2009-02-11Do not account for hugetlbfs quota at mmap() time if mapping [SHM|MAP]_NORESERVEMel Gorman1-20/+33
Commit 5a6fe125950676015f5108fb71b2a67441755003 brought hugetlbfs more in line with the core VM by obeying VM_NORESERVE and not reserving hugepages for both shared and private mappings when [SHM|MAP]_NORESERVE are specified. However, it is still taking filesystem quota unconditionally. At fault time, if there are no reserves and attempt is made to allocate the page and account for filesystem quota. If either fail, the fault fails. The impact is that quota is getting accounted for twice. This patch partially reverts 5a6fe125950676015f5108fb71b2a67441755003.

In dasd_device_set_timer and dasd_block_set_timer we interpret the return value of mod_timer in a wrong way. If the timer expires in the small window between our check of timer_pending and the call to mod_timer, then the timer will be set, mod_timer returns zero and we will call add_timer for a timer that is already pending. As del_timer and mod_timer do all the necessary checking themselves, we can simplify our code and remove the race a the same time.

2009-02-11ptrace, x86: fix the usage of ptrace_fork()Oleg Nesterov1-1/+1
I noticed by pure accident we have ptrace_fork() and friends. This was added by "x86, bts: add fork and exit handling", commit bf53de907dfdaac178c92d774aae7370d7b97d20. I can't test this, ds_request_bts() returns -EOPNOTSUPP, but I strongly believe this needs the fix. I think something like this program int main(void) { int pid = fork(); if (!pid) { ptrace(PTRACE_TRACEME, 0, NULL, NULL); kill(getpid(), SIGSTOP); fork(); } else { struct ptrace_bts_config bts = { .flags = PTRACE_BTS_O_ALLOC, .size = 4 * 4096, }; wait(NULL); ptrace(PTRACE_SETOPTIONS, pid, NULL, PTRACE_O_TRACEFORK); ptrace(PTRACE_BTS_CONFIG, pid, &bts, sizeof(bts)); ptrace(PTRACE_CONT, pid, NULL, NULL); sleep(1); } return 0; } should crash the kernel. If the task is traced by its natural parent ptrace_reparented() returns 0 but we should clear ->btsxxx anyway.

2009-02-10Do not account for the address space used by hugetlbfs using VM_ACCOUNTMel Gorman8-43/+65
When overcommit is disabled, the core VM accounts for pages used by anonymous shared, private mappings and special mappings. It keeps track of VMAs that should be accounted for with VM_ACCOUNT and VMAs that never had a reserve with VM_NORESERVE. Overcommit for hugetlbfs is much riskier than overcommit for base pages due to contiguity requirements. It avoids overcommiting on both shared and private mappings using reservation counters that are checked and updated during mmap(). This ensures (within limits) that hugepages exist in the future when faults occurs or it is too easy to applications to be SIGKILLed. As hugetlbfs makes its own reservations of a different unit to the base page size, VM_ACCOUNT should never be set. Even if the units were correct, we would double account for the usage in the core VM and hugetlbfs. VM_NORESERVE may be set because an application can request no reserves be made for hugetlbfs at the risk of getting killed later. With commit fc8744adc870a8d4366908221508bb113d8b72ee, VM_NORESERVE and VM_ACCOUNT are getting unconditionally set for hugetlbfs-backed mappings. This breaks the accounting for both the core VM and hugetlbfs, can trigger an OOM storm when hugepage pools are too small lockups and corrupted counters otherwise are used. This patch brings hugetlbfs more in line with how the core VM treats VM_NORESERVE but prevents VM_ACCOUNT being set.

