It should check to see if it's in-use (i.e. matches an existing PF state), if it is, it cycles sequentially through other ports until it finds a free one. However the check was being done with the state keys the wrong way round so it was never actually finding the state to be in-use. - switch the keys to correct this, avoiding random state collisions with nat. Fixes PR 6300 and problems reported by robert@ and viq. - check pf_get_sport() return code in pf_test(); if port allocation fails the packet should be dropped rather than sent out untranslated. Help/ok claudio@. Some additional changes to 1.12: - We also need to bzero() the key to zero padding, otherwise key won't match. - Collapse two if blocks into one with ||, since both conditions lead to the same processing. - Only naddr changes in the cycle, so move initialization of other fields above the cycle. - s/u_intXX_t/uintXX_t/g PR: kern/181690 Submitted by: Olivier Cochard-Labbé <olivier cochard.me> Sponsored by: Nginx, Inc. |
