Package: wmifs Version: 1.8-1 I noticed that wmifs was randomly crashing on my laptop. I have no idea how to reproduce it besides letting it run for a long time, it didn't seem to be associated with hibernation or anything else obvious. If I have multiple instances running, usually only one will crash while the others continue without issue.
Running it under gdb with wmifs-dbgsym installed produced this trace: Program received signal SIGSEGV, Segmentation fault. _IO_fgets (buf=0x7fffffffd9d0 "\001", n=512, fp=0x0) at iofgets.c:47 47 iofgets.c: No such file or directory. (gdb) bt #0 _IO_fgets (buf=0x7fffffffd9d0 "\001", n=512, fp=0x0) at iofgets.c:47 #1 0x0000555555556d1f in fgets (__stream=0x0, __n=512, __s=0x7fffffffd9d0 "\001") at /usr/include/x86_64-linux-gnu/bits/stdio2.h:263 #2 get_statistics (devname=<optimized out>, ip=0x7fffffffdc70, op=0x7fffffffdc78, is=0x7fffffffdc80, os=0x7fffffffdc88) at wmifs.c:767 #3 0x00005555555573b9 in wmifs_routine (argc=<optimized out>, argv=<optimized out>) at wmifs.c:555 #4 0x0000555555555dbe in main (argc=5, argv=0x7fffffffe198) at wmifs.c:367 Apparently the fopen() on wmifs.c line 766 can fail in some cases, and that needs to be checked for to avoid passing a NULL file pointer to fgets(). It could be as simple as inserting if (!fp) { return -1; } to match the minimal error handling on subsequent lines when an fgets() fails.
