2009-05-02r8169: Don't update statistics counters when interface is downFrancois Romieu
Upstream as 355423d0849f4506bc71ab2738d38cb74429aaef (post 2.6.28). Some Realtek chips (RTL8169sb/8110sb in my case) are unable to retrieve ethtool statistics when the interface is down. The process stays in endless loop in rtl8169_get_ethtool_stats. This is because these chips need to have receiver enabled (CmdRxEnb bit in ChipCmd register) that is cleared when the interface is going down. It's better to update statistics only when the interface is up and otherwise return copy of statistics grabbed when the interface was up (in rtl8169_close). It is interesting that PCI-E NICs (like 8168b/8111b...) are not affected. Signed-off-by: Ivan Vecera <ivecera@redhat.com> Acked-by: Francois Romieu <romieu@fr.zoreil.com> Signed-off-by: David S.

2009-05-02block: revert part of 18ce3751ccd488c78d3827e9f6bf54e6322676fbJens Axboe
commit 78f707bfc723552e8309b7c38a8d0cc51012e813 upstream. The above commit added WRITE_SYNC and switched various places to using that for committing writes that will be waited upon immediately after submission. However, this causes a performance regression with AS and CFQ for ext3 at least, since sync_dirty_buffer() will submit some writes with WRITE_SYNC while ext3 has sumitted others dependent writes without the sync flag set. This causes excessive anticipation/idling in the IO scheduler because sync and async writes get interleaved, causing a big performance regression for the below test case (which is meant to simulate sqlite like behaviour). ---- test case ---- int main(int argc, char **argv) { int fdes, i; FILE *fp; struct timeval start; struct timeval end; struct timeval res; gettimeofday(&start, NULL); for (i=0; i<ROWS; i++) { fp = fopen("test_file", "a"); fprintf(fp, "Some Text Data\n"); fdes = fileno(fp); fsync(fdes); fclose(fp); } gettimeofday(&end, NULL); timersub(&end, &start, &res); fprintf(stdout, "time to write %d lines is %ld(msec)\n", ROWS, (res.tv_sec*1000000 + res.tv_usec)/1000); return 0; } ------------------- Thanks to Sean.White@APCC.com for tracking down this performance regression and providing a test case.

upstream commit: 237e75bf1e558f7330f8deb167fa3116405bef2c The g_ether USB gadget driver currently decides whether or not there's a link to report back for eth_get_link based on if the USB link speed is set. The USB gadget speed is however often set even before the device is enumerated. It seems more sensible to only report a "link" if we're actually connected to a host that wants to talk to us.

2009-05-02powerpc: Fix data-corrupting bug in __futex_atomic_opPaul Mackerras
upstream commit: 306a82881b14d950d59e0b59a55093a07d82aa9a Richard Henderson pointed out that the powerpc __futex_atomic_op has a bug: it will write the wrong value if the stwcx. fails and it has to retry the lwarx/stwcx. loop, since 'oparg' will have been overwritten by the result from the first time around the loop. This happens because it uses the same register for 'oparg' (an input) as it uses for the result. This fixes it by using separate registers for 'oparg' and 'ret'.

2009-05-02add some long-missing capabilities to fs_maskSerge E. Hallyn
upstream commit: 0ad30b8fd5fe798aae80df6344b415d8309342cc When POSIX capabilities were introduced during the 2.1 Linux cycle, the fs mask, which represents the capabilities which having fsuid==0 is supposed to grant, did not include CAP_MKNOD and CAP_LINUX_IMMUTABLE. However, before capabilities the privilege to call these did in fact depend upon fsuid==0. This patch introduces those capabilities into the fsmask, restoring the old behavior. See the thread starting at http://lkml.org/lkml/2009/3/11/157 for reference. Note that if this fix is deemed valid, then earlier kernel versions (2.4 and 2.2) ought to be fixed too.

2009-05-02sched: do not count frozen tasks toward loadNathan Lynch
upstream commit: e3c8ca8336707062f3f7cb1cd7e6b3c753baccdd Freezing tasks via the cgroup freezer causes the load average to climb because the freezer's current implementation puts frozen tasks in uninterruptible sleep (D state). Some applications which perform job-scheduling functions consult the load average when making decisions. If a cgroup is frozen, the load average does not provide a useful measure of the system's utilization to such applications. This is especially inconvenient if the job scheduler employs the cgroup freezer as a mechanism for preempting low priority jobs. Contrast this with using SIGSTOP for the same purpose: the stopped tasks do not count toward system load. Change task_contributes_to_load() to return false if the task is frozen. This results in /proc/loadavg behavior that better meets users' expectations.

Make iscsi_pool_free more defensive. > Making the freeing of q->queue dependent on q->pool being set looks really weird (although it is correct at the moment. But this seems to be fixable in a much simpler way. With the benefit that only the error case is slowed down. In both cases we have a problem if q->queue contains an error value but it's not -ENOMEM.

upstream commit: f474a37bc48667595b5653a983b635c95ed82a3b Memory freeing in iscsi_pool_free() looks wrong to me. Either q->pool can be NULL and this should be tested before dereferencing it, or it can't be NULL and it shouldn't be tested at all. As far as I can see, the only case where q->pool is NULL is on early error in iscsi_pool_init(). One possible way to fix the bug is thus to not call iscsi_pool_free() in this case (nothing needs to be freed anyway) and then we can get rid of the q->pool check.

upstream commit: 7bfac9ecf0585962fe13584f5cf526d8c8e76f17 There's a possible deadlock in generic_file_splice_write(), splice_from_pipe() and ocfs2_file_splice_write(): - task A calls generic_file_splice_write() - this calls inode_double_lock(), which locks i_mutex on both pipe->inode and target inode - ordering depends on inode pointers, can happen that pipe->inode is locked first - __splice_from_pipe() needs more data, calls pipe_wait() - this releases lock on pipe->inode, goes to interruptible sleep - task B calls generic_file_splice_write(), similarly to the first - this locks pipe->inode, then tries to lock inode, but that is already held by task A - task A is interrupted, it tries to lock pipe->inode, but fails, as it is already held by task B - ABBA deadlock Fix this by explicitly ordering locks: the outer lock must be on target inode and the inner lock (which is later unlocked and relocked) must be on pipe->inode. This is OK, pipe inodes and target inodes form two nonoverlapping sets, generic_file_splice_write() and friends are not called with a target which is a pipe.

The maximum length that may be passed to the call to copy_to_user(buf+copied, xip_mem+offset, nr) is len-copied but the check only compares against (nr > len).

2009-05-02ipv6: Plug sk_buff leak in ipv6_rcv (net/ipv6/ip6_input.c)Jesper Nilsson
[ Upstream commit 71f6f6dfdf7c7a67462386d9ea05c1095a89c555 ] Commit 778d80be52699596bf70e0eb0761cf5e1e46088d (ipv6: Add disable_ipv6 sysctl to disable IPv6 operaion on specific interface) seems to have introduced a leak of sk_buff's for ipv6 traffic, at least in some configurations where idev is NULL, or when ipv6 is disabled via sysctl. The problem is that if the first condition of the if-statement returns non-NULL, it returns an skb with only one reference, and when the other conditions apply, execution jumps to the "out" label, which does not call kfree_skb for it. To plug this leak, change to use the "drop" label instead. (this relies on it being ok to call kfree_skb on NULL) This also allows us to avoid calling rcu_read_unlock here, and removes the only user of the "out" label.

[ Upstream commit cda6d377ec6b2ee2e58d563d0bd7eb313e0165df ] This fixes an crash when empty bond device is added to a bridge.

But the error unwind is broken, the bridge port object can get freed twice: once when ref count went to zeo, and once by kfree. Since object is never really accessible, just free it.

2009-05-02x86: mtrr: don't modify RdDram/WrDram bits of fixed MTRRsAndreas Herrmann
upstream commit: 3ff42da5048649503e343a32be37b14a6a4e8aaf Impact: bug fix + BIOS workaround BIOS is expected to clear the SYSCFG[MtrrFixDramModEn] on AMD CPUs after fixed MTRRs are configured. Some BIOSes do not clear SYSCFG[MtrrFixDramModEn] on BP (and on APs). This can lead to obfuscation in Linux when this bit is not cleared on BP but cleared on APs. A consequence of this is that the saved fixed-MTRR state (from BP) differs from the fixed-MTRRs of APs -- because RdDram/WrDram bits are read as zero when SYSCFG[MtrrFixDramModEn] is cleared -- and Linux tries to sync fixed-MTRR state from BP to AP. This implies that Linux sets SYSCFG[MtrrFixDramEn] and activates those bits. More important is that (some) systems change these bits in SMM when ACPI is enabled. Hence it is racy if Linux modifies RdMem/WrMem bits, too. (1) The patch modifies an old fix from Bernhard Kaindl to get suspend/resume working on some Acer Laptops. Bernhard's patch tried to sync RdMem/WrMem bits of fixed MTRR registers and that helped on those old Laptops. (Don't ask me why -- can't test it myself). But this old problem was not the motivation for the patch. (See http://lkml.org/lkml/2007/4/3/110) (2) The more important effect is to fix issues on some more current systems. On those systems Linux panics or just freezes, see http://bugzilla.kernel.org/show_bug.cgi?id=11541 (and also duplicates of this bug: http://bugzilla.kernel.org/show_bug.cgi?id=11737 http://bugzilla.kernel.org/show_bug.cgi?id=11714) The affected systems boot only using acpi=ht, acpi=off or when the kernel is built with CONFIG_MTRR=n. The acpi options prevent full enablement of ACPI. Obviously when ACPI is enabled the BIOS/SMM modfies RdMem/WrMem bits. When CONFIG_MTRR=y Linux also accesses and modifies those bits when it needs to sync fixed-MTRRs across cores (Bernhard's fix, see (1)). How do you synchronize that? You can't. As a consequence Linux shouldn't touch those bits at all (Rationale are AMD's BKDGs which recommend to clear the bit that makes RdMem/WrMem accessible). This is the purpose of this patch. And (so far) this suffices to fix (1) and (2). I suggest not to touch RdDram/WrDram bits of fixed-MTRRs and SYSCFG[MtrrFixDramEn] and to clear SYSCFG[MtrrFixDramModEn] as suggested by AMD K8, and AMD family 10h/11h BKDGs. BIOS is expected to do this anyway. This should avoid that Linux and SMM tread on each other's toes ...

The issue is with hardware which needs help conforming to part of the USB 2.0 spec (section 8.5.3.2); some can automagically send a ZLP in response to an unexpected IN, but not all chips will do that. We don't need to check the packet length ourselves the way earlier code did, since the UDC must already check it.

commit 6ff10464096540e14d7575a72c50d0316d003714 upstream. The usbfs driver manages a list of completed asynchronous URBs. But it is too eager to free the entries on this list: destroy_async() gets called whenever an interface is unbound or a device is removed, and it deallocates the outstanding struct async entries for all URBs on that interface or device. This is wrong; the user program should be able to reap an URB any time after it has completed, regardless of whether or not the interface is still bound or the device is still present. This patch (as1222) moves the code for deallocating the completed list entries from destroy_async() to usbdev_release(). The outstanding entries won't be freed until the user program has closed the device file, thereby eliminating any possibility that the remaining URBs might still be reaped. This fixes a bug in which a program can hang in the USBDEVFS_REAPURB ioctl when the device is unplugged.
