/proc/*/exe symlinks with trailing garbage
Last modified: 2008-02-07 23:29:22 EST
Description of problem:
I keep finding /proc/*/exe symlinks with trailing garbage on my box:
ultra:[~]$ cat readlink.c
int main(int argc, char *argv)
int i, j, n;
for (i = 1; i < argc; i++)
n = readlink(argv[i], buf, BUFSIZ);
for (j = 0; j < n; j++)
char c = buf[j];
if (c == '\\')
else if (c > 32 && c < 127)
ultra:[~]$ gcc readlink.c -o readlink
ultra:[~]$ ./readlink /proc/30781/exe
Version-Release number of selected component (if applicable):
It seems fairly random which processes will get garbled links, but once a
process has one it keeps it until it's killed as far as I can tell.
Steps to Reproduce:
1. Run the above program on /proc/*/exe
2. Look for junk
