(I'm optimistic that disabling GPU semaphores is simply hiding another bug by the latency and side-effects of the additional device interaction it introduces...) However, use of semaphores is a massive performance improvement... Only as long as the system remains stable. Enable at your peril.

5c4b4be Andi Kleen 05 March 2011, 01:36:32 UTC mm: use correct numa policy node for transparent hugepages Pass down the correct node for a transparent hugepage allocation. Most callers continue to use the current node, however the hugepaged daemon now uses the previous node of the first to be collapsed page instead. This ensures that khugepaged does not mess up local memory for an existing process which uses local policy. The choice of node is somewhat primitive currently: it just uses the node of the first page in the pmd range. An alternative would be to look at multiple pages and use the most popular node. I used the simplest variant for now which should work well enough for the case of all pages being on the same node.

95b90af Thomas Gleixner 05 March 2011, 01:36:23 UTC pps: make pps_gen_parport depend on BROKEN This driver causes hard lockups, when the active clock soure is jiffies. The reason is that it loops with interrupts disabled waiting for a timestamp to be reached by polling getnstimeofday(). Though with a jiffies clocksource, when that code runs on the same CPU which is responsible for updating jiffies, then we loop in circles for ever simply because the timer interrupt cannot update jiffies. So both UP and SMP can be affected. There is no easy fix for that problem so make it depend on BROKEN for now.

We tracked this back to an nfsv4 setacl operation, in which the nfs code attempted to fill convert the passed in buffer to an array of pages in __nfs4_proc_set_acl, which gets used by the skb->frags list in xs_sendpages. __nfs4_proc_set_acl just converts each page in the buffer to a page struct via virt_to_page, but the vfs allocates the buffer via kmalloc, meaning the PG_slab bit is set. We can't create a buffer with kmalloc and free it later in the tcp ack path with put_page, so we need to either: 1) ensure that when we create the list of pages, no page struct has PG_Slab set or 2) not use a page list to send this data Given that these buffers can be multiple pages and arbitrarily sized, I think (1) is the right way to go. I've written the below patch to allocate a page from the buddy allocator directly and copy the data over to it. This ensures that we have a put_page free-able page for every entry that winds up on an skb frag list, so it can be safely freed when the frame is acked. We do a put page on each entry after the rpc_call_sync call so as to drop our own reference count to the page, leaving only the ref count taken by tcp_sendpages. This way the data will be properly freed when the ack comes in Successfully tested by myself to solve the above oops.

e00de34 Sage Weil 04 March 2011, 20:25:05 UTC libceph: fix msgr standby handling The standby logic used to be pretty dependent on the work requeueing behavior that changed when we switched to WQ_NON_REENTRANT. It was also very fragile. Restructure things so that: - We clear WRITE_PENDING when we set STANDBY. This ensures we will requeue work when we wake up later. - con_work backs off if STANDBY is set. There is nothing to do if we are in standby. - clear_standby() helper is called by both con_send() and con_keepalive(), the two actions that can wake us up again. Move the connect_seq++ logic here.

60bf8bf Sage Weil 04 March 2011, 20:24:28 UTC libceph: fix msgr backoff With commit f363e45f we replaced a bunch of hacky workqueue mutual exclusion logic with the WQ_NON_REENTRANT flag. One pieces of fallout is that the exponential backoff breaks in certain cases: * con_work attempts to connect. * we get an immediate failure, and the socket state change handler queues immediate work. * con_work calls con_fault, we decide to back off, but can't queue delayed work. In this case, we add a BACKOFF bit to make con_work reschedule delayed work next time it runs (which should be immediately). Signed-off-by: Sage Weil <sage@newdream.net> 04 March 2011, 20:24:28 UTC

