When tcp retransmit timeout(15mins), the connection will be closed. Pending messages may be lost during this time. So we set tcp user timeout to override the retransmit timeout to the max value. This is OK for ocfs2 since we have disk heartbeat, if peer crash, the disk heartbeat will timeout and it will be evicted, if disk heartbeat not timeout and connection idle for a long time, then this means the cluster enters split-brain state, since fence can't happen, we'd better keep the connection and wait network recover.

This patch series is to fix a possible message lost bug in ocfs2 when network go bad. This bug will cause ocfs2 hung forever even network become good again. The messages may lost in this case. After the tcp connection is established between two nodes, an idle timer will be set to check its state periodically, if no messages are received during this time, idle timer will timeout, it will shutdown the connection and try to reconnect, so pending messages in tcp queues will be lost. This messages may be from dlm. Dlm may get hung in this case. This may cause the whole ocfs2 cluster hung. This is very possible to happen when network state goes bad. Do the reconnect is useless, it will fail if network state is still bad. Just waiting there for network recovering may be a good idea, it will not lost messages and some node will be fenced until cluster goes into split-brain state, for this case, Tcp user timeout is used to override the tcp retransmit timeout. It will timeout after 25 days, user should have notice this through the provided log and fix the network, if they don't, ocfs2 will fall back to original reconnect way. This patch (of 3): Some messages in the tcp queue maybe lost if we shutdown the connection and reconnect when idle timeout. If packets lost and reconnect success, then the ocfs2 cluster maybe hung. To fix this, we can leave the connection there and do the fence decision when idle timeout, if network recover before fence dicision is made, the connection survive without lost any messages. This bug can be saw when network state go bad. It may cause ocfs2 hung forever if some packets lost. With this fix, ocfs2 will recover from hung if network becomes good again. Signed-off-by:

If we failed to copy from the structure, writing back the flags leaks 31 bits of kernel memory (the rest of the ir_flags field). In any case, if we cannot copy from/to the structure, why should we expect putting just the flags to work? Also make sure ocfs2_info_handle_freeinode() returns the right error code if the copy_to_user() fails. Fixes: ddee5cdb ('Ocfs2: Add new OCFS2_IOC_INFO ioctl for ocfs2 v8.') Signed-off-by:

New system call depends on crypto. As it did not have a separate config option, CONFIG_KEXEC was modified to select CRYPTO and CRYPTO_SHA256. But now previous patch introduced a new config option for new syscall. So CONFIG_KEXEC does not require crypto. Remove that dependency. Signed-off-by:

Vivek Goyal authored
Currently new system call kexec_file_load() and all the associated code compiles if CONFIG_KEXEC=y. But new syscall also compiles purgatory code which currently uses gcc option -mcmodel=large. This option seems to be available only gcc 4.4 onwards. Hiding new functionality behind a new config option will not break existing users of old gcc. Those who wish to enable new functionality will require new gcc. Having said that, I am trying to figure out how can I move away from using -mcmodel=large but that can take a while. I think there are other advantages of introducing this new config option. As this option will be enabled only on x86_64, other arches don't have to compile generic kexec code which will never be used. This new code selects CRYPTO=y and CRYPTO_SHA256=y. And all other arches had to do this for CONFIG_KEXEC. Now with introduction of new config option, we can remove crypto dependency from other arches. Now CONFIG_KEXEC_FILE is available only on x86_64. So whereever I had CONFIG_X86_64 defined, I got rid of that. For CONFIG_KEXEC_FILE, instead of doing select CRYPTO=y, I changed it to "depends on CRYPTO=y". This should be safer as "select" is not recursive. Signed-off-by:

Sasha Levin has shown oopses on ffffea0003480048 and ffffea0003480008 at mm/memory.c:1132, running Trinity on different 3.16-rc-next kernels: where zap_pte_range() checks page->mapping to see if PageAnon(page). Those addresses fit struct pages for pfns d2001 and d2000, and in each dump a register or a stack slot showed d2001730 or d2000730: pte flags 0x730 are PCD ACCESSED PROTNONE SPECIAL IOMAP; and Sasha's e820 map has a hole between cfffffff and 100000000, which would need special access. Commit c46a7c81 ("x86: define _PAGE_NUMA by reusing software bits on the PMD and PTE levels") has broken vm_normal_page(): a PROTNONE SPECIAL pte no longer passes the pte_special() test, so zap_pte_range() goes on to try to access a non-existent struct page. Fix this by refining pte_special() (SPECIAL with PRESENT or PROTNONE) to complement pte_numa() (SPECIAL with neither PRESENT nor PROTNONE). A hint that this was a problem was that c46a7c81 added pte_numa() test to vm_normal_page(), and moved its is_zero_pfn() test from slow to fast path: This was papering over a pte_special() snag when the zero page was encountered during zap. This patch reverts vm_normal_page() to how it was before, relying on pte_special(). It still appears that this patch may be incomplete: aren't there other places which need to be handling PROTNONE along with PRESENT? For example, pte_mknuma() clears _PAGE_PRESENT and sets _PAGE_NUMA, but on a PROT_NONE area, that would make it pte_special(). This is side-stepped by the fact that NUMA hinting faults skipped PROT_NONE VMAs and there are no grounds where a NUMA hinting fault on a PROT_NONE VMA would be interesting.

spin_lock may be an empty struct for !SMP configurations and so arch_spin_is_locked may return unconditional 0 and trigger the VM_BUG_ON even when the lock is held. Replace spin_is_locked by lockdep_assert_held. We will not BUG anymore but it is questionable whether crashing makes a lot of sense in the uncharge path. Uncharge happens after the last page reference was released so nobody should touch the page and the function doesn't update any shared state except for res counter which uses synchronization of its own.

To avoid potential format string expansion via module parameters, do not use the zpool type directly in request_module() without a format string. Additionally, to avoid arbitrary modules being loaded via zpool API (e.g. via the zswap_zpool_type module parameter) add a "zpool-" prefix to the requested module, as well as module aliases for the existing zpool types (zbud and zsmalloc).

In memblock_find_in_range_node(), we defined ret as int. But it should be phys_addr_t because it is used to store the return value from __memblock_find_range_bottom_up(). The bug has not been triggered because when allocating low memory near the kernel end, the "int ret" won't turn out to be negative. When we started to allocate memory on other nodes, and the "int ret" could be minus. Then the kernel will panic. A simple way to reproduce this: comment out the following code in numa_init(), memblock_set_bottom_up(false); and the kernel won't boot. Reported-by:Xishi Qiu <qiuxishi@huawei.com> Signed-off-by:

Richard and Daniel reported that UML is broken due to changes to resource traversal functions. Problem is that iomem_resource.child can be null and new code does not consider that possibility. Old code used a for loop and that loop will not even execute if p was null. Revert back to for() loop logic and bail out if p is null. I also moved sibling_only check out of resource_lock. There is no reason to keep it inside the lock. Following is backtrace of the UML crash.

Pull block layer fixes from Jens Axboe: "A smaller collection of fixes that have come up since the initial merge window pull request. This contains: - error handling cleanup and support for larger than 16 byte cdbs in sg_io() from Christoph. The latter just matches what bsg and friends support, sg_io() got left out in the merge. - an option for brd to expose partitions in /proc/partitions. They are hidden by default for compat reasons. From Dmitry Monakhov. - a few blk-mq fixes from me - killing a dead/unused flag, fix for merging happening even if turned off, and correction of a few comments. - removal of unnecessary ->owner setting in systemace. From Michal Simek. - two related fixes for a problem with nesting freezing of queues in blk-mq. One from Ming Lei removing an unecessary freeze operation, and another from Tejun fixing the nesting regression introduced in the merge window. - fix for a BUG_ON() at bio_endio time when protection info is attached and the IO has an error. From Sagi Grimberg. - two scsi_ioctl bug fixes for regressions with scsi-mq from Tony Battersby. - a cfq weight update fix and subsequent comment update from Toshiaki Makita" * 'for-linus' of git://git.kernel.dk/linux-block: cfq-iosched: Add comments on update timing of weight cfq-iosched: Fix wrong children_weight calculation block: fix error handling in sg_io fix regression in SCSI_IOCTL_SEND_COMMAND scsi-mq: fix requests that use a separate CDB buffer block: support > 16 byte CDBs for SG_IO block: cleanup error handling in sg_io brd: add ram disk visibility option block: systemace: Remove .owner field for driver blk-mq: blk_mq_freeze_queue() should allow nesting blk-mq: correct a few wrong/bad comments block: Fix BUG_ON when pi errors occur blk-mq: don't allow merges if turned off for the queue blk-mq: get rid of unused BLK_MQ_F_SHOULD_SORT flag blk-mq: fix WARNING "percpu_ref_kill() called more than once!" -

