Syscall Sandbox Termination

Rspigler commented at 4:49 pm on March 11, 2022: contributor

I was testing v23.0rc2 compiled.

./configure --without-miniupnpc --without-natpmp --enable-hardening --without-bdb --with-qrencode --with-zmq --with-sqlite=yes --disable-external-signer

bitcoin.conf:

assumevalid=0 blockfilterindex=1 coinstatsindex=1 dbcache=1000 prune=0 sandbox=log-and-abort txindex=1 cjdnsreachable=1 discover=1 i2psam=127.0.0.1:7656 listen=1 listenonion=1 networkactive=1 peerblockfilters=1 proxy=127.0.0.1:9050 addresstype=bech32m avoidpartialspends=1 changetype=bech32m maxapsfee=0.001 walletrbf=1 shrinkdebugfile=1

I deleted my data directory (/home/user/.bitcoin) to start a fresh download of the blockchain to test any errors. Ran out of space, and after deleting more and trying to start bitcoin-qt again:

ERROR: The syscall “linkat” (syscall number 265) is not allowed by the syscall sandbox in thread “main”. Please report. terminate called without an active exception Aborted

and in debug.log:

This was done on a Qubes 4.0 machine in a Debian 11 VM.
