2016-03-17mm: introduce page reference manipulation functionsJoonsoo Kim1-1/+1
The success of CMA allocation largely depends on the success of migration and key factor of it is page reference count. Until now, page reference is manipulated by direct calling atomic functions so we cannot follow up who and where manipulate it. Then, it is hard to find actual reason of CMA allocation failure. CMA allocation should be guaranteed to succeed so finding offending place is really important. In this patch, call sites where page reference is manipulated are converted to introduced wrapper function. This is preparation step to add tracepoint to each page reference manipulation function. With this facility, we can easily find reason of CMA allocation failure. There is no functional change in this patch. In addition, this patch also converts reference read sites. It will help a second step that renames page._count to something else and prevents later attempt to direct access to it (Suggested by Andrew).

2015-02-28niu: fix error handling in niu_class_to_ethflow()Dan Carpenter1-4/+2
There is a discrepancy here because the niu_class_to_ethflow() returns zero on failure and one on success but the caller expected zero on success and negative on failure. The problem means that we allow the user to pass classes and flow_types which we don't want. I've looked at it a bit and I don't see it as a very serious bug.

2012-10-02Merge branch 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wqLinus Torvalds1-1/+1
Pull workqueue changes from Tejun Heo: "This is workqueue updates for v3.7-rc1. A lot of activities this round including considerable API and behavior cleanups. * delayed_work combines a timer and a work item. The handling of the timer part has always been a bit clunky leading to confusing cancelation API with weird corner-case behaviors. delayed_work is updated to use new IRQ safe timer and cancelation now works as expected. * Another deficiency of delayed_work was lack of the counterpart of mod_timer() which led to cancel+queue combinations or open-coded timer+work usages. mod_delayed_work[_on]() are added. These two delayed_work changes make delayed_work provide interface and behave like timer which is executed with process context. * A work item could be executed concurrently on multiple CPUs, which is rather unintuitive and made flush_work() behavior confusing and half-broken under certain circumstances. This problem doesn't exist for non-reentrant workqueues. While non-reentrancy check isn't free, the overhead is incurred only when a work item bounces across different CPUs and even in simulated pathological scenario the overhead isn't too high. All workqueues are made non-reentrant. This removes the distinction between flush_[delayed_]work() and flush_[delayed_]_work_sync(). The former is now as strong as the latter and the specified work item is guaranteed to have finished execution of any previous queueing on return. * In addition to the various bug fixes, Lai redid and simplified CPU hotplug handling significantly. * Joonsoo introduced system_highpri_wq and used it during CPU hotplug. There are two merge commits - one to pull in IRQ safe timer from tip/timers/core and the other to pull in CPU hotplug fixes from wq/for-3.6-fixes as Lai's hotplug restructuring depended on them." Fixed a number of trivial conflicts, but the more interesting conflicts were silent ones where the deprecated interfaces had been used by new code in the merge window, and thus didn't cause any real data conflicts.

2012-05-03net/niu: remove one superfluous dma mask checkSebastian Andrzej Siewior1-1/+1
The idea here seems to be to get a 44bit DMA mask working and if this fails it should fallback to a 32bit DMA mask. The dma_mask variable is assigned once to 44bit and never updated. pci_set_dma_mask() and pci_set_consistent_dma_mask() are both implemented as functions so there is no evil macro which might update dma_mask. Looking at the assembly, I see a call to dma_set_mask() followed by dma_supported() and then a jump passed the second dma_set_mask(). The only way to get to second dma_set_mask() call is by an error code in the first one. So I hereby remove the check since it looks superfluous. Please ignore the path if there is black magic involved. Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: David S. Miller <davem@davemloft.net>

2011-10-19net: add skb frag size accessorsEric Dumazet1-3/+3
To ease skb->truesize sanitization, its better to be able to localize all references to skb frags size. Define accessors : skb_frag_size() to fetch frag size, and skb_frag_size_{set|add|sub}() to manipulate it. Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S.

2011-10-13niu: fix skb truesize underestimationEric Dumazet1-8/+4
Add a 'truesize' argument to niu_rx_skb_append(), filled with rcr_size by the caller to properly account frag sizes in skb->truesize Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2011-09-16ethtool: Update ethtool_rxnfc::rule_cnt on return from ETHTOOL_GRXCLSRLALLBen Hutchings1-0/+2
A user-space process must use ETHTOOL_GRXCLSRLCNT to find the number of classification rules, then allocate a buffer of the right size, then use ETHTOOL_GRXCLSRLALL to fill the buffer. If some other process inserts or deletes a rule between those two operations, the user buffer might turn out to be the wrong size. If it's too small, the return value will be -EMSGSIZE. But if it's too large, there is no indication of this. Fix this by updating the rule_cnt field on return. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

2011-09-16ethtool: Clean up definitions of rule location arrays in RX NFCBen Hutchings1-2/+2
Correct the description of ethtool_rxnfc::rule_locs; it is an array of currently used locations, not all possible valid locations. Add note that drivers must not use ethtool_rxnfc::rule_locs. The rule_locs argument to ethtool_ops::get_rxnfc is either NULL or a pointer to an array of u32, so change the parameter type accordingly.

2011-08-17net: introduce IFF_UNICAST_FLT private flagJiri Pirko1-1/+4
Use IFF_UNICAST_FTL to find out if driver handles unicast address filtering. In case it does not, promisc mode is entered. Patch also fixes following drivers: stmmac, niu: support uc filtering and yet it propagated ndo_set_multicast_list bna, benet, pxa168_eth, ks8851, ks8851_mll, ksz884x : has set ndo_set_rx_mode but do not support uc filtering Signed-off-by: Jiri Pirko <jpirko@redhat.com> Signed-off-by: David S.

2011-08-11cassini/niu/sun*: Move the Sun driversJeff Kirsher1-0/+10263
Moves the Sun drivers into drivers/net/ethernet/sun/ and make the necessary Kconfig and Makefile changes. Oliver Hartkopp <socketcan@hartkopp.net> suggested removing the sun* prefix on the driver names. This type of change I will leave up to the driver maintainers.
