This routine scans the ipv6_fl_list whose update is protected with the socket lock and the ip6_sk_fl_lock. Since the socket lock is not taken in the lookup, use the other one. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Signed-off-by: David S. Miller <davem@davemloft.net>

The new flowlabels should be inserted into the sock list under the ip6_sk_fl_lock. This was lost in one place. This list is naturally protected with the socket lock, but the fl6_sock_lookup() is called without it, so another protection is required.

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 <xemul@openvz.org> Signed-off-by: David S.

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.

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.

There's a bug in the seqfile show operation for flowlabel objects, where each hash chain is traversed cumulatively for each element. The following function is called for each element of each chain: static void ip6fl_fl_seq_show(struct seq_file *seq, struct ip6_flowlabel *fl) { while(fl) { seq_printf... fl = fl->next; } } Thus, objects can appear mutliple times when reading /proc/net/ip6_flowlabel, as the above is called for each element in the chain. The solution is to remove the while() loop from the above, and traverse each chain exactly once, per the patch below. This also removes the ip6fl_fl_seq_show() function, which does nothing else.

Currently, when an application requests a lease for a flowlabel via the IPV6_FLOWLABEL_MGR socket option, no error is returned if an invalid type of destination address is supplied as part of the request, leading to a silent failure. This patch ensures that EINVAL is returned to the application in this case. Signed-off-by: James Morris <jmorris@namei.org> Signed-off-by: David S. Miller <davem@davemloft.net>

There's a bug in the seqfile handling for /proc/net/ip6_flowlabel, where, after finding a flowlabel, the code will loop forever not finding any further flowlabels, first traversing the rest of the hash bucket then just looping. This patch fixes the problem by breaking after the hash bucket has been traversed. Note that this bug can cause lockups and oopses, and is trivially invoked by an unpriveleged user.

There are errors and inconsistency in the display of NIP6 strings. ie: net/ipv6/ip6_flowlabel.c There are errors and inconsistency in the display of NIPQUAD strings too. ie: net/netfilter/nf_conntrack_ftp.c This patch: adds NIP6_FMT to kernel.h changes all code to use NIP6_FMT fixes net/ipv6/ip6_flowlabel.c adds NIPQUAD_FMT to kernel.h fixes net/netfilter/nf_conntrack_ftp.c changes a few uses of "%u.%u.%u.%u" to NIPQUAD_FMT for symmetry to NIP6_FMT Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.

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!
