ocfs2: remove redundant l_next_free_rec check in __ocfs2_find_path()
The l_next_free_rec > l_count check after ocfs2_read_extent_block() in __ocfs2_find_path() is now redundant, as ocfs2_validate_extent_block() already performs this validation at block read time. Remove the duplicate check to avoid maintaining the same validation in two places.

ocfs2: validate extent block list fields during block read
Add extent list validation to ocfs2_validate_extent_block() so that
corrupted on-disk fields are caught early at block read time rather than
during extent tree traversal.
Two checks are added:
- l_count must equal the expected value from
ocfs2_extent_recs_per_eb(), catching blocks with a corrupted record
count before any array iteration.
- l_next_free_rec must not exceed l_count, preventing out-of-bounds
access when iterating over extent records.

ocfs2: validate dx_root extent list fields during block read
Patch series "ocfs2: consolidate extent list validation into block read callbacks". ocfs2 validates extent list fields (l_count, l_next_free_rec) at various points during extent tree traversal. This is fragile because each caller must remember to check for corrupted on-disk data before using it. This series moves those checks into the block read validation callbacks (ocfs2_validate_dx_root and ocfs2_validate_extent_block), so corrupted fields are caught early at block read time. Redundant post-read checks are then removed. This patch (of 4): Move the extent list l_count validation from ocfs2_dx_dir_lookup_rec() into ocfs2_validate_dx_root(), so that corrupted on-disk fields are caught early at block read time rather than during directory lookups. Additionally, add a l_next_free_rec <= l_count check to prevent out-of-bounds access when iterating over extent records. Both checks are skipped for inline dx roots (OCFS2_DX_FLAG_INLINE), which use dr_entries instead of dr_list.

ocfs2: fix use-after-free in ocfs2_fault() when VM_FAULT_RETRY
filemap_fault() may drop the mmap_lock before returning VM_FAULT_RETRY,
as documented in mm/filemap.c:
"If our return value has VM_FAULT_RETRY set, it's because the mmap_lock
may be dropped before doing I/O or by lock_folio_maybe_drop_mmap()."
When this happens, a concurrent munmap() can call remove_vma() and free
the vm_area_struct via RCU. The saved 'vma' pointer in ocfs2_fault() then
becomes a dangling pointer, and the subsequent trace_ocfs2_fault() call
dereferences it -- a use-after-free.
Fix this by saving ip_blkno as a plain integer before calling
filemap_fault(), and removing vma from the trace event. Since
ip_blkno is copied by value before the lock can be dropped, it
remains valid regardless of what happens to the vma or inode
afterward.

[CAUSE]
ocfs2_group_extend() assumes that the global bitmap inode block
returned from ocfs2_inode_lock() has already been validated and
BUG_ONs when the signature is not a dinode. That assumption is too
strong for crafted filesystems because the JBD2-managed buffer path
can bypass structural validation and return an invalid dinode to the
resize ioctl.
[FIX]
Validate the dinode explicitly in ocfs2_group_extend(). If the global
bitmap buffer does not contain a valid dinode, report filesystem
corruption with ocfs2_error() and fail the resize operation instead of
crashing the kernel.

[CAUSE]
ocfs2_bg_discontig_fix_result() iterates over bg->bg_list.l_recs[]
using l_next_free_rec as the upper bound without any sanity check:
for (i = 0; i < le16_to_cpu(bg->bg_list.l_next_free_rec); i++) {
rec = &bg->bg_list.l_recs[i];
l_next_free_rec is read directly from the on-disk group descriptor and
is trusted blindly. On a 4 KiB block device, bg_list.l_recs[] can hold
at most 235 entries (ocfs2_extent_recs_per_gd(sb)). A corrupted or
crafted filesystem image can set l_next_free_rec to an arbitrarily
large value, causing the loop to index past the end of the group
descriptor buffer_head data page and into an adjacent freed page.
[FIX]
Validate discontiguous bg_list.l_count against
ocfs2_extent_recs_per_gd(sb), then reject l_next_free_rec values that
exceed l_count. This keeps the on-disk extent list self-consistent and
matches how the rest of ocfs2 uses l_count as the extent-list bound.

checkpatch: exclude forward declarations of const structs
Limit checkpatch warnings for normally-const structs by excluding patterns consistent with forward declarations. For example, the forward declaration `struct regmap_access_table;` in a header file currently generates a warning recommending that it is generally declared as const; however, this would apply a useless type qualifier in the empty declaration `const struct regmap_access_table;`, and subsequently generate compiler warnings.

tools/accounting: handle truncated taskstats netlink messages
procacct and getdelays use a fixed receive buffer for taskstats generic netlink messages. A multi-threaded process exit can emit a single PID+TGID notification large enough to exceed that buffer on newer kernels. Switch to recvmsg() so MSG_TRUNC is detected explicitly, increase the message buffer size, and report truncated datagrams clearly instead of misparsing them as fatal netlink errors. Also print the taskstats version in debug output to make version mismatches easier to diagnose while inspecting taskstats traffic.

ocfs2/heartbeat: fix slot mapping rollback leaks on error paths
o2hb_map_slot_data() allocates hr_tmp_block, hr_slots, hr_slot_data, and pages in stages. If a later allocation fails, the current code returns without unwinding the earlier allocations. o2hb_region_dev_store() also leaves slot mapping resources behind when setup aborts, and it keeps hr_aborted_start/hr_node_deleted set across retries. That leaves stale state behind after a failed start. Factor the slot cleanup into o2hb_unmap_slot_data(), use it from both o2hb_map_slot_data() and o2hb_region_release(), and call it from the dev_store() rollback after stopping a started heartbeat thread. While freeing pages, clear each hr_slot_data entry as it is released, and reset the start state before each new setup attempt. This closes the slot mapping leak on allocation/setup failure paths and keeps failed setup attempts retryable.

printf: Compile the kunit test with DISABLE_BRANCH_PROFILING DISABLE_BRANCH_PROFILING
GCC < 12.1 can miscompile printf_kunit's errptr() test when branch
profiling is enabled. BUILD_BUG_ON(IS_ERR(PTR)) is a constant false
expression, but CONFIG_TRACE_BRANCH_PROFILING and
CONFIG_PROFILE_ALL_BRANCHES make the IS_ERR() path side-effectful.
GCC's IPA splitter can then outline the cold assert arm into
errptr.part.* and leave that clone with an unconditional
__compiletime_assert_*() call, causing a false build failure.
This started showing up after test_hashed() became a macro and moved its
local buffer into errptr(), which changed GCC's inlining and splitting
decisions enough to expose the compiler bug.
Workaround the problem by disabling the branch profiling for
printf_kunit.o. It is a straightforward and acceptable solution.
The workaround can be removed once the minimum GCC includes commit
76fe49423047 ("Fix tree-optimization/101941: IPA splitting out
function with error attribute"), which first shipped in GCC 12.1.

lib/crypto: mpi: Fix integer underflow in mpi_read_raw_from_sgl()
Yiming reports an integer underflow in mpi_read_raw_from_sgl() when subtracting "lzeros" from the unsigned "nbytes". For this to happen, the scatterlist "sgl" needs to occupy more bytes than the "nbytes" parameter and the first "nbytes + 1" bytes of the scatterlist must be zero. Under these conditions, the while loop iterating over the scatterlist will count more zeroes than "nbytes", subtract the number of zeroes from "nbytes" and cause the underflow. When commit |

Pull pid_namespace updates from Christian Brauner:
- pid_namespace: make init creation more flexible
Annotate ->child_reaper accesses with {READ,WRITE}_ONCE() to protect
the unlocked readers from cpu/compiler reordering, and enforce that
pid 1 in a pid namespace is always the first allocated pid (the
set_tid path already required this).
On top of that, allow opening pid_for_children before the pid
namespace init has been created. This lets one process create the pid
namespace and a different process create the init via setns(), which
makes clone3(set_tid) usable in all cases evenly and is particularly
useful to CRIU when restoring nested containers.
A new selftest covers both the basic create-pidns-then-init flow and
the cross-process variant, and a MAINTAINERS entry for the pid
namespace code is added.

