11 years agonet: Add compat support for getsockopt (MCAST_MSFILTER)
David L Stevens [Tue, 29 Apr 2008 10:23:22 +0000]
net: Add compat support for getsockopt (MCAST_MSFILTER)

This patch adds support for getsockopt for MCAST_MSFILTER for
both IPv4 and IPv6. It depends on the previous setsockopt patch,
and uses the same method.

11 years agonet: Several cleanups for the setsockopt compat support.
David L Stevens [Tue, 29 Apr 2008 10:23:00 +0000]
net: Several cleanups for the setsockopt compat support.

1) added missing "__user" for kgsr and kgf pointers
2) verify read for only GROUP_FILTER_SIZE(0). The group_filter
        structure definition (via RFC) includes space for one source
        in the source list array, but that source need not be present.
        So, sizeof(group_filter) > GROUP_FILTER_SIZE(0). Fixed
        the user read-check for minimum length to use the smaller size.
3) remove unneeded "&" for gf_slist addresses

11 years agobridge: kernel panic when unloading bridge module
Bodo Stroesser [Tue, 29 Apr 2008 10:18:13 +0000]
bridge: kernel panic when unloading bridge module

There is a race condition when unloading bridge and netfilter.

The problem happens if __fake_rtable is in use by a skb
coming in, while someone starts to unload bridge.ko.
br_netfilter_fini() is called at the beginning of unload
in br_deinit() while skbs still are being forwarded and
transferred to local ip stack. Thus there is a possibility
of the __fake_rtable pointer not being removed in a skb that
goes up to ip stack. This results in a kernel panic, as
ip_rcv() calls the input-function of __fake_rtable, which
is NULL.

Moving the call of br_netfilter_fini() to the end of
br_deinit() solves the problem.

EIP: [<c04ccdfc>] skb_over_panic+0x5c/0x60 SS:ESP 0068:f6015bf8

Looking at the code, I ended up in nfq_mangle() function (called by
nfqnl_recv_verdict()) which performs a call to skb_copy_expand() due to
the increased size of data passed to the function. AFAICT, it should ask
for 'diff' instead of 'diff - skb_tailroom(e->skb)'. Because the
resulting sk_buff has not enough space to support the skb_put(skb, diff)
call a few lines later, this results in the call to skb_over_panic().

The patch below asks for allocation of a copy with enough space for
mangled packet and the same amount of headroom as old sk_buff. While
looking at how the regression appeared (e2b58a67), I noticed the same
pattern in ipq_mangle_ipv6() and ipq_mangle_ipv4(). The patch corrects
those locations too.

Tested with bigger reinjected IPv6 packets (nfqnl_mangle() path), things
are ok (2.6.25 and today's net-2.6 git tree).

TBIPA needs to be set to a value (on connected MDIO buses) that
doesn't conflict with PHYs on the bus.  By hardcoding it to 0x1f,
we were preventing boards with PHYs at 0x1f from working properly.
Instead, scan the bus when it comes up, and find an address that
doesn't have a PHY on it.  The TBI PHY configuration code then
trusts that the value in TBIPA is either safe, or doesn't matter
(ie - it's not an active bus with other PHYs).

From: Evgeniy Polyakov <johnpol@2ka.mipt.ru>

This fixes a regression added by ec3c0982a2dd1e671bad8e9d26c28dcba0039d87
("[TCP]: TCP_DEFER_ACCEPT updates - process as established")

tcp_v6_do_rcv()->tcp_rcv_established(), the latter goes to step5, where
eventually skb can be freed via tcp_data_queue() (drop: label), then if
check for tcp_defer_accept_check() returns true and thus
tcp_rcv_established() returns -1, which forces tcp_v6_do_rcv() to jump
to reset: label, which in turn will pass through discard: label and free
the same skb again.

Herbert Xu [Sun, 27 Apr 2008 07:59:59 +0000]
[IPSEC]: Use digest_null directly for auth

Previously digest_null had no setkey function which meant that
we used hmac(digest_null) for IPsec since IPsec always calls
setkey.  Now that digest_null has a setkey we no longer need to
do that.

In fact when only confidentiality is specified for ESP we already
use digest_null directly.  However, when the null algorithm is
explicitly specified by the user we still opt for hmac(digest_null).

This patch removes this discrepancy.  I have not added a new compat
name for it because by chance it wasn't actualy possible for the user
to specify the name hmac(digest_null) due to a key length check in
xfrm_user (which I found out when testing that compat name :)

[netdrvr] typhoon: typhoon_resume - remove call to start_queue

While trying to fix http://bugzilla.kernel.org/show_bug.cgi?id=8952
I looked at a few other drivers to figure out what drivers _should_
be doing for suspend/resume. I noticed typhoon driver is likely doing
more than it needs to.  Patch below is untested since I don't have the HW.

Suspend/resume code across NIC drivers is fairly inconsistent.
And I couldn't find any documentation on what the canonical sequence
NICs need to do for suspend or resume.  Is there any?

Barring contrary advice, I'm going model the tulip suspend/resume
fixes after tg3.c since a number of "modern" (< 5 years old) laptops
have that and I'm silly enough to assume it works.

ibm_newemac: PowerPC 440EP/440GR EMAC PHY clock workaround

This patch adds ibm_newemac PHY clock workaround for 440EP/440GR EMAC
attached to a PHY which doesn't generate RX clock if there is no link.
The code is based on the previous ibm_emac driver stuff. The 440EP/440GR
allows controlling each EMAC clock separately as opposed to global clock
selection for 440GX.

BenH: Made that #ifdef CONFIG_PPC_DCR_NATIVE for now as dcri_* stuff doesn't
exist for MMIO type DCRs like Cell. Some future rework & improvements of the
DCR infrastructure will make that cleaner but for now, this makes it work.

ibm_newemac: PowerPC 440GX EMAC PHY clock workaround

The PowerPC 440GX Taishan board fails to reset EMAC3 (reset timeout
error) if there's no link. Because of that it fails to find PHY
chip. The older ibm_emac driver had a workaround for that: the
EMAC_CLK_INTERNAL/EMAC_CLK_EXTERNAL macros, which toggle the Ethernet
Clock Select bit in the SDR0_MFR register. This patch does the same for
"ibm,emac-440gx" compatible chips. The workaround forces clock on -all-
EMACs, so we select clock under global emac_phy_map_lock.

tcp: tcp_probe buffer overflow and incorrect return value

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.
