This isn't a hugely busy cycle for documentation, but a few significant
things still showed up:
- A documentation section for ARC processors
- Reworked and enhanced KUnit documentation
- The ability to pick your own theme for HTML builds; if the default
"Read the Docs" theme isn't ugly enough for you, you can now pick
an uglier one.
- More Chinese translation work
Plus the usual assortment of fixes and cleanups.

Pull workqueue updates from Tejun Heo: - The code around workqueue scheduler hooks got reorganized early 2019 which unfortuately introdued a couple subtle and rare race conditions where preemption can mangle internal workqueue state triggering a WARN and possibly causing a stall or at least delay in execution. Frederic fixed both early December and the fixes were sitting in for-5.16-fixes which I forgot to push. They are here now. I'll forward them to stable after they land. - The scheduler hook reorganization has more implicatoins for workqueue code in that the hooks are now more strictly synchronized and thus the interacting operations can become more straight-forward. Lai is in the process of simplifying workqueue code and this pull request contains some of the patches. * 'for-5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: workqueue: Remove the cacheline_aligned for nr_running workqueue: Move the code of waking a worker up in unbind_workers() workqueue: Remove schedule() in unbind_workers() workqueue: Remove outdated comment about exceptional workers in unbind_workers() workqueue: Remove the advanced kicking of the idle workers in rebind_workers() workqueue: Remove the outdated comment before wq_worker_sleeping() workqueue: Fix unbind_workers() VS wq_worker_sleeping() race workqueue: Fix unbind_workers() VS wq_worker_running() race workqueue: Upgrade queue_work_on() comment |

select: Fix indefinitely sleeping task in poll_schedule_timeout()
A task can end up indefinitely sleeping in do_select() ->
poll_schedule_timeout() when the following race happens:
TASK1 (thread1) TASK2 TASK1 (thread2)
do_select()
setup poll_wqueues table
with 'fd'
write data to 'fd'
pollwake()
table->triggered = 1
closes 'fd' thread1 is
waiting for
poll_schedule_timeout()
- sees table->triggered
table->triggered = 0
return -EINTR
loop back in do_select()
But at this point when TASK1 loops back, the fdget() in the setup of
poll_wqueues fails. So now so we never find 'fd' is ready for reading
and sleep in poll_schedule_timeout() indefinitely.
Treat an fd that got closed as a fd on which some event happened. This
makes sure cannot block indefinitely in do_select().
Another option would be to return -EBADF in this case but that has a
potential of subtly breaking applications that excercise this behavior
and it happens to work for them. So returning fd as active seems like a
safer choice.

sections: Fix __is_kernel() to include init ranges
With CONFIG_KALLSYMS_ALL=y, the function is_ksym_addr() is used to determine if a symbol is from inside the kernel range. For that the given symbol address is checked if it's inside the _stext to _end range. Although this is correct, some architectures (e.g. parisc) may have the init area before the _stext address and as such the check in is_ksym_addr() fails. By extending the range check to include the init section, __is_kernel() will now detect symbols in this range as well. This fixes an issue on parisc where addresses of kernel functions in init sections aren't resolved to their symbol names. Signed-off-by: Helge Deller <deller@gmx.de> |

parisc: Enable TOC (transfer of contents) feature unconditionally
Before this patch, the TOC code used a pre-allocated stack of 16kb for each possible CPU. That space overhead was the reason why the TOC feature wasn't enabled by default for 32-bit kernels. This patch rewrites the TOC code to use a per-cpu stack. That way we use much less memory now and as such we enable the TOC feature by default on all kernels. Additionally the dump of the registers and the stacktrace wasn't serialized, which led to multiple CPUs printing the stack backtrace at once which rendered the output unreadable. Now the backtraces are nicely serialized by a lock. Signed-off-by: Helge Deller <deller@gmx.de> |

netfilter: nf_tables: don't use 'data_size' uninitialized
Commit 2c865a8a28a1 ("netfilter: nf_tables: add rule blob layout") never
initialized the new 'data_size' variable.
I'm not sure how it ever worked, but it might have worked almost by
accident - gcc seems to occasionally miss these kinds of 'variable used
uninitialized' situations, but I've seen it do so because it ended up
zero-initializing them due to some other simplification.
But clang is very unhappy about it all, and correctly reports
net/netfilter/nf_tables_api.c:8278:4: error: variable 'data_size' is uninitialized when used here [-Werror,-Wuninitialized]
data_size += sizeof(*prule) + rule->dlen;
^~~~~~~~~
net/netfilter/nf_tables_api.c:8263:30: note: initialize the variable 'data_size' to silence this warning
unsigned int size, data_size;
^
= 0
1 error generated.
and this fix just initializes 'data_size' to zero before the loop.

