UPSTREAM: mm/slub: fix endianness bug for alloc/free_traces attributes
On big-endian s390, the alloc/free_traces attributes produce endless
output, because of always 0 idx in slab_debugfs_show().
idx is de-referenced from *v, which points to a loff_t value, with
unsigned int idx = *(unsigned int *)v;
This will only give the upper 32 bits on big-endian, which remain 0.
Instead of only fixing this de-reference, during discussion it seemed
more appropriate to change the seq_ops so that they use an explicit
iterator in private loc_track struct.
This patch adds idx to loc_track, which will also fix the endianness
bug.

UPSTREAM: mm, slub: fix incorrect memcg slab count for bulk free
kmem_cache_free_bulk() will call memcg_slab_free_hook() for all objects
when doing bulk free. So we shouldn't call memcg_slab_free_hook() again
for bulk free to avoid incorrect memcg slab count.

UPSTREAM: mm, slub: fix mismatch between reconstructed freelist depth and cnt
If object's reuse is delayed, it will be excluded from the reconstructed
freelist. But we forgot to adjust the cnt accordingly. So there will
be a mismatch between reconstructed freelist depth and cnt. This will
lead to free_debug_processing() complaining about freelist count or a
incorrect slub inuse count.

UPSTREAM: mm, slub: fix two bugs in slab_debug_trace_open()
Patch series "Fixups for slub". This series contains various bug fixes for slub. We fix memoryleak, use-afer-free, NULL pointer dereferencing and so on in slub. More details can be found in the respective changelogs. This patch (of 5): It's possible that __seq_open_private() will return NULL. So we should check it before using lest dereferencing NULL pointer. And in error paths, we forgot to release private buffer via seq_release_private(). Memory will leak in these paths.

UPSTREAM: mm, slub: allocate private object map for debugfs listings
Slub has a static spinlock protected bitmap for marking which objects are on freelist when it wants to list them, for situations where dynamically allocating such map can lead to recursion or locking issues, and on-stack bitmap would be too large. The handlers of debugfs files alloc_traces and free_traces also currently use this shared bitmap, but their syscall context makes it straightforward to allocate a private map before entering locked sections, so switch these processing paths to use a private bitmap.

FROMLIST: mm: slub: fix slub_debug disabling for list of slabs
Vijayanand Jitta reports: Consider the scenario where CONFIG_SLUB_DEBUG_ON is set and we would want to disable slub_debug for few slabs. Using boot parameter with slub_debug=-,slab_name syntax doesn't work as expected i.e; only disabling debugging for the specified list of slabs. Instead it disables debugging for all slabs, which is wrong. This patch fixes it by delaying the moment when the global slub_debug flags variable is updated. In case a "slub_debug=-,slab_name" has been passed, the global flags remain as initialized (depending on CONFIG_SLUB_DEBUG_ON enabled or disabled) and are not simply reset to 0.

mm/slub: actually fix freelist pointer vs redzoning
commit e41a49fadbc80b60b48d3c095d9e2ee7ef7c9a8e upstream.
It turns out that SLUB redzoning ("slub_debug=Z") checks from
s->object_size rather than from s->inuse (which is normally bumped to
make room for the freelist pointer), so a cache created with an object
size less than 24 would have the freelist pointer written beyond
s->object_size, causing the redzone to be corrupted by the freelist
pointer. This was very visible with "slub_debug=ZF":

mm/slub: fix redzoning for small allocations
commit 74c1d3e081533825f2611e46edea1fcdc0701985 upstream.
The redzone area for SLUB exists between s->object_size and s->inuse
(which is at least the word-aligned object_size). If a cache were
created with an object_size smaller than sizeof(void *), the in-object
stored freelist pointer would overwrite the redzone (e.g. with boot
param "slub_debug=ZF"):
BUG test (Tainted: G B ): Right Redzone overwritten

Store the freelist pointer out of line when object_size is smaller than
sizeof(void *) and redzoning is enabled.
Additionally remove the "smaller than sizeof(void *)" check under
CONFIG_DEBUG_VM in kmem_cache_sanity_check() as it is now redundant:
SLAB and SLOB both handle small sizes.
(Note that no caches within this size range are known to exist in the
kernel currently.)

mm/slub: clarify verification reporting
commit 8669dbab2ae56085c128894b181c2aa50f97e368 upstream. Patch series "Actually fix freelist pointer vs redzoning", v4. This fixes redzoning vs the freelist pointer (both for middle-position and very small caches). Both are "theoretical" fixes, in that I see no evidence of such small-sized caches actually be used in the kernel, but that's no reason to let the bugs continue to exist, especially since people doing local development keep tripping over it. :) This patch (of 3): Instead of repeating "Redzone" and "Poison", clarify which sides of those zones got tripped. Additionally fix column alignment in the trailer. Before: BUG test (Tainted: G B ): Redzone overwritten ... Redzone (____ptrval____): bb bb bb bb bb bb bb bb ........ Object (____ptrval____): f6 f4 a5 40 1d e8 ...@.. Redzone (____ptrval____): 1a aa .. Padding (____ptrval____): 00 00 00 00 00 00 00 00 ........

FROMGIT: mm/slub: add taint after the errors are printed
When running the kernel with panic_on_taint, the usual slub debug error messages are not being printed when object corruption happens. That's because we panic in add_taint(), which is called before printing the additional information. This is a bit unfortunate as the error messages are actually very useful, especially before a panic. Let's fix this by moving add_taint() after the errors are printed on the console.

FROMGIT: mm: slub: move sysfs slab alloc/free interfaces to debugfs
alloc_calls and free_calls implementation in sysfs have two issues, one is PAGE_SIZE limitation of sysfs and other is it does not adhere to "one value per file" rule. To overcome this issues, move the alloc_calls and free_calls implementation to debugfs. Debugfs cache will be created if SLAB_STORE_USER flag is set. Rename the alloc_calls/free_calls to alloc_traces/free_traces, to be inline with what it does.

FROMGIT: kasan, mm: integrate slab init_on_free with HW_TAGS
This change uses the previously added memory initialization feature of HW_TAGS KASAN routines for slab memory when init_on_free is enabled. With this change, memory initialization memset() is no longer called when both HW_TAGS KASAN and init_on_free are enabled. Instead, memory is initialized in KASAN runtime. For SLUB, the memory initialization memset() is moved into slab_free_hook() that currently directly follows the initialization loop. A new argument is added to slab_free_hook() that indicates whether to initialize the memory or not. To avoid discrepancies with which memory gets initialized that can be caused by future changes, both KASAN hook and initialization memset() are put together and a warning comment is added. Combining setting allocation tags with memory initialization improves HW_TAGS KASAN performance when init_on_free is enabled.

Revert "mm, slub: consider rest of partial list if acquire_slab() fails"
commit 9b1ea29bc0d7b94d420f96a0f4121403efc3dd85 upstream.
This reverts commit 8ff60eb052eeba95cfb3efe16b08c9199f8121cf.
The kernel test robot reports a huge performance regression due to the
commit, and the reason seems fairly straightforward: when there is
contention on the page list (which is what causes acquire_slab() to
fail), we do _not_ want to just loop and try again, because that will
transfer the contention to the 'n->list_lock' spinlock we hold, and
just make things even worse.
This is admittedly likely a problem only on big machines - the kernel
test robot report comes from a 96-thread dual socket Intel Xeon Gold
6252 setup, but the regression there really is quite noticeable:
-47.9% regression of stress-ng.rawpkt.ops_per_sec
and the commit that was marked as being fixed (

mm: memcontrol: fix slub memory accounting
[ Upstream commit 96403bfe50c344b587ea53894954a9d152af1c9d ]
SLUB currently account kmalloc() and kmalloc_node() allocations larger
than order-1 page per-node. But it forget to update the per-memcg
vmstats. So it can lead to inaccurate statistics of "slab_unreclaimable"
which is from memory.stat. Fix it by using mod_lruvec_page_state instead
of mod_node_page_state.

FROMGIT: kasan, mm: optimize kmalloc poisoning
For allocations from kmalloc caches, kasan_kmalloc() always follows kasan_slab_alloc(). Currenly, both of them unpoison the whole object, which is unnecessary. This patch provides separate implementations for both annotations: kasan_slab_alloc() unpoisons the whole object, and kasan_kmalloc() only poisons the redzone. For generic KASAN, the redzone start might not be aligned to KASAN_GRANULE_SIZE. Therefore, the poisoning is split in two parts: kasan_poison_last_granule() poisons the unaligned part, and then kasan_poison() poisons the rest. This patch also clarifies alignment guarantees of each of the poisoning functions and drops the unnecessary round_up() call for redzone_end. With this change, the early SLUB cache annotation needs to be changed to kasan_slab_alloc(), as kasan_kmalloc() doesn't unpoison objects now. The number of poisoned bytes for objects in this cache stays the same, as kmem_cache_node->object_size is equal to sizeof(struct kmem_cache_node).

