[PATCH OLK-5.10] mm: only enforce minimum stack gap size if it's sensible
by Liu Shixin 09 Dec '24

09 Dec '24

From: David Gow <davidgow(a)google.com> stable inclusion from stable-v5.10.227 commit 52f7cab2903959316c907441100adef85eba88a7 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IB8I85 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 69b50d4351ed924f29e3d46b159e28f70dfc707f upstream. The generic mmap_base code tries to leave a gap between the top of the stack and the mmap base address, but enforces a minimum gap size (MIN_GAP) of 128MB, which is too large on some setups. In particular, on arm tasks without ADDR_LIMIT_32BIT, the STACK_TOP value is less than 128MB, so it's impossible to fit such a gap in. Only enforce this minimum if MIN_GAP < MAX_GAP, as we'd prefer to honour MAX_GAP, which is defined proportionally, so scales better and always leaves us with both _some_ stack space and some room for mmap. This fixes the usercopy KUnit test suite on 32-bit arm, as it doesn't set any personality flags so gets the default (in this case 26-bit) task size. This test can be run with: ./tools/testing/kunit/kunit.py run --arch arm usercopy --make_options LLVM=1 Link: https://lkml.kernel.org/r/20240803074642.1849623-2-davidgow@google.com Fixes: dba79c3df4a2 ("arm: use generic mmap top-down layout and brk randomization") Signed-off-by: David Gow <davidgow(a)google.com> Reviewed-by: Kees Cook <kees(a)kernel.org> Cc: Alexandre Ghiti <alex(a)ghiti.fr> Cc: Linus Walleij <linus.walleij(a)linaro.org> Cc: Luis Chamberlain <mcgrof(a)kernel.org> Cc: Mark Rutland <mark.rutland(a)arm.com> Cc: Russell King <linux(a)armlinux.org.uk> Cc: <stable(a)vger.kernel.org> Signed-off-by: Andrew Morton <akpm(a)linux-foundation.org> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> Signed-off-by: Liu Shixin <liushixin2(a)huawei.com> --- mm/util.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/mm/util.c b/mm/util.c index 63d510d39c47..b2e0ae3c65aa 100644 --- a/mm/util.c +++ b/mm/util.c @@ -420,7 +420,7 @@ static unsigned long mmap_base(unsigned long rnd, struct rlimit *rlim_stack) if (gap + pad > gap) gap += pad; - if (gap < MIN_GAP) + if (gap < MIN_GAP && MIN_GAP < MAX_GAP) gap = MIN_GAP; else if (gap > MAX_GAP) gap = MAX_GAP; -- 2.34.1
