cifs: nosharesock should not share socket with future sessions
Today, when a new mount is done with nosharesock, we ensure that we don't select an existing matching session. However, we don't mark the connection as nosharesock, which means that those could be shared with future sessions. Fixed it with this commit. Also printing this info in DebugData.

mm, thp: fix incorrect unmap behavior for private pages
When truncating pagecache on file THP, the private pages of a process
should not be unmapped mapping. This incorrect behavior on a dynamic
shared libraries which will cause related processes to happen core dump.
A simple test for a DSO (Prerequisite is the DSO mapped in file THP):
int main(int argc, char *argv[])
{
int fd;
fd = open(argv[1], O_WRONLY);
if (fd < 0) {
perror("open");
}
close(fd);
return 0;
}
The test only to open a target DSO, and do nothing. But this operation
will lead one or more process to happen core dump. This patch mainly to
fix this bug.

mm, thp: lock filemap when truncating page cache
Patch series "fix two bugs for file THP".
This patch (of 2):
Transparent huge page has supported read-only non-shmem files. The
file- backed THP is collapsed by khugepaged and truncated when written
(for shared libraries).
However, there is a race when multiple writers truncate the same page
cache concurrently.
In that case, subpage(s) of file THP can be revealed by find_get_entry
in truncate_inode_pages_range, which will trigger PageTail BUG_ON in
truncate_inode_page, as follows:

mm/smaps: simplify shmem handling of pte holes
Firstly, check_shmem_swap variable is actually not necessary, because it's always set with pte_hole hook; checking each would work. Meanwhile, the check within smaps_pte_entry is not easy to follow. E.g., pte_none() check is not needed as "!pte_present && !is_swap_pte" is the same. Since at it, use the pte_hole() helper rather than dup the page cache lookup. Still keep the CONFIG_SHMEM part so the code can be optimized to nop for !SHMEM. There will be a very slight functional change in smaps_pte_entry(), that for !SHMEM we'll return early for pte_none (before checking page==NULL), but that's even nicer.

Simplify it as a step towards a clean W=1 build. As all architectures
define cmpxchg() as a statement expression these days, it is no longer
necessary to evaluate its return code, and the if() can just be droped.

cifs: Create a new shared file holding smb2 pdu definitions
This file will contain all the definitions we need for SMB2 packets and will follow the naming convention of MS-SMB2.PDF as closely as possible to make it easier to cross-reference beween the definitions and the standard. The content of this file will mostly consist of migration of existing definitions in the cifs/smb2.pdu.h and ksmbd/smb2pdu.h files with some additional tweaks as the two files have diverged. This patch introduces the new smbfs_common/smb2pdu.h file and migrates the SMB2 header as well as TREE_CONNECT and TREE_DISCONNECT to the shared file.

Merge branch 'per_signal_struct_coredumps-for-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
Pull per signal_struct coredumps from Eric Biederman: "Current coredumps are mixed up with the exit code, the signal handling code, and the ptrace code making coredumps much more complicated than necessary and difficult to follow. This series of changes starts with ptrace_stop and cleans it up, making it easier to follow what is happening in ptrace_stop. Then cleans up the exec interactions with coredumps. Then cleans up the coredump interactions with exit. Finally the coredump interactions with the signal handling code is cleaned up. The first and last changes are bug fixes for minor bugs. I believe the fact that vfork followed by execve can kill the process the called vfork if exec fails is sufficient justification to change the userspace visible behavior. In previous discussions some of these changes were organized differently and individually appeared to make the code base worse. As currently written I believe they all stand on their own as cleanups and bug fixes. Which means that even if the worst should happen and the last change needs to be reverted for some unimaginable reason, the code base will still be improved. If the worst does not happen there are a more cleanups that can be made. Signals that generate coredumps can easily become eligible for short circuit delivery in complete_signal. The entire rendezvous for generating a coredump can move into get_signal. The function force_sig_info_to_task be written in a way that does not modify the signal handling state of the target task (because coredumps are eligible for short circuit delivery). Many of these future cleanups can be done another way but nothing so cleanly as if coredumps become per signal_struct" * 'per_signal_struct_coredumps-for-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: coredump: Limit coredumps to a single thread group coredump: Don't perform any cleanups before dumping core exit: Factor coredump_exit_mm out of exit_mm exec: Check for a pending fatal signal instead of core_state ptrace: Remove the unnecessary arguments from arch_ptrace_stop signal: Remove the bogus sigkill_pending in ptrace_stop |

