This change causes several problems, first reported by Ingo Molnar as a distcc-over-loopback regression where connections were getting stuck. Ilpo Järvinen first spotted the locking problems. The new function added by this code, tcp_defer_accept_check(), only has the child socket locked, yet it is modifying state of the parent listening socket. Fixing that is non-trivial at best, because we can't simply just grab the parent listening socket lock at this point, because it would create an ABBA deadlock. The normal ordering is parent listening socket --> child socket, but this code path would require the reverse lock ordering. Next is a problem noticed by Vitaliy Gusev, he noted: ---------------------------------------- >--- a/net/ipv4/tcp_timer.c >+++ b/net/ipv4/tcp_timer.c >@@ -481,6 +481,11 @@ static void tcp_keepalive_timer (unsigned long data) > goto death; > } > >+ if (tp->defer_tcp_accept.request && sk->sk_state == TCP_ESTABLISHED) { >+ tcp_send_active_reset(sk, GFP_ATOMIC); >+ goto death; Here socket sk is not attached to listening socket's request queue. tcp_done() will not call inet_csk_destroy_sock() (and tcp_v4_destroy_sock() which should release this sk) as socket is not DEAD. Therefore socket sk will be lost for freeing. ---------------------------------------- Finally, Alexey Kuznetsov argues that there might not even be any real value or advantage to these new semantics even if we fix all of the bugs: ---------------------------------------- Hiding from accept() sockets with only out-of-order data only is the only thing which is impossible with old approach. Is this really so valuable? My opinion: no, this is nothing but a new loophole to consume memory without control. ---------------------------------------- So revert this thing for now.

The ipv4 part was fine, but the ipv6 part was not done correctly. Unlike the ipv4 side, the ipv6 code already has a .destroy method for rawv6_prot. So now there were two assignments to this member, and what the compiler does is use the last one, effectively making the ipv6 parts of that changeset a NOP. Fix this by removing the: .destroy = inet6_destroy_sock, line, and adding an inet6_destroy_sock() call to the end of raw6_destroy(). Noticed by Al Viro. Signed-off-by: David S.

| | * | net: Eliminate flush_scheduled_work() calls while RTNL is held.David S. Miller2008-06-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the RTNL is held when we invoke flush_scheduled_work() we could deadlock. One such case is linkwatch, it is a work struct which tries to grab the RTNL semaphore. The most common case are net driver ->stop() methods. The simplest conversion is to instead use cancel_{delayed_}work_sync() explicitly on the various work struct the driver uses. This is an OK transformation because these work structs are doing things like resetting the chip, restarting link negotiation, and so forth. And if we're bringing down the device, we're about to turn the chip off and reset it anways. So if we cancel a pending work event, that's fine here. Some drivers were working around this deadlock by using a msleep() polling loop of some sort, and those cases are converted to instead use cancel_{delayed_}work_sync() as well.

The smallest tabulated value of 10^6 * f(p) = sqrt(2*p/3) + 12 * sqrt(3*p/8) * (32 * p^3 + p) for p=0.0001 is 8172. Since this value is scaled by 10^6, the outcome of this bug is that a loss of 8172/10^6 = 0.8172% was reported whenever the input was below the table resolution of 0.01%. This means that the value was over 80 times too high, resulting in large spikes of the initial loss interval, thus unnecessarily reducing the throughput. Also corrected the printk format (%u for u32). Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk>
| | | * | | dccp ccid-2: Bug-Fix - Ack Vectors need to be ignored on request socketsGerrit Renker2008-06-11

The issue is that Ack Vectors must not be parsed on request sockets, since the Ack Vector feature depends on the selection of the (TX) CCID. During the initial handshake the CCIDs are undefined, and so RFC 4340, 10.3 applies: "Using CCID-specific options and feature options during a negotiation for the corresponding CCID feature is NOT RECOMMENDED [...]" And it is not even possible: when the server receives the Request from the client, the CCID and Ack vector features are undefined; when the Ack finalising the 3-way hanshake arrives, the request socket has not been cloned yet into a full socket. (This order is necessary, since otherwise the newly created socket would have to be destroyed whenever an option error occurred - a malicious hacker could simply send garbage options and exploit this.)

Such RTTs can be found e.g. when running CCID-3 over loopback. The fix removed a check against RTT < 4, but introduced a divide-by-zero bug. All steady-state RTTs in DCCP are filtered using dccp_sample_rtt(), which ensures non-zero samples. However, a zero RTT is possible on initialisation, when there is no RTT sample from the Request/Response exchange. The fix is to use the fallback-RTT from RFC 4340, 3.4. This is also better than just fixing update_win_count() since it allows other parts of the code to always assume that the RTT is non-zero during the time that the CCID is used.

