[tor/maint-0.2.4] Avoid free()ing from an mmap on corrupted microdesc cache
by nickm＠torproject.org 17 Dec '13

17 Dec '13

commit d8cfa2ef4e6d57f6dd4a33e5b3cfb1a2a12fc4be Author: Nick Mathewson <nickm(a)torproject.org> Date: Mon Dec 16 13:00:15 2013 -0500 Avoid free()ing from an mmap on corrupted microdesc cache The 'body' field of a microdesc_t holds a strdup()'d value if the microdesc's saved_location field is SAVED_IN_JOURNAL or SAVED_NOWHERE, and holds a pointer to the middle of an mmap if the microdesc is SAVED_IN_CACHE. But we weren't setting that field until a while after we parsed the microdescriptor, which left an interval where microdesc_free() would try to free() the middle of the mmap(). This patch also includes a regression test. This is a fix for #10409; bugfix on 0.2.2.6-alpha. --- changes/bug10409 | 3 +++ src/or/dirvote.c | 3 ++- src/or/microdesc.c | 3 +-- src/or/routerparse.c | 13 ++++++++++--- src/or/routerparse.h | 2 +- src/test/test_microdesc.c | 45 +++++++++++++++++++++++++++++++++++++++++++++ 6 files changed, 62 insertions(+), 7 deletions(-) diff --git a/changes/bug10409 b/changes/bug10409 new file mode 100644 index 0000000..5ef5ae2 --- /dev/null +++ b/changes/bug10409 @@ -0,0 +1,3 @@ + o Minor bugfixes: + - Avoid a crash bug when starting with a corrupted microdescriptor + cache file.
