The DLE handling in i4l-audio seems to be broken.
It produces spurious DLEs so asterisk 1.2.24 with chan_modem_i4l
gets irritated, the error message is:
"chan_modem_i4l.c:450 i4l_read: Value of escape is ^ (17)".
-> There shouldn't be a DLE-^.
If a spurious DLE-ETX occurs, the audio connection even dies.
I use a "AVM Fritz!PCI" isdn card.
I found two issues that only appear if ISDN_AUDIO_SKB_DLECOUNT(skb) > 0:
- The loop in isdn_tty.c:isdn_tty_try_read() doesn't escape a DLE if it's
the last character.
- The loop in isdn_common.c:isdn_readbchan_tty() doesn't copy its characters,
it only remembers the last one ("last = *p;").
Compare it with the loop in isdn_common.c:isdn_readbchan(), that *does*
copy them ("*cp++ = *p;") correctly.
The special handling of the "last" character made it more difficult.
I compared it to linux-2.4.19: There was no "last"-handling and both loops
did escape and copy all characters correctly.

The ISDN tty layer doesn't produce a 'NO CARRIER' message after hangup.
I suppose it broke when tty_buffer_flush() has been added to
tty_ldisc_flush() in the commit below.
For isdn_tty_modem_result(RESULT_NO_CARRIER..) the
message inserted via isdn_tty_at_cout() -> tty_insert_flip_char()
is flushed immediately by tty_ldisc_flush() -> tty_buffer_flush().
More annoyingly, the audio abort sequence DLE-ETX is also lost.
This patch fixes only active audio connections, because I assume that nobody
changes the line discipline for audio.
For non-audio connections the problem remains.
Maybe we can remove the tty_ldisc_flush() in isdn_tty_modem_result()
at all because it's done at tty_close?

Kernel panic - not syncing: Attempted to kill init!
The box has no HiSax card installed.
the reason for the crash is add_timer() done on an already running
timer. This happens because for some reason CARD_INIT is called twice.
this patch works this problem around by using mod_timer() - this gets
a booting system - but it would be nice to figure out why CARD_INIT
is done twice.

The patch
- Includes the call to capilib_data_b3_req in the spinlock. This routine
in turn calls the offending mq_enqueue routine that triggered the
freeze if not locked. This should also fix other indicators of
incosistent capilib_msgidqueue list, that trigger messages like:
Oct 5 03:05:57 BERL0 kernel: kcapi: msgid 3019 ncci 0x30301 not on queue
that we saw several times a day (usually several in a row).
- Fixes all occurrences of c4_dispatch_tx to be called with active
spinlock, there were some instances where no lock was active. Mostly
these are in very infrequently called routines, so the additional
performance penalty is minimal.

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.