This means the NAT extension is still in the bysource hash, causing a crash when walking over the hash chain the next time: BUG: unable to handle kernel paging request at 00120fbd IP: [<c03d394b>] nf_nat_setup_info+0x221/0x58a *pde = 00000000 Oops: 0000 [#1] PREEMPT SMP Pid: 2795, comm: conntrackd Not tainted (2.6.26-rc5 #1) EIP: 0060:[<c03d394b>] EFLAGS: 00010206 CPU: 1 EIP is at nf_nat_setup_info+0x221/0x58a EAX: 00120fbd EBX: 00120fbd ECX: 00000001 EDX: 00000000 ESI: 0000019e EDI: e853bbb4 EBP: e853bbc8 ESP: e853bb78 DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0068 Process conntrackd (pid: 2795, ti=e853a000 task=f7de10f0 task.ti=e853a000) Stack: 00000000 e853bc2c e85672ec 00000008 c0561084 63c1db4a 00000000 00000000 00000000 0002e109 61d2b1c3 00000000 00000000 00000000 01114e22 61d2b1c3 00000000 00000000 f7444674 e853bc04 00000008 c038e728 0000000a f7444674 Call Trace: [<c038e728>] nla_parse+0x5c/0xb0 [<c0397c1b>] ctnetlink_change_status+0x190/0x1c6 [<c0397eec>] ctnetlink_new_conntrack+0x189/0x61f [<c0119aee>] update_curr+0x3d/0x52 [<c03902d1>] nfnetlink_rcv_msg+0xc1/0xd8 [<c0390228>] nfnetlink_rcv_msg+0x18/0xd8 [<c0390210>] nfnetlink_rcv_msg+0x0/0xd8 [<c038d2ce>] netlink_rcv_skb+0x2d/0x71 [<c0390205>] nfnetlink_rcv+0x19/0x24 [<c038d0f5>] netlink_unicast+0x1b3/0x216 ...

Please either load one, or disable logging explicitly" was displayed for each logged packet when no userspace application is listening to nflog events. The message seems to warn for a problem with a kernel module missing but as said before this is not the case. I thus propose to suppress the message (I don't see any reason to flood the log because a user application has crashed.)

Fix a crash due to unitialized info->pseudo_palette. Put the framebuffer in the proper mode for software rendering. checkpatch cleanups. Hardware acceleration was removed when the driver was rewritten for the new framebuffer API in 2003. Software rendering requires a different framebuffer access mode but that wasn't changed. The driver now works again but is slow. The proper fix is to reintroduce hardware acceleration. Signed-off-by: Robert Reif <reif@earthlink.net> Signed-off-by: David S. Miller <davem@davemloft.net>

This driver provides only RTC functionality. This chip is met in lots of custom boards with AT91SAMXXXX CPU I work with, is cheap and in no way better or worse than any other RTC on market. While it is mostly met on much smaller devices, I think it is great to have it supported in Linux.

It turned out this is because I use pnpacpi=off kernel option to work around the parport_pc bugs. I always did so, but RTC used to work fine in the past, and now it have regressed. The patch fixes the problem by creating the platform device for the RTC when PNP is disabled. This may also help running the PNP-enabled kernel on an older PCs.

| * | | | | radix-tree: fix small lockless radix-tree bugNick Piggin2008-06-12

The child becomes the new root node. To perform this operation in a manner compatible with concurrent lockless lookups, we atomically switch the root pointer from the parent to its child. However a concurrent lockless lookup may now have loaded a pointer to the parent (and is presently deciding what to do next). For this reason, we also have to keep the parent node in a valid state after shrinking the tree, until the next RCU grace period -- otherwise this lookup with the parent pointer may not do the right thing. Notably, we need to keep the child in the left most slot there in case that is requested by the lookup. This is all pretty standard RCU stuff. It is worth repeating because in my eagerness to obey the radix tree node constructor scheme, I had broken it by zeroing the radix tree node before the grace period. What could happen is that a lookup can load the parent pointer, then decide it wants to follow the left most child slot, only to find the slot contained NULL due to the concurrent shrinker having zeroed the parent node before waiting for a grace period. The lookup would return a false negative as a result. Fix it by doing that clearing in the RCU callback. I would normally want to rip out the constructor entirely, but radix tree nodes are one of those places where they make sense (only few cachelines will be touched soon after allocation). This was never actually found in any lockless pagecache testing or by the test harness, but by seeing the odd problem with my scalable vmap rewrite. I have not tickled the test harness into reproducing it yet, but I'll keep working at it. Fortunately, it is not a problem anywhere lockless pagecache is used in mainline kernels (pagecache probe is not a guarantee, and brd does not have concurrent lookups and deletes).

This hid two format errors - shp->shm_segsz and shp->shm_nattach are both unsigned long, but were being printed as unsigned int and signed int respectively. This leads to 32-bit truncation of SHM segment sizes reported in /proc/sysvipc/shm. (And for nattach, but that's less of a problem for most users). This patch makes the format string directly visible to gcc's format specifier checker, and fixes the two broken format specifiers.
