2019-04-05second thoughts: leave README in placeDamien Miller
A number of contrib/* files refer to the existing README so let's leave it in place for release and add the new markdown version in parallel. I'll get rid of README after release.
2019-04-05Revert "rewrite README"Damien Miller
This reverts commit 9444d82678cb7781820da4d1c23b3c2b9fb1e12f.
2019-04-05rewrite READMEDamien Miller
Include basic build instructions and comments on commonly-used build- time flags, links to the manual pages and other resources. Now in Markdown format for better viewing on github, etc.

2019-03-14On Cygwin run sshd as SYSTEM where possible.Darren Tucker
Seteuid now creates user token using S4U. We don't create a token from scratch anymore, so we don't need the "Create a process token" privilege. The service can run under SYSTEM again... ...unless Cygwin is running on Windows Vista or Windows 7 in the WOW64 32 bit emulation layer. It turns out that WOW64 on these systems didn't implement MsV1_0 S4U Logon so we still need the fallback to NtCreateToken for these systems. Signed-off-by: Corinna Vinschen <vinschen@redhat.com>

2019-03-01upstream: Fix two race conditions in sshd relating to SIGHUP:djm@openbsd.org
1. Recently-forked child processes will briefly remain listening to listen_socks. If the main server sshd process completes its restart via execv() before these sockets are closed by the child processes then it can fail to listen at the desired addresses/ports and/or fail to restart. 2. When a SIGHUP is received, there may be forked child processes that are awaiting their reexecution state. If the main server sshd process restarts before passing this state, these child processes will yield errors and use a fallback path of reading the current sshd_config from the filesystem rather than use the one that sshd was started with. To fix both of these cases, we reuse the startup_pipes that are shared between the main server sshd and forked children. Previously this was used solely to implement tracking of pre-auth child processes for MaxStartups, but this extends the messaging over these pipes to include a child->parent message that the parent process is safe to restart. This message is sent from the child after it has completed its preliminaries: closing listen_socks and receiving its reexec state. bz#2953, reported by Michal Koutný; ok markus@ dtucker@ OpenBSD-Commit-ID: 7df09eacfa3ce13e9a7b1e9f17276ecc924d65ab

2019-02-24upstream: openssh-7.9 accidentally reused the server's algorithm listsdjm@openbsd.org
in the client for KEX, ciphers and MACs. The ciphers and MACs were identical between the client and server, but the error accidentially disabled the diffie-hellman-group-exchange-sha1 KEX method. This fixes the client code to use the correct method list, but because nobody complained, it also disables the diffie-hellman-group-exchange-sha1 KEX method.

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.
