Networking changes for 5.14.
Core:
- BPF:
- add syscall program type and libbpf support for generating
instructions and bindings for in-kernel BPF loaders (BPF loaders
for BPF), this is a stepping stone for signed BPF programs
- infrastructure to migrate TCP child sockets from one listener
to another in the same reuseport group/map to improve flexibility
of service hand-off/restart
- add broadcast support to XDP redirect
- allow bypass of the lockless qdisc to improving performance
(for pktgen: +23% with one thread, +44% with 2 threads)
- add a simpler version of "DO_ONCE()" which does not require
jump labels, intended for slow-path usage
- virtio/vsock: introduce SOCK_SEQPACKET support
- add getsocketopt to retrieve netns cookie
- ip: treat lowest address of a IPv4 subnet as ordinary unicast address
allowing reclaiming of precious IPv4 addresses
- ipv6: use prandom_u32() for ID generation
- ip: add support for more flexible field selection for hashing
across multi-path routes (w/ offload to mlxsw)
- icmp: add support for extended RFC 8335 PROBE (ping)
- seg6: add support for SRv6 End.DT46 behavior
- mptcp:
- DSS checksum support (RFC 8684) to detect middlebox meddling
- support Connection-time 'C' flag
- time stamping support
- sctp: packetization Layer Path MTU Discovery (RFC 8899)
- xfrm: speed up state addition with seq set
- WiFi:
- hidden AP discovery on 6 GHz and other HE 6 GHz improvements
- aggregation handling improvements for some drivers
- minstrel improvements for no-ack frames
- deferred rate control for TXQs to improve reaction times
- switch from round robin to virtual time-based airtime scheduler
- add trace points:
- tcp checksum errors
- openvswitch - action execution, upcalls
- socket errors via sk_error_report
Device APIs:
- devlink: add rate API for hierarchical control of max egress rate
of virtual devices (VFs, SFs etc.)
- don't require RCU read lock to be held around BPF hooks
in NAPI context
- page_pool: generic buffer recycling
New hardware/drivers:
- mobile:
- iosm: PCIe Driver for Intel M.2 Modem
- support for Qualcomm MSM8998 (ipa)
- WiFi: Qualcomm QCN9074 and WCN6855 PCI devices

atm: nicstar: use 'dma_free_coherent' instead of 'kfree'
When 'nicstar_init_one' fails, 'ns_init_card_error' will be executed for error handling, but the correct memory free function should be used, otherwise it will cause an error.

Networking changes for 5.13.
Core:
- bpf:
- allow bpf programs calling kernel functions (initially to
reuse TCP congestion control implementations)
- enable task local storage for tracing programs - remove the
need to store per-task state in hash maps, and allow tracing
programs access to task local storage previously added for
BPF_LSM
- add bpf_for_each_map_elem() helper, allowing programs to
walk all map elements in a more robust and easier to verify
fashion
- sockmap: support UDP and cross-protocol BPF_SK_SKB_VERDICT
redirection
- lpm: add support for batched ops in LPM trie
- add BTF_KIND_FLOAT support - mostly to allow use of BTF
on s390 which has floats in its headers files
- improve BPF syscall documentation and extend the use of kdoc
parsing scripts we already employ for bpf-helpers
- libbpf, bpftool: support static linking of BPF ELF files
- improve support for encapsulation of L2 packets
- xdp: restructure redirect actions to avoid a runtime lookup,
improving performance by 4-8% in microbenchmarks
- xsk: build skb by page (aka generic zerocopy xmit) - improve
performance of software AF_XDP path by 33% for devices
which don't need headers in the linear skb part (e.g. virtio)
- nexthop: resilient next-hop groups - improve path stability
on next-hops group changes (incl. offload for mlxsw)
- ipv6: segment routing: add support for IPv4 decapsulation
- icmp: add support for RFC 8335 extended PROBE messages
- inet: use bigger hash table for IP ID generation
- tcp: deal better with delayed TX completions - make sure we don't
give up on fast TCP retransmissions only because driver is
slow in reporting that it completed transmitting the original
- tcp: reorder tcp_congestion_ops for better cache locality
- mptcp:
- add sockopt support for common TCP options
- add support for common TCP msg flags
- include multiple address ids in RM_ADDR
- add reset option support for resetting one subflow
- udp: GRO L4 improvements - improve 'forward' / 'frag_list'
co-existence with UDP tunnel GRO, allowing the first to take
place correctly even for encapsulated UDP traffic
- micro-optimize dev_gro_receive() and flow dissection, avoid
retpoline overhead on VLAN and TEB GRO
- use less memory for sysctls, add a new sysctl type, to allow using
u8 instead of "int" and "long" and shrink networking sysctls
- veth: allow GRO without XDP - this allows aggregating UDP
packets before handing them off to routing, bridge, OvS, etc.
- allow specifing ifindex when device is moved to another namespace
- netfilter:
- nft_socket: add support for cgroupsv2
- nftables: add catch-all set element - special element used
to define a default action in case normal lookup missed
- use net_generic infra in many modules to avoid allocating
per-ns memory unnecessarily
- xps: improve the xps handling to avoid potential out-of-bound
accesses and use-after-free when XPS change race with other
re-configuration under traffic
- add a config knob to turn off per-cpu netdev refcnt to catch
underflows in testing
Device APIs:
- add WWAN subsystem to organize the WWAN interfaces better and
hopefully start driving towards more unified and vendor-
-independent APIs
- ethtool:
- add interface for reading IEEE MIB stats (incl. mlx5 and
bnxt support)
- allow network drivers to dump arbitrary SFP EEPROM data,
current offset+length API was a poor fit for modern SFP
which define EEPROM in terms of pages (incl. mlx5 support)
- act_police, flow_offload: add support for packet-per-second
policing (incl. offload for nfp)
- psample: add additional metadata attributes like transit delay
for packets sampled from switch HW (and corresponding egress
and policy-based sampling in the mlxsw driver)
- dsa: improve support for sandwiched LAGs with bridge and DSA
- netfilter:
- flowtable: use direct xmit in topologies with IP
forwarding, bridging, vlans etc.
- nftables: counter hardware offload support
- Bluetooth:
- improvements for firmware download w/ Intel devices
- add support for reading AOSP vendor capabilities
- add support for virtio transport driver
- mac80211:
- allow concurrent monitor iface and ethernet rx decap
- set priority and queue mapping for injected frames
- phy: add support for Clause-45 PHY Loopback
- pci/iov: add sysfs MSI-X vector assignment interface
to distribute MSI-X resources to VFs (incl. mlx5 support)
New hardware/drivers:
- dsa: mv88e6xxx: add support for Marvell mv88e6393x -
11-port Ethernet switch with 8x 1-Gigabit Ethernet
and 3x 10-Gigabit interfaces.
- dsa: support for legacy Broadcom tags used on BCM5325, BCM5365
and BCM63xx switches
- Microchip KSZ8863 and KSZ8873; 3x 10/100Mbps Ethernet switches
- ath11k: support for QCN9074 a 802.11ax device
- Bluetooth: Broadcom BCM4330 and BMC4334
- phy: Marvell 88X2222 transceiver support
- mdio: add BCM6368 MDIO mux bus controller
- r8152: support RTL8153 and RTL8156 (USB Ethernet) chips
- mana: driver for Microsoft Azure Network Adapter (MANA)
- Actions Semi Owl Ethernet MAC
- can: driver for ETAS ES58X CAN/USB interfaces
Pure driver changes:
- add XDP support to: enetc, igc, stmmac
- add AF_XDP support to: stmmac
- virtio:
- page_to_skb() use build_skb when there's sufficient tailroom
(21% improvement for 1000B UDP frames)
- support XDP even without dedicated Tx queues - share the Tx
queues with the stack when necessary
- mlx5:
- flow rules: add support for mirroring with conntrack,
matching on ICMP, GTP, flex filters and more
- support packet sampling with flow offloads
- persist uplink representor netdev across eswitch mode
changes
- allow coexistence of CQE compression and HW time-stamping
- add ethtool extended link error state reporting

The usual updates from the irq departement:
Core changes:
- Provide IRQF_NO_AUTOEN as a flag for request*_irq() so drivers can be
cleaned up which either use a seperate mechanism to prevent auto-enable
at request time or have a racy mechanism which disables the interrupt
right after request.
- Get rid of the last usage of irq_create_identity_mapping() and remove
the interface.
- An overhaul of tasklet_disable(). Most usage sites of tasklet_disable()
are in task context and usually in cleanup, teardown code pathes.
tasklet_disable() spinwaits for a tasklet which is currently executed.
That's not only a problem for PREEMPT_RT where this can lead to a live
lock when the disabling task preempts the softirq thread. It's also
problematic in context of virtualization when the vCPU which runs the
tasklet is scheduled out and the disabling code has to spin wait until
it's scheduled back in. Though there are a few code pathes which invoke
tasklet_disable() from non-sleepable context. For these a new disable
variant which still spinwaits is provided which allows to switch
tasklet_disable() to a sleep wait mechanism. For the atomic use cases
this does not solve the live lock issue on PREEMPT_RT. That is mitigated
by blocking on the RT specific softirq lock.
- The PREEMPT_RT specific implementation of softirq processing and
local_bh_disable/enable().
On RT enabled kernels soft interrupt processing happens always in task
context and all interrupt handlers, which are not explicitly marked to
be invoked in hard interrupt context are forced into task context as
well. This allows to protect against softirq processing with a per
CPU lock, which in turn allows to make BH disabled regions preemptible.
Most of the softirq handling code is still shared. The RT/non-RT
specific differences are addressed with a set of inline functions which
provide the context specific functionality. The local_bh_disable() /
local_bh_enable() mechanism are obviously seperate.
- The usual set of small improvements and cleanups
Driver changes:
- New drivers for Nuvoton WPCM450 and DT 79rc3243x interrupt controllers
- Extended functionality for MStar, STM32 and SC7280 irq chips
- Enhanced robustness for ARM GICv3/4.1 drivers
- The usual set of cleanups and improvements all over the place

atm: eni: Use tasklet_disable_in_atomic() in the send() callback
The atmdev_ops::send callback which calls tasklet_disable() is invoked with bottom halfs disabled from net_device_ops::ndo_start_xmit(). All other invocations of tasklet_disable() in this driver happen in preemptible context. Change the send() call to use tasklet_disable_in_atomic() which allows tasklet_disable() to be made sleepable once the remaining atomic context usage sites are cleaned up.

atm: idt77252: fix null-ptr-dereference
this one is similar to the phy_data allocation fix in uPD98402, the driver allocate the idt77105_priv and store to dev_data but later dereference using dev->dev_data, which will cause null-ptr-dereference. fix this issue by changing dev_data to phy_data so that PRIV(dev) can work correctly.

atm: uPD98402: fix incorrect allocation
dev->dev_data is set in zatm.c, calling zatm_start() will overwrite this dev->dev_data in uPD98402_start() and a subsequent PRIV(dev)->lock (i.e dev->phy_data->lock) will result in a null-ptr-dereference.

atm: lanai: dont run lanai_dev_close if not open
lanai_dev_open() can fail. When it fail, lanai->base is unmapped and the pci device is disabled. The caller, lanai_init_one(), then tries to run atm_dev_deregister(). This will subsequently call lanai_dev_close() and use the already released MMIO area. To fix this issue, set the lanai->base to NULL if open fail, and test the flag in lanai_dev_close().

atm: lanai: Remove in_interrupt() usage
lanai_shutdown_tx_vci() uses in_interrupt() to issue a warning message if the function was used in context in which it is not safe to sleep. The usage of in_interrupt() in driver code is deprecated as it can not always detect all states where it is not allowed to sleep. msleep() has debug code which will trigger a warning if used in bad context.

