nes_reg_phys_mr() returns ERR_PTRs on error. It doesn't return NULL. This bug has been there for a while, but we recently changed from calling a function pointer to calling nes_reg_phys_mr() directly so now Smatch is able to detect the bug.

This patch split up struct ib_send_wr so that all non-trivial verbs use their own structure which embedds struct ib_send_wr. This dramaticly shrinks the size of a WR for most common operations: sizeof(struct ib_send_wr) (old): 96 sizeof(struct ib_send_wr): 48 sizeof(struct ib_rdma_wr): 64 sizeof(struct ib_atomic_wr): 96 sizeof(struct ib_ud_wr): 88 sizeof(struct ib_fast_reg_wr): 88 sizeof(struct ib_bind_mw_wr): 96 sizeof(struct ib_sig_handover_wr): 80 And with Sagi's pending MR rework the fast registration WR will also be down to a reasonable size: sizeof(struct ib_fastreg_wr): 64 Signed-off-by: NChristoph Hellwig <hch@lst.de> Reviewed-by: Bart Van Assche <bart.vanassche@sandisk.com> [srp, srpt] Reviewed-by: Chuck Lever <chuck.lever@oracle.com> [sunrpc] Tested-by: NHaggai Eran <haggaie@mellanox.com> Tested-by: NSagi Grimberg <sagig@mellanox.com> Tested-by: NSteve Wise <swise@opengridcomputing.com>

In order to support alternate sized MADs (and variable sized MADs on OPA devices) add in/out MAD size parameters to the process_mad core call. 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.

As of commit 5eb620c8 "IB/core: Add helpers for uncached GID and P_Key searches"; pkey_tbl_len and gid_tbl_len are immutable data which are stored in the ib_device. The per port core capability flags to be added later are also immutable data to be stored in the ib_device object. In preparation for this create a structure for per port immutable data and place the pkey and gid table lengths within this structure. "get_port_immutable" is added as a mandatory device function to allow the drivers to fill in this data.

由 Yann Droneaud 提交于
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().
