* [PATCH] md: make sure resync gets started when array starts.NeilBrown2005-08-23
| | | | | | | | | | | | | We weren't actually waking up the md thread after setting MD_RECOVERY_NEEDED when assembling an array, so it is possible to lose a race and not actually start resync. So add a call to md_wakeup_thread, and while we are at it, remove all the "if (mddev->thread)" guards as md_wake_thread does its own checking.

* [PATCH] preempt race in getppidDavid Meybohm2005-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With CONFIG_PREEMPT && !CONFIG_SMP, it's possible for sys_getppid to return a bogus value if the parent's task_struct gets reallocated after current->group_leader->real_parent is read: asmlinkage long sys_getppid(void) { int pid; struct task_struct *me = current; struct task_struct *parent; parent = me->group_leader->real_parent; RACE HERE => for (;;) { pid = parent->tgid; #ifdef CONFIG_SMP { struct task_struct *old = parent; /* * Make sure we read the pid before re-reading the * parent pointer: */ smp_rmb(); parent = me->group_leader->real_parent; if (old != parent) continue; } #endif break; } return pid; } If the process gets preempted at the indicated point, the parent process can go ahead and call exit() and then get wait()'d on to reap its task_struct. When the preempted process gets resumed, it will not do any further checks of the parent pointer on !CONFIG_SMP: it will read the bad pid and return. So, the same algorithm used when SMP is enabled should be used when preempt is enabled, which will recheck ->real_parent in this case.

| * [TCP]: Unconditionally clear TCP_NAGLE_PUSH in skb_entail().David S. Miller2005-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Intention of this bit is to force pushing of the existing send queue when TCP_CORK or TCP_NODELAY state changes via setsockopt(). But it's easy to create a situation where the bit never clears. For example, if the send queue starts empty: 1) set TCP_NODELAY 2) clear TCP_NODELAY 3) set TCP_CORK 4) do small write() The current code will leave TCP_NAGLE_PUSH set after that sequence. Unconditionally clearing the bit when new data is added via skb_entail() solves the problem. Signed-off-by: David S. Miller <davem@davemloft.net>
| * [PKT_SCHED]: Fix missing qdisc_destroy() in qdisc_create_dflt()Thomas Graf2005-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | qdisc_create_dflt() is missing to destroy the newly allocated default qdisc if the initialization fails resulting in leaks of all kinds. The only caller in mainline which may trigger this bug is sch_tbf.c in tbf_create_dflt_qdisc(). Note: qdisc_create_dflt() doesn't fulfill the official locking requirements of qdisc_destroy() but since the qdisc could never be seen by the outside world this doesn't matter and it can stay as-is until the locking of pkt_sched is cleaned up.

Breaks ROSE completly and AX.25 if UID policy set to deny. o While the list structure of AX.25's UID to callsign mapping table was properly protected by a spinlock, it's elements were not refcounted resulting in a race between removal and usage of an element.

| * [NET]: Fix socket bitop damageRalf Baechle2005-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The socket flag cleanups that went into 2.6.12-rc1 are basically oring the flags of an old socket into the socket just being created. Unfortunately that one was just initialized by sock_init_data(), so already has SOCK_ZAPPED set. As the result zapped sockets are created and all incoming connection will fail due to this bug which again was carefully replicated to at least AX.25, NET/ROM or ROSE. In order to keep the abstraction alive I've introduced sock_copy_flags() to copy the socket flags from one sockets to another and used that instead of the bitwise copy thing. Anyway, the idea here has probably been to copy all flags, so sock_copy_flags() should be the right thing. With this the ham radio protocols are usable again, so I hope this will make it into 2.6.13.

| * [IPV4]: Fix negative timer loop with lots of ipv4 peers.Dave Johnson2005-08-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From: Dave Johnson <djohnson+linux-kernel@sw.starentnetworks.com> Found this bug while doing some scaling testing that created 500K inet peers. peer_check_expire() in net/ipv4/inetpeer.c isn't using inet_peer_gc_mintime correctly and will end up creating an expire timer with less than the minimum duration, and even zero/negative if enough active peers are present. If >65K peers, the timer will be less than inet_peer_gc_mintime, and with >70K peers, the timer duration will reach zero and go negative. The timer handler will continue to schedule another zero/negative timer in a loop until peers can be aged. This can continue for at least a few minutes or even longer if the peers remain active due to arriving packets while the loop is occurring. Bug is present in both 2.4 and 2.6. Same patch will apply to both just fine. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | While I was going through the crypto users recently, I noticed this bogus kmap in sunrpc.

| | | | | | | | | | | | | | | | | | | | | | | | If the tail SKB fits into the window, it is still benefitical to defer until the goal percentage of the window is available.

| | | | | | | | | | | | | | | | | | | | | | | | Thanks to Stephane, we've now worked out the real cause of the `Linux will not boot on simulator' problem. Turns out it's a stack overflow because the stack pointer wasn't being initialised properly in boot_head.S (it was being initialised to the lowest instead of the highest address of the stack, so the first push started to overwrite data in the BSS).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main issue is that bus_fixup calls may potentially call functions that require a valid bus->sysdata pointer.

The tg3 driver mistakenly detects this NIC as having a SerDes PHY and link does not come up as a result. The problem was caused by an incorrectly programmed eeprom that set the NIC_SRAM_DATA_CFG_PHY_TYPE_FIBER bit in the NIC_SRAM_DATA_CFG location. This patch will override the NIC_SRAM_DATA_CFG_PHY_TYPE_FIBER bit if a valid PHY ID is read from the MII registers on older 570x chips where the MII interface is not used on SerDes chips. On newer chips such as the 5780 that use MII for both copper and SerDes, SerDes detection must rely on the eeprom. This patch will make the SerDes detection identical to versions 3.25 and older.
