2019-07-23upstream rev 1.28: fix comment typo.Darren Tucker
2019-07-23Remove sys/cdefs.h include.Darren Tucker
It's not needed on -portable (that's handled by includes.h) and not all platforms have it.
2019-07-23Re-apply portability changes to current sha2.{c,h}.Darren Tucker
Rather than attempt to apply 14 years' worth of changes to OpenBSD's sha2 I imported the current versions directly then re-applied the portability changes. This also allowed re-syncing digest-libc.c against upstream.
2019-07-23Import current sha2.c and sha2.h from OpenBSD.Darren Tucker
These are not changed from their original state, the next commit will re-apply the portable changes.
2019-07-19fix SIGWINCH delivery of Solaris for mux sessionsDamien Miller
Remove PRIV_PROC_SESSION which was limiting ability to send SIGWINCH signals to other sessions. bz#3030; report and fix from Darren Moffat
2019-07-19Fix format string integer type in error message.Darren Tucker
2019-07-16Hook memmem compat code into build.Darren Tucker
This fixes builds on platforms that don't have it (at least old DragonFly, probably others).
2019-07-16Import memmem.c from OpenBSD.Darren Tucker
2019-07-08Move log.h include inside ifdefs.Darren Tucker
Fixes build on some other platforms that don't have va_list immediately available (eg NetBSD).
2019-07-08Include log.h for debug() and friends.Darren Tucker
Should fix some compiler warnings on IRIX (bz#3032).
2019-07-08remove realpath() compat replacementDamien Miller
We shipped a BSD implementation of realpath() because sftp-server depended on its behaviour. OpenBSD is now moving to a more strictly POSIX-compliant realpath(2), so sftp-server now unconditionally requires its own BSD-style realpath implementation. As such, there is no need to carry another independant implementation in openbsd-compat. ok dtucker@
2019-07-06Add prototype for strnlen to prevent warnings.Darren Tucker
2019-07-06Cast *ID types to unsigned long when printing.Darren Tucker
UID and GID types vary by platform so cast to u_long and use %lu when printing them to prevent warnings.
2019-07-06Add prototype for compat strndup.(bz#3032).Darren Tucker
2019-06-16Include stdio.h for vsnprintf.Darren Tucker
Patch from mforney at mforney.org.
2019-06-14upstream rev 1.27: fix integer overflow.Darren Tucker
Cast bitcount to u_in64_t before bit shifting to prevent integer overflow on 32bit platforms which cause incorrect results when adding a block >=512M in size. sha1 patch from ante84 at gmail.com via openssh github, sha2 with djm@, ok tedu@
2019-06-14upstream rev 1.25: add DEF_WEAK.Darren Tucker
Wrap blowfish, sha*, md5, and rmd160 so that internal calls go direct ok deraadt@
2019-06-14upstream rev 1.25: add sys/types.hDarren Tucker
2019-06-14upstream: Use explicit_bzero instead of memsetDarren Tucker
in hash Final and End functions. OK deraadt@ djm@
2019-06-08Always clean up before and after utimensat test.Darren Tucker
2019-06-07Update utimensat test.Darren Tucker
POSIX specifies that when given a symlink, AT_SYMLINK_NOFOLLOW should update the symlink and not the destination. The compat code doesn't have a way to do this, so where possible it fails instead of following a symlink when explicitly asked not to. Instead of checking for an explicit failure, check that it does not update the destination, which both the real and compat implmentations should honour. Inspired by github pull req #125 from chutzpah at gentoo.org.
2019-04-26Don't install duplicate STREAMS modules on SolarisDarren Tucker
Check if STREAMS modules are already installed on pty before installing since when compiling with XPG>=4 they will likely be installed already. Prevents hangs and duplicate lines on the terminal. bz#2945 and bz#2998, patch from djm@
2019-04-03Remove "struct ssh" from sys_auth_record_login.Darren Tucker
It's not needed, and is not available from the call site in loginrec.c Should only affect AIX, spotted by Kevin Brott.
2019-04-02Adapt custom_failed_login to new prototype.Darren Tucker
Spotted by Kevin Brott.
2019-03-31Only use O_NOFOLLOW in fchownat and fchmodat if definedTim Rice
2019-03-28Only use O_NOFOLLOW in utimensat if defined.Darren Tucker
Fixes build on systems that don't have it (Solaris <=9) Found by Tom G. Christensen.
