commit f2625f7db4dd0bbd16a9c7d2950e7621f9aa57ad upstream.
cma_accept_iw() needs to return an error if conn_params is NULL.
Since this is coming from user space, we can crash.

commit 2fe2f378dd45847d2643638c07a7658822087836 upstream.
The array ib_mad_mgmt_class_table.method_table has MAX_MGMT_CLASS
(80) elements. Hence compare the array index with that value instead
of with IB_MGMT_MAX_METHODS (128). This patch avoids that Coverity
reports the following:
Overrunning array class->method_table of 80 8-byte elements at element index 127 (byte offset 1016) using index convert_mgmt_class(mad_hdr->mgmt_class) (which evaluates to 127).
Fixes: commit b7ab0b19a85f ("IB/mad: Verify mgmt class in received MADs")

commit 9db0ff53cb9b43ed75bacd42a89c1a0ab048b2b0 upstream.
When there is a CM id object that has port assigned to it, it means that
the cm-id asked for the specific port that it should go by it, but if
that port was removed (hot-unplug event) the cm-id was not updated.
In order to fix that the port keeps a list of all the cm-id's that are
planning to go by it, whenever the port is removed it marks all of them
as invalid.
This commit fixes a kernel panic which happens when running traffic between
guests and we force reboot a guest mid traffic, it triggers a kernel panic:

commit 5b810a242c28e1d8d64d718cebe75b79d86a0b2d upstream.
The real QP is destroyed in case of the ref count reaches zero, but
for XRC target QPs this call was missed and caused to QP leaks.
Let's call to destroy for all flows.

commit 68c6bcdd8bd00394c234b915ab9b97c74104130c upstream.
The function send_leave sets the member: group->query_id
(group->query_id = ret) after calling the sa_query, but leave_handler
can be executed before the setting and it might delete the group object,
and will get a memory corruption.
Additionally, this patch gets rid of group->query_id variable which is
not used.

commit 0ca81a2840f77855bbad1b9f172c545c4dc9e6a4 upstream.
ib_send_cm_sidr_rep could sometimes erase the node from the sidr
(depending on errors in the process). Since ib_send_cm_sidr_rep is
called both from cm_sidr_req_handler and cm_destroy_id, cm_id_priv
could be either erased from the rb_tree twice or not erased at all.
Fixing that by making sure it's erased only once before freeing
cm_id_priv.

commit 35d4a0b63dc0c6d1177d4f532a9deae958f0662c upstream.
Fixes: 2a72f212263701b927559f6850446421d5906c41 ("IB/uverbs: Remove dev_table")
Before this commit there was a device look-up table that was protected
by a spin_lock used by ib_uverbs_open and by ib_uverbs_remove_one. When
it was dropped and container_of was used instead, it enabled the race
with remove_one as dev might be freed just after:
dev = container_of(inode->i_cdev, struct ib_uverbs_device, cdev) but
before the kref_get.
In addition, this buggy patch added some dead code as
container_of(x,y,z) can never be NULL and so dev can never be NULL.
As a result the comment above ib_uverbs_open saying "the open method
will either immediately run -ENXIO" is wrong as it can never happen.
The solution follows Jason Gunthorpe suggestion from below URL:
https://www.mail-archive.com/linux-rdma@vger.kernel.org/msg25692.html
cdev will hold a kref on the parent (the containing structure,
ib_uverbs_device) and only when that kref is released it is
guaranteed that open will never be called again.
In addition, fixes the active count scheme to use an atomic
not a kref to prevent WARN_ON as pointed by above comment
from Jason.

commit b632ffa7cee439ba5dce3b3bc4a5cbe2b3e20133 upstream.
We have many WR opcodes that are only supported in kernel space
and/or require optional information to be copied into the WR
structure. Reject all those not explicitly handled so that we
can't pass invalid information to drivers.
