# http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=518559
#
# Doesn't work with a non-iterable nsswitch source
#
# Currently, "finger tabbott" works by iterating through the list of users
# on the system using getpwent and checking if any of them match
# "tabbott".
#
# Some nsswitch backends (including Hesiod and LDAP[1]) do not support
# iterating through the complete list of users. These nsswitch backends
# instead only fully support looking up a user's information by username
# or uid.
#
# So, if tabbott is a user whose nsswitch information comes from LDAP,
# then "finger tabbott" will incorrectly report "finger: tabbott: no such
# user." "finger -m tabbott" does work correctly, however, because it
# looks up the matching username using getpwnam.
#
# A fix for this is to always look up an argument to finger for a username
# match, and having -m only control whether finger searches the entire
# user database for real name matches. Patch attached.
#
# This patch has the advantageous side effect that if there are some real
# name matches and a username match, finger will always display the
# username match first (rather than in some random place in the list).
#
# -Tim Abbott
#
# [1] with LDAP, it is typically the case that one can iterate through
# only the first 100 results from a query.

#
# finger segfaults when it comes across a netgroup entry in /etc/passwd.
# A netgroup entry doesn't include many of the fields in a normal passwd
# entry, so pw->pw_gecos is set to NULL, which causes finger to core dump.
#
# Here is part of a /etc/passwd file with a netgroup entry:
#
# nobody:x:65534:65534:nobody:/nonexistent:/bin/sh +@operator
#
# This patch sidesteps what finger considers a malformed passwd entry:

# Decrease timeout length during connect().
# In cases where a name server is answering with A as well as AAAA
# records, but the system to be queried has lost a corresponding address,
# the TCP handshake timeout will cause a long delay before allowing the
# query of the next address family, or the next address in general.
# .
# The use of a trivial signal handler for SIGALRM allows the reduction of
# this timeout, thus producing better responsiveness for the interactive
# user of the Finger service.
