[Qemu-devel] [Bug 1075339] Re: linux-user emulation of setsockopt ignores optlen

[Peter Maydell]

We fixed our setsockopt emulation to correctly convert timeval
parameters for SO_RCVTIMEO and SO_SNDTIMEO back in 2013.

Title:
  linux-user emulation of setsockopt ignores optlen

Status in QEMU:
  Fix Released

Bug description:
  setsockopt always treats the argument as a 4-byte int. This breaks
  timeout options (for which it's an 8- or 16-byte timeval structure,
  depending on word size) and possibly other socket options. int is
  probably a safe default, but options whose values are other types need
  special-case conversion code.
