2014-06-05IB/core: Fix kobject leak on device register error flowHaggai Eran
The ports kobject isn't being released during error flow in device registration. This patch refactors the ports kobject cleanup into a single function called from both the error flow in device registration and from the unregistration function. A couple of attributes aren't being deleted (iw_stats_group, and ib_class_attributes). While this may be handled implicitly by the destruction of their kobjects, it seems better to handle all the attributes the same way.

2014-06-04IB/core: Fix port kobject deletion during error flowHaggai Eran
When encountering an error during the add_port function, adding a port to sysfs, the port kobject is freed without being deleted from sysfs. Instead of freeing it directly, the patch uses kobject_put to release the kobject and delete it.

2014-06-04IB/core: Remove unneeded kobject_get/put callsHaggai Eran
The ib_core module will call kobject_get on the parent object of each kobject it creates. This is redundant since kobject_add does that anyway. As a side effect, this patch should fix leaking the ports kobject and the device kobject during unregister flow, since the previous code didn't seem to take into account the kobject_get calls on behalf of the child kobjects.

2012-04-02IB/core: Don't return EINVAL from sysfs rate attribute for invalid speedsRoland Dreier
Commit e9319b0cb00d ("IB/core: Fix SDR rates in sysfs") changed our sysfs rate attribute to return EINVAL to userspace if the underlying device driver returns an invalid rate. Apparently some drivers do this when the link is down and some userspace pukes if it gets an error when reading this attribute, so avoid a regression by not return an error to match the old code.

2012-03-05IB: Use central enum for speed instead of hard-coded valuesOr Gerlitz

2010-05-21IB/core: Allow device-specific per-port sysfs filesRalph Campbell
Add a new parameter to ib_register_device() so that low-level device drivers can pass in a pointer to a callback function that will be called for each port that is registered in sysfs. This allows low-level device drivers to create files in /sys/class/infiniband/<hca>/ports/<N>/ without having to poke through the internals of the RDMA sysfs handling.

Constify struct sysfs_ops. This is part of the ops structure constification effort started by Arjan van de Ven et al. Benefits of this constification: * prevents modification of data that is shared (referenced) by many other structure instances at runtime * detects/prevents accidental (but not intentional) modification attempts on archs that enforce read-only kernel data at runtime * potentially better optimized code as the compiler can assume that the const data cannot be changed * the compiler/linker move const data into .rodata and therefore exclude them from false sharing Signed-off-by: Emese Revfy <re.emese@gmail.com> Acked-by: David Teigland <teigland@redhat.com> Acked-by: Matt Domsch <Matt_Domsch@dell.com> Acked-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Acked-by: Hans J.

In the near future, the driver core is going to not allow direct access to the driver_data pointer in struct device. Instead, the functions dev_get_drvdata() and dev_set_drvdata() should be used.

2009-03-04IB: Remove useless ibdev_is_alive() tests from sysfs codeRoland Dreier
Some attribute show functions test ibdev_is_alive() to make sure that it's OK to access device state. However, the sysfs attributes will not be registered until the device is fully initialized, and they'll be unregistered before anything is torn down, so ibdev_is_alive() doesn't do anything useful. Remove it. Signed-off-by: Roland Dreier <rolandd@cisco.com>
2009-02-25IB: Remove sysfs files before unregistering deviceRoland Dreier
Move the ib_device_unregister_sysfs() call from ib_dealloc_device() to ib_unregister_device(). The old code allows device unregister to proceed even if some sysfs files are open, which leaves a window where userspace can open a file before a device is removed but then end up reading the file after the device is removed, which leads to various kernel crashes either because the device data structure is freed or because the low-level driver code is gone after module removal. By not returning from ib_unregister_device() until after all sysfs entries are removed, we make sure that data structures and/or module code is not freed until after all sysfs access is done.

2008-07-14RDMA/core: Add iWARP protocol statistics attributes in sysfsSteve Wise
This patch adds a sysfs attribute group called "proto_stats" under /sys/class/infiniband/$device/ and populates this group with protocol statistics if they exist for a given device. Currently, only iWARP stats are defined, but the code is designed to allow InfiniBand protocol stats if they become available. These stats are per-device and more importantly -not- per port. Details: - Add union rdma_protocol_stats in ib_verbs.h. This union allows defining transport-specific stats. Currently only iwarp stats are defined. - Add struct iw_protocol_stats to define the current set of iwarp protocol stats. - Add new ib_device method called get_proto_stats() to return protocol statistics. - Add logic in core/sysfs.c to create iwarp protocol stats attributes if the device is an RNIC and has a get_proto_stats() method.

2007-07-11sysfs: kill unnecessary attribute->ownerTejun Heo
sysfs is now completely out of driver/module lifetime game. After deletion, a sysfs node doesn't access anything outside sysfs proper, so there's no reason to hold onto the attribute owners. Note that often the wrong modules were accounted for as owners leading to accessing removed modules. This patch kills now unnecessary attribute->owner. Note that with this change, userland holding a sysfs node does not prevent the backing module from being unloaded.