New code for 5.16:
* Bug fixes and cleanups for kernel memory allocation usage, this time
without touching the mm code.
* Refactor the log recovery mechanism that preserves held resources
across a transaction roll so that it uses the exact same mechanism
that we use for that during regular runtime.
* Fix bugs and tighten checking around btree heights.
* Remove more old typedefs.
* Fix perag reference leaks when racing with growfs.
* Remove unused fields from xfs_btree_cur.
* Allocate various scrub structures on the heap to reduce stack usage.
* Pack xfs_btree_cur fields and rearrange to support arbitrary heights.
* Compute maximum possible heights for each btree height, and use that
to set up slab caches for each btree type.
* Finally remove kmem_zone_t, since these have always been struct
kmem_cache on Linux.
* Compact the structures used to coordinate work intent items.
* Set up slab caches for each work intent item type.
* Rename the "bmap_add_free" function to "free_extent_later", which

* Fix corruption warning on unmount when a CoW preallocation covers a
data fork delalloc reservation but then the CoW fails.

Pull xfs updates from Darrick Wong:
"This cycle we've worked on fixing bugs and improving XFS' memory
footprint.
The most notable fixes include: fixing a corruption warning (and free
space accounting skew) if copy on write fails; fixing slab cache
misuse if SLOB is enabled, which apparently was broken for years
without anybody noticing; and fixing a potential race with online
shrinkfs.
Otherwise, the bulk of the changes here involve setting up separate
slab caches for frequently used items such as btree cursors and log
intent items, and compacting the structures to reduce memory usage of
those items substantially. This also sets us up to support larger
btrees in future kernels. We also switch parts of online fsck to
allocate scrub context information from the heap instead of using
stack space.
Summary:
- Bug fixes and cleanups for kernel memory allocation usage, this
time without touching the mm code.
- Refactor the log recovery mechanism that preserves held resources
across a transaction roll so that it uses the exact same mechanism
that we use for that during regular runtime.

gfs2: Fix mmap + page fault deadlocks
Functions gfs2_file_read_iter and gfs2_file_write_iter are both
accessing the user buffer to write to or read from while holding the
inode glock. In the most basic scenario, that buffer will not be
resident and it will be mapped to the same file. Accessing the buffer
will trigger a page fault, and gfs2 will deadlock trying to take the
same inode glock again while trying to handle that fault.
Fix that and similar, more complex scenarios by disabling page faults
while accessing user buffers. To make this work, introduce a small
amount of new infrastructure and fix some bugs that didn't trigger so
far, with page faults enabled.

cifs: add mount parameter tcpnodelay
Although corking and uncorking the socket (which cifs.ko already does) should usually have the desired benefit, using the new tcpnodelay mount option causes tcp_sock_set_nodelay() to be set on the socket which may be useful in order to ensure that we don't ever have cases where the network stack is waiting on sending an SMB request until multiple SMB requests have been added to the send queue (since this could lead to long latencies). To enable it simply append "tcpnodelay" it to the mount options Reviewed-by: Paulo Alcantara (SUSE) <pc@cjr.nz> Signed-off-by: Steve French <stfrench@microsoft.com> |

cifs: To match file servers, make sure the server hostname matches
We generally rely on a bunch of factors to differentiate between servers. For example, IP address, port etc. For certain server types (like Azure), it is important to make sure that the server hostname matches too, even if the both hostnames currently resolve to the same IP address.

afs: Set mtime from the client for yfs create operations
For operations that create vnodes on the server such as CreateFile, MakeDir or Symlink, the server will store its own current time as the mtime if the client doesn't pass in a time in the accompanying StoreStatus structure. If the server and client clocks are not well synchronized, the client may see timestamps in the future or inconsistent dependency checks with "make" for files that are not modified after creation: make[2]: Warning: File 'arch/x86/kernel/apic/modules.order' has modification time 0.14 s in the future make[2]: warning: Clock skew detected. Your build may be incomplete. This is already handled correctly for non yfs operations; also set the mtime for the corresponding yfs operations.

