Unexpected behavior vs PS3: sysFsReaddir not breaking loop; cUrl: CELL_ENOTMOUNTED “/dev/urandom”

[rusak47]

Quick summary

I'm testing application that uses google drive api via curl.
In the process of debugging app, i've noticed that some functions doesn't work the same as on real PS3 hardware.

1. the main issue: sysFsReaddir stops on the last available path and doesn't break a loop, while on PS3 it works as expected.
2. for curl there is no entropy source, yet it's not recorded in emulator log:
   • in RPCS3 logs you can find only "SYS: 'sys_fs_open' failed with 0x8001003a : CELL_ENOTMOUNTED, “/dev/urandom” "
   • while in curl logs from app there is: INFO: Failed - PolarSSL: ctr_drbg_init returned (-0x0034) CTR_DRBG - The entropy source failed

Details

1. On real PS3 this code is working as expected without introduced 'previousEntry' check. On RPCS3 'while' keeps looping on the last entry. Based on the result from PS3, i believe that on the next loop after last record read "entry.d_name" should be empty.

        std::string previousEntry = "";
        while (!sysFsReaddir(fd, &entry, &read) && strlen(entry.d_name) > 0)
        {
            debugPrintf("Reading directory (%s)....\n", entry.d_name);
            if(strcmp(previousEntry.c_str(),entry.d_name) == 0){
                debugPrintf("Double reading resource (%s) - breaking loop.\n", entry.d_name);
                break;
            }

            previousEntry = entry.d_name;
            if (strcmp(entry.d_name, ".") == 0 || strcmp(entry.d_name, "..") == 0) {
                continue;
            }
            ....
         }
