bus: fsl-mc: Replace deprecated strncpy() with strscpy_pad()
`strncpy` is deprecated for use on NUL-terminated destination strings [1]. We need to prefer more robust and less ambiguous string interfaces. `obj_desc->(type|label)` are expected to be NUL-terminated strings as per "include/linux/fsl/mc.h +143" | ... | * struct fsl_mc_obj_desc - Object descriptor | * @type: Type of object: NULL terminated string | ... It seems `cmd_params->obj_type` is also expected to be a NUL-terminated string. A suitable replacement is `strscpy_pad` due to the fact that it guarantees NUL-termination on the destination buffer whilst keeping the NUL-padding behavior that `strncpy` provides. Padding may not strictly be necessary but let's opt to keep it as this ensures no functional change.

auxdisplay: panel: Replace deprecated strncpy() with strtomem_pad()
`strncpy` is deprecated and as such we should prefer more robust and
less ambiguous interfaces.
In this case, all of `press_str`, `repeat_str` and `release_str` are
explicitly marked as nonstring:
| struct { /* valid when type == INPUT_TYPE_KBD */
| char press_str[sizeof(void *) + sizeof(int)] __nonstring;
| char repeat_str[sizeof(void *) + sizeof(int)] __nonstring;
| char release_str[sizeof(void *) + sizeof(int)] __nonstring;
| } kbd;
... which makes `strtomem_pad` a suitable replacement as it is
functionally the same whilst being more obvious about its behavior.

um,ethertap: Replace deprecated strncpy() with strscpy()
`strncpy` is deprecated for use on NUL-terminated destination strings [1].
`gate_buf` should always be NUL-terminated and does not require
NUL-padding. It is used as a string arg inside an argv array given to
`run_helper()`. Due to this, let's use `strscpy` as it guarantees
NUL-terminated on the destination buffer preventing potential buffer
overreads [2].
This exact invocation was changed from `strcpy` to `strncpy` in commit

groups: Convert group_info.usage to refcount_t
atomic_t variables are currently used to implement reference counters with the following properties: - counter is initialized to 1 using atomic_set() - a resource is freed upon counter reaching zero - once counter reaches zero, its further increments aren't allowed - counter schema uses basic atomic operations (set, inc, inc_not_zero, dec_and_test, etc.) Such atomic variables should be converted to a newly provided refcount_t type and API that prevents accidental counter overflows and underflows. This is important since overflows and underflows can lead to use-after-free situation and be exploitable. The variable group_info.usage is used as pure reference counter. Convert it to refcount_t and fix up the operations. **Important note for maintainers: Some functions from refcount_t API defined in refcount.h have different memory ordering guarantees than their atomic counterparts. Please check Documentation/core-api/refcount-vs-atomic.rst for more information. Normally the differences should not matter since refcount_t provides enough guarantees to satisfy the refcounting use cases, but in some rare cases it might matter. Please double check that you don't have some undocumented memory guarantees for this variable usage. For the group_info.usage it might make a difference in following places: - put_group_info(): decrement in refcount_dec_and_test() only provides RELEASE ordering and ACQUIRE ordering on success vs. fully ordered atomic counterpart Suggested-by: Kees Cook <keescook@chromium.org> Signed-off-by: Elena Reshetova <elena.reshetova@intel.com> Reviewed-by: David Windsor <dwindsor@gmail.com> Reviewed-by: Hans Liljestrand <ishkamiel@gmail.com> Link: https://lore.kernel.org/r/20230818041456.gonna.009-kees@kernel.org Signed-off-by: Kees Cook <keescook@chromium.org> |

accel/ivpu: Annotate struct ivpu_job with __counted_by
Prepare for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add __counted_by for struct ivpu_job.

selftests/lkdtm: Disable CONFIG_UBSAN_TRAP in test config
The lkdtm selftest config fragment enables CONFIG_UBSAN_TRAP to make the
ARRAY_BOUNDS test kill the calling process when an out-of-bound access
is detected by UBSAN. However, after this [1] commit, UBSAN is triggered
under many new scenarios that weren't detected before, such as in struct
definitions with fixed-size trailing arrays used as flexible arrays. As
a result, CONFIG_UBSAN_TRAP=y has become a very aggressive option to
enable except for specific situations.
`make kselftest-merge` applies CONFIG_UBSAN_TRAP=y to the kernel config
for all selftests, which makes many of them fail because of system hangs
during boot.
This change removes the config option from the lkdtm kselftest and
configures the ARRAY_BOUNDS test to look for UBSAN reports rather than
relying on the calling process being killed.

lkdtm/bugs: add test for panic() with stuck secondary CPUs
Upon a panic() the kernel will use either smp_send_stop() or crash_smp_send_stop() to attempt to stop secondary CPUs via an IPI, which may or may not be an NMI. Generally it's preferable that this is an NMI so that CPUs can be stopped in as many situations as possible, but it's not always possible to provide an NMI, and there are cases where CPUs may be unable to handle the NMI regardless. This patch adds a test for panic() where all other CPUs are stuck with interrupts disabled, which can be used to check whether the kernel gracefully handles CPUs failing to respond to a stop, and whether NMIs actually work to stop CPUs. For example, on arm64 *without* an NMI, this results in: | # echo PANIC_STOP_IRQOFF > /sys/kernel/debug/provoke-crash/DIRECT | lkdtm: Performing direct entry PANIC_STOP_IRQOFF | Kernel panic - not syncing: panic stop irqoff test | CPU: 2 PID: 24 Comm: migration/2 Not tainted 6.5.0-rc3-00077-ge6c782389895-dirty #4 | Hardware name: QEMU QEMU Virtual Machine, BIOS 0.0.0 02/06/2015 | Stopper: multi_cpu_stop+0x0/0x1a0 <- stop_machine_cpuslocked+0x158/0x1a4 | Call trace: | dump_backtrace+0x94/0xec | show_stack+0x18/0x24 | dump_stack_lvl+0x74/0xc0 | dump_stack+0x18/0x24 | panic+0x358/0x3e8 | lkdtm_PANIC+0x0/0x18 | multi_cpu_stop+0x9c/0x1a0 | cpu_stopper_thread+0x84/0x118 | smpboot_thread_fn+0x224/0x248 | kthread+0x114/0x118 | ret_from_fork+0x10/0x20 | SMP: stopping secondary CPUs | SMP: failed to stop secondary CPUs 0-3 | Kernel Offset: 0x401cf3490000 from 0xffff80008000000c0 | PHYS_OFFSET: 0x40000000 | CPU features: 0x00000000,68c167a1,cce6773f | Memory Limit: none | ---[ end Kernel panic - not syncing: panic stop irqoff test ]--- Note the "failed to stop secondary CPUs 0-3" message.

kobject: Replace strlcpy with strscpy
strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). Direct replacement is safe here since return value of -errno is used to check for truncation instead of sizeof(dest).

hardening: Provide Kconfig fragments for basic options
Inspired by Salvatore Mesoraca's earlier[1] efforts to provide some in-tree guidance for kernel hardening Kconfig options, add a new fragment named "hardening-basic.config" (along with some arch-specific fragments) that enable a basic set of kernel hardening options that have the least (or no) performance impact and remove a reasonable set of legacy APIs. Using this fragment is as simple as running "make hardening.config". More extreme fragments can be added[2] in the future to cover all the recognized hardening options, and more per-architecture files can be added too. For now, document the fragments directly via comments. Perhaps .rst documentation can be generated from them in the future (rather than the other way around).

x86/purgatory: Remove LTO flags
-flto* implies -ffunction-sections. With LTO enabled, ld.lld generates
multiple .text sections for purgatory.ro:

[19] .text.sha224_fina PROGBITS 0000000000000000 00002cc0
This causes WARNING from kexec_purgatory_setup_sechdrs():
WARNING: CPU: 26 PID: 110894 at kernel/kexec_file.c:919
kexec_load_purgatory+0x37f/0x390
Fix this by disabling LTO for purgatory.
[ AFAICT, x86 is the only arch that supports LTO and purgatory. ]
We could also fix this with an explicit linker script to rejoin .text.*
sections back into .text. However, given the benefit of LTOing purgatory
is small, simply disable the production of more .text.* sections for now.