Pull vfs mount updates from Christian Brauner:
- Add FSMOUNT_NAMESPACE flag to fsmount() that creates a new mount
namespace with the newly created filesystem attached to a copy of the
real rootfs. This returns a namespace file descriptor instead of an
O_PATH mount fd, similar to how OPEN_TREE_NAMESPACE works for
open_tree().
This allows creating a new filesystem and immediately placing it in a
new mount namespace in a single operation, which is useful for
container runtimes and other namespace-based isolation mechanisms.
This accompanies OPEN_TREE_NAMESPACE and avoids a needless detour via
OPEN_TREE_NAMESPACE to get the same effect. Will be especially useful
when you mount an actual filesystem to be used as the container
rootfs.
- Currently, creating a new mount namespace always copies the entire
mount tree from the caller's namespace. For containers and sandboxes
that intend to build their mount table from scratch this is wasteful:
they inherit a potentially large mount tree only to immediately tear
it down.
This series adds support for creating a mount namespace that contains
only a clone of the root mount, with none of the child mounts. Two
new flags are introduced:
- CLONE_EMPTY_MNTNS (0x400000000) for clone3(), using the 64-bit flag space
- UNSHARE_EMPTY_MNTNS (0x00100000) for unshare()
Both flags imply CLONE_NEWNS. The resulting namespace contains a
single nullfs root mount with an immutable empty directory. The
intended workflow is to then mount a real filesystem (e.g., tmpfs)
over the root and build the mount table from there.
- Allow MOVE_MOUNT_BENEATH to target the caller's rootfs, allowing to
switch out the rootfs without pivot_root(2).
The traditional approach to switching the rootfs involves
pivot_root(2) or a chroot_fs_refs()-based mechanism that atomically
updates fs->root for all tasks sharing the same fs_struct. This has
consequences for fork(), unshare(CLONE_FS), and setns().
This series instead decomposes root-switching into individually
atomic, locally-scoped steps:
fd_tree = open_tree(-EBADF, "/newroot", OPEN_TREE_CLONE | OPEN_TREE_CLOEXEC);
fchdir(fd_tree);
move_mount(fd_tree, "", AT_FDCWD, "/", MOVE_MOUNT_BENEATH | MOVE_MOUNT_F_EMPTY_PATH);
chroot(".");
umount2(".", MNT_DETACH);
Since each step only modifies the caller's own state, the
fork/unshare/setns races are eliminated by design.
A key step to making this possible is to remove the locked mount
restriction. Originally MOVE_MOUNT_BENEATH doesn't support mounting
beneath a mount that is locked. The locked mount protects the
underlying mount from being revealed. This is a core mechanism of
unshare(CLONE_NEWUSER | CLONE_NEWNS). The mounts in the new mount
namespace become locked. That effectively makes the new mount table
useless as the caller cannot ever get rid of any of the mounts no
matter how useless they are.
We can lift this restriction though. We simply transfer the locked
property from the top mount to the mount beneath. This works because
what we care about is to protect the underlying mount aka the parent.
The mount mounted between the parent and the top mount takes over the
job of protecting the parent mount from the top mount mount. This
leaves us free to remove the locked property from the top mount which
can consequently be unmounted:
unshare(CLONE_NEWUSER | CLONE_NEWNS)
and we inherit a clone of procfs on /proc then currently we cannot
unmount it as:
umount -l /proc
will fail with EINVAL because the procfs mount is locked.
After this series we can now do:
mount --beneath -t tmpfs tmpfs /proc
umount -l /proc
after which a tmpfs mount has been placed beneath the procfs mount.
The tmpfs mount has become locked and the procfs mount has become
unlocked.
This means you can safely modify an inherited mount table after
unprivileged namespace creation.
Afterwards we simply make it possible to move a mount beneath the
rootfs allowing to upgrade the rootfs.
Removing the locked restriction makes this very useful for containers
created with unshare(CLONE_NEWUSER | CLONE_NEWNS) to reshuffle an
inherited mount table safely and MOVE_MOUNT_BENEATH makes it possible
to switch out the rootfs instead of using the costly pivot_root(2).