1362fa0 David Howells 03 March 2011, 11:28:58 UTC DNS: Fix a NULL pointer deref when trying to read an error key [CVE-2011-1076] When a DNS resolver key is instantiated with an error indication, attempts to read that key will result in an oops because user_read() is expecting there to be a payload - and there isn't one [CVE-2011-1076]. Give the DNS resolver key its own read handler that returns the error cached in key->type_data.x[0] as an error rather than crashing. Also make the kenter() at the beginning of dns_resolver_instantiate() limit the amount of data it prints, since the data is not necessarily NUL-terminated. The buggy code was added in: commit 4a2d789267e00b5a1175ecd2ddefcc78b83fbf09 Author: Wang Lei <wang840925@gmail.com> Date: Wed Aug 11 09:37:58 2010 +0100 Subject: DNS: If the DNS server returns an error, allow that to be cached [ver #2] This can trivially be reproduced by any user with the following program compiled with -lkeyutils: #include <stdlib.h> #include <keyutils.h> #include <err.h> static char payload[] = "#dnserror=6"; int main() { key_serial_t key; key = add_key("dns_resolver", "a", payload, sizeof(payload), KEY_SPEC_SESSION_KEYRING); if (key == -1) err(1, "add_key"); if (keyctl_read(key, NULL, 0) == -1) err(1, "read_key"); return 0; } What should happen is that keyctl_read() reports error 6 (ENXIO) to the user: dns-break: read_key: No such device or address but instead the kernel oopses. This cannot be reproduced with the 'keyutils add' or 'keyutils padd' commands as both of those cut the data down below the NUL termination that must be included in the data. Without this dns_resolver_instantiate() will return -EINVAL and the key will not be instantiated such that it can be read. The oops looks like: BUG: unable to handle kernel NULL pointer dereference at 0000000000000010 IP: [<ffffffff811b99f7>] user_read+0x4f/0x8f PGD 3bdf8067 PUD 385b9067 PMD 0 Oops: 0000 [#1] SMP last sysfs file: /sys/devices/pci0000:00/0000:00:19.0/irq CPU 0 Modules linked in: Pid: 2150, comm: dns-break Not tainted 2.6.38-rc7-cachefs+ #468 /DG965RY RIP: 0010:[<ffffffff811b99f7>] [<ffffffff811b99f7>] user_read+0x4f/0x8f RSP: 0018:ffff88003bf47f08 EFLAGS: 00010246 RAX: 0000000000000001 RBX: ffff88003b5ea378 RCX: ffffffff81972368 RDX: 0000000000000000 RSI: 0000000000000000 RDI: ffff88003b5ea378 RBP: ffff88003bf47f28 R08: ffff88003be56620 R09: 0000000000000000 R10: 0000000000000395 R11: 0000000000000002 R12: 0000000000000000 R13: 0000000000000000 R14: 0000000000000000 R15: ffffffffffffffa1 FS: 00007feab5751700(0000) GS:ffff88003e000000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 0000000000000010 CR3: 000000003de40000 CR4: 00000000000006f0 DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 DR3: 0000000000000000 DR6: 00000000ffff0ff0 DR7: 0000000000000400 Process dns-break (pid: 2150, threadinfo ffff88003bf46000, task ffff88003be56090) Stack: ffff88003b5ea378 ffff88003b5ea3a0 0000000000000000 0000000000000000 ffff88003bf47f68 ffffffff811b708e ffff88003c442bc8 0000000000000000 00000000004005a0 00007fffba368060 0000000000000000 0000000000000000 Call Trace: [<ffffffff811b708e>] keyctl_read_key+0xac/0xcf [<ffffffff811b7c07>] sys_keyctl+0x75/0xb6 [<ffffffff81001f7b>] system_call_fastpath+0x16/0x1b Code: 75 1f 48 83 7b 28 00 75 18 c6 05 58 2b fb 00 01 be bb 00 00 00 48 c7 c7 76 1c 75 81 e8 13 c2 e9 ff 4c 8b b3 e0 00 00 00 4d 85 ed <41> 0f b7 5e 10 74 2d 4d 85 e4 74 28 e8 98 79 ee ff 49 39 dd 48 RIP [<ffffffff811b99f7>] user_read+0x4f/0x8f RSP <ffff88003bf47f08> CR2: 0000000000000010 Signed-off-by: David Howells <dhowells@redhat.com> Acked-by: Jeff Layton <jlayton@redhat.com> cc: Wang Lei <wang840925@gmail.com> Signed-off-by: James Morris <jmorris@namei.org> 03 March 2011, 22:56:19 UTC

16a8b70 Sage Weil 28 February 2011, 20:49:15 UTC ceph: do not clear I_COMPLETE from d_release First, this was racy anyway: d_release isn't called until well after the dentry is unhashed. Second, this runs afoul of the recent dcache change that clears d_parent prior to calling d_release (949854d0), causing a NULL pointer dereference.

0c2bd9b Martin Schwidefsky 03 March 2011, 16:56:07 UTC [S390] tape: deadlock on system work queue The 34xx and 3590 tape driver uses the system work queue to defer work from the interrupt function to process context, e.g. a medium sense after an unsolicited interrupt. The tape commands started by the work handler need to be asynchronous, otherwise a deadlock on the system work queue can occur.

2d3a849 Tao Ma 03 March 2011, 15:53:20 UTC blktrace: Remove blk_fill_rwbs_rq. If we enable trace events to trace block actions, We use blk_fill_rwbs_rq to analyze the corresponding actions in request's cmd_flags, but we only choose the minor 2 bits from it, so most of other flags(e.g, REQ_SYNC) are missing. For example, with a sync write we get: write_test-2409 [001] 160.013869: block_rq_insert: 3,64 W 0 () 258135 + = 8 [write_test] Since now we have integrated the flags of both bio and request, it is safe to pass rq->cmd_flags directly to blk_fill_rwbs and blk_fill_rwbs_rq isn't needed any more. With this patch, after a sync write we get: write_test-2417 [000] 226.603878: block_rq_insert: 3,64 WS 0 () 258135 += 8 [write_test] Signed-off-by: Tao Ma <boyu.mt@taobao.com> Acked-by: Jeff Moyer <jmoyer@redhat.com> Signed-off-by: Jens Axboe <jaxboe@fusionio.com> 03 March 2011, 15:53:20 UTC
