2000-01-22Don't allow the time to be set forward so far it will wrap and become negative,Todd C. Miller
thus allowing an attacker to bypass the next check below. The cutoff is 1 year before rollover occurs, so even if the attacker uses adjtime(2) to move the time past the cutoff, it will take a very long time to get to the wrap point. The actual check is tv_sec > INT_MAX - 365*24*60*60 because on 64 bit platforms tv_sec is 64 bits but time_t is 32 bits. This will need to be changed some time in the future when the size of time_t changes. Add a printf when a user tries to turn the clock backwards and securelevel > 1

1999-12-08bring in KAME IPv6 code, dated 19991208.Jun-ichiro itojun Hagino
replaces NRL IPv6 layer. reuses NRL pcb layer. no IPsec-on-v6 support. see sys/netinet6/{TODO,IMPLEMENTATION} for more details. GENERIC configuration should work fine as before. GENERIC.v6 works fine as well, but you'll need KAME userland tools to play with IPv6 (will be bringed into soon).

EWOULDBLOCK. turns out the two checking conditions were not the same, and a certain use of rsync uncovered the bug by chewing all available cpu time; fix from art

1999-10-14Fix for PR 871.cmetz
This fix is taken from BSD/OS (the file in question being BSD licensed). It continues to remove a datagram from a socket receive buffer even if there is an error on the copy-out, so as to leave the buffer in a reasonable state. Before, the kernel would stop in mid-receive if the copy-out failed, and the buffer's structural requirements would be violated (since the start of a datagram must be an address iff ). Note that if the user provides any invalid addresses as arguments to a recvmsg(), the datagram at the front of the buffer will be discarded. The more correct behavior would be not to remove this datagram if the arguments are invalid. Implementing this behavior requires a lot of significant changes, and socket receives are a critical path. Also included are two simple and fairly obvious fixes from the same source. If non-blocking I/O is set, it makes sure the receieve is non-blocking. It also fixes a slightly over-aggressive optimization.
