| H A D | hpimsginit.c | diff f9d94b57e30fd1575b4935045b32d738668aa74b Tue Apr 24 01:01:48 CDT 2018 Takashi Iwai <tiwai@suse.de> ALSA: asihpi: Hardening for potential Spectre v1
As recently Smatch suggested, a couple of places in ASIHPI driver may
expand the array directly from the user-space value with speculation:
sound/pci/asihpi/hpimsginit.c:70 hpi_init_response() warn: potential spectre issue 'res_size' (local cap)
sound/pci/asihpi/hpioctl.c:189 asihpi_hpi_ioctl() warn: potential spectre issue 'adapters'
This patch puts array_index_nospec() for hardening against them.
