fs/pidfs: make 'lsof' happy with our inode changes
pidfs started using much saner inodes in commit b28ddcc32d8f ("pidfs:
convert to path_from_stashed() helper"), but that exposed the fact that
lsof had some knowledge of just how odd our old anon_inode usage was.
For example, legacy anon_inodes hadn't even initialized the inode type
in the inode mode, so everything had a type of zero.
So sane tools like 'stat' would report these files as "weird file", but
'lsof' instead used that (together with the name of the link in proc) to
notice that it's an anonymous inode, and used it to detect pidfd files.
Let's keep our internal new sane inode model, but mask the file type
bits at 'stat()' time in the getattr() function we already have, and by
making the dentry name match what lsof expects too.
This keeps our internal models sane, but should make user space see the
same old odd behavior.

KEYS: trusted: Do not use WARN when encode fails
When asn1_encode_sequence() fails, WARN is not the correct solution.
1. asn1_encode_sequence() is not an internal function (located
in lib/asn1_encode.c).
2. Location is known, which makes the stack trace useless.
3. Results a crash if panic_on_warn is set.
It is also noteworthy that the use of WARN is undocumented, and it
should be avoided unless there is a carefully considered rationale to
use it.
Replace WARN with pr_err, and print the return value instead, which is
only useful piece of information.

"Online repair feature continues to be expanded. Also, we now support
delayed allocation for realtime devices which have an extent size that
is equal to filesystem's block size.
New code:
- Introduce Parent Pointer extended attribute for inodes
- Bring back delalloc support for realtime devices which have an
extent size that is equal to filesystem's block size
- Improve performance of log incompat feature handling
Online Repair:
- Implement atomic file content exchanges i.e. exchange ranges of
bytes between two files atomically
- Create temporary files to repair file-based metadata. This uses
atomic file content exchange facility to swap file fork mappings
between the temporary file and the metadata inode
- Allow callers of directory/xattr code to set an explicit owner
number to be written into the header fields of any new blocks that
are created. This is required to avoid walking every block of the
new structure and modify their ownership during online repair
- Repair more data structures:
- Extended attributes
- Inode unlinked state
- Directories
- Symbolic links
- AGI's unlinked inode list
- Parent pointers
- Move Orphan files to lost and found directory
- Fixes for Inode repair functionality
- Introduce a new sub-AG FITRIM implementation to reduce the duration
for which the AGF lock is held
- Updates for the design documentation
- Use Parent Pointers to assist in checking directories, parent
pointers, extended attributes, and link counts
Fixes:
- Prevent userspace from reading invalid file data due to incorrect.
updation of file size when performing a non-atomic clone operation
- Minor fixes to online repair
- Fix confusing return values from xfs_bmapi_write()
- Fix an out of bounds access due to incorrect h_size during log
recovery
- Defer upgrading the extent counters in xfs_reflink_end_cow_extent()
until we know we are going to modify the extent mapping
- Remove racy access to if_bytes check in
xfs_reflink_end_cow_extent()
- Fix sparse warnings
Cleanups:
- Hold inode locks on all files involved in a rename until the
completion of the operation. This is in preparation for the parent
pointers patchset where parent pointers are applied in a separate
chained update from the actual directory update
- Compile out v4 support when disabled
- Cleanup xfs_extent_busy_clear()

These kinds of patches are only making the code worse.
Compilers don't care about the unnecessary check, but removing it makes
the code less obvious to a human. The declaration of 'len' is more than
80 lines earlier, so a human won't easily see that 'len' is of an
unsigned type, so to a human the range check that checks against zero is
much more explicit and obvious.
Any tool that complains about a range check like this just because the
variable is unsigned is actively detrimental, and should be ignored.

