Attempting to run cmake in vboxvfs shared folder cause cmake core dump and vboxvfs filesystem hang forever

[ae_der]

Attempting to run cmake in vboxvfs shared folder cause cmake core dump and vboxvfs filesystem hang forever.

Configuration: Windows host machine, freebsd 11.1-release 64_x86 guest machine: FreeBSD freebsd64 11.1-RELEASE-p10 FreeBSD 11.1-RELEASE-p10 #0: Tue May 8 05:21:56 UTC 2018 root@…:/usr/obj/usr/src/sys/GENERIC amd64

Windows folder d:/home mounted as /home/der under guest mackine:

Everything works fine, until I attempted to run cmake over some sources in /home/der/... tree:

[der@freebsd64 ~]$ [der@freebsd64 ~]$ cd cts/gen/utils/konfig/konfig-1.0cur/impl/ [der@freebsd64 ~/cts/gen/utils/konfig/konfig-1.0cur/impl]$ [der@freebsd64 ~/cts/gen/utils/konfig/konfig-1.0cur/impl]$ mkdir build mkdir: build: File exists [der@freebsd64 ~/cts/gen/utils/konfig/konfig-1.0cur/impl]$ cd build [der@freebsd64 ~/cts/gen/utils/konfig/konfig-1.0cur/impl/build]$ ls cmake.core [der@freebsd64 ~/cts/gen/utils/konfig/konfig-1.0cur/impl/build]$ rm cmake.core [der@freebsd64 ~/cts/gen/utils/konfig/konfig-1.0cur/impl/build]$ [der@freebsd64 ~/cts/gen/utils/konfig/konfig-1.0cur/impl/build]$ [der@freebsd64 ~/cts/gen/utils/konfig/konfig-1.0cur/impl/build]$ cmake ../src/ Assertion failed: (cmSystemTools::FileExists(currentStart, true)), function Configure, file /wrkdirs/usr/ports/devel/cmake/work/cmake-3.11.4/Source/cmMakefile.cxx, line 1414.

core dump was created,

[der@freebsd64 ~/cts/gen/utils/konfig/konfig-1.0cur/impl/build]$ ls -la total 10 drwxrwxrwx 1 der der 0 Jul 27 14:27 . drwxrwxrwx 1 der der 0 Jul 27 13:56 .. -rwxrwxrwx 1 der der 5402624 Jul 27 14:27 cmake.core

but attempts to change to parent directory failed:

[der@freebsd64 ~/cts/gen/utils/konfig/konfig-1.0cur/impl/build]$ cd .. cd: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory

After that, filesystem become unstable:

[der@freebsd64 ~]$ [der@freebsd64 ~]$ [der@freebsd64 ~]$ pwd /home/der [der@freebsd64 ~]$ ls cts proba test [der@freebsd64 ~]$ cd cts/ [der@freebsd64 ~/cts]$ ls gen libs mpcgs utils internal MPC_EL_Ru uso [der@freebsd64 ~/cts]$ [der@freebsd64 ~/cts]$ ls gen ls: gen: No such file or directory [der@freebsd64 ~/cts]$ ls gen libs mpcgs utils internal MPC_EL_Ru uso [der@freebsd64 ~/cts]$ cd gen -bash: cd: gen: No such file or directory [der@freebsd64 ~/cts]$ [der@freebsd64 ~/cts]$ ls gen libs mpcgs utils internal MPC_EL_Ru uso [der@freebsd64 ~/cts]$ ls -l ls: gen: No such file or directory total 0 drwxrwxrwx 1 der der 0 Jul 27 13:53 internal drwxrwxrwx 1 der der 0 Jul 27 13:54 libs drwxrwxrwx 1 der der 0 Jul 27 13:54 MPC_EL_Ru drwxrwxrwx 1 der der 0 Jul 27 13:53 mpcgs drwxrwxrwx 1 der der 0 Jul 27 13:54 uso drwxrwxrwx 1 der der 0 Jul 27 13:53 utils [der@freebsd64 ~/cts]$

As you can see, ls can see gen folder, and ls -l can't.

If I try to reboot host machine, it hangs forever.

Of course, attempt to run cmake in non-shared folder succeed.

The FreeBSD VBox shared folder driver is not officially supported by VirtualBox but a FreeBSD community effort, so we can't investigate any reports unfortunately.
