- Added UID member to nvsciipc_config_entry data structure. this is needed for implementing test_nvsciipc_cfgblob in linux. - removed static from ioctl function to attach eBPF program - add error-injection.h and ALLOW_ERROR_INJECTION macro to ioctl to use bpf_override_return() JIRA NVIPC-2817 Change-Id: Ic27156e321368041f41fbabff9e6375140fe1d0e Signed-off-by: Suneel Kumar Pemmineti <spemmineti@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/c/linux-nv-oot/+/3301786 Tested-by: Joshua Cha <joshuac@nvidia.com> GVS: buildbot_gerritrpt <buildbot_gerritrpt@nvidia.com> Reviewed-by: Simon Je <sje@nvidia.com>
