tcp_probe has a bounds-checking bug that causes many programs (less, python) to crash reading /proc/net/tcp_probe. When it outputs a log line to the reader, it only checks if that line alone will fit in the reader's buffer, rather than that line and all the previous lines it has already written. tcpprobe_read also returns the wrong value if copy_to_user fails--it just passes on the return value of copy_to_user (number of bytes not copied), which makes a failure look like a success. This patch fixes the buffer overflow and sets the return value to -EFAULT if copy_to_user fails. Patch is against latest net-2.6; tested briefly and seems to fix the crashes in less and python.

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.

Switch from formatting messages in probe routine and copying with kfifo, to using a small circular queue of information and formatting on read. This avoids wraparound issues with kfifo, and saves one copy. Also make sure to state correct license, rather than copying off some other driver I started with.

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.

In an effort to make kprobe modules more portable, here is a patch that: o Introduces the "symbol_name" field to struct kprobe. The symbol->address resolution now happens in the kernel in an architecture agnostic manner. 64-bit powerpc users no longer have to specify the ".symbols" o Introduces the "offset" field to struct kprobe to allow a user to specify an offset into a symbol. o The legacy mechanism of specifying the kprobe.addr is still supported. However, if both the kprobe.addr and kprobe.symbol_name are specified, probe registration fails with an -EINVAL. o The symbol resolution code uses kallsyms_lookup_name(). So CONFIG_KPROBES now depends on CONFIG_KALLSYMS o Apparantly kprobe modules were the only legitimate out-of-tree user of the kallsyms_lookup_name() EXPORT. Now that the symbol resolution happens in-kernel, remove the EXPORT as suggested by Christoph Hellwig o Modify tcp_probe.c that uses the kprobe interface so as to make it work on multiple platforms (in its earlier form, the code wouldn't work, say, on powerpc) Signed-off-by: NAnanth N Mavinakayanahalli <ananth@in.ibm.com> Signed-off-by: NPrasanna S Panchamukhi <prasanna@in.ibm.com> Signed-off-by: NChristoph Hellwig <hch@lst.de> Signed-off-by: NAndrew Morton <akpm@osdl.org> Signed-off-by: NLinus Torvalds <torvalds@osdl.org>
