2010-09-29staging: android: lowmemorykiller: Remove bitrotted codepathSan Mehat
Now that we're murder-synchronous, this code path will never be called (and if it does, it doesn't tell us anything useful other than we killed a task that was already being killed by somebody else but hadn't gotten its' signal yet) Signed-off-by: San Mehat <san@google.com>
2010-09-29staging: android: lowmemorykiller: Fix task_struct leakSan Mehat
As it turns out, the CONFIG_PROFILING interfaces leak a task struct if the notifier chain returns NOTIFY_OK.. doh. This patch reworks lowmemkiller to use the new generic task free notifier chain. Signed-off-by: San Mehat <san@google.com>
2010-09-29binder: Fix memory corruption via page aliasingChristopher Lais
binder_deferred_release was not unmapping the page from the buffer before freeing it, causing memory corruption. This only happened when page(s) had not been freed by binder_update_page_range, which properly unmaps the pages. This only happens on architectures with VIPT aliasing. To reproduce, create a program which opens, mmaps, munmaps, then closes the binder very quickly. This should leave a page allocated when the binder is released. When binder_deferrred_release is called on the close, the page will remain mapped to the address in the linear proc->buffer. Later, we may map the same physical page to a different virtual address that has different coloring, and this may cause aliasing to occur. PAGE_POISONING will greatly increase your chances of noticing any problems. Change-Id: I6941bf212881b8bf846bdfda43d3609c7ae4892e Signed-off-by: Christopher Lais <chris+android@zenthought.org>
2010-09-29staging: android: lowmemkiller: Substantially reduce overhead during reclaimSan Mehat
This patch optimizes lowmemkiller to not do any work when it has an outstanding kill-request. This greatly reduces the pressure on the task_list lock (improving interactivity), as well as improving the vmscan performance when under heavy memory pressure (by up to 20x in tests). Note: For this enhancement to work, you need CONFIG_PROFILING Signed-off-by: San Mehat <san@google.com>
2010-09-29USB: android gadget: mass storage: Fix format issue for Vista HostVelempati Chiranjeevi
As part of formating the mass storage device, Host sends the INQUIRY scsi command. As per the standard, the command length for this command should be 6 bytes, whereas the Vista host sends 12 bytes. When the command length of the command is not equal to the standard length, the device sends a phase error as part of the status phase. When the host receives a phase error, it re-enumerates, hence the error. If the command is INQUIRY, and the command length is 12 bytes, treating this as a good command and not sending the phase error to the host fixes this issue.

2010-09-29lowmemorykiller: Don't try to kill the same pid over and overSan Mehat
Under certain circumstances, a process can take awhile to handle a sig-kill (especially if it's in a scheduler group with a very low share ratio). When this occurs, lowmemkiller returns to vmscan indicating the process memory has been freed - even though the process is still waiting to die. Since the memory hasn't actually freed, lowmemkiller is called again shortly after, and picks the same process to die; regardless of the fact that it has already been 'scheduled' to die and the memory has already been reported to vmscan as having been freed. Solution is to check fatal_signal_pending() on the selected task, and if it's already pending destruction return; indicating to vmscan that no resources were freed on this pass.

2010-09-29USB: gadget: f_mass_storage: Defer handling interface changes until it is safe.Mike Lockwood
Pulling in some code from file_storage.c, we now handle interface changes in do_set_config(), which is now not called until any pending requests have been successfully completed or cancelled. This fixes a race condition that resulted in usb_ep_free_request() being called while the request is still busy. Signed-off-by: Mike Lockwood <lockwood@android.com>

2010-09-29net: PPPoPNS and PPPoLAC fixes.Chia-chi Yeh
net: Fix a bitmask in PPPoPNS and rename constants in PPPoPNS and PPPoLAC. Signed-off-by: Chia-chi Yeh <chiachi@android.com> net: Fix a potential deadlock while releasing PPPoLAC/PPPoPNS socket. PPP driver guarantees that no thread will be executing start_xmit() after returning from ppp_unregister_channel(). To achieve this, a spinlock (downl) is used. In pppolac_release(), ppp_unregister_channel() is called after sk_udp is locked. At the same time, another thread might be running in pppolac_xmit() with downl. Thus a deadlock will occur if the thread tries to lock sk_udp. The same situation might happen on sk_raw in pppopns_release(). Signed-off-by: Chia-chi Yeh <chiachi@android.com> net: Force PPPoLAC and PPPoPNS to bind an interface before creating PPP channel. It is common to manipulate the routing table after configuring PPP device. Since both PPPoLAC and PPPoPNS run over IP, care must be taken to make sure that there is no loop in the routing table. Although this can be done by adding a host route, it might still cause problems when the interface is down for some reason. To solve this, this patch forces both drivers to bind an interface before creating PPP channel, so the system will not re-route the tunneling sockets to another interface when the original one is down. Another benefit is that now the host route is no longer required, so there is no need to remove it when PPP channel is closed. Signed-off-by: Chia-chi Yeh <chiachi@android.com> net: Avoid sleep-inside-spinlock in PPPoLAC and PPPoPNS. Since recv() and xmit() are called with a spinlock held, routines which might sleep cannot be used. This issue is solved by following changes: Incoming packets are now processed in backlog handler, recv_core(), instead of recv(). Since backlog handler is always executed with socket spinlock held, the requirement of ppp_input() is still satisfied. Outgoing packets are now processed in workqueue handler, xmit_core(), instead of xmit(). Note that kernel_sendmsg() is no longer used to prevent touching dead sockets. In release(), lock_sock() and pppox_unbind_sock() ensure that no thread is in recv_core() or xmit(). Then socket handlers are restored before release_sock(), so no packets will leak in backlog queue.
