Subject: [PATCH v2 0/4] Missing endianness conversions in user mode
Date: Mon, 20 Feb 2023 09:58:18 +0100	[thread overview]
Message-ID: <20230220085822.626798-1-Mathis.Marion@silabs.com> (raw)

From: Mathis Marion <mathis.marion@silabs.com>

For a bit of context, I was trying to test a network border router [1]
daemon using the MIPS architecture (see [2]). I didn't have access to
real MIPS hardware so I figured I would emulate it using QEMU user mode.
I ran into a couple of problems all related to endianness conversion for
syscalls between host and target as MIPS is big endian and my x86 host
is little.

[2]: https://github.com/SiliconLabs/wisun-br-linux/issues/5

v2:
- remove context from target_to_host_for_each_nlattr()

Mathis Marion (4):
  linux-user: fix timerfd read endianness conversion
  linux-user: fix sockaddr_in6 endianness
  linux-user: add target to host netlink conversions
  linux-user: handle netlink flag NLA_F_NESTED
