2016-05-13RDMA/nes: replace custom print_hex_dump()Andy Shevchenko1-57/+3
There is no need to duplicate a lot of code that is in the kernel library for ages. Replace duplicating code by calling to print_hex_dump() directly. Note that output is slightly changed: - hex and ascii parts have just two spaces delimeter - there is no delimeter for ascii portions - file and line removed from prefix (they were redundant anyway since previous output shows same closer enough) Signed-off-by: Andy Shevchenko <[email protected]> Reviewed-by: Tatyana Nikolova <[email protected]> Signed-off-by: Doug Ledford <[email protected]>

The SRP initiator allows to set max_sectors to a value that exceeds the largest amount of data that can be mapped at once with an mlx4 HCA using fast registration and a page size of 4 KB. Hence modify ib_map_mr_sg() such that it can map partial sg-elements. If an sg-element has been mapped partially, let the caller know which fraction has been mapped by adjusting *sg_offset.

In addition, add an out_mad_pkey_index to communicate the pkey index the driver wishes the MAD stack to use when sending OPA MAD responses. The out MAD size and the out MAD PKey index are required by the MAD stack to generate responses on OPA devices. Furthermore, the in and out MAD parameters are made generic by specifying them as ib_mad_hdr rather than ib_mad. Drivers are modified as needed and are protected by BUG_ON flags if the MAD sizes passed to them is incorrect.

2014-03-17IB/nes: Return an error on ib_copy_from_udata() failure instead of NULLYann Droneaud1-1/+1
In case of error while accessing to userspace memory, function nes_create_qp() returns NULL instead of an error code wrapped through ERR_PTR(). But NULL is not expected by ib_uverbs_create_qp(), as it check for error with IS_ERR(). As page 0 is likely not mapped, it is going to trigger an Oops when the kernel will try to dereference NULL pointer to access to struct ib_qp's fields. In some rare cases, page 0 could be mapped by userspace, which could turn this bug to a vulnerability that could be exploited: the function pointers in struct ib_device will be under userspace total control. This was caught when using spatch (aka. coccinelle) to rewrite calls to ib_copy_{from,to}_udata().
