Tags: 1.0.1f-1ubuntu1
* Merge with Debian, remaining changes.
- debian/libssl1.0.0.postinst:
+ Display a system restart required notification on libssl1.0.0
upgrade on servers.
+ Use a different priority for libssl1.0.0/restart-services depending
on whether a desktop, or server dist-upgrade is being performed.
- debian/{libssl1.0.0-udeb.dirs, control, rules}: Create
libssl1.0.0-udeb, for the benefit of wget-udeb (no wget-udeb package
in Debian).
- debian/{libcrypto1.0.0-udeb.dirs, libssl1.0.0.dirs, libssl1.0.0.files,
rules}: Move runtime libraries to /lib, for the benefit of
wpasupplicant.
- debian/patches/perlpath-quilt.patch: Don't change perl #! paths under
.pc.
- debian/rules:
+ Don't run 'make test' when cross-building.
+ Use host compiler when cross-building. Patch from Neil Williams.
+ Don't build for processors no longer supported: i586 (on i386)
+ Fix Makefile to properly clean up libs/ dirs in clean target.
+ Replace duplicate files in the doc directory with symlinks.
- debian/control: Mark Debian Vcs-* as XS-Debian-Vcs-*
- debian/patches/ubuntu_deb676533_arm_asm.patch: Enable arm assembly
code.
- debian/rules: Enable optimized 64bit elliptic curve code contributed
by Google.
* Dropped changes:
- debian/patches/arm64-support: included in debian-targets.patch
- debian/patches/no_default_rdrand.patch: upstream
- debian/patches/openssl-1.0.1e-env-zlib.patch: zlib is now completely
disabled in debian/rules
- debian/libssl1.0.0.postinst:
+ Display a system restart required notification on libssl1.0.0
upgrade on servers.
+ Use a different priority for libssl1.0.0/restart-services depending
on whether a desktop, or server dist-upgrade is being performed.

1536

1537
* assumed that the server has better information about which protocol
1538
* a client should use.

1540
* 4) If the client doesn't support any of the server's advertised
1541
* protocols, then this is treated the same as case 2.

*
1543
* It returns either
1544