Merge tag 'bcachefs-2024-05-19' of https://evilpiepirate.org/git/bcachefs
Pull bcachefs updates from Kent Overstreet:
- More safety fixes, primarily found by syzbot
- Run the upgrade/downgrade paths in nochnages mode. Nochanges mode is
primarily for testing fsck/recovery in dry run mode, so it shouldn't
change anything besides disabling writes and holding dirty metadata
in memory.
The idea here was to reduce the amount of activity if we can't write
anything out, so that bringing up a filesystem in "super ro" mode
would be more lilkely to work for data recovery - but norecovery is
the correct option for this.
- btree_trans->locked; we now track whether a btree_trans has any btree
nodes locked, and this is used for improved assertions related to
trans_unlock() and trans_relock(). We'll also be using it for
improving how we work with lockdep in the future: we don't want
lockdep to be tracking individual btree node locks because we take
too many for lockdep to track, and it's not necessary since we have a
cycle detector.
- Trigger improvements that are prep work for online fsck
- BTREE_TRIGGER_check_repair; this regularizes how we do some repair
work for extents that goes with running triggers in fsck, and fixes
some subtle issues with transaction restarts there.
- bch2_snapshot_equiv() has now been ripped out of fsck.c; snapshot
equivalence classes are for when snapshot deletion leaves behind
redundant snapshot nodes, but snapshot deletion now cleans this up
right away, so the abstraction doesn't need to leak.
- Improvements to how we resume writing to the journal in recovery. The
code for picking the new place to write when reading the journal is
greatly simplified and we also store the position in the superblock
for when we don't read the journal; this means that we preserve more
of the journal for list_journal debugging.
- Improvements to sysfs btree_cache and btree_node_cache, for debugging
memory reclaim.
- We now detect when we've blocked for 10 seconds on the allocator in
the write path and dump some useful info.
- Safety fixes for devices references: this is a big series that
changes almost all device lookups to properly check if the device
exists and take a reference to it.
Previously we assumed that if a bkey exists that references a device
then the device must exist, and this was enforced in .invalid
methods, but this was incorrect because it meant device removal
relied on accounting being correct to not leave keys pointing to
invalid devices, and that's not something we can assume.
Getting the "pointer to invalid device" checks out of our .invalid()
methods fixes some long standing device removal bugs; the only
outstanding bug with device removal now is a race between the discard
path and deleting alloc info, which should be easily fixed.
- The allocator now prefers not to expand the new
member_info.btree_allocated bitmap, meaning if repair ever requires
scanning for btree nodes (because of a corrupt interior nodes) we
won't have to scan the whole device(s).
- New coding style document, which among other things talks about the
correct usage of assertions

Instead we have new clk drivers for STM and Sophgo, with
Samsung^WGoogle in third for the diffstat because they introduced HSI0
and HSI2 clk drivers for Google's GS101 SoC (high speed interface
things like PCIe, UFS, and MMC).
Beyond those big diffs there's the usual updates to various clk
drivers for incorrect parent descriptions or mising
MODULE_DEVICE_TABLE()s, etc. Nothing in particular stands out as super
interesting here.
New Drivers:
- STM32MP257 SoC clk driver
- Airoha EN7581 SoC clk driver
- Sophgo CV1800B, CV1812H and SG2000 SoC clk driver
- Loongson-2k0500 and Loongson-2k2000 SoC clk driver

- Improve the output of timerlat top by adding a missing \n, and by
avoiding printing color-formatting characters where they are

- Improve timerlat auto-analysis output by replacing '\t' with spaces
to avoid copy-and-paste issues when reporting problems.
- Make the user-space (-u) option the default, as it is the most
complete test. Add a -k option to use the in-kernel workload.
- On timerlat top and hist, add a summary with the overall results.
For instance, the minimum value for all CPUs, the overall average
and the maximum value from all CPUs.
- timerlat hist was printing initial values (i.e., 0 as max, and ~0
as min) if the trace stopped before the first Ret-User event. This
problem was fixed by printing the " - " no value string to the
output if that was the case.
For all RTLA tools:
- Add a --warm-up <seconds> option, allowing the workload to run for
<seconds> before starting to collect results.
- Add a --trace-buffer-size option, allowing the user to set the
tracing buffer size for -t option. This option is mainly useful for
reducing the trace file. Now rtla depends on libtracefs >= 1.6.

Pull tracing user-event updates from Steven Rostedt:
- Minor update to the user_events interface
The ABI of creating a user event states that the fields are separated
by semicolons, and spaces should be ignored.
But the parsing expected at least one space to be there (which was
incorrect). Fix the reading of the string to handle fields separated
by semicolons but no space between them.
This does extend the API sightly as now "field;field" will now be
parsed and not cause an error. But it should not cause any regressions
as no logic should expect it to fail.
Note, that the logic that parses the event fields to create the
trace_event works with no spaces after the semi-colon. It is
the logic that tests against existing events that is inconsistent.
This causes registering an event without using spaces to succeed
if it doesn't exist, but makes the same call that tries to register
to the same event, but doesn't use spaces, fail.

Pull tracing ring buffer updates from Steven Rostedt:
"Add ring_buffer memory mappings.
The tracing ring buffer was created based on being mostly used with
the splice system call. It is broken up into page ordered sub-buffers
and the reader swaps a new sub-buffer with an existing sub-buffer
that's part of the write buffer. It then has total access to the
swapped out sub-buffer and can do copyless movements of the memory
into other mediums (file system, network, etc).
The buffer is great for passing around the ring buffer contents in the
kernel, but is not so good for when the consumer is the user space
task itself.
A new interface is added that allows user space to memory map the ring
buffer. It will get all the write sub-buffers as well as reader
sub-buffer (that is not written to). It can send an ioctl to change
which sub-buffer is the new reader sub-buffer.
The ring buffer is read only to user space. It only needs to call the
ioctl when it is finished with a sub-buffer and needs a new sub-buffer
that the writer will not write over.
A self test program was also created for testing and can be used as an
example for the interface to user space. The libtracefs (external to
the kernel) also has code that interacts with this, although it is
disabled until the interface is in a official release. It can be
enabled by compiling the library with a special flag. This was used
for testing applications that perform better with the buffer being
mapped.
Memory mapped buffers have limitations. The main one is that it can
not be used with the snapshot logic. If the buffer is mapped,
snapshots will be disabled. If any logic is set to trigger snapshots
on a buffer, that buffer will not be allowed to be mapped"

l2tp: fix ICMP error handling for UDP-encap sockets
Since commit a36e185e8c85
("udp: Handle ICMP errors for tunnels with same destination port on both endpoints")
UDP's handling of ICMP errors has allowed for UDP-encap tunnels to
determine socket associations in scenarios where the UDP hash lookup
could not.
Subsequently, commit d26796ae58940
("udp: check udp sock encap_type in __udp_lib_err")
subtly tweaked the approach such that UDP ICMP error handling would be
skipped for any UDP socket which has encapsulation enabled.
In the case of L2TP tunnel sockets using UDP-encap, this latter
modification effectively broke ICMP error reporting for the L2TP
control plane.
To a degree this isn't catastrophic inasmuch as the L2TP control
protocol defines a reliable transport on top of the underlying packet
switching network which will eventually detect errors and time out.
However, paying attention to the ICMP error reporting allows for more
timely detection of errors in L2TP userspace, and aids in debugging
connectivity issues.
Reinstate ICMP error handling for UDP encap L2TP tunnels:
* implement struct udp_tunnel_sock_cfg .encap_err_rcv in order to allow
the L2TP code to handle ICMP errors;
* only implement error-handling for tunnels which have a managed
socket: unmanaged tunnels using a kernel socket have no userspace to
report errors back to;
* flag the error on the socket, which allows for userspace to get an
error such as -ECONNREFUSED back from sendmsg/recvmsg;
* pass the error into ip[v6]_icmp_error() which allows for userspace to
get extended error information via. MSG_ERRQUEUE.

by tg_get_cfs_burst() is microseconds, while in cpu_max_write(),
the burst unit used for calculation should be nanoseconds,
which leads to the bug.
To fix it, get the burst value directly from tg->cfs_bandwidth.burst.
I'm fine with either and that was my first thought here, too, but it did seem like
the comment was mostly placed there to justify the 'unexpected' high utilization
when explicitly passing FREQUENCY_UTIL and the need to clamp it then.
So removing did feel slightly more natural to me anyway.
So alternatively:

sched/fair: Fix initial util_avg calculation
Change se->load.weight to se_weight(se) in the calculation for the
initial util_avg to avoid unnecessarily inflating the util_avg by 1024
times.
The reason is that se->load.weight has the unit/scale as the scaled-up
load, while cfs_rg->avg.load_avg has the unit/scale as the true task
weight (as mapped directly from the task's nice/priority value). With
CONFIG_32BIT, the scaled-up load is equal to the true task weight. With
CONFIG_64BIT, the scaled-up load is 1024 times the true task weight.
Thus, the current code may inflate the util_avg by 1024 times. The
follow-up capping will not allow the util_avg value to go wild. But the
calculation should have the correct logic.

