diff-CVE-2005-2709-sysctl-unreg
[PATCH] CVE-2005-2709 sysctl unregistration oops
You could open the /proc/sys/net/ipv4/conf/<if>/<whatever> file, then wait for interface to go away, try to grab as much memory as possible in hope to hit the (kfreed) ctl_table. Then fill it with pointers to your function. Then do read from file you've opened and if you are lucky, you'll get it called as ->proc_handler() in kernel mode. So this is at least an Oops and possibly more. It does depend on an interface going away though, so less of a security risk than it would otherwise be.
diff-ms-stopmachine-ipi-deadlock
This patch fixes deadlock of stop_machine() vs. synchronous IPI send. The problem is that stop_machine() disables interrupts before disabling preemption on other CPUs. So if another CPU is preempted and then calls something like flush_tlb_all() it will deadlock with CPU doing stop_machine() and which can't process IPI due to disabled IRQs.
I changed stop_machine() to do the same things exactly as it does on other CPUs, i.e. it should disable preemption first on _all_ CPUs including itself and only after that disable IRQs.
diff-ubc-oom-fix-20051102
- shrinked slabs counting during try_to_free_pages() (lost from 2.4);
- do not call yield() in oom_kill() if suicide hapened (lost from 2.4);
- oom_kill_counter correct calculations when task is set to be PF_MEMDIE-d oom_kill_counter must be incremented, when this task calls do_exit() - oom_kill_counter decrements. this logic was broken before;
- code cleanups.
diff-ms-pagealloc-nofail-20051108
When PF_MEMALLOC is set __alloc_pages() does it best to allocate a page. If even this try fails it is not good to immediately return NULL - try to wait longer.
Bug 44254.
diff-ve-ia64-fsyscalls-20051103
- fsys_getpid needs new offset for tgid;
- fsys_getppid must not be called via fsys (locking);
- fsys_set_tid_address needs new offset for pid.
diff-ve-ia64-printk-20051010
Some info-printk can be triggered by userspace process. No need to spoil main logbuf.
diff-ubc-ia64-pgfaultoom-20051108
Ported i386 page fault OOM logic to ia64
diff-ubc-emt64-pgfaultoom-20051108
Ported i386 OOM logic in page fault to x86-64.

diff-ubc-resnames-20051107
Print ubc resource name, not just number in __charge_beancounter_locked() when resource is run out.
diff-ve-ia64-printk-20051103
Unaligned accesses in userspace are handled with kernel exception handler and appropriate printk() occurs. This printk must go to VE's log.
diff-ve-ip-conntrack-natmodrefs-20051031
fixed iptable_nat module reference counting
diff-ve-ip-conntrack-modrefs-20051031
If we have custom iptables entries inside VPS, than on VPS stop related iptable_* modules counts decrements aren't performed. Fixed.
diff-ve-ia64-vpids-20051103
- sys32_ptrace searches task by pid (must by vpid);
- signal handling functions send signal by pid (must by vpid).
diff-ve-emt64-kernelthread-20051103
diff-ve-ia64-kernelthread-20051103
diff-schedule-taskstopped-20050919
Patches from Pavel and Alexander:
Do not alow stopped tasks sleep if they have pending SIGKILL
Bug 50052.
diff-ms-setmempolicy-20051031
A kernel BUG() is triggered by a call to set_mempolicy() with a negative first argument. This is because the mode is declared as an int, and the validity check doesnt check < 0 values. Alternatively, mode could be declared as unsigned int or unsigned long.

diff-ia64-headers-20051101
This patch makes ia64 kernel compile.
diff-fairsched-balance-20051102
This patch adds passive/active balancing in CPU scheduler.
Additionally:
- doesn't drop rq->lock in schedule_vcpu() on fast path (same VCPU)
- introduced 5ms VCPU to PCPU affinity
- fixed initialization of VCPUs and scheduler domains
diff-ms-flock-hotplug-fix-20051114
The patch below fixes an interesting oddity we're seeing with fedora core development (where we recently started using udev heavily); basically right now filelock_init() is a module_init(), eg runs late. However that breaks down because there are earlier /sbin/hotplug callouts, which with udev, do locking operations. When that happens the kernel oopses because the slabs for file locks aren't initialized yet.
Solution: initialize this way early. It's only a kmem_cache_create after all, so can happen early.

Bug 54025.
diff-ve-vpid-alloc-20051118
[PATCH] vpid allocator was broken
alloc_pidmap sometimes returned 65536. I understood its logic incorreclty, apparently pid_max does not mean a strict limit on pid value, it just prescribes to allocate pid < pid_max, if there is at least one free value in this range.
Plus, it was suboptimal because nr_free never reached 0, so if we have all low pids allocated, it always will scan bitmap.
diff-proc-locks-fix-20051111
unregister_sysctl_table held sysctl_lock (spinlock) and called remove_proc_entry, which in turn tried to down_write some semaphore...
fixes bad interaction of:
- diff-CVE-2005-2709-sysctl-unreg
- diff-proc-locks-20050930
diff-fairsched-gcc4-20051114
fixing compilation issue of kernel/sched.c using gcc4.
diff-ubc-ia64-include-20051111
This patch adds forgotten by Pavel ub include in arch/ia64/mm/fault.c.
This issue appears after applying diff-ubc-hardsoft-cleanup-20051103 patch.
diff-ms-emt64-usercopy-20041020
[PATCH] x86_64: correct copy_user_generic return value when exception happens
Fix a bug that arch/x86_64/lib/copy_user:copy_user_generic will return a wrong value when exception happens.
In the case the address is not 8-byte aligned (i.e. go into Lbad_alignment), if exception happens in Ls11, %rdx will be wrong number of copied bytes, then copy_user_generic returns wrong value. It also fixed a bug of zeroing wrong number of bytes of destination at this situation. (In Lzero_rest)

diff-ve-legacyptys-20051111
fixed VPS operations when CONFIG_LEGACY_PTYS is not set
diff-ms-dethread-20051117
[PATCH] fix de_thread() vs send_group_sigqueue() race
When non-leader thread does exec, de_thread calls release_task(leader) before calling exit_itimers(). If local timer interrupt happens in between, it can oops in send_group_sigqueue() while taking ->sighand->siglock == NULL.
However, we can't change send_group_sigqueue() to check p->signal != NULL, because sys_timer_create() does get_task_struct() only in SIGEV_THREAD_ID case. So it is possible that this task_struct was already freed and we can't trust p->signal.
This patch changes de_thread() so that leader released after exit_itimers() call.

diff-ms-notifyparent-20051120
[PATCH] Don't auto-reap traced children
If a task is being traced we never auto-reap it even if it might look like its parent doesn't care. The tracer obviously _does_ care.

diff-ms-posix-lock-race
Fix close() vs posix lock race
A threaded app that posix-locks and closes the same file in two threads concurrently may result in a posix lock that was never visible to the closer, and that thus needs cleanup on the final fput. Handle it together with the regular flocks.
