...n key mode; gnome-terminal / xterm / dtterm starts sending the ESC O ... cursor key sequences. Now the problem seems to be that the xenconsole process opens the domain''s slave pty, and uses the init_term() function to configure the terminal for "raw" mode. init_term() uses a TCSAFLUSH ioctl to set the new terminal attributes, but that apparently flushes queued data (the" ESC [ ? 1 h" vt100 init sequence for switching to application mode) that is already waiting in the pty''s output queue. Why doesn''t xen.hg/tools/console/client/main.c use TCSANOW whe...

Hi, on my system (Linux 2.6.18.8 - ia64), if a domain write on the xencons before xenconsole is initialized the domain gets back what it wrote. This patch fixes this issue by making raw the pty slave very early. (I suppose it doesn''t happen with linux as a guest because it takes a little bit of time before writing to xencons).

https://bugzilla.redhat.com/show_bug.cgi?id=1842440 Patches 1 and 2 address fairly obvious bugs in how we handle reading passwords from stdin. There are other ways we may consider fixing these bugs: - Should password=- always open /dev/tty and ignore stdin entirely? - Should we make password=-0/-1/-2 work by skipping the close? Or perhaps reopen the file descriptors on /dev/null after

Hi, in the last weeks I've unsuccessfully tried to get Samba (2.0.5a) - Unix (Suse 6.2) password sync working. Maybe somebody can give me a hint, what's wrong. Enclosed you'll find additional information.

Part 2 fix for: https://bugzilla.redhat.com/show_bug.cgi?id=1842440 Actually this fix on its own should be sufficient, but probably we want the nbdkit fixes too. Note this uses actual OCaml 4.05 features! ("let open" and the Unix.tcgetattr functions). I checked that both features are available on RHEL 7's OCaml. Rich.

This is the previous 5/9 patch posted earlier today, split into reviewable chunks. This passes bisection with -x 'make && make check', but I didn't work very hard on the commit messages, so I refer you back to the original patch to explain how it works: https://www.redhat.com/archives/libguestfs/2020-March/msg00248.html Rich.

This is an incomplete port to Windows. Currently the server compiles and starts up successfully, but goes into an infinite loop when you connect to it. Nevertheless I think the approach is ready for feedback. This being Windows the changes go quite deep. Rich.

This creates libnbdkit.so as discussed in the following thread: https://www.redhat.com/archives/libguestfs/2020-March/thread.html#00203 test-delay-shutdown.sh fails for unclear reasons. This series starts by reverting "tests: Don't strand hung nbdkit processes" which is because several other tests fail randomly unless I revert this patch. I didn't investigate this yet so it
