perf dso: Reorder members to save space in 'struct dso'
Save 40 bytes and move from 8 to 7 cache lines. Make member dwfl
dependent on being a powerpc build. Squeeze bits of int/enum types
when appropriate. Remove holes/padding by reordering variables.

perf lock contention: Trim backtrace by skipping traceiter functions
The 'perf lock contention' program currently shows the caller of the locks
as __traceiter_contention_begin+0x??. This caller can be ignored, as it is
from the traceiter itself. Instead, it should show the real callers for
the locks.
When fiddling with the --stack-skip parameter, the actual callers for
the locks start to show up. However, just ignore the
__traceiter_contention_begin and the __traceiter_contention_end symbols
so the actual callers will show up.
Before this patch is applied:
sudo perf lock con -a -b -- sleep 3
contended total wait max wait avg wait type caller

Including fixes from CAN, netfilter, wireguard and IPsec.
Current release - regressions:
- rxrpc: fix use of page_frag_alloc_align(), it changed semantics
and we added a new caller in a different subtree
- xfrm: allow UDP encapsulation only in offload modes
Current release - new code bugs:
- tcp: fix refcnt handling in __inet_hash_connect()
- Revert "net: Re-use and set mono_delivery_time bit for userspace tstamp
packets", conflicted with some expectations in BPF uAPI
Previous releases - regressions:
- ipv4: raw: fix sending packets from raw sockets via IPsec tunnels
- devlink: fix devlink's parallel command processing
- veth: do not manipulate GRO when using XDP
- esp: fix bad handling of pages from page_pool
Previous releases - always broken:
- report RCU QS for busy network kthreads (with Paul McK's blessing)
- tcp/rds: fix use-after-free on netns with kernel TCP reqsk
- virt: vmxnet3: fix missing reserved tailroom with XDP
Misc:
- couple of build fixes for Documentation

perf/x86/rapl: Prefer struct_size() over open coded arithmetic
This is an effort to get rid of all multiplications from allocation functions in order to prevent integer overflows: https://www.kernel.org/doc/html/latest/process/deprecated.html#open-coded-arithmetic-in-allocator-arguments https://github.com/KSPP/linux/issues/160 As the "rapl_pmus" variable is a pointer to "struct rapl_pmus" and this structure ends in a flexible array: struct rapl_pmus { [...] struct rapl_pmu *pmus[] __counted_by(maxdie); }; the preferred way in the kernel is to use the struct_size() helper to do the arithmetic instead of the calculation "size + count * size" in the kzalloc() function.

locking/qspinlock: Always evaluate lockevent* non-event parameter once
The 'inc' parameter of lockevent_add() and the cond parameter of lockevent_cond_inc() are only evaluated when CONFIG_LOCK_EVENT_COUNTS is on. That can cause problem if those parameters are expressions with side effect like a "++". Fix this by evaluating those non-event parameters once even if CONFIG_LOCK_EVENT_COUNTS is off. This will also eliminate the need of the __maybe_unused attribute to the wait_early local variable in pv_wait_node().

dm-integrity: align the outgoing bio in integrity_recheck
It is possible to set up dm-integrity with smaller sector size than
the logical sector size of the underlying device. In this situation,
dm-integrity guarantees that the outgoing bios have the same alignment as
incoming bios (so, if you create a filesystem with 4k block size,
dm-integrity would send 4k-aligned bios to the underlying device).
This guarantee was broken when integrity_recheck was implemented.
integrity_recheck sends bio that is aligned to ic->sectors_per_block. So
if we set up integrity with 512-byte sector size on a device with logical
block size 4k, we would be sending unaligned bio. This triggered a bug in
one of our internal tests.
This commit fixes it by determining the actual alignment of the
incoming bio and then makes sure that the outgoing bio in
integrity_recheck has the same alignment.

exec: Fix NOMMU linux_binprm::exec in transfer_args_to_stack()
In NOMMU kernel the value of linux_binprm::p is the offset inside the temporary program arguments array maintained in separate pages in the linux_binprm::page. linux_binprm::exec being a copy of linux_binprm::p thus must be adjusted when that array is copied to the user stack. Without that adjustment the value passed by the NOMMU kernel to the ELF program in the AT_EXECFN entry of the aux array doesn't make any sense and it may break programs that try to access memory pointed to by that entry. Adjust linux_binprm::exec before the successful return from the transfer_args_to_stack(). Cc: <stable@vger.kernel.org> Fixes: |

perf probe: Add missing libgen.h header needed for using basename()
This prototype is obtained indirectly, by luck, from some other header
in probe-event.c in most systems, but recently exploded on alpine:edge:
8 13.39 alpine:edge : FAIL gcc version 13.2.1 20240309 (Alpine 13.2.1_git20240309)
util/probe-event.c: In function 'convert_exec_to_group':
util/probe-event.c:225:16: error: implicit declaration of function 'basename' [-Werror=implicit-function-declaration]
225 | ptr1 = basename(exec_copy);
| ^~~~~~~~
util/probe-event.c:225:14: error: assignment to 'char *' from 'int' makes pointer from integer without a cast [-Werror=int-conversion]
225 | ptr1 = basename(exec_copy);
| ^
cc1: all warnings being treated as errors
make[3]: *** [/git/perf-6.8.0/tools/build/Makefile.build:158: util] Error 2
Fix it by adding the libgen.h header where basename() is prototyped.
Fixes:

perf trace: Fix 'newfstatat'/'fstatat' argument pretty printing
There were needless two entries, one for 'newfstatat' and another for
'fstatat', keep just one and pretty print its 'flags' argument using the
fs_at_flags scnprintf that is also used by other FS syscalls such as
'stat', now:
