git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab Pull slab updates from Vlastimil Babka: - SLAB deprecation: Following the discussion at LSF/MM 2023 [1] and no objections, the SLAB allocator is deprecated by renaming the config option (to make its users notice) to CONFIG_SLAB_DEPRECATED with updated help text. SLUB should be used instead. Existing defconfigs with CONFIG_SLAB are also updated. - SLAB_NO_MERGE kmem_cache flag (Jesper Dangaard Brouer): There are (very limited) cases where kmem_cache merging is undesirable, and existing ways to prevent it are hacky. Introduce a new flag to do that cleanly and convert the existing hacky users. Btrfs plans to use this for debug kernel builds (that use case is always fine), networking for performance reasons (that should be very rare). - Replace the usage of weak PRNGs (David Keisar Schmidt): In addition to using stronger RNGs for the security related features, the code is a bit cleaner. - Misc code cleanups (SeongJae Parki, Xiongwei Song, Zhen Lei, and zhaoxinchao) Link: https://lwn.net/Articles/932201/ [1] * tag 'slab-for-6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/vbabka/slab: mm/slab_common: use SLAB_NO_MERGE instead of negative refcount mm/slab: break up RCU readers on SLAB_TYPESAFE_BY_RCU example code mm/slab: add a missing semicolon on SLAB_TYPESAFE_BY_RCU example code mm/slab_common: reduce an if statement in create_cache() mm/slab: introduce kmem_cache flag SLAB_NO_MERGE mm/slab: rename CONFIG_SLAB to CONFIG_SLAB_DEPRECATED mm/slab: remove HAVE_HARDENED_USERCOPY_ALLOCATOR mm/slab_common: Replace invocation of weak PRNG mm/slab: Replace invocation of weak PRNG slub: Don't read nr_slabs and total_objects directly slub: Remove slabs_node() function slub: Remove CONFIG_SMP defined check slub: Put objects_show() into CONFIG_SLUB_DEBUG enabled block slub: Correct the error code when slab_kset is NULL mm/slab: correct return values in comment for _kmem_cache_create()

2023-05-26mm/slab: rename CONFIG_SLAB to CONFIG_SLAB_DEPRECATEDVlastimil Babka12-12/+0
As discussed at LSF/MM [1] [2] and with no objections raised there, deprecate the SLAB allocator. Rename the user-visible option so that users with CONFIG_SLAB=y get a new prompt with explanation during make oldconfig, while make olddefconfig will just switch to SLUB. In all defconfigs with CONFIG_SLAB=y remove the line so those also switch to SLUB. Regressions due to the switch should be reported to linux-mm and slab maintainers.

2022-01-22mm: remove cleancacheChristoph Hellwig12-12/+0
Patch series "remove Xen tmem leftovers". Since the removal of the Xen tmem driver in 2019, the cleancache hooks are entirely unused, as are large parts of frontswap. This series against linux-next (with the folio changes included) removes cleancaches, and cuts down frontswap to the bits actually used by zswap. This patch (of 13): The cleancache subsystem is unused since the removal of Xen tmem driver in commit 814bbf49dcd0 ("xen: remove tmem driver").

2021-06-10m68k/q40: Replace q40ide driver with pata_falcon and falconideFinn Thain2-2/+1
This allows m68k q40 systems to switch from the deprecated IDE subsystem to libata. Enhance the byte-swapping falconide and pata_falcon platform drivers to accept an irq resource, for use on q40. Atari ST-DMA IRQ arrangements seem to co-exist with q40 IRQ arrangements without too much mess. The new IO resources were added solely for the purpose of making request_region() reservations identical to those made by q40ide: these regions aren't used for actual IO.

