tcp: tcp_probe buffer overflow and incorrect return value

2008-04-25T04:11:58+00:00

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.

[NET]: Make /proc/net per network namespace

2007-10-10T23:49:06+00:00

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.

jprobes: remove JPROBE_ENTRY()

2007-07-19T17:04:44+00:00

AFAICT now that jprobe.entry is a void *, JPROBE_ENTRY doesn't do anything
useful - so remove it ..

I've left a do-nothing version so that out-of-tree jprobes code will still
compile without modifications.

[TCP]: tcp probe wraparound handling and other changes

2007-07-12T02:45:39+00:00

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.
