2000-03-03If we attempted reschedule two times without suceeding, uiomove will yield,Artur Grabowski
giving other processes a chance to run. A process feeding a huge buffer to {read,write}{,v} on a file that doesn't need to wait for I/O, could have hogged a lot of cpu in the kernel, blocking all userland activity. Based on a similiar fix in FreeBSD.
2000-03-03Keep track of the number of times we trigger a reschedule before theArtur Grabowski
context switch actually happens.
2000-03-03Use the LIST_FIRST macro to get the head of zombproc list.Artur Grabowski
2000-03-03Use LIST_ macros instead of internal field names to walk the allproc list.Artur Grabowski

2000-03-03Remove extraneous newline.Angelos D. Keromytis
2000-03-02New function: m_getptr(), takes as argument an mbuf chain and anAngelos D. Keromytis
offset, returns a pointer to them specific mbuf and the offset inside it that corresponds to the offset argument (so one can find where the n'th byte is in an mbuf).
2000-03-02Add an option DDB_SAFE_CONSOLE that defaults db_console to 1.Artur Grabowski
In many cases, setting db_console in /etc/rc is too late.

2000-02-18fix alignment problem in ancillary data (alpha).Jun-ichiro itojun Hagino
only ipv6 tools (which touches ancillary data) are affected. From: =?iso-8859-1?Q?G=F6ran_Bengtson?= <goeran@cdg.chalmers.se>
2000-02-15Add another argument to extent_alloc_subregion to allow specifing an offsetArtur Grabowski
to the alignment. rename the function to extent_alloc_subregion1 and add compatibility macros. From NetBSD.

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).
