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.

Akihiko Odaki (6):
linux-user: Unset MAP_FIXED_NOREPLACE for host
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 TASK_UNMAPPED_BASE in $guest/target_mman.h
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
linux-user: Do not adjust image mapping for host page size
linux-user: Do not adjust zero_bss for host page size
linux-user: Use zero_bss for PT_LOAD with no file contents too
