This change introduced some failures for applications with errors like - accesing bytes above the brk heap address on the same page, - freeing memory below the initial brk address, and introduced a behaviour which isn't done by the kernel (e.g. zeroing memory above brk). This patch series fixes those issues and has been tested with existing programs (e.g. upx). Additionally one patch fixes running static armhf executables (e.g. fstype) which was broken since qemu-8.0. Changes in v2: - dropped patch to revert d28b3c90cfad ("linux-user: Make sure initial brk(0) is page-aligned") - rephrased some commit messages - fixed Cc email addresses, added new ones - added R-b tags Helge ---------------------------------------------------------------- Helge Deller (5): linux-user: Fix qemu brk() to not zero bytes on current page linux-user: Prohibit brk() to to shrink below initial heap address linux-user: Fix signed math overflow in brk() syscall linux-user: Fix strace output for old_mmap linux-user: Fix qemu-arm to run static armhf binaries linux-user/elfload.c | 7 +++++++ linux-user/strace.c | 49 ++++++++++++++++++++++++++++++++++++++++---- linux-user/syscall.c | 23 +++++++++++++-------- 3 files changed, 66 insertions(+), 13 deletions(-) -- 2.41.0
