git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4
Pull ext4 bug fixes from Ted Ts'o:
- Fix regression caused by removing CONFIG_EXT3_FS when testing some
very old defconfigs
- Avoid a BUG_ON when opening a file on a maliciously corrupted file
system
- Avoid mm warnings when freeing a very large orphan file metadata
- Avoid a theoretical races between metadata writeback and checkpoints
(it's very hard to hit in practice, since the race requires that the
writeback take a very long time)
* tag 'ext4_for_linus-6.18-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/tytso/ext4:
Use CONFIG_EXT4_FS instead of CONFIG_EXT3_FS in all of the defconfigs
ext4: free orphan info with kvfree
ext4: detect invalid INLINE_DATA + EXTENTS flag combination
ext4, doc: fix and improve directory hash tree description
ext4: wait for ongoing I/O to complete before freeing blocks
jbd2: ensure that all ongoing I/O complete before freeing blocks

Commit d6ace46c82fd ("ext4: remove obsolete EXT3 config options")
removed the obsolete EXT3_CONFIG options, since it had been over a
decade since fs/ext3 had been removed. Unfortunately, there were a
number of defconfigs that still used CONFIG_EXT3_FS which the cleanup
commit didn't fix up. This led to a large number of defconfig test
builds to fail. Oops.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Add PCI_FIND_NEXT_CAP() and PCI_FIND_NEXT_EXT_CAP() macros that
take config space accessor functions.
Implement pci_find_capability(), pci_find_ext_capability(), and
dwc, dwc endpoint, and cadence capability search interfaces with
them (Hans Zhang)
- Leave parent unit address 0 in 'interrupt-map' so that when we
build devicetree nodes to describe PCI functions that contain
multiple peripherals, we can build this property even when
interrupt controllers lack 'reg' properties (Lorenzo Pieralisi)
- Add a Xeon 6 quirk to disable Extended Tags and limit Max Read
Request Size to 128B to avoid a performance issue (Ilpo Järvinen)
- Add sysfs 'serial_number' file to expose the Device Serial Number
(Matthew Wood)
- Fix pci_acpi_preserve_config() memory leak (Nirmoy Das)
Resource management:
- Align m68k pcibios_enable_device() with other arches (Ilpo
Järvinen)
- Remove sparc pcibios_enable_device() implementations that don't do
anything beyond what pci_enable_resources() does (Ilpo Järvinen)
- Remove mips pcibios_enable_resources() and use
pci_enable_resources() instead (Ilpo Järvinen)
- Clean up bridge window sizing and assignment (Ilpo Järvinen),
including:
- Leave non-claimed bridge windows disabled
- Enable bridges even if a window wasn't assigned because not all
windows are required by downstream devices
- Preserve bridge window type when releasing the resource, since
the type is needed for reassignment
- Consolidate selection of bridge windows into two new
interfaces, pbus_select_window() and
pbus_select_window_for_type(), so this is done consistently
- Compute bridge window start and end earlier to avoid logging
stale information
MSI:
- Add quirk to disable MSI on RDC PCI to PCIe bridges (Marcos Del Sol
Vives)
Error handling:
- Align AER with EEH by allowing drivers to request a Bus Reset on
Non-Fatal Errors (in addition to the reset on Fatal Errors that we
already do) (Lukas Wunner)
- If error recovery fails, emit FAILED_RECOVERY uevents for the
devices, not for the bridge leading to them.
This makes them correspond to BEGIN_RECOVERY uevents (Lukas Wunner)
- Align AER with EEH by calling err_handler.error_detected()
callbacks to notify drivers if error recovery fails (Lukas Wunner)
- Align AER with EEH by restoring device error_state to
pci_channel_io_normal before the err_handler.slot_reset() callback.
This is earlier than before the err_handler.resume() callback
(Lukas Wunner)
- Emit a BEGIN_RECOVERY uevent when driver's
err_handler.error_detected() requests a reset, as well as when it
says recovery is complete or can be done without a reset (Niklas
Schnelle)
- Align s390 with AER and EEH by emitting uevents during error
recovery (Niklas Schnelle)
- Align EEH with AER and s390 by emitting BEGIN_RECOVERY,
SUCCESSFUL_RECOVERY, or FAILED_RECOVERY uevents depending on the
result of err_handler.error_detected() (Niklas Schnelle)
- Fix a NULL pointer dereference in aer_ratelimit() when ACPI GHES
error information identifies a device without an AER Capability
(Breno Leitao)
- Update error decoding and TLP Log printing for new errors in
current PCIe base spec (Lukas Wunner)
- Update error recovery documentation to match the current code
and use consistent nomenclature (Lukas Wunner)
ASPM:
- Enable all ClockPM and ASPM states for devicetree platforms, since
there's typically no firmware that enables ASPM
This is a risky change that may uncover hardware or configuration
defects at boot-time rather than when users enable ASPM via sysfs
later. Booting with "pcie_aspm=off" prevents this enabling
(Manivannan Sadhasivam)
- Remove the qcom code that enabled ASPM (Manivannan Sadhasivam)
Power management:
- If a device has already been disconnected, e.g., by a hotplug
removal, don't bother trying to resume it to D0 when detaching the
driver.
This avoids annoying "Unable to change power state from D3cold to
D0" messages (Mario Limonciello)
- Ensure devices are powered up before config reads for
'max_link_width', 'current_link_speed', 'current_link_width',
'secondary_bus_number', and 'subordinate_bus_number' sysfs files.
This prevents using invalid data (~0) in drivers or lspci and,
depending on how the PCIe controller reports errors, may avoid
error interrupts or crashes (Brian Norris)
Virtualization:
- Add rescan/remove locking when enabling/disabling SR-IOV, which
avoids list corruption on s390, where disabling SR-IOV also
generates hotplug events (Niklas Schnelle)
Peer-to-peer DMA:
- Free struct p2p_pgmap, not a member within it, in the
pci_p2pdma_add_resource() error path (Sungho Kim)
Endpoint framework:
- Document sysfs interface for BAR assignment of vNTB endpoint
functions (Jerome Brunet)
- Fix array underflow in endpoint BAR test case (Dan Carpenter)
- Skip endpoint IRQ test if the IRQ is out of range to avoid false
errors (Christian Bruel)
- Fix endpoint test case for controllers with fixed-size BARs smaller
than requested by the test (Marek Vasut)
- Restore inbound translation when disabling doorbell so the endpoint
doorbell test case can be run more than once (Niklas Cassel)
- Avoid a NULL pointer dereference when releasing DMA channels in
endpoint DMA test case (Shin'ichiro Kawasaki)
- Convert tegra194 interrupt number to MSI vector to fix endpoint
Kselftest MSI_TEST test case (Niklas Cassel)
- Reset tegra194 BARs when running in endpoint mode so the BAR tests
don't overwrite the ATU settings in BAR4 (Niklas Cassel)
- Handle errors in tegra194 BPMP transactions so we don't mistakenly
skip future PERST# assertion (Vidya Sagar)
AMD MDB PCIe controller driver:
- Update DT binding example to separate PERST# to a Root Port stanza
to make multiple Root Ports possible in the future (Sai Krishna
Musham)
- Add driver support for PERST# being described in a Root Port
stanza, falling back to the host bridge if not found there (Sai
Krishna Musham)

