Furthermore, because the balancing mode sets the MPOL_F_MORON flag, it would be displayed as 'default' due a workaround introduced a few years earlier in 8790c71a18e5 ("mm/mempolicy.c: fix mempolicy printing in numa_maps"). To tidy this up we implement two changes: Replace the MPOL_F_MORON check by pointer comparison against the preferred_node_policy array. By doing this we generalise the current special casing and replace the incorrect 'default' with the correct 'bind' for the mode. Secondly, we add a string representation and corresponding handling for the MPOL_F_NUMA_BALANCING flag. With the two changes together we start showing the balancing flag when it is set and therefore complete the fix. Representation format chosen is to separate multiple flags with vertical bars, following what existed long time ago in kernel 2.6.25. But as between then and now there wasn't a way to display multiple flags, this patch does not change the format in practice.

It is because x86_32 uses CONFIG_X86_32 instead of CONFIG_32BIT. !CONFIG_64BIT should cover all 32 bit machines.

[PATCH v9] af_packet: Handle outgoing VLAN packets without hardware offloading

by Chengen Du

The issue initially stems from libpcap. The ethertype will be overwritten as the VLAN TPID if the network interface lacks hardware VLAN offloading. In the outbound packet path, if hardware VLAN offloading is unavailable, the VLAN tag is inserted into the payload but then cleared from the sk_buff struct. Consequently, this can lead to a false negative when checking for the presence of a VLAN tag, causing the packet sniffing outcome to lack VLAN tag information (i.e., TCI-TPID). As a result, the packet capturing tool may be unable to parse packets as expected. The TCI-TPID is missing because the prb_fill_vlan_info() function does not modify the tp_vlan_tci/tp_vlan_tpid values, as the information is in the payload and not in the sk_buff struct. The skb_vlan_tag_present() function only checks vlan_all in the sk_buff struct. In cooked mode, the L2 header is stripped, preventing the packet capturing tool from determining the correct TCI-TPID value. Additionally, the protocol in SLL is incorrect, which means the packet capturing tool cannot parse the L3 header correctly.

[PATCH 1/2] soc: fsl: qbman: delete bogus device tree fixup in qbman_init_private_mem()

by Vladimir Oltean

This is effectively a revert of commit 6ea4c0fe4570 ("soc/fsl/qbman: Update device tree with reserved memory"). What that commit intended to do: Fix up the device tree that is passed to a subsequent kexec-loaded kernel, so that the reserved-memory nodes have the same base addresses as the currently running kernel. What that commit actually does: Fix up the running device tree, which has no effect whatsoever upon the device tree passed to the next kernel. I would have refrained from making this kind of non-bugfix change in stable kernels, but qbman_init_private_mem() grossly misrepresents what this function does, and for an actual upcoming bug fix, it needs to be refactored. There is no place for the bogus code afterwards, so it needs to go as part of that, sadly.

[PATCH v4] mm/numa_balancing: Teach mpol_to_str about the balancing mode

by Tvrtko Ursulin

From: Tvrtko Ursulin <tvrtko.ursulin(a)igalia.com> Since balancing mode was added in bda420b98505 ("numa balancing: migrate on fault among multiple bound nodes"), it was possible to set this mode but it wouldn't be shown in /proc/<pid>/numa_maps since there was no support for it in the mpol_to_str() helper. Furthermore, because the balancing mode sets the MPOL_F_MORON flag, it would be displayed as 'default' due a workaround introduced a few years earlier in 8790c71a18e5 ("mm/mempolicy.c: fix mempolicy printing in numa_maps"). To tidy this up we implement two changes: Replace the MPOL_F_MORON check by pointer comparison against the preferred_node_policy array. By doing this we generalise the current special casing and replace the incorrect 'default' with the correct 'bind' for the mode. Secondly, we add a string representation and corresponding handling for the MPOL_F_NUMA_BALANCING flag. With the two changes together we start showing the balancing flag when it is set and therefore complete the fix. Representation format chosen is to separate multiple flags with vertical bars, following what existed long time ago in kernel 2.6.25. But as between then and now there wasn't a way to display multiple flags, this patch does not change the format in practice. Some /proc/<pid>/numa_maps output examples: 555559580000 bind=balancing:0-1,3 file=... 555585800000 bind=balancing|static:0,2 file=... 555635240000 prefer=relative:0 file= v2: * Fully fix by introducing MPOL_F_KERNEL. v3: * Abandoned the MPOL_F_KERNEL approach in favour of pointer comparisons. * Removed lookup generalisation for easier backporting. * Replaced commas as separator with vertical bars. * Added a few more words about the string format in the commit message. v4: * Use is_power_of_2. * Use ARRAY_SIZE and update recommended buffer size for two flags.
