[Libguestfs] libldm crashes in a linux-sandbox context
Hello,
I am using libguestfs in a Bazel's linux-sandbox environment[1].
When executing in that sandbox environment, I got frequent crashes.
Please find attached below the results of libguestfs-test-tool when
run into that linux-sandbox environment. The most relevant part seems
to be:
[ 0.797233] ldmtool[164]: segfault at 0 ip 0000564a892506a5 sp
00007fff8ee5b900 error 4 in ldmtool[564a8924e000+3000]
[ 0.798117] Code: 18 64 48 33 1c 25 28 00 00 00 75 5e 48 83 c4 28 5b 5d 41
5c 41 5d 41 5e 41 5f c3 66 2e 0f 1f 84 00 00 00 00 00 e8 db fd ff ff <4c>
8b 20 48 89 44 24 08 4c 89 e7 e8 0b e1 ff ff 45 31 c0 4c 89 e1
/init: line 154: 164 Segmentation fault ldmtool create all
So the root cause seems to be around libldm. This mailing list seems
to cover both libguestfs and libldm, so hopefully, I am at the right
place to ask :)
Needless to say, when run outside of the sandbox environment, no crash
were observed.

Any idea why that would be? I looked at the sandbox and that would run the qemu process as UID "nobody" (which might be 65534). However I don't understand why that would affect anything running on the new kernel inside the appliance.
