similar to: [PATCH] Correct checks for dup failure in guestfs_launch

As the start of work to add remote support, I'm taking a close look at the protocol layer in the library. These are some small cleanups. Rich.

These patches first make src/ warning free, and then turn on the strict warning options. 75 0001-build-suppress-an-ignored-write-return-value-warning.patch 38 0002-build-suppress-an-ignored-dup-return-value-warning.patch 27 0003-generator.ml-suppress-signed-unsigned-compare-warnin.patch 48 0004-build-don-t-perform-arithmetic-on-void-pointers.patch 30

I've been trying to cut down the size of openssh so I can run it on my Nokia 770. One thing which helps a fair amount (and will help even more when I get '-ffunction-sections -fdata-sections --gc-sections' working) is to have the option of compiling out privilege separation... Is it worth me tidying this up and trying to make it apply properly to the OpenBSD version? Does the openbsd

Get blktap2 running on pvops. This mainly adds eventfd support to the userland code. Based on some prior cleanup to tapdisk-queue and the server object. We had most of that in XenServer for a while, so I kept it stacked. 1. Clean up IPC and AIO init in tapdisk-server. [I think tapdisk-ipc in blktap2 is basically obsolete. Pending a later patch to remove it?] 2. Split tapdisk-queue into

I am running OpenSSH 2.9p1 on SunOS 5.7 w/4-24-2001 patch cluster. Like many other users I am seeing the hanging session on logout with background processes. This is a huge problem for me as I centrally manage 50+ machines with rdist across ssh. Instead of just complaining about the problem I thought I would put my CS degree to use and try to track down the problem myself. For starters,

This attempts to implement the idea proposed in https://www.redhat.com/archives/libguestfs/2010-April/msg00087.html The idea is that an externally managed QEMU (manual, or via libvirt) can boot the appliance kernel/initrd. libguestfs can then be just told of the UNIX domain socket associated with the guest daemon. An example based on guestfish. 1. Step one, find the appliance kernel/initrd

Thanks Rich. I have used libguestfs for several month. It worked perfectly before, the issue appears recently. I am trying guestfs_set_backend (g, "direct").

Hi, We recently upgraded OpenSSH from 7.5p1 to 8.0p1, and received a report that there was a behavioral differences where the ssh session did not disconnect after a remote background command execution. For example, "ssh user at example.com 'tail -f /var/xxx &' After looking at the debug logs and comparing the code, it seems there was a bug in the portable version during the

v1 was here: https://www.redhat.com/archives/libguestfs/2013-August/msg00005.html This now works, to some extent. The main problem now is that devices are named /dev/ubd[a-] which of course confuses everything. I'm thinking it may be easier to add a udev rule to rename them. Rich.

This is a User-Mode Linux backend for libguestfs. You can select it by doing: export LIBGUESTFS_BACKEND=uml export LIBGUESTFS_QEMU=/path/to/vmlinux Note we're reusing the 'qemu' variable in the handle for convenience. QEmu is not involved when using the UML backend. This almost works. UML itself crashes when the daemon tries to connect to the serial port. I suspect it's

Hi OpenSSH developers, I am using openSSH (now 2.9.9p2, but prob occurs in 2.9p2 also) to execute commands on a remote machine which outputs data to stdout then pipes it to another invocation of ssh which connects back to the first machine in the same way, where it starts a program to read and store the output from the command on the second machine. I am using the "command" option in

Thanks Rich for you quick reply.

This patch series is just FYI at the moment. However it does pass the tests. The daemon is a self-contained program. We don't need to write it all in C. Writing parts of it in OCaml would make it simpler and less error-prone. In particular if the daemon was written in a more sane programming language then we could move the inspection code to run entirely inside the appliance, which would

I found this useful when looking at where the time goes during guestfs_launch, and in fact using this I've reduced the launch time from around 12 seconds on my machine to 7 or 8 seconds.
