Hello Bjorn Andersson,
The patch 7f0dd07a9b29: "remoteproc: qcom: mdt_loader: Refactor MDT
loader" from Jan 27, 2017, leads to the following static checker
warning:
drivers/soc/qcom/mdt_loader.c:171 qcom_mdt_load()
warn: unsigned 'offset' is never less than zero.
drivers/soc/qcom/mdt_loader.c
164 for (i = 0; i < ehdr->e_phnum; i++) {
165 phdr = &phdrs[i];
166
167 if (!mdt_phdr_valid(phdr))
168 continue;
169
170 offset = phdr->p_paddr - mem_reloc;
171 if (offset < 0 || offset + phdr->p_memsz > mem_size) {
^^^^^^^^^^
offset is size_t.
172 dev_err(dev, "segment outside memory range\n");
173 ret = -EINVAL;
174 break;
175 }
176
regards,
dan carpenter
