This patch passes vif instead of wilc to wilc_send_config_pkt and it's related functions as well, because we need vif which is currently being used and vif has wilc as well. Change custom print with netdev_xxx format if there are custom print inside the functions we have changed. Function parameter of following functions are modified to vif. wilc_send_config_pkt wilc_wlan_cfg_set wilc_wlan_cfg_get wilc_wlan_cfg_commit wilc_wlan_txq_add_cfg_pkt wilc_wlan_txq_add_to_head Signed-off-by:

This patch moves the function wilc_send_config_pkt to wilc_wlan.c which handles transport since the purpose of the function is sending/getting of config information. coreconfiguator.[ch] will be rename with frame.[ch] later. The print codes of the function is removed also and they will be implemented with netdev_xx print format later. struct wid need to be moved to wilc_wlan_if.h which defines configure informations.

Station cannot connect to soft AP mode wilc when it is configured for WEP security. This patch fixes it by setting the key index within the key value and change the last else condition with DEFAULTKEY action case, and also do not use WILC_WFI_wep_default index to set wep key id. Signed-off-by:

roundup_pow_of_two return when called on a zero argument is undefined, so don't call it like that. This fixes a problem introduced by commit 322489d9 ("staging/lustre: Use roundup_pow_of_two() in LNetEQAlloc()") since 0 is a valid count parameter for LNetEQAlloc. Also manifesting itself as an annoying kernel warning: LNet: 3486:0:(lib-eq.c:85:LNetEQAlloc()) EQ callback is guaranteed to get every event, do you still want to set eqcount 1 for polling event which will have locking overhead?

It turns out that unlike procfs, debugfs does not really enforce permissions for root (similar to regular filesystems), so we need to ensure we are not providing ->write() method to read-only files and ->read() method for write-only files at registration. This fixes a couple of crashes on unexpected access. Signed-off-by:

Pull ARM SoC fixes from Olof Johansson: "The first real batch of fixes for this release cycle, so there are a few more than usual. Most of these are fixes and tweaks to board support (DT bugfixes, etc). I've also picked up a couple of small cleanups that seemed innocent enough that there was little reason to wait (const/ __initconst and Kconfig deps). Quite a bit of the changes on OMAP were due to fixes to no longer write to rodata from assembly when ARM_KERNMEM_PERMS was enabled, but there were also other fixes. Kirkwood had a bunch of gpio fixes for some boards. OMAP had RTC fixes on OMAP5, and Nomadik had changes to MMC parameters in DT.

ethtool_ops has attributes in sub struct ethtool_coalesce that correspond to the parameters intagg_delay and dynamic_intagg. It is preferable to set these properties with ethtool rather than module_param, so create these attributes in adapter and set them using ethtool_coalesce's rx_coalesce_usecs and rx_use_adaptive_coalesce.

In the current implementation of the EPOLLEXCLUSIVE flag (added for 4.5-rc1), if epoll waiters create different POLL* sets and register them as exclusive against the same target fd, the current implementation will stop waking any further waiters once it finds the first idle waiter. This means that waiters could miss wakeups in certain cases. For example, when we wake up a pipe for reading we do: wake_up_interruptible_sync_poll(&pipe->wait, POLLIN | POLLRDNORM); So if one epoll set or epfd is added to pipe p with POLLIN and a second set epfd2 is added to pipe p with POLLRDNORM, only epfd may receive the wakeup since the current implementation will stop after it finds any intersection of events with a waiter that is blocked in epoll_wait(). We could potentially address this by requiring all epoll waiters that are added to p be required to pass the same set of POLL* events. IE the first EPOLL_CTL_ADD that passes EPOLLEXCLUSIVE establishes the set POLL* flags to be used by any other epfds that are added as EPOLLEXCLUSIVE. However, I think it might be somewhat confusing interface as we would have to reference count the number of users for that set, and so userspace would have to keep track of that count, or we would need a more involved interface. It also adds some shared state that we'd have store somewhere. I don't think anybody will want to bloat __wait_queue_head for this. I think what we could do instead, is to simply restrict EPOLLEXCLUSIVE such that it can only be specified with EPOLLIN and/or EPOLLOUT. So that way if the wakeup includes 'POLLIN' and not 'POLLOUT', we can stop once we hit the first idle waiter that specifies the EPOLLIN bit, since any remaining waiters that only have 'POLLOUT' set wouldn't need to be woken. Likewise, we can do the same thing if 'POLLOUT' is in the wakeup bit set and not 'POLLIN'. If both 'POLLOUT' and 'POLLIN' are set in the wake bit set (there is at least one example of this I saw in fs/pipe.c), then we just wake the entire exclusive list. Having both 'POLLOUT' and 'POLLIN' both set should not be on any performance critical path, so I think that's ok (in fs/pipe.c its in pipe_release()). We also continue to include EPOLLERR and EPOLLHUP by default in any exclusive set. Thus, the user can specify EPOLLERR and/or EPOLLHUP but is not required to do so. Since epoll waiters may be interested in other events as well besides EPOLLIN, EPOLLOUT, EPOLLERR and EPOLLHUP, these can still be added by doing a 'dup' call on the target fd and adding that as one normally would with EPOLL_CTL_ADD. Since I think that the POLLIN and POLLOUT events are what we are interest in balancing, I think that the 'dup' thing could perhaps be added to only one of the waiter threads. However, I think that EPOLLIN, EPOLLOUT, EPOLLERR and EPOLLHUP should be sufficient for the majority of use-cases. Since EPOLLEXCLUSIVE is intended to be used with a target fd shared among multiple epfds, where between 1 and n of the epfds may receive an event, it does not satisfy the semantics of EPOLLONESHOT where only 1 epfd would get an event. Thus, it is not allowed to be specified in conjunction with EPOLLEXCLUSIVE. EPOLL_CTL_MOD is also not allowed if the fd was previously added as EPOLLEXCLUSIVE. It seems with the limited number of flags to not be as interesting, but this could be relaxed at some further point. Signed-off-by:

Helper radix_tree_iter_retry() resets next_index to the current index. In following radix_tree_next_slot current chunk size becomes zero. This isn't checked and it tries to dereference null pointer in slot. Tagged iterator is fine because retry happens only at slot 0 where tag bitmask in iter->tags is filled with single bit.

Commit ea8f8fc8 ("MAINTAINERS: add linux-api for review of API/ABI changes") added file triggers for various paths that likely indicated API/ABI changes. However, catching all changes in Documentation/ABI/ and include/uapi/ produces a large volume of mail to linux-api, rather than only API/ABI changes. Drop those two entries, but leave include/linux/syscalls.h and kernel/sys_ni.c to catch syscall-related changes. [josh@joshtriplett.org: redid changelog] Signed-off-by:
