2014-10-07nfsd: fix potential lease memory leak in nfs4_setleaseJeff Layton
It's unlikely to ever occur, but if there were already a lease set on the file then we could end up getting back a different pointer on a successful setlease attempt than the one we allocated. If that happens, the one we allocated could leak. In practice, I don't think this will happen due to the fact that we only try to set up the lease once per nfs4_file, but this error handling is a bit more correct given the current lease API. Cc: J.

2014-10-07locks: close potential race in lease_get_mtimeJeff Layton
lease_get_mtime is called without the i_lock held, so there's no guarantee about the stability of the list. Between the time when we assign "flock" and then dereference it to check whether it's a lease and for write, the lease could be freed. Ensure that that doesn't occur by taking the i_lock before trying to check the lease. Cc: J.

Merge ipmi patches from Corey Minyard: "These have been in linux-next for a while, ready for 3.18" * emailed patches from Corey Minyard <minyard@acm.org>: ipmi: Clear drvdata when interface is removed ipmi: work around gcc-4.9 build warning ipmi/of: Don't use unavailable interfaces ipmi: Clean up the error handling for channel config errors
2014-10-07ipmi: Clear drvdata when interface is removedTakao Indoh
This patch fixes a bug on hotmod removing. After ipmi interface is removed using hotmod, kernel panic occurs when rmmod impi_si. For example, try this: # echo "remove,"`cat /proc/ipmi/0/params` > \ /sys/module/ipmi_si/parameters/hotmod # rmmod ipmi_si Then, rmmod fails with the following messages. ------------[ cut here ]------------ WARNING: CPU: 12 PID: 10819 at /mnt/repos/linux/lib/list_debug.c:53 __list_del_entry+0x63/0xd0() CPU: 12 PID: 10819 Comm: rmmod Not tainted 3.17.0-rc1 #19 Hardware name: FUJITSU-SV PRIMERGY BX920 S2/D3030, BIOS 080015 Rev.3D81.3030 02/10/2012 Call Trace: dump_stack+0x45/0x56 warn_slowpath_common+0x7d/0xa0 warn_slowpath_fmt+0x4c/0x50 __list_del_entry+0x63/0xd0 list_del+0xd/0x30 cleanup_one_si+0x2a/0x230 [ipmi_si] ipmi_pnp_remove+0x15/0x20 [ipmi_si] pnp_device_remove+0x24/0x40 __device_release_driver+0x7f/0xf0 driver_detach+0xb0/0xc0 bus_remove_driver+0x55/0xd0 driver_unregister+0x2c/0x50 pnp_unregister_driver+0x12/0x20 cleanup_ipmi_si+0xbc/0xf0 [ipmi_si] SyS_delete_module+0x132/0x1c0 system_call_fastpath+0x16/0x1b ---[ end trace 70b4377268f85c23 ]--- list_del in cleanup_one_si() fails because the smi_info is already removed when hotmod removing. When ipmi interface is removed by hotmod, smi_info is removed by cleanup_one_si(), but is is still set in drvdata. Therefore when rmmod ipmi_si, ipmi_pnp_remove tries to remove it again and fails. By this patch, a pointer to smi_info in drvdata is cleared when hotmod removing so that it will be not accessed when rmmod. changelog: v2: - Clear drvdata in cleanup_one_si - Change subject v1: https://lkml.org/lkml/2014/9/8/741 Signed-off-by: Takao Indoh <indou.takao@jp.fujitsu.com> Signed-off-by: Corey Minyard <cminyard@mvista.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2014-10-07ipmi: work around gcc-4.9 build warningArnd Bergmann
Building ipmi on arm with gcc-4.9 results in this warning for an allmodconfig build: drivers/char/ipmi/ipmi_si_intf.c: In function 'ipmi_thread': include/linux/time.h:28:5: warning: 'busy_until.tv_sec' may be used uninitialized in this function [-Wmaybe-uninitialized] if (lhs->tv_sec > rhs->tv_sec) ^ drivers/char/ipmi/ipmi_si_intf.c:1007:18: note: 'busy_until.tv_sec' was declared here struct timespec busy_until; ^ The warning is bogus and this case can not occur. Apparently this is a false positive resulting from gcc getting a little smarter about tracking assignments but not smart enough. Marking the ipmi_thread_busy_wait function as inline gives the gcc optimization logic enough information to figure out for itself that the case cannot happen, which gets rid of the warning without adding any fake initialization.

2014-10-07net: better IFF_XMIT_DST_RELEASE supportEric Dumazet
Testing xmit_more support with netperf and connected UDP sockets, I found strange dst refcount false sharing. Current handling of IFF_XMIT_DST_RELEASE is not optimal. Dropping dst in validate_xmit_skb() is certainly too late in case packet was queued by cpu X but dequeued by cpu Y The logical point to take care of drop/force is in __dev_queue_xmit() before even taking qdisc lock. As Julian Anastasov pointed out, need for skb_dst() might come from some packet schedulers or classifiers. This patch adds new helper to cleanly express needs of various drivers or qdiscs/classifiers. Drivers that need skb_dst() in their ndo_start_xmit() should call following helper in their setup instead of the prior : dev->priv_flags &= ~IFF_XMIT_DST_RELEASE; -> netif_keep_dst(dev); Instead of using a single bit, we use two bits, one being eventually rebuilt in bonding/team drivers. The other one, is permanent and blocks IFF_XMIT_DST_RELEASE being rebuilt in bonding/team. Eventually, we could add something smarter later.

2014-10-07net/mlx4_en: remove NETDEV_TX_BUSYEric Dumazet
Drivers should avoid NETDEV_TX_BUSY as much as possible. They should stop the tx queue before qdisc even tries to push another packet, to avoid requeues. For a driver supporting skb->xmit_more, this is likely to be a prereq anyway, otherwise we could have a tx deadlock : We need to force a doorbell if TX ring is full.
