Subject: [PATCH for-8.1 v8 00/17] linux-user: brk fixes
Date: Thu,  3 Aug 2023 18:45:00 -0700	[thread overview]
Message-ID: <20230804014517.6361-1-richard.henderson@linaro.org> (raw)

Changes for v8:
  * Remove adjustments to the image mapping for host page size.
    Instead, rely on target_mmap to do its job in that respect.
    This was the root cause of the 64k host page size issues.

Please review.

  linux-user: Fix MAP_FIXED_NOREPLACE on old kernels
  linux-user: Do not call get_errno() in do_brk()
  linux-user: Use MAP_FIXED_NOREPLACE for do_brk()
  linux-user: Do nothing if too small brk is specified
  linux-user: Do not align brk with host page size

Helge Deller (1):
  linux-user: Adjust initial brk when interpreter is close to executable

Richard Henderson (10):
  linux-user: Remove last_brk
  linux-user: Adjust task_unmapped_base for reserved_va

  linux-user: Define ELF_ET_DYN_BASE in $guest/target_mman.h
  linux-user: Use MAP_FIXED_NOREPLACE for initial image mmap
  linux-user: Use elf_et_dyn_base for ET_DYN with interpreter
  linux-user: Properly set image_info.brk in flatload
