On timeout event, schedule a work queue to do the retransmission. Retransmission code closely resembles the sendmsg() implementation and re-uses mptcp_sendmsg_frag, providing a dummy msghdr - for flags' sake - and peeking the relevant dfrag from the rtx head. Signed-off-by:

This will simplify mptcp-level retransmission implementation in the next patch. If dfrag is provided by the caller, skip kernel space memory allocation and use data and metadata provided by the dfrag itself. Because a peer could ack data at TCP level but refrain from sending mptcp-level ACKs, we could grow the mptcp socket backlog indefinitely. We should thus block mptcp_sendmsg until the peer has acked some of the sent data. In order to be able to do so, increment the mptcp socket wmem_queued counter on memory allocation and decrement it when releasing the memory on mptcp-level ack reception. Because TCP performns sndbuf auto-tuning up to tcp_wmem_max[2], make this the mptcp sk_sndbuf limit. In the future we could add experiment with autotuning as TCP does in tcp_sndbuf_expand(). v2 -> v3: - remove 'inline' in foo.c files (David S. Miller) Co-developed-by:

After adding wmem accounting for the mptcp socket we could get into a situation where the mptcp socket can't transmit more data, and mptcp_clean_una doesn't reduce wmem even if snd_una has advanced because it currently will only remove entire dfrags. Allow advancing the dfrag head sequence and reduce wmem, even though this isn't correct (as we can't release the page). Because we will soon block on mptcp sk in case wmem is too large, call sk_stream_write_space() in case we reduced the backlog so userspace task blocked in sendmsg or poll will be woken up. This isn't an issue if the send buffer is large, but it is when SO_SNDBUF is used to reduce it to a lower value. Note we can still get a deadlock for low SO_SNDBUF values in case both sides of the connection write to the socket: both could be blocked due to wmem being too small -- and current mptcp stack will only increment mptcp ack_seq on recv. This doesn't happen with the selftest as it uses poll() and will always call recv if there is data to read. Signed-off-by:

The timer will be used to schedule retransmission. It's frequency is based on the current subflow RTO estimation and is reset on every una_seq update The timer is clearer for good by __mptcp_clear_xmit() Also clean MPTCP rtx queue before each transmission. Signed-off-by:

Keep the send page fragment on an MPTCP level retransmission queue. The queue entries are allocated inside the page frag allocator, acquiring an additional reference to the page for each list entry. Also switch to a custom page frag refill function, to ensure that the current page fragment can always host an MPTCP rtx queue entry. The MPTCP rtx queue is flushed at disconnect() and close() time Note that now we need to call __mptcp_init_sock() regardless of mptcp enable status, as the destructor will try to walk the rtx_queue. v2 -> v3: - remove 'inline' in foo.c files (David S.

Subflow creation may be initiated by the path manager when the primary connection is fully established and a remote address has been received via ADD_ADDR. Create an in-kernel sock and use kernel_connect() to initiate connection. Passive sockets can't acquire the mptcp socket lock at subflow creation time, so an additional list protected by a new spinlock is used to track the MPJ subflows. Such list is spliced into conn_list tail every time the msk socket lock is acquired, so that it will not interfere with data flow on the original connection. Data flow and connection failover not addressed by this commit. Co-developed-by:

Process the MP_JOIN option in a SYN packet with the same flow as MP_CAPABLE but when the third ACK is received add the subflow to the MPTCP socket subflow list instead of adding it to the TCP socket accept queue. The subflow is added at the end of the subflow list so it will not interfere with the existing subflows operation and no data is expected to be transmitted on it. Co-developed-by:

Add enough of a path manager interface to allow sending of ADD_ADDR when an incoming MPTCP connection is created. Capable of sending only a single IPv4 ADD_ADDR option. The 'pm_data' element of the connection sock will need to be expanded to handle multiple interfaces and IPv6. Partial processing of the incoming ADD_ADDR is included so the path manager notification of that event happens at the proper time, which involves validating the incoming address information. This is a skeleton interface definition for events generated by MPTCP. Co-developed-by:

A recent commit e8937681 ("devlink: prepare to support region operations") used the region_cr_space_str and region_fw_health_str variables as initializers for the devlink_region_ops structures. This can result in compiler errors: drivers/net/ethernet/mellanox//mlx4/crdump.c:45:10: error: initializer element is not constant .name = region_cr_space_str, ^ drivers/net/ethernet/mellanox//mlx4/crdump.c:45:10: note: (near initialization for ‘region_cr_space_ops.name’) drivers/net/ethernet/mellanox//mlx4/crdump.c:50:10: error: initializer element is not constant .name = region_fw_health_str, The variables were made to be "const char * const", indicating that both the pointer and data were constant. This was enough to resolve this on recent GCC (gcc (GCC) 9.2.1 20190827 (Red Hat 9.2.1-1) for this author). Unfortunately this is not enough for older compilers to realize that the variable can be treated as a constant expression. Fix this by introducing macros for the string and use those instead of the variable name in the region ops structures. Reported-by:

This was done so that pfn_page() can work correctly with kernel config that disables SPARSEMEM_VMEMMAP. With that config pfn_to_page does __section_mem_map_addr(__sec) + __pfn; where static inline struct page *__section_mem_map_addr(struct mem_section *section) { unsigned long map = section->section_mem_map; map &= SECTION_MAP_MASK; return (struct page *)map; } Now with SPASEMEM_VMEMAP enabled, mem_section->usage->subsection_map is used to check the pfn validity (pfn_valid()). Since section_deactivate release mem_section->usage if a section is fully deactivated, pfn_valid() check after a subsection_deactivate cause a kernel crash. static inline int pfn_valid(unsigned long pfn) { ... return early_section(ms) || pfn_section_valid(ms, pfn); } where static inline int pfn_section_valid(struct mem_section *ms, unsigned long pfn) { int idx = subsection_map_index(pfn); return test_bit(idx, ms->usage->subsection_map); } Avoid this by clearing SECTION_HAS_MEM_MAP when mem_section->usage is freed. For architectures like ppc64 where large pages are used for vmmemap mapping (16MB), a specific vmemmap mapping can cover multiple sections. Hence before a vmemmap mapping page can be freed, the kernel needs to make sure there are no valid sections within that mapping. Clearing the section valid bit before depopulate_section_memap enables this.

Depending on CONFIG_VMAP_STACK and the THREAD_SIZE / PAGE_SIZE ratio the space for task stacks can be allocated using __vmalloc_node_range(), alloc_pages_node() and kmem_cache_alloc_node(). In the first and the second cases page->mem_cgroup pointer is set, but in the third it's not: memcg membership of a slab page should be determined using the memcg_from_slab_page() function, which looks at page->slab_cache->memcg_params.memcg . In this case, using mod_memcg_page_state() (as in account_kernel_stack()) is incorrect: page->mem_cgroup pointer is NULL even for pages charged to a non-root memory cgroup. It can lead to kernel_stack per-memcg counters permanently showing 0 on some architectures (depending on the configuration). In order to fix it, let's introduce a mod_memcg_obj_state() helper, which takes a pointer to a kernel object as a first argument, uses mem_cgroup_from_obj() to get a RCU-protected memcg pointer and calls mod_memcg_state(). It allows to handle all possible configurations (CONFIG_VMAP_STACK and various THREAD_SIZE/PAGE_SIZE values) without spilling any memcg/kmem specifics into fork.c . Note: This is a special version of the patch created for stable backports. It contains code from the following two patches: - mm: memcg/slab: introduce mem_cgroup_from_obj() - mm: fork: fix kernel_stack memcg stats for various stack implementations [guro@fb.com: introduce mem_cgroup_from_obj()] Link: http://lkml.kernel.org/r/20200324004221.GA36662@carbon.dhcp.thefacebook.com Fixes: 4d96ba35 ("mm: memcg/slab: stop setting page->mem_cgroup pointer for slab pages") Signed-off-by:

This appears to be a mistake in commit faced7e0 ("mm: hugetlb controller for cgroups v2"). Essentially that commit does a hugetlb_cgroup_from_counter assuming that page_counter_try_charge has initialized counter. But if that has failed then it seems will not initialize counter, so hugetlb_cgroup_from_counter(counter) ends up pointing to random memory, causing kasan to complain. The solution is to simply use 'h_cg', instead of hugetlb_cgroup_from_counter(counter), since that is a reference to the hugetlb_cgroup anyway. After this change kasan ceases to complain.

