Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

Debatable -- the current comment is located at the callsite of ops->get_sset_count(), which is where an implementor might think to add a new call.

#include <linux/vmalloc.h>
include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

ethtool: Change ETHTOOL_PHYS_ID implementation to allow dropping RTNL The ethtool ETHTOOL_PHYS_ID command runs for an arbitrarily long period of time, holding the RTNL lock. This blocks routing updates, device enumeration, and various important operations that one might want to keep running while hunting for the flashing LED. We need to drop the RTNL lock during this operation, but currently the core implementation is a thin wrapper around a driver operation and drivers may well depend upon holding the lock. Define a new driver operation 'set_phys_id' with an argument that sets the ID indicator on/off/inactive/active (the last optional, for any driver or firmware that prefers to handle blinking asynchronously). When this is defined, the ethtool core drops the lock while waiting and only acquires it around calls to this operation. Deprecate the 'phys_id' operation in favour of this. It can be removed once all in-tree drivers are converted. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

[IPv4/IPv6]: UFO Scatter-gather approach Attached is kernel patch for UDP Fragmentation Offload (UFO) feature. 1. This patch incorporate the review comments by Jeff Garzik. 2. Renamed USO as UFO (UDP Fragmentation Offload) 3. udp sendfile support with UFO This patches uses scatter-gather feature of skb to generate large UDP datagram. Below is a "how-to" on changes required in network device driver to use the UFO interface. UDP Fragmentation Offload (UFO) Interface: ------------------------------------------- UFO is a feature wherein the Linux kernel network stack will offload the IP fragmentation functionality of large UDP datagram to hardware. This will reduce the overhead of stack in fragmenting the large UDP datagram to MTU sized packets 1) Drivers indicate their capability of UFO using dev->features |= NETIF_F_UFO | NETIF_F_HW_CSUM | NETIF_F_SG NETIF_F_HW_CSUM is required for UFO over ipv6. 2) UFO packet will be submitted for transmission using driver xmit routine. UFO packet will have a non-zero value for "skb_shinfo(skb)->ufo_size" skb_shinfo(skb)->ufo_size will indicate the length of data part in each IP fragment going out of the adapter after IP fragmentation by hardware. skb->data will contain MAC/IP/UDP header and skb_shinfo(skb)->frags[] contains the data payload. The skb->ip_summed will be set to CHECKSUM_HW indicating that hardware has to do checksum calculation. Hardware should compute the UDP checksum of complete datagram and also ip header checksum of each fragmented IP packet. For IPV6 the UFO provides the fragment identification-id in skb_shinfo(skb)->ip6_frag_id. The adapter should use this ID for generating IPv6 fragments.

UDP Fragmentation Offload (UFO) Interface: ------------------------------------------- UFO is a feature wherein the Linux kernel network stack will offload the IP fragmentation functionality of large UDP datagram to hardware. This will reduce the overhead of stack in fragmenting the large UDP datagram to MTU sized packets 1) Drivers indicate their capability of UFO using dev->features |= NETIF_F_UFO | NETIF_F_HW_CSUM | NETIF_F_SG NETIF_F_HW_CSUM is required for UFO over ipv6. 2) UFO packet will be submitted for transmission using driver xmit routine. UFO packet will have a non-zero value for "skb_shinfo(skb)->ufo_size" skb_shinfo(skb)->ufo_size will indicate the length of data part in each IP fragment going out of the adapter after IP fragmentation by hardware. skb->data will contain MAC/IP/UDP header and skb_shinfo(skb)->frags[] contains the data payload. The skb->ip_summed will be set to CHECKSUM_HW indicating that hardware has to do checksum calculation. Hardware should compute the UDP checksum of complete datagram and also ip header checksum of each fragmented IP packet. For IPV6 the UFO provides the fragment identification-id in skb_shinfo(skb)->ip6_frag_id. The adapter should use this ID for generating IPv6 fragments.

/* NETIF_F_RXCSUM */ "rx-checksum",
net: Allow no-cache copy from user on transmit This patch uses __copy_from_user_nocache on transmit to bypass data cache for a performance improvement. skb_add_data_nocache and skb_copy_to_page_nocache can be called by sendmsg functions to use this feature, initial support is in tcp_sendmsg. This functionality is configurable per device using ethtool. Presumably, this feature would only be useful when the driver does not touch the data. The feature is turned on by default if a device indicates that it does some form of checksum offload; it is off by default for devices that do no checksum offload or indicate no checksum is necessary. For the former case copy-checksum is probably done anyway, in the latter case the device is likely loopback in which case the no cache copy is probably not beneficial. This patch was tested using 200 instances of netperf TCP_RR with 1400 byte request and one byte reply. Platform is 16 core AMD x86. No-cache copy disabled: 672703 tps, 97.13% utilization 50/90/99% latency:244.31 484.205 1028.41 No-cache copy enabled: 702113 tps, 96.16% utilization, 50/90/99% latency 238.56 467.56 956.955 Using 14000 byte request and response sizes demonstrate the effects more dramatically: No-cache copy disabled: 79571 tps, 34.34 %utlization 50/90/95% latency 1584.46 2319.59 5001.76 No-cache copy enabled: 83856 tps, 34.81% utilization 50/90/95% latency 2508.42 2622.62 2735.88 Note especially the effect on latency tail (95th percentile). This seems to provide a nice performance improvement and is consistent in the tests I ran. Presumably, this would provide the greatest benfits in the presence of an application workload stressing the cache and a lot of transmit data happening.

net: Allow ethtool to set interface in loopback mode. This patch enables ethtool to set the loopback mode on a given interface. By configuring the interface in loopback mode in conjunction with a policy route / rule, a userland application can stress the egress / ingress path exposing the flows of the change in progress and potentially help developer(s) understand the impact of those changes without even sending a packet out on the network. Following set of commands illustrates one such example - a) ip -4 addr add 192.168.1.1/24 dev eth1 b) ip -4 rule add from all iif eth1 lookup 250 c) ip -4 route add local 0/0 dev lo proto kernel scope host table 250 d) arp -Ds 192.168.1.100 eth1 e) arp -Ds 192.168.1.200 eth1 f) sysctl -w net.ipv4.ip_nonlocal_bind=1 g) sysctl -w net.ipv4.conf.all.accept_local=1 # Assuming that the machine has 8 cores h) taskset 000f netserver -L 192.168.1.200 i) taskset 00f0 netperf -t TCP_CRR -L 192.168.1.100 -H 192.168.1.200 -l 30 Signed-off-by: Mahesh Bandewar <maheshb@google.com> Acked-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S.

net: clear heap allocations for privileged ethtool actions Several other ethtool functions leave heap uncleared (potentially) by drivers. Some interfaces appear safe (eeprom, etc), in that the sizes are well controlled. In some situations (e.g. unchecked error conditions), the heap will remain unchanged in areas before copying back to userspace. Note that these are less of an issue since these all require CAP_NET_ADMIN.

ethtool: Add reset operation After updating firmware stored in flash, users may wish to reset the relevant hardware and start the new firmware immediately. This should not be completely automatic as it may be disruptive. A selective reset may also be useful for debugging or diagnostics. This adds a separate reset operation which takes flags indicating the components to be reset. Drivers are allowed to reset only a subset of those requested, and must indicate the actual subset. This allows the use of generic component masks and some future expansion. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

ethtool: EEPROM dump no longer works for tg3 and natsemi In the ethtool user-space application, tg3 and natsemi over-ride the default implementation of dump_eeprom(). In both tg3_dump_eeprom() and natsemi_dump_eeprom(), there is a magic number check which is not present in the default implementation. Commit b131dd5d ("[ETHTOOL]: Add support for large eeproms") snipped the code which copied the ethtool_eeprom structure back to user-space. tg3 and natsemi are over-writing the magic number field and then checking it in user-space. With the ethtool_eeprom copy removed, the check is failing. The fix is simple. Add the ethtool_eeprom copy back. Signed-off-by: Mandeep Singh Baines <msb@google.com> Signed-off-by: David S.

[IPv4/IPv6]: UFO Scatter-gather approach Attached is kernel patch for UDP Fragmentation Offload (UFO) feature. 1. This patch incorporate the review comments by Jeff Garzik. 2. Renamed USO as UFO (UDP Fragmentation Offload) 3. udp sendfile support with UFO This patches uses scatter-gather feature of skb to generate large UDP datagram. Below is a "how-to" on changes required in network device driver to use the UFO interface. UDP Fragmentation Offload (UFO) Interface: ------------------------------------------- UFO is a feature wherein the Linux kernel network stack will offload the IP fragmentation functionality of large UDP datagram to hardware. This will reduce the overhead of stack in fragmenting the large UDP datagram to MTU sized packets 1) Drivers indicate their capability of UFO using dev->features |= NETIF_F_UFO | NETIF_F_HW_CSUM | NETIF_F_SG NETIF_F_HW_CSUM is required for UFO over ipv6. 2) UFO packet will be submitted for transmission using driver xmit routine. UFO packet will have a non-zero value for "skb_shinfo(skb)->ufo_size" skb_shinfo(skb)->ufo_size will indicate the length of data part in each IP fragment going out of the adapter after IP fragmentation by hardware. skb->data will contain MAC/IP/UDP header and skb_shinfo(skb)->frags[] contains the data payload. The skb->ip_summed will be set to CHECKSUM_HW indicating that hardware has to do checksum calculation. Hardware should compute the UDP checksum of complete datagram and also ip header checksum of each fragmented IP packet. For IPV6 the UFO provides the fragment identification-id in skb_shinfo(skb)->ip6_frag_id. The adapter should use this ID for generating IPv6 fragments.

[IPv4/IPv6]: UFO Scatter-gather approach Attached is kernel patch for UDP Fragmentation Offload (UFO) feature. 1. This patch incorporate the review comments by Jeff Garzik. 2. Renamed USO as UFO (UDP Fragmentation Offload) 3. udp sendfile support with UFO This patches uses scatter-gather feature of skb to generate large UDP datagram. Below is a "how-to" on changes required in network device driver to use the UFO interface. UDP Fragmentation Offload (UFO) Interface: ------------------------------------------- UFO is a feature wherein the Linux kernel network stack will offload the IP fragmentation functionality of large UDP datagram to hardware. This will reduce the overhead of stack in fragmenting the large UDP datagram to MTU sized packets 1) Drivers indicate their capability of UFO using dev->features |= NETIF_F_UFO | NETIF_F_HW_CSUM | NETIF_F_SG NETIF_F_HW_CSUM is required for UFO over ipv6. 2) UFO packet will be submitted for transmission using driver xmit routine. UFO packet will have a non-zero value for "skb_shinfo(skb)->ufo_size" skb_shinfo(skb)->ufo_size will indicate the length of data part in each IP fragment going out of the adapter after IP fragmentation by hardware. skb->data will contain MAC/IP/UDP header and skb_shinfo(skb)->frags[] contains the data payload. The skb->ip_summed will be set to CHECKSUM_HW indicating that hardware has to do checksum calculation. Hardware should compute the UDP checksum of complete datagram and also ip header checksum of each fragmented IP packet. For IPV6 the UFO provides the fragment identification-id in skb_shinfo(skb)->ip6_frag_id. The adapter should use this ID for generating IPv6 fragments.

ethtool: allow custom interval for physical identification When physical identification of an adapter is done by toggling the mechanism on and off through software utilizing the set_phys_id operation, it is done with a fixed duration for both on and off states. Some drivers may want to set a custom duration for the on/off intervals. This patch changes the API so the return code from the driver's entry point when it is called with ETHTOOL_ID_ACTIVE can specify the frequency at which to cycle the on/off states, and updates the drivers that have already been converted to use the new set_phys_id and use the synchronous method for identifying an adapter. The physical identification frequency set in the updated drivers is based on how it was done prior to the introduction of set_phys_id. Compile tested only.

ethtool: Change ETHTOOL_PHYS_ID implementation to allow dropping RTNL The ethtool ETHTOOL_PHYS_ID command runs for an arbitrarily long period of time, holding the RTNL lock. This blocks routing updates, device enumeration, and various important operations that one might want to keep running while hunting for the flashing LED. We need to drop the RTNL lock during this operation, but currently the core implementation is a thin wrapper around a driver operation and drivers may well depend upon holding the lock. Define a new driver operation 'set_phys_id' with an argument that sets the ID indicator on/off/inactive/active (the last optional, for any driver or firmware that prefers to handle blinking asynchronously). When this is defined, the ethtool core drops the lock while waiting and only acquires it around calls to this operation. Deprecate the 'phys_id' operation in favour of this. It can be removed once all in-tree drivers are converted. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com>

ethtool: allow custom interval for physical identification When physical identification of an adapter is done by toggling the mechanism on and off through software utilizing the set_phys_id operation, it is done with a fixed duration for both on and off states. Some drivers may want to set a custom duration for the on/off intervals. This patch changes the API so the return code from the driver's entry point when it is called with ETHTOOL_ID_ACTIVE can specify the frequency at which to cycle the on/off states, and updates the drivers that have already been converted to use the new set_phys_id and use the synchronous method for identifying an adapter. The physical identification frequency set in the updated drivers is based on how it was done prior to the introduction of set_phys_id. Compile tested only.

net/ethtool: Add support for the ethtool feature to flash firmware image from a specified file. This patch adds support to flash a firmware image to a device using ethtool. The driver gets the filename of the firmware image and flashes the image using the request firmware path. The region "on the chip" to be flashed can be specified by an option. It is upto the device driver to enumerate the region number passed by ethtool, to the region to be flashed. The default behavior is to flash all the regions on the chip.

[NET]: Make the device list and device lookups per namespace. 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.

ethtool: allow non-netadmin to query settings The SNMP daemon uses ethtool to determine the speed of network interfaces. This fails on Debian (and probably elsewhere) because for security SNMP daemon runs as non-root user (snmp). Note: A similar patch was rejected previously because of a concern about the possibility that on some hardware querying the ethtool settings requires access to the PHY and could slow the machine down. But the security risk of requiring SNMP daemon (and related services) to run as root far out weighs the risk of denial-of-service.

Since user-space may still be using the old structure definition for the ETHTOOL_{G,S}RXFH commands, and since they do not need the additional fields, only copy the originally defined fields to and from user-space.

net/ethtool: Add support for the ethtool feature to flash firmware image from a specified file. This patch adds support to flash a firmware image to a device using ethtool. The driver gets the filename of the firmware image and flashes the image using the request firmware path. The region "on the chip" to be flashed can be specified by an option. It is upto the device driver to enumerate the region number passed by ethtool, to the region to be flashed. The default behavior is to flash all the regions on the chip.

ethtool: Add reset operation After updating firmware stored in flash, users may wish to reset the relevant hardware and start the new firmware immediately. This should not be completely automatic as it may be disruptive. A selective reset may also be useful for debugging or diagnostics. This adds a separate reset operation which takes flags indicating the components to be reset. Drivers are allowed to reset only a subset of those requested, and must indicate the actual subset. This allows the use of generic component masks and some future expansion. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net>

ethtool: Introduce n-tuple filter programming support This patchset enables the ethtool layer to program n-tuple filters to an underlying device. The idea is to allow capable hardware to have static rules applied that can assist steering flows into appropriate queues.

ethtool: Add support for control of RX flow hash indirection Many NICs use an indirection table to map an RX flow hash value to one of an arbitrary number of queues (not necessarily a power of 2). It can be useful to remove some queues from this indirection table so that they are only used for flows that are specifically filtered there. It may also be useful to weight the mapping to account for user processes with the same CPU-affinity as the RX interrupts.

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

default:
[NET]: ethtool ops are the only way During the transition to the ethtool_ops way of doing things, we supported calling the device's ->do_ioctl method to allow unconverted drivers to continue working. Those days are long behind us, all in-tree drivers use the ethtool_ops way, and so we no longer need to support this. The bonding driver is the biggest beneficiary of this; it no longer needs to call ioctl() as a fallback if ethtool_ops aren't supported. Also put a proper copyright statement on ethtool.c.
