[PATCH v3 0/9] MR6: Avoid performance degradation due to vDSO unmapping (BZ#52313)
by Jinoh Kang (＠iamahuman) April 30, 2022

April 30, 2022

Commit f558741fabc116534fa598aa890ffed683a7153b removes vDSO if it conflicts with reserved ranges: > Remove the AT_SYSINFO and AT_SYSINFO_EHDR values if the sysinfo page > is in one of our reserved ranges. However, missing vDSO leads to performance issues on some syscalls (e.g. clock_gettime, gettimeofday) and may even lead to crash when run with some ancient C libraries that does not supply a custom signal restorer. vDSO pages can clash with reserved ranges especially in a 32-bit address space with address space layout randomization (ASLR) turned on. Recent versions of the Linux kernel introduced support for mremap()-ping vDSO pages, partly in an effort to support checkpoint restore in userspace (CRIU). Special programs that require specific memory layout constraints (such as Wine preloader) can take advantage of this support to modify the address space to meet its requirements. The following test script has been used to test each changes (use with `git rebase --exec=...`): ```sh set -e make -C ../wine64-build -j5 make -C ../wine32-build -j5 cd ../wine64-build export WINEPRELOADREMAPSTACK export WINEPRELOADREMAPVDSO for WINEPRELOADREMAPSTACK in skip never always force auto on-demand '' do for WINEPRELOADREMAPVDSO in skip never always force auto on-demand '' do ./loader/wine64 wineboot ./loader/wine wineboot done done ``` -- v3: loader: Switch stack if the old stack address is in reserved range. loader: Relocate sigpage on conflict with reserved ranges in ARM. loader: Relocate vDSO on conflict with reserved ranges. loader: Fix return type of get_auxiliary(). loader: Don't clobber existing memory mappings when reserving addresses. loader: Explicitly munmap() the preloader's ELF EHDR. loader: Generalise is_addr_reserved to find overlapping address ranges. loader: Refactor number parsing to own function. loader: Refactor argv/envp/auxv management. https://gitlab.winehq.org/wine/wine/-/merge_requests/6

[PATCH 3/6] wineoss: Introduce a helper to retrieve the time.
by Huw Davies April 29, 2022

April 29, 2022

The motivation is that this will need to be called from a non-Win32 thread and so shouldn't use the Win32 API. An added benefit is that it will eliminate the 16ms jitter associated with GetTickCount().

[PATCH 1/6] wineoss: Introduce a notification thread.

Currently the thread just blocks until told to quit by midi_release. Eventually this thread will dispatch the MIM_DATA and MIM_LONGDATA notifications.
