kbuild: deb-pkg: add KDEB_SOURCE_COMPRESS to specify source compression
Add KDEB_SOURCE_COMPRESS to specify the compression for the orig and debian tarballs. (cf. the existing KDEB_COMPRESS is used to specify the compression for binary packages.) Supported algorithms are gzip, bzip2, lzma, and xz, all of which are supported by dpkg-source. The current default is gzip. You can change it via the environment variable, for example, 'KDEB_SOURCE_COMPRESS=xz make deb-pkg'.

selftests/bpf: avoid mark_all_scalars_precise() trigger in one of iter tests
iter_pass_iter_ptr_to_subprog subtest is relying on actual array size
being passed as subprog parameter. This combined with recent fixes to
precision tracking in conditional jumps ([0]) is now causing verifier to
backtrack all the way to the point where sum() and fill() subprogs are
called, at which point precision backtrack bails out and forces all the
states to have precise SCALAR registers. This in turn causes each
possible value of i within fill() and sum() subprogs to cause
a different non-equivalent state, preventing iterator code to converge.
For now, change the test to assume fixed size of passed in array. Once
BPF verifier supports precision tracking across subprogram calls, these
changes will be reverted as unnecessary.

Merge tag 'nf-next-23-04-22' of git://git.kernel.org/pub/scm/linux/kernel/git/netfilter/nf-next
Pablo Neira Ayuso says:
====================
Netfilter/IPVS updates for net-next
1) Reduce jumpstack footprint: Stash chain in last rule marker in blob for
tracing. Remove last rule and chain from jumpstack. From Florian Westphal.
2) nf_tables validates all tables before committing the new rules.
Unfortunately, this has two drawbacks:
- Since addition of the transaction mutex pernet state gets written to
outside of the locked section from the cleanup callback, this is
wrong so do this cleanup directly after table has passed all checks.
- Revalidate tables that saw no changes. This can be avoided by
keeping the validation state per table, not per netns.
From Florian Westphal.
3) Get rid of a few redundant pointers in the traceinfo structure.
The three removed pointers are used in the expression evaluation loop,
so gcc keeps them in registers. Passing them to the (inlined) helpers
thus doesn't increase nft_do_chain text size, while stack is reduced
by another 24 bytes on 64bit arches. From Florian Westphal.
4) IPVS cleanups in several ways without implementing any functional
changes, aside from removing some debugging output:
- Update width of source for ip_vs_sync_conn_options
The operation is safe, use an annotation to describe it properly.
- Consistently use array_size() in ip_vs_conn_init()
It seems better to use helpers consistently.
- Remove {Enter,Leave}Function. These seem to be well past their
use-by date.
- Correct spelling in comments.
From Simon Horman.
5) Extended netlink error report for netdevice in flowtables and
netdev/chains. Allow for incrementally add/delete devices to netdev
basechain. Allow to create netdev chain without device.