Networking changes for 7.1.
Core & protocols
----------------
- Support HW queue leasing, allowing containers to be granted access
to HW queues for zero-copy operations and AF_XDP.
- Number of code moves to help the compiler with inlining.
Avoid output arguments for returning drop reason where possible.
- Rework drop handling within qdiscs to include more metadata
about the reason and dropping qdisc in the tracepoints.
- Remove the rtnl_lock use from IP Multicast Routing.
- Pack size information into the Rx Flow Steering table pointer
itself. This allows making the table itself a flat array of u32s,
thus making the table allocation size a power of two.
- Report TCP delayed ack timer information via socket diag.
- Add ip_local_port_step_width sysctl to allow distributing the randomly
selected ports more evenly throughout the allowed space.
- Add support for per-route tunsrc in IPv6 segment routing.
- Start work of switching sockopt handling to iov_iter.
- Improve dynamic recvbuf sizing in MPTCP, limit burstiness and avoid
buffer size drifting up.
- Support MSG_EOR in MPTCP.
- Add stp_mode attribute to the bridge driver for STP mode selection.
This addresses concerns about call_usermodehelper() usage.
- Remove UDP-Lite support (as announced in 2023).
- Remove support for building IPv6 as a module.
Remove the now unnecessary function calling indirection.
Cross-tree stuff
----------------
- Move Michael MIC code from generic crypto into wireless,
it's considered insecure but some WiFi networks still need it.
Netfilter
---------
- Switch nft_fib_ipv6 module to no longer need temporary dst_entry
object allocations by using fib6_lookup() + RCU.
Florian W reports this gets us ~13% higher packet rate.
- Convert IPVS's global __ip_vs_mutex to per-net service_mutex and
switch the service tables to be per-net. Convert some code that
walks the service lists to use RCU instead of the service_mutex.
- Add more opinionated input validation to lower security exposure.
- Make IPVS hash tables to be per-netns and resizable.
Wireless
--------
- Finished assoc frame encryption/EPPKE/802.1X-over-auth.
- Radar detection improvements.
- Add 6 GHz incumbent signal detection APIs.
- Multi-link support for FILS, probe response templates and
client probing.
- New APIs and mac80211 support for NAN (Neighbor Aware Networking,
aka Wi-Fi Aware) so less work must be in firmware.
Driver API
----------
- Add numerical ID for devlink instances (to avoid having to create
fake bus/device pairs just to have an ID). Support shared devlink
instances which span multiple PFs.
- Add standard counters for reporting pause storm events
(implement in mlx5 and fbnic).
- Add configuration API for completion writeback buffering
(implement in mana).
- Support driver-initiated change of RSS context sizes.
- Support DPLL monitoring input frequency (implement in zl3073x).
- Support per-port resources in devlink (implement in mlx5).

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Support HW queue leasing, allowing containers to be granted access
to HW queues for zero-copy operations and AF_XDP
- Number of code moves to help the compiler with inlining. Avoid
output arguments for returning drop reason where possible
- Rework drop handling within qdiscs to include more metadata about
the reason and dropping qdisc in the tracepoints
- Remove the rtnl_lock use from IP Multicast Routing
- Pack size information into the Rx Flow Steering table pointer
itself. This allows making the table itself a flat array of u32s,
thus making the table allocation size a power of two
- Report TCP delayed ack timer information via socket diag
- Add ip_local_port_step_width sysctl to allow distributing the
randomly selected ports more evenly throughout the allowed space
- Add support for per-route tunsrc in IPv6 segment routing
- Start work of switching sockopt handling to iov_iter
- Improve dynamic recvbuf sizing in MPTCP, limit burstiness and avoid
buffer size drifting up
- Support MSG_EOR in MPTCP
- Add stp_mode attribute to the bridge driver for STP mode selection.
This addresses concerns about call_usermodehelper() usage
- Remove UDP-Lite support (as announced in 2023)
- Remove support for building IPv6 as a module. Remove the now
unnecessary function calling indirection
Cross-tree stuff:
- Move Michael MIC code from generic crypto into wireless, it's
considered insecure but some WiFi networks still need it
Netfilter:
- Switch nft_fib_ipv6 module to no longer need temporary dst_entry
object allocations by using fib6_lookup() + RCU.
Florian W reports this gets us ~13% higher packet rate
- Convert IPVS's global __ip_vs_mutex to per-net service_mutex and

