| * | | | mm: generalize SYS_SUPPORTS_HUGETLBFS (rename as ARCH_SUPPORTS_HUGETLBFS)Anshuman Khandual2021-05-051-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SYS_SUPPORTS_HUGETLBFS config has duplicate definitions on platforms that subscribe it. Instead, just make it a generic option which can be selected on applicable platforms. Also rename it as ARCH_SUPPORTS_HUGETLBFS instead. This reduces code duplication and makes it cleaner.

Briefly, Landlock provides for unprivileged application sandboxing. From Mickaël's cover letter: "The goal of Landlock is to enable to restrict ambient rights (e.g. global filesystem access) for a set of processes. Because Landlock is a stackable LSM [1], it makes possible to create safe security sandboxes as new security layers in addition to the existing system-wide access-controls. This kind of sandbox is expected to help mitigate the security impact of bugs or unexpected/malicious behaviors in user-space applications. Landlock empowers any process, including unprivileged ones, to securely restrict themselves. Landlock is inspired by seccomp-bpf but instead of filtering syscalls and their raw arguments, a Landlock rule can restrict the use of kernel objects like file hierarchies, according to the kernel semantic. Landlock also takes inspiration from other OS sandbox mechanisms: XNU Sandbox, FreeBSD Capsicum or OpenBSD Pledge/Unveil. In this current form, Landlock misses some access-control features. This enables to minimize this patch series and ease review. This series still addresses multiple use cases, especially with the combined use of seccomp-bpf: applications with built-in sandboxing, init systems, security sandbox tools and security-oriented APIs [2]" The cover letter and v34 posting is here: https://lore.kernel.org/linux-security-module/20210422154123.13086-1-mic@digikod.net/ See also: https://landlock.io/ This code has had extensive design discussion and review over several years" Link: https://lore.kernel.org/lkml/50db058a-7dde-441b-a7f9-f6837fe8b69f@schaufler-ca.com/ [1] Link: https://lore.kernel.org/lkml/f646e1c7-33cf-333f-070c-0a40ad0468cd@digikod.net/ [2] * tag 'landlock_v34' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: landlock: Enable user space to infer supported features landlock: Add user and kernel documentation samples/landlock: Add a sandbox manager example selftests/landlock: Add user space tests landlock: Add syscall implementations arch: Wire up Landlock syscalls fs,security: Add sb_delete hook landlock: Support filesystem access-control LSM: Infrastructure management of the superblock landlock: Add ptrace restrictions landlock: Set up the security framework and manage credentials landlock: Add ruleset and domain management landlock: Add object management

In an attempt to avoid the need for additional firmware changes every time a new function is added, introduce a UID to identify the service provider as being compatible with KVM. Once this has been established, additional services can be discovered via a feature bitmap.

The kernel virtual mapping layer grew support for mapping memory with > PAGE_SIZE ptes with commit 0ddab1d2ed66 ("lib/ioremap.c: add huge I/O map capability interfaces"), and implemented support for using those huge page mappings with ioremap. According to the submission, the use-case is mapping very large non-volatile memory devices, which could be GB or TB: https://lore.kernel.org/lkml/1425404664-19675-1-git-send-email-toshi.kani@hp.com/ The benefit is said to be in the overhead of maintaining the mapping, perhaps both in memory overhead and setup / teardown time. Memory overhead for the mapping with a 4kB page and 8 byte page table is 2GB per TB of mapping, down to 4MB / TB with 2MB pages. The same huge page vmap infrastructure can be quite easily adapted and used for mapping vmalloc memory pages without more complexity for arch or core vmap code. However unlike ioremap, vmalloc page table overhead is not a real problem, so the advantage to justify this is performance. Several of the most structures in the kernel (e.g., vfs and network hash tables) are allocated with vmalloc on NUMA machines, in order to distribute access bandwidth over the machine. Mapping these with larger pages can improve TLB usage significantly, for example this reduces TLB misses by nearly 30x on a `git diff` workload on a 2-node POWER9 (59,800 -> 2,100) and reduces CPU cycles by 0.54%, due to vfs hashes being allocated with 2MB pages. [ Other numbers? - The difference is even larger in a guest due to more costly TLB misses. - Eric Dumazet was keen on the network hash performance possibilities. - Other archs? Ding was doing x86 testing. ] The kernel module allocator also uses vmalloc to map module images even on non-NUMA, which can result in high iTLB pressure on highly modular distro type of kernels. This series does not implement huge mappings for modules yet, but it's a step along the way. Rick Edgecombe was looking at that IIRC. The per-cpu allocator similarly might be able to take advantage of this. Also on the todo list. The disadvantages of this I can see are: * Memory fragmentation can waste some physical memory because it will attempt to allocate larger pages to fit the required size, rounding up (once the requested size is >= 2MB). - I don't see it being a big problem in practice unless some user crops up that allocates thousands of 2.5MB ranges. We can tewak heuristics a bit there if needed to reduce peak waste. * Less granular mappings can make the NUMA distribution less balanced. - Similar to the above. - Could also allocate all major system hashes with one allocation up-front and spread them all across the one block, which should help overall NUMA distribution and reduce fragmentation waste. * Callers might expect something about the underlying allocated pages. - Tried to keep the apperance of base PAGE_SIZE pages throughout the APIs and exposed data structures. - Added a VM_NO_HUGE_VMAP flag to hammer troublesome cases with. - Finally, added a nohugevmalloc boot option to turn it off (independent of nohugeiomap). This patch (of 14): ARM uses its own PMD folding scheme which is missing pud_page which should just pass through to pmd_page. Move this from the 3-level page table to common header.

