This patchset fixes a crash caused by a too small MTU carried in the activate msg. Note that as such malicious packet does not exist in the normal env, the fix won't break any application
The 1st patch introduces a function to calculate the minimum MTU for the bearer, and the 2nd patch fixes the crash with this helper. While at it, the 3rd patch fixes the udp bearer mtu update by netlink with this helper. Xin Long (3): tipc: add tipc_bearer_min_mtu to calculate min mtu tipc: do not update mtu if msg_max is too small in mtu negotiation tipc: check the bearer min mtu properly when setting it by netlink net/tipc/bearer.c | 17 +++++++++++++++-- net/tipc/bearer.h | 3 +++ net/tipc/link.c | 9 ++++++--- net/tipc/udp_media.c | 5 +++-- 4 files changed, 27 insertions(+), 7 deletions(-) -- 2.39.1 _______________________________________________ tipc-discussion mailing list tipc-discussion@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/tipc-discussion
