits as usual are the new platforms.
 All the newly supported SoCs belong into existing families
 this time:
 
  - Qualcomm gets support for two newly announced platforms, both
    of which can now work in production environments: the SDX65
    5G modem that can run a minimal Linux on its Cortex-A7 core,
    and the Snapdragon 8 Gen 1, their latest high-end phone SoC.
 
  - Renesas adds support for R-Car S4-8, the most recent automotive
    Server/Communication SoC.
 
  - TI adds support for J721s2, a new automotive SoC in the K3
    family.
 
  - Mediatek MT7986a/b is a SoC used in Wifi routers, the latest
    generation following their popular MT76xx series. Only basic
    support is added for now.
 
  - NXP i.MX8 ULP8 is a new low-power variant of the widespread
    i.MX8 series.
 
  - TI SPEAr320s is a minor variant of the old SPEAr320 SoC that
    we have supported for a long time.
 
 New boards with the existing SoCs include
 
  - Aspeed AST2500/AST2600 BMCs in TYAN, Facebook and Yadro servers
 
  - AT91/SAMA5 based evaluation board
 
  - NXP gains twenty new development and industrial boards for their
    i.MX and Layerscape SoCs
 
  - Intel IXP4xx now supports the final two machines in device tree
    that were previously only supported in old style board files.
 
  - Mediatek MT6589 is used in the Fairphone FP1 phone from 2013,
    while MT8183 is used in the Acer Chromebook 314.
 
  - Qualcomm gains support for the reference machines using the two
    new SoCs, plus a number of Chromebook variants and phones based
    on the Snapdragon 7c, 845 and 888 SoCs, including various
    Sony Xperia devices and the Microsoft Surface Duo 2.
 
  - ST STM32 now supports the Engicam i.Core STM32MP1 carrier board.
 
  - Tegra now boots various older Android devices based on 32-bit
    chips out of the box, including a number of ASUS Transformer
    tablets.
    There is also a new Jetson AGX Orin developer kit.
 
  - Apple support adds the missing device trees for all the remaining
    M1 Macbook and iMac variants, though not yet the M1 Pro/Max
    versions.
 
  - Allwinner now supports another version of the Tanix TX6 set-top
    box based on the H6 SoC.
 
  - Broadcom gains support for the Netgear RAXE500 Wireless router
    based on BCM4908.