- Enable the 3.3V Vaux supply if available so devices can request
wakeup with either Beacon or WAKE# (Richard Zhu)
MediaTek PCIe Gen3 controller driver:
- Add optional sys clock ready time setting to avoid sys_clk_rdy
signal glitching in MT6991 and MT8196 (AngeloGioacchino Del Regno)
- Add DT binding and driver support for MT6991 and MT8196
(AngeloGioacchino Del Regno)
NVIDIA Tegra PCIe controller driver:
- When asserting PERST#, disable the controller instead of mistakenly
disabling the PLL twice (Nagarjuna Kristam)
- Convert struct tegra_msi mask_lock to raw spinlock to avoid a lock
nesting error (Marek Vasut)
Qualcomm PCIe controller driver:
- Select PCI Power Control Slot driver so slot voltage rails can be
turned on/off if described in Root Port devicetree node (Qiang Yu)
- Parse only PCI bridge child nodes in devicetree, skipping unrelated
nodes such as OPP (Operating Performance Points), which caused
probe failures (Krishna Chaitanya Chundru)
- Add 8.0 GT/s and 32.0 GT/s equalization settings (Ziyue Zhang)
- Consolidate Root Port 'phy' and 'reset' properties in struct
qcom_pcie_port, regardless of whether we got them from the Root
Port node or the host bridge node (Manivannan Sadhasivam)
- Fetch and map the ELBI register space in the DWC core rather than
in each driver individually (Krishna Chaitanya Chundru)
- Enable ECAM mechanism in DWC core by setting up iATU with 'CFG
Shift Feature' and use this in the qcom driver (Krishna Chaitanya
Chundru)
- Add SM8750 compatible to qcom,pcie-sm8550.yaml (Krishna Chaitanya
Chundru)
- Update qcom,pcie-x1e80100.yaml to allow fifth PCIe host on Qualcomm
Glymur, which is compatible with X1E80100 but doesn't have the
cnoc_sf_axi clock (Qiang Yu)

