| H A D | db_command.c | diff 163909 Thu Nov 02 09:47:38 MST 2006 kib On trap while inside ddb, the trap handler calls kdb_reenter(), that longjmp to the default context. As result, "alltrace" command may be prematurely terminated (without error message). This is happens, for instance, when system is low on memory and referenced page in kernel-mode thread stack is swapped out. Protect "alltrace" against termination on trap by setting temporary kdb_jmpbuf context. Submitted by: Peter Holm |