FROMGIT: kasan: move _RET_IP_ to inline wrappers
Generic mm functions that call KASAN annotations that might report a bug pass _RET_IP_ to them as an argument. This allows KASAN to include the name of the function that called the mm function in its report's header. Now that KASAN has inline wrappers for all of its annotations, move _RET_IP_ to those wrappers to simplify annotation call sites.

FROMGIT: mm, kfence: insert KFENCE hooks for SLUB
Inserts KFENCE hooks into the SLUB allocator. To pass the originally requested size to KFENCE, add an argument 'orig_size' to slab_alloc*(). The additional argument is required to preserve the requested original size for kmalloc() allocations, which uses size classes (e.g. an allocation of 272 bytes will return an object of size 512). Therefore, kmem_cache::size does not represent the kmalloc-caller's requested size, and we must introduce the argument 'orig_size' to propagate the originally requested size to KFENCE. Without the originally requested size, we would not be able to detect out-of-bounds accesses for objects placed at the end of a KFENCE object page if that object is not equal to the kmalloc-size class it was bucketed into. When KFENCE is disabled, there is no additional overhead, since slab_alloc*() functions are __always_inline.

UPSTREAM: kasan, mm: fix conflicts with init_on_alloc/free
[ Upstream commit ce5716c618524241a3cea821e18ee1e0d16f6c70 ] A few places where SLUB accesses object's data or metadata were missed in a previous patch. This leads to false positives with hardware tag-based KASAN when bulk allocations are used with init_on_alloc/free. Fix the false-positives by resetting pointer tags during these accesses. (The kasan_reset_tag call is removed from slab_alloc_node, as it's added into maybe_wipe_obj_freeptr.)

UPSTREAM: kasan, mm: reset tags when accessing metadata
[ Upstream commit aa1ef4d7b3f67f7f17aa4aa34f5ec513c7e4db6c ] Kernel allocator code accesses metadata for slab objects, that may lie out-of-bounds of the object itself, or be accessed when an object is freed. Such accesses trigger tag faults and lead to false-positive reports with hardware tag-based KASAN. Software KASAN modes disable instrumentation for allocator code via KASAN_SANITIZE Makefile macro, and rely on kasan_enable/disable_current() annotations which are used to ignore KASAN reports. With hardware tag-based KASAN neither of those options are available, as it doesn't use compiler instrumetation, no tag faults are ignored, and MTE is disabled after the first one. Instead, reset tags when accessing metadata (currently only for SLUB).

mm, slub: consider rest of partial list if acquire_slab() fails
commit 8ff60eb052eeba95cfb3efe16b08c9199f8121cf upstream.
acquire_slab() fails if there is contention on the freelist of the page
(probably because some other CPU is concurrently freeing an object from
the page). In that case, it might make sense to look for a different page
(since there might be more remote frees to the page from other CPUs, and
we don't want contention on struct page).
However, the current code accidentally stops looking at the partial list
completely in that case. Especially on kernels without CONFIG_NUMA set,
this means that get_partial() fails and new_slab_objects() falls back to
new_slab(), allocating new pages. This could lead to an unnecessary
increase in memory fragmentation.

The panic occurred in slab_alloc_node() when checking for the page's node:
object = c->freelist;
page = c->page;
if (unlikely(!object || !node_match(page, node))) {
object = __slab_alloc(s, gfpflags, node, addr, c);
stat(s, ALLOC_SLOWPATH);
The issue is that object is not NULL while page is NULL which is odd but
may happen if the cache flush happened after loading object but before
loading page. Thus checking for the page pointer is required too.
The cache flush is done through an inter processor interrupt when a
piece of memory is off-lined. That interrupt is triggered when a memory
hot-unplug operation is initiated and offline_pages() is calling the
slub's MEM_GOING_OFFLINE callback slab_mem_going_offline_callback()
which is calling flush_cpu_slab(). If that interrupt is caught between
the reading of c->freelist and the reading of c->page, this could lead
to such a situation. That situation is expected and the later call to
this_cpu_cmpxchg_double() will detect the change to c->freelist and redo
the whole operation.

mm: memcg/slab: uncharge during kmem_cache_free_bulk()
Object cgroup charging is done for all the objects during allocation, but
during freeing, uncharging ends up happening for only one object in the
case of bulk allocation/freeing.
Fix this by having a separate call to uncharge all the objects from
kmem_cache_free_bulk() and by modifying memcg_slab_free_hook() to take
care of bulk uncharging.
