2020-06-23RDMA: Add dedicated CM_ID resource tracker functionMaor Gottlieb1-7/+2
In order to avoid double multiplexing of the resource when it is a cm id, add a dedicated callback function. In addition remove fill_res_entry which is not used anymore.

2019-04-27netlink: make nla_nest_start() add NLA_F_NESTED flagMichal Kubecek1-4/+4
Even if the NLA_F_NESTED flag was introduced more than 11 years ago, most netlink based interfaces (including recently added ones) are still not setting it in kernel generated messages. Without the flag, message parsers not aware of attribute semantics (e.g. wireshark dissector or libmnl's mnl_nlmsg_fprintf()) cannot recognize nested attributes and won't display the structure of their contents. Unfortunately we cannot just add the flag everywhere as there may be userspace applications which check nlattr::nla_type directly rather than through a helper masking out the flags. Therefore the patch renames nla_nest_start() to nla_nest_start_noflag() and introduces nla_nest_start() as a wrapper adding NLA_F_NESTED. The calls which add NLA_F_NESTED manually are rewritten to use nla_nest_start(). Except for changes in include/net/netlink.h, the patch was generated using this semantic patch: @@ expression E1, E2; @@ -nla_nest_start(E1, E2) +nla_nest_start_noflag(E1, E2) @@ expression E1, E2; @@ -nla_nest_start_noflag(E1, E2 | NLA_F_NESTED) +nla_nest_start(E1, E2) Signed-off-by: Michal Kubecek <mkubecek@suse.cz> Acked-by: Jiri Pirko <jiri@mellanox.com> Acked-by: David Ahern <dsahern@gmail.com> Signed-off-by: David S.

2018-05-15iw_cxgb4: remove wr_id attributesSteve Wise1-55/+0
Remove sq/rq wr_id attributes because typically they are pointers and we don't want to pass up kernel pointers. Fixes: 056f9c7f39bf ("iw_cxgb4: dump detailed driver-specific QP information") Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>

2018-05-03iw_cxgb4: dump detailed driver-specific QP informationSteve Wise1-0/+248
Provide a cxgb4-specific function to fill in qp state details. This allows dumping important c4iw_qp state useful for debugging. Included in the dump are the t4_sq, t4_rq structs, plus a dump of the t4_swsqe and t4swrqe descriptors for the first and last pending entries.
