| 2d6d7f9 | Johannes Weiner | 08 January 2015, 22:32:18 UTC | mm: protect set_page_dirty() from ongoing truncation Tejun, while reviewing the code, spotted the following race condition between the dirtying and truncation of a page: __set_page_dirty_nobuffers() __delete_from_page_cache() if (TestSetPageDirty(page)) page->mapping = NULL if (PageDirty()) dec_zone_page_state(page, NR_FILE_DIRTY); dec_bdi_stat(mapping->backing_dev_info, BDI_RECLAIMABLE); if (page->mapping) account_page_dirtied(page) __inc_zone_page_state(page, NR_FILE_DIRTY); __inc_bdi_stat(mapping->backing_dev_info, BDI_RECLAIMABLE); which results in an imbalance of NR_FILE_DIRTY and BDI_RECLAIMABLE. Dirtiers usually lock out truncation, either by holding the page lock directly, or in case of zap_pte_range(), by pinning the mapcount with the page table lock held. The notable exception to this rule, though, is do_wp_page(), for which this race exists. However, do_wp_page() already waits for a locked page to unlock before setting the dirty bit, in order to prevent a race where clear_page_dirty() misses the page bit in the presence of dirty ptes. Upgrade that wait to a fully locked set_page_dirty() to also cover the situation explained above. Afterwards, the code in set_page_dirty() dealing with a truncation race is no longer needed. Remove it. Reported-by: Tejun Heo <tj@kernel.org> Signed-off-by: Johannes Weiner <hannes@cmpxchg.org> Acked-by: Kirill A.

| 7a3ef20 | Konstantin Khlebnikov | 08 January 2015, 22:32:15 UTC | mm: prevent endless growth of anon_vma hierarchy Constantly forking task causes unlimited grow of anon_vma chain. Each next child allocates new level of anon_vmas and links vma to all previous levels because pages might be inherited from any level. This patch adds heuristic which decides to reuse existing anon_vma instead of forking new one. It adds counter anon_vma->degree which counts linked vmas and directly descending anon_vmas and reuses anon_vma if counter is lower than two. As a result each anon_vma has either vma or at least two descending anon_vmas. In such trees half of nodes are leafs with alive vmas, thus count of anon_vmas is no more than two times bigger than count of vmas. This heuristic reuses anon_vmas as few as possible because each reuse adds false aliasing among vmas and rmap walker ought to scan more ptes when it searches where page is might be mapped.

| fee7e49 | Linus Torvalds | 06 January 2015, 21:00:05 UTC | mm: propagate error from stack expansion even for guard page Jay Foad reports that the address sanitizer test (asan) sometimes gets confused by a stack pointer that ends up being outside the stack vma that is reported by /proc/maps. This happens due to an interaction between RLIMIT_STACK and the guard page: when we do the guard page check, we ignore the potential error from the stack expansion, which effectively results in a missing guard page, since the expected stack expansion won't have been done. And since /proc/maps explicitly ignores the guard page (commit d7824370e263: "mm: fix up some user-visible effects of the stack guard page"), the stack pointer ends up being outside the reported stack area. This is the minimal patch: it just propagates the error. It also effectively makes the guard page part of the stack limit, which in turn measn that the actual real stack is one page less than the stack limit. Let's see if anybody notices. We could teach acct_stack_growth() to allow an extra page for a grow-up/grow-down stack in the rlimit test, but I don't want to add more complexity if it isn't needed.

| 9d31b3c | Linus Lüssing | 13 December 2014, 22:32:15 UTC | batman-adv: fix potential TT client + orig-node memory leak This patch fixes a potential memory leak which can occur once an originator times out. On timeout the according global translation table entry might not get purged correctly. Furthermore, the non purged TT entry will cause its orig-node to leak, too. Which additionally can lead to the new multicast optimization feature not kicking in because of a therefore bogus counter. In detail: The batadv_tt_global_entry->orig_list holds the reference to the orig-node. Usually this reference is released after BATADV_PURGE_TIMEOUT through: _batadv_purge_orig()-> batadv_purge_orig_node()->batadv_update_route()->_batadv_update_route()-> batadv_tt_global_del_orig() which purges this global tt entry and releases the reference to the orig-node. However, if between two batadv_purge_orig_node() calls the orig-node timeout grew to 2*BATADV_PURGE_TIMEOUT then this call path isn't reached. Instead the according orig-node is removed from the originator hash in _batadv_purge_orig(), the batadv_update_route() part is skipped and won't be reached anymore. Fixing the issue by moving batadv_tt_global_del_orig() out of the rcu callback.

| a516488 | Linus Lüssing | 30 October 2014, 04:40:47 UTC | batman-adv: fix multicast counter when purging originators When purging an orig_node we should only decrease counter tracking the number of nodes without multicast optimizations support if it was increased through this orig_node before. A not yet quite initialized orig_node (meaning it did not have its turn in the mcast-tvlv handler so far) which gets purged would not adhere to this and will lead to a counter imbalance. Fixing this by adding a check whether the orig_node is mcast-initalized before decreasing the counter in the mcast-orig_node-purging routine.

