2017-07-14ubifs: Don't leak kernel memory to the MTDRichard Weinberger1-5/+5
When UBIFS prepares data structures which will be written to the MTD it ensues that their lengths are multiple of 8. Since it uses kmalloc() the padded bytes are left uninitialized and we leak a few bytes of kernel memory to the MTD. To make sure that all bytes are initialized, let's switch to kzalloc(). Kzalloc() is fine in this case because the buffers are not huge and in the IO path the performance bottleneck is anyway the MTD.

2017-07-14ubifs: Change gfp flags in page allocation for bulk readHyunchul Lee1-2/+2
In low memory situations, page allocations for bulk read can kill applications for reclaiming memory, and print an failure message when allocations are failed. Because bulk read is just an optimization, we don't have to do these and can stop page allocations. Though this siutation happens rarely, add __GFP_NORETRY to prevent from excessive memory reclaim and killing applications, and __GFP_WARN to suppress this failure message. For this, Use readahead_gfp_mask for gfp flags when allocating pages. Signed-off-by: Hyunchul Lee <cheol.lee@lge.com> Signed-off-by: Richard Weinberger <richard@nod.at>
2017-07-14ubifs: Fix oops when remounting with no_bulk_read.karam.lee1-0/+2
When remounting with the no_bulk_read option, there is a problem accessing the "bulk_read buffer(bu.buf)" which has already been freed. If the bulk_read option is enabled, ubifs_tnc_bulk_read uses the pre-allocated bu.buf. While bu.buf is being used by ubifs_tnc_bulk_read, remounting with no_bulk_read frees bu.buf. So I added code to check the use of "bu.buf" to avoid this situation. ------ I tested as follows(kernel v3.18) : Use the script to repeat "no_bulk_read <-> bulk_read" remount.sh #!/bin/sh while true do; mount -o remount,no_bulk_read ${MOUNT_POINT}; sleep 1; mount -o remount,bulk_read ${MOUNT_POINT}; sleep 1; done Perform read operation cat ${MOUNT_POINT}/* > /dev/null The problem is reproduced immediately.

2017-07-14ubifs: Fail commit if TNC is obviously inconsistentRichard Weinberger1-0/+4
A reference to LEB 0 or with length 0 in the TNC is never correct and could be caused by a memory corruption. Don't write such a bad index node to the MTD. Instead fail the commit which will turn UBIFS into read-only mode. This is less painful than having the bad reference on the MTD from where UBFIS has no chance to recover.

2017-07-14ubifs: allow userspace to map mounts to volumesRabin Vincent1-0/+7
There currently appears to be no way for userspace to find out the underlying volume number for a mounted ubifs file system, since ubifs uses anonymous block devices. The volume name is present in /proc/mounts but UBI volumes can be renamed after the volume has been mounted. To remedy this, show the UBI number and UBI volume number as part of the options visible under /proc/mounts. Also, accept and ignore the ubi= vol= options if they are used mounting (patch from Richard Weinberger). # mount -t ubifs ubi:baz x # mount ubi:baz on /root/x type ubifs (rw,relatime,ubi=0,vol=2) # ubirename /dev/ubi0 baz bazz # mount ubi:baz on /root/x type ubifs (rw,relatime,ubi=0,vol=2) # ubinfo -d 0 -n 2 Volume ID: 2 (on ubi0) Type: dynamic Alignment: 1 Size: 67 LEBs (1063424 bytes, 1.0 MiB) State: OK Name: bazz Character device major/minor: 254:3 Signed-off-by: Rabin Vincent <rabinv@axis.com> Signed-off-by: Richard Weinberger <richard@nod.at>

2017-07-14ubifs: Correctly evict xattr inodesRichard Weinberger3-0/+25
UBIFS handles extended attributes just like files, as consequence of that, they also have inodes. Therefore UBIFS does all the inode machinery also for xattrs. Since new inodes have i_nlink of 1, a file or xattr inode will be evicted if i_nlink goes down to 0 after an unlink. UBIFS assumes this model also for xattrs, which is not correct. One can create a file "foo" with xattr "user.test". By reading "user.test" an inode will be created, and by deleting "user.test" it will get evicted later. The assumption breaks if the file "foo", which hosts the xattrs, will be removed. VFS nor UBIFS does not remove each xattr via ubifs_xattr_remove(), it just removes the host inode from the TNC and all underlying xattr nodes too and the inode will remain in the cache and wastes memory. To solve this problem, remove xattr inodes from the VFS inode cache in ubifs_xattr_remove() to make sure that they get evicted.

The cpu_cooling driver is designed to use CPU frequency scaling to avoid high thermal states for a platform. But it wasn't glued really well with cpufreq core. For example clipped-cpus is copied from the policy structure and its much better to use the policy->cpus (or related_cpus) fields directly as they may have got updated. Not that things were broken before this series, but they can be optimized a bit more.
