[PATCH 6.6.y] netfilter: nf_tables: use timestamp to check for set element timeout

by jianqi.ren.cn＠windriver.com

From: Pablo Neira Ayuso <pablo(a)netfilter.org> [ Upstream commit 7395dfacfff65e9938ac0889dafa1ab01e987d15 ] Add a timestamp field at the beginning of the transaction, store it in the nftables per-netns area. Update set backend .insert, .deactivate and sync gc path to use the timestamp, this avoids that an element expires while control plane transaction is still unfinished. .lookup and .update, which are used from packet path, still use the current time to check if the element has expired. And .get path and dump also since this runs lockless under rcu read size lock. Then, there is async gc which also needs to check the current time since it runs asynchronously from a workqueue.

[PATCH] string: Disable read_word_at_a_time() optimizations if kernel MTE is enabled

by Peter Collingbourne

The optimized strscpy() and dentry_string_cmp() routines will read 8 unaligned bytes at a time via the function read_word_at_a_time(), but this is incompatible with MTE which will fault on a partially invalid read. The attributes on read_word_at_a_time() that disable KASAN are invisible to the CPU so they have no effect on MTE. Let's fix the bug for now by disabling the optimizations if the kernel is built with HW tag-based KASAN and consider improvements for followup changes.

[PATCH v5 0/5] samsung: pinctrl: Add support for eint_fltcon_offset and filter selection on gs101

by Peter Griffin

Hi folks, This series fixes support for correctly saving and restoring fltcon0 and fltcon1 registers on gs101 for non-alive banks where the fltcon register offset is not at a fixed offset (unlike previous SoCs). This is done by adding a eint_fltcon_offset and providing GS101 specific pin macros that take an additional parameter (similar to how exynosautov920 handles it's eint_con_offset). Additionally the SoC specific suspend and resume callbacks are re-factored so that each SoC variant has it's own callback containing the peculiarities for that SoC. Finally support for filter selection on alive banks is added, this is currently only enabled for gs101.