Qualcomm Clock updates for v6.4
New drivers for Global clock controller on SM7150, IPQ9574, MSM8917 and IPQ5332 are added. New GPU clock controllers for SM6115, SM6125, SM6375 and SA8775P are added. The APSS IPQ PLL driver is refactored to support different PLL types, support for the Stromer Plus PLL type is added, and support for IPQ5332 is introduced. Helpers for settings sleep, wake and retain bits of CBCR registers are introduced and used in some of the newly introduced GPU clock drivers. platform_driver remove callbacks is transitioned to remove_new, as part of the system wide cleanup effort. In the Display clock controller for QCM2290, the MDSS_CORE reset is introduced and the non-existent DSI1PHY clock is removed. IPQ4019 Global clock controller is transitioned to parent_data. USB GDSCs in SM6375, MSM8996 and MSM8998 are changed to use retention as disabled state, to avoid collapsing them during suspend. The CX GDSC in the SM6375 GPU clock controller has it's disable-wait value corrected. QCM2290 SDCC2 src clock moves to floor_ops. The two EMAC GDSCs are added for SC8280XP. Relevant RCGs in the SM6115 Global clock controller are moved to use shared_ops. PCIe PIPE clock operations on SM8350 are updated, to ensure the mux is parked when the parent PLL is disabled. GDSCs are added to the SC7280 LPASS audio clock controller. The RPM clock controller is transitioned to use the managed version of of_clk_add_hw_provider(). Missing XO clocks are added to MSM8226 and MSM8974. DeviceTree bindings are added for the various newly supported clock controllers, the binding for KPSS ACC and GCC drivers are converted to YAML and a few fixes are introduced. -----BEGIN PGP SIGNATURE----- iQJJBAABCAAzFiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmRGlZ0VHGFuZGVyc3Nv bkBrZXJuZWwub3JnAAoJEAsfOT8Nma3Fe5QP+wWJBk9bAHmo0Alh7egu0fhpWyP8 XjiG3WQC17fGlkxbGAaZjP4iyaPWozLjleJYArMKAsjLGr5ZH01Qycaxz50/8Cgt RNDTnw6G2UqjB2R4U6TfP9NazdwSiqKDONVxOzI/WN5UlXjHXUlTES014KXoz6cN at2k6YY95KP/qz06SFOijMGZkJolysX08C9QKaFlTSpY5JunlNoVMztkuCcj3Lrp D9xrsaniSKuGIIEZZ84TLuou38TeACvAmu/dgJqXjor+DUNd6eZHaiWd3HnMz/wk Vks5BIz+ojjAPqG8U7Xkj/A5lgIcOfUDQyRC7ntvE9zWMyqW80lWVPX51iusFRQN cxmozNHApsXqkpyVGnfxfUdwjgJ/XPrlYhHMrfvVP5SxhXVfYSs0WzS0ppxY3gI5 CMhnXTBsutssOJPXnioO2JMuFFTekJ4GQ0KpLS7yhuc5CwpuUMpoVqDpI0+TnHaL LROrfGtxNO0UXfIuclQ8Eq6z2DUeYzwkEyPe0kDX5VnenUIIIssJKmlmOUfszJP+ AbxyfACbIgfW7eXP5oR+8CxIVft7b0bn6SvjkFNKyVQAYBKqCwuvBqOR+yDgoVWF vTkvjQbCYiSj14PWyCzoo5Lk3P5lf+uCRl/UXdLGrtzAEVfq8hWiNQ2qWg6m1lbT eZPS3qgKQNL9VapP =b1g6 -----END PGP SIGNATURE----- Merge tag 'qcom-clk-for-6.4' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into clk-qcom Pull Qualcomm clk driver updates from Bjorn Andersson: New drivers for Global clock controller on SM7150, IPQ9574, MSM8917 and IPQ5332 are added.

Pull erofs updates from Gao Xiang:
"In this cycle, sub-page block support for uncompressed files is
available. It's mainly used to enable original signing ('golden')
4k-block images on arm64 with 16/64k pages. In addition, end users
could also use this feature to build a manifest to directly refer to
golden tar data.
Besides, long xattr name prefix support is also introduced in this
cycle to avoid too many xattrs with the same prefix (e.g. overlayfs
xattrs). It's useful for erofs + overlayfs combination (like Composefs
model): the image size is reduced by ~14% and runtime performance is
also slightly improved.
Others are random fixes and cleanups as usual.

- Add sub-page block size support for uncompressed files
- Support flattened block device for multi-blob images to be attached

bpf: Add __rcu_read_{lock,unlock} into btf id deny list
The tracing recursion prevention mechanism must be protected by rcu, that
leaves __rcu_read_{lock,unlock} unprotected by this mechanism. If we trace
them, the recursion will happen. Let's add them into the btf id deny list.
When CONFIG_PREEMPT_RCU is enabled, it can be reproduced with a simple bpf
program as such:
SEC("fentry/__rcu_read_lock")
int fentry_run()
{
return 0;

bpf: Disable bpf_refcount_acquire kfunc calls until race conditions are fixed
As reported by Kumar in [0], the shared ownership implementation for BPF programs has some race conditions which need to be addressed before it can safely be used. This patch does so in a minimal way instead of ripping out shared ownership entirely, as proper fixes for the issues raised will follow ASAP, at which point this patch's commit can be reverted to re-enable shared ownership. The patch removes the ability to call bpf_refcount_acquire_impl from BPF programs. Programs can only bump refcount and obtain a new owning reference using this kfunc, so removing the ability to call it effectively disables shared ownership. Instead of changing success / failure expectations for bpf_refcount-related selftests, this patch just disables them from running for now.