- Pass the correct IRQ domain to generic_handle_domain_irq() to fix a
regression when converting to msi_create_parent_irq_domain()
(Claudiu Beznea)
- Drop the spinlock protecting the PMSR register - it's no longer
required since pci_lock already serializes accesses (Marek Vasut)
- Convert struct rcar_msi mask_lock to raw spinlock to avoid a lock
nesting error (Marek Vasut)
SOPHGO PCIe controller driver:
- Check for existence of struct cdns_pcie.ops before using it to
allow Cadence drivers that don't need to supply ops (Chen Wang)
- Add DT binding and driver for the SOPHGO SG2042 PCIe controller
(Chen Wang)

- Update pinctrl documentation of initial states and use in runtime
suspend/resume (Christian Bruel)
- Add pinctrl_pm_select_init_state() for use by stm32 driver, which
needs it during resume (Christian Bruel)
- Add devicetree bindings and drivers for the STMicroelectronics
STM32MP25 in host and endpoint modes (Christian Bruel)
Synopsys DesignWare PCIe controller driver:
- Add support for x16 in devicetree 'num-lanes' property (Konrad
Dybcio)
- Verify that if DT specifies a single IRQ for all eDMA channels, it
is named 'dma' (Niklas Cassel)

Vadapalli)
- Power controller off before configuring the glue layer so the

Vadapalli)
TI Keystone PCIe controller driver:
- Use devm_request_irq() so 'ks-pcie-error-irq' is freed when driver
exits with error (Siddharth Vadapalli)

PCIe devices to specific regions of host memory, to the ti,am65
binding (Jan Kiszka)

Pull networking updates from Paolo Abeni:
"Core & protocols:
- Improve drop account scalability on NUMA hosts for RAW and UDP
sockets and the backlog, almost doubling the Pps capacity under DoS
- Optimize the UDP RX performance under stress, reducing contention,
revisiting the binary layout of the involved data structs and
implementing NUMA-aware locking. This improves UDP RX performance
by an additional 50%, even more under extreme conditions
- Add support for PSP encryption of TCP connections; this mechanism
has some similarities with IPsec and TLS, but offers superior HW
offloads capabilities
- Ongoing work to support Accurate ECN for TCP. AccECN allows more
than one congestion notification signal per RTT and is a building
block for Low Latency, Low Loss, and Scalable Throughput (L4S)
- Reorganize the TCP socket binary layout for data locality, reducing
the number of touched cachelines in the fastpath
- Refactor skb deferral free to better scale on large multi-NUMA
hosts, this improves TCP and UDP RX performances significantly on
such HW
- Increase the default socket memory buffer limits from 256K to 4M to
better fit modern link speeds
- Improve handling of setups with a large number of nexthop, making
dump operating scaling linearly and avoiding unneeded
synchronize_rcu() on delete
- Improve bridge handling of VLAN FDB, storing a single entry per
bridge instead of one entry per port; this makes the dump order of
magnitude faster on large switches
- Restore IP ID correctly for encapsulated packets at GSO
segmentation time, allowing GRO to merge packets in more scenarios
- Improve netfilter matching performance on large sets
- Improve MPTCP receive path performance by leveraging recently
introduced core infrastructure (skb deferral free) and adopting
recent TCP autotuning changes
- Allow bridges to redirect to a backup port when the bridge port is
administratively down
- Introduce MPTCP 'laminar' endpoint that con be used only once per
connection and simplify common MPTCP setups
- Add RCU safety to dst->dev, closing a lot of possible races
- A significant crypto library API for SCTP, MPTCP and IPv6 SR,

