christos 333e176687 - sprinkle const 
- remove unneeded casts
- use more mem*() instead of b*() funcs.
 2005-05-29 21:22:52 +00:00
martin 3cde73812d Fix typo, from C. Plasschaert in PR kern/30069. 2005-04-27 07:48:02 +00:00
christos d7ec95d370 factor out the interface queueing code into two functions. One used by 
the non point-to-point interfaces that has one queue, and one used by
the point to point interfaces that has two queues. No functional changes.
XXX: The ALTQ stuff makes the code ugly.
XXX: More cleanup to come

any NCP is UP.

martin 6f2d2eefc7 Rearange dead link detection slightly: 
As long as we receive data from the peer, don't worry. When we have not
received anything within the "max_noreceive" period, we start sending LCP
echo requests and count them, until we receive an answer (or some data)
or the "maxalive" count of not answered echo requests is reached.
All this is checked at a global 10 seconds interval for all interfaces.
The "max_noreceive" period and the "maxalive" count are configurable per
interface.
 2003-09-03 20:48:46 +00:00
martin 2951cb8e99 We should use IFQ_DEQUEUE to get packets from the send queue, not IF_DEQUEUE. 
Hopefully this will fix ALTQ for ISDN and PPPoE interfaces.

While there remove an unsued function which contained dubious code
(accessing interface queue internals w/o the proper macros).

itojun 8228c94987 don't call if_free_sadl() until very end of if_detach() logic. many of

martin 1caaa903fa If the peer did not answer LCP echo requests in-time, but we got user 
data through within the last LCP keepalive interval, do not count this
as a keepalive failure.

Addresses parts of kern/17723.

christos d64bbf607d Fix async map handling. Many thanks to Joerg Wunsch for the explanation. 2002-07-30 13:16:35 +00:00
christos 42f6b6f836 Patches from Frank Kardel: 
- length was one off in names and secrets.
- add win 98 kludge but we keep it disabled for now.
- setup the authorization bit early so that we don't end up doing ppp
  negotiations without authorization.
 2002-07-28 22:16:47 +00:00
christos 59d3d6c274 Don't throw away the name and the secret lengths. This eliminates all the 
strlen() calls, and there was a whole bunch of them.
 2002-07-28 19:54:47 +00:00
christos 450091b937 avoid modifying the buffers, by checking for matching lengths first. From 
Frank Kardel.
 2002-07-28 15:12:29 +00:00
christos ca989d9a38 Use strcmp() instead of memcmp() because if we get passed a 0 length name 
and secret, we'll authenticate successfully! While there, rename passwd to
secret so that code looks nicer.

itojun eee0912fd7 don't panic on invalid CONF_ACK from remote (in general, issueing panic 
on remote input is bad practice)

martin 75a925b327 "if (debug)" some log messages not signaling real errors but happening 
in normal operation.

martin 493d3dde20 Add support to query the peer for DNS addreses when negotiating IPCP. 
Add ioctls to retrieve the results.

While here remove a malloc()/free() of an unused buffer.
 2002-03-02 16:23:42 +00:00
martin 39764a5363 Use IF_IS_EMPTY and IFQ_IS_EMPTY instead of accessing queue members

Better range & sanity checking for ioctl arguments (thanks, Jaromir!)

martin 78ce6cb0f8 Initialize the activity timestamp when opening a connection. Only idle- 
timeout connection that made it to phase NETWORK yet. (For drivers using
the internal timeout mechanism; isdnd, that does the timeout handling for
ISDN drivers, still needs to be fixed.)

Thanks to Wolfgang Solfrank for finding this.

martin da249d7da1 Implement a retry counter for failed authorizations and limit it to 
a configurable maximum (default: 5).

Some ISPs shut down accounts (at least temporarily) after to many bad
retries. This hit me recently due to a stupid pilot error and the fast
retry rate.
 2002-01-07 10:49:02 +00:00
martin 45514531fd Implement an activity timestamp, recording the last time payload data 
passed through.

Implement optional idle timeout.

thorpej ce4f05c0a3 Fix LP64 printf format problem. 2002-01-05 19:26:44 +00:00
martin 99772f59c4 Move net/if_sppp.h to net/if_spppvar.h, create a new net/if_sppp.h 
containing the userland visible thinks (i.e. ioctl definitions).

Remove all (both) old ioctls, as they had a brain dead API and made keeping
binary compatibility more or less impossible.

Replace by several new ioctls. While there, remove any arbitrary limits
(resulting from the old, broken ioctls) and allow any length of names
and passwords.
