This gives the user vital diagnostics as to what is missing from their kernel. For example in the fragment below the kernel does not have CRAMFS compiled into the kernel and yet appears to recognise it at the RAMDISK detect stage. Later the mount fails as we don't have the filesystem. RAMDISK: cramfs filesystem found at block 0 RAMDISK: Loading 1604KiB [1 disk] into ram disk... done.

This avoids allocating a new page for COW if it's the last page. However, if CONFIG_SWAP is not set, can_share_swap_page() is defined as 0, thus always causes a copy for the last COW page.

41e5a6a Latchesar Ionkov 15 May 2006, 16:44:21 UTC [PATCH] v9fs: signal handling fixes Multiple races can happen when v9fs is interrupted by a signal and Tflush message is sent to the server. After v9fs sends Tflush it doesn't wait until it receives Rflush, and possibly the response of the original message. This behavior may confuse v9fs what fids are allocated by the file server.

48564e6 Jan Niehusmann 15 May 2006, 16:44:12 UTC [PATCH] smbfs: Fix slab corruption in samba error path Yesterday, I got the following error with 2.6.16.13 during a file copy from a smb filesystem over a wireless link. I guess there was some error on the wireless link, which in turn caused an error condition for the smb filesystem. In the log, smb_file_read reports error=4294966784 (0xfffffe00), which also shows up in the slab dumps, and also is -ERESTARTSYS. Error code 27499 corresponds to 0x6b6b, so the rq_errno field seems to be the only one being set after freeing the slab. In smb_add_request (which is the only place in smbfs where I found ERESTARTSYS), I found the following: if (!timeleft || signal_pending(current)) { /* * On timeout or on interrupt we want to try and remove the * request from the recvq/xmitq. */ smb_lock_server(server); if (!(req->rq_flags & SMB_REQ_RECEIVED)) { list_del_init(&req->rq_queue); smb_rput(req); } smb_unlock_server(server); } [...] if (signal_pending(current)) req->rq_errno = -ERESTARTSYS; I guess that some codepath like smbiod_flush() caused the request to be removed from the queue, and smb_rput(req) be called, without SMB_REQ_RECEIVED being set. This violates an asumption made by the quoted code. Then, the above code calls smb_rput(req) again, the req gets freed, and req->rq_errno = -ERESTARTSYS writes into the already freed slab. As list_del_init doesn't cause an error if called multiple times, that does cause the observed behaviour (freed slab with rq_errno=-ERESTARTSYS). If this observation is correct, the following patch should fix it. I wonder why the smb code uses list_del_init everywhere - using list_del instead would catch such situations by poisoning the next and prev pointers.

5e37661 Trent Piepho 15 May 2006, 16:44:06 UTC [PATCH] symbol_put_addr() locks kernel Even since a previous patch: Fix race between CONFIG_DEBUG_SLABALLOC and modules Sun, 27 Jun 2004 17:55:19 +0000 (17:55 +0000) http://www.kernel.org/git/?p=linux/kernel/git/torvalds/old-2.6-bkcvs.git;a=commit;h=92b3db26d31cf21b70e3c1eadc56c179506d8fbe The function symbol_put_addr() will deadlock the kernel. symbol_put_addr() would acquire modlist_lock, then while holding the lock call two functions kernel_text_address() and module_text_address() which also try to acquire the same lock. This deadlocks the kernel of course. This patch changes symbol_put_addr() to not acquire the modlist_lock, it doesn't need it since it never looks at the module list directly. Also, it now uses core_kernel_text() instead of kernel_text_address(). The latter has an additional check for addr inside a module, but we don't need to do that since we call module_text_address() (the same function kernel_text_address uses) ourselves.

The bug was identified by Jeff Moyer. The patch changes autofs4 to wait on expires only as this is all that's needed.

032ebf2 Linus Torvalds 13 May 2006, 01:42:09 UTC Alternative fix for MMC oops on unmount after removal Make sure to clear the driverfs_dev pointer when we do del_gendisk() (on disk removal), so that other users that may still have a ref to the disk won't try to use the stale pointer.

bd89efc Simon Kelley 12 May 2006, 21:56:08 UTC [NEIGH]: Fix IP-over-ATM and ARP interaction. The classical IP over ATM code maintains its own IPv4 <-> <ATM stuff> ARP table, using the standard neighbour-table code. The neigh_table_init function adds this neighbour table to a linked list of all neighbor tables which is used by the functions neigh_delete() neigh_add() and neightbl_set(), all called by the netlink code. Once the ATM neighbour table is added to the list, there are two tables with family == AF_INET there, and ARP entries sent via netlink go into the first table with matching family. This is indeterminate and often wrong. To see the bug, on a kernel with CLIP enabled, create a standard IPv4 ARP entry by pinging an unused address on a local subnet. Then attempt to complete that entry by doing ip neigh replace <ip address> lladdr <some mac address> nud reachable Looking at the ARP tables by using ip neigh show will reveal two ARP entries for the same address. One of these can be found in /proc/net/arp, and the other in /proc/net/atm/arp. This patch adds a new function, neigh_table_init_no_netlink() which does everything the neigh_table_init() does, except add the table to the netlink all-arp-tables chain. In addition neigh_table_init() has a check that all tables on the chain have a distinct address family. The init call in clip.c is changed to call neigh_table_init_no_netlink(). Since ATM ARP tables are rather more complicated than can currently be handled by the available rtattrs in the netlink protocol, no functionality is lost by this patch, and non-ATM ARP manipulation via netlink is rescued. A more complete solution would involve a rtattr for ATM ARP entries and some way for the netlink code to give neigh_add and friends more information than just address family with which to find the correct ARP table. [ I've changed the assertion checking in neigh_table_init() to not use BUG_ON() while holding neigh_tbl_lock. Instead we remember that we found an existing tbl with the same family, and after dropping the lock we'll give a diagnostic kernel log message and a stack dump. -DaveM ] Signed-off-by: Simon Kelley <simon@thekelleys.org.uk> Signed-off-by: David S.

