2010-11-11x86, cpu: Clear XD_DISABLED flag on Intel to regain NXKees Cook1-8/+40
Intel CPUs have an additional MSR bit to indicate if the BIOS was configured to disable the NX cpu feature. This bit was traditionally used for operating systems that did not understand how to handle the NX bit. Since Linux understands this, this BIOS flag should be ignored by default. In a review[1] of reported hardware being used by Ubuntu bug reporters, almost 10% of systems had an incorrectly configured BIOS, leaving their systems unable to use the NX features of their CPU. This change will clear the MSR_IA32_MISC_ENABLE_XD_DISABLE bit so that NX cannot be inappropriately controlled by the BIOS on Intel CPUs. If, under very strange hardware configurations, NX actually needs to be disabled, "noexec=off" can be used to restore the prior behavior.

On little-endian (like x86) this doesn matter, but on a big-endian machine the 32-bit reads will see the (zero) high bits. Only mips, s390, and score set CONFIG_32BIT for 32-bit builds, so fix it for all other 32-bit arches by inverting the logic and testing for CONFIG_64BIT, which should be defined on all 64-bit arches.

2010-10-31nfsd4: initialize delegation pointer to leaseJ. Bruce Fields1-17/+2
The NFSv4 server was initializing the dp->dl_flock pointer by the somewhat ridiculous method of a locks_copy_lock callback. Now that setlease uses the passed-in lock instead of doing a copy, dl_flock no longer gets set, resulting in the lock leaking on delegation release, and later possible hangs (among other problems). So, initialize dl_flock and get rid of the callback. Signed-off-by: J.

2010-10-31RDS: Let rds_message_alloc_sgs() return NULLAndy Grover3-0/+17
Even with the previous fix, we still are reading the iovecs once to determine SGs needed, and then again later on. Preallocating space for sg lists as part of rds_message seemed like a good idea but it might be better to not do this. While working to redo that code, this patch attempts to protect against userspace rewriting the rds_iovec array between the first and second accesses. The consequences of this would be either a too-small or too-large sg list array. Too large is not an issue. This patch changes all callers of message_alloc_sgs to handle running out of preallocated sgs, and fail gracefully. Signed-off-by: Andy Grover <andy.grover@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-10-31RDS: Copy rds_iovecs into kernel memory instead of rereading from userspaceAndy Grover1-39/+65
Change rds_rdma_pages to take a passed-in rds_iovec array instead of doing copy_from_user itself. Change rds_cmsg_rdma_args to copy rds_iovec array once only. This eliminates the possibility of userspace changing it after our sanity checks. Implement stack-based storage for small numbers of iovecs, based on net/socket.c, to save an alloc in the extremely common case. Although this patch reduces iovec copies in cmsg_rdma_args to 1, we still do another one in rds_rdma_extra_size. Getting rid of that one will be trickier, so it'll be a separate patch.

2010-10-31net: fix rds_iovec page count overflowLinus Torvalds1-0/+7
As reported by Thomas Pollet, the rdma page counting can overflow. We get the rdma sizes in 64-bit unsigned entities, but then limit it to UINT_MAX bytes and shift them down to pages (so with a possible "+1" for an unaligned address). So each individual page count fits comfortably in an 'unsigned int' (not even close to overflowing into signed), but as they are added up, they might end up resulting in a signed return value. Which would be wrong. Catch the case of tot_pages turning negative, and return the appropriate error code.

2010-10-30fs-writeback.c: unify some common codeLinus Torvalds1-10/+13
The btrfs merge looks like hell, because it changes fs-writeback.c, and the crazy code has this repeated "estimate number of dirty pages" counting that involves three different helper functions. And it's done in two different places. Just unify that whole calculation as a "get_nr_dirty_pages()" helper function, and the merge result will look half-way decent.
