kernel: bump 5.10 to 5.10.20

Also add a new kconfig symbol (CONFIG_KCMP) to the generic config,
disabling the SYS_kcmp syscall (it was split from
CONFIG_CHECKPOINT_RESTORE, which is disabled by default, so the
previous behaviour is kept).

-Subject: [PATCH] net: icmp: pass zeroed opts from icmp{,v6}_ndo_send before
- sending
-
-commit ee576c47db60432c37e54b1e2b43a8ca6d3a8dca upstream.
-
-The icmp{,v6}_send functions make all sorts of use of skb->cb, casting
-it with IPCB or IP6CB, assuming the skb to have come directly from the
-inet layer. But when the packet comes from the ndo layer, especially
-when forwarded, there's no telling what might be in skb->cb at that
-point. As a result, the icmp sending code risks reading bogus memory
-contents, which can result in nasty stack overflows such as this one
-reported by a user:
-
-    panic+0x108/0x2ea
-    __stack_chk_fail+0x14/0x20
-    __icmp_send+0x5bd/0x5c0
-    icmp_ndo_send+0x148/0x160
-
-In icmp_send, skb->cb is cast with IPCB and an ip_options struct is read
-from it. The optlen parameter there is of particular note, as it can
-induce writes beyond bounds. There are quite a few ways that can happen
-in __ip_options_echo. For example:
-
-    // sptr/skb are attacker-controlled skb bytes
-    sptr = skb_network_header(skb);
-    // dptr/dopt points to stack memory allocated by __icmp_send
-    dptr = dopt->__data;
-    // sopt is the corrupt skb->cb in question
-    if (sopt->rr) {
-        optlen  = sptr[sopt->rr+1]; // corrupt skb->cb + skb->data
-        soffset = sptr[sopt->rr+2]; // corrupt skb->cb + skb->data
-	// this now writes potentially attacker-controlled data, over
-	// flowing the stack:
-        memcpy(dptr, sptr+sopt->rr, optlen);
-    }
-
-In the icmpv6_send case, the story is similar, but not as dire, as only
-IP6CB(skb)->iif and IP6CB(skb)->dsthao are used. The dsthao case is
-worse than the iif case, but it is passed to ipv6_find_tlv, which does
-a bit of bounds checking on the value.
-
-This is easy to simulate by doing a `memset(skb->cb, 0x41,
-sizeof(skb->cb));` before calling icmp{,v6}_ndo_send, and it's only by
-good fortune and the rarity of icmp sending from that context that we've
-avoided reports like this until now. For example, in KASAN:
-
-    BUG: KASAN: stack-out-of-bounds in __ip_options_echo+0xa0e/0x12b0
-    Write of size 38 at addr ffff888006f1f80e by task ping/89
-    CPU: 2 PID: 89 Comm: ping Not tainted 5.10.0-rc7-debug+ #5
-    Call Trace:
-     dump_stack+0x9a/0xcc
-     print_address_description.constprop.0+0x1a/0x160
-     __kasan_report.cold+0x20/0x38
-     kasan_report+0x32/0x40
-     check_memory_region+0x145/0x1a0
-     memcpy+0x39/0x60
-     __ip_options_echo+0xa0e/0x12b0
-     __icmp_send+0x744/0x1700
-
-Actually, out of the 4 drivers that do this, only gtp zeroed the cb for
-the v4 case, while the rest did not. So this commit actually removes the
-gtp-specific zeroing, while putting the code where it belongs in the
-shared infrastructure of icmp{,v6}_ndo_send.
-
-This commit fixes the issue by passing an empty IPCB or IP6CB along to
-the functions that actually do the work. For the icmp_send, this was
-already trivial, thanks to __icmp_send providing the plumbing function.
-For icmpv6_send, this required a tiny bit of refactoring to make it
-behave like the v4 case, after which it was straight forward.
-
-Fixes: a2b78e9b2cac ("sunvnet: generate ICMP PTMUD messages for smaller port MTUs")