2019-03-13Replace alloca with xcalloc.Darren Tucker
The latter checks for memory exhaustion and integer overflow and may be at a less predictable place. Sanity check by vinschen at redhat.com, ok djm@
2019-03-12Use Cygwin-specific matching only for users+groups.Darren Tucker
Patch from vinschen at redhat.com, updated a little by me.
2019-02-22Cygwin: implement case-insensitive Unicode user and group name matchingCorinna Vinschen
The previous revert enabled case-insensitive user names again. This patch implements the case-insensitive user and group name matching. To allow Unicode chars, implement the matcher using wchar_t chars in Cygwin-specific code. Keep the generic code changes as small as possible. Cygwin: implement case-insensitive Unicode user and group name matching Signed-off-by: Corinna Vinschen <vinschen@redhat.com>
2019-02-22Revert unintended parts of previous commit.Darren Tucker
2019-02-22Revert "[auth.c] On Cygwin, refuse usernames that have differences in case"Corinna Vinschen
This reverts commit acc9b29486dfd649dfda474e5c1a03b317449f1c. Signed-off-by: Corinna Vinschen <vinschen@redhat.com>
2019-01-24Also undef SIMPLEQ_FOREACH_SAFE.Darren Tucker
Prevents macro redefinition warning on at least NetBSD 6.1.
2019-01-20remove vestiges of old packet API from loginrec.cDamien Miller
2019-01-18Add minimal fchownat and fchmodat implementations.Darren Tucker
Fixes builds on at least OS X Lion, NetBSD 6 and Solaris 10.
2019-01-18Add a minimal implementation of utimensat().Darren Tucker
Some systems (eg older OS X) do not have utimensat, so provide minimal implementation in compat layer. Fixes build on at least El Capitan.
2018-11-25Include stdio.h for FILE if needed.Darren Tucker
2018-11-25Reverse order of OpenSSL init functions.Darren Tucker
Try the new init function (OPENSSL_init_crypto) before falling back to the old one (OpenSSL_add_all_algorithms).
2018-11-23refactor libcrypto initialisationDamien Miller
Don't call OpenSSL_add_all_algorithms() unless OpenSSL actually supports it. Move all libcrypto initialisation to a single function, and call that from seed_rng() that is called early in each tool's main(). Prompted by patch from Rosen Penev
2018-11-16Test for OPENSSL_init_crypto before using.Darren Tucker
Check for the presence of OPENSSL_init_crypto and all the flags we want before trying to use it (bz#2931).
2018-11-16Fix check for OpenSSL 1.0.1 exactly.Darren Tucker
Both INSTALL and configure.ac claim OpenSSL >= 1.0.1 is supported; fix compile-time check for 1.0.1 to match.
2018-11-09fix compilation with openssl built without ECCEneas U de Queiroz
ECDSA code in openssh-compat.h and libressl-api-compat.c needs to be guarded by OPENSSL_HAS_ECC Signed-off-by: Eneas U de Queiroz <cote2004-github@yahoo.com>
2018-10-28Update check for minimum OpenSSL version.Darren Tucker
2018-10-28Use detected version functions in openssl compat.Darren Tucker
Use detected functions in compat layer instead of guessing based on versions. Really fixes builds with LibreSSL, not just configure.
2018-10-26fix builds on OpenSSL <= 1.0.xDamien Miller
I thought OpenSSL 1.0.x offered the new-style OpenSSL_version_num() API to obtain version number, but they don't.
2018-10-23fix compile for openssl 1.0.x w/ --with-ssl-engineDamien Miller
bz#2921, patch from cotequeiroz
2018-10-17unbreak compilation with --with-ssl-engineDamien Miller
Missing last argument to OPENSSL_init_crypto()
2018-10-16Avoid deprecated OPENSSL_config when using 1.1.xDamien Miller
OpenSSL 1.1.x soft-deprecated OPENSSL_config in favour of OPENSSL_init_crypto; pointed out by Jakub Jelen
2018-10-12Don't avoid our *sprintf replacements.Darren Tucker
Don't let systems with broken printf(3) avoid our replacements via asprintf(3)/vasprintf(3) calling libc internally. From djm@
2018-10-11check for NULL return from shadow_pw()Damien Miller
probably unreachable on this platform; pointed out by coolbugcheckers AT gmail.com
2018-10-10in pick_salt() avoid dereference of NULL passwordsDamien Miller
Apparently some NIS implementations can leave pw->pw_passwd (or the shadow equivalent) NULL. bz#2909; based on patch from Todd Eigenschink
