- objpool: Fix choosing allocation for percpu slots Fixes to allocate objpool's percpu slots correctly according to the GFP flag. It checks whether "any bit" in GFP_ATOMIC is set to choose the vmalloc source, but it should check "all bits" in GFP_ATOMIC flag is set, because GFP_ATOMIC is a combined flag. - tracing/probes: Fix MAX_TRACE_ARGS limit handling If more than MAX_TRACE_ARGS are passed for creating a probe event, the entries over MAX_TRACE_ARG in trace_arg array are not initialized. Thus if the kernel accesses those entries, it crashes. This rejects creating event if the number of arguments is over MAX_TRACE_ARGS. - tracing: Consider the NULL character when validating the event length A strlen() is used when parsing the event name, and the original code does not consider the terminal null byte. Thus it can pass the name 1 byte longer than the buffer. This fixes to check it correctly. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEh7BulGwFlgAOi5DV2/sHvwUrPxsFAmcZBJ0ACgkQ2/sHvwUr Pxu4qAgAm+mIiCaBGyolsT1oB5EF+9gztbwRtcAOY1811RJZ0XiQPuOwtZfijpBr 1Pl+SjubRKhLg+lLHEuCQHxkqlTSp+zrjkF+A0hFlB38nJ5P3pIw+b5pM5FCvhY+ w0tBTwkjiRBS9h1z88c74ciKYA/XR4apcMMUrPQZUCHq8P73Wu/Fo2lhnCVGBs6q nYESyrTcOCDR0c6HP9D2GWxQFtbbCyAfotUjX37EIooTcl7ufAr8IPm8jBx7EzCa WM841FwbuIgGbFCGYlG1/lOR+Qf7FszKAY5SBJMV/BiyFbxJqZfA5DWfJcrZ9YpW pl86oKWyEkidwx8OIiB3Y1enPzUUJQ== =8oUB -----END PGP SIGNATURE----- Merge tag 'probes-fixes-v6.12-rc4.2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull probes fixes from Masami Hiramatsu: - objpool: Fix choosing allocation for percpu slots Fixes to allocate objpool's percpu slots correctly according to the GFP flag.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
