2023-04-11tools/nolibc/stdio: Implement vprintf()Mark Brown
vprintf() is equivalent to vfprintf() to stdout so implement it as a simple wrapper for the existing vfprintf(), allowing us to build kselftest.h.

2023-04-06ACPICA: actbl2: Replace 1-element arrays with flexible arraysKees Cook
ACPICA commit 44f1af0664599e87bebc3a1260692baa27b2f264 Similar to "Replace one-element array with flexible-array", replace the 1-element array with a proper flexible array member as defined by C99. This allows the code to operate without tripping compile-time and run- time bounds checkers (e.g. via __builtin_object_size(), -fsanitize=bounds, and/or -fstrict-flex-arrays=3). The sizeof() uses with struct acpi_nfit_flush_address and struct acpi_nfit_smbios have been adjusted to drop the open-coded subtraction of the trailing single element. The result is no binary differences in .text nor .data sections.

When deleting the netns and recreating a new one while re-adding the veth interface, there is a small window of time during which the old veth interface has not yet been removed.

2023-04-05maple_tree: fix write memory barrier of nodes once dead for RCU modeLiam R. Howlett
During the development of the maple tree, the strategy of freeing multiple nodes changed and, in the process, the pivots were reused to store pointers to dead nodes. To ensure the readers see accurate pivots, the writers need to mark the nodes as dead and call smp_wmb() to ensure any readers can identify the node as dead before using the pivot values. There were two places where the old method of marking the node as dead without smp_wmb() were being used, which resulted in RCU readers seeing the wrong pivot value before seeing the node was dead. Fix this race condition by using mte_set_node_dead() which has the smp_wmb() call to ensure the race is closed. Add a WARN_ON() to the ma_free_rcu() call to ensure all nodes being freed are marked as dead to ensure there are no other call paths besides the two updated paths. This is necessary for the RCU mode of the maple tree.

2023-03-30test/vsock: new skbuff appending testArseniy Krasnov
This adds test which checks case when data of newly received skbuff is appended to the last skbuff in the socket's queue. It looks like simple test with 'send()' and 'recv()', but internally it triggers logic which appends one received skbuff to another. Test checks that this feature works correctly. This test is actual only for virtio transport.

2023-03-29Merge branch 'slab/for-6.4/slob-removal' into slab/for-nextVlastimil Babka
A series by myself to remove CONFIG_SLOB: The SLOB allocator was deprecated in 6.2 and there have been no complaints so far so let's proceed with the removal. Besides the code cleanup, the main immediate benefit will be allowing kfree() family of function to work on kmem_cache_alloc() objects, which was incompatible with SLOB. This includes kfree_rcu() which had no kmem_cache_free_rcu() counterpart yet and now it shouldn't be necessary anymore. Otherwise it's all straightforward removal. After this series, 'git grep slob' or 'git grep SLOB' will have 3 remaining relevant hits in non-mm code: - tomoyo - patch submitted and carried there, doesn't need to wait for this series - skbuff - patch to cleanup now-unnecessary #ifdefs will be posted to netdev after this is merged, as requested to avoid conflicts - ftrace ring_buffer - patch to remove obsolete comment is carried there The rest of 'git grep SLOB' hits are false positives, or intentional (CREDITS, and mm/Kconfig SLUB_TINY description to help those that will happen to migrate later).

2023-03-28selftests: prctl: Add new prctl test for PR_SET_VMA actionIvan Orlov
This patch will add the new test, which covers the prctl call with PR_SET_VMA command. The test tries to give a name to the anonymous VMA within the process memory map, and then checks the result of the operation by parsing 'maps' virtual file. Additionally, the test tries to call the prctl PR_SET_VMA command with invalid arguments, and checks the error codes for correctness. At the moment anonymous VMA naming through prctl call functionality is not covered with any tests, so I think implementing it makes sense. In version 2 of this patch I consider the selftest Makefile rule about TARGETS entries order - I moved the 'prctl' entry in the Makefile to follow the lexicographic order. In version 1 it was placed at the end of the list. Signed-off-by: Ivan Orlov <ivan.orlov0322@gmail.com> Signed-off-by: Shuah Khan <skhan@linuxfoundation.org>

2023-03-27tools/nolibc: add support for stack protectorThomas Weißschuh
This is useful when using nolibc for security-critical tools. Using nolibc has the advantage that the code is easily auditable and sandboxable with seccomp as no unexpected syscalls are used. Using compiler-assistent stack protection provides another security mechanism. For this to work the compiler and libc have to collaborate. This patch adds the following parts to nolibc that are required by the compiler: * __stack_chk_guard: random sentinel value * __stack_chk_fail: handler for detected stack smashes In addition an initialization function is added that randomizes the sentinel value. Only support for global guards is implemented. Register guards are useful in multi-threaded context which nolibc does not provide support for.

2023-03-27pm-graph: Update to v5.11Todd Brandt
install_latest_from_github.sh: - Added a new script which allows users to install the latest pm-graph from the upstream github repo. This is useful if the kernel source version has issues that have already been fixed in github. sleepgraph.py: - Updated all the dmesg suspend/resume PM print formats to be able to process recent timelines using dmesg only. - Added ethtool output to the log for the system's ethernet device id the ethtool exists. This helps in debugging network issues. - Made the tool more robustly handle events where mangled dmesg or ftrace outputs do not include all the requisite data. The tool fails gracefully instead of creating a garbled timeline. Signed-off-by: Todd Brandt <todd.e.brandt@intel.com> [ rjw: Changelog edits ] Signed-off-by: Rafael J.