write{b,w,l,q}_relaxed are implemented by some architectures in order to permit memory-mapped I/O writes with weaker barrier semantics than the non-relaxed variants. This patch implements these write macros for Alpha, in the same vein as the relaxed read macros, which are already implemented.

Now IOAPIC driver dynamically allocates IRQ numbers for IOAPIC pins. We need to keep IRQ assignment for PCI devices during runtime power management, otherwise it may cause failure of device wakeups. Commit 3eec5952 "x86, irq, PCI: Keep IRQ assignment for PCI devices during suspend/hibernation" has fixed the issue for suspend/ hibernation, we also need the same fix for runtime device sleep too.

When performing a same-directory rename, it's possible that adding or setting the new directory entry will cause the directory to overflow the inline data area, which causes the directory to be converted to an extent-based directory. Under this circumstance it is necessary to re-read the directory when deleting the old dirent because the "old directory" context still points to i_block in the inode table, which is now an extent tree root! The delete fails with an FS error, and the subsequent fsck complains about incorrect link counts and hardlinked directories. Test case (originally found with flat_dir_test in the metadata_csum test program): # mkfs.ext4 -O inline_data /dev/sda # mount /dev/sda /mnt # mkdir /mnt/x # touch /mnt/x/changelog.gz /mnt/x/copyright /mnt/x/README.Debian # sync # for i in /mnt/x/*; do mv $i $i.longer; done # ls -la /mnt/x/ total 0 -rw-r--r-- 1 root root 0 Aug 25 12:03 changelog.gz.longer -rw-r--r-- 1 root root 0 Aug 25 12:03 copyright -rw-r--r-- 1 root root 0 Aug 25 12:03 copyright.longer -rw-r--r-- 1 root root 0 Aug 25 12:03 README.Debian.longer (Hey!

It turns out that there are some serious problems with the on-disk format of journal checksum v2. The foremost is that the function to calculate descriptor tag size returns sizes that are too big. This causes alignment issues on some architectures and is compounded by the fact that some parts of jbd2 use the structure size (incorrectly) to determine the presence of a 64bit journal instead of checking the feature flags. Therefore, introduce journal checksum v3, which enlarges the descriptor block tag format to allow for full 32-bit checksums of journal blocks, fix the journal tag function to return the correct sizes, and fix the jbd2 recovery code to use feature flags to determine 64bitness. Add a few function helpers so we don't have to open-code quite so many pieces. Switching to a 16-byte block size was found to increase journal size overhead by a maximum of 0.1%, to convert a 32-bit journal with no checksumming to a 32-bit journal with checksum v3 enabled.

When recovering the journal, don't fall into an infinite loop if we encounter a corrupt journal block. Instead, just skip the block and return an error, which fails the mount and thus forces the user to run a full filesystem fsck. Signed-off-by:

In case of delalloc block i_disksize may be less than i_size. So we have to update i_disksize each time we allocated and submitted some blocks beyond i_disksize. We weren't doing this on the error paths, so fix this. testcase: xfstest generic/019 Signed-off-by:
