blk-cgroup: save IRQ state in blkg_tryget_closest()
bio_set_dev() associates the bio with a blkg through bio_associate_blkg(). If the blkg lookup misses, blkg_tryget_closest() takes q->queue_lock with spin_lock_irq() and releases it with spin_unlock_irq(), which unconditionally enables local interrupts. Callers may call bio_set_dev() with interrupts already disabled, e.g. dm-thin's pool_map() does so while holding pool->lock taken with spin_lock_irq(). The nested spin_unlock_irq() then enables interrupts while pool->lock is still held, so an I/O completion softirq can run on the same CPU, re-acquire pool->lock (thin_endio(), or overwrite_endio() -> complete_mapping_preparation()) and deadlock. lockdep reports this as inconsistent SOFTIRQ-ON-W to IN-SOFTIRQ-W usage.

sunvdc: unmap LDC cookies when the descriptor send fails
__send_request() maps the request's pages into the LDC channel's map table (ldc_map_sg()), fills in the descriptor and marks it VIO_DESC_READY before ringing the doorbell via __vdc_tx_trigger(). When the trigger fails, the error path only prints a message: the descriptor stays READY and the cookies are never unmapped. The mapping is normally released in vdc_end_one() when the peer completes the descriptor - but a descriptor whose doorbell was never sent will never complete, and since dr->prod is not advanced on failure, the reset path (vdc_requeue_inflight(), which walks [cons, prod)) never visits it either. The map table entries are leaked permanently. Since commit |

selftests: ublk: install test_common.sh and trace/ scripts
Every ublk test script sources test_common.sh from its own directory:
. "$(cd "$(dirname "$0")" && pwd)"/test_common.sh
and test_generic_02/12 additionally run bpftrace against the scripts in
trace/. Neither test_common.sh nor trace/ is listed in TEST_FILES, so
"make install" does not copy them into the install directory and every
ublk test fails when run from there:
./test_generic_02.sh: line 4: .../kselftest_install/ublk/test_common.sh: No such file or directory
./test_generic_02.sh: line 8: _have_program: command not found
The bpftrace tests are affected even when bpftrace is installed: the
missing trace/*.bt makes bpftrace exit immediately, and the tests then
report a skip rather than a failure, which hides the problem.
Add both to TEST_FILES, matching how other selftests ship their sourced
helpers (see kexec/kexec_common_lib.sh and zram/zram_lib.sh).

nvme-tcp.h: drop kernel-doc comments, fix a few descriptions
Expand @fei into @feil and @feih because the field was split due to it not being 32-bit aligned. Struct member @hdr was described twice in struct nvme_tcp_rsp_pdu, so drop one of them. These structs are defined in a spec outside of the kernel, so kernel-doc comments for them aren't needed here as well.

nvme-fc: fix double free of fabrics options when nvme_add_ctrl() fails
nvmf_create_ctrl() owns the fabrics options and frees them whenever ->create_ctrl() returns an error, so a transport must not free them on its own error paths. nvme-fc tracks this by testing ctrl->ctrl.opts in nvme_fc_ctrl_free(), which requires nvme_fc_init_ctrl() to clear that pointer on every error exit.

nvmet: reject namespace enable without device path
A newly allocated namespace has a NULL device_path until userspace configures the device_path attribute. If buffered_io is enabled before device_path is configured, nvmet_bdev_ns_enable() returns -ENOTBLK and nvmet_ns_enable() falls back to nvmet_file_ns_enable(). The latter passes the NULL device_path to filp_open(), causing a NULL pointer dereference in getname_kernel(). Reject namespace enable when device_path has not been configured.

nvmet-auth: Synchronize timeout work during SQ teardown
nvmet_auth_sq_free() cancels auth_expired_work with
cancel_delayed_work(). If the work has already started, cancellation does
not wait for the callback. Transport teardown can consequently free or
reuse the queue containing struct nvmet_sq while
nvmet_auth_expired_work() still accesses that SQ.
Add a teardown-specific helper that synchronously drains the delayed work
before freeing authentication state, and use it from nvmet_sq_destroy().
Keep the non-synchronous helper for in-band authentication state cleanup,
where the SQ owner remains alive.

nvmet-tcp: reject unsolicited H2CData PDUs
nvmet_tcp_handle_h2c_data_pdu() accepts an H2CData PDU after only checking
that its TTAG is a valid in-range command index and that the command's
data buffers are mapped. It never checks that the target has actually
solicited that data by sending an R2T for the command.
A remote host can abuse this. It submits a write command that takes the
R2T path and, before the target transmits the R2T, sends an H2CData PDU
for that command's tag. The data completes the command early, and when
the command then fails synchronously (e.g. a length mismatch caught by
nvmet_check_transfer_len()), it is completed a second time. Each
completion calls nvmet_tcp_queue_response(), so the same command is added
to queue->resp_list twice while it is still linked; the second llist_add()
makes the node point to itself (lentry->next == lentry).
nvmet_tcp_process_resp_list() then walks that self-referential node and
adds the command to resp_send_list twice. With CONFIG_DEBUG_LIST this
trips the "list_add double add" check (kernel BUG); without it the loop
never terminates and the nvmet_tcp workqueue wedges (soft-lockup). It is
remotely triggerable and needs no authentication on an allow_any_host
subsystem.
Track whether an R2T has been transmitted for a command and reject an
H2CData PDU that arrives before it. The flag is cleared on command reuse
(nvmet_tcp_get_cmd() zeroes cmd->flags) and stays set across the multiple
H2CData PDUs of a single solicited transfer.

nvme-tcp: defer TLS inline send to io_work
blk_mq holds set->srcu while queuing and running requests. The kTLS
software send path takes ctx->tx_lock. lockdep knows that tx_lock
nests under elevator_lock which then waits on srcu, so an inline
send from that path under TLS triggers circular locking.
Skip the inline send optimization for TLS queues so the send runs
from the workqueue instead. The same workqueue already retries TLS
sends on write-space notifications. Plain TCP keeps the inline path.

nvmet-tcp: fix out-of-bounds write when receiving an over-long PDU
nvmet_tcp_try_recv_pdu() reads a PDU header into the fixed 128-byte
queue->pdu union, then computes the remaining payload length as
queue->left = hdr->hlen - queue->offset + hdgst;
and reads that many more bytes into &queue->pdu + queue->offset, without
ever bounding the result against sizeof(queue->pdu).
A struct nvme_tcp_icreq_pdu is itself 128 bytes, exactly the size of the
union. Once a header digest has been negotiated (hdgst = 4), a second
ICReq passes the hlen == nvmet_tcp_pdu_size() check but yields
queue->left = 128 - 8 + 4 = 124, so bytes 8..132 are written into the
128-byte buffer -- 4 bytes past its end, over queue->hdr_digest and
queue->data_digest. Those bytes are attacker-controlled (an ICReq
carries no digest), and the duplicate ICReq is only rejected later,
after the overflow. A remote unauthenticated host can thus corrupt
kernel memory adjacent to the receive buffer.
Reject any PDU whose declared length would read past the end of
queue->pdu before the second recv.

nvmet: print namespace IDs as unsigned 32bit value
struct nvmet_ns.nsid is a u32, but a few messages print it with %d. An NSID larger than 0x7fffffff is rendered as a negative number, which is misleading in general and particularly so for the configfs messages that echo back the NSID the user just asked for. For example: [ T200] nvmet: adding nsid -16 to subsystem mysubsystem Print them with %u. The invalid-NSID error in nvmet_ns_make() keeps its %#x because the two values it rejects, 0 and NVME_NSID_ALL, are more readable in hex format.

nvme: print namespace IDs as unsigned 32bit value
NSIDs are 32-bit unsigned values, but a number of log messages print them with %d. An NSID larger than 0x7fffffff is rendered as a negative number, which is confusing in the kernel log and makes the message hard to correlate with the namespace it talks about. Sparse NSID spaces where high NSIDs are common are the most likely to hit this. The nsid sysfs attribute has the same problem, and there it is worse because userspace parses the value. For example: $ grep . /sys/class/block/nvme0*/nsid /sys/class/block/nvme0c0n1/nsid:10 /sys/class/block/nvme0c0n2/nsid:-16 /sys/class/block/nvme0c0n3/nsid:11 /sys/class/block/nvme0c0n4/nsid:-2000000016 /sys/class/block/nvme0n1/nsid:10 /sys/class/block/nvme0n2/nsid:-16 /sys/class/block/nvme0n3/nsid:11 /sys/class/block/nvme0n4/nsid:-2000000016 $ Print all of them with %u. Several messages in these files, including two in zns.c right next to the ones being changed, already use %u, so this only makes the rest consistent with them. No functional change other than how the NSID is formatted. Fixes: |

nvme: remove stale namespaces by NSID range during scan
nvme_scan_ns_list() drops the stale namespaces in each gap in the
reported NSID list one NSID at a time. Every iteration calls
nvme_find_get_ns() to look the namespace up and removes it if it is
present. The loop runs once per NSID in the gap rather than once per
namespace actually present.
NSIDs are 32-bit, so a target with a sparse NSID space can make a
single gap spin the loop billions of times with nothing to remove.

nvme: add missing SRCU grace period in error path
nvme_alloc_ns() error path at out_unlink_ns removes ns from the
namespace head siblings list with list_del_rcu(&ns->siblings) but
does not wait for SRCU readers before freeing the namespace struct.
Multipath code iterates the head->list under srcu_read_lock() in
nvme_find_path() and nvme_mpath_revalidate_paths(), so a concurrent
reader can still hold a reference to ns when kfree(ns) runs.
The normal removal path in nvme_ns_remove() correctly calls
synchronize_srcu(&ns->head->srcu) after list_del_rcu() to wait for
in-progress readers. Add the same grace period in the error path.

nvme-fabrics: fix DHCHAP secret leak on parse failure
nvmf_parse_options() duplicates dhchap_secret and dhchap_ctrl_secret
with match_strdup() before validating the DHHC-1: representation.
If validation fails, the parser returns -EINVAL before the temporary
string in p is assigned to opts->dhchap_secret or
opts->dhchap_ctrl_secret. nvmf_create_ctrl() subsequently frees opts,
but nvmf_free_options() cannot release the unassigned temporary string.
Each rejected option therefore leaks one allocation.
This is easy to miss because valid secrets transfer ownership to opts
and are freed normally, while the malformed-secret path still returns
the expected -EINVAL to userspace.
With CONFIG_NVME_HOST_AUTH enabled, the leak is reachable before the
required-option checks and transport lookup. No NVMe-oF target or
working transport connection is required; for example, repeatedly
writing
dhchap_secret=BAD
or
dhchap_ctrl_secret=BAD
to /dev/nvme-fabrics deterministically takes the leaking parse path.
Free the temporary string before leaving both validation error paths.
Use kfree_sensitive() because the copied option may contain secret
material even when its representation is rejected, matching the
sensitive cleanup used for stored DHCHAP secrets.

ublk: clear VM_MAYWRITE on read-only ublk char device mmap
ublk_ch_mmap() rejects mmap requests with VM_WRITE set, but never
clears VM_MAYWRITE on the resulting read-only mapping. This allows

When cloning for a split, the gap only applies to the front bio since

gaps to 0 since it advanced past the checked vectors, and will start its
accounting from there on the next split check.

block: flag zoned disks with GENHD_FL_NO_PART
Zoned block devices do not support partitions. However, the partition
table is nevertheless still inspected, and any partition found ignored
with a warning in add_partition(). While this is generally not a problem,
and in fact beneficial to the user as it indicates an invalid use of a
zoned block device, scanning for a partition table on the device may
result in issuing read operations to offline zones (e.g. after a disk head
is depopulated for disks that support head management operations).
Since partitions are ignored anyway, completely disable partition scanning
for zoned gendisks by setting the flag GENHD_FL_NO_PART in __add_disk().
The existing check in add_partition() is left as-is to ensure that we
still get a warning if for whatever reason, despite GENHD_FL_NO_PART, we
still endup trying to add partitions.
Flagging zoned disks with GENHD_FL_NO_PART also has the benefit to expose
through sysfs the ext_range attribute with the value of 1 instead of the
default DISK_MAX_PARTS, thus correctly advertizing the fact that zoned
disks do not support partitions.

Rust fixes for v7.3
Toolchain and infrastructure:
- Fix KCFI failures, such as in Rust doctests, by disabling function
merging when CFI is enabled. Gary reported the LLVM bug to upstream
and it is now fixed in their mainline.
- Fix 'objtool' fallthrough warnings under the experimental
'CONFIG_RUST_INLINE_HELPERS' by passing (for the combined Rust and
helpers code) the LLVM options needed to preserve the unreachable
traps that 'rustc' normally emits.
In addition, fix 'objtool' errors when LTO is enabled on top, by
also filtering out the LTO flags (for the combined Rust and helpers
code) so that the traps are kept in place.
- Fix 'objtool' warnings by adding one more 'noreturn' function.
- Fix 'make rusttest' target when the 'rustc-dev' component is
installed and Rust >= 1.82.0, <= 1.87.0 is used.
'kernel' crate:
- 'num' module: fix soundness issue in the 'Bounded' conversion from
'bool' by restricting the conversions to unsigned 'Bounded'.
- 'jump_label' module: fix future 'make rusttest' target failures when
'ARCH=' is set to an arch different than the host's.
- 'list' module: fix incorrect 'pop_back()' comment.

tracing fixes for v7.3:
- Fix error output of boot instance creation failure Currently if a boot instance creation fails, instead of printing out the name of the instance that failed, it prints "(null)". That is because it prints "cur_str" that had already been processed by strsep(). Print the saved name instead. While at it, print the error code of the failure. - Fix use-after-free for same named historgrams Histograms can be named so that they can be used in multiple events. But if the named histogram has a variable attached, the second event that uses the named histogram which duplicates it and needs to free the original after duplication leaves the old variable in place and still visible. If another histogram uses than variable, it will use the stale one which will try to reference the freed duplicate histogram and crash the kernel. Free the duplicate variables along with the duplicated histogram data. - Check return value of kthread_run() in event self test The events self tests uses a kthread for testing but does not check if it succeeded in creating a kthread. If the kthread creation were to fail, the code will still try to call kthread_stop() on the error returned. - Fix race between reading trace_pipe and updating subbuffer size If a user is reading the trace_pipe file at the same time they update the ring buffer sub-buffer size, can cause the trace_pipe read to read stale data. Add trace_access_lock() around updating the ring buffer sub-buffer size. - Fix eventfs_inode on failure path in creation of the events directory In the creation of the "events" directory, if after allocating the eventfs_inode a failure is detected, it calls cleanup_ei() which calls free_ei(). The free_ei() will test if eventfs_inode being freed has no children. It is a bug if it does. But on the failure case of the creation of the "events" directory, the children lists have not yet been initialized and the free will trigger a warning because list_empty() on an uninitialized list returns false. Move the initialization into init_ei() where it makes more sense and makes sure that a created eventfs_inode has its lists initialized upon creation. - Check return value of kthread_run() in ftrace direct sample code The sample code that shows how to use the ftrace direct calls does not test the return of kthread_run() to see if it succeeds. Return a failure if the kthread_run() doesn't succeed. - Clear user events state on fork in case of alloc failure On fork, the child gets a pointer to the parent's user events state. It makes a copy of it then updates the child's pointer to it. But if the allocation fails, the duplication function leaves the child with a pointer to its parent's descriptor. When the child cleans up its data, it will free the parent's descriptor while the parent is still using it. In the duplication function, set the child's user_event_mm to NULL before testing if the allocation succeeded, and when it exits it will not free the parent's descriptor. - Fix retry exhaustion in simple ring buffer reader swap simple_ring_buffer_swap_reader_page() starts with retry set to 8 and post-decrements it only after a failed link replacement. On the final attempt, a successful replacement leaves retry at zero, while a failed replacement leaves it at -1. But the check for success expects the retry value to be non-zero and exits with an error on zero. This is the opposite result. Fix it. - Fail nicely when the remote swap_reader_page() returns an error Currently, if the swap_reader_page() of a remote buffer fails, it triggers a WARN_ON_ONCE() and continues normally. Instead, have it exit with an error and a pr_warn() print instead of a full WARNING. -----BEGIN PGP SIGNATURE----- iIoEABYKADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCapOC3hQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qvjkAQCGVuyK980rwiBnfenWLpeB3QjfHA8B mV0mJSlGWm1t1gEA9WWzMGbp+OHeRV2xyA+xW7OS1S58VO9OIGrzXCGqbAM= =TrF5 -----END PGP SIGNATURE----- Merge tag 'trace-v7.3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing fixes from Steven Rostedt: - Fix error output of boot instance creation failure Currently if a boot instance creation fails, instead of printing out the name of the instance that failed, it prints "(null)".

Add trace_access_lock() around updating the ring buffer sub-buffer size. - Fix eventfs_inode on failure path in creation of the events directory In the creation of the "events" directory, if after allocating the eventfs_inode a failure is detected, it calls cleanup_ei() which calls free_ei(). The free_ei() will test if eventfs_inode being freed has no children. It is a bug if it does. But on the failure case of the creation of the "events" directory, the children lists have not yet been initialized and the free will trigger a warning because list_empty() on an uninitialized list returns false. Move the initialization into init_ei() where it makes more sense and makes sure that a created eventfs_inode has its lists initialized upon creation. - Check return value of kthread_run() in ftrace direct sample code The sample code that shows how to use the ftrace direct calls does not test the return of kthread_run() to see if it succeeds. Return a failure if the kthread_run() doesn't succeed. - Clear user events state on fork in case of alloc failure On fork, the child gets a pointer to the parent's user events state. It makes a copy of it then updates the child's pointer to it. But if the allocation fails, the duplication function leaves the child with a pointer to its parent's descriptor. When the child cleans up its data, it will free the parent's descriptor while the parent is still using it. In the duplication function, set the child's user_event_mm to NULL before testing if the allocation succeeded, and when it exits it will not free the parent's descriptor. - Fix retry exhaustion in simple ring buffer reader swap simple_ring_buffer_swap_reader_page() starts with retry set to 8 and post-decrements it only after a failed link replacement. On the final attempt, a successful replacement leaves retry at zero, while a failed replacement leaves it at -1. But the check for success expects the retry value to be non-zero and exits with an error on zero. This is the opposite result. Fix it. - Fail nicely when the remote swap_reader_page() returns an error Currently, if the swap_reader_page() of a remote buffer fails, it triggers a WARN_ON_ONCE() and continues normally. Instead, have it exit with an error and a pr_warn() print instead of a full WARNING. * tag 'trace-v7.3-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: ring-buffer: Stop remote reader update when page swap fails tracing: Fix retry exhaustion in simple ring buffer reader swap tracing/user_events: Clear copied tracing state before fork duplication samples/ftrace: Fix kthread_stop() on ERR_PTR in ftrace-direct-multi-modify samples/ftrace: Fix kthread_stop() on ERR_PTR in ftrace-direct-modify eventfs: Initialize ei->children and ei->list in init_ei() tracing: Fix use-after-free in trace_pipe read on sub-buffer order change tracing: Fix crash passing ERR_PTR to kthread_stop() tracing: Fix use-after-free with same-name named triggers tracing: Fix logged instance name on creation failure |

openrisc: fix arbitrary kernel memory access via or1k_atomic syscall
sys_or1k_atomic() (syscall 244 in the "or1k" ABI) takes two user
pointers, v1 and v2, and swaps the words they point to in hand-written
assembly.
l.lwz r29,0(r4)
l.lwz r27,0(r5)
l.sw 0(r4),r27
l.sw 0(r5),r29
The pointers are not checked with access_ok(). The four memory
accesses also have no exception table entries.
A caller passes a kernel address as either pointer, and the syscall
reads from and writes to it directly.
This gives an unprivileged process a kernel read/write primitive. It
overwrites kernel data such as the sys_call_table, gaining code
execution in kernel context.
Check both pointers before entering the critical section. Add fixups
for the four memory accesses so faults on valid but unmapped user
addresses return -EFAULT.
