2020-10-03net/sched: act_vlan: Add {POP,PUSH}_ETH actionsGuillaume Nault
Implement TCA_VLAN_ACT_POP_ETH and TCA_VLAN_ACT_PUSH_ETH, to respectively pop and push a base Ethernet header at the beginning of a frame. POP_ETH is just a matter of pulling ETH_HLEN bytes. VLAN tags, if any, must be stripped before calling POP_ETH. PUSH_ETH is restricted to skbs with no mac_header, and only the MAC addresses can be configured. The Ethertype is automatically set from skb->protocol. These restrictions ensure that all skb's fields remain consistent, so that this action can't confuse other part of the networking stack (like GSO). Since openvswitch already had these actions, consolidate the code in skbuff.c (like for vlan and mpls push/pop). Signed-off-by: Guillaume Nault <gnault@redhat.com> Signed-off-by: David S.

2020-10-03iov_iter: refactor rw_copy_check_uvector and import_iovecChristoph Hellwig
Split rw_copy_check_uvector into two new helpers with more sensible calling conventions: - iovec_from_user copies a iovec from userspace either into the provided stack buffer if it fits, or allocates a new buffer for it. Returns the actually used iovec. It also verifies that iov_len does fit a signed type, and handles compat iovecs if the compat flag is set. - __import_iovec consolidates the native and compat versions of import_iovec. It calls iovec_from_user, then validates each iovec actually points to user addresses, and ensures the total length doesn't overflow. This has two major implications: - the access_process_vm case loses the total lenght checking, which wasn't required anyway, given that each call receives two iovecs for the local and remote side of the operation, and it verifies the total length on the local side already. - instead of a single loop there now are two loops over the iovecs. Given that the iovecs are cache hot this doesn't make a major difference Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2020-10-02net: introduce helper sendpage_ok() in include/linux/net.hColy Li
The original problem was from nvme-over-tcp code, who mistakenly uses kernel_sendpage() to send pages allocated by __get_free_pages() without __GFP_COMP flag. Such pages don't have refcount (page_count is 0) on tail pages, sending them by kernel_sendpage() may trigger a kernel panic from a corrupted kernel heap, because these pages are incorrectly freed in network stack as page_count 0 pages. This patch introduces a helper sendpage_ok(), it returns true if the checking page, - is not slab page: PageSlab(page) is false. - has page refcount: page_count(page) is not zero All drivers who want to send page to remote end by kernel_sendpage() may use this helper to check whether the page is OK. If the helper does not return true, the driver should try other non sendpage method (e.g. sock_no_sendpage()) to handle the page.

2020-10-02bpf: Introduce pseudo_btf_idHao Luo
Pseudo_btf_id is a type of ld_imm insn that associates a btf_id to a ksym so that further dereferences on the ksym can use the BTF info to validate accesses. Internally, when seeing a pseudo_btf_id ld insn, the verifier reads the btf_id stored in the insn[0]'s imm field and marks the dst_reg as PTR_TO_BTF_ID. The btf_id points to a VAR_KIND, which is encoded in btf_vminux by pahole. If the VAR is not of a struct type, the dst reg will be marked as PTR_TO_MEM instead of PTR_TO_BTF_ID and the mem_size is resolved to the size of the VAR's type. >From the VAR btf_id, the verifier can also read the address of the ksym's corresponding kernel var from kallsyms and use that to fill dst_reg. Therefore, the proper functionality of pseudo_btf_id depends on (1) kallsyms and (2) the encoding of kernel global VARs in pahole, which should be available since pahole v1.18.

2020-10-02net/mlx5: cmdif, Avoid skipping reclaim pages if FW is not accessibleSaeed Mahameed
In case of pci is offline reclaim_pages_cmd() will still try to call the FW to release FW pages, cmd_exec() in this case will return a silent success without actually calling the FW. This is wrong and will cause page leaks, what we should do is to detect pci offline or command interface un-available before tying to access the FW and manually release the FW pages in the driver. In this patch we share the code to check for FW command interface availability and we call it in sensitive places e.g. reclaim_pages_cmd(). Alternative fix: 1. Remove MLX5_CMD_OP_MANAGE_PAGES form mlx5_internal_err_ret_value, command success simulation list. 2. Always Release FW pages even if cmd_exec fails in reclaim_pages_cmd().

2020-10-02net/mlx5: Avoid possible free of command entry while timeout comp handlerEran Ben Elisha
Upon command completion timeout, driver simulates a forced command completion. In a rare case where real interrupt for that command arrives simultaneously, it might release the command entry while the forced handler might still access it. Fix that by adding an entry refcount, to track current amount of allowed handlers. Command entry to be released only when this refcount is decremented to zero. Command refcount is always initialized to one. For callback commands, command completion handler is the symmetric flow to decrement it. For non-callback commands, it is wait_func(). Before ringing the doorbell, increment the refcount for the real completion handler. Once the real completion handler is called, it will decrement it. For callback commands, once the delayed work is scheduled, increment the refcount. Upon callback command completion handler, we will try to cancel the timeout callback. In case of success, we need to decrement the callback refcount as it will never run. In addition, gather the entry index free and the entry free into a one flow for all command types release.

2020-10-02bus/fsl-mc: Add a container setup functionDiana Craciun
Both DPRC driver and VFIO driver use the same initialization code for the DPRC. Introduced a new function which groups this initialization code. The function is exported and may be used by VFIO as well.

2020-10-02bus/fsl-mc: Export dprc_scan/dprc_remove functions to be used by multiple ↵Diana Craciun
entities Currently the DPRC scan function is used only by the bus driver. But the same functionality will be needed by the VFIO driver. To support this, the dprc scan function was exported and a little bit adjusted to fit both scenarios. Also the scan mutex initialization is done when the bus object is created, not in dprc_probe in order to be used by both VFIO and bus driver. Similarily dprc_remove_devices is exported to be used by VFIO.

2020-10-02sysfs: Add sysfs_emit and sysfs_emit_at to format sysfs outputJoe Perches
Output defects can exist in sysfs content using sprintf and snprintf. sprintf does not know the PAGE_SIZE maximum of the temporary buffer used for outputting sysfs content and it's possible to overrun the PAGE_SIZE buffer length. Add a generic sysfs_emit function that knows that the size of the temporary buffer and ensures that no overrun is done. Add a generic sysfs_emit_at function that can be used in multiple call situations that also ensures that no overrun is done. Validate the output buffer argument to be page aligned. Validate the offset len argument to be within the PAGE_SIZE buf.
