The underlying problem is that there are 2 zlib's in the kernel tree. One is in sys/cddl/contrib/opensolaris/uts/common/zmod/ and the other is sys/net/zlib.c. The real fix is to get rid of one of them and use the remaining one for all subsystems that want zlib. I agree that merging them is non-trivial because they are based on different versions of zlib (1.2.3 & 1.0.4, respectively) and the original files have been munged is different ways. (And there's a third inflate(9) based on unzip-5.12 in sys/kern/inflate.c, as well as another complete zlib-1.2.7 in lib/libz) --=20 Peter Jeremy --YZ5djTAD1cGYuMQK Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.19 (FreeBSD) iEYEARECAAYFAlAgUFsACgkQ/opHv/APuIdITACdFOcCILSaKfHRKUXW487HjUNI Q+gAoKFWWeN4IysmPXz/0j0aC2AJJvBV =8xM/ -----END PGP SIGNATURE----- --YZ5djTAD1cGYuMQK--
