Help with linprocfs small patch

[fernape]

Hi,

Could anyone help me with this small patch? I don't know why it doesn't show the proper environment for the process. It seems to show the current process' environment.


/*
* Filler function for proc/pid/environ
*/
static int
linprocfs_doprocenviron(PFS_FILL_ARGS)
{
int i, error;
struct ps_strings pss;
char **ps_envstr;

if (p_cansee(td, p) != 0)
return (0);

error = copyin((void *)p->p_sysent->sv_psstrings, &pss,
sizeof(pss));
if (error)
return (error);

ps_envstr = malloc(pss.ps_nenvstr * sizeof(char *),
M_TEMP, M_WAITOK);

error = copyin((void *)pss.ps_envstr, ps_envstr,
pss.ps_nenvstr * sizeof(char *));

if (error) {
free(ps_envstr, M_TEMP);
return (error);
}

/* NULL separated list of variable=value pais */

for (i = 0; i < pss.ps_nenvstr; i++) {
sbuf_copyin(sb, ps_envstr[i], 0);
}

free(ps_envstr, M_TEMP);
return (0);
}


I'm running this on FreeBSD 8.0-RELEASE-p2.

Thanks in advance
