[BUG] ARM32 Idle stack underaligned #18558
Description
Description / Steps to reproduce the issue
The ARM idle stack for boards based on armv6/armv7 cores can potentially only be aligned to 4-byte boundarys instead of 8-byte stack alignment called out by AAPCS32. Normally this isn't an issue but vararg processing by GCC forcibly aligns accesses of long long on 8-byte boundaries.
While adding code to remove the "Missing logic" warning in stm32_irq.c:152 I ran into a data abortbus fault exception while calling syslog() from the idle task on a nucleo-stm32h743zi2 board(based on stm32h7). Applying the same changtes to nucleo-f446re(stm32) and nuclio-f767zi(stm32f7) also caused the exception.
The underlying issue occurs due to calling stm32_dumpnvic from the idletask with SYSLOG_TIMESTAMP enabled, but only when the Idlestak is not aligned to an 8-byte bvoundary. The issue is due to invoking "x = va_arg(ap, unsigned long long);" in vsprintf_internal (lib_libvsprintf.c:1061) which aligns ap before accessing the long long:
Breakpoint 5, vsprintf_internal (stream=stream@entry=0x20005390, arglist=0x0,
numargs=0, fmt=0x8018bf2 ".%06ld] [%6s] %s: ",
fmt@entry=0x8005817 <lib_sprintf_internal+22> "...",
ap=..., ap@entry=..., numargs=0, arglist=0x0)
at stream/lib_libvsprintf.c:1061
1061 x = va_arg(ap, unsigned long long);
p ap
$18 = {__ap = 0x2000536c}
(gdb) x/5i $pc
=> 0x800563a <vsprintf_internal+782>: add.w r9, r9, #7
0x800563e <vsprintf_internal+786>: bic.w r9, r9, #7 # align ap
0x8005642 <vsprintf_internal+790>: mov r7, r9
0x8005644 <vsprintf_internal+792>: ldr.w r1, [r9, #4]
0x8005648 <vsprintf_internal+796>: ldr.w r0, [r7], #8
(gdb) p/x $r9
$19 = 0x2000536c
(gdb) s
1108 flags &= ~(FL_PLUS | FL_SPACE);
(gdb) p ap
$20 = {__ap = 0x20005378}
(gdb) p/x $r7
$21 = 0x20005378
(gdb)
This works fine if the stack is aligned on an 8-byte boundary (which all other task/user stacks currently are due to MM_DEFAULT_ALIGNMENT being 8). But if the idletask stack is not aligned, ap ends up incremented by 12 causing access to any following vararg in vsprintf_internal to be offset by 4 bytes resulting in potential exceptions.
A clean fix would be to increase the alignment in the .bss section to 8 in the linker description file (since the idlestack immediately follows .bss starting at _ebss). I've tested this fix on nucleo-743zi2 (based on stm32h7), nucleo-h767zi (based on stm32f7), and nucleo-f446re (based on stm32), all with success.
I reproduced the issue using the following steps in nuttx (git hash 55e752a) and nuttx-apps(git hash 8cd9e9acc23d35a8bcc5f38e7f49cbb05951675e) but believe it can be reproduced in other STM32 versions that enable ARCH_IRQINFO, USB_DEBUG_INFO, and SYSLOG_TIMESTAMP, (but have not verified if only those options are required):
tools/configure.sh -l nucleo-h743zi2:jumbo
kconfig-tweak --file .config --enable ARCH_IRQPRIO
kconfig-tweak --file .config --enable DEBUG_IRQ
kconfig-tweak --file .config --disable DEBUG_IRQ_ERROR
kconfig-tweak --file .config --disable DEBUG_IRQ_WARN
kconfig-tweak --file .config --enable DEBUG_IRQ_INFO
make -j $(npproc)
Triggering the issue requies that _ebss(and thereby the idle stack) is not 8-byte aligned (determined by "nm nuttx | grep _ebss"). If _ebss is aligned, you can force non-8-byte alignment by applying the following (artifical) patch to add a pointless global variable at/near end of .bss section to bump _ebss:
