| * | RDMA/siw: Fix user page pinning accountingBernard Metzler2023-02-061-11/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To avoid racing with other user memory reservations, immediately account full amount of pages to be pinned.

| * | RDMA/cxgb4: add null-ptr-check after ip_dev_find()Nikita Zhandarovich2023-02-021-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ip_dev_find() may return NULL and assign it to pdev which is dereferenced later. Fix this by checking the return value of ip_dev_find() for NULL similar to the way it is done with other instances of said function. Found by Linux Verification Center (linuxtesting.org) with SVACE.

| * | RDMA/mlx5: Add work to remove temporary entries from the cacheMichael Guralnik2023-01-273-23/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The non-cache mkeys are stored in the cache only to shorten restarting application time. Don't store them longer than needed. Configure cache entries that store non-cache MRs as temporary entries. If 30 seconds have passed and no user reclaimed the temporarily cached mkeys, an asynchronous work will destroy the mkeys entries.

| * | RDMA/mlx5: Cache all user cacheable mkeys on dereg MR flowMichael Guralnik2023-01-272-13/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, when dereging an MR, if the mkey doesn't belong to a cache entry, it will be destroyed. As a result, the restart of applications with many non-cached mkeys is not efficient since all the mkeys are destroyed and then recreated. This process takes a long time (for 100,000 MRs, it is ~20 seconds for dereg and ~28 seconds for re-reg). To shorten the restart runtime, insert all cacheable mkeys to the cache. If there is no fitting entry to the mkey properties, create a temporary entry that fits it. After a predetermined timeout, the cache entries will shrink to the initial high limit. The mkeys will still be in the cache when consuming them again after an application restart. Therefore, the registration will be much faster (for 100,000 MRs, it is ~4 seconds for dereg and ~5 seconds for re-reg). The temporary cache entries created to store the non-cache mkeys are not exposed through sysfs like the default cache entries.

| * | RDMA/mlx5: Change the cache structure to an RB-treeMichael Guralnik2023-01-273-47/+132
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the cache structure is a static linear array. Therefore, his size is limited to the number of entries in it and is not expandable. The entries are dedicated to mkeys of size 2^x and no access_flags. Mkeys with different properties are not cacheable. In this patch, we change the cache structure to an RB-tree. This will allow to extend the cache to support more entries with different mkey properties.

| * | RDMA/rxe: Replace rxe_map and rxe_phys_buf by xarrayBob Pearson2023-01-273-302/+254
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace struct rxe-phys_buf and struct rxe_map by struct xarray in rxe_verbs.h. This allows using rcu locking on reads for the memory maps stored in each mr. This is based off of a sketch of a patch from Jason Gunthorpe in the link below. Some changes were needed to make this work. It applies cleanly to the current for-next and passes the pyverbs, perftest and the same blktests test cases which run today.

Normal usage in the kernel has page_mask masking out offset in page rather than masking out the page number. The rxe driver had reversed that which was confusing. Implicitly there can be a per mr page_size which was not uniformly supported.

So now it will update the destination address internally only when it is really needed and after passing all the required checks. Which in turn results in a cleaner and more sensible call and error handling flows for the functions that call it directly or indirectly.