| 2c667a3 | Linus Lüssing | 30 October 2014, 05:23:40 UTC | batman-adv: fix delayed foreign originator recognition Currently it can happen that the reception of an OGM from a new originator is not being accepted. More precisely it can happen that an originator struct gets allocated and initialized (batadv_orig_node_new()), even the TQ gets calculated and set correctly (batadv_iv_ogm_calc_tq()) but still the periodic orig_node purging thread will decide to delete it if it has a chance to jump between these two function calls. This is because batadv_orig_node_new() initializes the last_seen value to zero and its caller (batadv_iv_ogm_orig_get()) makes it visible to other threads by adding it to the hash table already. batadv_iv_ogm_calc_tq() will set the last_seen variable to the correct, current time a few lines later but if the purging thread jumps in between that it will think that the orig_node timed out and will wrongly schedule it for deletion already. If the purging interval is the same as the originator interval (which is the default: 1 second), then this game can continue for several rounds until the random OGM jitter added enough difference between these two (in tests, two to about four rounds seemed common). Fixing this by initializing the last_seen variable of an orig_node to the current time before adding it to the hash table.

| 7ce67a3 | Felipe Balbi | 02 January 2015, 22:15:59 UTC | net: ethernet: cpsw: fix hangs with interrupts The CPSW IP implements pulse-signaled interrupts. Due to that we must write a correct, pre-defined value to the CPDMA_MACEOIVECTOR register so the controller generates a pulse on the correct IRQ line to signal the End Of Interrupt. The way the driver is written today, all four IRQ lines are requested using the same IRQ handler and, because of that, we could fall into situations where a TX IRQ fires but we tell the controller that we ended an RX IRQ (or vice-versa). This situation triggers an IRQ storm on the reserved IRQ 127 of INTC which will in turn call ack_bad_irq() which will, then, print a ton of: unexpected IRQ trap at vector 00 In order to fix the problem, we are moving all calls to cpdma_ctlr_eoi() inside the IRQ handler and making sure we *always* write the correct value to the CPDMA_MACEOIVECTOR register. Note that the algorithm assumes that IRQ numbers and value-to-be-written-to-EOI are proportional, meaning that a write of value 0 would trigger an EOI pulse for the RX_THRESHOLD Interrupt and that's the IRQ number sitting in the 0-th index of our irqs_table array. This, however, is safe at least for current implementations of CPSW so we will refrain from making the check smarter (and, as a side-effect, slower) until we actually have a platform where IRQ lines are swapped. This patch has been tested for several days with AM335x- and AM437x-based platforms. AM57x was left out because there are still pending patches to enable ethernet in mainline for that platform. A read of the TRM confirms the statement on previous paragraph.

This makes for example checking devices for random MAC addresses tricky, and you might end up with multiple network interfaces with the same address. This patch tries to fix, or at least improve, the situation by setting the MAC address of devices with this firmware bug to a random address. I tested the patch with two devices that has this firmware bug (Huawei E398 and E392), and network traffic worked fine after changing the address.

In fact the problem was completely unrelated to IPsec. The bug is also reproducible if you just disable TSO/GSO. The problem is that when the MSS goes down, existing queued packet on the TX queue that have not been transmitted yet all look like TSO packets and get treated as such. This then triggers a bug where tcp_mss_split_point tells us to generate a zero-sized packet on the TX queue. Once that happens we're screwed because the zero-sized packet can never be removed by ACKs.

It's causing severe userspace breakage. Namely, all the utilities from wireless-utils which are relying on CONFIG_WEXT (which means tools like 'iwconfig', 'iwlist', etc) are not working anymore. There is a 'iw' utility in newer wireless-tools, which is supposed to be a replacement for all the "deprecated" binaries, but it's far away from being massively adopted. Please see [1] for example of the userspace breakage this is causing. In addition to that, Larry Finger reports [2] that this patch is also causing ipw2200 driver being impossible to build.

It changed the stored return value from a queuecommand call, but it didn't take into account that the return value was used again later on. This patch fixes the bug by changing the later usage. There is a big comment in the middle of scsi_send_eh_cmnd() which does a good job of explaining how the routine works. But it mentions a "rtn = FAILURE" value that doesn't exist in the code.

This patch resolves the issue by creating a copy of the filename which the audit subsystem frees after it is done with the string. At some point it would be nice to resolve this issue with refcounts, or something similar, instead of having to allocate/copy strings, but that is almost surely beyond the scope of a -rcX patch so we'll defer that for later. On the plus side, only audit users should be impacted by the string copying.

Not only this is less than optimal from the API point of view because it is error prone, it is also buggy currently because grab_cache_page_write_begin is using GFP_KERNEL for radix tree and if fgp_flags doesn't contain FGP_NOFS (mostly controlled by fs by AOP_FLAG_NOFS flag) but the mapping_gfp_mask has __GFP_FS cleared then the radix tree allocation wouldn't obey the restriction and might recurse into filesystem and cause deadlocks. This is the case for most filesystems unfortunately because only ext4 and gfs2 are using AOP_FLAG_NOFS. Let's simply remove radix_gfp_mask parameter because the allocation context is same for both page cache and for the radix tree. Just make sure that the radix tree gets only the sane subset of the mask (e.g. do not pass __GFP_WRITE). Long term it is more preferable to convert remaining users of AOP_FLAG_NOFS to use mapping_gfp_mask instead and simplify this interface even further.

However, the logos are __initdata, and have already been freed. This causes sometimes page faults, if the logo memory is not mapped, sometimes other random crashes as the logo data is invalid, and sometimes nothing, if the fbdev decides to reject the logo (e.g. the random value depicting the logo's height is too big). This patch adds a late_initcall function to mark the logos as freed. In reality the logos are freed later, and fbdev probe may be ran between this late_initcall and the freeing of the logos. In that case we will miss drawing the logo, even if it would be possible. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Cc: stable@vger.kernel.org | 29 December 2014, 08:06:55 UTC |

But we can ignore the failure and still go ahead, as in most cases crashkernel will be of same endianess as primary kernel and reseting endianess is not even needed in those cases. This patch adds a new inline function to say if this is kdump path. This function is used at places where such a check is needed.
