* libcutils: qtaguid: Support new functions, add tag resource tracking.JP Abgrall2011-09-141-22/+132
| | | | | | | | | | | | | | | | | | | | | | | * Add support for deleteTagData(tag, uid) setCounterSet(counterSetNum, uid) setPacifier(on) * Add resource tracking (If only kernel process termination had a hook) Because the xt_qtaguid netfilter module needs to keep track of tagged sockets, it needs a way to know when the process owning the socket has died. Normally the app will untag the sockets. But not on crash. So the process opens the qtaguid misc dev, which is closed on crash, at which point the xt_qtaguid can force-untag the processes sockets, and thus allowing their refcount to go down and release them. * Add pacifier support Add function to enable/disable pacification of the xt_qtaguid kernel module. (mostly for debugging) Change-Id: I7f2228e65208046dd37ec1c7407ee307d5ba9b99

* | | Try to unmount writable filesystems when rebootingKen Sumrall2011-03-102-1/+135
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | Ext4 filesystems like to be unmounted before rebooting. The Android system doesn't have a traditional Linux init setup, and shutting down the system was not much more than calling sync(2) and reboot(2). This adds a new function to libcutils called android_reboot(). By default, it calls sync() and then remounts all writable filesystems as read-only and marks them clean. There is a flag parameter in which the caller can ask for sync() not to be called, or to not remount the filesystems as read-only. Then it will call reboot(2) as directed by the other parameters. This change also updates adb, init and toolbox to call the new android_reboot() function. Fixes bugs 3350709 and 3495575. Change-Id: I16d71ffce3134310d7a260f61ec6f4dd204124a7

Merged the pre- and post-ARMv6 implementations into a single file. Renamed the semi-private __android_membar_full_smp to USE_SCREAMING_CAPS since that's more appropriate for a macro.

* Atomic/SMP update.Andy McFadden2010-05-204-222/+46
| | | | | | | | | | | | | | | | | | | | | | | Added atomic-inline.h. Added a platform-specific memory barrier call there. Added android_atomic_acquire_cmpxchg() and android_atomic_release_store(). Not tested on Mac OS X or SH. Added memory barrier calls to linux-x86 atomics. Mac OS X has barrier functions already. sh isn't really SMP-ready. linux-arm needs work (to be done in a separate change). Updated the makefile to make the SMP state visible to the code here. Note that host binaries are NOT built with SMP enabled; while our hosts are very likely SMP, it's not worth figuring out e.g. whether it's okay to use the SSE2 mfence instruction or have to use something else. We haven't had barriers enabled in host tools before, so there's probably no need to stat now. Removed quasiatomic 64-bit calls (now part of Dalvik).

* More fixes to Binder perf regression from EclairBrad Fitzpatrick2010-05-071-32/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Re-use the file descriptor to change the cgroups. There's a fast path in the kernel for the case where the value's already uncahnged. Also, this is okay because the kernel ignores the write offset. This is essentially a ioctl-ish/datagram interface, despite being a fd we're writing to. This reduces Dalvik->Dalvik void/void Binder calls on Sapphire from ~1.2 to ~0.8 ms. This is a bit slower than the ~0.7 ms we get avoiding the write altogether. strace confirms: [pid 1557] ioctl(21, 0xc0186201 <unfinished ...> [pid 1556] <... ioctl resumed> , 0x45399cd0) = 0 [pid 1556] write(22, "1556", 4) = 4 [pid 1556] ioctl(21, 0xc0186201 <unfinished ...> [pid 1555] <... ioctl resumed> , 0x45299cd0) = 0 [pid 1555] write(22, "1555", 4) = 4 [pid 1555] ioctl(21, 0xc0186201 <unfinished ...> [pid 1554] <... ioctl resumed> , 0x45199cd0) = 0 [pid 1554] write(22, "1554", 4) = 4 BUG=2660235 Change-Id: Ia9f9e1d5b792eaebc9560f89931faf6df0cf9c0d
