package/linux-pam: bump version to 1.2.1

Browse Source 
Move to the latest release of linux-pam. This allows us to remove
a number of patches and consolidate the existing ones :

- 0001-configure.patch
- 0007-rhosts.patch

these two patches deal with the ruserok function, which is not
usable with uclibc. Consolidated into
0002-Conditionally-compile-per-ruserok-availability.patch.

- 0003-group.patch
- 0005-succeed.patch
- 0006-time.patch

these three patches deal with the innetgr function, which is not
usable with uclibc. Consolidated into
0003-Conditionally-compile-per-innetgr-availability.patch.

- 0004-mkdir.patch

Fixed in upstream, no longer required.

- 0002-doc-makefile-am.patch

renamed to 0001-doc-makefile-am.patch.

- 0008-fix-CVE-2014-2583.patch
- 0009-fix-CVE-2013-7041.patch

These patches are already included in the new release and so
can be safely deleted.

Subject: pam_timestamp: fix potential directory traversal issue (ticket #27)
pam_timestamp uses values of PAM_RUSER and PAM_TTY as components of
the timestamp pathname it creates, so extra care should be taken to
avoid potential directory traversal issues.
* modules/pam_timestamp/pam_timestamp.c (check_tty): Treat
"." and ".." tty values as invalid.
(get_ruser): Treat "." and ".." ruser values, as well as any ruser
value containing '/', as invalid.

From: "Dmitry V. Levin" <ldv@altlinux.org>

Subject: pam_userdb: fix password hash comparison
Starting with commit Linux-PAM-0-77-28-g0b3e583 that introduced hashed
passwords support in pam_userdb, hashes are compared case-insensitively.
This bug leads to accepting hashes for completely different passwords in
addition to those that should be accepted.
Additionally, commit Linux-PAM-1_1_6-13-ge2a8187 that added support for
modern password hashes with different lengths and settings, did not
update the hash comparison accordingly, which leads to accepting
computed hashes longer than stored hashes when the latter is a prefix
of the former.
* modules/pam_userdb/pam_userdb.c (user_lookup): Reject the computed
hash whose length differs from the stored hash length.
Compare computed and stored hashes case-sensitively.
Fixes CVE-2013-7041.
