The script in the original attachment had the wrong path for cryptsetup. It had the path used when testing from the compiled sources. I should have done a diff. On my centrino notebook with F7 and cryptsetup-luks 1.0.3-4 the following works
fine:
PW=TESTING123
EF=encrypted_file
LP=`losetup -f`
losetup ${LP} /tmp/${EF}
echo ${PW} | cryptsetup luksOpen ${LP} ${EF}
cryptsetup luksClose ${EF}
losetup -d ${LP}
Can you check, whether you still have this problem?
I tested on the original hardware. Both FC6 and FC7 work properly. I looks like the bug has been cleared. |
Description of problem: When the following is executed in a script and the password is manually typed there is no error. EF=encrypted_file LP=`losetup -f` losetup ${LP} /tmp/${EF} cryptsetup luksOpen ${LP} ${EF} cryptsetup luksClose ${EF} losetup -d ${LP} When the following is executed in a script and the password is piped to cryptsetup an error occurs when the loop device is deleted (ioctl: LOOP_CLR_FD: Device or resource busy). Each failure leaves the loop device busy and unusable. PW=TESTING123 EF=encrypted_file LP=`losetup -f` losetup ${LP} /tmp/${EF} echo ${PW} | cryptsetup luksOpen ${LP} ${EF} cryptsetup luksClose ${EF} losetup -d ${LP} Version-Release number of selected component (if applicable): cryptsetup 1.0.3 How reproducible: Test script in attachment always fails on FC6. Test script in attachment never fails on FC5. Steps to Reproduce: With test_script.sh from attachment. 1. ./test_script.sh setup 2. ./test_script.sh pass - No error is produced. 3. ./test_script.sh fail - Produces error. Actual results: ./test_script.sh fail ioctl:LOOP_CLR_FD: Device or resource busy Expected results: No losetup -d error when password is piped to cryptsetup Additional info: I think this is a timing or race condition involving dm-crypt, the device mapper, and luks-cryptsetup. Since this fails on a 32-bit AMD system and a 64-bit AMD system, I believe the problem can be created fairly easily on comparable hardware. In any case adding a sleep(1) at the beginning of main() in cryptsetup.c that causes the problem to go away tells me something very bogus is going on somewhere.
