2010-10-31locks: let the caller free file_lock on ->setlease failureChristoph Hellwig
The caller allocated it, the caller should free it. The only issue so far is that we could change the flp pointer even on an error return if the fl_change callback failed. But we can simply move the flp assignment after the fl_change invocation, as the callers don't care about the flp return value if the setlease call failed.

Commit ffe8018c3424 ("initramfs: fix initramfs size calculation") broke 32-bit big-endian arches like (on ARAnyM): VFS: Cannot open root device "hda1" or unknown-block(3,1) Please append a correct "root=" boot option; here are the available partitions: fe80 1059408 nfhd8 (driver?) fe81 921600 nfhd8p1 00000000-0000-0000-0000-000000000nfhd8p1 fe82 137807 nfhd8p2 00000000-0000-0000-0000-000000000nfhd8p2 0200 3280 fd0 (driver?) 0201 3280 fd1 (driver?) 0300 1059408 hda driver: ide-gd 0301 921600 hda1 00000000-0000-0000-0000-000000000hda1 0302 137807 hda2 00000000-0000-0000-0000-000000000hda2 Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(3,1) As pointed out by Kerstin Jonsson <kerstin.jonsson@ericsson.com>, this is due to CONFIG_32BIT not being defined, so the initramfs size field is done as a 64-bit quad. 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.

2010-10-30nfsd4: initialize delegation pointer to leaseJ. Bruce Fields
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.

2010-10-30RDS: Let rds_message_alloc_sgs() return NULLAndy Grover
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>
2010-10-30RDS: Copy rds_iovecs into kernel memory instead of rereading from userspaceAndy Grover
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.

2010-10-30net: fix rds_iovec page count overflowLinus Torvalds
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.

2010-10-30Btrfs: deal with errors from updating the tree logChris Mason
During unlink we remove any references to the inode from the tree log. It can return -ENOENT and other errors, and this changes the unlink code to deal with it. Signed-off-by: Chris Mason <chris.mason@oracle.com>

2010-10-30x86: Check irq_remapped instead of remapping_enabled in destroy_irq()Yinghai Lu
Russ Anderson reported: | There is a regression that is causing a NULL pointer dereference | in free_irte when shutting down xpc. git bisect narrowed it down | to git commit d585d06(intr_remap: Simplify the code further), which | changed free_irte(). Reverse applying the patch fixes the problem. We need to use irq_remapped() for each irq instead of checking only intr_remapping_enabled as there might be non remapped irqs even when remapping is enabled.

I was doing some namespace checks and found some simple stuff in audit that could be cleaned up. Make some functions static, and put const on make_reply payload arg. Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2010-10-30Audit: add support to match lsm labels on user audit messagesMiloslav Trmac
Add support for matching by security label (e.g. SELinux context) of the sender of an user-space audit record. The audit filter code already allows user space to configure such filters, but they were ignored during evaluation. This patch implements evaluation of these filters. For example, after application of this patch, PAM authentication logs caused by cron can be disabled using auditctl -a user,never -F subj_type=crond_t Signed-off-by: Miloslav Trmac <mitr@redhat.com> Acked-by: Eric Paris <eparis@redhat.com> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
