Results of lsof on each kernel
Update: The problem also exists on kernel-2.6.6-1.427 and stock 2.6.7-rc3. Again, stock 2.6.6 works fine. mass update for old bugs: Is this still a problem with the 2.6.9 based update kernel ? mass update for old bugs: Is this still a problem with the 2.6.9 based update kernel ? I can no longer reproduce the problem with 2.6.9 on FC 3. Appears either the kernel or the FC upgrade fixed this. |
Description of problem: When you run "lsof" on kernel-2.6.5-1.358 after upgrading an RPM containing shared libraries that were in use, it doesn't show the libraries that were replaced as unlinked mapped files ("DEL"); instead it displays them as regular files ("REG"). This problem does not exist when lsof is run on a stock 2.6.6 kernel. Version-Release number of selected component (if applicable): lsof-4.68-2 How reproducible: Always Steps to Reproduce: 1. See who's using libk5crypto.so.3.0. # lsof | fgrep /usr/lib/libk5crypto.so.3.0 2. Upgrade the krb5-* packages to a new version. # rpm -Fvh krb5-{libs,devel}-1.3.3-7.i386.rpm 3. Immediately after upgrading the shared libraries, again see who's using libk5crypto.so.3.0. # lsof | fgrep /usr/lib/libk5crypto.so.3.0 Actual Results: With kernel-2.6.5-1.358, the second lsof prints "REG" in the type column. This is wrong since the file was unlinked/replaced, and the daemons using the file were never restarted. Expected Results: With a stock 2.6.6 kernel, the second lsof prints "DEL" in the type column, indicating an unlinked mapped file. This is correct.
