UPDATE TO THIS RELEASE IS STRONGLY ADVISED!

This release fixes two locally exploitable security issue, namely the followings:
https://security.freebsd.org/advisories/FreeBSD-SA-16:19.sendmsg.asc
https://security.freebsd.org/advisories/FreeBSD-SA-16:18.atkbd.asc

Other news in this release:

  • Backported a lot of smaller coverity issues from FreeBSD.
  • Introduced fully enabled PIE, RELRO and BIND_NOW in the base system.

If you encounter build failures due the PIEified base system, you could empty the /usr/obj directory
and retry the build. For more details please consult the ${SRCTOP}/UPDATING-HardenedBSD
file.

HBSD: add build instructions after PIEified base system
HBSD: fix SETFKEY FreeBSD kernel vulnerability
HBSD: fix sockargs FreeBSD kernel heap overflow

jkim (3):
Detect Clang to support AVX instructions on x86 platforms. Note head (OpenSSL 1.0.2 branch) has similar changes.
- Make libcrypto.so position independent on i386. - Enable linker error when libcrypto.so contains a relocation against text. - Add "Do not modify" comment to generated source files. - Set CC environment variable for Perl scripts to enable AVX instructions. - Update __FreeBSD_version to indicate libcrypto.so is position independent.
Hide OPENSSL_cpuid_setup and OPENSSL_ia32cap_P symbols from libcrypto.so. Note this is a direct commit because it is merged from OpenSSL upstream and head (OpenSSL 1.0.2 branch) already has the same change:

truckman (15):
HBSD MFC: Use strlcpy() instead of strncpy() to copy the string returned by setlocale() so that static analyzers know that the string is NUL terminated. This was causing a false positive in Coverity even though the longest string returned by setlocale() is ENCODING_LEN (31) and we are copying into a 64 byte buffer. This change is also a bit of an optimization since we don't need the strncpy() feature of padding the rest of the destination buffer with NUL characters.
HBSD MFC: Use strlcpy() instead of strncpy() when copying the encoding value to ensure that the destination is NUL terminated. Length truncation of one more character should not be an issue since encoding values that long are not supported by libc. The destination string is treated as a NUL terminated string, but it is only passed to strcmp() for comparison to a set of shorter, fixed length strings, so this is not a serious problem.
HBSD MFC: Use strlcpy() instead of strncpy() when copying date and subj to ensure that these are properly NUL terminated since they are passed to printf().
HBSD MFC: Avoid Coverity NUL termination warning about strncpy() by using memcpy() instead. It's probably a bit more optimal in this case anyway. [1]
HBSD MFC: If fchdir() fails, call err() instead of warn().
HBSD MFC: Use strlcpy() instead of strncpy() to ensure that qup->fsname is NUL terminated. Don't bother checking for truncation since the subsequent quota_read() should detect that and fail.
HBSD MFC: Use strlcpy() instead of strncpy() to ensure that ret->name is NUL terminated. The source and destination buffers are the same size and the source should be NUL terminated, but be paranoid.
HBSD MFC: Use strlcpy() instead of strncpy() to ensure that qf->fsname is NUL terminated. Don't bother checking for truncation since the subsequent stat() call should detect that and fail.
HBSD MFC: Simplify some overly complex code so that both humans and Coverity have a better chance of understanding it.
HBSD MFC: Declare line[] in the outermost scope of retrieve() instead of declaring it in an inner scope and then using it via a pointer in the outer scope.
HBSD MFC: Instead of ignoring the EEXIST from link(), unconditionally unlink the terget before calling link(). This should prevent links to an old copy of the file from being retained.
HBSD MFC: Always return either a dynamically allocated string or NULL from expand(). Never return the name parameter, which could be a the buf[] buffer which is allocated on the stack by getdeadletter() and which would then be used after getdeadletter() has returned.
HBSD MFC: Move a call to cam_freeccb() to avoid a use after free error and a later double free.
HBSD MFC: Properly compute the size argument to pass to malloc().
HBSD MFC: Another attempt at resolving CID 1305629. The test of cmd == -1 may make Coverity think that other negative values of cmd (used as an index) are possible. Testing < 0 is a more common idiom in any case.
