smb: prevent use-after-free due to open_cached_dir error paths
If open_cached_dir() encounters an error parsing the lease from the server, the error handling may race with receiving a lease break, resulting in open_cached_dir() freeing the cfid while the queued work is pending. Update open_cached_dir() to drop refs rather than directly freeing the cfid. Have cached_dir_lease_break(), cfids_laundromat_worker(), and invalidate_all_cached_dirs() clear has_lease immediately while still holding cfids->cfid_list_lock, and then use this to also simplify the reference counting in cfids_laundromat_worker() and invalidate_all_cached_dirs(). Fixes this KASAN splat (which manually injects an error and lease break in open_cached_dir()): ================================================================== BUG: KASAN: slab-use-after-free in smb2_cached_lease_break+0x27/0xb0 Read of size 8 at addr ffff88811cc24c10 by task kworker/3:1/65 CPU: 3 UID: 0 PID: 65 Comm: kworker/3:1 Not tainted 6.12.0-rc6-g255cf264e6e5-dirty #87 Hardware name: VMware, Inc.

smb: Don't leak cfid when reconnect races with open_cached_dir
open_cached_dir() may either race with the tcon reconnection even before
compound_send_recv() or directly trigger a reconnection via
SMB2_open_init() or SMB_query_info_init().
The reconnection process invokes invalidate_all_cached_dirs() via
cifs_mark_open_files_invalid(), which removes all cfids from the
cfids->entries list but doesn't drop a ref if has_lease isn't true. This
results in the currently-being-constructed cfid not being on the list,
but still having a refcount of 2. It leaks if returned from
open_cached_dir().
Fix this by setting cfid->has_lease when the ref is actually taken; the
cfid will not be used by other threads until it has a valid time.
Addresses these kmemleaks:

smb: client: handle max length for SMB symlinks
We can't use PATH_MAX for SMB symlinks because
(1) Windows Server will fail FSCTL_SET_REPARSE_POINT with
STATUS_IO_REPARSE_DATA_INVALID when input buffer is larger than
16K, as specified in MS-FSA 2.1.5.10.37.
(2) The client won't be able to parse large SMB responses that
includes SMB symlink path within SMB2_CREATE or SMB2_IOCTL
responses.
Fix this by defining a maximum length value (4060) for SMB symlinks
that both client and server can handle.

This client was only requesting READ caching, not READ and HANDLE caching in the LeaseState on the open requests we send for directories. To delay closing a handle (e.g. for caching directory contents) we should be requesting HANDLE as well as READ (as we already do for deferred close of files).

cifs: Recognize SFU char/block devices created by Windows NFS server on Windows Server <<2012
Windows NFS server versions on Windows Server older than 2012 release use for storing char and block devices modified SFU format, not compatible with the original SFU. Windows NFS server on Windows Server 2012 and new versions use different format (reparse points), not related to SFU-style. SFU / SUA / Interix subsystem stores the major and major numbers as pair of 64-bit integer, but Windows NFS server stores as pair of 32-bit integers. Which makes char and block devices between Windows NFS server <<2012 and Windows SFU/SUA/Interix subsytem incompatible. So improve Linux SMB client. When SFU mode is enabled (mount option -o sfu is specified) then recognize also these kind of char and block devices and its major and minor numbers, which are used by Windows Server versions older than 2012.

CIFS: New mount option for cifs.upcall namespace resolution
In the current implementation, the SMB filesystem on a mount point can trigger upcalls from the kernel to the userspace to enable certain functionalities like spnego, dns_resolution, amongst others. These upcalls usually either happen in the context of the mount or in the context of an application/user. The upcall handler for cifs, cifs.upcall already has existing code which switches the namespaces to the caller's namespace before handling the upcall. This behaviour is expected for scenarios like multiuser mounts, but might not cover all single user scenario with services such as Kubernetes, where the mount can happen from different locations such as on the host, from an app container, or a driver pod which does the mount on behalf of a different pod. This patch introduces a new mount option called upcall_target, to customise the upcall behaviour. upcall_target can take 'mount' and 'app' as possible values. This aids use cases like Kubernetes where the mount happens on behalf of the application in another container altogether. Having this new mount option allows the mount command to specify where the upcall should happen: 'mount' for resolving the upcall to the host namespace, and 'app' for resolving the upcall to the ns of the calling thread. This will enable both the scenarios where the Kerberos credentials can be found on the application namespace or the host namespace to which just the mount operation is "delegated".

mm: fix NULL pointer dereference in alloc_pages_bulk_noprof
We triggered a NULL pointer dereference for ac.preferred_zoneref->zone in alloc_pages_bulk_noprof() when the task is migrated between cpusets. When cpuset is enabled, in prepare_alloc_pages(), ac->nodemask may be ¤t->mems_allowed. when first_zones_zonelist() is called to find preferred_zoneref, the ac->nodemask may be modified concurrently if the task is migrated between different cpusets. Assuming we have 2 NUMA Node, when traversing Node1 in ac->zonelist, the nodemask is 2, and when traversing Node2 in ac->zonelist, the nodemask is 1. As a result, the ac->preferred_zoneref points to NULL zone. In alloc_pages_bulk_noprof(), for_each_zone_zonelist_nodemask() finds a allowable zone and calls zonelist_node_idx(ac.preferred_zoneref), leading to NULL pointer dereference. __alloc_pages_noprof() fixes this issue by checking NULL pointer in commit |

fs/proc/task_mmu: prevent integer overflow in pagemap_scan_get_args()
The "arg->vec_len" variable is a u64 that comes from the user at the start
of the function. The "arg->vec_len * sizeof(struct page_region))"
multiplication can lead to integer wrapping. Use size_mul() to avoid
that.
Also the size_add/mul() functions work on unsigned long so for 32bit
systems we need to ensure that "arg->vec_len" fits in an unsigned long.

sched/task_stack: fix object_is_on_stack() for KASAN tagged pointers
When CONFIG_KASAN_SW_TAGS and CONFIG_KASAN_STACK are enabled, the object_is_on_stack() function may produce incorrect results due to the presence of tags in the obj pointer, while the stack pointer does not have tags. This discrepancy can lead to incorrect stack object detection and subsequently trigger warnings if CONFIG_DEBUG_OBJECTS is also enabled.

crash, powerpc: default to CRASH_DUMP=n on PPC_BOOK3S_32
Fixes boot failures on 6.9 on PPC_BOOK3S_32 machines using Open Firmware.
On these machines, the kernel refuses to boot from non-zero
PHYSICAL_START, which occurs when CRASH_DUMP is on.
Since most PPC_BOOK3S_32 machines boot via Open Firmware, it should
default to off for them. Users booting via some other mechanism can still
turn it on explicitly.
Does not change the default on any other architectures for the
time being.

mm/mremap: fix address wraparound in move_page_tables()
On 32-bit platforms, it is possible for the expression `len + old_addr <
old_end` to be false-positive if `len + old_addr` wraps around.
`old_addr` is the cursor in the old range up to which page table entries
have been moved; so if the operation succeeded, `old_addr` is the *end* of
the old region, and adding `len` to it can wrap.
The overflow causes mremap() to mistakenly believe that PTEs have been
copied; the consequence is that mremap() bails out, but doesn't move the
PTEs back before the new VMA is unmapped, causing anonymous pages in the
region to be lost. So basically if userspace tries to mremap() a
private-anon region and hits this bug, mremap() will return an error and
the private-anon region's contents appear to have been zeroed.
The idea of this check is that `old_end - len` is the original start
address, and writing the check that way also makes it easier to read; so
fix the check by rearranging the comparison accordingly.
(An alternate fix would be to refactor this function by introducing an
"orig_old_start" variable or such.)
Tested in a VM with a 32-bit X86 kernel; without the patch:

mm, swap: fix allocation and scanning race with swapoff
There are two flags used to synchronize allocation and scanning with swapoff: SWP_WRITEOK and SWP_SCANNING. SWP_WRITEOK: Swapoff will first unset this flag, at this point any further swap allocation or scanning on this device should just abort so no more new entries will be referencing this device. Swapoff will then unuse all existing swap entries. SWP_SCANNING: This flag is set when device is being scanned. Swapoff will wait for all scanner to stop before the final release of the swap device structures to avoid UAF. Note this flag is the highest used bit of si->flags so it could be added up arithmetically, if there are multiple scanner. commit |

sched_ext: ops.cpu_acquire() should be called with SCX_KF_REST
ops.cpu_acquire() is currently called with 0 kf_maks which is interpreted as
SCX_KF_UNLOCKED which allows all unlocked kfuncs, but ops.cpu_acquire() is
called from balance_one() under the rq lock and should only be allowed call
kfuncs that are safe under the rq lock. Update it to use SCX_KF_REST.

bcachefs fixes for 6.12
- Assorted tiny syzbot fixes
- Shutdown path fix: "bch2_btree_write_buffer_flush_going_ro()"
The shutdown path wasn't flushing the btree write buffer, leading to
shutting down while we still had operations in flight. This fixes a
whole slew of syzbot bugs, and undoubtedly other strange heisenbugs.

tracing/ring-buffer: Clear all memory mapped CPU ring buffers on first recording
The events of a memory mapped ring buffer from the previous boot should
not be mixed in with events from the current boot. There's meta data that
is used to handle KASLR so that function names can be shown properly.
Also, since the timestamps of the previous boot have no meaning to the
timestamps of the current boot, having them intermingled in a buffer can
also cause confusion because there could possibly be events in the future.
When a trace is activated the meta data is reset so that the pointers of
are now processed for the new address space. The trace buffers are reset
when tracing starts for the first time. The problem here is that the reset
only happens on online CPUs. If a CPU is offline, it does not get reset.
To demonstrate the issue, a previous boot had tracing enabled in the boot
mapped ring buffer on reboot. On the following boot, tracing has not been
started yet so the function trace from the previous boot is still visible.
# trace-cmd show -B boot_mapped -c 3 | tail

<idle>-0 [003] d.h2. 156.462398: clear_local_APIC <-disable_local_APIC

<idle>-0 [003] d.h2. 156.462575: lmce_supported <-mce_intel_feature_clear
Now, if CPU 3 is taken offline, and tracing is started on the memory
mapped ring buffer, the events from the previous boot in the CPU 3 ring
buffer is not reset. Now those events are using the meta data from the
current boot and produces just hex values.
# echo 0 > /sys/devices/system/cpu/cpu3/online

# trace-cmd show -B boot_mapped -c 3 | tail

Reset all CPUs when starting a boot mapped ring buffer for the first time,
and not just the online CPUs.
