init_rx_sa() allocates relevant resource for rx_sa->stats and rx_sa->
key.tfm with alloc_percpu() and macsec_alloc_tfm(). When some error
occurs after init_rx_sa() is called in macsec_add_rxsa(), the function
released rx_sa with kfree() without releasing rx_sa->stats and rx_sa->
key.tfm, which will lead to a resource leak.
We should call macsec_rxsa_put() instead of kfree() to decrease the ref
count of rx_sa and release the relevant resource if the refcount is 0.
The same bug exists in macsec_add_txsa() for tx_sa as well. This patch
fixes the above two bugs.

macsec: fix config issues
The patch adding netlink support for XPN (commit 48ef50fa86
("macsec: Netlink support of XPN cipher suites (IEEE 802.1AEbw)"))
introduced several issues, including a kernel panic reported at [1].
Reproducing those bugs with upstream iproute is limited, since iproute
doesn't currently support XPN. I'm also working on this.

Currently, MACSEC_SA_ATTR_PN is handled inconsistently, sometimes as a
u32, sometimes forced into a u64 without checking the actual length of
the attribute. Instead, we can use nla_get_u64 everywhere, which will
read up to 64 bits into a u64, capped by the actual length of the
attribute coming from userspace.
This fixes several issues:
- the check in validate_add_rxsa doesn't work with 32-bit attributes
- the checks in validate_add_txsa and validate_upd_sa incorrectly
reject X << 32 (with X != 0)

IEEE 802.1AEbw-2013 (section 10.7.8) specifies that the maximum value
of the replay window is 2^30-1, to help with recovery of the upper
bits of the PN.
To avoid leaving the existing macsec device in an inconsistent state
if this test fails during changelink, reuse the cleanup mechanism
introduced for HW offload. This wasn't needed until now because
macsec_changelink_common could not fail during changelink, as
modifying the cipher suite was not allowed.
Finally, this must happen after handling IFLA_MACSEC_CIPHER_SUITE so
that secy->xpn is set.

Commit 48ef50fa86 added a test on tb_sa[MACSEC_SA_ATTR_PN], but
nothing guarantees that it's not NULL at this point. The same code was
added to macsec_add_txsa, but there it's not a problem because
validate_add_txsa checks that the MACSEC_SA_ATTR_PN attribute is
present.
Note: it's not possible to reproduce with iproute, because iproute
doesn't allow creating an SA without specifying the PN.

SCTP has supported memory accounting on tx path where 'sctp_wmem' is used

ip-sysctl.rst accordingly.

- Improve the description as Marcelo suggested.

tls_device_down takes a reference on all contexts it's going to move to
the degraded state (software fallback). If sk_destruct runs afterwards,
it can reduce the reference counter back to 1 and return early without
destroying the context. Then tls_device_down will release the reference
it took and call tls_device_free_ctx. However, the context will still
stay in tls_device_down_list forever. The list will contain an item,
memory for which is released, making a memory corruption possible.
Fix the above bug by properly removing the context from all lists before
any call to tls_device_free_ctx.

The mitigations for RETBleed are currently ineffective on x86_32 since
entry_32.S does not use the required macros. However, for an x86_32
target, the kconfig symbols for them are still enabled by default and
/sys/devices/system/cpu/vulnerabilities/retbleed will wrongly report
that mitigations are in place.
Make all of these symbols depend on X86_64, and only enable RETHUNK by
default on X86_64.

This reverts commit 4a41f453be.
This to-be-reverted commit was meant to apply a stricter rule for the
stack to enter pingpong mode. However, the condition used to check for
interactive session "before(tp->lsndtime, icsk->icsk_ack.lrcvtime)" is
jiffy based and might be too coarse, which delays the stack entering
pingpong mode.
We revert this patch so that we no longer use the above condition to
determine interactive session, and also reduce pingpong threshold to 1.

This pull request contains a pair of commits that fix 282d8998e9 ("srcu:
Prevent expedited GPs and blocking readers from consuming CPU"), which
was itself a fix to an SRCU expedited grace-period problem that could
prevent kernel live patching (KLP) from completing. That SRCU fix for
KLP introduced large (as in minutes) boot-time delays to embedded Linux
kernels running on qemu/KVM. These delays were due to the emulation of
certain MMIO operations controlling memory layout, which were emulated
with one expedited grace period per access. Common configurations
required thousands of boot-time MMIO accesses, and thus thousands of
boot-time expedited SRCU grace periods.
In these configurations, the occasional sleeps that allowed KLP to proceed
caused excessive boot delays. These commits preserve enough sleeps to
permit KLP to proceed, but few enough that the virtual embedded kernels
still boot reasonably quickly.
This represents a regression introduced in the v5.19 merge window,
and the bug is causing significant inconvenience, hence this pull request.

