| H A D | kern_environment.c | diff 148585 Sun Jul 31 08:28:35 MDT 2005 netchild Add bounds checking to the setenv part of the kernel environment. This has no security implications since only root is allowed to use kenv(1) (and corrupt the kernel memory after adding too much variables previous to this commit). This is based upon the PR [1] mentioned below, but extended to check both bounds (in case of an overflow of the counting variable) and to comply to the style of the function. An overflow of the counting variable shouldn't happen after adding the check for the upper bound, but better safe than sorry (in case some other function in the kernel overwrites random memory). An interested soul may want to add a printf to notify root in case the bounds are hit. Also allocate KENV_SIZE+1 entries (the array is NULL-terminated), since the comment for KENV_SIZE says it's the maximum number of environment strings.
