Depending on their definition in z/VM, virtual devices for z/VM VSWITCH or GuestLAN must be configured either in layer2 or in layer3 mode. If qeth detects a layer mismatch, device activation fails. Trying to recover from this error cannot help; thus scheduling a recovery should be avoided. In addition, since recovery is forbidden during online setting of a qeth device, existence of its network device is guaranteed for all dev_close() calls in qeth. The corresponding checks can be removed. Signed-off-by: NUrsula Braun <ursula.braun@de.ibm.com> Signed-off-by: NFrank Blaschka <frank.blaschka@de.ibm.com> Signed-off-by: NDavid S.

If HiperSockets Network Traffic Analyzer is switched off, but trace disabling fails somehow, the qeth driver does not switch off its promisc mode status.

Port commit 20deb48d16fdd07ce2fdc8d03ea317362217e085 from git://tipc.cslab.ericsson.net/pub/git/people/allan/tipc.git Part of the large effort I'm trying to help with getting all the downstreamed code from windriver forward ported to the upstream tree Origional commit message Restore check to filter out inadverdently received messages This patch reimplements a check that allows TIPC to discard messages that are not intended for it. This check was present in TIPC 1.5/1.6, but was removed by accident during the development of TIPC 1.7; it has now been updated to account for new features present in TIPC 1.7 and reinserted into TIPC. The main benefit of this check is to filter out messages arriving from orphaned link endpoints, which can arise when a node exits the network and then re-enters it with a different TIPC network address (i.e. <Z.C.N> value).

Remove htohl implementation from tipc I was working on forward porting the downstream commits for TIPC and ran accross this one: http://tipc.cslab.ericsson.net/cgi-bin/gitweb.cgi?p=people/allan/tipc.git;a=commitdiff;h=894279b9437b63cbb02405ad5b8e033b51e4e31e I was going to just take it, when I looked closer and noted what it was doing. This is basically a routine to byte swap fields of data in sent/received packets for tipc, dependent upon the receivers guessed endianness of the peer when a connection is established. Asside from just seeming silly to me, it appears to violate the latest RFC draft for tipc: http://tipc.sourceforge.net/doc/draft-spec-tipc-02.txt Which, according to section 4.2 and 4.3.3, requires that all fields of all commands be sent in network byte order. So instead of just taking this patch, instead I'm removing the htohl function and replacing the calls with calls to ntohl in the rx path and htonl in the send path. As part of this fix, I'm also changing the subscr_cancel function, which searches the list of subscribers, using a memcmp of the entire subscriber list, for the entry to tear down. unfortunately it memcmps the entire tipc_subscr structure which has several bits that are private to the local side, so nothing will ever match. section 5.2 of the draft spec indicates the <type,upper,lower> tuple should uniquely identify a subscriber, so convert subscr_cancel to just match on those fields (properly endian swapped). I've tested this using the tipc test suite, and its passed without issue. Signed-off-by: NNeil Horman <nhorman@tuxdriver.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

We added an automatic route cache rebuilding in commit 1080d709 but had to correct few bugs. One of the assumption of original patch, was that entries where kept sorted in a given way. This assumption is known to be wrong (commit 1ddbcb00 gave an explanation of this and corrected a leak) and expensive to respect. Paweł Staszewski reported to me one of his machine got its routing cache disabled after few messages like : [ 2677.850065] Route hash chain too long! [ 2677.850080] Adjust your secret_interval! [82839.662993] Route hash chain too long! [82839.662996] Adjust your secret_interval! [155843.731650] Route hash chain too long! [155843.731664] Adjust your secret_interval! [155843.811881] Route hash chain too long! [155843.811891] Adjust your secret_interval! [155843.858209] vlan0811: 5 rebuilds is over limit, route caching disabled [155843.858212] Route hash chain too long! [155843.858213] Adjust your secret_interval! This is because rt_intern_hash() might be fooled when computing a chain length, because multiple entries with same keys can differ because of TOS (or mark/oif) bits. In the rare case the fast algorithm see a too long chain, and before taking expensive path, we call a helper function in order to not count duplicates of same routes, that only differ with tos/mark/oif bits. This helper works with data already in cpu cache and is not be very expensive, despite its O(N^2) implementation. Paweł Staszewski sucessfully tested this patch on his loaded router.
