* [NET]: Implement network device movement between namespacesEric W. Biederman2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces NETIF_F_NETNS_LOCAL a flag to indicate a network device is local to a single network namespace and should never be moved. Useful for pseudo devices that we need an instance in each network namespace (like the loopback device) and for any device we find that cannot handle multiple network namespaces so we may trap them in the initial network namespace. This patch introduces the function dev_change_net_namespace a function used to move a network device from one network namespace to another. To the network device nothing special appears to happen, to the components of the network stack it appears as if the network device was unregistered in the network namespace it is in, and a new device was registered in the network namespace the device was moved to. This patch sets up a namespace device destructor that upon the exit of a network namespace moves all of the movable network devices to the initial network namespace so they are not lost.

* [NET]: Make the device list and device lookups per namespace.Eric W. Biederman2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch makes most of the generic device layer network namespace safe. This patch makes dev_base_head a network namespace variable, and then it picks up a few associated variables. The functions: dev_getbyhwaddr dev_getfirsthwbytype dev_get_by_flags dev_get_by_name __dev_get_by_name dev_get_by_index __dev_get_by_index dev_ioctl dev_ethtool dev_load wireless_process_ioctl were modified to take a network namespace argument, and deal with it. vlan_ioctl_set and brioctl_set were modified so their hooks will receive a network namespace argument. So basically anthing in the core of the network stack that was affected to by the change of dev_base was modified to handle multiple network namespaces. The rest of the network stack was simply modified to explicitly use &init_net the initial network namespace. This can be fixed when those components of the network stack are modified to handle multiple network namespaces. For now the ifindex generator is left global. Fundametally ifindex numbers are per namespace, or else we will have corner case problems with migration when we get that far. At the same time there are assumptions in the network stack that the ifindex of a network device won't change. Making the ifindex number global seems a good compromise until the network stack can cope with ifindex changes when you change namespaces, and the like. Signed-off-by: Eric W.

* [NET]: Support multiple network namespaces with netlinkEric W. Biederman2007-10-10
| | | | | | | | | | | | | | | | | | | | | Each netlink socket will live in exactly one network namespace, this includes the controlling kernel sockets. This patch updates all of the existing netlink protocols to only support the initial network namespace. Request by clients in other namespaces will get -ECONREFUSED. As they would if the kernel did not have the support for that netlink protocol compiled in. As each netlink protocol is updated to be multiple network namespace safe it can register multiple kernel sockets to acquire a presence in the rest of the network namespaces. The implementation in af_netlink is a simple filter implementation at hash table insertion and hash table look up time. Signed-off-by: Eric W.

* [NET]: Make device event notification network namespace safeEric W. Biederman2007-10-10
| | | | | | | | | | | | | | | | | | Every user of the network device notifiers is either a protocol stack or a pseudo device. If a protocol stack that does not have support for multiple network namespaces receives an event for a device that is not in the initial network namespace it quite possibly can get confused and do the wrong thing. To avoid problems until all of the protocol stacks are converted this patch modifies all netdev event handlers to ignore events on devices that are not in the initial network namespace. As the rest of the code is made network namespace aware these checks can be removed. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* [NET]: Make packet reception network namespace safeEric W. Biederman2007-10-10

* [NET]: Make socket creation namespace safe.Eric W. Biederman2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | This patch passes in the namespace a new socket should be created in and has the socket code do the appropriate reference counting. By virtue of this all socket create methods are touched. In addition the socket create methods are modified so that they will fail if you attempt to create a socket in a non-default network namespace. Failing if we attempt to create a socket outside of the default network namespace ensures that as we incrementally make the network stack network namespace aware we will not export functionality that someone has not audited and made certain is network namespace safe. Allowing us to partially enable network namespaces before all of the exotic protocols are supported. Any protocol layers I have missed will fail to compile because I now pass an extra parameter into the socket creation code.

* [NET]: Make /proc/net per network namespaceEric W. Biederman2007-10-10
| | | | | | | | | | | | | | | | | | This patch makes /proc/net per network namespace. It modifies the global variables proc_net and proc_net_stat to be per network namespace. The proc_net file helpers are modified to take a network namespace argument, and all of their callers are fixed to pass &init_net for that argument. This ensures that all of the /proc/net files are only visible and usable in the initial network namespace until the code behind them has been updated to be handle multiple network namespaces. Making /proc/net per namespace is necessary as at least some files in /proc/net depend upon the set of network devices which is per network namespace, and even more files in /proc/net have contents that are relevant to a single network namespace.

| | | | | | | | | | | | | | | | | | | | This dongle does not follow the usb-irda specification, so it needs its own special driver. First, it uses control URBs for data transfer, instead of bulk or interrupt transfers; the only interrupt endpoint exposed seems to be a dummy to prevent the interface from being rejected. Second, it uses obfuscation and padding at the USB traffic level, for no apparent reason other than to make reverse engineering harder (full details on obfuscation in comments at beginning of source). Although it is advertised as a "4 Mbps FIR dongle", it apparently loses packets at speeds greater than 57600 bps. On plugin, this dongle reports vendor and device IDs: 0x07d0:0x4959 .

