- add a flag to request chroot for the process, which is done only as very last (before chdir) operation before exec'ing the process in the child: this avoids using CHROOT_IN & CHROOT_OUT around command* invocations, and reduces the code spent in chroot mode - add failure checks for dup2 and open done in child, not proceeding to executing the process if they fail - open /dev/null

Improve readability of commandrvf() by replacing bare int values for file descriptors with their symbolic names STD{IN,OUT,ERR}_FILENO. Also add PIPE_READ and PIPE_WRITE for referencing relevant ends of a pipe. --- daemon/guestfsd.c | 79 +++++++++++++++++++++++++++++-------------------------- 1 file changed, 42 insertions(+), 37 deletions(-) diff --git a/daemon/guestfsd.c b/daemon/guestfsd.c

Currently we are unable to properly run guestfsd (the daemon) under valgrind. Attempts to run valgrind inside the appliance have not been successful (see patch 1/7). However we desperately need better valgrind coverage of the daemon, particularly because it is doing a lot of complex parsing of program output. This has been a problem for a long time. A better way to attack this problem is to

This patch reworks how we start up LVM and lvmetad. It fixes the problem we had converting a guest which had a peculiar LVM configuration: https://bugzilla.redhat.com/show_bug.cgi?id=1581810#c14 However please note I have NOT yet tested it fully. Rich.

In v2: - Kernel command line parsing now moved to the appliance. - In the captive daemon test, the daemon cleanly shuts down on exit. - Add another btrfs test. Rich.

Simplify how we handle lvm.conf.

Wherever we had code which did: if (something_bad) { perror (...); exit (EXIT_FAILURE); } replace this with use of the error(3) function: if (something_bad) error (EXIT_FAILURE, errno, ...); The error(3) function is supplied by glibc, or by gnulib on platforms which don't have it, and is much more flexible than perror(3). Since we already use error(3), there seems to be

Quite a victory for Gnulib here. I was able to port a large part of the daemon just by adding some modules and fixing a few headers. The remaining issues which are *not* fixed are: * No chroot on Windows. * No sync(2) call. * No posix_fallocate call. * No futimes call. * No pread call. * No custom printf format specifiers. * Quite a few problems in guestfsd.c, eg. code to run external

Hi, this series update libguestfs to a recent gnulib version, so that we can use its new getprogname module, and solve altogether one of the porting issues (the need for 'program_name' by the error module of gnulib), and have a single way to get the name of the current program. A number of changes in tools mostly, although mechanical. Thanks, Pino Toscano (3): Update gnulib to latest

This patch series lets you run the daemon under valgrind. Many errors were found and fixed. With the complete series applied, valgrind doesn't show any errors.

v1 was here: https://www.redhat.com/archives/libguestfs/2020-February/msg00220.html This patch series is a little bit better. It's still a bit of a hack. The _real_ fix for this is outlined in the TODO file (see patch 1) but that requires a lot more work than we could do before 1.42 is released, unless we delay 1.42 for a lot longer. I'm hoping with this to have something which works

Hi ,all : thanks for helping me ! I am using libguestfs-1.28.1 on ubuntu 12.04 to manage vm disk created by KVM. I downloaded libguestfs-1.28.1.tar.gz ,and then executed (1) ./autogen.sh (2) ./configure (3) make (4) make check .there is the error. /usr/Libvmi/libguestfs-1.28.1/run --test guest-aux/make-fedora-img.pl md_create: feature 'mdadm' is not available in this

daemon.c does just a chroot, without chdir. The result is that pwd does not work correctly (it causes fs/dcache.c:prepend_unreachable() to add the unreachable string). A workaround is to add "cd /" before each sh command. ><fs> mount /dev/sda2 / ><fs> sh "cd / ; chroot / ; /bin/pwd" / ><fs> sh "/bin/pwd" (unreachable)/ ><fs> sh

Hi I`ve been trying this guestfs_mount_local api for quite a few days, but still can`t get over it. Now it seems to have enter the fuse loop but have some problems with 'mount'? and stops at guestfs_mount_local_run(g). Here`s corresponding code in the test program: ?? if(guestfs_mount_local(g,"/mnt/libg")==-1) exit(EXIT_FAILURE); else guestfs_mount_local_run(g); ?? Below is a
