2018-06-12treewide: kmalloc() -> kmalloc_array()Kees Cook1-1/+1
The kmalloc() function has a 2-factor argument form, kmalloc_array(). This patch replaces cases of: kmalloc(a * b, gfp) with: kmalloc_array(a * b, gfp) as well as handling cases of: kmalloc(a * b * c, gfp) with: kmalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kmalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kmalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The tools/ directory was manually excluded, since it has its own implementation of kmalloc(). The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kmalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kmalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

The method ndo_start_xmit() is defined as returning an 'netdev_tx_t', which is a typedef for an enum type, but the implementation in this driver returns an 'int'.

2012-08-13workqueue: use mod_delayed_work() instead of cancel + queueTejun Heo1-3/+2
Convert delayed_work users doing cancel_delayed_work() followed by queue_delayed_work() to mod_delayed_work(). Most conversions are straight-forward. Ones worth mentioning are, * drivers/edac/edac_mc.c: edac_mc_workq_setup() converted to always use mod_delayed_work() and cancel loop in edac_mc_reset_delay_period() is dropped. * drivers/platform/x86/thinkpad_acpi.c: No need to remember whether watchdog is active or not. @fan_watchdog_active and related code dropped. * drivers/power/charger-manager.c: Seemingly a lot of delayed_work_pending() abuse going on here. [delayed_]work_pending() are unsynchronized and racy when used like this. I converted one instance in fullbatt_handler(). Please conver the rest so that it invokes workqueue APIs for the intended target state rather than trying to game work item pending state transitions. e.g. if timer should be modified - call mod_delayed_work(), canceled - call cancel_delayed_work[_sync](). * drivers/thermal/thermal_sys.c: thermal_zone_device_set_polling() simplified. Note that round_jiffies() calls in this function are meaningless. round_jiffies() work on absolute jiffies not delta delay used by delayed_work. v2: Tomi pointed out that __cancel_delayed_work() users can't be safely converted to mod_delayed_work(). They could be calling it from irq context and if that happens while delayed_work_timer_fn() is running, it could deadlock. __cancel_delayed_work() users are dropped.

2011-10-19net: add skb frag size accessorsEric Dumazet1-5/+5
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.

2011-10-10RDMA/nes: Support for Packed And Unaligned fpdusFaisal Latif1-0/+4
Support for Packed and Unaligned (PAU) FPDUs is needed for interoperability between NES and non-NES nodes. When the NES hardware detects a PAU frame, it will pass it to the driver to process the frame. NES driver creates a new frame for each FPDU and forwards it to the hardware to be sent to its associated qp.

2011-04-29ethtool: cosmetic: Use ethtool ethtool_cmd_speed APIDavid Decotigny1-2/+2
This updates the network drivers so that they don't access the ethtool_cmd::speed field directly, but use ethtool_cmd_speed() instead. For most of the drivers, these changes are purely cosmetic and don't fix any problem, such as for those 1GbE/10GbE drivers that indirectly call their own ethtool get_settings()/mii_ethtool_gset(). The changes are meant to enforce code consistency and provide robustness with future larger throughputs, at the expense of a few CPU cycles for each ethtool operation. All drivers compiled with make allyesconfig ion x86_64 have been updated.

2011-01-16RDMA/nes: Fix incorrect SFP+ link status detection on driver initMaciej Sosnowski1-4/+39
During iw_nes initialization the link status for SFP+ PHY is always detected as "up" regardless of real state (cable either connected or disconnected). Add SFP+ PHY specific link status detection to the iw_nes initialization procedure. Use link status recheck for netdev_open to detect delayed state updates.

2011-01-16RDMA/nes: Generate IB_EVENT_PORT_ERR/PORT_ACTIVE eventsMaciej Sosnowski1-8/+27
Depending on link state change, IB_EVENT_PORT_ERR or IB_EVENT_PORT_ACTIVE should be generated when handling MAC interrupts. Plugging in a cable happens to result in series of interrupts changing driver's link state a number of times before finally staying at link up (e.g. link up, link down, link up, link down, ..., link up). To prevent sending series of redundant IB_EVENT_PORT_ACTIVE and IB_EVENT_PORT_ERR events, we use a timer to debounce them in nes_port_ibevent().