where the replacement length is 0. And using repl_len is wrong because
apply_alternatives() expands the buffer size to the length of the source
insn that is being patched, by padding it with one-byte NOPs:
for (; insn_buff_sz < a->instrlen; insn_buff_sz++)
insn_buff[insn_buff_sz] = 0x90;
Long story short: pass the length of the original instruction(s) as the
length of the temporary buffer which to optimize.
x86/boot: Address clang -Wimplicit-fallthrough in vsprintf()
After enabling -Wimplicit-fallthrough for the x86 boot code, clang
warns:
arch/x86/boot/printf.c:257:3: warning: unannotated fall-through between switch labels [-Wimplicit-fallthrough]
257 | case 'u':

Clang is a little more pedantic than GCC, which does not warn when
falling through to a case that is just break or return. Clang's version
is more in line with the kernel's own stance in deprecated.rst, which
states that all switch/case blocks must end in either break,
fallthrough, continue, goto, or return. Add the missing break to silence
the warning.

bonding: fix oops during rmmod
"rmmod bonding" causes an oops ever since commit cc317ea3d927 ("bonding:
remove redundant NULL check in debugfs function"). Here are the relevant
functions being called:
bonding_exit()
bond_destroy_debugfs()
debugfs_remove_recursive(bonding_debug_root);
bonding_debug_root = NULL; <--------- SET TO NULL HERE
bond_netlink_fini()
rtnl_link_unregister()
__rtnl_link_unregister()
unregister_netdevice_many_notify()
bond_uninit()
bond_debug_unregister()
(commit removed check for bonding_debug_root == NULL)
debugfs_remove()
simple_recursive_removal()
down_write() -> OOPS
However, reverting the bad commit does not solve the problem completely
because the original code contains a race that could cause the same
oops, although it was much less likely to be triggered unintentionally:
CPU2
echo -bond0 > /sys/class/net/bonding_masters
bond_uninit()
bond_debug_unregister()
if (!bonding_debug_root)
CPU1
bonding_debug_root = NULL;
So do NOT revert the bad commit (since the removed checks were racy
anyway), and instead change the order of actions taken during module
removal. The same oops can also happen if there is an error during
module init, so apply the same fix there.

net/ipv6: Fix route deleting failure when metric equals 0
Problem
=========
After commit 67f695134703 ("ipv6: Move setting default metric for routes"),
we noticed that the logic of assigning the default value of fc_metirc
changed in the ioctl process. That is, when users use ioctl(fd, SIOCADDRT,
rt) with a non-zero metric to add a route, then they may fail to delete a
route with passing in a metric value of 0 to the kernel by ioctl(fd,
SIOCDELRT, rt). But iproute can succeed in deleting it.
As a reference, when using iproute tools by netlink to delete routes with
a metric parameter equals 0, like the command as follows:
ip -6 route del fe80::/64 via fe81::5054:ff:fe11:3451 dev eth0 metric 0
the user can still succeed in deleting the route entry with the smallest
metric.
Root Reason
===========
After commit 67f695134703 ("ipv6: Move setting default metric for routes"),
When ioctl() pass in SIOCDELRT with a zero metric, rtmsg_to_fib6_config()
will set a defalut value (1024) to cfg->fc_metric in kernel, and in
ip6_route_del() and the line 4074 at net/ipv3/route.c, it will check by
if (cfg->fc_metric && cfg->fc_metric != rt->fib6_metric)
continue;
and the condition is true and skip the later procedure (deleting route)
because cfg->fc_metric != rt->fib6_metric. But before that commit,
cfg->fc_metric is still zero there, so the condition is false and it
will do the following procedure (deleting).
Solution
========
In order to keep a consistent behaviour across netlink() and ioctl(), we
should allow to delete a route with a metric value of 0. So we only do
the default setting of fc_metric in route adding.
