|
|
* Arnaldo Carvalho de Melo <acme@conectiva.com.br>
|
|
|
|
|
* - fix leaks on failure at bond_init
|

*
|
|
|
|
|
* 2000/09/30 - Willy Tarreau <willy at meta-x.org>
|
|
|
|
|
* - added trivial code to release a slave device.
|
|
|
|
|
* - fixed security bug (CAP_NET_ADMIN not checked)
|
|
|
|
|
* - implemented MII link monitoring to disable dead links :
|
|
|
|
|
* All MII capable slaves are checked every <miimon> milliseconds
|
|
|
|
|
* (100 ms seems good). This value can be changed by passing it to
|
|
|
|
|
* insmod. A value of zero disables the monitoring (default).
|
|
|
|
|
* - fixed an infinite loop in bond_xmit_roundrobin() when there's no
|
|
|
|
|
* good slave.
|
|
|
|
|
* - made the code hopefully SMP safe
|
|
|
|
|
*
|
|
|
|
|
* 2000/10/03 - Willy Tarreau <willy at meta-x.org>
|
|
|
|
|
* - optimized slave lists based on relevant suggestions from Thomas Davis
|
|
|
|
|
* - implemented active-backup method to obtain HA with two switches:
|
|
|
|
|
* stay as long as possible on the same active interface, while we
|
|
|
|
|
* also monitor the backup one (MII link status) because we want to know
|
|
|
|
|
* if we are able to switch at any time. ( pass "mode=1" to insmod )
|
|
|
|
|
* - lots of stress testings because we need it to be more robust than the
|
|
|
|
|
* wires ! :->
|
|
|
|
|
*
|
|
|
|
|
* 2000/10/09 - Willy Tarreau <willy at meta-x.org>
|
|
|
|
|
* - added up and down delays after link state change.
|
|
|
|
|
* - optimized the slaves chaining so that when we run forward, we never
|
|
|
|
|
* repass through the bond itself, but we can find it by searching
|
|
|
|
|
* backwards. Renders the deletion more difficult, but accelerates the
|
|
|
|
|
* scan.
|
|
|
|
|
* - smarter enslaving and releasing.
|
|
|
|
|
* - finer and more robust SMP locking
|
|
|
|
|
*
|
|
|
|
|
* 2000/10/17 - Willy Tarreau <willy at meta-x.org>
|
|
|
|
|
* - fixed two potential SMP race conditions
|

|
|
|
*
|
|
|
|
|
* 2000/10/18 - Willy Tarreau <willy at meta-x.org>
|
|
|
|
|
* - small fixes to the monitoring FSM in case of zero delays
|
|
|
|
|
* 2000/11/01 - Willy Tarreau <willy at meta-x.org>
|
|
|
|
|
* - fixed first slave not automatically used in trunk mode.
|
|
|
|
|
* 2000/11/10 : spelling of "EtherChannel" corrected.
|
|
|
|
|
* 2000/11/13 : fixed a race condition in case of concurrent accesses to ioctl().
|
|
|
|
|
* 2000/12/16 : fixed improper usage of rtnl_exlock_nowait().

|
*
|
|
|
|
|
* 2001/1/3 - Chad N. Tindel <ctindel at ieee dot org>
|
|
|
|
|
* - The bonding driver now simulates MII status monitoring, just like
|
|
|
|
|
* a normal network device. It will show that the link is down iff
|
|
|
|
|
* every slave in the bond shows that their links are down. If at least
|
|
|
|
|
* one slave is up, the bond's MII status will appear as up.
|
|

|
*
|
|
|
|
|
* 2001/2/7 - Chad N. Tindel <ctindel at ieee dot org>
|
|
|
|
|
* - Applications can now query the bond from user space to get
|
|
|
|
|
* information which may be useful. They do this by calling
|
|
|
|
|
* the BOND_INFO_QUERY ioctl. Once the app knows how many slaves
|
|
|
|
|
* are in the bond, it can call the BOND_SLAVE_INFO_QUERY ioctl to
|
|
|
|
|
* get slave specific information (# link failures, etc). See
|
|
|
|
|
* <linux/if_bonding.h> for more details. The structs of interest
|
|
|
|
|
* are ifbond and ifslave.