Pull acl updates from Christian Brauner:
"After finishing the introduction of the new posix acl api last cycle
the generic POSIX ACL xattr handlers are still around in the
filesystems xattr handlers for two reasons:
(1) Because a few filesystems rely on the ->list() method of the
generic POSIX ACL xattr handlers in their ->listxattr() inode
operation.
(2) POSIX ACLs are only available if IOP_XATTR is raised. The
IOP_XATTR flag is raised in inode_init_always() based on whether
the sb->s_xattr pointer is non-NULL. IOW, the registered xattr
handlers of the filesystem are used to raise IOP_XATTR. Removing
the generic POSIX ACL xattr handlers from all filesystems would
risk regressing filesystems that only implement POSIX ACL support
and no other xattrs (nfs3 comes to mind).
This contains the work to decouple POSIX ACLs from the IOP_XATTR flag
as they don't depend on xattr handlers anymore. So it's now possible
to remove the generic POSIX ACL xattr handlers from the sb->s_xattr
list of all filesystems. This is a crucial step as the generic POSIX
ACL xattr handlers aren't used for POSIX ACLs anymore and POSIX ACLs
don't depend on the xattr infrastructure anymore.
Adressing problem (1) will require more long-term work. It would be
best to get rid of the ->list() method of xattr handlers completely at
some point.
For erofs, ext{2,4}, f2fs, jffs2, ocfs2, and reiserfs the nop POSIX
ACL xattr handler is kept around so they can continue to use
array-based xattr handler indexing.
This update does simplify the ->listxattr() implementation of all
these filesystems however"

The fd has been visible to userspace and might already be in use. Instead, a file descriptor should be reserved but not installed into the caller's file descriptor table.

And if all failure paths are cleared the file descriptor and file can be installed into the task's file descriptor table. This helper is now used in all places that open coded this functionality before. For example, this is currently done during copy_process() and fanotify used pidfd_create(), which returns a pidfd that has already been made visibile in the caller's file descriptor table, but then closed it using close_fd().

worker from a userspace process.
Such user workers will run with the same credentials as the userspace
process they were created from providing stronger security and
accounting guarantees than the traditional override_creds() approach
ever could've hoped for.
The original work was heavily based and optimzed for the needs of
io_uring which was the first user. However, as it quickly turned out
the ability to create user workers inherting properties from a
userspace process is generally useful.
The vhost subsystem currently creates workers using the kthread api.
The consequences of using the kthread api are that RLIMITs don't work
correctly as they are inherited from khtreadd. This leads to bugs
where more workers are created than would be allowed by the RLIMITs of
the userspace process in lieu of which workers are created.
Problems like this disappear with user workers created from the
userspace processes for which they perform the work. In addition,
providing this api allows vhost to remove additional complexity. For
example, cgroup and mm sharing will just work out of the box with user
workers based on the relevant userspace process instead of manually
ensuring the correct cgroup and mm contexts are used.
So the vhost subsystem should simply be made to use the same mechanism
as io_uring. To this end the original mechanism used for
create_io_thread() is generalized into user workers:
- Introduce PF_USER_WORKER as a generic indicator that a given task
is a user worker, i.e., a kernel task that was created from a
userspace process. Now a PF_IO_WORKER thread is just a specialized
version of PF_USER_WORKER. So io_uring io workers raise both flags.
- Make copy_process() available to core kernel code
- Extend struct kernel_clone_args with the following bitfields
allowing to indicate to copy_process():
- to create a user worker (raise PF_USER_WORKER)
- to not inherit any files from the userspace process
- to ignore signals
After all generic changes are in place the vhost subsystem implements
a new dedicated vhost api based on user workers. Finally, vhost is
switched to rely on the new api moving it off of kthreads.
Thanks to Mike for sticking it out and making it through this rather
arduous journey"

Commit volume in documentation is relatively low this time, but there is
still a fair amount going on, including:
- Reorganizing the architecture-specific documentation under
Documentation/arch. This makes the structure match the source directory
and helps to clean up the mess that is the top-level Documentation
directory a bit. This work creates the new directory and moves x86 and
most of the less-active architectures there. The current plan is to move
the rest of the architectures in 6.5, with the patches going through the
appropriate subsystem trees.
- Some more Spanish translations and maintenance of the Italian
translation.
- A new "Kernel contribution maturity model" document from Ted.
- A new tutorial on quickly building a trimmed kernel from Thorsten.
Plus the usual set of updates and fixes.

Pull RCU updates from Joel Fernandes:
- Updates and additions to MAINTAINERS files, with Boqun being added to
the RCU entry and Zqiang being added as an RCU reviewer.
I have also transitioned from reviewer to maintainer; however, Paul
will be taking over sending RCU pull-requests for the next merge
window.
- Resolution of hotplug warning in nohz code, achieved by fixing
cpu_is_hotpluggable() through interaction with the nohz subsystem.
Tick dependency modifications by Zqiang, focusing on fixing usage of
the TICK_DEP_BIT_RCU_EXP bitmask.
- Avoid needless calls to the rcu-lazy shrinker for CONFIG_RCU_LAZY=n
kernels, fixed by Zqiang.
- Improvements to rcu-tasks stall reporting by Neeraj.
- Initial renaming of k[v]free_rcu() to k[v]free_rcu_mightsleep() for
increased robustness, affecting several components like mac802154,
drbd, vmw_vmci, tracing, and more.
A report by Eric Dumazet showed that the API could be unknowingly
used in an atomic context, so we'd rather make sure they know what
they're asking for by being explicit:
https://lore.kernel.org/all/20221202052847.2623997-1-edumazet@google.com/
- Documentation updates, including corrections to spelling,
clarifications in comments, and improvements to the srcu_size_state
comments.
- Better srcu_struct cache locality for readers, by adjusting the size
of srcu_struct in support of SRCU usage by Christoph Hellwig.
- Teach lockdep to detect deadlocks between srcu_read_lock() vs
synchronize_srcu() contributed by Boqun.
Previously lockdep could not detect such deadlocks, now it can.
- Integration of rcutorture and rcu-related tools, targeted for v6.4
from Boqun's tree, featuring new SRCU deadlock scenarios, test_nmis
module parameter, and more
- Miscellaneous changes, various code cleanups and comment improvements

Two major features are included into this pull request. The links for
the landed patch sets are below. The .machine keyring, used for Machine Owner Keys (MOK), acquired the ability to store only CA enforced keys, and put rest to the .platform keyring, thus separating the code signing keys from the keys that are used to sign certificates. This essentially unlocks the use of the .machine keyring as a trust anchor for IMA. It is an opt-in feature, meaning that the additional contraints won't brick anyone who does not care about them. The 2nd feature is the enablement of interrupt based transactions with discrete TPM chips (tpm_tis). There was code for this existing but it never really worked so I consider this a new feature rather than a bug fix. Before the driver just falled back to the polling mode.

In keeping with current kernel conventions, this moves all of these comment blocks to the top of the function definitions, transforming them into the kdoc format in the process. This should make it much easier to maintain these comments, which are the main source of LSM hook documentation. For the most part the comment contents were left as-is, although some glaring errors were corrected. Expect additional edits in the future as we slowly update and correct the comment blocks. This is the bulk of the diffstat. - Introduce LSM_ORDER_LAST Similar to how LSM_ORDER_FIRST is used to specify LSMs which should be ordered before "normal" LSMs, the LSM_ORDER_LAST is used to specify LSMs which should be ordered after "normal" LSMs. This is one of the prerequisites for transitioning IMA/EVM to a proper LSM. - Remove the security_old_inode_init_security() hook The security_old_inode_init_security() LSM hook only allows for a single xattr which is problematic both for LSM stacking and the IMA/EVM-as-a-LSM effort. This finishes the conversion over to the security_inode_init_security() hook and removes the single-xattr LSM hook. - Fix a reiserfs problem with security xattrs During the security_old_inode_init_security() removal work it became clear that reiserfs wasn't handling security xattrs properly so we fixed it. * tag 'lsm-pr-20230420' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: (32 commits) reiserfs: Add security prefix to xattr name in reiserfs_security_write() security: Remove security_old_inode_init_security() ocfs2: Switch to security_inode_init_security() reiserfs: Switch to security_inode_init_security() security: Remove integrity from the LSM list in Kconfig Revert "integrity: double check iint_cache was initialized" security: Introduce LSM_ORDER_LAST and set it for the integrity LSM device_cgroup: Fix typo in devcgroup_css_alloc description lsm: fix a badly named parameter in security_get_getsecurity() lsm: fix doc warnings in the LSM hook comments lsm: styling fixes to security/security.c lsm: move the remaining LSM hook comments to security/security.c lsm: move the io_uring hook comments to security/security.c lsm: move the perf hook comments to security/security.c lsm: move the bpf hook comments to security/security.c lsm: move the audit hook comments to security/security.c lsm: move the binder hook comments to security/security.c lsm: move the sysv hook comments to security/security.c lsm: move the key hook comments to security/security.c lsm: move the xfrm hook comments to security/security.c ... |

