Since we need to make sure external contributors code actually compiles prior to merging. To get access to the forked repos merge request we need to switch over our push to pull_request. In addition we're fixing up some Naming Conventions, adding aarch64 to this branch and fixing the naming so that we can quickly identify if the CI is for x86_64.

Also disable the process-pull-request until the utf-8 situation is resolved.

selftests/bpf: Extend crypto_sanity selftest with invalid dst buffer
3aa9b9a
Small cleanup and test extension to probe the bpf_crypto_{encrypt,decrypt}()
kfunc when a bad dst buffer is passed in to assert that an error is returned.
Also, encrypt_sanity() and skb_crypto_setup() were explicit to set the global
status variable to zero before any test, so do the same for decrypt_sanity().
Do not explicitly zero the on-stack err before bpf_crypto_ctx_create() given
the kfunc is expected to do it internally for the success case.

smb: smbdirect: destroy QP before mem pools on accept failure
383a948
On the rdma_accept_failed error path of
smbdirect_accept_connect_request(), the receive io posted just above is
owned by the QP (recv_io is set to NULL after a successful post). The
error path fell through to smbdirect_connection_destroy_mem_pools()
before smbdirect_connection_destroy_qp(), so the mem pools and the
recv_io slab cache were destroyed while that recv_io was still
outstanding on the QP.
The drain in smbdirect_connection_destroy_qp() (ib_drain_qp()) is what
runs the recv completion that returns the recv_io to the free list, so
destroying the pools first leaves the object outstanding at
kmem_cache_destroy() time ("Slab cache still has objects") and later
frees it into an already-destroyed mempool (mempool_free_bulk
NULL-pointer dereference).
Give rdma_accept_failed its own teardown that drains the QP first, then
destroys the mem pools, and returns. The remaining labels
(post_recv_io_failed onward) run before the recv_io was ever posted, so
they keep the mem-pools-then-qp order.
The outstanding recv_io at kmem_cache_destroy() time:

Found with ksmbdzzer [2], a KSMBD fuzzer that drives libFuzzer with a
kcov-dataflow [1] coverage vector: it folds each instrumented
comparison/argument's runtime operand value together with its PC (the
default arm mixes them as pc⊕val) so that a new operand value at a known
site counts as new coverage.