2021-06-10m68k/mac: Replace macide driver with generic platform driversFinn Thain2-2/+0
This allows m68k mac systems to switch from the deprecated IDE subsystem to libata. This was tested on my Quadra 630. I haven't tested it on my PowerBook 150 because I don't have a RAM adapter board for it. It appears that the hardware I tested doesn't need macide_clear_irq() or macide_test_irq(). If it did, the generic driver would not have worked. It's possible that those routines are needed for the PowerBook 150 but we can cross that bridge if and when we come to it. BTW, macide_clear_irq() appears to suffer from a race condition. The write to the interrupt flags register could have unintended side effects as it may alter other flag bits. Fortunately, all of the other bits are unused by Linux. When tested on my Quadra 630, the assignment *ide_ifr &= ~0x20 was observed to have no effect on bit 5, so it may be redundant anyway.

2021-05-07drivers/char: remove /dev/kmem for goodDavid Hildenbrand1-1/+0
Patch series "drivers/char: remove /dev/kmem for good". Exploring /dev/kmem and /dev/mem in the context of memory hot(un)plug and memory ballooning, I started questioning the existence of /dev/kmem. Comparing it with the /proc/kcore implementation, it does not seem to be able to deal with things like a) Pages unmapped from the direct mapping (e.g., to be used by secretmem) -> kern_addr_valid(). virt_addr_valid() is not sufficient. b) Special cases like gart aperture memory that is not to be touched -> mem_pfn_is_ram() Unless I am missing something, it's at least broken in some cases and might fault/crash the machine. Looks like its existence has been questioned before in 2005 and 2010 [1], after ~11 additional years, it might make sense to revive the discussion. CONFIG_DEVKMEM is only enabled in a single defconfig (on purpose or by mistake?). All distributions disable it: in Ubuntu it has been disabled for more than 10 years, in Debian since 2.6.31, in Fedora at least starting with FC3, in RHEL starting with RHEL4, in SUSE starting from 15sp2, and OpenSUSE has it disabled as well. 1) /dev/kmem was popular for rootkits [2] before it got disabled basically everywhere. Ubuntu documents [3] "There is no modern user of /dev/kmem any more beyond attackers using it to load kernel rootkits.". RHEL documents in a BZ [5] "it served no practical purpose other than to serve as a potential security problem or to enable binary module drivers to access structures/functions they shouldn't be touching" 2) /proc/kcore is a decent interface to have a controlled way to read kernel memory for debugging puposes. (will need some extensions to deal with memory offlining/unplug, memory ballooning, and poisoned pages, though) 3) It might be useful for corner case debugging [1]. KDB/KGDB might be a better fit, especially, to write random memory; harder to shoot yourself into the foot. 4) "Kernel Memory Editor" [4] hasn't seen any updates since 2000 and seems to be incompatible with 64bit [1]. For educational purposes, /proc/kcore might be used to monitor value updates -- or older kernels can be used. 5) It's broken on arm64, and therefore, completely disabled there. Looks like it's essentially unused and has been replaced by better suited interfaces for individual tasks (/proc/kcore, KDB/KGDB). Let's just remove it.

The logic behind the quirks is always built into the sr driver. This also removes the config from all the defconfig files that are enabling this already.

What we saw in the review discussion was that if we go a step farther than my patch and mess with uapi headers there are pieces of code that won't compile, but nothing minds the system call actually disappearing from the kernel" Link: https://lore.kernel.org/lkml/201910011140.EA0181F13@keescook/ * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: sysctl: Remove the sysctl system call
2019-11-26sysctl: Remove the sysctl system callEric W. Biederman1-1/+0
This system call has been deprecated almost since it was introduced, and in a survey of the linux distributions I can no longer find any of them that enable CONFIG_SYSCTL_SYSCALL. The only indication that I can find that anyone might care is that a few of the defconfigs in the kernel enable CONFIG_SYSCTL_SYSCALL. However this appears in only 31 of 414 defconfigs in the kernel, so I suspect this symbols presence is simply because it is harmless to include rather than because it is necessary. As there appear to be no users of the sysctl system call, remove the code. As this removes one of the few uses of the internal kernel mount of proc I hope this allows for even more simplifications of the proc filesystem.
