Inside mark_stack_slot_misc, we should not upgrade STACK_INVALID to STACK_MISC when allow_ptr_leaks is false, since invalid contents shouldn't be read unless the program has the relevant capabilities. The relaxation only makes sense when env->allow_ptr_leaks is true. However, such conversion in privileged mode becomes unnecessary, as invalid slots can be read without being upgraded to STACK_MISC. Currently, the condition is inverted (i.e. checking for true instead of false), simply remove it to restore correct behavior.

When CAP_PERFMON and CAP_SYS_ADMIN (allow_ptr_leaks) are disabled, the verifier aims to reject partial overwrite on an 8-byte stack slot that contains a spilled pointer. However, in such a scenario, it rejects all partial stack overwrites as long as the targeted stack slot is a spilled register, because it does not check if the stack slot is a spilled pointer. Incomplete checks will result in the rejection of valid programs, which spill narrower scalar values onto scalar slots, as shown below. 0: R1=ctx() R10=fp0 ; asm volatile ( @ repro.bpf.c:679 0: (7a) *(u64 *)(r10 -8) = 1 ; R10=fp0 fp-8_w=1 1: (62) *(u32 *)(r10 -8) = 1 attempt to corrupt spilled pointer on stack processed 2 insns (limit 1000000) max_states_per_insn 0 total_states 0 peak_states 0 mark_read 0. Fix this by expanding the check to not consider spilled scalar registers when rejecting the write into the stack. Previous discussion on this patch is at link [0].

Add a __caps_unpriv annotation so that tests requiring specific capabilities while dropping the rest can conveniently specify them during selftest declaration instead of munging with capabilities at runtime from the testing binary. While at it, let us convert test_verifier_mtu to use this new support instead. Since we do not want to include linux/capability.h, we only defined the four main capabilities BPF subsystem deals with in bpf_misc.h for use in tests. If the user passes a CAP_SYS_NICE or anything else that's not defined in the header, capability parsing code will return a warning. Also reject strtol returning 0. CAP_CHOWN = 0 but we'll never need to use it, and strtol doesn't errno on failed conversion. Fail the test in such a case. The original diff for this idea is available at link [0].

The NVMe specification states that MAXCMD is mandatory for NVMe-over-Fabrics implementations. However, some NVMe/TCP and NVMe/FC arrays from major vendors have buggy firmware that reports MAXCMD as zero in the Identify Controller data structure. Currently, the implementation closes the connection in such cases, completely preventing the host from connecting to the target. Fix the issue by printing a clear error message about the firmware bug and allowing the connection to proceed. It assumes that the target supports a MAXCMD value of SQSIZE + 1. If any issues arise, the user can manually adjust SQSIZE to mitigate them.

System crash is observed with stack trace warning of use after free. There are 2 signals to tell dpc_thread to terminate (UNLOADING flag and kthread_stop). On setting the UNLOADING flag when dpc_thread happens to run at the time and sees the flag, this causes dpc_thread to exit and clean up itself. When kthread_stop is called for final cleanup, this causes use after free. Remove UNLOADING signal to terminate dpc_thread. Use the kthread_stop as the main signal to exit dpc_thread.

Fix a use-after-free bug in sg_release(), detected by syzbot with KASAN: BUG: KASAN: slab-use-after-free in lock_release+0x151/0xa30 kernel/locking/lockdep.c:5838 __mutex_unlock_slowpath+0xe2/0x750 kernel/locking/mutex.c:912 sg_release+0x1f4/0x2e0 drivers/scsi/sg.c:407 In sg_release(), the function kref_put(&sfp->f_ref, sg_remove_sfp) is called before releasing the open_rel_lock mutex. The kref_put() call may decrement the reference count of sfp to zero, triggering its cleanup through sg_remove_sfp(). This cleanup includes scheduling deferred work via sg_remove_sfp_usercontext(), which ultimately frees sfp. After kref_put(), sg_release() continues to unlock open_rel_lock and may reference sfp or sdp. If sfp has already been freed, this results in a slab-use-after-free error. Move the kref_put(&sfp->f_ref, sg_remove_sfp) call after unlocking the open_rel_lock mutex. This ensures: - No references to sfp or sdp occur after the reference count is decremented. - Cleanup functions such as sg_remove_sfp() and sg_remove_sfp_usercontext() can safely execute without impacting the mutex handling in sg_release(). The fix has been tested and validated by syzbot. This patch closes the bug reported at the following syzkaller link and ensures proper sequencing of resource cleanup and mutex operations, eliminating the risk of use-after-free errors in sg_release().

…play() The first argument of the rz_ssi_stream_is_play() is not used. Remove it. Reviewed-by: Geert Uytterhoeven <[email protected]> Signed-off-by: Claudiu Beznea <[email protected]> Link: https://patch.msgid.link/[email protected] Signed-off-by: Mark Brown <[email protected]>
Use readl_poll_timeout_atomic() instead of hardcoding something similar. While at it replace dev_info() with dev_warn_ratelimited() as the rz_ssi_set_idle() can also be called from IRQ context and if the SSI idle is not properly set this is at least a warning for user.

…uspend the SSI The ASoC subsystem takes care of runtime resume/suspend the audio devices when needed. Just enable the runtime PM on the SSI driver and let the subsystem runtime resume/suspend it.

The code initially issued software reset on SNDRV_PCM_TRIGGER_START action only before starting the first stream. This can be easily moved to hw_params() as the action is similar to setting the clocks. Moreover, according to the hardware manual (Table 35.7 Bits Initialized by Software Reset of the SSIFCR.SSIRST Bit) the software reset action acts also on the clock dividers bits. Due to this issue the software reset in hw_params() before configuring the clock dividers. This also simplifies the code in trigger API.

The SSIF-2 IP is available on the Renesas RZ/G3S SoC. The Renesas RZ/G3S SoC supports a power-saving mode where power to most of the SoC components is turned off. Add suspend/resume support to the SSIF-2 driver to support this power-saving mode. On SNDRV_PCM_TRIGGER_SUSPEND trigger the SSI is stopped (the stream user pointer is left untouched to avoid breaking user space and the dma buffer pointer is set to zero), on SNDRV_PCM_TRIGGER_RESUME software reset is issued for the SSIF-2 IP and the clocks are re-configured.

One specific test condition: the default registers of p[j].reg ~ p[j+3].reg are 0, TASDEVICE_REG(0x00, 0x14, 0x38)(PLT_FLAG_REG), TASDEVICE_REG(0x00, 0x14, 0x40)(SINEGAIN_REG), and TASDEVICE_REG(0x00, 0x14, 0x44)(SINEGAIN2_REG). After first calibration, they are freshed to TASDEVICE_REG(0x00, 0x1a, 0x20), TASDEVICE_REG(0x00, 0x16, 0x58)(PLT_FLAG_REG), TASDEVICE_REG(0x00, 0x14, 0x44)(SINEGAIN_REG), and TASDEVICE_REG(0x00, 0x16, 0x64)(SINEGAIN2_REG) via "Calibration Start" kcontrol. In second calibration, the p[j].reg ~ p[j+3].reg have already become tas2781_cali_start_reg. However, p[j+2].reg, TASDEVICE_REG(0x00, 0x14, 0x44)(SINEGAIN_REG), will be freshed to TASDEVICE_REG(0x00, 0x16, 0x64), which is the third register in the input params of the kcontrol. This is why only first calibration can work, the second-time, third-time or more-time calibration always failed without reboot. Of course, if no p[j].reg is in the list of tas2781_cali_start_reg, this stress test can work well.

Mark the list of registers passed into regmap_multi_reg_read() as a pointer to const. This allows the caller to define the register list as const data. This requires making the same change to _regmap_bulk_read(), which is called by regmap_multi_reg_read().

However in the case the array is completely full this will lead to an access 1 past the end of the array, expand the array by one entry to include a space for a terminator.
