If the call to xprt_transmit() fails due to socket buffer space exhaustion, we do not need to re-encode the RPC message when we loop back through call_transmit. Re-encoding can actually end up triggering the WARN_ON() in call_decode() if we re-encode something like a read() request and auth->au_rslack has changed. It can also cause us to increment the RPCSEC_GSS sequence number beyond the limits of the allowed window.

The generic netlink family builds on top of netlink and provides simplifies access for the less demanding netlink users. It solves the problem of protocol numbers running out by introducing a so called controller taking care of id management and name resolving. Generic netlink modules register themself after filling out their id card (struct genl_family), after successful registration the modules are able to register callbacks to command numbers by filling out a struct genl_ops and calling genl_register_op(). The registered callbacks are invoked with attributes parsed making life of simple modules a lot easier. Although generic netlink modules can request static identifiers, it is recommended to use GENL_ID_GENERATE and to let the controller assign a unique identifier to the module. Userspace applications will then ask the controller and lookup the idenfier by the module name. Due to the current multicast implementation of netlink, the number of generic netlink modules is restricted to 1024 to avoid wasting memory for the per socket multiacst subscription bitmask.

Introduces netlink_run_queue() to handle the receive queue of a netlink socket in a generic way. Processes as much as there was in the queue upon entry and invokes a callback function for each netlink message found. The callback function may refuse a message by returning a negative error code but setting the error pointer to 0 in which case netlink_run_queue() will return with a qlen != 0.

Thomas Graf authored
Introduces a new type-safe interface for netlink message and attributes handling. The interface is fully binary compatible with the old interface towards userspace. Besides type safety, this interface features attribute validation capabilities, simplified message contstruction, and documentation. The resulting netlink code should be smaller, less error prone and easier to understand. Signed-off-by: Thomas Graf <tgraf@suug.ch> Signed-off-by: David S. Miller <davem@davemloft.net>

The existing connection tracking subsystem in netfilter can only handle ipv4. There were basically two choices present to add connection tracking support for ipv6. We could either duplicate all of the ipv4 connection tracking code into an ipv6 counterpart, or (the choice taken by these patches) we could design a generic layer that could handle both ipv4 and ipv6 and thus requiring only one sub-protocol (TCP, UDP, etc.) connection tracking helper module to be written. In fact nf_conntrack is capable of working with any layer 3 protocol. The existing ipv4 specific conntrack code could also not deal with the pecularities of doing connection tracking on ipv6, which is also cured here. For example, these issues include: 1) ICMPv6 handling, which is used for neighbour discovery in ipv6 thus some messages such as these should not participate in connection tracking since effectively they are like ARP messages 2) fragmentation must be handled differently in ipv6, because the simplistic "defrag, connection track and NAT, refrag" (which the existing ipv4 connection tracking does) approach simply isn't feasible in ipv6 3) ipv6 extension header parsing must occur at the correct spots before and after connection tracking decisions, and there were no provisions for this in the existing connection tracking design 4) ipv6 has no need for stateful NAT The ipv4 specific conntrack layer is kept around, until all of the ipv4 specific conntrack helpers are ported over to nf_conntrack and it is feature complete. Once that occurs, the old conntrack stuff will get placed into the feature-removal-schedule and we will fully kill it off 6 months later.

recalc_task_prio() is called from activate_task() to calculate dynamic priority and interactive credit for the activating task. For real-time scheduling process, all that dynamic calculation is thrown away at the end because rt priority is fixed. Patch to optimize recalc_task_prio() away for rt processes.

The problem (eject not working on ATAPI LS-120 drive) is caused by idefloppy_ioctl() function which *first* tries generic_ide_ioctl() and *only* if it fails with -EINVAL, proceeds with the specific ioctls. The generic eject command fails with something other than -EINVAL and the specific one is never executed. This patch fixes it by first going through the internal ioctls and only trying generic_ide_ioctl() if none of them matches.

The siimage driver proports to support the Adaptec SA-1210 SATA controller. However, at least some of those cards boot-up with their interrupts disabled internally. The siimage driver currently ignores that fact, so that driver does not actually work with those cards. This patch enables those interrupts on cards that need it.

AGP shouldn't use "global_flush_tlb()" to flush the AGP mappings, that i spurely an x86'ism. The proper AGP mapping flusher that should be used is "flush_agp_mappings()", which on x86 obviously happens to do a global TLB flush. This makes AGP (or at least the config _I_ happen to use) compile again on ppc64. Signed-off-by: Linus Torvalds <torvalds@osdl.org>

This patch started life as a response to fedora specific ide subsystem changes that made error handling of my ATAPI tape drive fail; the specifics are in https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=160868 The insertion of the statement rq->errors = err; near the end of ide_end_drive_cmd() in drivers/ide/ide-io.c means that rq->errors does not contain what it needs to in idescsi_end_request() in drivers/scsi/ide-scsi.c anymore. Recent mainline kernels now also have this change. The patch below makes ide-scsi whole. Signed-off-by: Willem Riede <wrlk@riede.org> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

Devices driven by ide-cs will appear under /sys/devices instead of the appropriate PCMCIA device.

Without this patch, any user can cause nfnetlink subsystems to be autoloaded.

The reply tuple of the PNS->PAC expectation was using the wrong call id. So we had the following situation: - PNS behind NAT firewall - PNS call id requires NATing - PNS->PAC gre packet arrives first then the PNS->PAC expectation is matched, and the other expectation is deleted, but the PAC->PNS gre packets do not match the gre conntrack because the call id is wrong. We also cannot use ip_nat_follow_master(). Signed-off-by: Philip Craig <philipc@snapgear.com> Signed-off-by: Harald Welte <laforge@netfilter.org> Signed-off-by: David S. Miller <davem@davemloft.net>
