2011-04-04IPVS: fix NULL ptr dereference in ip_vs_ctl.c ip_vs_genl_dump_daemons()Hans Schillstrom
ipvsadm -ln --daemon will trigger a Null pointer exception because ip_vs_genl_dump_daemons() uses skb_net() instead of skb_sknet(). To prevent others from NULL ptr a check is made in ip_vs.h skb_net().

2011-04-04netfilter: h323: bug in parsing of ASN1 SEQOF fieldDavid Sterba
Static analyzer of clang found a dead store which appears to be a bug in reading count of items in SEQOF field, only the lower byte of word is stored. This may lead to corrupted read and communication shutdown. The bug has been in the module since it's first inclusion into linux kernel. [Patrick: the bug is real, but without practical consequence since the largest amount of sequence-of members we parse is 30.] Signed-off-by: David Sterba <dsterba@suse.cz> Signed-off-by: Patrick McHardy <kaber@trash.net>
2011-04-04netfilter: ipset: references are protected by rwlock instead of mutexJozsef Kadlecsik
The timeout variant of the list:set type must reference the member sets. However, its garbage collector runs at timer interrupt so the mutex protection of the references is a no go. Therefore the reference protection is converted to rwlock. Signed-off-by: Jozsef Kadlecsik <kadlec@blackhole.kfki.hu> Signed-off-by: Patrick McHardy <kaber@trash.net>

2011-04-02net: convert SMSC USB net drivers to hw_featuresMichał Mirosław
There's a race (not fixed here) in smsc75xx in setting RFE_CTL that's not properly handled via rfe_ctl_lock. Spinlock is not a good tool here, as this has to wait for URB completion (or maybe just submission) after issuing register write request. Otherwise, the rfe_ctl might be changed just after spin_unlock() and device left programmed with other value. smsc95xx has increased hard_header_len for the case of TX checksumming. smsc75xx is fixed to advertise IP+IPV6_CSUM instead of HW_CSUM as it does not use csum_start/csum_offset.

2011-04-02usbnet: use eth%d name for known ethernet devicesArnd Bergmann
The documentation for the USB ethernet devices suggests that only some devices are supposed to use usb0 as the network interface name instead of eth0. The logic used there, and documented in Kconfig for CDC is that eth0 will be used when the mac address is a globally assigned one, but usb0 is used for the locally managed range that is typically used on point-to-point links. Unfortunately, this has caused a lot of pain on the smsc95xx device that is used on the popular pandaboard without an EEPROM to store the MAC address, which causes the driver to call random_ether_address(). Obviously, there should be a proper MAC addressed assigned to the device, and discussions are ongoing about how to solve this, but this patch at least makes sure that the default interface naming gets a little saner and matches what the user can expect based on the documentation, including for new devices. The approach taken here is to flag whether a device might be a point-to-point link with the new FLAG_POINTTOPOINT setting in the usbnet driver_info. A driver can set both FLAG_POINTTOPOINT and FLAG_ETHER if it is not sure (e.g. cdc_ether), or just one of the two. The usbnet framework only looks at the MAC address for device naming if both flags are set, otherwise it trusts the flag.

2011-03-31drivers/net: Remove IRQF_SAMPLE_RANDOM flag from network driversJavier Martinez Canillas
The IRQF_SAMPLE_RANDOM flag is marked as deprecated and will be removed. Every input point to the kernel's entropy pool have to better document the type of entropy source it is. drivers/char/random.c now implements a set of interfaces that can be used for devices to collect enviromental noise. IRQF_SAMPLE_RANDOM will be replaced with these add_*_randomness exported functions. Network drivers are not a good source of entropy. They use as a source of entropy essentially a remote host. Which means that the source of entropy can be potentially controlled by an attacker. Also, with heavy workloads the entropy decreases due to less hardware interrupts happening thanks to irq mitigation and NAPI. If a system relies in its network interface as a entropy source it has a false sense of security. Systems that don't have devices whose drivers are good sources of entropy, should either use a hardware random number generator or feed the kernel's entropy pool from userspace using other sources of entropy such as EGD, video_entropyd, timer_entropyd and audio-entropyd.

2011-03-31enic: Add support for PORT_REQUEST_PREASSOCIATE_RRRoopa Prabhu
Current enic code only supports ASSOCIATE and DISASSOCIATE port profile operations. This patch adds enic support for port profile PORT_REQUEST_PREASSOCIATE_RR operation. The VIC adapter (8021qbh) is capable of handling port profile requests done in two steps namely PREASSOCIATE_RR and ASSOCIATE today. The motivation to support PREASSOCIATE_RR comes mainly from its use as an optimization during VM migration ie, to do resource reservation on destination host before resources on source host are released. PREASSOCIATE_RR is a VDP operation and according to the latest at IEEE, 8021qbh will also need to support VDP commands. In addition to handling the new PORT_REQUEST_PREASSOCIATE_RR operation this patch also does the below: - Introduces handlers for PORT_REQUEST operations - Moves most of the port profile handling code to new files enic_pp.[ch] - Uses new fw devcmds for port profile operations Signed-off-by: Roopa Prabhu <roprabhu@cisco.com> Signed-off-by: David Wang <dwang2@cisco.com> Signed-off-by: Christian Benvenuti <benve@cisco.com> Signed-off-by: David S.