Pull bpf updates from Alexei Starovoitov:
- Welcome new BPF maintainers: Kumar Kartikeya Dwivedi, Eduard
Zingerman while Martin KaFai Lau reduced his load to Reviwer.
- Lots of fixes everywhere from many first time contributors. Thank you
All.
- Diff stat is dominated by mechanical split of verifier.c into
multiple components:
- backtrack.c: backtracking logic and jump history
- states.c: state equivalence
- cfg.c: control flow graph, postorder, strongly connected
components
- liveness.c: register and stack liveness
- fixups.c: post-verification passes: instruction patching, dead
code removal, bpf_loop inlining, finalize fastcall
8k line were moved. verifier.c still stands at 20k lines.
Further refactoring is planned for the next release.
- Replace dynamic stack liveness with static stack liveness based on
data flow analysis.
This improved the verification time by 2x for some programs and
equally reduced memory consumption. New logic is in liveness.c and
supported by constant folding in const_fold.c (Eduard Zingerman,
Alexei Starovoitov)
- Introduce BTF layout to ease addition of new BTF kinds (Alan Maguire)
- Use kmalloc_nolock() universally in BPF local storage (Amery Hung)
- Fix several bugs in linked registers delta tracking (Daniel Borkmann)
- Improve verifier support of arena pointers (Emil Tsalapatis)
- Improve verifier tracking of register bounds in min/max and tnum
domains (Harishankar Vishwanathan, Paul Chaignon, Hao Sun)
- Further extend support for implicit arguments in the verifier (Ihor
Solodrai)
- Add support for nop,nop5 instruction combo for USDT probes in libbpf
(Jiri Olsa)
- Support merging multiple module BTFs (Josef Bacik)
- Extend applicability of bpf_kptr_xchg (Kaitao Cheng)
- Retire rcu_trace_implies_rcu_gp() (Kumar Kartikeya Dwivedi)
- Support variable offset context access for 'syscall' programs (Kumar
Kartikeya Dwivedi)
- Migrate bpf_task_work and dynptr to kmalloc_nolock() (Mykyta
Yatsenko)
- Fix UAF in in open-coded task_vma iterator (Puranjay Mohan)

linux_kselftest-kunit-7.1-rc1
Fixes kunit tool to
-- terminate kernel under test on SIGINT when it catches SIGINT
to make sure the TTY isn't messed up and terminate the running
kernel.
-- recommend --raw_output=all when KTAP header isn't found in the kernel
output, it's useful to re-run the test with --raw_output=all to find
out the reasons why the test didn't complete.
-- skip stty when stdin is not a tty to avoid writing noise to stderr.
-- show suites when user runs --list_suites option instead of entire
list of tests to make the output user friendly and concise.

Modules changes for v7.1-rc1
Kernel symbol flags:
- Replace the separate *_gpl symbol sections (__ksymtab_gpl and
__kcrctab_gpl) with a unified symbol table and a new
__kflagstab section. This section stores symbol flags, such as
the GPL-only flag, as an 8-bit bitset for each exported symbol.
This is a cleanup that simplifies symbol lookup in the module
loader by avoiding table fragmentation and will allow a cleaner
way to add more flags later if needed.
Module signature UAPI:
- Move struct module_signature to the UAPI headers to allow reuse
by tools outside the kernel proper, such as kmod and
scripts/sign-file. This also renames a few constants for clarity
and drops unused signature types as preparation for hash-based
module integrity checking work that's in progress.
Sysfs:
- Add a /sys/module/<module>/import_ns sysfs attribute to show
the symbol namespaces imported by loaded modules. This makes it
easier to verify driver API access at runtime on systems that
care about such things (e.g. Android).
Cleanups and fixes:
- Force sh_addr to 0 for all sections in module.lds. This prevents
non-zero section addresses when linking modules with ld.bfd -r,
which confused elfutils.
- Fix a memory leak of charp module parameters on module unload
when the kernel is configured with CONFIG_SYSFS=n.
- Override the -EEXIST error code returned by module_init() to
userspace. This prevents confusion with the errno reserved by
the module loader to indicate that a module is already loaded.
- Simplify the warning message and drop the stack dump on positive
returns from module_init().
- Drop unnecessary extern keywords from function declarations and
synchronize parse_args() arguments with their implementation.

i2c: mediatek: add bus regulator control for power saving
Add conditional bus regulator enable/disable in mtk_i2c_transfer() to support I2C bus power gating for platforms that require it. This implementation: - Enables bus_regulator before clk_bulk_enable() if vbus-supply is defined - Disables bus_regulator after clk_bulk_disable() - Only activates when vbus-supply is provided in device tree - Has no impact on platforms without vbus-supply defined This approach provides power savings for platforms with an extra I2C bus regulator, while avoiding runtime PM complexity. Tested on MT8188.