or at least perform the freeing outside of the socket lock section
to decrease cross-CPU allocator work and improve latency.
- Add netdevice refcount tracking to locate sources of netdevice
and net namespace refcount leaks.
- Make Tx watchdog less intrusive - avoid pausing Tx and restarting
all queues from a single CPU removing latency spikes.
- Various small optimizations throughout the stack from Eric Dumazet.
- Make netdev->dev_addr[] constant, force modifications to go via
appropriate helpers to allow us to keep addresses in ordered data
structures.
- Replace unix_table_lock with per-hash locks, improving performance
of bind() calls.
- Extend skb drop tracepoint with a drop reason.
- Allow SO_MARK and SO_PRIORITY setsockopt under CAP_NET_RAW.
BPF
---
- New helpers:
- bpf_find_vma(), find and inspect VMAs for profiling use cases
- bpf_loop(), runtime-bounded loop helper trading some execution
time for much faster (if at all converging) verification
- bpf_strncmp(), improve performance, avoid compiler flakiness
- bpf_get_func_arg(), bpf_get_func_ret(), bpf_get_func_arg_cnt()
for tracing programs, all inlined by the verifier
- Support BPF relocations (CO-RE) in the kernel loader.
- Further the support for BTF_TYPE_TAG annotations.
- Allow access to local storage in sleepable helpers.
- Convert verifier argument types to a composable form with different
attributes which can be shared across types (ro, maybe-null).
- Prepare libbpf for upcoming v1.0 release by cleaning up APIs,
creating new, extensible ones where missing and deprecating those
to be removed.
Protocols
---------
- WiFi (mac80211/cfg80211):
- notify user space about long "come back in N" AP responses,
allow it to react to such temporary rejections
- allow non-standard VHT MCS 10/11 rates
- use coarse time in airtime fairness code to save CPU cycles
- Bluetooth:
- rework of HCI command execution serialization to use a common
queue and work struct, and improve handling errors reported
in the middle of a batch of commands
- rework HCI event handling to use skb_pull_data, avoiding packet
parsing pitfalls
- support AOSP Bluetooth Quality Report
- SMC:
- support net namespaces, following the RDMA model
- improve connection establishment latency by pre-clearing buffers
- introduce TCP ULP for automatic redirection to SMC
- Multi-Path TCP:
- support ioctls: SIOCINQ, OUTQ, and OUTQNSD
- support socket options: IP_TOS, IP_FREEBIND, IP_TRANSPARENT,
IPV6_FREEBIND, and IPV6_TRANSPARENT, TCP_CORK and TCP_NODELAY
- support cmsgs: TCP_INQ
- improvements in the data scheduler (assigning data to subflows)
- support fastclose option (quick shutdown of the full MPTCP
connection, similar to TCP RST in regular TCP)
- MCTP (Management Component Transport) over serial, as defined by
DMTF spec DSP0253 - "MCTP Serial Transport Binding".
Driver API
----------
- Support timestamping on bond interfaces in active/passive mode.
- Introduce generic phylink link mode validation for drivers which
don't have any quirks and where MAC capability bits fully express
what's supported. Allow PCS layer to participate in the validation.
Convert a number of drivers.
- Add support to set/get size of buffers on the Rx rings and size of
the tx copybreak buffer via ethtool.
- Support offloading TC actions as first-class citizens rather than
only as attributes of filters, improve sharing and device resource
utilization.
- WiFi (mac80211/cfg80211):
- support forwarding offload (ndo_fill_forward_path)
- support for background radar detection hardware
- SA Query Procedures offload on the AP side

Merge branch 'random-5.17-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random
Pull random number generator updates from Jason Donenfeld:
"These a bit more numerous than usual for the RNG, due to folks
resubmitting patches that had been pending prior and generally renewed
interest.
There are a few categories of patches in here:
1) Dominik Brodowski and I traded a series back and forth for a some
weeks that fixed numerous issues related to seeds being provided
at extremely early boot by the firmware, before other parts of the
kernel or of the RNG have been initialized, both fixing some
crashes and addressing correctness around early boot randomness.
One of these is marked for stable.
2) I replaced the RNG's usage of SHA-1 with BLAKE2s in the entropy
extractor, and made the construction a bit safer and more
standard. This was sort of a long overdue low hanging fruit, as we
were supposed to have phased out SHA-1 usage quite some time ago
(even if all we needed here was non-invertibility). Along the way
it also made extraction 131% faster. This required a bit of
Kconfig and symbol plumbing to make things work well with the
crypto libraries, which is one of the reasons why I'm sending you
this pull early in the cycle.
3) I got rid of a truly superfluous call to RDRAND in the hot path,
which resulted in a whopping 370% increase in performance.
4) Sebastian Andrzej Siewior sent some patches regarding PREEMPT_RT,
the full series of which wasn't ready yet, but the first two
preparatory cleanups were good on their own. One of them touches
files in kernel/irq/, which is the other reason why I'm sending
you this pull early in the cycle.
5) Other assorted correctness fixes from Eric Biggers, Jann Horn,
Mark Brown, Dominik Brodowski, and myself"
* 'random-5.17-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/crng/random:

ext4: don't use the orphan list when migrating an inode
We probably want to remove the indirect block to extents migration feature after a deprecation window, but until then, let's fix a potential data loss problem caused by the fact that we put the tmp_inode on the orphan list. In the unlikely case where we crash and do a journal recovery, the data blocks belonging to the inode being migrated are also represented in the tmp_inode on the orphan list --- and so its data blocks will get marked unallocated, and available for reuse. Instead, stop putting the tmp_inode on the oprhan list. So in the case where we crash while migrating the inode, we'll leak an inode, which is not a disaster. It will be easily fixed the next time we run fsck, and it's better than potentially having blocks getting claimed by two different files, and losing data as a result.

