2008-04-03[IPV6]: Fix refcounting for anycast dst entries.Denis V. Lunev1-7/+2
Anycast DST entries allocated inside ipv6_dev_ac_inc are leaked when network device is stopped without removing IPv6 addresses from it. The bug has been observed in the reality on 2.6.18-rhel5 kernel. In the above case addrconf_ifdown marks all entries as obsolete and ip6_del_rt called from __ipv6_dev_ac_dec returns ENOENT. The referrence is not dropped. The fix is simple. DST entry should not keep referrence when stored in the FIB6 tree. Signed-off-by: Denis V. Lunev <[email protected]> Signed-off-by: David S.

2008-04-03[IPV6]: Unify ip6_onlink() and ipip6_onlink().YOSHIFUJI Hideaki1-24/+1
Both are identical, let's create ipv6_chk_prefix() and use it in both places.

2008-01-28[NETNS][IPV6]: inet6_addr - check ipv6 address per namespaceDaniel Lezcano1-1/+1
When a new address is added, we must check if the new address does not already exists. This patch makes this check to be aware of a network namespace, so the check will look if the address already exists for the specified network namespace. While the addresses are browsed, the addresses which do not belong to the namespace are discarded.

2007-10-10[NET]: Make core networking code use seq_open_privatePavel Emelyanov1-18/+2
This concerns the ipv4 and ipv6 code mostly, but also the netlink and unix sockets. The netlink code is an example of how to use the __seq_open_private() call - it saves the net namespace on this private. Signed-off-by: Pavel Emelyanov <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2007-10-10[NET]: sparse warning fixesStephen Hemminger1-1/+1

2007-10-10[NET]: Make the device list and device lookups per namespace.Eric W. Biederman1-6/+6
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.

2007-10-10[NET]: Make /proc/net per network namespaceEric W. Biederman1-2/+3
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.

2007-05-03[NET]: Rework dev_base via list_head (v3)Pavel Emelianov1-7/+10
Cleanup of dev_base list use, with the aim to simplify making device list per-namespace. In almost every occasion, use of dev_base variable and dev->next pointer could be easily replaced by for_each_netdev loop. A few most complicated places were converted to using first_netdev()/next_netdev().

2007-02-28[IPV6]: /proc/net/anycast6 unbalanced inet6_dev refcntDavid Stevens1-0/+1

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau1-1/+0
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).

2007-02-12[PATCH] mark struct file_operations const 7Arjan van de Ven1-1/+1
Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

2005-06-21[IPV6]: V6 route events reported with wrong netlink PID and seq numberJamal Hadi Salim1-2/+2
Essentially netlink at the moment always reports a pid and sequence of 0 always for v6 route activities. To understand the repurcassions of this look at: http://lists.quagga.net/pipermail/quagga-dev/2005-June/003507.html While fixing this, i took the liberty to resolve the outstanding issue of IPV6 routes inserted via ioctls to have the correct pids as well. This patch tries to behave as close as possible to the v4 routes i.e maintains whatever PID the socket issuing the command owns as opposed to the process. That made the patch a little bulky. I have tested against both netlink derived utility to add/del routes as well as ioctl derived one. The Quagga folks have tested against quagga. This fixes the problem and so far hasnt been detected to introduce any new issues.

2005-04-16Linux-2.6.12-rc2Linus Torvalds1-0/+594
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!
