2008-03-06[IA64] update efi region debugging to use MB, GB and TB as well as KBSimon Horman
When EFI_DEBUG is defined to a non-zero value in arch/ia64/kernel/efi.c, the efi memory regions are displayed. This patch enhances the display code in a few ways: 1. Use TB, GB and MB as well as KB as units. Although this introduces rounding errors (KB doesn't as size is always a multiple of 4Kb), it does make things a lot more readable. Also as the range is also shown, it is possible to note the exact size if it is important. In my experience, the size field is mostly useful for getting a general idea of the size of a region. On the rx2620 that I use, there actually is an 8TB region (though not backed by physical memory, and 8TB really is a lot more readable than 8589934592KB. 2. pad the size field with leading spaces to further improve readability ... ...

2008-03-06[CRYPTO] xcbc: Fix crash with IPsecJoy Latten
When using aes-xcbc-mac for authentication in IPsec, the kernel crashes. It seems this algorithm doesn't account for the space IPsec may make in scatterlist for authtag. Thus when crypto_xcbc_digest_update2() gets called, nbytes may be less than sg[i].length. Since nbytes is an unsigned number, it wraps at the end of the loop allowing us to go back into loop and causing crash in memcpy. I used update function in digest.c to model this fix.

wakeups Idle state is not being detected properly by the xfsaild push code. The current idle state is detected by an empty list which may never happen with mostly idle filesystem or one using lazy superblock counters. A single dirty item in the list that exists beyond the push target can result repeated looping attempting to push up to the target because it fails to check if the push target has been acheived or not. Fix by considering a dirty list with everything past the target as an idle state and set the timeout appropriately.

2008-03-06NFS: use new LSM interfaces to explicitly set mount optionsEric Paris
NFS and SELinux worked together previously because SELinux had NFS specific knowledge built in. This design was approved by both groups back in 2004 but the recent NFS changes to use nfs_parsed_mount_data and the usage of nfs_clone_mount_data showed this to be a poor fragile solution. This patch fixes the NFS functionality regression by making use of the new LSM interfaces to allow an FS to explicitly set its own mount options. The explicit setting of mount options is done in the nfs get_sb functions which are called before the generic vfs hooks try to set mount options for filesystems which use text mount data. This does not currently support NFSv4 as that functionality did not exist in previous kernels and thus there is no regression. I will be adding the needed code, which I believe to be the exact same as the v3 code, in nfs4_get_sb for 2.6.26.

2008-03-06LSM/SELinux: Interfaces to allow FS to control mount optionsEric Paris
Introduce new LSM interfaces to allow an FS to deal with their own mount options. This includes a new string parsing function exported from the LSM that an FS can use to get a security data blob and a new security data blob. This is particularly useful for an FS which uses binary mount data, like NFS, which does not pass strings into the vfs to be handled by the loaded LSM. Also fix a BUG() in both SELinux and SMACK when dealing with binary mount data. If the binary mount data is less than one page the copy_page() in security_sb_copy_data() can cause an illegal page fault and boom. Remove all NFSisms from the SELinux code since they were broken by past NFS changes.

Using the /proc/dasd/devices interface leaves the reference counter of alias devices in an inconsistent state. A process that tries to set such a device offline afterwards will hang. The dasd_devices_show function returns immediately for alias devices and this code path was missing a dasd_put_device call.

2008-03-05[S390] dasd: let dasd erp matching recognize alias recoveryStefan Weinhuber
When a request fails that was started on an alias device then the first recovery step is to retry it on the base device. If the recovery request fails again with the same symptoms, the next step should not be a simple retry, but should be a proper recovery based on sense data, etc. To do so, the dasd recovery functions need to recognize the alias recovery step in the erp chain by comparing the start devices.

2008-03-05[S390] Get rid of memcpy gcc warning workaround.Heiko Carstens
Compile smp.o with -Wno-nonnull so gcc stops warning about memcpy being used with a null parameter. Also remove the workaround code and use a char * cast instead of a void * cast to do computations.

2008-03-05[S390] idle: Fix machine check handling in idle loop.Heiko Carstens
If a machine check handling is pending when the idle loop is entered default_idle will be left with timer ticks and virtual timer disabled. Fix this by "calling" the idle_chain. Also a BUG_ON(!in_interrupt) in start_hz_timer must be removed since the function now gets called from non interrupt context as well.
