[PATCH OLK-5.10] x86/sgx: Break up long non-preemptible delays in sgx_vepc_release()

From: Jack Wang <jinpu.wang(a)ionos.com> mainline inclusion from mainline-v6.6-rc1 commit 3d7d72a34e05b23e21bafc8bfb861e73c86b31f3 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I9TZZB Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?… -------------------------------- On large enclaves we hit the softlockup warning with following call trace: xa_erase() sgx_vepc_release() __fput() task_work_run() do_exit() The latency issue is similar to the one fixed in: 8795359e35bc ("x86/sgx: Silence softlockup detection when releasing large enclaves") The test system has 64GB of enclave memory, and all is assigned to a single VM. Release of 'vepc' takes a longer time and causes long latencies, which triggers the softlockup warning. Add cond_resched() to give other tasks a chance to run and reduce latencies, which also avoids the softlockup detector.

The driver uses endpoint-sized USB transfer buffers but had no sanity checks on the sizes. This can lead to zero-size-pointer dereferences or overflowed transfer buffers in ni6501_port_command() and ni6501_counter_command() if a (malicious) device has smaller max-packet sizes than expected (or when doing descriptor fuzz testing). Add the missing sanity checks to probe().
