* Fixed a rather serious bug that presents itself when FreeBSD is configuredBill Paul1995-02-031-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | as an NIS client. The pw_breakout_yp routines that are used to populate the _pw_passwd structire only do anything if the bits in the pw_fields member _pw_passwd are cleared. Unfortunately, we can get into a state where pw_fields has garbage in it right before the YP lookup functions are called, which causes the breakout functions to screw up in a big way. Here's how to duplicate the problem: - Configure FreeBSD as an NIS client - Log in as a user who's password database records reside only in the NIS passwd maps. - Type ps -aux Result: your processes appear to be owned by 'root' or 'deamon.' /bin/ls can exhibit the same problem. The reason this happens: - When ps(1) needs to match a username to a UID, it calls getpwuid(). - root is in the local password file, so getpwuid() calls __hashpw() and __hashpw() populates the _pw_passwd struct, including the pw_fields member. This happens before NIS lookups take place because, by coincidence, ps(1) tends to display processes owned by root before it happens upon a proccess owned by you. - When your UID comes up, __hashpw() fails to find your entry in the local password database, so it bails out, BUT THE BITS IN THE pw_fields STRUCTURE OF _pw_passwd ARE NEVER CLEARED AND STILL CONTAIN INFORMATION FROM THE PREVIOUS CALL TO __hash_pw()!! - If we have NIS enabled, the NIS lookup functions are called. - The pw_breakout_yp routines see that the pw_fields bits are set and decline to place the data retrieved from the NIS passwd maps into the _pw_passwd structure. - getpwuid() returns the results of the last __hashpw() lookup instead of the valid NIS data. - Hijinxs ensue when user_from_uid() caches this bogus information and starts handing out the wrong usernames. AAAARRRRRRRRRGGGGGGHHHHHHHHHH!!! *Please* don't tell me I'm the only person to have noticed this. Fixed by having __hashpw() check the state of pw_fields just before bailing out on a failed lookup and clearing away any leftover garbage. What a fun way to spend an afternoon.

* Small fix to _getyppass(): sometimes we can construct the wrong mapnameBill Paul1995-02-011-1/+2
| | | | | | | when looking for master.passwd.whatever. Notes: svn path=/head/; revision=6095
* Some changes for YP password map handling:Bill Paul1995-01-311-6/+114
| | | | | | | | | | | | | | | | | | | | | | | | - FreeBSD's NIS server can supply a master.passwd map, which has more fields in it than a standard passwd map, so we need a _master_pw_breakout() fuction. - When doing passwd map lookups, look for master.passwd.* by attempting a _yp_first() on master.passwd.byname. If it exists, we're being served by a FreeBSD NIS server and we should use this map. - If we aren't the superuser, retrieve only the standard passwd maps. If we're being served by a FreeBSD system, then the passwd map has no passwords in it, and it won't serve us the master.passwd map unless we're superuser anyway. There's a small speed hit for the superuser inherent in the check for the master.passwd map, but this lets us dynamically decide what to do rather than rely on a non-standard config file somewhere. Since all of this is bypassed for normal users, they shouldn't notice the difference. Notes: svn path=/head/; revision=6076

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | getcwd() has two off-by-one bugs in FreeBSD-2.0: 1. getcwd(buf, size) fails when the size is just large enough. 2. getcwd(buf + 1, 1) incorrectly succeeds when the current directory is "/". buf[0] and buf[2] are clobbered. (I modified Bruce's original patch to return the proper error code [ERANGE] in the case of #2, but otherwise... -DG) This program demonstrates the bug: --- #include <stdlib.h> #include <string.h> #include <stdio.h> #include <unistd.h> int main(void) { char buf[5]; int errors; errors = 0; if (chdir("/tmp") != 0) { perror("chdir"); abort(); } if (getcwd(buf, 5) == NULL) { perror("oops, getcwd failed for buffer size = size required"); ++errors; } if (chdir("/") != 0) { perror("chdir"); abort(); } buf[0] = 0; buf[2] = 1; if (getcwd(buf + 1, 1) != NULL) { fprintf(stderr, "oops, getcwd succeeded for buffer size = one too small\n"); ++errors; } if (buf[0] != 0) { fprintf(stderr, "oops, getcwd scribbled on memory before start of buffer\n"); ++errors; } if (buf[2] != 1) { fprintf(stderr, "oops, getcwd scribbled on memory after end of buffer\n"); ++errors; } exit(errors == 0 ? 0 : 1); } Notes: svn path=/head/; revision=5072
