The ioctl numeric values are platform-independent and determined by
the file include/uapi/linux/sockios.h in Linux kernel source code:
#define SIOCETHTOOL 0x8946
These ioctls get (or set) various structures pointed by the field
ifr_data in the structure ifreq depending on the first 4 bytes of
Flexible arrays may appear in the last field of a struct and are heavily
used in the ioctl(SIOCETHTOOL) system call on Linux. E.g.
struct ethtool_regs {
__u32 cmd;
__u32 version; /* driver-specific, indicates different chips/revs */
__u32 len; /* bytes */
__u8da
Hi Riku and Laurent,
These two patches together implements the SIOCETHTOOL ioctl operations. Many of
the kernel structures in this operations make use of flexible arrays (array with
no size / zero size at the end of the structure), so I extended thunk to handle
these fields natively.
This patch s
This change supports SO_TIMESTAMPNS_OLD/NEW and SO_TIMESTAMPING_OLD/NEW
for setsocketopt() with SOL_SOCKET. Based on the SO_TIMESTAMP_OLD/NEW
framework. The three pairs share the same flag `SOCK_TSTAMP_NEW` in
linux kernel for deciding if the old or the new format is used.

Both guest options map to host SO_TIMESTAMP while keeping a global bit to
remember if the guest expects the old or the new format. Don't support
programs mixing two formats.
Added a multiarch test to verify.

Besides /proc/self|, files under /proc/thread-self and
/proc/self|/task/ also expose host information to the guest
program. This patch adds them to the hijack infrastracture. Note that
is_proc_myself() does not check if the matches the current thread
and is thus only suitable for procfs files that
timer_getoverrun returns the "overrun count" for the timer, which is not
a file descriptor and thus should not call fd_trans_unregister on it.
