Applications should be opening this\nfile as O_RDONLY. The BPF dmabuf_iter selftest already does this. [1]\n\nUsers are pointing to these selftests as examples of how use udmabuf,\nand encountering permission errors on systems where write permissions\nare not available on /dev/udmabuf. Apply the principle of least\nprivilege to selftests which use udmabuf by removing the write access\nmode from drivers/net/hw/ncdevmem.c.\n\n[1] https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/testing/selftests/bpf/prog_tests/dmabuf_iter.c?h\u003dv7.1#n49\n\nSigned-off-by: T.J.