Both Erik Mouw and Andrew Vasquez independently pinpointed this commit as causing problems, where the slab cache for a driver is never released (most obviously causing problems when immediately re-loading that driver, resulting in a "kmem_cache_create: duplicate cache <xyz>" message, but it can also cause other trouble). James Bottomley dug into it, and reports: "OK, here's the scoop. The problem patch adds a get of driverfs_dev in add_disk(), but doesn't put it again until disk_release() (which occurs on final put_disk() of the gendisk). However, in SCSI, the driverfs_dev is the sdev_gendev. That means there's a reference held on sdev_gendev until final disk put. Unfortunately, we use the driver model driver_remove to trigger del_gendisk (which removes the gendisk from visibility and decrements the refcount), so we've introduced an unbreakable deadlock in the reference counting with this. I suggest simply reversing this patch at the moment.

The bug is seen as a hung USB box and the kernel error: drivers/usb/misc/emi62.c: emi62_load_firmware - error loading firmware: error = -110 The patch below inserts a delay after deasserting reset to allow the box to settle before a new command is issued.

The patch adds an entry to mii_chip_info for the transceiver. The PHY ids were found using the sis900_c_122.diff patch from http://brownhat.org/sis900.html but that patch didn't solve the problem, because the PHY at address 1 was already being chosen. Without my patch, when bursts of packets arrive from other hosts on a LAN, the interface dropped one roughly 10% of the time, causing retransmits. There were fifth second pauses in refresh of large xterms, and it made Netrek suck. I can provide further test data. Workaround in lieu of patch is to use mii-tool to advertise 100baseTx-HD, then force renegotiation. I wasn't able to identify the actual transceiver, so the description field is a guess. This patch is similar to Artur Skawina's patch: http://marc.theaimsgroup.com/?l=linux-netdev&m=114297516729079&w=2 I'm not sure, but I wonder if it means the default behaviour should be changed, so as to better handle future transceivers.

6dd727d mdr@sgi.com 01 May 2006, 18:07:04 UTC [SCSI] mptfc: race between mptfc_register_dev and mptfc_target_alloc A race condition exists in mptfc between the thread registering a device with the fc transport and the scan work generated by the transport. This race existed prior to the application of the mptfc bug fix patch. mptfc_register_dev() calls fc_remote_port_add() with the FC_RPORT_ROLE_TARGET bit set in the rport ids passed to the function. Having this bit set causes fc_remote_port_add() to schedule a scan of the device. This scan can execute before mptfc_register_dev() can fill in the dd_data in the rport structure. When this happens, mptfc_target_alloc() will fail because dd_data is null. Attached is a patch which fixes the problem. The patch changes the rport ids passed to fc_remote_port_add() to not have the TARGET bit set. This prevents the scan from being scheduled. After mptfc_register_dev() fills in the rport dd_data field, fc_remote_port_rolechg() is called, changing the role of the rport to TARGET. Thus, the scan is scheduled after dd_data is filled in which prevents the failure in mptfc_target_alloc().

The specification states that the bit can be cleared by writing a 1 to it, but under certain circumstances it is possible for this bit to not clear. Writing a 0 to the bit resets the internal state machine and clears the issue. Since all writable bits in ACBST are W1C bits (write-one-to-clear) the second write doesn't affect any other logic except the buggy NEGACK state machine. The second write clears an internal register which is responsible for "overwriting" the NEGACK bit in ACBST.

a3285aa Roland Dreier 09 May 2006, 17:50:29 UTC IB/mthca: Fix race in reference counting Fix races in in destroying various objects. If a destroy routine waits for an object to become free by doing wait_event(&obj->wait, !atomic_read(&obj->refcount)); /* now clean up and destroy the object */ and another place drops a reference to the object by doing if (atomic_dec_and_test(&obj->refcount)) wake_up(&obj->wait); then this is susceptible to a race where the wait_event() and final freeing of the object occur between the atomic_dec_and_test() and the wake_up(). And this is a use-after-free, since wake_up() will be called on part of the already-freed object. Fix this in mthca by replacing the atomic_t refcounts with plain old integers protected by a spinlock. This makes it possible to do the decrement of the reference count and the wake_up() so that it appears as a single atomic operation to the code waiting on the wait queue. While touching this code, also simplify mthca_cq_clean(): the CQ being cleaned cannot go away, because it still has a QP attached to it. So there's no reason to be paranoid and look up the CQ by number; it's perfectly safe to use the pointer that the callers already have.

d945e1d Roland Dreier 09 May 2006, 17:50:28 UTC IB/srp: Fix tracking of pending requests during error handling If a SCSI abort completes, or the command completes successfully, then the driver must remove the command from its queue of pending commands. Similarly, if a device reset succeeds, then all commands queued for the given device must be removed from the queue. Signed-off-by: Roland Dreier <rolandd@cisco.com> 09 May 2006, 17:50:28 UTC