Pull selinux updates from Paul Moore:
- Add LSM/SELinux/Smack controls and auditing for io-uring.
As usual, the individual commit descriptions have more detail, but we
were basically missing two things which we're adding here:
+ establishment of a proper audit context so that auditing of
io-uring ops works similarly to how it does for syscalls (with
some io-uring additions because io-uring ops are *not* syscalls)
+ additional LSM hooks to enable access control points for some of
the more unusual io-uring features, e.g. credential overrides.
The additional audit callouts and LSM hooks were done in conjunction
with the io-uring folks, based on conversations and RFC patches
earlier in the year.
- Fixup the binder credential handling so that the proper credentials
are used in the LSM hooks; the commit description and the code
comment which is removed in these patches are helpful to understand
the background and why this is the proper fix.
- Enable SELinux genfscon policy support for securityfs, allowing
improved SELinux filesystem labeling for other subsystems which make
use of securityfs, e.g. IMA.

There's been pressure to allow non root to tracefs in a controlled fashion, and using groups is probably the safest. - Bootconfig memory managament updates. - Bootconfig clean up to have the tools directory be less dependent on changes in the kernel tree. - Allow perf to be traced by function tracer. - Rewrite of function graph tracer to be a callback from the function tracer instead of having its own trampoline (this change will happen on an arch by arch basis, and currently only x86_64 implements it). - Allow multiple direct trampolines (bpf hooks to functions) be batched together in one synchronization. - Allow histogram triggers to add variables that can perform calculations against the event's fields. - Use the linker to determine architecture callbacks from the ftrace trampoline to allow for proper parameter prototypes and prevent warnings from the compiler. - Extend histogram triggers to key off of variables. - Have trace recursion use bit magic to determine preempt context over if branches. - Have trace recursion disable preemption as all use cases do anyway. - Added testing for verification of tracing utilities. - Various small clean ups and fixes. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCYYBdxhQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qp1sAQD2oYFwaG3sx872gj/myBcHIBSKdiki Hry5csd8zYDBpgD+Poylopt5JIbeDuoYw/BedgEXmscZ8Qr7VzjAXdnv/Q4= =Loz8 -----END PGP SIGNATURE----- Merge tag 'trace-v5.16' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace Pull tracing updates from Steven Rostedt: - kprobes: Restructured stack unwinder to show properly on x86 when a stack dump happens from a kretprobe callback. - Fix to bootconfig parsing - Have tracefs allow owner and group permissions by default (only denying others).

overflow updates for v5.16-rc1
The end goal of the current buffer overflow detection work[0] is to gain full compile-time and run-time coverage of all detectable buffer overflows seen via array indexing or memcpy(), memmove(), and memset(). The str*() family of functions already have full coverage. While much of the work for these changes have been on-going for many releases (i.e. 0-element and 1-element array replacements, as well as avoiding false positives and fixing discovered overflows[1]), this series contains the foundational elements of several related buffer overflow detection improvements by providing new common helpers and FORTIFY_SOURCE changes needed to gain the introspection required for compiler visibility into array sizes. Also included are a handful of already Acked instances using the helpers (or related clean-ups), with many more waiting at the ready to be taken via subsystem-specific trees[2]. The new helpers are: - struct_group() for gaining struct member range introspection. - memset_after() and memset_startat() for clearing to the end of structures. - DECLARE_FLEX_ARRAY() for using flex arrays in unions or alone in structs. Also included is the beginning of the refactoring of FORTIFY_SOURCE to support memcpy() introspection, fix missing and regressed coverage under GCC, and to prepare to fix the currently broken Clang support. Finishing this work is part of the larger series[0], but depends on all the false positives and buffer overflow bug fixes to have landed already and those that depend on this series to land. As part of the FORTIFY_SOURCE refactoring, a set of both a compile-time and run-time tests are added for FORTIFY_SOURCE and the mem*()-family functions respectively. The compile time tests have found a legitimate (though corner-case) bug[6] already. Please note that the appearance of "panic" and "BUG" in the FORTIFY_SOURCE refactoring are the result of relocating existing code, and no new use of those code-paths are expected nor desired. Finally, there are two tree-wide conversions for 0-element arrays and flexible array unions to gain sane compiler introspection coverage that result in no known object code differences. After this series (and the changes that have now landed via netdev and usb), we are very close to finally being able to build with -Warray-bounds and -Wzero-length-bounds. However, due corner cases in GCC[3] and Clang[4], I have not included the last two patches that turn on these options, as I don't want to introduce any known warnings to the build. Hopefully these can be solved soon.

