Matthieu Baerts says: ==================== mptcp: fixes for 6.3 Patch 1 fixes a possible deadlock in subflow_error_report() reported by lockdep. The report was in fact a false positive but the modification makes sense and silences lockdep to allow syzkaller to find real issues. The regression has been introduced in v5.12. Patch 2 is a refactoring needed to be able to fix the two next issues. It improves the situation and can be backported up to v6.0. Patches 3 and 4 fix UaF reported by KASAN. It fixes issues potentially visible since v5.7 and v5.19 but only reproducible until recently (v6.0). These two patches depend on patch 2/7. Patch 5 fixes the order of the printed values: expected vs seen values. The regression has been introduced recently: v6.3-rc1. Patch 6 adds missing ro_after_init flags. A previous patch added them for other functions but these two have been missed. This previous patch has been backported to stable versions (up to v5.12) so probably better to do the same here. Patch 7 fixes tcp_set_state() being called twice in a row since v5.10. Patch 8 fixes another lockdep false positive issue but this time in MPTCP PM code. Same here, some modifications in the code has been made to silence this issue and help finding real ones later. This issue can be seen since v6.2. v1: https://lore.kernel.org/r/20230227-upstream-net-20230227-mptcp-fixes-v1-0-070e30ae4a8e@tessares.net ==================== Link: https://lore.kernel.org/r/20230227-upstream-net-20230227-mptcp-fixes-v2-0-47c2e95eada9@tessares.net Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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 Restructured Text 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.
