0.9.45 (git HEAD): "Error mount bind ld.so.preload"

[thomasjfox]

Hello,

I've upgraded from firejail 0.9.42 to firejail 0.9.45 (git HEAD).

When I invoke "firejail --debug uudeview", it fails like this:

---

Create the new ld.so.preload file
Mount the new ld.so.preload file
Error mount bind ld.so.preload: fs_trace.c:73 fs_trace: No such file or directory
Error: cannot establish communication with the parent, exiting...

Problem occurs when running as root or as normal user.

strace output from "strace -ff firejail uudeview >strace.out 2>&1":

---

[pid 13968] open("/run/firejail/mnt/ld.so.preload", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 4
[pid 13968] fstat(4, {st_mode=S_IFREG|0644, st_size=0, ...}) = 0
[pid 13968] mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7f3f0d4be000
[pid 13968] fchmod(4, 0644) = 0
[pid 13968] fchown(4, 0, 0) = 0
[pid 13968] write(4, "/usr/lib64/firejail/libtracelog."..., 35) = 35
[pid 13968] close(4) = 0
[pid 13968] munmap(0x7f3f0d4be000, 4096) = 0

[pid 13968] mount("/run/firejail/mnt/ld.so.preload", "/etc/ld.so.preload", NULL, MS_BIND|MS_REC, NULL) = -1 ENOENT (No such file or directory)

It's odd that the creation of ld.so.preload worked
and then there's no file available when doing the mount.

I've inspected /run/firejail/mnt and there is indeed no ld.so.preload file.

"firejail --ignore=trace uudeview" works.

uudeview and firejail are both 64 bit, so it seems unrelated to issue #971.

Cheers,
Thomas