Pull block updates from Jens Axboe:
- NVMe pull request via Keith:
- FC target fixes (Daniel)
- Authentication fixes and updates (Martin, Chris)
- Admin controller handling (Kamaljit)
- Target lockdep assertions (Max)
- Keep-alive updates for discovery (Alastair)
- Suspend quirk (Georg)
- MD pull request via Yu:
- Add support for a lockless bitmap.
A key feature for the new bitmap are that the IO fastpath is
lockless. If a user issues lots of write IO to the same bitmap
bit in a short time, only the first write has additional overhead
to update bitmap bit, no additional overhead for the following
writes.
By supporting only resync or recover written data, means in the
case creating new array or replacing with a new disk, there is no
need to do a full disk resync/recovery.
- Switch ->getgeo() and ->bios_param() to using struct gendisk rather
than struct block_device.
- Rust block changes via Andreas. This series adds configuration via
configfs and remote completion to the rnull driver. The series also
includes a set of changes to the rust block device driver API: a few
cleanup patches, and a few features supporting the rnull changes.
The series removes the raw buffer formatting logic from
`kernel::block` and improves the logic available in `kernel::string`
to support the same use as the removed logic.
- floppy arch cleanups
- Reduce the number of dereferencing needed for ublk commands
- Restrict supported sockets for nbd. Mostly done to eliminate a class
of issues perpetually reported by syzbot, by using nonsensical socket
setups.
- A few s390 dasd block fixes
- Fix a few issues around atomic writes
- Improve DMA interation for integrity requests
- Improve how iovecs are treated with regards to O_DIRECT aligment
constraints.
We used to require each segment to adhere to the constraints, now
only the request as a whole needs to.
- Clean up and improve p2p support, enabling use of p2p for metadata
payloads
- Improve locking of request lookup, using SRCU where appropriate
- Use page references properly for brd, avoiding very long RCU sections
- Fix ordering of recursively submitted IOs

Pull crypto library updates from Eric Biggers:
- Add a RISC-V optimized implementation of Poly1305. This code was
written by Andy Polyakov and contributed by Zhihang Shao.
- Migrate the MD5 code into lib/crypto/, and add KUnit tests for MD5.
Yes, it's still the 90s, and several kernel subsystems are still
using MD5 for legacy use cases. As long as that remains the case,
it's helpful to clean it up in the same way as I've been doing for
other algorithms.
Later, I plan to convert most of these users of MD5 to use the new
MD5 library API instead of the generic crypto API.
- Simplify the organization of the ChaCha, Poly1305, BLAKE2s, and
Curve25519 code.
Consolidate these into one module per algorithm, and centralize the
configuration and build process. This is the same reorganization that
has already been successful for SHA-1 and SHA-2.
- Remove the unused crypto_kpp API for Curve25519.
- Migrate the BLAKE2s and Curve25519 self-tests to KUnit.
- Always enable the architecture-optimized BLAKE2s code.

bcachefs was marked 'externally maintained' in 6.17 but the code
remained to make the transition smoother.
It's now a DKMS module, making the in-kernel code stale, so remove
it to avoid any version confusion.

The include/generated/asm-offsets.h is generated in Kbuild during
compiling from arch/SRCARCH/kernel/asm-offsets.c. When we want to
generate another similar offset header file, circular dependency can
happen.
For example, we want to generate a offset file include/generated/test.h,
which is included in include/sched/sched.h. If we generate asm-offsets.h
first, it will fail, as include/sched/sched.h is included in asm-offsets.c
and include/generated/test.h doesn't exist; If we generate test.h first,
it can't success neither, as include/generated/asm-offsets.h is included
by it.
In x86_64, the macro COMPILE_OFFSETS is used to avoid such circular
dependency. We can generate asm-offsets.h first, and if the
COMPILE_OFFSETS is defined, we don't include the "generated/test.h".
And we define the macro COMPILE_OFFSETS for all the asm-offsets.c for this
purpose.

m68k has a resource enable (check) loop in its pcibios_enable_device()
which for some reason differs from pci_enable_resources(). This could lead
to inconsistencies in behavior, especially now as pci_enable_resources()
and the bridge window resource flags behavior are going to be altered by
upcoming changes.
The check for !r->start && r->end is already covered by the more generic
checks done in pci_enable_resources().
The entire pcibios_enable_device() suspiciously looks copy-paste from some
other arch as also indicated by the preceding comment. However, it also
enables PCI_COMMAND_IO | PCI_COMMAND_MEMORY always for bridges. It is not
clear why that is being done as the commit e93a6bbeb5a5 ("m68k: common PCI
support definitions and code") introducing this code states "Nothing
specific to any PCI implementation in any m68k class CPU hardware yet".
Replace the resource enable loop with a call to pci_enable_resources() and
adjust the Command Register afterwards as it's unclear if that is necessary
or not so keep it for now.

The function signatures of the m68k-optimized implementations of the
find_{first,next}_{,zero_}bit() helpers do not match the generic
variants.
Fix this by changing all non-pointer inputs and outputs to "unsigned

While tracking down a problem where constant expressions used by
BUILD_BUG_ON() suddenly stopped working[1], we found that an added static
initializer was convincing the compiler that it couldn't track the state
of the prior statically initialized value. Tracing this down found that
ffs() was used in the initializer macro, but since it wasn't marked with
__attribute__const__, the compiler had to assume the function might
change variable states as a side-effect (which is not true for ffs(),
which provides deterministic math results).
Add missing __attribute_const__ annotations to M68K's implementations
of ffs(), __ffs(), fls(), __fls(), and ffz() functions. These are
pure mathematical functions that always return the same result for
the same input with no side effects, making them eligible for compiler
optimization.
Build tested ARCH=m68k defconfig with GCC m68k-linux-gnu 14.2.0.

Curve25519 has both a library API and a crypto_kpp API. However, the
crypto_kpp API for Curve25519 had no users outside crypto/testmgr.c.
I.e., no non-test code ever passed "curve25519" to crypto_alloc_kpp().
Remove this unused code. We'll instead focus on the Curve25519 library
API (<crypto/curve25519.h>), which is a simpler and easier-to-use API
and is the API that is actually being used.

With the introduction of clone3 in commit 7f192e3cd316 ("fork: add
clone3") the effective bit width of clone_flags on all architectures was
increased from 32-bit to 64-bit, with a new type of u64 for the flags.
However, for most consumers of clone_flags the interface was not
changed from the previous type of unsigned long.
While this works fine as long as none of the new 64-bit flag bits
(CLONE_CLEAR_SIGHAND and CLONE_INTO_CGROUP) are evaluated, this is still
undesirable in terms of the principle of least surprise.
Thus, this commit fixes all relevant interfaces of the copy_thread
function that is called from copy_process to consistently pass
clone_flags as u64, so that no truncation to 32-bit integers occurs on
32-bit architectures.

We have only two users of fixed_phy_add(), both use address 0 and
ignore the return value. So simplify fixed_phy_add() accordingly.
Whilst at it, constify the fixed_phy_status configs.
Note:
fixed_phy_add() is a legacy function which shouldn't be used in new
code, as it's use may be problematic:
- No check whether a fixed phy exists already at the given address
- If fixed_phy_register() is called afterwards by any other driver,
then it will also use phy_addr 0, because fixed_phy_add() ignores
the ida which manages address assignment
Drivers using a fixed phy created by fixed_phy_add() in platform code,
should dynamically create a fixed phy with fixed_phy_register()
instead.

Instances are happier that way and it makes more sense anyway -
the only part of the result that is related to partition we are given
is the start sector, and that has been filled in by the caller.
Everything else is a function of the disk. Only one instance
(DASD) is ever looking at anything other than bdev->bd_disk and
that one is trivial to adjust.

Pull fileattr updates from Christian Brauner:
"This introduces the new file_getattr() and file_setattr() system calls
after lengthy discussions.
Both system calls serve as successors and extensible companions to
the FS_IOC_FSGETXATTR and FS_IOC_FSSETXATTR system calls which have
started to show their age in addition to being named in a way that
makes it easy to conflate them with extended attribute related
operations.
These syscalls allow userspace to set filesystem inode attributes on
special files. One of the usage examples is the XFS quota projects.
XFS has project quotas which could be attached to a directory. All new
inodes in these directories inherit project ID set on parent
directory.
The project is created from userspace by opening and calling
FS_IOC_FSSETXATTR on each inode. This is not possible for special
files such as FIFO, SOCK, BLK etc. Therefore, some inodes are left
with empty project ID. Those inodes then are not shown in the quota
accounting but still exist in the directory. This is not critical but
in the case when special files are created in the directory with
already existing project quota, these new inodes inherit extended
attributes. This creates a mix of special files with and without
attributes. Moreover, special files with attributes don't have a
possibility to become clear or change the attributes. This, in turn,
prevents userspace from re-creating quota project on these existing
files.
In addition, these new system calls allow the implementation of
additional attributes that we couldn't or didn't want to fit into the
legacy ioctls anymore"