|
|
|

|
|
|
|
|
* 2001/5/16 - Jeffrey E. Mast <jeff at mastfamily dot com>
|
|
|
|
|
* - memset did not appropriately initialized the bond rw_locks. Used
|
|
|
|
|
* rwlock_init to initialize to unlocked state to prevent deadlock when
|
|
|
|
|
* first attempting a lock
|
|
|
|
|
* - Called SET_MODULE_OWNER for bond device

|
|
|
|
|
* 2001/5/17 - Tim Anderson <tsa at mvista.com>
|
|
|
|
|
* - 2 paths for releasing for slave release; 1 through ioctl
|
|
|
|
|
* and 2) through close. Both paths need to release the same way.
|
|
|
|
|
* - the free slave in bond release is changing slave status before
|
|
|
|
|
* the free. The netdev_set_master() is intended to change slave state
|
|
|
|
|
* so it should not be done as part of the release process.
|
|
|
|
|
* - Simple rule for slave state at release: only the active in A/B and
|
|
|
|
|
* only one in the trunked case.

|
* - Now call dev_close when releasing a slave so it doesn't screw up
|
|
|
|
|
* out routing table.
|
|
|
|
|
*
|
|
|
|
|
* 2001/6/01 - Chad N. Tindel <ctindel at ieee dot org>
|
|
|
|
|
* - Added /proc support for getting bond and slave information.
|
|
|
|
|
* Information is in /proc/net/<bond device>/info.
|
|
|
|
|
* - Changed the locking when calling bond_close to prevent deadlock.

|
|
|
|
*
|
|
|
|
|
* 2001/8/05 - Janice Girouard <girouard at us.ibm.com>
|
|
|
|
|
* - correct problem where refcnt of slave is not incremented in bond_ioctl
|
|
|
|
|
* so the system hangs when halting.
|
|
|
|
|
* - correct locking problem when unable to malloc in bond_enslave.
|
|
|
|
|
* - adding bond_xmit_xor logic.
|
|
|
|
|
* - adding multiple bond device support.
|
|
|

|
|
|
|

*
|
|
|
|
|
* 2001/9/13 - Takao Indoh <indou dot takao at jp dot fujitsu dot com>
|
|
|
|
|
* - Add the BOND_CHANGE_ACTIVE ioctl implementation
|
|
|
|
|
*
|
|
|
|
|
* 2001/9/14 - Mark Huth <mhuth at mvista dot com>
|
|
|
|
|
* - Change MII_LINK_READY to not check for end of auto-negotiation,
|
|
|
|
|
* but only for an up link.
|
|
|
|
|
*
|
|
|
|
|
* 2001/9/20 - Chad N. Tindel <ctindel at ieee dot org>
|
|
|
|

|
|
|
|
|
* corresponding to a bond wasn't available from the bonding_t
|
|
|
|
|

|
*
|
|
|
|
|
* 2001/11/5 - Mark Huth <mark dot huth at mvista dot com>
|
|
|
|
|
* - Don't take rtnl lock in bond_mii_monitor as it deadlocks under
|
|
|
|
|
* certain hotswap conditions.
|
|
|
|
|
* Note: this same change may be required in bond_arp_monitor ???
|
|
|
|
|
* - Remove possibility of calling bond_sethwaddr with NULL slave_dev ptr
|
|
|
|
|
* - Handle hot swap ethernet interface deregistration events to remove
|
|
|
|
|
* kernel oops following hot swap of enslaved interface
|

|
*
|
|
|
|

|
|
|
|
|
*
|
|
|
|
|
* 2002/02/18 - Erik Habbinga <erik_habbinga at hp dot com>
|
|
|
|
|
* - bond_release(): calling kfree on our_slave after call to
|
|
|
|
|
* bond_restore_slave_flags, not before
|
|
|
|
|
* - bond_enslave(): saving slave flags into original_flags before
|
|
|
|
|
* call to netdev_set_master, so the IFF_SLAVE flag doesn't end
|
|
|
|
|
* up in original_flags
|
|
|
|
|
*
|
|
|
|
|
* 2002/04/05 - Mark Smith <mark.smith at comdev dot cc> and
|
|