-
-commit 8b5553ace83cced775eefd0f3f18b5c6214ccf7a upstream.
-
-Having two ring buffers per-peer means that every peer results in two
-massive ring allocations. On an 8-core x86_64 machine, this commit
-reduces the per-peer allocation from 18,688 bytes to 1,856 bytes, which
-is an 90% reduction. Ninety percent! With some single-machine
-deployments approaching 500,000 peers, we're talking about a reduction
-from 7 gigs of memory down to 700 megs of memory.
-
-In order to get rid of these per-peer allocations, this commit switches
-to using a list-based queueing approach. Currently GSO fragments are
-chained together using the skb->next pointer (the skb_list_* singly
-linked list approach), so we form the per-peer queue around the unused
-skb->prev pointer (which sort of makes sense because the links are
-pointing backwards). Use of skb_queue_* is not possible here, because
-that is based on doubly linked lists and spinlocks. Multiple cores can
-write into the queue at any given time, because its writes occur in the
-start_xmit path or in the udp_recv path. But reads happen in a single
-workqueue item per-peer, amounting to a multi-producer, single-consumer
-paradigm.
-
-The MPSC queue is implemented locklessly and never blocks. However, it
-is not linearizable (though it is serializable), with a very tight and
-unlikely race on writes, which, when hit (some tiny fraction of the
-0.15% of partial adds on a fully loaded 16-core x86_64 system), causes
-the queue reader to terminate early. However, because every packet sent
-queues up the same workqueue item after it is fully added, the worker
-resumes again, and stopping early isn't actually a problem, since at
-that point the packet wouldn't have yet been added to the encryption
-queue. These properties allow us to avoid disabling interrupts or
-spinning. The design is based on Dmitry Vyukov's algorithm [1].
-
-Performance-wise, ordinarily list-based queues aren't preferable to
-ringbuffers, because of cache misses when following pointers around.
-However, we *already* have to follow the adjacent pointers when working
-through fragments, so there shouldn't actually be any change there. A
-potential downside is that dequeueing is a bit more complicated, but the
-ptr_ring structure used prior had a spinlock when dequeueing, so all and
-all the difference appears to be a wash.
-
-Actually, from profiling, the biggest performance hit, by far, of this
-commit winds up being atomic_add_unless(count, 1, max) and atomic_
-dec(count), which account for the majority of CPU time, according to
-perf. In that sense, the previous ring buffer was superior in that it
-could check if it was full by head==tail, which the list-based approach
-cannot do.
-
-But all and all, this enables us to get massive memory savings, allowing
-WireGuard to scale for real world deployments, without taking much of a
-performance hit.

-Subject: [PATCH] wireguard: kconfig: use arm chacha even with no neon
-
-commit bce2473927af8de12ad131a743f55d69d358c0b9 upstream.
-
-The condition here was incorrect: a non-neon fallback implementation is
-available on arm32 when NEON is not supported.

-Subject: USB: serial: option: update interface mapping for ZTE P685M
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-This patch prepares for qmi_wwan driver support for the device.
-Previously "option" driver mapped itself to interfaces 0 and 3 (matching
-ff/ff/ff), while interface 3 is in fact a QMI port.
-Interfaces 1 and 2 (matching ff/00/00) expose AT commands,
-and weren't supported previously at all.
-Without this patch, a possible conflict would exist if device ID was
-added to qmi_wwan driver for interface 3.
-
-Update and simplify device ID to match interfaces 0-2 directly,
-to expose QCDM (0), PCUI (1), and modem (2) ports and avoid conflict
-with QMI (3), and ADB (4).
-
-The modem is used inside ZTE MF283+ router and carriers identify it as
-such.
-Interface mapping is:
-0: QCDM, 1: AT (PCUI), 2: AT (Modem), 3: QMI, 4: ADB
