2017-09-28abort in configure when only openssl-1.1.x foundDamien Miller
We don't support openssl-1.1.x yet (see multiple threads on the openssh-unix-dev@ mailing list for the reason), but previously ./configure would accept it and the compilation would subsequently fail. This makes ./configure display an explicit error message and abort. ok dtucker@
2017-09-27Check for and handle calloc(p, 0) = NULL.Darren Tucker
On some platforms (AIX, maybe others) allocating zero bytes of memory via the various *alloc functions returns NULL, which is permitted by the standards. Autoconf has some macros for detecting this (with the exception of calloc for some reason) so use these and if necessary activate shims for them. ok djm@

2017-09-22upstream commitmarkus@openbsd.org
Add 'reverse' dynamic forwarding which combines dynamic forwarding (-D) with remote forwarding (-R) where the remote-forwarded port expects SOCKS-requests. The SSH server code is unchanged and the parsing happens at the SSH clients side. Thus the full SOCKS-request is sent over the forwarded channel and the client parses c->output. Parsing happens in channel_before_prepare_select(), _before_ the select bitmask is computed in the pre[] handlers, but after network input processing in the post[] handlers. help and ok djm@ Upstream-ID: aa25a6a3851064f34fe719e0bf15656ad5a64b89

Make remote channel ID a u_int Previously we tracked the remote channel IDs in an int, but this is strictly incorrect: the wire protocol uses uint32 and there is nothing in-principle stopping a SSH implementation from sending, say, 0xffff0000. In practice everyone numbers their channels sequentially, so this has never been a problem. ok markus@ Upstream-ID: b9f4cd3dc53155b4a5c995c0adba7da760d03e73

refactor channels.c Move static state to a "struct ssh_channels" that is allocated at runtime and tracked as a member of struct ssh. Explicitly pass "struct ssh" to all channels functions. Replace use of the legacy packet APIs in channels.c. Rework sshd_config PermitOpen handling: previously the configuration parser would call directly into the channels layer. After the refactor this is not possible, as the channels structures are allocated at connection time and aren't available when the configuration is parsed. The server config parser now tracks PermitOpen itself and explicitly configures the channels code later. ok markus@ Upstream-ID: 11828f161656b965cc306576422613614bea2d8f

2017-09-08Fuzzer harnesses for sig verify and pubkey parsingDamien Miller
These are some basic clang libfuzzer harnesses for signature verification and public key parsing. Some assembly (metaphorical) required.
2017-09-08Give configure ability to set CFLAGS/LDFLAGS laterDamien Miller
Some CFLAGS/LDFLAGS may disrupt the configure script's operation, in particular santization and fuzzer options that break assumptions about memory and file descriptor dispositions. This adds two flags to configure --with-cflags-after and --with-ldflags-after that allow specifying additional compiler and linker options that are added to the resultant Makefiles but not used in the configure run itself. E.g. env CC=clang-3.9 ./configure \ --with-cflags-after=-fsantize=address \ --with-ldflags-after="-g -fsanitize=address"