|
|
|
|
* to 2.4.18 adding support for multicast.
|
|
|
|
|
*
|
|
|
|
|
* 2002/06/10 - Tony Cureington <tony.cureington * hp_com>
|
|
|
|
|
* - corrected uninitialized pointer (ifr.ifr_data) in bond_check_dev_link;
|
|
|
|
|
* actually changed function to use MIIPHY, then MIIREG, and finally
|
|
|
|
|
* ETHTOOL to determine the link status
|
|
|
|
|
* - fixed bad ifr_data pointer assignments in bond_ioctl
|
|
|
|
|
* - corrected mode 1 being reported as active-backup in bond_get_info;
|
|
|
|
|
* also added text to distinguish type of load balancing (rr or xor)
|
|
|
|
|
* - change arp_ip_target module param from "1-12s" (array of 12 ptrs)
|
|
|
|
|
* to "s" (a single ptr)

|
|
|
* 2002/08/30 - Jay Vosburgh <fubar at us dot ibm dot com>
|
|
|
|
|
* - Removed acquisition of xmit_lock in set_multicast_list; caused
|
|
|
|
|
* deadlock on SMP (lock is held by caller).
|
|
|
|
|
* - Revamped SIOCGMIIPHY, SIOCGMIIREG portion of bond_check_dev_link().
|
|
|
|
|
*
|
|
|
|
|
* 2002/09/18 - Jay Vosburgh <fubar at us dot ibm dot com>
|
|
|
|
|
* - Fixed up bond_check_dev_link() (and callers): removed some magic
|
|
|
|
|
* numbers, banished local MII_ defines, wrapped ioctl calls to
|
|
|
|
|
* prevent EFAULT errors

*
|
|
|
|
|
* 2002/9/30 - Jay Vosburgh <fubar at us dot ibm dot com>

|
|
|
|
|
* hw address.
|
|
|
|
|
*
|
|
|
|
|
* 2002/9/30 - Dan Eisner <eisner at 2robots dot com>
|
|
|
|
|
* - make sure my_ip is set before taking down the link, since
|
|
|
|
|
* not all switches respond if the source ip is not set.

|
|
|
*
|
|
|
|
|
* 2002/10/8 - Janice Girouard <girouard at us dot ibm dot com>
|
|
|
|
|
* - read in the local ip address when enslaving a device
|
|
|
|
|
* - add primary support
|
|
|
|
|
* - make sure 2*arp_interval has passed when a new device
|
|
|
|
|
* is brought on-line before taking it down.

*
|
|
|
|
|
* 2002/09/11 - Philippe De Muyter <phdm at macqel dot be>
|
|
|
|
|
* - Added bond_xmit_broadcast logic.
|
|
|
|
|

|
|
*
|
|
|
|
|
* 2002/10/26 - Laurent Deniel <laurent.deniel at free.fr>
|
|
|
|
|
* - allow to register multicast addresses only on active slave
|
|
|
|
|
* (useful in active-backup mode)
|
|
|
|
|
* - add multicast module parameter
|
|
|
|
|
* - fix deletion of multicast groups after unloading module
|
|
|
|
|
*
|
|
|
|
|
* 2002/11/06 - Kameshwara Rayaprolu <kameshwara.rao * wipro_com>
|
|
|
|
|
* - Changes to prevent panic from closing the device twice; if we close
|
|
|
|
|
* the device in bond_release, we must set the original_flags to down
|
|
|
|
|
* so it won't be closed again by the network layer.

|
|
|
*
|
|
|
|
|
* 2002/11/07 - Tony Cureington <tony.cureington * hp_com>
|
|
|
|
|
* - Fix arp_target_hw_addr memory leak
|
|
|
|
|
* - Created activebackup_arp_monitor function to handle arp monitoring
|
|
|
|
|
* in active backup mode - the bond_arp_monitor had several problems...
|
|
|
|
|
* such as allowing slaves to tx arps sequentially without any delay
|
|
|
|
|
* for a response
|
|
|
|
|
* - Renamed bond_arp_monitor to loadbalance_arp_monitor and re-wrote
|
|
|
|
|
* this function to just handle arp monitoring in load-balancing mode;
|
|
|
|
|
* it is a lot more compact now
|
|
|
|
|
* - Changes to ensure one and only one slave transmits in active-backup
|
|
|
|
|
* mode
|
|
|
|
|
* - Robustesize parameters; warn users about bad combinations of
|
|
|
|
|
* parameters; also if miimon is specified and a network driver does
|
|
|
|
|
* not support MII or ETHTOOL, inform the user of this
|
|
|
|
|
* - Changes to support link_failure_count when in arp monitoring mode
|
|
|
|
|
* - Fix up/down delay reported in /proc
|
|
|
|
|
* - Added version; log version; make version available from "modinfo -d"
|
|
|
|
|
* - Fixed problem in bond_check_dev_link - if the first IOCTL (SIOCGMIIPH)
|
|
|
|
|
* failed, the ETHTOOL ioctl never got a chance
|
|
|
|
|
*
|
|
|
|
|
* 2002/11/16 - Laurent Deniel <laurent.deniel at free.fr>
|
|
|
|
|
* - fix multicast handling in activebackup_arp_monitor
|
|
|
|
|
* - remove one unnecessary and confusing curr_active_slave == slave test
|
|
|
|
|
* in activebackup_arp_monitor
|
|
|
|
|
*
|
|
|
|
|
* 2002/11/17 - Laurent Deniel <laurent.deniel at free.fr>
|
|
|
|
|
* - fix bond_slave_info_query when slave_id = num_slaves
|
|
|
|
|
*
|
|
|
|
|
* 2002/11/19 - Janice Girouard <girouard at us dot ibm dot com>
|
|
|
|
|
* - correct ifr_data reference. Update ifr_data reference
|
|
|
|
|
* to mii_ioctl_data struct values to avoid confusion.
|
|
|
|
|
*
|
|
|
|
|
* 2002/11/22 - Bert Barbe <bert.barbe at oracle dot com>
|

|
|
* - Add support for multiple arp_ip_target
|
|
|
|
|
*
|
|
|
|
|
* 2002/12/13 - Jay Vosburgh <fubar at us dot ibm dot com>
|
|
|
|
|
* - Changed to allow text strings for mode and multicast, e.g.,
|
|
|
|
|
* insmod bonding mode=active-backup. The numbers still work.
|
|
|
|
|
* One change: an invalid choice will cause module load failure,
|
|
|
|
|
* rather than the previous behavior of just picking one.
|
|
|
|
|
* - Minor cleanups; got rid of dup ctype stuff, atoi function
|
|
|
|
|
*
|
|
|
|
|
* 2003/02/07 - Jay Vosburgh <fubar at us dot ibm dot com>
|
|
|
|
|
* - Added use_carrier module parameter that causes miimon to
|
|
|
|
|
* use netif_carrier_ok() test instead of MII/ETHTOOL ioctls.
|
|
|
|
|
* - Minor cleanups; consolidated ioctl calls to one function.

|
|
|
* - Fix bond_mii_monitor() logic error that could result in
|
|
|
|
|
* bonding round-robin mode ignoring links after failover/recovery
|
|
|
|
|
*
|
|
|
|
|
* 2003/03/17 - Jay Vosburgh <fubar at us dot ibm dot com>
|
|
|
|
|
* - kmalloc fix (GFP_KERNEL to GFP_ATOMIC) reported by
|
|
|
|
|
* Shmulik dot Hen at intel.com.
|
|
|
|
|
* - Based on discussion on mailing list, changed use of
|
|
|
|
|
* update_slave_cnt(), created wrapper functions for adding/removing
|
|
|
|
|
* slaves, changed bond_xmit_xor() to check slave_cnt instead of
|
|
|
|
|
* checking slave and slave->dev (which only worked by accident).
|
|
|
|
|
* - Misc code cleanup: get arp_send() prototype from header file,
|
|
|
|
|
* add max_bonds to bonding.txt.

|
|
|
|
|
* Shmulik Hen <shmulik.hen at intel dot com>
|
|
|
|
|
* - Make sure only bond_attach_slave() and bond_detach_slave() can
|
|
|
|
|
* manipulate the slave list, including slave_cnt, even when in
|
|
|
|
|
* bond_release_all().
|
|
|
|
|
* - Fixed hang in bond_release() with traffic running:

|
|
|
|
|
* Shmulik Hen <shmulik.hen at intel dot com>
|
|
|
|
|

|
|
|
|
|
* netdev_set_master() must not be called from within the bond lock.

*
|
|
|
|
|
* 2003/03/18 - Amir Noam <amir.noam at intel dot com>
|
|
|
|
|
* - Added support for getting slave's speed and duplex via ethtool.
|
|
|
|
|
* Needed for 802.3ad and other future modes.

|
|
|
* Shmulik Hen <shmulik.hen at intel dot com>
|
|
|
|
|
* - Enable support of modes that need to use the unique mac address of
|
|
|
|
|
* each slave.
|
|
|
|
|
* * bond_enslave(): Moved setting the slave's mac address, and
|
|
|
|
|
* openning it, from the application to the driver. This breaks
|
|
|
|
|
* backward comaptibility with old versions of ifenslave that open
|
|
|
|
|
* the slave before enalsving it !!!.
|
|
|
|
|
* * bond_release(): The driver also takes care of closing the slave
|
|
|
|
|
* and restoring its original mac address.
|
|
|
|
|
* - Removed the code that restores all base driver's flags.
|
|
|
|
|
* Flags are automatically restored once all undo stages are done
|
|
|
|
|
* properly.
|
|
|
|
|
* - Block possibility of enslaving before the master is up. This
|
|
|
|
|
* prevents putting the system in an unstable state.

|
|
|
|
|
* 2003/05/01 - Amir Noam <amir.noam at intel dot com>
|

|
|
|
|
|
* 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com>
|
|
|
|
|
* - Fixed bug in bond_release_all(): save old value of curr_active_slave
|
|
|
|
|
* before setting it to NULL.
|
|
|
|
|
* - Changed driver versioning scheme to include version number instead
|
|
|
|
|
* of release date (that is already in another field). There are 3
|
|
|
|
|
* fields X.Y.Z where:
|
|
|
|
|
* X - Major version - big behavior changes
|
|
|
|
|
* Y - Minor version - addition of features
|
|
|
|
|
* Z - Extra version - minor changes and bug fixes
|
|
|
|
|
* The current version is 1.0.0 as a base line.

* 2003/05/01 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
|
|
|
|
|
* Amir Noam <amir.noam at intel dot com>
|
|
|
|
|
* - Added support for lacp_rate module param.
|
|
|
|
|
* - Code beautification and style changes (mainly in comments).
|
|
|
|
|
* new version - 1.0.1
|
|
|
|
|
*
|
|
|
|
|
* 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com>
|
|
|
|
|
* - Based on discussion on mailing list, changed locking scheme
|
|
|
|
|
* to use lock/unlock or lock_bh/unlock_bh appropriately instead
|
|
|
|
|
* of lock_irqsave/unlock_irqrestore. The new scheme helps exposing
|
|
|
|
|
* hidden bugs and solves system hangs that occurred due to the fact
|
|
|
|
|
* that holding lock_irqsave doesn't prevent softirqs from running.
|
|
|
|
|
* This also increases total throughput since interrupts are not
|
|
|
|
|
* blocked on each transmitted packets or monitor timeout.
|
|
|
|
|
* new version - 2.0.0
|
|
|

|
|
|
|
|
* 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com>
|
|
|
|
|
* - Added support for Transmit load balancing mode.
|
|
|
|
|
* - Concentrate all assignments of curr_active_slave to a single point
|
|
|
|
|
* so specific modes can take actions when the primary adapter is
|
|
|
|
|
* changed.
|
|
|
|
|
* - Take the updelay parameter into consideration during bond_enslave
|
|
|
|
|
* since some adapters loose their link during setting the device.
|
|
|
|
|
* - Renamed bond_3ad_link_status_changed() to
|
|
|
|
|
* bond_3ad_handle_link_change() for compatibility with TLB.
|
|
|
|
|

|
|
|
|
|
* - Fix ifenslave -c causing bond to loose existing routes;
|
|
|
|
|
* added bond_set_mac_address() that doesn't require the
|
|
|
|
|
* bond to be down.
|
|
|
|
|
* - In conjunction with fix for ifenslave -c, in
|
|
|
|
|
* bond_change_active(), changing to the already active slave
|
|
|
|
|
* is no longer an error (it successfully does nothing).

*
|
|
|
|
|
* 2003/08/06 - Amir Noam <amir.noam at intel dot com>
|
|
|
|
|
* - Back port from 2.6: use alloc_netdev(); fix /proc handling;
|
|
|
|
|
* made stats a part of bond struct so no need to allocate
|
|
|
|
|
* and free it separately; use standard list operations instead
