The kernel has no concept of capabilities with respect to inodes; inodes exist independently of namespaces. For example, inode_capable(inode, CAP_LINUX_IMMUTABLE) would be nonsense. This patch changes inode_capable to check for uid and gid mappings and renames it to capable_wrt_inode_uidgid, which should make it more obvious what it does. Fixes CVE-2014-4014.

Currently, the DRC cache pruner will stop scanning the list when it hits an entry that is RC_INPROG. It's possible however for a call to take a *very* long time. In that case, we don't want it to block other entries from being pruned if they are expired or we need to trim the cache to get back under the limit. Fix the DRC cache pruner to just ignore RC_INPROG entries. Signed-off-by: NJeff Layton <jlayton@primarydata.com> Signed-off-by: NJ. Bruce Fields <bfields@redhat.com>

The rpc code makes available to the NFS server an array of pages to encod into. The server represents its reply as an xdr buf, with the head pointing into the first page in that array, the pages ** array starting just after that, and the tail (if any) sharing any leftover space in the page used by the head. While encoding, we use xdr_stream->page_ptr to keep track of which page we're currently using. Currently we set xdr_stream->page_ptr to buf->pages, which makes the head a weird exception to the rule that page_ptr always points to the page we're currently encoding into. So, instead set it to buf->pages - 1 (the page actually containing the head), and remove the need for a little unintuitive logic in xdr_get_next_encode_buffer() and xdr_truncate_encode.

Commit 788257d6 ("ufs: remove the BKL") replaced BKL with mutex protection using functions lock_ufs, unlock_ufs and struct mutex 'mutex' in sb_info. Commit b6963327 ("ufs: drop lock/unlock super") removed lock/unlock super and added struct mutex 's_lock' in sb_info. Those 2 mutexes are generally locked/unlocked at the same time except in allocation (balloc, ialloc). This patch merges the 2 mutexes and propagates first commit solution. It also adds mutex destruction before kfree during ufs_fill_super failure and ufs_put_super.

jffs2_garbage_collect_thread() does disallow_signal(SIGHUP) around jffs2_garbage_collect_pass() and the comment says "We don't want SIGHUP to interrupt us". But disallow_signal() can't ensure that jffs2_garbage_collect_pass() won't be interrupted by SIGHUP, the problem is that SIGHUP can be already pending when disallow_signal() is called, and in this case any interruptible sleep won't block. Note: this is in fact because disallow_signal() is buggy and should be fixed, see the next changes. But there is another reason why disallow_signal() is wrong: SIG_IGN set by disallow_signal() silently discards any SIGHUP which can be sent before the next allow_signal(SIGHUP). Change this code to use sigprocmask(SIG_UNBLOCK/SIG_BLOCK, SIGHUP). This even matches the old (and wrong) semantics allow/disallow had when this logic was written.

Initializations like 'char *foo = "bar"' will create two variables: a static string and a pointer (foo) to that static string.

Add structure for parsed BPB information, struct fat_bios_param_block, and move all of the deserialization and validation logic from fat_fill_super() into fat_read_bpb(). Add a 'dos1xfloppy' mount option to infer DOS 2.x BIOS Parameter Block defaults from block device geometry for ancient floppies and floppy images, as a fall-back from the default BPB parsing logic. When fat_read_bpb() finds an invalid FAT filesystem and dos1xfloppy is set, fall back to fat_read_static_bpb(). fat_read_static_bpb() validates that the entire BPB is zero, and that the floppy has a DOS-style 8086 code bootstrapping header. Then it fills in default BPB values from media size and a table.[0] Media size is assumed to be static for archaic FAT volumes. See also: [1]. Fixes kernel.org bug #42617.

Commit a99b7069 ("hfsplus: Fix undefined __divdi3 in hfsplus_init_header_node()") introduced do_div() to xattr.c and the warning below too. As Geert remarked: "tmp" is "loff_t" which is "__kernel_loff_t", which is "long long", i.e. signed, while include/asm-generic/div64.h compares its type with "uint64_t". As inode sizes are positive, it should be safe to change the type of "tmp" to "u64".
