From 891f4d27369f54d4284545b884eeb8c610802ab0 Mon Sep 17 00:00:00 2001 From: Guillem Jover Date: Wed, 21 Aug 2019 04:36:09 +0200 Subject: [PATCH libaio 0/3] Fix io_pgetevents() wrapper and test case Hi! This series completely fixes 22.t on all currently available Debian architectures. I only managed to test a fixed kernel yesterday, the fix for which I'm sending separately, and the libaio patch works fine with that too. I considered detecting whether we might be running in kernel compat mode by using personality(2), or selecting a workaround variant via an ifunc resolver to avoid somewwhat penalizing libaio users running on broken kernels, but it didn't seem worth it, as IMO the proposed patch should be considered just a temporary workaround until fixed kernels are in wide-spread use. BTW, while going over kernel and userland I noticed libaio might perhaps need to grow wrappers for the new time32/time64 syscalls? Thanks, Guillem Guillem Jover (3): harness: Print better error messages on error conditions in 22.t Fix io_pgetevents() syscall wrapper on 32-bit userland on 64-bit kernels harness: Skip the test if io_pgetevents() is not implemented harness/cases/22.t | 19 +++++++++++++------ src/io_pgetevents.c | 38 +++++++++++++++++++++++++++++++------- src/libaio.h | 12 ++++++++++++ 3 files changed, 56 insertions(+), 13 deletions(-) -- 2.23.0