ext4: allow to change s_last_trim_minblks via sysfs
Ext4 has an optimization mechanism for batched disacrd (FITRIM) that should help speed up subsequent calls of FITRIM ioctl by skipping the groups that were previously trimmed. However because the FITRIM allows to set the minimum size of an extent to trim, ext4 stores the last minimum extent size and only avoids trimming the group if it was previously trimmed with minimum extent size equal to, or smaller than the current call. There is currently no way to bypass the optimization without umount/mount cycle. This becomes a problem when the file system is live migrated to a different storage, because the optimization will prevent possibly useful discard calls to the storage. Fix it by exporting the s_last_trim_minblks via sysfs interface which will allow us to set the minimum size to the number of blocks larger than subsequent FITRIM call, effectively bypassing the optimization. By setting the s_last_trim_minblks to ULONG_MAX the optimization will be effectively cleared regardless of the previous state, or file system configuration. For example: getconf ULONG_MAX > /sys/fs/ext4/dm-1/last_trim_minblks Signed-off-by: Lukas Czerner <lczerner@redhat.com> Reported-by: Laurent GUERBY <laurent@guerby.net> Reviewed-by: Andreas Dilger <adilger@dilger.ca> Link: https://lore.kernel.org/r/20211103145122.17338-2-lczerner@redhat.com Signed-off-by: Theodore Ts'o <tytso@mit.edu> |

ext4: implement support for get/set fs label
Implement support for FS_IOC_GETFSLABEL and FS_IOC_SETFSLABEL ioctls for online reading and setting of file system label. ext4_ioctl_getlabel() is simple, just get the label from the primary superblock. This might not be the first sb on the file system if 'sb=' mount option is used. In ext4_ioctl_setlabel() we update what ext4 currently views as a primary superblock and then proceed to update backup superblocks. There are two caveats: - the primary superblock might not be the first superblock and so it might not be the one used by userspace tools if read directly off the disk. - because the primary superblock might not be the first superblock we potentialy have to update it as part of backup superblock update. However the first sb location is a bit more complicated than the rest so we have to account for that. The superblock modification is created generic enough so the infrastructure can be used for other potential superblock modification operations, such as chaning UUID. Tested with generic/492 with various configurations. I also checked the behavior with 'sb=' mount options, including very large file systems with and without sparse_super/sparse_super2.

ext4: don't use kfree() on rcu protected pointer sbi->s_qf_names
During ext4 mount api rework the commit e6e268cb6822 ("ext4: move quota
configuration out of handle_mount_opt()") introduced a bug where we
would kfree(sbi->s_qf_names[i]) before assigning the new quota name in
ext4_apply_quota_options().
This is wrong because we're using kfree() on rcu prointer that could be
simultaneously accessed from ext4_show_quota_options() during remount.
Fix it by using rcu_replace_pointer() to replace the old qname with the
new one and then kfree_rcu() the old quota name.
Also use get_qf_name() instead of sbi->s_qf_names in strcmp() to silence
the sparse warning.

ext4: avoid trim error on fs with small groups
A user reported FITRIM ioctl failing for him on ext4 on some devices
without apparent reason. After some debugging we've found out that
these devices (being LVM volumes) report rather large discard
granularity of 42MB and the filesystem had 1k blocksize and thus group
size of 8MB. Because ext4 FITRIM implementation puts discard
granularity into minlen, ext4_trim_fs() declared the trim request as
invalid. However just silently doing nothing seems to be a more
appropriate reaction to such combination of parameters since user did
not specify anything wrong.

ext4: fix an use-after-free issue about data=journal writeback mode
Our syzkaller report an use-after-free issue that accessing the freed
buffer_head on the writeback page in __ext4_journalled_writepage(). The
problem is that if there was a truncate racing with the data=journalled
writeback procedure, the writeback length could become zero and
bget_one() refuse to get buffer_head's refcount, then the truncate
procedure release buffer once we drop page lock, finally, the last
ext4_walk_page_buffers() trigger the use-after-free problem.
sync truncate
ext4_sync_file()
file_write_and_wait_range()
ext4_setattr(0)
inode->i_size = 0
ext4_writepage()
len = 0
__ext4_journalled_writepage()
page_bufs = page_buffers(page)
ext4_walk_page_buffers(bget_one) <- does not get refcount

free_buffer_head()
ext4_walk_page_buffers(page_bufs) <- trigger use-after-free
After commit bdf96838aea6 ("ext4: fix race between truncate and
__ext4_journalled_writepage()"), we have already handled the racing
case, so the bget_one() and bput_one() are not needed. So this patch
simply remove these hunk, and recheck the i_size to make it safe.