qemu-system-m68k -M q800 has an old bug that causes the kernel to
occasionally complain about a soft lockup:
watchdog: BUG: soft lockup - CPU#0 stuck for 5107s!
There isn't any actual lockup. The via1 clocksource produced a large
jump in jiffies, causing the watchdog to detect a stale timestamp.
The 32-bit clocksource counter runs at 783360 Hz and its period is
about 5482 seconds. Applying the "nanosecond" approximation used in
get_timestamp() in kernel/watchdog.c then yields the duration reported
in the log message above (always 5107 or 5108 in my tests):
0xffffffff / VIA_CLOCK_FREQ * 10**9 / 2**30 = 5106.209 seconds
It is notoriously difficult to correctly emulate a MOS6522 VIA chip. So
it seems wise to document the VIA clocksource driver better, especially
those hardware behaviours which the kernel relies upon.

While the GCC and Clang compilers already define __ASSEMBLER__
automatically when compiling assembly code, __ASSEMBLY__ is a
macro that only gets defined by the Makefiles in the kernel.
This can be very confusing when switching between userspace
and kernelspace coding, or when dealing with uapi headers that
rather should use __ASSEMBLER__ instead. So let's standardize on
the __ASSEMBLER__ macro that is provided by the compilers now.
This is almost a completely mechanical patch (done with a simple
"sed -i" statement), with one comment tweaked manually in
arch/m68k/include/asm/mac_baboon.h (which was missing underscores).

When MACH_IS_MVME147, the boot console calls mvme147_scc_write() to
generate console output. That will continue to work even after
debug_cons_nputs() becomes unavailable so there's no need to
unregister the boot console.
Take the opportunity to remove a repeated MACH_IS_* test. Use the
actual .write method (instead of a wrapper) and test that pointer
instead. This means adding an unused parameter to debug_cons_nputs() for
consistency with the struct console API.
early_printk.c is only built when CONFIG_EARLY_PRINTK=y. As of late,
head.S is only built when CONFIG_MMU_MOTOROLA=y. So let the former symbol
depend on the latter, to obviate some ifdef conditionals.

Move the cursor position rightward after rendering the character,
not before. This avoids complications that arise when the recursive
console_putc call has to wrap the line and/or scroll the display.
This also fixes the linewrap bug that crops off the rightmost column.
When the cursor is at the bottom of the display, a linefeed will not
move the cursor position further downward. Instead, the display scrolls
upward. Avoid the repeated add/subtract sequence by way of a single
subtraction at the initialization of console_struct_num_rows.

The DCCP socket family has now been removed from this tree, see:
8bb3212be4b4 ("Merge branch 'net-retire-dccp-socket'")
Remove connection tracking and NAT support for this protocol, this
should not pose a problem because no DCCP traffic is expected to be seen
on the wire.
As for the code for matching on dccp header for iptables and nftables,
mark it as deprecated and keep it in place. Ruleset restoration is an
atomic operation. Without dccp matching support, an astray match on dccp
could break this operation leaving your computer with no policy in
place, so let's follow a more conservative approach for matches.
Add CONFIG_NFT_EXTHDR_DCCP which is set to 'n' by default to deprecate
dccp extension support. Similarly, label CONFIG_NETFILTER_XT_MATCH_DCCP
as deprecated too and also set it to 'n' by default.
Code to match on DCCP protocol from ebtables also remains in place, this
is just a few checks on IPPROTO_DCCP from _check() path which is
exercised when ruleset is loaded. There is another use of IPPROTO_DCCP
from the _check() path in the iptables multiport match. Another check
for IPPROTO_DCCP from the packet in the reject target is also removed.
So let's schedule removal of the dccp matching for a second stage, this
should not interfer with the dccp retirement since this is only matching
on the dccp header.

Introduce file_getattr() and file_setattr() syscalls to manipulate inode
extended attributes. The syscalls takes pair of file descriptor and
pathname. Then it operates on inode opened accroding to openat()
semantics. The struct file_attr is passed to obtain/change extended
attributes.
This is an alternative to FS_IOC_FSSETXATTR ioctl with a difference
that file don't need to be open as we can reference it with a path
instead of fd. By having this we can manipulated inode extended
attributes not only on regular files but also on special ones. This
is not possible with FS_IOC_FSSETXATTR ioctl as with special files
we can not call ioctl() directly on the filesystem inode using fd.
This patch adds two new syscalls which allows userspace to get/set
extended inode attributes on special files by using parent directory
and a path - *at() like syscall.
