2015-04-23NFS: Reduce time spent holding the i_mutex during fallocate()Anna Schumaker
At the very least, we should not be taking the i_mutex until after checking if the server even supports ALLOCATE or DEALLOCATE, allowing v4.0 or v4.1 to exit without potentially waiting on a lock.

2015-04-23NFS: Don't zap caches on fallocate()Anna Schumaker
This patch adds a GETATTR to the end of ALLOCATE and DEALLOCATE operations so we can set the updated inode size and change attribute directly. DEALLOCATE will still need to release pagecache pages, so nfs42_proc_deallocate() now calls truncate_pagecache_range() before contacting the server.

2015-04-23i2c: Mark adapter devices with pm_runtime_no_callbacksCharles Keepax
Commit 523c5b89640e ("i2c: Remove support for legacy PM") removed the PM ops from the bus type, which causes the pm operations on the s3c2410 adapter device to fail (-ENOSUPP in rpm_callback). The adapter device doesn't get bound to a driver and as such can't have its own pm_runtime callbacks. Previously this was fine as the bus callbacks would have been used, but now this can cause devices which use PM runtime and are attached over I2C to fail to resume. This commit fixes this issue by marking all adapter devices with pm_runtime_no_callbacks, since they can't have any.

2015-04-23tipc: fix node refcount issueErik Hugne
When link statistics is dumped over netlink, we iterate over the list of peer nodes and append each links statistics to the netlink msg. In the case where the dump is resumed after filling up a nlmsg, the node refcnt is decremented without having been incremented previously which may cause the node reference to be freed. When this happens, the following info/stacktrace will be generated, followed by a crash or undefined behavior. We fix this by removing the erroneous call to tipc_node_put inside the loop that iterates over nodes. [ 384.312303] INFO: trying to register non-static key.

In the function tipc_sk_rcv(), the stack variable 'err' is only initialized to TIPC_ERR_NO_PORT for the first iteration over the link input queue. If a chain of messages are received from a link, failure to lookup the socket for any but the first message will cause the message to bounce back out on a random link.

2015-04-23tipc: fix topology server broken issueYing Xue
When a new topology server is launched in a new namespace, its listening socket is inserted into the "init ns" namespace's socket hash table rather than the one owned by the new namespace. Although the socket's namespace is forcedly changed to the new namespace later, the socket is still stored in the socket hash table of "init ns" namespace. When a client created in the new namespace connects its own topology server, the connection is failed as its server's socket could not be found from its own namespace's socket table. If __sock_create() instead of original sock_create_kern() is used to create the server's socket through specifying an expected namesapce, the socket will be inserted into the specified namespace's socket table, thereby avoiding to the topology server broken issue.

2015-04-23ibmveth: Fix off-by-one error in ibmveth_change_mtu()David Gibson
AFAIK the PAPR document which defines the virtual device interface used by the ibmveth driver doesn't specify a specific maximum MTU. So, in the ibmveth driver, the maximum allowed MTU is determined by the maximum allocated buffer size of 64k (corresponding to one page in the common case) minus the per-buffer overhead IBMVETH_BUFF_OH (which has value 22 for 14 bytes of ethernet header, plus 8 bytes for an opaque handle). This suggests a maximum allowable MTU of 65514 bytes, but in fact the driver only permits a maximum MTU of 65513. This is because there is a < instead of an <= in ibmveth_change_mtu(), which only permits an MTU which is strictly smaller than the buffer size, rather than allowing the buffer to be completely filled. This patch fixes the buglet. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Acked-by: Thomas Falcon <tlfalcon@linux.vnet.ibm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

In 02c958dd3 (net/macb: add TX multiqueue support for gem), the initialization of tx_head and tx_tail in macb_init_rings() was moved inside the loop that iterates over each element in the ring. Since tx_head and tx_tail only need to be assigned once, move them back out of the loop. Signed-off-by: Ben Shelton <ben.shelton@ni.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Pull audit fixes from Paul Moore: "Seven audit patches for v4.1, all bug fixes. The largest, and perhaps most significant commit helps resolve some memory pressure issues related to the inode cache and audit, there are also a few small commits which help resolve some timing issues with the audit log queue, and the rest fall into the always popular "code clean-up" category. In general, nothing really substantial, just a nice set of maintenance patches" * 'upstream' of git://git.infradead.org/users/pcmoore/audit: audit: Remove condition which always evaluates to false audit: reduce mmap_sem hold for mm->exe_file audit: consolidate handling of mm->exe_file audit: code clean up audit: don't reset working wait time accidentally with auditd audit: don't lose set wait time on first successful call to audit_log_start() audit: move the tree pruning to a dedicated thread
2015-04-22net: do not deplete pfmemalloc reserveEric Dumazet
build_skb() should look at the page pfmemalloc status. If set, this means page allocator allocated this page in the expectation it would help to free other pages. Networking stack can do that only if skb->pfmemalloc is also set. Also, we must refrain using high order pages from the pfmemalloc reserve, so __page_frag_refill() must also use __GFP_NOMEMALLOC for them. Under memory pressure, using order-0 pages is probably the best strategy. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Pull MTD updates from Brian Norris: "Common MTD: - Add Kconfig option for keeping both the 'master' and 'partition' MTDs registered as devices. This would really make a better default if we could do it over, as it allows a lot more flexibility in (1) determining the flash topology of the system from user-space and (2) adding temporary partitions at runtime (ioctl(BLKPG)). Unfortunately, this would possibly cause user-space breakage, as it will cause renumbering of the /dev/mtdX devices. We'll see if we can change this in the future, as there have already been a few people looking for this feature, and I know others have just been working around our current limitations instead of fixing them this way. - Along with the previous change, add some additional information to sysfs, so user-space can read the offset of each partition within its master device SPI NOR: - add new device tree compatible binding to represent the mostly-compatible class of SPI NOR flash which can be detected by their extended JEDEC ID bytes, cutting down the duplication of our ID tables - misc. new IDs Various other miscellaneous fixes and changes" * tag 'for-linus-20150422' of git://git.infradead.org/linux-mtd: (53 commits) mtd: spi-nor: Add support for Macronix mx25u6435f serial flash mtd: spi-nor: Add support for Winbond w25q64dw serial flash mtd: spi-nor: add support for the Winbond W25X05 flash mtd: spi-nor: support en25s64 device mtd: m25p80: bind to "nor-jedec" ID, for auto-detection Documentation: devicetree: m25p80: add "nor-jedec" binding mtd: Make MTD tests cancelable mtd: mtd_oobtest: Fix bitflip_limit usage in test case 3 mtd: docg3: remove invalid __exit annotations mtd: fsl_ifc_nand: use msecs_to_jiffies for time conversion mtd: atmel_nand: don't map the ROM table if no pmecc table offset in DT mtd: atmel_nand: add a definition for the oob reserved bytes mtd: part: Remove partition overlap checks mtd: part: Add sysfs variable for offset of partition mtd: part: Create the master device node when partitioned mtd: ts5500_flash: Fix typo in MODULE_DESCRIPTION in ts5500_flash.c mtd: denali: Disable sub-page writes in Denali NAND driver mtd: pxa3xx_nand: cleanup wait_for_completion handling mtd: nand: gpmi: Check for scan_bbt() error mtd: nand: gpmi: fixup return type of wait_for_completion_timeout ...
