Current master fails to build if certain systemd functionality is not available at build time, daemon/journal.c has OPTGROUP_SD_JOURNAL_NOT_AVAILABLE at the end of the file. Is this a typo, what should be done in that case?

Re: [Libguestfs] 2 patches to make portablexdr useable in mingw

by Richard W.M. Jones

If you pass on something which can be applied to the portablexdr git repo, then I'll apply them. But portablexdr is obsolete for a reason - it's not been worked on for 4 years and needs a maintainer.

missing chdir before chroot in guestfsd

by Olaf Hering

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 "cd / ; /bin/pwd" / This untested change may fix it. =================== --- libguestfs-1.20.10.orig/daemon/guestfsd.c +++ libguestfs-1.20.10/daemon/guestfsd.c @@ -879,7 +879,11 @@ commandrvf (char **stdoutput, char **std close (stdin_fd[PIPE_READ]); close (stdin_fd[PIPE_WRITE]); - if (chroot (sysroot) == -1) { + if (chdir (sysroot) == -1) { + perror ("chdir"); + _exit (EXIT_FAILURE); + } + if (chroot (".") == -1) { perror ("chroot"); _exit (EXIT_FAILURE); } Olaf
