2008-03-14SUNRPC: Add a generic RPC credentialTrond Myklebust
Add an rpc credential that is not tied to any particular auth mechanism, but that can be cached by NFS, and later used to look up a cred for whichever auth mechanism that turns out to be valid when the RPC call is being made. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2008-03-14SUNRPC: Fix RPCAUTH_LOOKUP_ROOTCREDSTrond Myklebust
The current RPCAUTH_LOOKUP_ROOTCREDS flag only works for AUTH_SYS authentication, and then only as a special case in the code. This patch removes the auth_sys special casing, and replaces it with generic code. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>

2008-03-04[IPCONFIG]: The kernel gets no IP from some DHCP serversStephen Hemminger
From: Stephen Hemminger <shemminger@linux-foundation.org> Based upon a patch by Marcel Wappler: This patch fixes a DHCP issue of the kernel: some DHCP servers (i.e. in the Linksys WRT54Gv5) are very strict about the contents of the DHCPDISCOVER packet they receive from clients. Table 5 in RFC2131 page 36 requests the fields 'ciaddr' and 'siaddr' MUST be set to '0'. These DHCP servers ignore Linux kernel's DHCP discovery packets with these two fields set to '255.255.255.255' (in contrast to popular DHCP clients, such as 'dhclient' or 'udhcpc'). This leads to a not booting system. Signed-off-by: David S. Miller <davem@davemloft.net>

2008-03-04rc80211-pid: fix rate adjustmentStefano Brivio
Merge rate_control_pid_shift_adjust() to rate_control_pid_adjust_rate() in order to make the learning algorithm aware of constraints on rates. Also add some comments and rename variables. This fixes a bug which prevented 802.11b/g non-AP STAs from working with 802.11b only AP STAs. This patch was originally destined for 2.6.26, and is being backported to fix a user reported problem in post-2.6.24 kernels.

2008-03-04[NETPOLL]: Revert two bogus cleanups that broke netconsole.David S. Miller
Based upon a report by Andrew Morton and code analysis done by Jarek Poplawski. This reverts 33f807ba0d9259e7c75c7a2ce8bd2787e5b540c7 ("[NETPOLL]: Kill NETPOLL_RX_DROP, set but never tested.") and c7b6ea24b43afb5749cb704e143df19d70e23dea ("[NETPOLL]: Don't need rx_flags."). The rx_flags did get tested for zero vs. non-zero and therefore we do need those tests and that code which sets NETPOLL_RX_DROP et al. Signed-off-by: David S. Miller <davem@davemloft.net>

Since a5fbb6d1064be885d2a6b82f625186753cf74848 "KVM: fix !SMP build error" smp_call_function isn't a define anymore that folds into nothing but a define that calls up_smp_call_function with all parameters. Hence we cannot #ifdef out the unused code anymore... This seems to be the preferred method, so do this for s390 as well. net/iucv/iucv.c: In function 'iucv_cleanup_queue': net/iucv/iucv.c:657: error: '__iucv_cleanup_queue' undeclared Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Josef 'Jeff' Sipek <jeffpc@josefsipek.net> Signed-off-by: Ursula Braun <braunu@de.ibm.com> Signed-off-by: David S.

It makes fackets_out to grow too slowly compared with the real write queue. This shouldn't cause those BUG_TRAP(packets <= tp->packets_out) to trigger but how knows how such inconsistent fackets_out affects here and there around TCP when everything is nowadays assuming accurate fackets_out.

2008-02-28[SCTP]: Clean up naming conventions of sctp protocol/address family registrationNeil Horman
I noticed while looking into some odd behavior in sctp, that the variable name sctp_pf_inet6_specific was used twice to represent two different pieces of data (its both a structure name and a pointer to that type of structure), which is confusing to say the least, and potentially dangerous depending on the variable scope. This patch cleans that up, and makes the protocol and address family registration names in SCTP more regular, increasing readability.

2008-02-28[IPCOMP]: Disable BH on output when using shared tfmHerbert Xu
Because we use shared tfm objects in order to conserve memory, (each tfm requires 128K of vmalloc memory), BH needs to be turned off on output as that can occur in process context. Previously this was done implicitly by the xfrm output code. That was lost when it became lockless. So we need to add the BH disabling to IPComp directly.
