That's wrong when Unix extensions are disabled because in this case a server doesn't follow the same semantic and returns the old value on the next QueryInfo request. As the result, we update our value with the server one and then decrement it on every rmdir call - go to negative nlink values.

This fixes an issue whose symptoms exactly match reports showing tp->sacked_out going negative since 3.3.0-rc4 (see "WARNING: at net/ipv4/tcp_input.c:3418" thread on netdev). Since 2008 (832d11c5cd076abc0aa1eaf7be96c81d1a59ce41) tcp_shift_skb_data() had been shifting SACKed ranges that were below snd_una. It checked that the *end* of the skb it was about to shift from was above snd_una, but did not check that the end of the actual shifted range was above snd_una; this commit adds that check. Shifting SACKed ranges below snd_una is problematic because for such ranges tcp_sacktag_one() short-circuits: it does not declare anything as SACKed and does not increase sacked_out. Before the fixes in commits cc9a672ee522d4805495b98680f4a3db5d0a0af9 and daef52bab1fd26e24e8e9578f8fb33ba1d0cb412, shifting SACKed ranges below snd_una happened to work because tcp_shifted_skb() was always (incorrectly) passing in to tcp_sacktag_one() an skb whose end_seq tcp_shift_skb_data() had already guaranteed was beyond snd_una. Hence tcp_sacktag_one() never short-circuited and always increased tp->sacked_out in this case. After those two fixes, my testing has verified that shifting SACKed ranges below snd_una could cause tp->sacked_out to go negative with the following sequence of events: (1) tcp_shift_skb_data() sees an skb whose end_seq is beyond snd_una, then shifts a prefix of that skb that is below snd_una (2) tcp_shifted_skb() increments the packet count of the already-SACKed prev sk_buff (3) tcp_sacktag_one() sees the end of the new SACKed range is below snd_una, so it short-circuits and doesn't increase tp->sacked_out (5) tcp_clean_rtx_queue() sees the SACKed skb has been ACKed, decrements tp->sacked_out by this "inflated" pcount that was missing a matching increase in tp->sacked_out, and hence tp->sacked_out underflows to a u32 like 0xFFFFFFFF, which casted to s32 is negative. (6) this leads to the warnings seen in the recent "WARNING: at net/ipv4/tcp_input.c:3418" thread on the netdev list; e.g.: tcp_input.c:3418 WARN_ON((int)tp->sacked_out < 0); More generally, I think this bug can be tickled in some cases where two or more ACKs from the receiver are lost and then a DSACK arrives that is immediately above an existing SACKed skb in the write queue. This fix changes tcp_shift_skb_data() to abort this sequence at step (1) in the scenario above by noticing that the bytes are below snd_una and not shifting them.

Fix this by only using skb->protocol if the skb has no vlan tag, or if a vlan tag is present and filter-vlan-tagged bridge netfilter sysctl is enabled.

After application of the patch, programs that allocate big arrays on the stack crash with segfault, for example, this will crash if compiled without optimization: int main() { char array[200000]; array[199999] = 0; return 0; } The reason is that PA-RISC has up-growing stack and the stack is usually the last memory area. In the above example, a page fault happens above the stack. Previously, if we passed too high address to find_vma_prev, it returned NULL and stored the last VMA in *pprev. After "simplify find_vma_prev" change, it stores NULL in *pprev. Consequently, the stack area is not found and it is not expanded, as it used to be before the change. This patch restores the old behavior and makes it return the last VMA in *pprev if the requested address is higher than address of any other VMA.

And in those cases, we're much better off just using the regular "find_vma()", and then "prev" can be looked up by just checking vma->vm_prev. The find_vma_prev() semantics are fairly subtle (see Mikulas' recent commit 83cd904d271b: "mm: fix find_vma_prev"), and the whole "return prev by reference" means that it generates worse code too. Thus this "let's avoid using this inconvenient and clearly too subtle interface when we don't really have to" patch.

This is significant for non-sampling runs where it is possible for the new value to overtake the previous one, causing the delta to be out by up to max_period events. Commit a737823d ("ARM: 6835/1: perf: ensure overflows aren't missed due to IRQ latency") attempted to fix this problem by allowing interrupt handlers to pass an overflow flag to the event update function, causing the overflow calculation to assume that the counter passed through zero when going from prev to new. Unfortunately, this doesn't work when overflow occurs on the perf_task_tick path because we have the flag cleared and end up computing a large negative delta. This patch removes the overflow flag from armpmu_event_update and instead limits the sample_period to half of the max_period for non-sampling profiling runs.

It appears that we fail to get sufficent ioremap space for the framebuffer, and this leads to an oops. This patch should fix the oops and leave a message in the logs we can check for. A future fix would probably to resize the console to a size that we can ioremap.

It causes some odd regression that we have not figured out, and it's too late in the -rc series to try to figure it out now. As reported by Konstantin Khlebnikov, it causes consistent hangs on his laptop (Thinkpad x220: 2x cores + HT). They can be avoided by adding calls to "rebuild_sched_domains();" in cpuset_cpu_[in]active() for the CPU_{ONLINE/DOWN_FAILED/DOWN_PREPARE}_FROZEN cases, but it's not at all clear why, and it makes no sense. Konstantin's config doesn't even have CONFIG_CPUSETS enabled, just to make things even more interesting. So it's not the cpusets, it's just the scheduling domains.

The reason is that it merged the mostly identical versions of delay_32.c and delay_64.c. Though the subtle difference of the result was: static void delay_tsc(unsigned long loops) { - unsigned bclock, now; + unsigned long bclock, now; Now the function uses rdtscl() which returns the lower 32bit of the TSC. On 32bit that's not problematic as unsigned long is 32bit. On 64 bit this fails when the lower 32bit are close to wrap around when bclock is read, because the following check if ((now - bclock) >= loops) break; evaluated to true on 64bit for e.g. bclock = 0xffffffff and now = 0 because the unsigned long (now - bclock) of these values results in 0xffffffff00000001 which is definitely larger than the loops value. That explains Tvortkos observation: "Because I am seeing udelay(500) (_occasionally_) being short, and that by delaying for some duration between 0us (yep) and 491us." Make those variables explicitely u32 again, so this works for both 32 and 64 bit.