2009-02-10tracing, x86: fix fixup section to return to original codeSteven Rostedt1-3/+5
Impact: fix to prevent a kernel crash on fault If for some reason the pointer to the parent function on the stack takes a fault, the fix up code will not return back to the original faulting code. This can lead to unpredictable results and perhaps even a kernel panic. A fault should not happen, but if it does, we should simply disable the tracer, warn, and continue running the kernel. It should not lead to a kernel crash. Signed-off-by: Steven Rostedt <srostedt@redhat.com>

The new legacy_mem file in sysfs is causing problems with X on machines that don't support legacy memory access. The way I initially implemented it, we would fail with -ENXIO when trying to mmap it, thus exposing to X that we do support the API but there is no legacy memory. Unfortunately, X poor error handling is causing it to fail to start when it gets this error. This implements a workaround hack that instead maps anonymous memory instead (using shmem if VM_SHARED is set, just like /dev/zero does).

2009-02-10x86: fix math_emu register frame accessTejun Heo7-56/+55
do_device_not_available() is the handler for #NM and it declares that it takes a unsigned long and calls math_emu(), which takes a long argument and surprisingly expects the stack frame starting at the zero argument would match struct math_emu_info, which isn't true regardless of configuration in the current code. This patch makes do_device_not_available() take struct pt_regs like other exception handlers and initialize struct math_emu_info with pointer to it and pass pointer to the math_emu_info to math_emulate() like normal C functions do. This way, unless gcc makes a copy of struct pt_regs in do_device_not_available(), the register frame is correctly accessed regardless of kernel configuration or compiler used. This doesn't fix all math_emu problems but it at least gets it somewhat working. Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-02-09gianfar: Fix boot hangs while bringing up gianfar ethernetJarek Poplawski1-0/+6
Ira Snyder found that commit 8c7396aebb68994c0519e438eecdf4d5fa9c7844 "gianfar: Merge Tx and Rx interrupt for scheduling clean up ring" can cause hangs. It's because there was removed clearing of interrupts in gfar_schedule_cleanup() (which is called by an interrupt handler) in case when netif scheduling has been disabled. This patch brings back this action and a comment.

When user tries to map all chunks given in argument, kernel works on a copy of the chunkmap, but at the end it doesn't check the copy, but the orginal one.

2009-02-09netfilter: ctnetlink: fix echo if not subscribed to any multicast groupPablo Neira Ayuso1-2/+3
This patch fixes echoing if the socket that has sent the request to create/update/delete an entry is not subscribed to any multicast group. With the current code, ctnetlink would not send the echo message via unicast as nfnetlink_send() would be skip.

2009-02-09netfilter: ctnetlink: allow changing NAT sequence adjustment in creationPablo Neira Ayuso1-0/+10
This patch fixes an inconsistency in the current ctnetlink code since NAT sequence adjustment bit can only be updated but not set in the conntrack entry creation. This patch is used by conntrackd to successfully recover newly created entries that represent connections with helpers and NAT payload mangling.

2009-02-09netfilter: nf_conntrack_ipv6: don't track ICMPv6 negotiation messageEric Leblond1-0/+21
This patch removes connection tracking handling for ICMPv6 messages related to Stateless Address Autoconfiguration, MLD, and MLDv2. They can not be tracked because they are massively using multicast (on pre-defined address). But they are not invalid and should not be detected as such.

2009-02-09netfilter: fix tuple inversion for Node information requestEric Leblond1-2/+2
The patch fixes a typo in the inverse mapping of Node Information request. Following draft-ietf-ipngwg-icmp-name-lookups-09, "Querier" sends a type 139 (ICMPV6_NI_QUERY) packet to "Responder" which answer with a type 140 (ICMPV6_NI_REPLY) packet.

2009-02-09Btrfs: don't use spin_is_contendedChris Mason3-26/+1
Btrfs was using spin_is_contended to see if it should drop locks before doing extent allocations during btrfs_search_slot. The idea was to avoid expensive searches in the tree unless the lock was actually contended. But, spin_is_contended is specific to the ticket spinlocks on x86, so this is causing compile errors everywhere else. In practice, the contention could easily appear some time after we started doing the extent allocation, and it makes more sense to always drop the lock instead.
