wallet: Duplicate wallets crash bitcoin core #16776

issue oxagast openend this issue on September 1, 2019

    Opening two of the same wallet (tested in v0.18.0 of bitcoin-qt 64 bit) will cause a database collision, and will crash the program.

    [marshall@likon] {21:21} [~] $ bitcoin-0.18.0/bin/bitcoin-qt terminate called after throwing an instance of 'std::runtime_error' what(): BerkeleyBatch: Can't open database 8204388-wallet.dat (duplicates fileid 8b1c090000000800e25686350000000000000000 from 1352491-wallet.dat) Aborted (core dumped)

    I have been able to reproduce the issue by importing two of the same wallet (with different filenames).

  2. fanquake added the label Wallet on Sep 1, 2019

    How are you loading the wallets?
  4. oxagast commented at 2:05 am on September 1, 2019: none
    File -> Open Wallet -> 8204388-wallet.dat then File -> Open Wallet -> 1352491-wallet.dat. Click the second one (which is a duplicate of the first wallet) and the GUI crashes.

    Here’s a backtrace.

    Is this a bug report or feature request? Be reminded that Bitcoin Core can’t open two wallets with the same file id at the same time.

    @MarcoFalke Perhaps I’m misunderstanding something here but if the user is able to achieve a core dump from the UI then we’re not handling this error condition in a very user friendly way?

    It appears this is only an issue with the GUI, not with the daemon
  17. promag commented at 1:44 am on September 6, 2019: member

    No, it also affects the daemon. For instance, create copies of the default wallet and then

    0src/bitcoind -regtest -debug -wallet=wallet2.dat -wallet=wallet3.dat

    I think CWallet::CreateWalletFromFile should catch the exception, WDYT?

    BTW, the exception comes from CWallet::CreateWalletFromFile -> BerkeleyBatch::BerkeleyBatch -> CheckUniqueFileid.

    Thanks @promag. Adjusted title again
  21. promag commented at 3:02 pm on September 6, 2019: member

    Turns out that catching the exception is not enough. For instance, with the following:

     0diff --git a/src/wallet/wallet.cpp b/src/wallet/wallet.cpp

    FWIW I ran across this issue today while testing #15204 (thanks @promag for the link here): #15204 (comment).
  23. GChuf commented at 10:07 am on October 14, 2019: contributor

    Was able to reproduce with 0.19.0.rc1 on Windows. Used same method as OP. In my debug.log, no info was given. When the error occurs, this is what I see (the debug log stops after this):

    02019-10-14T11:05:21Z init message: Loading wallet ...

22019-10-14T11:05:27Z Loading addresses from DNS seed dnsseed.emzy.de

    A window pops up which tells a bit more about the error. Screenshot_115

    Hi,

    First, I am not sure about the state of this bug and the PR related to it: #16923 , so, please, give me a hint if I am talking about things that I should not have touched.

    Anyway, I just experimented a bit, and would like to offer an alternative solution that uses the Hash160 Function to create hashes of given wallet files before the LoadWallet in load.cpp kicks in.

    This way every duplicate wallet file will be ignored, and logged.

    As shown here:

    duplicate_wallet

    Of course, it doesn’t have to be that way, as we could instead raise some error or warning message for the user. I am not sure which way is better, but regarding the fact that I don’t even know, if this experiment makes any sense, I’d rather avoid writing about the respective pros & cons.

    Here the link of the diff in my repo: https://github.com/brakmic/bitcoin/commit/e7606c8761f8e6c0381c7a5e46d9704ed71ce7e4

    There are two new functions, GetWalletHash and IsUniqueWalletHash as well as a vector for accepted wallet hashes. This vector gets cleared whenever UnloadWallets is called.

    Regards,

  26. sipa commented at 9:46 pm on March 19, 2020: member
    @brakmic I don’t think that will work, as it will only detect exactly identical wallet files, but not separate snapshots of the same wallet database at different points in time (i.e. it won’t detect loading a wallet and a restored earlier backup of the same wallet simultaneously).
