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.

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:

In current 2.6.23-rc1+git, make bootimage gives the following warning while compiling arch/alpha/boot/main.c. The patch below fixes the warning by casting callback argument explicitly to void*.

Revert 7e92b4fc. 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:

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.