* [NET] netconsole: Support dynamic reconfiguration using configfsSatyam Sharma2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based upon initial work by Keiichi Kii <k-keiichi@bx.jp.nec.com>. This patch introduces support for dynamic reconfiguration (adding, removing and/or modifying parameters of netconsole targets at runtime) using a userspace interface exported via configfs. Documentation is also updated accordingly. Issues and brief design overview: (1) Kernel-initiated creation / destruction of kernel objects is not possible with configfs -- the lifetimes of the "config items" is managed exclusively from userspace. But netconsole must support boot/module params too, and these are parsed in kernel and hence netpolls must be setup from the kernel. Joel Becker suggested to separately manage the lifetimes of the two kinds of netconsole_target objects -- those created via configfs mkdir(2) from userspace and those specified from the boot/module option string. This adds complexity and some redundancy here and also means that boot/module param-created targets are not exposed through the configfs namespace (and hence cannot be updated / destroyed dynamically). However, this saves us from locking / refcounting complexities that would need to be introduced in configfs to support kernel-initiated item creation / destroy there. (2) In configfs, item creation takes place in the call chain of the mkdir(2) syscall in the driver subsystem. If we used an ioctl(2) to create / destroy objects from userspace, the special userspace program is able to fill out the structure to be passed into the ioctl and hence specify attributes such as local interface that are required at the time we set up the netpoll. For configfs, this information is not available at the time of mkdir(2). So, we keep all newly-created targets (via configfs) disabled by default. The user is expected to set various attributes appropriately (including the local network interface if required) and then write(2) "1" to the "enabled" attribute. Thus, netpoll_setup() is then called on the set parameters in the context of _this_ write(2) on the "enabled" attribute itself. This design enables the user to reconfigure existing netconsole targets at runtime to be attached to newly-come-up interfaces that may not have existed when netconsole was loaded or when the targets were actually created. All this effectively enables us to get rid of custom ioctls. (3) Ultra-paranoid configfs attribute show() and store() operations, with sanity and input range checking, using only safe string primitives, and compliant with the recommendations in Documentation/filesystems/sysfs.txt. (4) A new function netpoll_print_options() is created in the netpoll API, that just prints out the configured parameters for a netpoll structure. netpoll_parse_options() is modified to use that and it is also exported to be used from netconsole.

* [NET] netconsole: Support multiple logging targetsSatyam Sharma2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Based upon initial work by Keiichi Kii <k-keiichi@bx.jp.nec.com>. This patch introduces support for multiple targets, independent of CONFIG_NETCONSOLE_DYNAMIC -- this is useful even in the default case and (including the infrastructure introduced in previous patches) doesn't really add too many bytes to module text. All the complexity (and size) comes with the dynamic reconfigurability / userspace interface patch, and so it's plausible users may want to keep this enabled but that disabled (say to avoid a dependency on CONFIG_CONFIGFS_FS too). Also update documentation to mention the use of ";" separator to specify multiple logging targets in the boot/module option string. Brief overview: We maintain a target_list (and corresponding lock). Get rid of the static "default_target" and introduce allocation and release functions for our netconsole_target objects (but keeping sure to preserve previous behaviour such as default values). During init_netconsole(), ";" is used as the separator to identify multiple target specifications in the boot/module option string. The target specifications are parsed and netpolls setup. During exit, the target_list is torn down and all items released.

* [NET] netconsole: Introduce netconsole_netdev_notifierSatyam Sharma2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | Based upon initial work by Keiichi Kii <k-keiichi@bx.jp.nec.com>. To update fields of underlying netpoll structure at runtime on corresponding NETDEV_CHANGEADDR or NETDEV_CHANGENAME notifications. ioctl(SIOCSIFHWADDR or SIOCSIFNAME) could be used to change the hardware/MAC address or name of the local interface that our netpoll is attached to. Whenever this happens, netdev notifier chain is called out with the NETDEV_CHANGEADDR or NETDEV_CHANGENAME event message. We respond to that and update the local_mac or dev_name field of the struct netpoll. This makes sense anyway, but is especially required for dynamic netconsole because the netpoll structure's internal members become user visible files when either sysfs or configfs are used. So this helps us to keep up with the MAC address/name changes and keep values in struct netpoll uptodate. [ Note that ioctl(SIOCSIFADDR) to change IP address of interface at runtime is not handled (to update local_ip of netpoll) on purpose -- some setups may set the local_ip to a private address, not necessary the actual IP address of the sender host, as presently allowed. ] Signed-off-by: Satyam Sharma <satyam@infradead.org> Signed-off-by: Keiichi Kii <k-keiichi@bx.jp.nec.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: David S.

* [NET] netconsole: Simplify boot/module option setup logicSatyam Sharma2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Based upon initial work by Keiichi Kii <k-keiichi@bx.jp.nec.com>. Presently, boot/module parameters are set up quite differently for the case of built-in netconsole (__setup() -> obsolete_checksetup() -> netpoll_parse_options() -> strlen(config) == 0 in init_netconsole()) vs modular netconsole (module_param_string() -> string copied to the config variable -> strlen(config) != 0 init_netconsole() -> netpoll_parse_options()). This patch makes both of them similar by doing exactly the equivalent of a module_param_string() in option_setup() also -- just copying the param string passed from the kernel command line into "config" variable. So, strlen(config) != 0 in both cases, and netpoll_parse_options() is always called from init_netconsole(), thus making the setup logic for both cases similar. Now, option_setup() is only ever called / used for the built-in case, so we put it inside a #ifndef MODULE, otherwise gcc will complain about option_setup() being "defined but not used". Also, the "configured" variable is redundant with this patch and hence removed.

The (!np.dev) check in write_msg() is bogus (always false), because: np.dev is set by netpoll_setup(), which is called by init_netconsole() before register_console(), so write_msg() cannot be triggered unless netpoll_setup() successfully set np.dev. Also np.dev cannot go away from under us, because netpoll_setup() grabs us reference on it. So let's remove the bogus check.

* [NET]: Make NAPI polling independent of struct net_device objects.Stephen Hemminger2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several devices have multiple independant RX queues per net device, and some have a single interrupt doorbell for several queues. In either case, it's easier to support layouts like that if the structure representing the poll is independant from the net device itself. The signature of the ->poll() call back goes from: int foo_poll(struct net_device *dev, int *budget) to int foo_poll(struct napi_struct *napi, int budget) The caller is returned the number of RX packets processed (or the number of "NAPI credits" consumed if you want to get abstract). The callee no longer messes around bumping dev->quota, *budget, etc. because that is all handled in the caller upon return. The napi_struct is to be embedded in the device driver private data structures. Furthermore, it is the driver's responsibility to disable all NAPI instances in it's ->stop() device close handler. Since the napi_struct is privatized into the driver's private data structures, only the driver knows how to get at all of the napi_struct instances it may have per-device. With lots of help and suggestions from Rusty Russell, Roland Dreier, Michael Chan, Jeff Garzik, and Jamal Hadi Salim. Bug fixes from Thomas Graf, Roland Dreier, Peter Zijlstra, Joseph Fannin, Scott Wood, Hans J. Koch, and Michael Chan. [ Ported to current tree and all drivers converted.

* [MAC80211]: improved short preamble handlingDaniel Drake2007-10-10
| | | | | | | | | | | | | | | | | | | | | | | Similarly to CTS protection, whether short preambles are used for 802.11b transmissions should be a per-subif setting, not device global. For STAs, this patch makes short preamble handling automatic based on the ERP IE. For APs, hostapd still uses the prism ioctls, but the write ioctl has been restricted to AP-only subifs. ieee80211_txrx_data.short_preamble (an unused field) was removed. Unfortunately, some API changes were required for the following functions: - ieee80211_generic_frame_duration - ieee80211_rts_duration - ieee80211_ctstoself_duration - ieee80211_rts_get - ieee80211_ctstoself_get Affected drivers were updated accordingly.

* sata_mv: correct S/G table limitsJeff Garzik2007-10-09
| | | | | | | | | | | | The recent mv_fill_sg() rewrite, to fix a data corruption problem related to IOMMU virtual merging, forgot to account for the potentially-increased size of the scatter/gather table after its run. Additionally, the DMA boundary is reduced from 0xffffffff to 0xffff to more closely match the needs of mv_fill_sg().

* Correct Makefile rule for generating custom keymapMaarten Bressers2007-10-08
| | | | | | | | | | | | | | | | | | | | | | When building a custom keymap, after setting GENERATE_KEYMAP := 1 in drivers/char/Makefile, the kernel build fails like this: CC drivers/char/vt.o make[2]: *** No rule to make target `drivers/char/%.map', needed by `drivers/char/defkeymap.c'. Stop. make[1]: *** [drivers/char] Error 2 make: *** [drivers] Error 2 This was caused by commit af8b128719f5248e542036ea994610a29d0642a6, which deleted a necessary colon from the Makefile rule that generates the keymap, since that rule contains both a target and a target-pattern.

* | VT_WAITACTIVE: Avoid returning EINTR when not necessaryLinus Torvalds2007-10-07
|/ | | | | | | | | | | | | | | | | | | We should generally prefer to return ERESTARTNOHAND rather than EINTR, so that processes with unhandled signals that get ignored don't return EINTR. This can help with X startup issues: Fatal server error: xf86OpenConsole: VT_WAITACTIVE failed: Interrupted system call although the real fix is having the X server always retry EINTR regardless (since EINTR does happen for signals that have handlers installed). Keithp has a patch for that. Regardless, ERESTARTNOHAND is the correct thing to use. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* Fix non-terminated PCI match table in PowerMac IDEBenjamin Herrenschmidt2007-10-06
| | | | | | | | | | | | | | | | | | The PCI device table in the powermac IDE driver isn't properly terminated. Depending on how your kernel is linked and other random factors, you can end up with this driver matched against any other PCI device in your system, possibly crashing at boot. Thanks to Heikki for tracking this down with me, the bug have been there for some time, though it rarely hurts due to luck. In this case, the switch from .22 to .23-rc9 is causing it to show up due to differences in the resulting layout of .data I suppose.