Sudip reports that alpha doesn't build properly, with errors like
include/asm-generic/tlb.h:401:1: error: redefinition of 'tlb_update_vma_flags'
401 | tlb_update_vma_flags(struct mmu_gather *tlb, struct vm_area_struct *vma)
| ^~~~~~~~~~~~~~~~~~~~
include/asm-generic/tlb.h:372:1: note: previous definition of 'tlb_update_vma_flags' with type 'void(struct mmu_gather *, struct vm_area_struct *)'
372 | tlb_update_vma_flags(struct mmu_gather *tlb, struct vm_area_struct *vma) { }
the cause being that We have this odd situation where some architectures
were never converted to the newer TLB flushing interfaces that have a
range for the flush. Instead people left them alone, and we have them
select the MMU_GATHER_NO_RANGE config option to make the tlb header
files account for this.
Peter Zijlstra cleaned some of these nasty header file games up in
commits
1e9fdf21a4 ("mmu_gather: Remove per arch tlb_{start,end}_vma()")
18ba064e42 ("mmu_gather: Let there be one tlb_{start,end}_vma() implementation")
but tlb_update_vma_flags() was left alone, and then commit b67fbebd4c
("mmu_gather: Force tlb-flush VM_PFNMAP vmas") ended up removing only
_one_ of the two stale duplicate dummy inline functions.
This removes the other stale one.
Somebody braver than me should try to remove MMU_GATHER_NO_RANGE
entirely, but it requires fixing up the oddball architectures that use
it: alpha, m68k, microblaze, nios2 and openrisc.
The fixups should be fairly straightforward ("fix the build errors it
exposes by adding the appropriate range arguments"), but the reason this
wasn't done in the first place is that so few people end up working on
those architectures. But it could be done one architecture at a time,
hint, hint.

Laurence reports:
"Kernel >5.18 on Zaurus has a bug where the power management code can't
talk to devices, emitting the following errors:
sharpsl-pm sharpsl-pm: Error: AC check failed: voltage -22.
sharpsl-pm sharpsl-pm: Charging Error!
sharpsl-pm sharpsl-pm: Warning: Cannot read main battery!
Looking at the recent changes, I found that commit 31455bbda2 ("spi:
pxa2xx_spi: Convert to use GPIO descriptors") replaced the deprecated
SPI chip select platform device code with a gpiod lookup table. However,
this didn't seem to work until I changed the `dev_id` member from the
device name to the bus id. I'm not entirely sure why this is necessary,
but I suspect it is related to the fact that in sysfs SPI devices are
attached under /sys/devices/.../dev_name/spi_master/spiB/spiB.C, rather
than directly to the device."
After reviewing the change I conclude that the same fix is needed
for all affected boards.

Commit 527701eda5 ("lib: Add a generic version of devmem_is_allowed()")
introduces the config symbol GENERIC_LIB_DEVMEM_IS_ALLOWED, but then
falsely refers to CONFIG_GENERIC_DEVMEM_IS_ALLOWED (note the missing LIB
in the reference) in ./include/asm-generic/io.h.
Luckily, ./scripts/checkkconfigsymbols.py warns on non-existing configs:
GENERIC_DEVMEM_IS_ALLOWED
Referencing files: include/asm-generic/io.h
The actual fix, though, is simply to not to make this function declaration
dependent on any kernel config. For architectures that intend to use
the generic version, the arch's 'select GENERIC_LIB_DEVMEM_IS_ALLOWED' will
lead to picking the function definition, and for other architectures, this
function is simply defined elsewhere.
The wrong '#ifndef' on a non-existing config symbol also always had the
same effect (although more by mistake than by intent). So, there is no
functional change.
Remove this broken and needless ifdef conditional.

zynqmp_get_error_info() writes 0 to the ECC_CLR_OFST register after
an interrupt for a {un-,}correctable error is raised, which disables
the error interrupts. Then the interrupt handler will be called only
once. Therefore, re-enable the error interrupt line at the end of
intr_handler() for v3.x Synopsys EDAC DDR.

Bitmap are "unsigned long", so use it instead of a "u32" to make things
more explicit.
While at it, remove some useless cast (and leading spaces) when using the
bitmap API.

While the if/then schemas mostly work, there's a few issues. The 'allOf'
schema will also be true if 'fixed-link' is not an array or object as a
false 'if' schema (without an 'else') will be true. In the array case
doesn't set the type (uint32-array) in the 'then' clause. In the node case,
'additionalProperties' is missing.
Rework the schema to use oneOf with each possible type.

====================
sysctl: Fix data-races around ipv4_net_table (Round 5).
This series fixes data-races around 15 knobs after tcp_dsack in
ipv4_net_table.
tcp_tso_win_divisor was skipped because it already uses READ_ONCE().
So, the final round for ipv4_net_table will start with tcp_pacing_ss_ratio.
