cbc31a4 Andrew Morton 25 April 2007, 20:01:21 UTC packet: fix error handling The packet driver is assuming (reasonably) that the (undocumented) request.errors is an errno. But it is in fact some mysterious bitfield. When things go wrong we return weird positive numbers to the VFS as pointers and it goes oops. Thanks to William Heimbigner for reporting and diagnosis. (It doesn't oops, but this driver still doesn't work for William) Cc: William Heimbigner <icxcnika@mar.tar.cc> Cc: Peter Osterlund <petero2@telia.com> Cc: Jens Axboe <jens.axboe@oracle.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 25 April 2007, 20:50:55 UTC
1194ed0 Alexey Kuznetsov 25 April 2007, 20:07:28 UTC [NETLINK]: Infinite recursion in netlink. Reply to NETLINK_FIB_LOOKUP messages were misrouted back to kernel, which resulted in infinite recursion and stack overflow. The bug is present in all kernel versions since the feature appeared. The patch also makes some minimal cleanup: 1. Return something consistent (-ENOENT) when fib table is missing 2. Do not crash when queue is empty (does not happen, but yet) 3.

5044eed Jens Axboe 25 April 2007, 09:53:48 UTC cfq-iosched: fix alias + front merge bug There's a really rare and obscure bug in CFQ, that causes a crash in cfq_dispatch_insert() due to rq == NULL. One example of the resulting oops is seen here: http://lkml.org/lkml/2007/4/15/41 Neil correctly diagnosed the situation for how this can happen: if two concurrent requests with the exact same sector number (due to direct IO or aliasing between MD and the raw device access), the alias handling will add the request to the sortlist, but next_rq remains NULL. Read the more complete analysis at: http://lkml.org/lkml/2007/4/25/57 This looks like it requires md to trigger, even though it should potentially be possible to due with O_DIRECT (at least if you edit the kernel and doctor some of the unplug calls). The fix is to move the ->next_rq update to when we add a request to the rbtree. Then we remove the possibility for a request to exist in the rbtree code, but not have ->next_rq correctly updated.

c43c49b Dan Williams 24 April 2007, 14:20:06 UTC usb-net/pegasus: fix pegasus carrier detection Broken by 4a1728a28a193aa388900714bbb1f375e08a6d8e which switched the return semantics of read_mii_word() but didn't fix usage of read_mii_word() to conform to the new semantics. Setting carrier to off based on the NO_CARRIER flag is also incorrect as that flag only triggers on TX failure and therefore isn't correct when no frames are being transmitted. Since there is already a 2*HZ MII carrier check going on, defer to that. Add a TRUST_LINK_STATUS feature flag for adapters where the LINK_STATUS flag is actually correct, and use that rather than the NO_CARRIER flag.

b748d9e Neil Horman 20 April 2007, 13:54:58 UTC sis900: Allocate rx replacement buffer before rx operation The sis900 driver appears to have a bug in which the receive routine passes the skbuff holding the received frame to the network stack before refilling the buffer in the rx ring. If a new skbuff cannot be allocated, the driver simply leaves a hole in the rx ring, which causes the driver to stop receiving frames and become non-recoverable without an rmmod/insmod according to reporters. This patch reverses that order, attempting to allocate a replacement buffer first, and receiving the new frame only if one can be allocated. If no skbuff can be allocated, the current skbuf in the rx ring is recycled, dropping the current frame, but keeping the NIC operational.

d91c088 Andrea Righi 24 April 2007, 16:40:57 UTC [netdrvr] depca: handle platform_device_add() failure The following patch fixes a kernel bug in depca_platform_probe(). We don't use a dynamic pointer for pldev->dev.platform_data, so it seems that the correct way to proceed if platform_device_add(pldev) fails is to explicitly set the pldev->dev.platform_data pointer to NULL, before calling the platform_device_put(pldev), or it will be kfree'ed by platform_device_release().

9b7f375 Jeff Mahoney 23 April 2007, 21:41:17 UTC reiserfs: fix xattr root locking/refcount bug The listxattr() and getxattr() operations are only protected by a read lock. As a result, if either of these operations run in parallel, a race condition exists where the xattr_root will end up being cached twice, which results in the leaking of a reference and a BUG() on umount. This patch refactors get_xa_root(), __get_xa_root(), and create_xa_root(), into one get_xa_root() function that takes the appropriate locking around the entire critical section.

The patch adds an __attribute__((aligned(8))) to the taskstats structure members so that 32 bit applications using taskstats can work with a 64 bit kernel. Using __attribute__((packed)) would break the 64 bit alignment of members. The fix was tested on x86_64.

But other places in the kernel still assume SSE and do FXSAVE and the CPU will then access FXSAVE information with FNSAVE and cause corruption. Easiest way to avoid this is to remove the option.

Firstly, it may simply happen that the socket send queue was full at the time the request was initially sent through xprt_transmit(). Secondly, doing this for each request that was retransmitted implies that we disconnect and reconnect for _every_ request that happened to be retransmitted irrespective of whether or not a disconnection has already occurred. Fix is to move this logic into the call_status request timeout handler.

It has been reported by Valerie Clement <valerie.clement@bull.net> and the Intel testing folks. The regression is because of CFQ's now more aggressive queue control, limiting the depth available to the device.

