| * ipv4: annotate a few functions __init in ipconfig.cSam Ravnborg2008-04-291-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A few functions are only used from __init context. So annotate these with __init for consistency and silence the following warnings: WARNING: net/ipv4/built-in.o(.text+0x2a876): Section mismatch in reference from the function ic_bootp_init() to the variable .init.data:bootp_packet_type WARNING: net/ipv4/built-in.o(.text+0x2a907): Section mismatch in reference from the function ic_bootp_cleanup() to the variable .init.data:bootp_packet_type Note: The warnings only appear with CONFIG_DEBUG_SECTION_MISMATCH=y Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: David S.

| * netfilter: nf_conntrack: padding breaks conntrack hash on ARMPhilip Craig2008-04-292-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | commit 0794935e "[NETFILTER]: nf_conntrack: optimize hash_conntrack()" results in ARM platforms hashing uninitialised padding. This padding doesn't exist on other architectures. Fix this by replacing NF_CT_TUPLE_U_BLANK() with memset() to ensure everything is initialised. There were only 4 bytes that NF_CT_TUPLE_U_BLANK() wasn't clearing anyway (or 12 bytes on ARM). Signed-off-by: Philip Craig <philipc@snapgear.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes bug http://bugzilla.kernel.org/show_bug.cgi?id=10556 where conn templates with protocol=IPPROTO_IP can oops backup box. Result from ip_vs_proto_get() should be checked because protocol value can be invalid or unsupported in backup. But for valid message we should not fail for templates which use IPPROTO_IP.

| * bridge: kernel panic when unloading bridge moduleBodo Stroesser2008-04-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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).

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 :) Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

| * tcp: tcp_probe buffer overflow and incorrect return valueTom Quetchenbach2008-04-241-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * ethtool: EEPROM dump no longer works for tg3 and natsemiMandeep Singh Baines2008-04-241-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the ethtool user-space application, tg3 and natsemi over-ride the default implementation of dump_eeprom(). In both tg3_dump_eeprom() and natsemi_dump_eeprom(), there is a magic number check which is not present in the default implementation. Commit b131dd5d ("[ETHTOOL]: Add support for large eeproms") snipped the code which copied the ethtool_eeprom structure back to user-space. tg3 and natsemi are over-writing the magic number field and then checking it in user-space. With the ethtool_eeprom copy removed, the check is failing. The fix is simple. Add the ethtool_eeprom copy back. Signed-off-by: Mandeep Singh Baines <msb@google.com> Signed-off-by: David S.

| | * | SUNRPC: Invalidate the RPCSEC_GSS session if the server dropped the requestTrond Myklebust2008-04-241-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RFC 2203 requires the server to drop the request if it believes the RPCSEC_GSS context is out of sequence. The problem is that we have no way on the client to know why the server dropped the request. In order to avoid spinning forever trying to resend the request, the safe approach is therefore to always invalidate the RPCSEC_GSS context on every major timeout.

| | * | SUNRPC: Don't change the RPCSEC_GSS context on a credential that is in useTrond Myklebust2008-04-191-27/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a server rejects our credential with an AUTH_REJECTEDCRED or similar, we need to refresh the credential and then retry the request. However, we do want to allow any requests that are in flight to finish executing, so that we can at least attempt to process the replies that depend on this instance of the credential. The solution is to ensure that gss_refresh() looks up an entirely new RPCSEC_GSS credential instead of attempting to create a context for the existing invalid credential.

| | * | SUNRPC: Don't disconnect more than once if retransmitting NFSv4 requestsTrond Myklebust2008-04-193-2/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | NFSv4 requires us to ensure that we break the TCP connection before we're allowed to retransmit a request. However in the case where we're retransmitting several requests that have been sent on the same connection, we need to ensure that we don't interfere with the attempt to reconnect and/or break the connection again once it has been established. We therefore introduce a 'connection' cookie that is bumped every time a connection is broken. This allows requests to track if they need to force a disconnection.
