They would like to move away from static header + defines for class and permissions and instead use dynamic checks + at runtime that provide an answer which is dependent on the runtime + status of SELinux i.e. more dynamic. + + The following patch is a minimal change that moves us forward in + this direction. + + It does the following: + + * Stop checking for SELinux headers that define NSCD__SHMEMHOST. + Check only for the presence or absence of the library. + + * Don't encode the specific SELinux permission constants into a + table at build time, and instead use the symbolic name for the + permission as expected. + + * Lookup the "What do we do if we don't know this permission?" + policy and use that if we find SELinux's policy is older than + the glibc policy e.g. we make a request for a permission that + SELinux doesn't know about. + + * Lastly, translate the class and permission and then make + the permission check. This is done every time we lookup + a permission, and this is the expected way to use the API. + SELinux will optimize this for us, and we expect the network + latencies to hide these extra library calls. + + Tested on x86, x86-64, and via Fedora Rawhide since November 2013. + + See: + https://sourceware.org/ml/libc-alpha/2014-04/msg00179.html + +diff --git a/configure b/configure +index abefcdb..8b0b222 100755 +--- a/configure ++++ b/configure +@@ -7774,64 +7774,10 @@ else + have_selinux=no + fi + +- # See if we have the SELinux header with the NSCD permissions in it. +- if test x$have_selinux = xyes ; then +- { $as_echo "$as_me:$LINENO: checking for NSCD Flask permissions in selinux/av_permissions.h" >&5 +-$as_echo_n "checking for NSCD Flask permissions in selinux/av_permissions.h...

The backticks in the arithmetic +# epxression are evaluated by in a shell even if WRDE_NOCMD forbade +# command substitution. This allows an attacker to attempt to pass +# dangerous commands via constructs of the above form, and bypass +# the WRDE_NOCMD flag. This patch fixes this by checking for WRDE_NOCMD +# in exec_comm(), the only place that can execute a shell. All other +# checks for WRDE_NOCMD are superfluous and removed. +# +# We expand the testsuite and add 3 new regression tests of roughly +# the same form but with a couple of nested levels. +# +# On top of the 3 new tests we add fork validation to the WRDE_NOCMD +# testing. If any forks are detected during the execution of a wordexp() +# call with WRDE_NOCMD, the test is marked as failed. This is slightly +# heuristic since vfork might be used in the future, but it provides a +# higher level of assurance that no shells were executed as part of +# command substitution with WRDE_NOCMD in effect.

Again we have some odd side-effects when the ++ second response is NOTFOUND because we overwrite *errnop and ++ *h_errnop that means that a first answer of NOTFOUND might see ++ its *errnop and *h_errnop values altered.

The expectation here is that ++ it will have failed similarly e.g. configuration failure. ++ ++ [5] Testing this code is complicated by the fact that truncated ++ second response buffers might be returned as SUCCESS if the ++ first answer is a SUCCESS.

If one of these is a + referral, then the query fails, which is wrong. It should return at + least the one successful response. + + The fix has two parts. The first part makes the referral fall back to + the SERVFAIL path, which results in using the successful response. + There is a bug in that path however, due to which the second part is + necessary. The bug here is that if the first response is a failure + and the second succeeds, __libc_res_nsearch does not detect that and + assumes a failure. The case where the first response is a success and + the second fails, works correctly. + + This condition is produced by buggy routers, so here's a crude + interposable library that can simulate such a condition. The library + overrides the recvfrom syscall and modifies the header of the packet + received to reproduce this scenario. It has two key variables: + mod_packet and first_error. + + The mod_packet variable when set to 0, results in odd packets being + modified to be a referral. When set to 1, even packets are modified + to be a referral. + + The first_error causes the first response to be a failure so that a + domain-appended search is performed to test the second part of the + __libc_nsearch fix. + + The driver for this fix is a simple getaddrinfo program that does an + AF_UNSPEC query. I have omitted this since it should be easy to + implement. + + I have tested this on x86_64. + + The interceptor library source: + + /* Override recvfrom and modify the header of the first DNS response to make it + a referral and reproduce bz #845218.