1d464c2 Dave Johnson 18 April 2007, 14:39:41 UTC [MIPS] Fix wrong checksum for split TCP packets on 64-bit MIPS I've traced down an off-by-one TCP checksum calculation error under the following conditions: 1) The TCP code needs to split a full-sized packet due to a reduced MSS (typically due to the addition of TCP options mid-stream like SACK). _AND_ 2) The checksum of the 2nd fragment is larger than the checksum of the original packet. After subtraction this results in a checksum for the 1st fragment with bits 16..31 set to 1. (this is ok) _AND_ 3) The checksum of the 1st fragment's TCP header plus the previously 32bit checksum of the 1st fragment DOES NOT cause a 32bit overflow when added together. This results in a checksum of the TCP header plus TCP data that still has the upper 16 bits as 1's. _THEN_ 4) The TCP+data checksum is added to the checksum of the pseudo IP header with csum_tcpudp_nofold() incorrectly (the bug). The problem is the checksum of the TCP+data is passed to csum_tcpudp_nofold() as an 32bit unsigned value, however the assembly code acts on it as if it is a 64bit unsigned value. This causes an incorrect 32->64bit extension if the sum has bit 31 set. The resulting checksum is off by one. This problems is data and TCP header dependent due to #2 and #3 above so it doesn't occur on every TCP packet split.

It's been linked to lockups of the e1000 hardware, see for example https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=229603 but it's likely that the commit itself is not really introducing the bug, but just allowing an unrelated problem to rear its ugly head (ie one current working theory is that the code exposes us to a hardware race condition by decreasing the amount of time we spend in each NAPI poll cycle).

Arguably that's wrong since PPP protocol 0xff is reserved, and the RFC does envision the possibility of receiving frames where the control field has values other than 0x03. Signed-off-by: David S.

33bdeec Linas Vepstas 17 April 2007, 05:54:13 UTC spidernet: Fix problem sending IP fragments The basic structure of "normal" UDP/IP/Ethernet frames (that actually work): - It starts with the Ethernet header (dest MAC, src MAC, etc.) - The next part is occupied by the IP header (version info, length of packet, id=0, fragment offset=0, checksum, from / to address, etc.) - Then comes the UDP header (src / dest port, length, checksum) - Actual payload - Ethernet checksum Now what's different for IP fragment: - The IP header has id set to some value (same for all fragments), offset is set appropriately (i.e. 0 for first fragment, following according to size of other fragments), size is the length of the frame. - UDP header is unchanged. I.e. length is according to full UDP datagram, not just the part within the actual frame! But this is only true within the first frame: all following frames don't have a valid UDP-header at all. The spidernet silicon seems to be quite intelligent: It's able to compute (IP / UDP / Ethernet) checksums on the fly and tests if frames are conforming to RFC -- at least conforming to RFC on complete frames. But IP fragments are different as explained above: I.e. for IP fragments containing part of a UDP datagram it sees incompatible length in the headers for IP and UDP in the first frame and, thus, skips this frame. But the content *is* correct for IP fragments. For all following frames it finds (most probably) no valid UDP header at all. But this *is* also correct for IP fragments. The Linux IP-stack seems to be clever in this point. It expects the spidernet to calculate the checksum (since the module claims to be able to do so) and marks the skb's for "normal" frames accordingly (ip_summed set to CHECKSUM_HW). But for the IP fragments it does not expect the driver to be capable to handle the frames appropriately. Thus all checksums are allready computed. This is also flaged within the skb (ip_summed set to CHECKSUM_NONE). Unfortunately the spidernet driver ignores that hints. It tries to send the IP fragments of UDP datagrams as normal UDP/IP frames. Since they have different structure the silicon detects them the be not "well-formed" and skips them. The following one-liner against 2.6.21-rc2 changes this behavior. If the IP-stack claims to have done the checksumming, the driver should not try to checksum (and analyze) the frame but send it as is.

But when writing to the upper guest pde we also need to truncate the lower bits, otherwise the multiply shifts these bits into the pde index and causes an access to the wrong shadow pde.

bfb6709 Olaf Kirch 18 April 2007, 22:07:22 UTC [IrDA]: Correctly handling socket error This patch fixes an oops first reported in mid 2006 - see http://lkml.org/lkml/2006/8/29/358 The cause of this bug report is that when an error is signalled on the socket, irda_recvmsg_stream returns without removing a local wait_queue variable from the socket's sk_sleep queue. This causes havoc further down the road. In response to this problem, a patch was made that invoked sock_orphan on the socket when receiving a disconnect indication. This is not a good fix, as this sets sk_sleep to NULL, causing applications sleeping in recvmsg (and other places) to oops. This is against the latest net-2.6 and should be considered for -stable inclusion.

d0cf0d9 Vlad Yasevich 18 April 2007, 21:11:06 UTC [SCTP]: Do not interleave non-fragments when in partial delivery The way partial delivery is currently implemnted, it is possible to intereleave a message (either from another steram, or unordered) that is not part of partial delivery process. The only way to this is for a message to not be a fragment and be 'in order' or unorderd for a given stream. This will result in bypassing the reassembly/ordering queues where things live duing partial delivery, and the message will be delivered to the socket in the middle of partial delivery. This is a two-fold problem, in that: 1. the app now must check the stream-id and flags which it may not be doing. 2. this clearing partial delivery state from the association and results in ulp hanging. This patch is a band-aid over a much bigger problem in that we don't do stream interleave. Signed-off-by: Vlad Yasevich <vladislav.yasevich@hp.com> Signed-off-by: David S.