We see multiple issues with the implementation/interface to compute whether a memory block can be offlined (exposed via /sys/devices/system/memory/memoryX/removable) and would like to simplify it (remove the implementation). 1. It runs basically lockless. While this might be good for performance, we see possible races with memory offlining that will require at least some sort of locking to fix. 2. Nowadays, more false positives are possible. No arch-specific checks are performed that validate if memory offlining will not be denied right away (and such check will require locking). For example, arm64 won't allow to offline any memory block that was added during boot - which will imply a very high error rate. Other archs have other constraints. 3. The interface is inherently racy. E.g., if a memory block is detected to be removable (and was not a false positive at that time), there is still no guarantee that offlining will actually succeed. So any caller already has to deal with false positives. 4. It is unclear which performance benefit this interface actually provides. The introducing commit 5c755e9f ("memory-hotplug: add sysfs removable attribute for hotplug memory remove") mentioned "A user-level agent must be able to identify which sections of memory are likely to be removable before attempting the potentially expensive operation." However, no actual performance comparison was included. Known users: - lsmem: Will group memory blocks based on the "removable" property. [1] - chmem: Indirect user. It has a RANGE mode where one can specify removable ranges identified via lsmem to be offlined. However, it also has a "SIZE" mode, which allows a sysadmin to skip the manual "identify removable blocks" step. [2] - powerpc-utils: Uses the "removable" attribute to skip some memory blocks right away when trying to find some to offline+remove. However, with ballooning enabled, it already skips this information completely (because it once resulted in many false negatives). Therefore, the implementation can deal with false positives properly already. [3] According to Nathan Fontenot, DLPAR on powerpc is nowadays no longer driven from userspace via the drmgr command (powerpc-utils). Nowadays it's managed in the kernel - including onlining/offlining of memory blocks - triggered by drmgr writing to /sys/kernel/dlpar. So the affected legacy userspace handling is only active on old kernels. Only very old versions of drmgr on a new kernel (unlikely) might execute slower - totally acceptable. With CONFIG_MEMORY_HOTREMOVE, always indicating "removable" should not break any user space tool. We implement a very bad heuristic now. Without CONFIG_MEMORY_HOTREMOVE we cannot offline anything, so report "not removable" as before. Original discussion can be found in [4] ("[PATCH RFC v1] mm: is_mem_section_removable() overhaul"). Other users of is_mem_section_removable() will be removed next, so that we can remove is_mem_section_removable() completely.

claim_swapfile() currently keeps the inode locked when it is successful, or the file is already swapfile (with -EBUSY). And, on the other error cases, it does not lock the inode. This inconsistency of the lock state and return value is quite confusing and actually causing a bad unlock balance as below in the "bad_swap" section of __do_sys_swapon(). This commit fixes this issue by moving the inode_lock() and IS_SWAPFILE check out of claim_swapfile(). The inode is unlocked in "bad_swap_unlock_inode" section, so that the inode is ensured to be unlocked at "bad_swap". Thus, error handling codes after the locking now jumps to "bad_swap_unlock_inode" instead of "bad_swap". ===================================== WARNING: bad unlock balance detected! 5.5.0-rc7+ #176 Not tainted ------------------------------------- swapon/4294 is trying to release lock (&sb->s_type->i_mutex_key) at: __do_sys_swapon+0x94b/0x3550 but there are no more locks to release! other info that might help us debug this: no locks held by swapon/4294. stack backtrace: CPU: 5 PID: 4294 Comm: swapon Not tainted 5.5.0-rc7-BTRFS-ZNS+ #176 Hardware name: ASUS All Series/H87-PRO, BIOS 2102 07/29/2014 Call Trace: dump_stack+0xa1/0xea print_unlock_imbalance_bug.cold+0x114/0x123 lock_release+0x562/0xed0 up_write+0x2d/0x490 __do_sys_swapon+0x94b/0x3550 __x64_sys_swapon+0x54/0x80 do_syscall_64+0xa4/0x4b0 entry_SYSCALL_64_after_hwframe+0x49/0xbe RIP: 0033:0x7f15da0a0dc7 Fixes: 1638045c ("mm: set S_SWAPFILE on blockdev swap devices") Signed-off-by:Naohiro Aota <naohiro.aota@wdc.com> Signed-off-by:

Daniel Borkmann says: ==================== pull-request: bpf 2020-03-27 The following pull-request contains BPF updates for your *net* tree. We've added 3 non-merge commits during the last 4 day(s) which contain a total of 4 files changed, 25 insertions(+), 20 deletions(-). The main changes are: 1) Explicitly memset the bpf_attr structure on bpf() syscall to avoid having to rely on compiler to do so. Issues have been noticed on some compilers with padding and other oddities where the request was then unexpectedly rejected, from Greg Kroah-Hartman. 2) Sanitize the bpf_struct_ops TCP congestion control name in order to avoid problematic characters such as whitespaces, from Martin KaFai Lau. ==================== Signed-off-by:
