Merge branch 'libbpf: Resolve unambigous forward declarations'

Eduard Zingerman says:

====================

The patch-set is consists of the following parts:
- An update for libbpf's hashmap interface from void* -> void* to a
polymorphic one, allowing to use both long and void* keys and values
w/o additional casts. Interface functions are hidden behind
auxiliary macro that add casts as necessary.

This simplifies many use cases in libbpf as hashmaps there are
mostly integer to integer and required awkward looking incantations
like `(void *)(long)off` previously. Also includes updates for perf
as it copies map implementation from libbpf.

- A change to `lib/bpf/btf.c:btf__dedup` that adds a new pass named
"Resolve unambiguous forward declaration". This pass builds a
hashmap `name_off -> uniquely named struct or union` and uses it to
replace FWD types by structs or unions. This is necessary for corner
cases when FWD is not used as a part of some struct or union
definition de-duplicated by `btf_dedup_struct_types`.

The goal of the patch-set is to resolve forward declarations that
don't take part in type graphs comparisons if declaration name is
unambiguous.

Example:

CU #1:

struct foo; // standalone forward declaration
struct foo *some_global;

CU #2:

struct foo { int x; };
struct foo *another_global;

Currently the de-duplicated BTF for this example looks as follows:

[1] STRUCT 'foo' size=4 vlen=1 ...
[2] INT 'int' size=4 ...
[3] PTR '(anon)' type_id=1
[4] FWD 'foo' fwd_kind=struct
[5] PTR '(anon)' type_id=4

The goal of this patch-set is to simplify it as follows:

[1] STRUCT 'foo' size=4 vlen=1
'x' type_id=2 bits_offset=0
[2] INT 'int' size=4 bits_offset=0 nr_bits=32 encoding=SIGNED
[3] PTR '(anon)' type_id=1

For defconfig kernel with BTF enabled this removes 63 forward
declarations.

For allmodconfig kernel with BTF enabled this removes ~5K out of ~21K
forward declarations in ko objects. This unlocks some additional
de-duplication in ko objects, but impact is tiny: ~13K less BTF ids
out of ~2M.

Changelog:

- hashmap interface rework to allow use of integer and pointer keys

libbpf: Hashmap interface update to allow both long and void* keys/values

An update for libbpf's hashmap interface from void* -> void* to a
polymorphic one, allowing both long and void* keys and values.

This simplifies many use cases in libbpf as hashmaps there are mostly
integer to integer.

Perf copies hashmap implementation from libbpf and has to be
updated as well.

Changes to libbpf, selftests/bpf and perf are packed as a single
commit to avoid compilation issues with any future bisect.

Polymorphic interface is acheived by hiding hashmap interface
functions behind auxiliary macros that take care of necessary
type casts, for example:

#define hashmap_cast_ptr(p) \
({ \
_Static_assert((p) == NULL || sizeof(*(p)) == sizeof(long),\
#p " pointee should be a long-sized integer or a pointer"); \
(long *)(p); \
})

bool hashmap_find(const struct hashmap *map, long key, long *value);

#define hashmap__find(map, key, value) \
hashmap_find((map), (long)(key), hashmap_cast_ptr(value))

- hashmap__find macro casts key and value parameters to long
and long* respectively
- hashmap_cast_ptr ensures that value pointer points to a memory
of appropriate size.

This hack was suggested by Andrii Nakryiko in [1].
This is a follow up for [2].

Merge tag 'net-next-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next

Pull networking updates from Jakub Kicinski:
"Core:

- Introduce and use a single page frag cache for allocating small skb
heads, clawing back the 10-20% performance regression in UDP flood
test from previous fixes.

- Run packets which already went thru HW coalescing thru SW GRO. This
significantly improves TCP segment coalescing and simplifies
deployments as different workloads benefit from HW or SW GRO.

- Shrink the size of the base zero-copy send structure.

- Move TCP init under a new slow / sleepable version of DO_ONCE().

BPF:

- Add BPF-specific, any-context-safe memory allocator.

- Add helpers/kfuncs for PKCS#7 signature verification from BPF
programs.

- Define a new map type and related helpers for user space -> kernel
communication over a ring buffer (BPF_MAP_TYPE_USER_RINGBUF).

- Allow targeting BPF iterators to loop through resources of one
task/thread.

- Add ability to call selected destructive functions. Expose
crash_kexec() to allow BPF to trigger a kernel dump. Use
CAP_SYS_BOOT check on the loading process to judge permissions.

- Enable BPF to collect custom hierarchical cgroup stats efficiently
by integrating with the rstat framework.

- Support struct arguments for trampoline based programs. Only
structs with size <= 16B and x86 are supported.

- Invoke cgroup/connect{4,6} programs for unprivileged ICMP ping
sockets (instead of just TCP and UDP sockets).

- Add a helper for accessing CLOCK_TAI for time sensitive network
related programs.

- Support accessing network tunnel metadata's flags.

- Make TCP SYN ACK RTO tunable by BPF programs with TCP Fast Open.

- Add support for writing to Netfilter's nf_conn:mark.

Protocols:

- WiFi: more Extremely High Throughput (EHT) and Multi-Link Operation
(MLO) work (802.11be, WiFi 7).

- vsock: improve support for SO_RCVLOWAT.

- SMC: support SO_REUSEPORT.

- Netlink: define and document how to use netlink in a "modern" way.
Support reporting missing attributes via extended ACK.

- IPSec: support collect metadata mode for xfrm interfaces.

- TCPv6: send consistent autoflowlabel in SYN_RECV state and RST
packets.

- TCP: introduce optional per-netns connection hash table to allow
better isolation between namespaces (opt-in, at the cost of memory
and cache pressure).

- MPTCP: support TCP_FASTOPEN_CONNECT.

- Add NEXT-C-SID support in Segment Routing (SRv6) End behavior.

- Adjust IP_UNICAST_IF sockopt behavior for connected UDP sockets.

- Open vSwitch:
- Allow specifying ifindex of new interfaces.
- Allow conntrack and metering in non-initial user namespace.

- TLS: support the Korean ARIA-GCM crypto algorithm.

- Remove DECnet support.

Driver API:

- Allow selecting the conduit interface used by each port in DSA
switches, at runtime.

- Ethernet Power Sourcing Equipment and Power Device support.

- Add tc-taprio support for queueMaxSDU parameter, i.e. setting per
traffic class max frame size for time-based packet schedules.

- Support PHY rate matching - adapting between differing host-side
and link-side speeds.

- Introduce QUSGMII PHY mode and 1000BASE-KX interface mode.

- Validate OF (device tree) nodes for DSA shared ports; make
phylink-related properties mandatory on DSA and CPU ports.
Enforcing more uniformity should allow transitioning to phylink.

- Require that flash component name used during update matches one of
the components for which version is reported by info_get().

- Remove "weight" argument from driver-facing NAPI API as much as
possible. It's one of those magic knobs which seemed like a good
idea at the time but is too indirect to use in practice.

- Support offload of TLS connections with 256 bit keys.

Merge branch 'for-6.1/nvdimm' into libnvdimm-for-next

Add v6.1 content on top of some straggling updates that missed v6.0.

Merge branch 'Parameterize task iterators.'

Kui-Feng Lee says:

====================

Allow creating an iterator that loops through resources of one task/thread.

People could only create iterators

Merge branch 'Parameterize task iterators.'

Kui-Feng Lee says:

====================

Allow creating an iterator that loops through resources of one task/thread.

People could only create iterators to loop through all resources of
files, vma, and tasks in the system, even though they were interested in only the
resources of a specific task or process. Passing the additional
parameters, people can now create an iterator to go through all
resources or only the resources of a task.

Major Changes:

- Add new parameters in bpf_iter_link_info to indicate to go through
all tasks or to go through a specific task.

- Change the implementations of BPF iterators of vma, files, and
tasks to allow going through only the resources of a specific task.

- Provide the arguments of parameterized task iterators in
bpf_link_info.

Differences from v10:

- Check pid_alive() to avoid potential errors.

Differences from v9:

- Fix the boundary check of computing page_shift.

- Rewording the reason of checking and returning the same task.

Differences from v8:

- Fix uninitialized variable.

- Avoid redundant work of getting task from pid.

- Change format string to use %u instead of %d.

- Use the value of page_shift to compute correct offset in
bpf_iter_vm_offset.c.

Differences from v7:

- Travel the tasks of a process through task_group linked list
instead of traveling through the whole namespace.

Differences from v6:

- Add part 5 to make bpftool show the value of parameters.

- Change of wording of show_fdinfo() to show pid or tid instead of
always pid.

- Simplify error handling and naming of test cases.

Differences from v5:

- Use user-space tid/pid terminologies in bpf_iter_link_info and
bpf_link_info.

- Fix reference count

- Merge all variants to one 'u32 pid' in internal structs.
(bpf_iter_aux_info and bpf_iter_seq_task_common)

- Compare the result of get_uprobe_offset() with the implementation
with the vma iterators.

- Implement show_fdinfo.

Differences from v4:

- Remove 'type' from bpf_iter_link_info and bpf_link_info.

Link 33 is a task_file iterator with tid 1644. For now, only targets
of task, task_file and task_vma may be with tid or pid to filter out
tasks other than those belonging to a process (pid) or a thread (tid).
