This is a simple utility used to test SPI functionality. It could stand
growing options to support using other test data patterns; this initial
version only issues full duplex transfers, which rules out 3WIRE or

The spidev driver doesn't currently expose all SPI communications modes to
userspace. This passes them all through to the driver.Two of them are potentially troublesome, in the sense that they could cause
hardware conflicts on shared busses. It might be appropriate to add some
privilege checks for for those modes.Signed-off-by: Anton Vorontsov

Is there a reason why the "online" file in the subdirectories for the CPUs
in /sys/devices/system isn't world-readable? I cannot imagine it to be
security relevant especially now that a getcpu() syscall can be used to
determine what CPUa thread runs on.The file is useful to correctly implement the sysconf() function to return
the number of online CPUs. In the presence of hotplug we currently cannot
provide this information. The patch below should to it.Signed-off-by: Ulrich Drepper

Revert 7e92b4fc345f5b6f57585fbe5ffdb0f24d7c9b26. It broke Sébastien Dugué's
machine and Jeff said (persuasively)This seems like it will break decades-long-working stuff, in favor of
breaking new ground in our favorite area, "trusting the BIOS."It's just not worth it for serial ports, IMO. Serial ports are something
that just shouldn't break at this late stage in the game. My new Intel
platform boxes don't even have serial ports, so I question the value of
messing with serial port probing even more... because... just wait a year,
and your box won't have a serial port either! :)I certainly don't object to the use of platform devices (or isa_driver),
but the probe change seems questionable. That's sorta analagous to
rewriting the floppy driver probe routine. Sure you could do it... but why
risk all that damage and go through debugging all over again?It seems clear from this report that we cannot, should not, trust BIOS for
something (a) so simple and (b) that has been working for over a decade.Much discussion ensued and we've decided to have another go at all of this.

A succesful downcall with a negative result (which indicates that the given
filesystem is not exported to the given user) should not return an error.Currently mountd is depending on stdio to write these downcalls. With some
versions of libc this appears to cause subsequent writes to attempt to write
all accumulated data (for which writes previously failed) along with any new
data. This can prevent the kernel from seeing responses to later downcalls.
Symptoms will be that nfsd fails to respond to certain requests.Signed-off-by: "J. Bruce Fields"

RFC 3530 says:
If the server uses an attribute to store the exclusive create verifier, it
will signify which attribute by setting the appropriate bit in the attribute
mask that is returned in the results.Linux uses the atime and mtime to store the verifier, but sends a zeroed out
bitmask back to the client. This patch makes sure that we set the correct
bits in the bitmask in this situation.Signed-off-by: Jeff Layton
