-Subject: [PATCH] linux-user: fix to handle variably sized SIOCGSTAMP with new
- kernels
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The SIOCGSTAMP symbol was previously defined in the
-asm-generic/sockios.h header file. QEMU sees that header
-indirectly via sys/socket.h
-
-In linux kernel commit 0768e17073dc527ccd18ed5f96ce85f9985e9115
-the asm-generic/sockios.h header no longer defines SIOCGSTAMP.
-Instead it provides only SIOCGSTAMP_OLD, which only uses a
-32-bit time_t on 32-bit architectures.
-
-The linux/sockios.h header then defines SIOCGSTAMP using
-either SIOCGSTAMP_OLD or SIOCGSTAMP_NEW as appropriate. If
-SIOCGSTAMP_NEW is used, then the tv_sec field is 64-bit even
-on 32-bit architectures
-
-To cope with this we must now convert the old and new type from
-the target to the host one.
