pfil information, instead, struct protosw now contains a structure
which caontains list heads, etc. The per-protosw pfil struct is passed
to pfil_hook_get(), along with an in/out flag to get the head of the
relevant filter list. This has been done for only IPv4 and IPv6, at
present, with these patches only enabling filtering for IPPROTO_IP and
IPPROTO_IPV6, although it is possible to have tcp/udp, etc, dedicated
filters now also. The ipfilter code has been updated to only filter
IPv4 packets - next major release of ipfilter is required for ipv6.
the hack tries to respect ifa or ifp passed to RTM_ADD. However, the change
broke certain link-layers. They include:
- midway ethernet card (en*), which uses sockaddr_dl in gateway portion
to pass PVC information. with the patch, the gateway portion will be
overwritten by empty sockaddr_dl and PVC initialization will fail.
- IPv6, which can't set static ND table with the patch (ndp -s), for the
similar reason as above.
There may be improved hack coming soon, hope the new one does not break others.
Continue partial write(2) on signals (xwrite()).
Partial read(2) at a few places are also continued (xread()).
Add {read,write}_with_restart() hooks for porting on systems
which don't restart interrupted read()/write() calls.
Reviewed and discussed in tech-kern and tech-userlevel lists.
- there's no match against addresses on IFF_UP interface,
send icmp unreach if I'm router. drop it if I'm host.
Revised version of PR: 9387 from nrt@iij.ad.jp. Discussed with thorpej+nrt.
dev/vndvar.h or dev/ccdvar.h so that struct pool is always available
regardless of multiple inclusion. Actually, ccdconfig.c compiles without
this change but ...
per mount point, the way ``try to export and unexport an unnecessary
mount point later'' may leave unwanted information in the kernel, and
doesn't work if a mount point is default exported or publically exported.
To fix the race condtion, we need another way.
don't query the user for terminal type if the type is not `unknown'
2.) change this a little in both the csh and the [k]sh cases -- do call
tset(1) even if the terminal type is known (so that TERMCAP is set
properly, but don't have it query the user.