Scheduler updates:
- Revert the printk format based wchan() symbol resolution as it can leak
the raw value in case that the symbol is not resolvable.
- Make wchan() more robust and work with all kind of unwinders by
enforcing that the task stays blocked while unwinding is in progress.
- Prevent sched_fork() from accessing an invalid sched_task_group
- Improve asymmetric packing logic
- Extend scheduler statistics to RT and DL scheduling classes and add
statistics for bandwith burst to the SCHED_FAIR class.
- Properly account SCHED_IDLE entities
- Prevent a potential deadlock when initial priority is assigned to a
newly created kthread. A recent change to plug a race between cpuset and
__sched_setscheduler() introduced a new lock dependency which is now
triggered. Break the lock dependency chain by moving the priority
assignment to the thread function.
- Fix the idle time reporting in /proc/uptime for NOHZ enabled systems.
- Improve idle balancing in general and especially for NOHZ enabled
systems.
- Provide proper interfaces for live patching so it does not have to
fiddle with scheduler internals.
- Add cluster aware scheduling support.
- A small set of tweaks for RT (irqwork, wait_task_inactive(), various
scheduler options and delaying mmdrop)
- The usual small tweaks and improvements all over the place

Pull btrfs updates from David Sterba:
"The updates this time are more under the hood and enhancing existing
features (subpage with compression and zoned namespaces).
Performance related:
- misc small inode logging improvements (+3% throughput, -11% latency
on sample dbench workload)
- more efficient directory logging: bulk item insertion, less tree
searches and locking
- speed up bulk insertion of items into a b-tree, which is used when
logging directories, when running delayed items for directories
(fsync and transaction commits) and when running the slow path
(full sync) of an fsync (bulk creation run time -4%, deletion -12%)
Core:
- continued subpage support
- make defragmentation work
- make compression write work
- zoned mode
- support ZNS (zoned namespaces), zone capacity is number of
usable blocks in each zone
- add dedicated block group (zoned) for relocation, to prevent
out of order writes in some cases
- greedy block group reclaim, pick the ones with least usable
space first
- preparatory work for send protocol updates
- error handling improvements
- cleanups and refactoring
Fixes:
- lockdep warnings
- in show_devname callback, on seeding device
- device delete on loop device due to conversions to workqueues
- fix deadlock between chunk allocation and chunk btree modifications
- fix tracking of missing device count and status"

Firstly, EROFS LZMA algorithm support, specifically called MicroLZMA, is available as an option for embedded devices, LiveCDs and/or as the secondary auxiliary compression algorithm besides the primary algorithm in one file. In order to better support the LZMA fixed-sized output compression, especially for 4KiB pcluster size (which has lowest memory pressure thus useful for memory-sensitive scenarios), Lasse introduced a new LZMA header/container format called MicroLZMA to minimize the original LZMA1 header (for example, we don't need to waste 4-byte dictionary size and another 8-byte uncompressed size, which can be calculated by fs directly, for each pcluster) and enable EROFS fixed-sized output compression. Note that MicroLZMA can also be later used by other things in addition to EROFS too where wasting minimal amount of space for headers is important and it can be only compiled by enabling XZ_DEC_MICROLZMA. MicroLZMA has been supported by the latest upstream XZ embedded [1] & XZ utils [2], apply the latest related XZ embedded upstream patches by the XZ author Lasse here. Secondly, multiple device is also supported in this cycle, which is designed for multi-layer container images. By working together with inter-layer data deduplication and compression, we can achieve the next high-performance container image solution. Our team will announce the new Nydus container image service [3] implementation with new RAFS v6 (EROFS-compatible) format in Open Source Summit 2021 China [4] soon. Besides, the secondary compression head support and readmore decompression strategy are also included in this cycle. There are also some minor bugfixes and cleanups, as always.
