Jeśli znajdziesz błąd w ClamAV, sprawdź czy nie został już poprawiony w kodzie SVN .

Jeśli nie jest jeszcze naprawiony, odwiedź nasz system zgłaszania błędów .

Proszę nie zgłaszać błędów dotyczących oprogramowania pochodzenia zewnętrznego (np. porty, którymi nie zarządzamy bezpośrednio), ponieważ nie mamy nad nim kontroli. Zamiast tego, skontaktuj się z właściwymi autorami.

Przy zgłaszaniu błędu, powinieneś załączyć następujące informacje:

• Adres e-mail: działający adres e-mail, poprzez który developerzy będą mogli kontaktować się z Tobą w celu uzyskania dodatkowych informacji oraz powiadomić, gdy błąd zostanie poprawiony.

• Wersja ClamAV: wynik następującej komendy:

  clamscan -V

• System details: full specs of your system: e.g. output from:

  uname -mrsp

• Library versions: your libc and possibly zlib versions

• How to reproduce the problem: if the issue is reproducible only when scanning a specific file, attach it to the message. Don’t forget to encrypt it or you may cause damage to the mail servers between you and us! E.g.:

  zip -P virus -e file.zip file.ext

  The content of the file will be kept confidential. Alternatively if the file is too big to mail it, you can upload it to a password protected website and send us the URL and the credentials to access it.
• Backtrace of clamscan: if possible send us the backtrace obtained from gdb, the GNU Project Debugger.

Here are step by step instructions which will guide you through the process:

Assuming you get something like:

$ clamscan --some-options some_file
Segmentation fault

The first thing to do is having the kernel write a core dump. For bourne-like shells (e.g. bash):

$ ulimit -c unlimited

For C-like shells (e.g. tcsh):

> limit coredumpsize unlimited

Now you should see the core dumped message:

$ clamscan --some-options some_file
Segmentation fault (core dumped)

Looking at your current working directory should reveal a file named core.

The next step is to load the core file into gdb:

$ gdb -core=core --args clamscan --some-options some_file
(gdb)

You should now see the gdb prompt. Just use the bt command at the prompt to make gdb print a full backtrace.
Copy and paste it into the bug report. You can use the q command to leave gdb.

• Backtrace of clamd:

Use ps to get the PID of clamd (first number from the left):

$ ps -aux (or ps -elf on SysV)
clamav 24897 0.0 1.9 38032 10068 ? S Jan13 0:00 clamd

Attach gdb to the running process:

$ gdb /usr/sbin/clamd 24897

Replace 24897 with the pid of clamd and adjust the path of clamd. You should now get the gdb prompt, as:

(gdb)

If you want clamd to continue running, until a segmentation fault occurs for example, issue the continue gdb command, and wait for an error, at which point gdb will return to its prompt. bt will give a backtrace for the current thread. The command info threads will tell you how many threads there are. The command thread n will change to the specified thread, after which you can use the bt command again to get it’s backtrace. So, you basically want to do:

info threads to get the number of threads and their id numbers

For each thread do:

thread id_number
bt

Exit from gdb with the quit command. Reply y to the question about the program still running.

• Strace: optionally, if you think it can help, the output from strace (not covered here).

When in doubt always compile ClamAV from sources.
