Bug #17162: Dir['**/*'] : stack smashing detected when listing big amount of directories

• Status: Closed
• Assignee: -
• Target version: -
• ruby -v: ruby 2.6.6p146 (2020-03-31 revision 67876) [x64-mingw32]
• Backport: 2.5: UNKNOWN, 2.6: UNKNOWN, 2.7: UNKNOWN

[kawsay (Clément Coquille)]

When I try to recursively list directories, the instructions returns an error "*** stack smashing detected ***" / "[BUG] Illegal instruction".
Error only happens when I try to list a big amount of directories.

Specificity:

• irb
• WSL / Start Command Prompt With Ruby (logged as domain administrator)
• remote drive mapped through "net use Z: \remote_storage"

Log:

2:\>irb
irb(main):001:0> Dir['**/*']                                                                                                                 *** stack smashing detected ***:  terminated

[jeremyevans0 (Jeremy Evans)]

One possible approach to avoiding the stack smash is to limit the recursion allowed during directory globbing. Here's a simple approach that does that: https://github.com/jeremyevans/ruby/commit/29edc847b991bb59185b15c16988bc8004299c16

Unfortunately, this simple approach has some disadvantages:

• May artificially limit recursion (32 levels may not be enough)
• Doesn't allow a user to specify a recursion level via a keyword argument
• May leak memory in failure case

If other committers are in favor of this approach despite the limitations, I can submit a pull request for it.

[kawsay (Clément Coquille)]

Here's a repository with 2 scripts that might help debugging.

• one to create a lot of directories & sub-directories
• another to clear newly created directories

https://gitlab.com/kawsay/ruby-bug-17162

Sadly I haven't got a lot of time to consecrate to this, nevertheless I'll keep you updated if I manage to recreate the bug on a test environment

[nobu (Nobuyoshi Nakada)]

Although I couldn't reproduce this issue even with 68 levels (exceeded the NTFS limit at that time), does this help?

Mistaken.
