Created attachment 2074068 [details] Fix SEGV in sec_tcp_conn_read_callback Description of problem: SEGV in sec_tcp_conn_read_callback due to attempt to read from freed structure Version-Release number of selected component (if applicable): 3.5.4 How reproducible: Run amcheck with a disklist that specifies a host that's down. Steps to Reproduce: 1. As per above 2. 3. Actual results: amcheck aborts with SEGV Expected results: amcheck reports EOF on read and completes Additional info: This has been around since Fed38 --- see closed bug 2192380. The problem is this loop statement: for (reader_callbacks = rc->reader_callbacks; reader_callbacks != NULL; reader_callbacks = reader_callbacks->next) { The loop executes the callback, which can remove itself from the callbacks list. By the time the loop continuation executes, reader_callbacks may well be freed and reused, resulting in a SEGV. The attachment fixes the SEGV. Builds on Fed41 from amanda-3.5.4-10.fc41.srcrpm, (i.e., amanda git tag tag-community-3.5.4 plus patches in the srcrpm) plus this patch and two more that I'll try to add. Compiler warnings are a bit frightening, but runs ok for my simple use case.
