2015-08-19Handle SELinux authorisation rolesManoj Srivastava
Rejected upstream due to discomfort with magic usernames; a better approach will need an SSH protocol change. In the meantime, this came from Debian's SELinux maintainer, so we'll keep it until we have something better. Bug: https://bugzilla.mindrot.org/show_bug.cgi?id=1641 Bug-Debian: http://bugs.debian.org/394795 Last-Update: 2015-08-19 Patch-Name: selinux-role.patch
2015-04-29upstream commitderaadt@openbsd.org
rename xrealloc() to xreallocarray() since it follows that form. ok djm
2015-01-16upstream commitderaadt@openbsd.org
Replace <sys/param.h> with <limits.h> and other less dirty headers where possible. Annotate <sys/param.h> lines with their current reasons. Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)
2015-01-15upstream commitdjm@openbsd.org
move authfd.c and its tentacles to the new buffer/key API; ok markus@
2014-12-22upstream commitdjm@openbsd.org
make internal handling of filename arguments of "none" more consistent with ssh. "none" arguments are now replaced with NULL when the configuration is finalised. Simplifies checking later on (just need to test not-NULL rather than that + strcmp) and cleans up some inconsistencies. ok markus@
