The conversion from offsetof() calculations to sizeof()
wrongly behaved for missed exact size and in scenario with
more than one flow.
In such scenario we got "create flow failed, flow 10: 8 bytes
left from uverb cmd" error, which is wrong because the size of
kern_spec is exactly 8 bytes, and we were not supposed to fail.

In smartnic env, the host (PF) driver might not be an e-switch

The __get_txreq() function can return a pointer, ERR_PTR(-EBUSY), or NULL.
All of the relevant call sites look for IS_ERR, so the NULL return would
lead to a NULL pointer exception.
Do not use the ERR_PTR mechanism for this function.
Update all call sites to handle the return value correctly.

Flows can be created on UD and RAW_PACKET QP types. Attempts to provide
other QP types as an input causes to various unpredictable failures.
The reason is that in order to support all various types (e.g. XRC), we
are supposed to use real_qp handle and not qp handle and expect to
driver/FW to fail such (XRC) flows. The simpler and safer variant is to
ban all QP types except UD and RAW_PACKET, instead of relying on
driver/FW.

- More work cleaning up the RDMA CM code
- Usual driver bug fixes and cleanups for qedr, qib, hfi1, hns, i40iw, iw_cxgb4, mlx5, rxe
- Driver specific resource tracking and reporting via netlink
- Continued work for name space support from Parav
- MPLS support for the verbs flow steering uAPI
- A few tricky IPoIB fixes improving robustness
- HFI1 driver support for the '16B' management packet format
- Some auditing to not print kernel pointers via %llx or similar
- Mark the entire 'UCM' user-space interface as BROKEN with the intent to remove it
entirely. The user space side of this was long ago replaced with RDMA-CM and
syzkaller is finding bugs in the residual UCM interface nobody wishes to fix because
nobody uses it.

Pull rdma updates from Jason Gunthorpe:
"This has been a quiet cycle for RDMA, the big bulk is the usual
smallish driver updates and bug fixes. About four new uAPI related
things. Not as much Szykaller patches this time, the bugs it finds are
getting harder to fix.
Summary:
- More work cleaning up the RDMA CM code
- Usual driver bug fixes and cleanups for qedr, qib, hfi1, hns,
i40iw, iw_cxgb4, mlx5, rxe
- Driver specific resource tracking and reporting via netlink
- Continued work for name space support from Parav
- MPLS support for the verbs flow steering uAPI
- A few tricky IPoIB fixes improving robustness
- HFI1 driver support for the '16B' management packet format
- Some auditing to not print kernel pointers via %llx or similar
- Mark the entire 'UCM' user-space interface as BROKEN with the
intent to remove it entirely. The user space side of this was long
ago replaced with RDMA-CM and syzkaller is finding bugs in the
residual UCM interface nobody wishes to fix because nobody uses it.
- Purge more bogus BUG_ON's from Leon
- 'flow counters' verbs uAPI
- T10 fixups for iser/isert, these are Acked by Martin but going
through the RDMA tree due to dependencies"

Merge tag 'overflow-v4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull overflow updates from Kees Cook:
"This adds the new overflow checking helpers and adds them to the
2-factor argument allocators. And this adds the saturating size
helpers and does a treewide replacement for the struct_size() usage.
Additionally this adds the overflow testing modules to make sure
everything works.
I'm still working on the treewide replacements for allocators with
"simple" multiplied arguments:
*alloc(a * b, ...) -> *alloc_array(a, b, ...)
and
*zalloc(a * b, ...) -> *calloc(a, b, ...)
as well as the more complex cases, but that's separable from this
portion of the series. I expect to have the rest sent before -rc1
closes; there are a lot of messy cases to clean up.
Summary:
- Introduce arithmetic overflow test helper functions (Rasmus)
- Use overflow helpers in 2-factor allocators (Kees, Rasmus)
- Introduce overflow test module (Rasmus, Kees)
- Introduce saturating size helper functions (Matthew, Kees)
- Treewide use of struct_size() for allocators (Kees)"

overflow.h: Add allocation size calculation helpers
test_overflow: Report test failures
test_overflow: macrofy some more, do more tests for free
lib: add runtime test of check_*_overflow functions
compiler.h: enable builtin overflow checkers and add fallback code
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
void *entry[];
};
instance = kmalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kmalloc(struct_size(instance, entry, count), GFP_KERNEL);
This patch makes the changes for kmalloc()-family (and kvmalloc()-family)
uses. It was done via automatic conversion with manual review for the
"CHECKME" non-standard cases noted below, using the following Coccinelle
script:
// pkey_cache = kmalloc(sizeof *pkey_cache + tprops->pkey_tbl_len *
// sizeof *pkey_cache->table, GFP_KERNEL);

The following code fails to allocate a buffer for the
tail address that the hardware DMAs into when the user
context DMA_RTAIL is set.
if (HFI1_CAP_KGET_MASK(rcd->flags, DMA_RTAIL)) {
rcd->rcvhdrtail_kvaddr = dma_zalloc_coherent(
&dd->pcidev->dev, PAGE_SIZE, &dma_hdrqtail,
gfp_flags);
if (!rcd->rcvhdrtail_kvaddr)
goto bail_free;
rcd->rcvhdrqtailaddr_dma = dma_hdrqtail;
}
So the rcvhdrtail_kvaddr would then be NULL.
The mmap logic fails to check for a NULL rcvhdrtail_kvaddr.
The fix is to test for both user and kernel DMA_TAIL options
during the allocation as well as testing for a NULL
rcvhdrtail_kvaddr during the mmap processing.
Additionally, all downstream testing of the capmask for DMA_RTAIL
have been eliminated in favor of testing rcvhdrtail_kvaddr.

if there is any error after that, especially the copy_to_user().
But in parallel, ucma_leave_multicast() could find this "mc"
through idr_find() before ucma_process_join() frees it, since it
is already published.
So "mc" could be used in ucma_leave_multicast() after it is been
allocated and freed in ucma_process_join(), since we don't refcnt
it.
Fix this by separating "publish" from ID allocation, so that we
can get an ID first and publish it later after copy_to_user().

The newly added fill_res_ep_entry function fails to link if
CONFIG_INFINIBAND_ADDR_TRANS is not set:
drivers/infiniband/hw/cxgb4/restrack.o: In function `fill_res_ep_entry':
restrack.c:(.text+0x3cc): undefined reference to `rdma_res_to_id'

This adds a Kconfig dependency for the driver.

No reason to use hard-coded protection information checks in ib_isert
driver. Use check masks from RDMA core driver.
Also, while we here, reduce the number of instructions made for setting
the check mask (no need to do bitwise or with 0 since we zero the mask
in the beginning of the function).

This series comes to allow user space applications to monitor real time
traffic activity and events of the verbs objects it manages, e.g.:
ibv_qp, ibv_wq, ibv_flow.
This API enables generic counters creation and define mapping
to association with a verbs object, current mlx5 driver using
this API for flow counters.
With this API, an application can monitor the entire life cycle of
object activity, defined here as a static counters attachment.
This API also allows dynamic counters monitoring of measurement points
for a partial period in the verbs object life cycle.
In addition it presents the implementation of the generic counters interface.
This will be achieved by extending flow creation by adding a new flow count
specification type which allows the user to associate a previously created
flow counters using the generic verbs counters interface to the created flow,
once associated the user could read statistics by using the read function of
the generic counters interface.
The API includes:
1. create and destroyed API of a new counters objects
2. read the counters values from HW
Note:
Attaching API to allow application to define the measurement points per objects
is a user space only API and this data is passed to kernel when the counted
object (e.g. flow) is created with the counters object.