Hence enabling CONFIG_MEMTEST and providing a valid memtest=[1..N] kernel command line option might not trigger the memory pattern tests as would be expected in normal circumstances. This situation is misleading. The change here prevents the above mentioned problem after introducing a new config option ARCH_USE_MEMTEST that should be subscribed on platforms that call early_memtest(), in order to enable the config CONFIG_MEMTEST. Conversely CONFIG_MEMTEST cannot be enabled on platforms where it would not be tested anyway.

After the commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e rx/tx delay config"), the delays are working correctly, however, "rgmii" means no delay and the phy doesn't work. So need to set the phy-mode to "rgmii-id" to show that RX/TX delays are enabled.

Lately, support to fetch the MAC address by an NVMEM provider was added. But this will only work with platform devices. It will not work with PCI devices (e.g. of an integrated root complex) and esp. not with DSA ports. There is an of_* variant of the nvmem binding which works without devices. The returned data of a nvmem_cell_read() has to be freed after use. On the other hand the return of_get_mac_address() points to some static data without a lifetime. The trick for now, was to allocate a device resource managed buffer which is then returned. This will only work if we have an actual device. Change it, so that the caller of of_get_mac_address() has to supply a buffer where the MAC address is written to. Unfortunately, this will touch all drivers which use the of_get_mac_address(). Usually the code looks like: const char *addr; addr = of_get_mac_address(np); if (!IS_ERR(addr)) ether_addr_copy(ndev->dev_addr, addr); This can then be simply rewritten as: of_get_mac_address(np, ndev->dev_addr); Sometimes is_valid_ether_addr() is used to test the MAC address. of_get_mac_address() already makes sure, it just returns a valid MAC address. Thus we can just test its return code. But we have to be careful if there are still other sources for the MAC address before the of_get_mac_address(). In this case we have to keep the is_valid_ether_addr() call. The following coccinelle patch was used to convert common cases to the new style. Afterwards, I've manually gone over the drivers and fixed the return code variable: either used a new one or if one was already available use that. Mansour Moufid, thanks for that coccinelle patch! <spml> @a@ identifier x; expression y, z; @@ - x = of_get_mac_address(y); + x = of_get_mac_address(y, z); <... - ether_addr_copy(z, x); ...> @@ identifier a.x; @@ - if (<+... x ...+>) {} @@ identifier a.x; @@ if (<+... x ...+>) { ... } - else {} @@ identifier a.x; expression e; @@ - if (<+... x ...+>@e) - {} - else + if (!(e)) {...} @@ expression x, y, z; @@ - x = of_get_mac_address(y, z); + of_get_mac_address(y, z); ... when != x </spml> All drivers, except drivers/net/ethernet/aeroflex/greth.c, were compile-time tested.

The spear is not using this chipselect or PL022 for anything and should be using device tree like the rest of the platform so just delete the offending platform data.

Apple M1 and Nuvoton WPCM450 have separate branches because they are new SoC families that require changes outside of device tree files. The other four are variations of already supported chips and get merged through this branch: - STMicroelectronics STM32H750 is one of many variants of STM32 microcontrollers based on the Cortex-M7 core. This is particularly notable since we rarely add support for new MMU-less chips these days. In this case, the board that gets added along with the platform is not a SoC reference platform but the "Art Pi" (https://art-pi.gitee.io/website/) machine that was originally design for the RT-Thread RTOS. - NXP i.MX8QuadMax is a variant of the growing i.MX8 embedded/industrial SoC family, using two Cortex-A72 and four Cortex-A53 cores. It gets added along with its reference board, the "NXP i.MX8QuadMax Multisensory Enablement Kit". - Qualcomm SC7280 is a Laptop SoC following the SC7180 (Snapdragon 7c) that is used in some Chromebooks and Windows laptops. Only a reference board is added for the moment. - TI AM64x Sita4ra is a new version of the K3 SoC family for industrial control, motor control, remote IO, IoT gateway etc., similar to the older AM65x family. Two reference machines are added alongside. Among the newly added machines, there is a very clear skew towards 64-bit machines now, with 12 32-bit machines compared to 23 64-bit machines.