x86/boot/compressed: Reserve more memory for page tables
The decompressor has a hard limit on the number of page tables it can
allocate. This limit is defined at compile-time and will cause boot
failure if it is reached.
The kernel is very strict and calculates the limit precisely for the
worst-case scenario based on the current configuration. However, it is
easy to forget to adjust the limit when a new use-case arises. The
worst-case scenario is rarely encountered during sanity checks.
In the case of enabling 5-level paging, a use-case was overlooked. The
limit needs to be increased by one to accommodate the additional level.
This oversight went unnoticed until Aaron attempted to run the kernel
via kexec with 5-level paging and unaccepted memory enabled.
Update wost-case calculations to include 5-level paging.
To address this issue, let's allocate some extra space for page tables.
128K should be sufficient for any use-case. The logic can be simplified
by using a single value for all kernel configurations.
[ Also add a warning, should this memory run low - by Dave Hansen. ]

ata: libata-core: fetch sense data for successful commands iff CDL enabled
Currently, we fetch sense data for a _successful_ command if either: 1) Command was NCQ and ATA_DFLAG_CDL_ENABLED flag set (flag ATA_DFLAG_CDL_ENABLED will only be set if the Successful NCQ command sense data supported bit is set); or 2) Command was non-NCQ and regular sense data reporting is enabled. This means that case 2) will trigger for a non-NCQ command which has ATA_SENSE bit set, regardless if CDL is enabled or not. This decision was by design. If the device reports that it has sense data available, it makes sense to fetch that sense data, since the sk/asc/ascq could be important information regardless if CDL is enabled or not. However, the fetching of sense data for a successful command is done via ATA EH. Considering how intricate the ATA EH is, we really do not want to invoke ATA EH unless absolutely needed.

ata: libata-eh: do not clear ATA_PFLAG_EH_PENDING in ata_eh_reset()
ata_scsi_port_error_handler() starts off by clearing ATA_PFLAG_EH_PENDING, before calling ap->ops->error_handler() (without holding the ap->lock). If an error IRQ is received while ap->ops->error_handler() is running, the irq handler will set ATA_PFLAG_EH_PENDING. Once ap->ops->error_handler() returns, ata_scsi_port_error_handler() checks if ATA_PFLAG_EH_PENDING is set, and if it is, another iteration of ATA EH is performed. The problem is that ATA_PFLAG_EH_PENDING is not only cleared by ata_scsi_port_error_handler(), it is also cleared by ata_eh_reset(). ata_eh_reset() is called by ap->ops->error_handler(). This additional clearing done by ata_eh_reset() breaks the whole retry logic in ata_scsi_port_error_handler(). Thus, if an error IRQ is received while ap->ops->error_handler() is running, the port will currently remain frozen and will never get re-enabled. The additional clearing in ata_eh_reset() was introduced in commit |

linux-kselftest-fixes-6.6-rc2
This kselftest fixes update for Linux 6.6-rc2 consists of important
fixes to user_events test and ftrace test.
user_events test has been enabled for default run in Linux 6.6-rc1. The
following fixes are for bugs found since then:
- adds checks for dependencies and skips the test. user_events test
requires root access, and tracefs and user_events enabled. It leaves
tracefs mounted and a fix is in progress for that missing piece.
- creates user_events test-specific Kconfig fragments.
ftrace test fixes:
- unmounts tracefs for recovering environment. Fix identified during the
above mentioned user_events dependencies fix.
- adds softlink to latest log directory improving usage.

Thermal control updates for 6.6-rc2
- Unbreak disabled trip point check in handle_thermal_trip() that may
cause it to skip enabled trip points (Rafael Wysocki).
- Add missing of_node_put() to of_find_trip_id() and
thermal_of_for_each_cooling_maps() that each break out of a
for_each_child_of_node() loop without dropping the reference to
the child object (Julia Lawall).
- Constify the recently added trip argument of the .get_trend() thermal
zone callback (Rafael Wysocki).

dm: don't attempt to queue IO under RCU protection
dm looks up the table for IO based on the request type, with an
assumption that if the request is marked REQ_NOWAIT, it's fine to
attempt to submit that IO while under RCU read lock protection. This
is not OK, as REQ_NOWAIT just means that we should not be sleeping
waiting on other IO, it does not mean that we can't potentially
schedule.
A simple test case demonstrates this quite nicely:
int main(int argc, char *argv[])
{
struct iovec iov;
int fd;
fd = open("/dev/dm-0", O_RDONLY | O_DIRECT);
posix_memalign(&iov.iov_base, 4096, 4096);
iov.iov_len = 4096;
preadv2(fd, &iov, 1, 0, RWF_NOWAIT);
return 0;
}
which will instantly spew:
BUG: sleeping function called from invalid context at include/linux/sched/mm.h:306

where in fact it is dm itself that attempts to allocate a bio clone with
GFP_NOIO under the rcu read lock, regardless of the request type.
Fix this by getting rid of the special casing for REQ_NOWAIT, and just
use the normal SRCU protected table lookup. Get rid of the bio based
table locking helpers at the same time, as they are now unused.