Pull selinux updates from Paul Moore:
- Stop passing the 'selinux_state' pointers as function arguments
As discussed during the end of the last development cycle, passing a
selinux_state pointer through the SELinux code has a noticeable
impact on performance, and with the current code it is not strictly
necessary.
This simplifies things by referring directly to the single
selinux_state global variable which should help improve SELinux
performance.
- Uninline the unlikely portions of avc_has_perm_noaudit()
This change was also based on a discussion from the last development
cycle, and is heavily based on an initial proof of concept patch from
you. The core issue was that avc_has_perm_noaudit() was not able to
be inlined, as intended, due to its size. We solved this issue by
extracting the less frequently hit portions of avc_has_perm_noaudit()
into a separate function, reducing the size of avc_has_perm_noaudit()
to the point where the compiler began inlining the function. We also
took the opportunity to clean up some ugly RCU locking in the code
that became uglier with the change.
- Remove the runtime disable functionality
After several years of work by the userspace and distro folks, we are
finally in a place where we feel comfortable removing the runtime
disable functionality which we initially deprecated at the start of
2020.
There is plenty of information in the kernel's deprecation (now
removal) notice, but the main motivation was to be able to safely
mark the LSM hook structures as '__ro_after_init'.
LWN also wrote a good summary of the deprecation this morning which
offers a more detailed history:
https://lwn.net/SubscriberLink/927463/dcfa0d4ed2872f03
- Remove the checkreqprot functionality
The original checkreqprot deprecation notice stated that the removal
would happen no sooner than June 2021, which means this falls hard
into the "better late than never" bucket.
The Kconfig and deprecation notice has more detail on this setting,
but the basic idea is that we want to ensure that the SELinux policy
allows for the memory protections actually applied by the kernel, and
not those requested by the process.
While we haven't found anyone running a supported distro that is
affected by this deprecation/removal, anyone who is affected would
only need to update their policy to reflect the reality of their
applications' mapping protections.
- Minor Makefile improvements
Some minor Makefile improvements to correct some dependency issues
likely only ever seen by SELinux developers. I expect we will have at
least one more tweak to the Makefile during the next merge window,
but it didn't quite make the cutoff this time around.

perf cs-etm: Add separate decode paths for timeless and per-thread modes
Timeless and per-thread are orthogonal concepts that are currently treated as if they are the same (per-thread == timeless). This breaks when you modify the command line or itrace options to something that the current logic doesn't expect. For example: # Force timeless with Z --itrace=Zi10i # Or inconsistent record options -e cs_etm/timestamp=1/ --per-thread Adding Z for decoding in per-cpu mode is particularly bad because in per-thread mode trace channel IDs are discarded and all assumed to be 0, which would mix trace from different CPUs in per-cpu mode. Although the results might not be perfect in all scenarios, if the user requests no timestamps, it should still be possible to decode in either mode. Especially if the relative times of samples in different processes aren't interesting, quite a bit of space can be saved by turning off timestamps in per-cpu mode.

Merge branch 'x86-rep-insns': x86 user copy clarifications
Merge my x86 user copy updates branch.
This cleans up a lot of our x86 memory copy code, particularly for user
accesses. I've been pushing for microarchitectural support for good
memory copying and clearing for a long while, and it's been visible in
how the kernel has aggressively used 'rep movs' and 'rep stos' whenever
possible.
And that micro-architectural support has been improving over the years,
to the point where on modern CPU's the best option for a memory copy
that would become a function call (as opposed to being something that
can just be turned into individual 'mov' instructions) is now to inline
the string instruction sequence instead.
However, that only makes sense when we have the modern markers for this:
the x86 FSRM and FSRS capabilities ("Fast Short REP MOVS/STOS").
So this cleans up a lot of our historical code, gets rid of the legacy
marker use ("REP_GOOD" and "ERMS") from the memcpy/memset cases, and
replaces it with that modern reality. Note that REP_GOOD and ERMS end
up still being used by the known large cases (ie page copyin gand
clearing).
The reason much of this ends up being about user memory accesses is that
the normal in-kernel cases are done by the compiler (__builtin_memcpy()
and __builtin_memset()) and getting to the point where we can use our
instruction rewriting to inline those to be string instructions will
need some compiler support.
In contrast, the user accessor functions are all entirely controlled by
the kernel code, so we can change those arbitrarily.
Thanks to Borislav Petkov for feedback on the series, and Jens testing
some of this on micro-architectures I didn't personally have access to.
* x86-rep-insns:
x86: rewrite '__copy_user_nocache' function
x86: remove 'zerorest' argument from __copy_user_nocache()
x86: set FSRS automatically on AMD CPUs that have FSRM
x86: improve on the non-rep 'copy_user' function
x86: improve on the non-rep 'clear_user' function
x86: inline the 'rep movs' in user copies for the FSRM case
x86: move stac/clac from user copy routines into callers
x86: don't use REP_GOOD or ERMS for user memory clearing
x86: don't use REP_GOOD or ERMS for user memory copies
x86: don't use REP_GOOD or ERMS for small memory clearing
