[PATCH v3 0/2] Missing endianness conversions in user mode
Posted by Mathis Marion 1 year ago
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.

v3:
- remove patches "linux-user: fix timerfd read endianness conversion"
  and "linux-user: add target to host netlink conversions" as they were
  integrated.
- remove sin6_flowinfo endianness conversion
- use NLA_TYPE_MASK instead of ~NLA_F_NESTED

v2:
- remove context from target_to_host_for_each_nlattr()

Mathis Marion (2):
  linux-user: fix sockaddr_in6 endianness
  linux-user: handle netlink flag NLA_F_NESTED