atm: nicstar: Replace in_interrupt() usage
push_scqe() uses in_interrupt() to figure out if it is allowed to sleep. The usage of in_interrupt() in drivers is phased out and Linus clearly requested that code which changes behaviour depending on context should either be separated or the context be conveyed in an argument passed by the caller, which usually knows the context. Aside of that in_interrupt() is not correct as it does not catch preempt disabled regions which neither can sleep. ns_send() (the only caller of push_scqe()) has the following callers: - vcc_sendmsg() used as proto_ops::sendmsg is expected to be invoked in preemtible context. -> vcc->dev->ops->send() (ns_send()) - atm_vcc::send via atmdev_ops::send either directly (pointer copied by atm_init_aal34() or atm_init_aal5()) or via atm_send_aal0(). This is invoked by drivers (like br2684, clip, pppoatm, ...) which are called from net_device_ops::ndo_start_xmit with BH disabled. Add atmdev_ops::send_bh which is used by callers from BH context (atm_send_aal*()) and if this callback missing then ::send is used instead. Implement this callback in nicstar and use it to replace in_interrupt().

atm: nicstar: Unmap DMA on send error
The `skb' is mapped for DMA in ns_send() but does not unmap DMA in case
push_scqe() fails to submit the `skb'. The memory of the `skb' is
released so only the DMA mapping is leaking.
Unmap the DMA mapping in case push_scqe() failed.

atm: idt77252: avoid accessing the data mapped to streaming DMA
In queue_skb(), skb->data is mapped to streaming DMA on line 850:
dma_map_single(..., skb->data, ...);
Then skb->data is accessed on lines 862 and 863:
tbd->word_4 = (skb->data[0] << 24) | (skb->data[1] << 16) |
(skb->data[2] << 8) | (skb->data[3] << 0);
and on lines 893 and 894:
tbd->word_4 = (skb->data[0] << 24) | (skb->data[1] << 16) |
(skb->data[2] << 8) | (skb->data[3] << 0);
These accesses may cause data inconsistency between CPU cache and
hardware.
To fix this problem, the calculation result of skb->data is stored in a
local variable before DMA mapping, and then the driver accesses this
local variable instead of skb->data.

atm: fix atm_dev refcnt leaks in atmtcp_remove_persistent
atmtcp_remove_persistent() invokes atm_dev_lookup(), which returns a reference of atm_dev with increased refcount or NULL if fails. The refcount leaks issues occur in two error handling paths. If dev_data->persist is zero or PRIV(dev)->vcc isn't NULL, the function returns 0 without decreasing the refcount kept by a local variable, resulting in refcount leaks. Fix the issue by adding atm_dev_put() before returning 0 both when dev_data->persist is zero or PRIV(dev)->vcc isn't NULL.

treewide: Remove uninitialized_var() usage
Using uninitialized_var() is dangerous as it papers over real bugs[1] (or can in the future), and suppresses unrelated compiler warnings (e.g. "unused variable"). If the compiler thinks it is uninitialized, either simply initialize the variable or make compiler changes. In preparation for removing[2] the[3] macro[4], remove all remaining needless uses with the following script: git grep '\buninitialized_var\b' | cut -d: -f1 | sort -u | \ xargs perl -pi -e \ 's/\buninitialized_var\(([^\)]+)\)/\1/g; s:\s*/\* (GCC be quiet|to make compiler happy) \*/$::g;' drivers/video/fbdev/riva/riva_hw.c was manually tweaked to avoid pathological white-space. No outstanding warnings were found building allmodconfig with GCC 9.3.0 for x86_64, i386, arm64, arm, powerpc, powerpc64le, s390x, mips, sparc64, alpha, and m68k.

atm: Replace HTTP links with HTTPS ones
Rationale:
Reduces attack surface on kernel devs opening the links for MITM
as HTTPS traffic is much harder to manipulate.
Deterministic algorithm:
For each file:
If not .svg:
For each line:
If doesn't contain `\bxmlns\b`:
For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`:
If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`:
If both the HTTP and HTTPS versions
return 200 OK and serve the same content:
Replace HTTP with HTTPS.

mm: reorder includes after introduction of linux/pgtable.h
The replacement of <asm/pgrable.h> with <linux/pgtable.h> made the include
of the latter in the middle of asm includes. Fix this up with the aid of
the below script and manual adjustments here and there.
import sys

print "USAGE: %s <file> <header>" % (sys.argv[0])
