[Impact]
The nss_hesiod nsswitch module, which worked in previous releases, does not work at all in Ubuntu 16.04. Enabling it causes NULL pointer dereferences in calls such as getpwuid().
[Test Case]
# sed -i 's/passwd: *compat/& hesiod/' /etc/nsswitch.conf
# cat > /etc/hesiod.conf <<EOF
lhs=.ns
rhs=.athena.mit.edu
EOF
# id andersk
Segmentation fault (core dumped)
Expected output: uid=39270(andersk) gid=101(…) groups=101(…).
[Regression Potential]
I wrote a 6-line patch that conditionalizes an errant res_nclose call. There is also a bigger upstream patch on the glibc 2.22 and 2.23 stable branches that entirely removes the unused abstraction that necessitated the res_nclose calls at all. Neither patch makes any changes outside of the glibc hesiod directory, which as of now is so thoroughly broken that there is nothing left to regress.

[Impact]
The nss_hesiod nsswitch module, which worked in previous releases, does not work at all in Ubuntu 16.04. Enabling it causes NULL pointer dereferences in calls such as getpwuid(). This will prevent any user logins from succeeding in our environment of hundreds of workstations, which in turn blocks us from upgrading from 14.04 to 16.04.
[Test Case]
# sed -i 's/passwd: *compat/& hesiod/' /etc/nsswitch.conf
# cat > /etc/hesiod.conf <<EOF
lhs=.ns
rhs=.athena.mit.edu
EOF
# id andersk
Segmentation fault (core dumped)
Expected output: uid=39270(andersk) gid=101(…) groups=101(…).
[Regression Potential]
I wrote a 6-line patch that conditionalizes an errant res_nclose call. There is also a bigger upstream patch on the glibc 2.22 and 2.23 stable branches that entirely removes the unused abstraction that necessitated the res_nclose calls at all. Neither patch makes any changes outside of the glibc hesiod directory, which as of now is so thoroughly broken that there is nothing left to regress.
