git daemon's interpolated paths didn't support IPv6. Every IPv6 address was being converted to `0.0.0.0'. Fix this by replacing inet_ntop(3) with the protocol agnostic getnameinfo(3) API. Signed-off-by: Benjamin Kramer <redacted> --- With this patch we'll have colons in the per-IP directories for IPv6 addresses. Creating files with a : in the name fails on some OSes (e.g. Windows). Is this OK for git or do we need to special case IPv6 addresses? daemon.c | 8 +++----- 1 files changed, 3 insertions(+), 5 deletions(-)
