newfs_lfs gives lfs_minfreeseg a value of 1/8 of the total segments on
the disk, based on rough empirical data, but this should be refined in
the future.
pull in just about all of the differences from the crypto-us telnet
suite (which includes Kerberos 4 and connection encryption support).
Also bring in the Kerberos 5 support from the Heimdal telnet, and
frob a little so that it can work with the non-Heimdal telnet suite.
There is still some work left to do, specifically:
- Add Heimdal's ticket forwarding support to the Berkeley Kerberos 4
module.
- Add connection encryption support to the Heimdal Kerberos 5
module. Hints on this can be taken from the MIT Kerberos 5
module which still exists in crypto-us.
However, even with the shortcomings listed above, this is a
better situation than using the stock Heimdal telnet suite,
which does not understand the IPSec policy stuff, and is also
based on much older code which contains bugs that we have already
fixed in the NetBSD sources.
* fix RATE{GET,PUT} under some situations when the client is slower than
the server (something i missed when migrating the rate limiting code
i wrote in ftp(1) to ftpd(8))
* document what units RATE{GET,PUT} use
adding support for Heimdal/KTH Kerberos where easy to do so. Eliminate
bsd.crypto.mk.
There is still a bunch more work to do, but crypto is now more-or-less
fully merged into the base NetBSD distribution.
* implement closedataconn() and use appropriately (including in mlsd())
* only put leading space in front of MLST output (not MLSD output)
* MLSD: only output pdir and cdir entries when the type fact is requested.
* change error code for giving MLSD a non-directory from 550 to 501
* remove MLSx Type fact support for UNIX.* for now; it's not standardised yet.
* do a check_login when MLSD and MLST are given no args
* detect & complain about null facts in OPTS MLST
* cache getgroups() at login instead of calling each time in fact_perm()
other mods:
* implement cprintf(); as per fprintf() but increments total_bytes{,_out}
* implement CPUTC(); as per putc() but increments total_bytes{,_out}
* implement base64_encode()
* fact_unique() display base64 encoding of dev_t and ino_t rather than
hex output; should scale if size of those changes
* change reply() so that a negative code acts as the initial line in a reply,
code == 0 prefixes the line with 4 spaces, and code > 0 works as before.
deprecate lreply(code, ) and lreply(0, ) in favour of reply(-code, ) and
reply(0, ) respectively.
* use cprintf() and CPUTC() appropriately (often instead of printf(),
lreply(-2, ) or lreply(-1, ).
now we actually account for the data sent by MLST and MLSD.
* remove DEBUG support for sending MLSD output to control connection instead
of data connection (my ftp client now supports MLSD :-)
* implement draft-ietf-ftpext-mlst-10 commands, especially MLST and MLSD.
we already supported SIZE and MDTM. add the appropriate FEAT output lines.
* migrate a lot of the command code from ftpcmd.y and ftpd.c to cmds.c
* make dataconn(), feat(), lookup(), opts() and sizecmd() public
* modify struct tab so that it has a `flags' instead of `implemented' element,
and remove the `hasopts' element. If flags == 1, the command is implemented.
if flags == 2, the command is implemented and takes options
* add macros ISDOTDIR(x) (is x ".") and ISDOTDOTDIR(x) (is x "..")
* modify lreply() so that lreply(-2, ...) just outputs the given info without
a prefix or trailing \r\n. this saves doing b = printf(); total_* += b;
* enhance statcmd(). still needs work in the LPRT status stuff.
* crank version
some unsatisfied references (most often when compiled without necessary
-Wl,-R), so check for that instead of causing null-dereference;
this way the code has a chance to cleanup after itself and report
the error to caller
Thanks to Jason Thorpe for helping fix this!
- ftp(1): treats IPv4 mapped destination as IPv4 peer, not native IPv6 peer.
this does not support network with SIIT translator.
- rshd(8)/rlogind(8): rejects accesses from IPv4 mapped peer, to avoid
possible abuse of IPv4 mapped addr (rshd/rlogind use source address-based
auth so it is important to check the condition).