i2c: pxa: handle 'Early Bus Busy' condition on Armada 3700
Under some circumstances I2C recovery fails on Armada 3700. At least on the Methode uDPU board, removing and replugging an SFP module fails often, like this: [ 36.953127] sfp sfp-eth1: module removed [ 38.468549] i2c i2c-1: i2c_pxa: timeout waiting for bus free [ 38.486960] sfp sfp-eth1: module MENTECHOPTO POS22-LDCC-KR rev 1.0 sn MNC208U90009 dc 200828 [ 38.496867] mvneta d0040000.ethernet eth1: unsupported SFP module: no common interface modes [ 38.521448] hwmon hwmon2: temp1_input not attached to any thermal zone [ 39.249196] sfp sfp-eth1: module removed ... [ 292.568799] sfp sfp-eth1: please wait, module slow to respond ... [ 625.208814] sfp sfp-eth1: failed to read EEPROM: -EREMOTEIO Note that the 'unsupported SFP module' messages are not relevant. The module is used only for testing the I2C recovery funcionality, because the error can be triggered easily with this specific one. Enabling debug in the i2c-pxa driver reveals the following: [ 82.034678] sfp sfp-eth1: module removed [ 90.008654] i2c i2c-1: slave_0x50 error: timeout with active message [ 90.015112] i2c i2c-1: msg_num: 2 msg_idx: 0 msg_ptr: 0 [ 90.020464] i2c i2c-1: IBMR: 00000003 IDBR: 000000a0 ICR: 000007e0 ISR: 00000802 [ 90.027906] i2c i2c-1: log: [ 90.030787] This continues until the retries are exhausted ... [ 110.192489] i2c i2c-1: slave_0x50 error: exhausted retries [ 110.198012] i2c i2c-1: msg_num: 2 msg_idx: 0 msg_ptr: 0 [ 110.203323] i2c i2c-1: IBMR: 00000003 IDBR: 000000a0 ICR: 000007e0 ISR: 00000802 [ 110.210810] i2c i2c-1: log: [ 110.213633] ... then the whole sequence starts again ... [ 115.368641] i2c i2c-1: slave_0x50 error: timeout with active message ... while finally the SFP core gives up: [ 671.975258] sfp sfp-eth1: failed to read EEPROM: -EREMOTEIO When we analyze the log, it can be seen that bit 1 and 11 is set in the ISR (Interface Status Register). Bit 1 indicates the ACK/NACK status, but the purpose of bit 11 is not documented in the driver code unfortunately. The 'Functional Specification' document of the Armada 3700 SoCs family however says that this bit indicates an 'Early Bus Busy' condition. The document also notes that whenever this bit is set, it is not possible to initiate a transaction on the I2C bus. The observed behaviour corresponds to this statement. Unfortunately, I2C recovery does not help as it never runs in this special case. Although the driver checks the busyness of the bus at several places, but since it does not consider the A3700 specific bit in these checks it can't determine the actual status of the bus correctly which results in the errors above. In order to fix the problem, add a new member to struct 'i2c_pxa' to store a controller specific bitmask containing the bits indicating the busy status, and use that in the code while checking the actual status of the bus. This ensures that the correct status can be determined on the Armada 3700 based devices without causing functional changes on devices based on other SoCs. With the change applied, the driver detects the busy condition, and runs the recovery process: [ 742.617312] i2c i2c-1: state:i2c_pxa_wait_bus_not_busy:449: ISR=00000802, ICR=000007e0, IBMR=03 [ 742.626099] i2c i2c-1: i2c_pxa: timeout waiting for bus free [ 742.631933] i2c i2c-1: recovery: resetting controller, ISR=0x00000802 [ 742.638421] i2c i2c-1: recovery: IBMR 0x00000003 ISR 0x00000000 This clears the EBB bit in the ISR register, so it makes it possible to initiate transactions on the I2C bus again. After this patch, the SFP module used for testing can be removed and replugged numerous times without causing the error described at the beginning. Previously, the error happened after a few such attempts. The patch has been tested also with the following kernel versions: 5.10.251, 5.15.201, 6.1.164, 6.6.127, 6.12.74, 6.14.11, 6.15.10, 6.16.1, 6.18.13, 6.19.3 It improves recovery on all of them.
